Obiettivi formativi
The aim of the course is to enable students to master advanced engineering methods for investigating the dynamics of mechanical systems, with a special focus on vibration of continuous structures and stability analysis of systems subjected to non-linear force fields. An introduction to three-dimensional rigid body dynamics and multibody techniques is also provided. The course covers theoretical models, discretisation techniques and numerical solutions based on the finite element method. Particular attention is given to practical examples and engineering applications, especially in the field of structural dynamics and rotordynamics. Each topic is treated both theoretically and practically, through traditional lectures, class exercises, experimental labs and computer room sessions.
By the end of the course, students will learn contents and practices according to what defined in the learning objectives. In terms of acquired knowledge and understanding, students will develop a knowledge of the modelling approaches to vibration analysis of continuous systems (DD1) and the ability to handle vibration problems for arbitrary combinations of geometrical configurations, structural properties and boundary conditions (DD2); in addition, students will understand the basic physical principles and the mathematical approach to the stability analysis of systems subjected to non-linear force fields (DD1); finally, they will get familiar with the phenomena involved in two of the most significant issues of rotordynamics (i.e. bending critical speeds and oil film instability) as well as the fundamental engineering approaches to rotor balancing and dynamic modelling of fluid lubricated journal bearings (DD1). Concerning the ability to apply the acquired knowledge and understanding, students will develop the ability to apply theoretical knowledge to the analysis of vibration problems in complex mechanical systems and to make judgements concerning the possible alternative choices for modelling a real structure/machinery (DD2, DD3). Through the experimental lab activities, students will learn how to process experimental data from dynamic tests and how to extract the information regarding the modal parameters of a vibrating structure, i.e. natural frequencies, damping ratios, mode shapes (DD2). Finally, students will improve their communication skills, being able to develop skills in summarizing and presenting the results obtained during the lab activities (DD4).

The course aims to provide the students with the necessary tools for the design and assessment of machine components, both under static and fatigue loading. The basics of mechanical design are upgraded in order to include advanced theory of elasticity, finite element analysis, design methods for static and fatigue loads (multiaxial and variable amplitude loading) and tools for assessing the influence of defects on static and fatigue resistance. Theory of elasticity is extended in order to make it possible to evaluate stresses in typical mechanical components like pressure vessels, welded junctions, power transmission shafts and components containing cracks. The students will also apply finite element analyses to validate preliminary structural analyses and carry out a detailed structural assessment of some components.
By the end of the course, students will learn contents and practices according to what defined in the leaning objectives. In terms of acquired knowledge and understanding, students will be able to: select the methods able to solve a statically indeterminate structure; acquite the concept of instability of compressed structural members understand the limitations of a given FE numerical model of structure component; choose correctly the criteria for fatigue assessment of a mechanical component; understand the concepts of flaw criticality and the material behaviour in presence of a singularity; understand the main parameters that control the structural behaviour a component in presence of a flaw. Concerning the ability to apply the acquired knowledge and understanding, students will be able to: sketch the structural scheme of a structure/component and how it should be modelled; examine and perform assessment of machine components subjected to static and fatigue loading; solve practical design applications by using different tools (analytical, numerical and experimental) and critically analyze the results; determine the critical flaw size for a component subjected to static or fatigue loads; fatigue assessment of a welded structure with the concepts of nominal stress. Through activities of laboratory tests and of Finite Element Method applications, students will also acquire the skills to formulate a judgment, meaning to analyse a problem with different tools to understand their assumptions and limitations, and to analyse and critically discuss the results. Furthermore, through the assigned case studies, students will gain the ability to autonomously make appropriate choices for the design of mechanical components and assess their fitness when subjected to static and fatigue loadings.

Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere Prova orale obbligatoria Progetto/i - Elaborato/i obbligatorio, di gruppo, con revisioni periodiche, senza presentazione/discussione finale Students pass the course after successfully taking a mandatory written test, where they must solve some numerical problems and answer some theoretical questions. The written test is carried out on paper in a closed-book fashion: students can only use a cheat sheet provided by the professor. The only allowed electronic device is a standard calculator (no scientific calculators allowed). Both the written test and the oral exam are attended in presence. Via this written test, it is possible to test students’ acquired knowledge and understanding of the course basics and its application based on analytical models. The test is composed of some problems that must be solved by giving numerical answers and by multiple-choice theoretical questions to verify the basics. The written test is successful if its grade Gw > 17/30. If Gw > 17/30, the written test is followed by a mandatory oral discussion, otherwise the student fails the exam and goes to the next call. Via the oral exam, it is possible to test students’ ability to autonomously form judgements and the ability to communicate learnt contents. Students have to answer two main questions formulated by the teacher on two manufacturing processes. The oral exam gives a grade Go ≥ 18/30. If Go < 18/30, the student fails the exam and goes to the next call. The written test grade is canceled in this case and the students has to retake the written test. The final grade Gf is calculated as a weighted average of Gw and Go. The mandatory Lab Work can yield up to 2 additional points (Lw). Since the Lab Work is mandatory, every student is required to do it to pass the exam. The Lab Work must be submitted at the end of the course and before the first exam call according to the date declared by the professor during the course. If the Lab Work is not sufficient, the group cannot attend the first exam call and receives indications by the professor on how to fix it. In case of absence from certain laboratory sessions, the student can retrieve the related material through the other group colleagues and/or via WeBeep. The professor considers the number of absences from the laboratories and, after consulting all group members, will decide whether to consider the requirement for the repeatedly absent student to complete the Lab Work satisfied. Once assessed that the requirement is satisfied, the Lab Work grade of the student with some absences is scaled according to the percentage of attended lab activities. The final grading formula is: Gf = 0.25Gw + 0.75Go + Lw.

The course aims at developing the competences necessary to apply the basic Project Management techniques and tools to a complex project. In increasingly volatile markets, project management needs special attention including change-enabling methodologies into traditional processes. Consequently, the course deals with the traditional (or plan driven) processes of project planning and control (scope, time, resource, cost, quality, risk, cash flow, stakeholder, communication...) and with Agile (or change-driven) project management processes that facilitate the management of project scope changes. The waterfall and agile tools and techniques seen in class will be practiced with two approach:
the analysis of case studies of projects carried out in traditional sectors (Oil & Gas, plant engineering, nuclear, energy).
the participation to an hackathon where each groups’ project work will be presented to an external commission The course fits into the overall program curriculum pursuing some of the defined general goals. In particular, the course contributes to the development of the following capabilities: Understand context, functions, processes in a business and industrial environment and the impact of those factors on business performance Design solutions applying a scientific and engineering approach (Analysis, Learning, Reasoning, and Modeling capability deriving from a solid and rigorous multidisciplinary background) to face problems and opportunities in a business and industrial environment Interact in a professional, responsible, effective and constructive way in a working environment, also motivating group members The course is organized developing both the traditional PM approach and the Agile one. In particolar the agile approach is a stand alone course named Agile Project Management.
By the end of the course, students will learn contents and practices according to what defined in the learning objectives. Use properly Plan Driven & Change Driven Project Management language, understanding management processes involved in a project, understanding interdependencies between operational and managerial processes, capability to correctly apply techniques and tools available in project management. In terms of acquired knowledge and understanding, students will be able to d evelope with both traditional and agile methodologies plan for managing different types of complex project involving the main knowledge areas of project management (scope of work, time, progress, cost, resources, cash flow, risk, etc.) and to e stimate project performance and evaluate recovery plan during project execution. Concerning the ability to apply the acquired knowledge and understanding, students will be able to select the methodology (plan driven or agile) that best suit different types of projects. Through the project work developement students will also acquire the skills to formulate a judgment, on implementing an effective two-way communication: with colleagues for the development of the project work, with the managers of the companies involved in the competition for the participation to the hackathon. Finally, students will improve their communication skills, being able to communicate both with other students during the project work development and with professionals during the final hackathon.

Obiettivi formativi
The course educates students to become professional data scientits by reviewing several statistical models, methods and algortihms aimed at the statistical analysis of mutivariate data. The aim is twofold: first, to provide future data scientists with the mathematical knowledge and understanding necessary for making proper judgments when selecting appropriate methods and algorithms, producing sensible interpretations of the results generated by their application and grasping their strenghts and weaknesses and, second, to enhace the students ability in applying the knowledge and understanding of the statistical approach to data analysis by emphasizing real life and engineering applications where statistical methods and modern computer packages permit to elicit information from multivariate data through complex statistical analyses. The course is offered in two versions, for 8 CFU and 10 CFU respectively. Both versions are named Applied Statistics and are described in the present document. In the 8 CFU version, the course will cover classical topics of Multivariate Data Analysis (e.g.: dimension reduction, inference for regression, supervised and unsupervised classification) with overtures to the modern treatment of multiple inference (FDR) or to novel statistical learning methods and algorithms (e.g. support vector machines, ensemble leraning methods). To these contents, the 10 CFU version of the course adds three modules of Advances in Statistical Learning, leveraging on seminars offered by experts of the fields (e.g.: Linear Mixed Models, Functional Data Analysis, Spatial Statistics). Through an extensive recourse to blendend learning and flipped classroom innovative teaching, both during the lectures and the lab sessions, the course will enahace the students ability in autonomous learning; this will also be accomplished by perusing new teaching media like the MOOC on Statistical Learning by Hastie and Tibshirani referenced in the Bibliography. Particular emphasis is given to the devolopment of a responsible and efficient attitude toward work in a multidisciplinary environment where the data scientist collaborates on a peer-to-peer basis with other engineers and scientists for the modeling and understanding of complex phenomena of scientific or industrial interest. Hence, the course requires team work on real data statistical analyses, either in interaction with industrial partners of the statistical research group of the Department of Mathematics or in collaboration with scientists and engineers demanding a data-driven approach to the solution of their research problem. Work-in-progress of the teams will be periodically discussed in class, drawing attention not only on the appropriatness of the statistical methods and algorithms, but also on the communication skills of the teams when informing an audience of peers. The course fits into the overall program curriculum pursuing some of the defined general learning goals. In particular, the course contributes to the development of the following capabilities: Design models and utilize information from experimental data for inferential estimation, verification and adaptation of the models and for their heuristic developments; Provide the statistical interpretation and simulation of scenarios for the treatment of data in situations of high complexity; Use R for the analysis and treatment of complex data.
Both versions of the course have the following common learning goals:
At the end of the course students are expected to be able to design - and run with R - data analyses aimed at: reducing the dimensionality of a dataset, solving a classification problem, both supervised or unsupervised, making multiple inference on multiple mean vectors or their components, choosing the most appropriate regression model and fitting it while making inference on its components, handling classical (OLS) or more modern approaches to model building and selection (ridge regression and lasso). Leveraging on their engineering forma mentis and on the skills in data analysis acquired in the course, students are expected to be able to evaluate the practical and statistical significance of the final result of their data analysis, to quantify its uncertainty analytically or through simulation, e.g. by cross-validation, and to diagnose its potential shortcomings, either when used to provide an empirical explanation of the industrial or scientific problem under study or when the main goal of the analysis is to formulate predictions.
To prepare for responsible and efficient interactions in a working environment, every student is required to take part in a real data analysis project developed by an independently formed team of 3-5 members. The work in progress of the projects will be collectively discussed during general meetings scheduled along the course; final analyses and results will be presented in a workshop which will take place at the end of the course.
Students are expected to be able to communicate and transfer the results and interpretations of their data analysis to a wider audience of experts, using effective graphical or analytical means, suitable for the problem under study, the findings of the analysis and, finally, the audience. Moreover, the students of the 10 CFU version of the course are expected to have a basic understanding of the more complex issues - and the methods and algorithms developed to solve them - characterizing the statistical analysis of data when heterogeneity and temporal or spatial dependence is of importance or when data do not belong to the finite dimensional Euclidean setting considered in the classical Multivariate Data Analysis framework, like in the case of functional data.

In the 10 CFU version of the course, the above topics are complemented with the following three modules of Advances in Statistical Learning: 6) Linear Mixed Models. Enriching the covariance structure of a linear model to take into account heteroschedasticity and dependence, random effects, hierarchical grouping structures, longitudinal data. 7) Functional Data Analysis.

Through the course, students are required to work in team on a real data analysis project whose progress will be shown periodically to the class.
Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere Progetto/i - Elaborato/i obbligatorio, di gruppo, con revisioni periodiche, con presentazione/discussione finale The exam consists of two parts: (a) A written exam. The written exam consists of questions (theory and practice) and of a few data analysis problems to be individually solved with R; two problems for the students following the 8 CFU versions of the course, three problems - with extra time - for those registered in the 10 CFU version. For the students taking the course for 10 CFU, the extra problem will be related to the three advanced topics treated in the modules characterizing their additional 2 CFU; working on this problem is mandatory to pass the exam of the 10 CFU version of the course. For all students, the use of a personal computer is allowed as well as that of books, personal notes etc. In the written exam the student must show the ability to conduct a stylized data analysis, by selecting the appropriate methods and algorithms - among those introduced in the course - for solving the problems, by running the algorithms with R, by identifying the significant results and by reporting them with the precision and property of language which characterize the technical and scientific communication. (b) Team project evaluation. Projects will be collectively evaluated by the teachers of the course and by the students participating to a final workshop at the end of the course. During the presentation of their projects, teams must prove their ability to conduct and report a real life statistical data analysis, showing knowledge and understanding of the problem at hand and the nature of the data, proper judgment for the selection of the appropriate methods and algorithms, sensible interpretations of the generated results - grasping not only their strenghts but also their weaknesses - and, finally, communication skills when informing an audience of peers. To pass the exam the student must pass each part of the exam with a score greater than or equal to 18/30; the final score is then obtained as the weighted average of the two scores, with weights respectively equal to 0.6 for the written exam and 0.4 for the project evaluation.

The course describes the methodologies to plan, conduct and analyze controlled experiments to determine which factors influence key performance indicators (response) of the product, process or service. Once the relevant factors are selected, the course proposes methodologies for optimization; that is, selecting the levels of the important factors producing the best values of the response. The possibility to optimize through an evolutive experimentation is illustrated using RSM (Response Surface Methodology) Many physical processes are difficult or even impossible to study by usual experimental methods. As computing power has increased, it has become possible to model processes/products/services by sophisticated and time consuming computer codes which act as a proxy for the reality. Also in these cases it is necessary to design appropriately the experiment to save the computational effort. Space filling algorithms are used. The analysis of data has some differences compared to the analysis of physical experiment data as computer experiments have deterministic responses. To analyse this kind of data, Kriging or Gaussion process models must be used. A final look to combining different data sources of information ( multifidelity data, including experts’ opinions, computer simulations and experimental data) for process optimization is included. With the reduced lifetime of innovative technologies, the significant increase of data availability and the needs to speed up the time-to-market for new solutions, this course provides a must-have toolkit for engineers.
Lectures will provide the basis for originality in applying ideas, sometimes in a research context ( Knowledge and understanding ), in the Design and Analysis of Experiments field. Classwork in computer room will develop the student problem solving abilities in a familiar environment ( Applying Knowledge and understanding ). Some problems will be proposed and the students will be required to solve them under a light guidance of a tutor. The student will use State of Art Softwares to make computations (SAS-JMP, MINITAB, MATHEMATICA or MATLAB).
Programma
Part 1 – Design and Analysis of Experiments (DOE) Introduction to Designed Experiments The ANalysis Of VAriance (ANOVA) for single factor and single response Factorial experiments and Blocking for single response and multiple factors Reducing the experimental effort via fractional factorial experiments Fundamentals of Linear Models Part 2 – Response Surface Methodology (RSM) and Design and Analysis of Computer Experiments (DACE) Advanced Linear Models Evolutive Experimentation: RSM (Response Surface Methodology) Robust Design and Multiple Response Optimization Design of Computer experiments: space filling solutions Analysis of Computer Experiment Data: Gaussian Processes and Kriging models Advanced topics for Statistical Optimization
Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere Written Test The written test will verify if the students have got the Knowledge and understanding and Applying Knowledge and understanding abilities. In the Written test the students must solve, usually, 4 problems in computer room. Usually: in two problems the students are required to analyse one or more data set containing, sometimes, outliers or incomplete data; in one problem the students are required to design an experiment and discuss its properties; one problem is mainly theoretical and the students are required to prove some quite simple property not seen before. Each problem will have a certain mark and the final test mark will be the sum of the four problem marks. If the sum of grades is 33 the student will get a final test grade of 30 with "lode" If the grade equal to or less than 10, the student must go to the next exam session. The exam will be " Open Book ".

Obiettivi formativi
In the domain of micro and nanosystems, classical mechanical models no longer suffice to predict material behavior. This course provides students with the fundamental principles of quantum mechanics and solid-state physics, which are essential for a rigorous microscopic description of matter. Acquiring these analytical tools enables future mechanical engineers to comprehend, predict, and exploit the novel physical phenomena that emerge exclusively at the micro- and nano-scale. The course is organized into three progressive phases, bridgeing the gap between classical engineering backgrounds and advanced modern physics: The Classical Crisis and the Quantum Transition: Initiating from classical electromagnetism (Maxwell’s equations and electromagnetic waves), the course examines the pivotal experiments of the early 1900s that exposed the limitations of classical physics—including black-body radiation, the photoelectric and Compton effects, electron diffraction, and atomic spectra. Fundamentals of Quantum Mechanics: Students will master core quantum principles, such as wave-particle duality, operators and observables, the Schrödinger equation, and the Heisenberg uncertainty principle, applying them to decipher atomic and condensed matter phenomena. Solid-State Physics and Material Properties: The course introduces the quantum theory of solids, focusing on crystal structures, symmetry, Bloch’s theorem, and electronic band structures. This framework is utilized to explain the underlying mechanisms governing the electrical and thermal properties of materials. The course balances theoretical rigor with an engineering perspective by analyzing selected state-of-the-art applications within micro and nanotechnology. Utilizing innovative pedagogical approaches, including the flipped classroom method, the course actively engages students in evaluating their comprehension of the material. This interactive framework is designed to foster critical thinking, training students to select and apply the appropriate analytical approach—whether classical, semiclassical, or quantum—to solve complex, real-world engineering problems.
DD1 (Knowledge and understanding): acquisition of the fundamental principles of quantum mechanics and condensed matter physics. DD2 (Applying knowledge and understanding): application of quantum models to the description of microscopic systems and material properties. DD3 (Making judgements): ability to critically interpret physical models and their domain of validity in modern physics contexts. DD4 (Communication skills): use of appropriate scientific language and formalism in describing quantum and solid-state phenomena. DD5 (Learning skills): development of autonomous learning abilities for advanced topics in theoretical and applied physics.
Programma
The curriculum is strategically structured into three interconnected modules, transitioning from established classical principles to advanced quantum engineering frameworks. This rigorous theoretical foundation is systematically paired with practical problem-solving sessions, analytical exercises, and specialized case studies to ensure a comprehensive, quantitative understanding of physical phenomena. Module 1 | Classical Electromagnetism This module establishes the classical baseline and field-theory fundamentals necessary to understand wave propagation and radiation-matter interaction. Maxwell's Equations: A comprehensive review of electrostatics and magnetostatics, leading to Faraday-Neumann-Lenz's law, the Ampère-Maxwell law, and the unified framework of Maxwell's equations in vacuum and matter. Wave Physics: Fundamental principles of the wave equation, complex representation, interference phenomena, and the behavior of traveling and standing waves. Electromagnetic Waves: Propagation of plane waves, energy transport via Poynting's theorem, and the principles of interference and diffraction. Engineering Applications: Structural characterization via X-ray diffraction. Module 2 | Fundamentals of Quantum Mechanics This module explores the foundational crisis of classical physics and introduces the mathematical and conceptual apparatus of quantum mechanics to explain atomic and molecular structures. The Breakdown of Classical Physics: Empirical evidence from electron diffraction, the photoelectric effect, the Compton effect, black-body radiation, and discrete atomic spectra. Wave-Particle Duality: Quantum nature of light (photons) and the De Broglie wavelength of matter. The Schrödinger Equation: Wave functions, quantum operators, stationary states, expectation values, Born's statistical interpretation, and the continuity equation. Operators and Observables: Properties of Hermitian operators, commutators, the Heisenberg uncertainty principle, and Ehrenfest’s theorem. Canonical Case Studies: Energy quantization and dynamics in potential wells, particles in a box, harmonic oscillators, and quantum tunneling. The Hydrogen Atom: The Bohr model legacy, angular momentum quantization, quantum numbers, ground/excited states, and atomic orbitals. Multi-Electron Systems & Molecules: Electron spin, the Pauli exclusion principle, the periodic table architecture, the ionized hydrogen molecule, molecular orbital theory, and structural stability. Engineering Applications: Diagnostic and analytical techniques in atomic spectroscopy. Module 3 | Introduction to Solid-State Physics The final module applies quantum mechanics to collective crystalline systems, establishing the microscopic origins of macroscopic material properties essential for micro- and nanosystems. Quantum Theory of Crystals: Periodicity, Bloch’s theorem, the tight-binding approximation, the free-electron gas model, electronic band structures, and dispersion relations defining metallic, semiconducting, and insulating states. Optical Properties: Microscopic mechanisms governing material reflectance and transparency. Electrical Properties: Electron dynamics within crystal lattices, electrical conductivity mechanisms, effective mass concept, and hole transport. Thermal Properties: Lattice and electronic contributions to the heat capacity of metals. Engineering Applications: Modeling, analysis, and characterization of advanced crystal structures.
Modalità d'esame

Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere Progetto/i - Elaborato/i obbligatorio, individuale, senza revisioni periodiche, con presentazione/discussione finale La valutazione finale mira a definire per ogni studente i risultati di apprendimento attesi. Nello specifico la valutazione finale consta di un esame scritto e di una parte orale facoltativa. Non sono previste prove in itinere. La prova scritta ha l'obiettivo di valutare la conoscenza di base della materia e riguarderà tutti gli argomenti trattati a lezione/esercitazione durante lo svolgimento dell'insegnamento. A discrezione del docente (se cioè non risultasse evidente l’effettiva preparazione dello studente oppure se si evidenziassero specifiche lacune), oppure qualora ne faccia esplicita richiesta lo studente (se cioè lo studente ritenesse la sua preparazione migliore di quanto il voto proposto in fase di valutazione finale non rappresenti), è prevista anche una parte della valutazione finale da svolgersi oralmente con domande aperte sugli argomenti del programma

The exam is aimed to assess: Knowledge and understanding Ability to apply knowledge and understanding Autonomy of judgement (in case of oral exam) Communication skills Learning ability (in case of oral presentation) Written exam (mandatory) Via this exam, it will be possible to test students’ acquired knowledge and understanding and the application of acquired knowledge and understanding. The written exam consists of a set of questions to answer (in order to check knowledge and understanding) and quantitative problems to be solved (in order to check application abilities); their assessment equally takes into account the formal development and the quantitative/qualitative content, so as to appraise the capability of each student to: identify the relevance of either contextual factors, or functions or processes with respect to the performance of a project, or of a plant as a whole, or of a single component; set up and solve a problem related to a project, or to plant as a whole, or to a component. The exam is an individual test developed through three sections: multiple choice theoretical questions: the student must answer correctly at least 66% of them in order to go on with the exam (otherwise he/she gets a fail-mark), open-ended theoretical question(s), numerical problems (at least two exercises for Industrial Plants A and one for Industrial Plants). Oral exam (based on the result of the written exam) Via this exam, it will be possible to fine tune the mark taken in the written exam. The decision about the oral exam is up to the professor only, based on the result of the written exam. Oral presentation Via this elective activity, it will be possible to submit an individual or group (up to three students) elective project work about one of the topics of the course (given by the professor), so to contribute to the final grading. Final Grading To pass the course, students must get a pass mark given by the written exam, eventually integrated with an oral exam (based on a decision by the professor), and the additional points (up to 2/30) of the oral presentation (elective project work).

Modalità d'esame
Progetto/i - Elaborato/i obbligatorio, di gruppo, con revisioni periodiche, con presentazione/discussione finale Students will pass the course after completing an oral presentation and discussing the report written on the assigned project. As a crucial part of the course, students, grouped in teams, will be tasked with a design problem. This could involve developing a new product or enhancing an existing one. The problem must be approached using the methods and techniques learned. The team is expected to create a comprehensive report detailing their solution process and the outcome. They will also need to present their work and results orally. The final grade will be determined based on the written report and the oral presentation, underlining the significance of this project in the course. The design project intends to check if the students have the following abilities: to detect the functionality of an industrial product and its sub-assemblies; to apply systematic methods to solve a design problem; to collect the information required to develop a design solution; to arrange an abstract solution into a complete embodiment design for a product; to select, also in a critical manner, the more helpful method to face the problem posed; to communicate own results in agreement with the technical communication languages adopted in the mechanical engineering field. Students who do not attend or participate in the design project will be evaluated based on a written test followed by an oral discussion. This test will be focused on a specific and confined design problem. Using these tests and discussions, you intend to validate the abilities acquired by the student: to analyse, using a systematic approach, the problem posed and identify the main functionalities of the system proposed; to arrange and collect the information required to solve the problem using one of the methods learned; to apply an evaluation criterion to select the best solution between those discovered; to describe the embodiment architecture of the final solution; to communicate the result obtained.

The increasing computer power is nowadays essential to deal with the numerical solution of large dimensional problems, however a computational reduction is still determinant whenever interested in real-time simulations and/or repeated output evaluations for different values of some inputs of interest. In order to reduce this computational burden, we may rely on suitable reduced order models (ROMs), which are faster and cheaper to simulate, yet accurately represent the original high-fidelity (or full-order) system behavior. Within this class of techniques, parametric model reduction has emerged only in the last decade as a very active research area. Parametric ROMs target the broad class of problems for which the equations governing the system behavior depend on a set of parameters, such as in the case of parameterized PDEs. These parameters may represent, for instance, material properties, system geometry, boundary or initial conditions. The goal of parametric ROMs is thus to generate rapid but reliable models that characterize the system’s response over the whole parametric range. Such a strategy proves to be necessary in order to speedup design, control, optimization, and uncertainty quantification settings, usually requiring several repeated model evaluations. This course surveys the state-of-the-art of parametric reduced order models, describing the most popular approaches related to physics-driven techniques (such as reduced basis methods and proper orthogonal decomposition) and data-driven techniques (such as non intrusive ROMs based on interpolation, surrogate models involving, e.g., neural networks, and model discovery techniques), providing also a comparative discussion that lend insights to potential advantages/disadvantages entailed by their application.
Besides the knowledge of theoretical results and numerical methods presented during lectures and Lab sessions, a critical comprehension of the class’ topics is expected by the students at the end of the class, justifying the followed procedures. Attending the course, students are expected to: know and understand how to perform numerical simulation of problems of interest in mechanical engineering (e.g., heat and mass transfer, linear and nonlinear elasticity/elastodynamics, fluid dynamics) in many-query contexts (e.g., repeated simulations in multiple scenarios; control and optimization) or real-time contexts (e.g., predictive digital twins); set, analyze and apply reduced order modeling techniques for differential problems built on top of classical numerical methods (e.g., finite element method), of both physics-driven and data-driven type; exploit already acquired numerical methods in Engineering to set up physics-based ROMs (e.g., reduced basis methods); exploit recent strategies in scientific machine learning for the efficient numerical simulation of physical systems through data-driven ROMs (including, e.g., simple neural networks); adapt the proposed methodologies to more general problems of applied interest in Engineering; interpret the results, assessing both accuracy and efficiency of simulation strategies, from both a numerical and a statistical point of view.
Programma
The course is organized in a series of lectures and practical lab sessions. Lectures will provide the theoretical background; practical Lab sessions will provide algorithms' implementation and examples of application of the considered methodologies by using basic (e.g., Matlab or Python) codes. After reviewing basic concepts in numerical methods for differential problems, the course will focus on the following topics: Dimensionality reduction algorithms Singular value decomposition, optimal low-rank approximations, proper orthogonal decomposition. Autoencoders. Projection-based reduced order modeling techniques The reduced basis method for (linear) parametrized partial differential equations: reduced space construction, (Petrov-)Galerkin projection, a posteriori error estimation. Affine parameter dependence. Hyper-reduction techniques Extension of the reduced basis method to nonlinear and/or nonaffinely parametrized problems. Empirical interpolation method. Non-intrusive reduced order modeling techniques POD with interpolation (e.g., Neural Networks, Gaussian Process) strategies. Autoencoders and basic ideas on deep-learning reduced order models for parametrized systems. Data-driven dynamical systems Dynamic mode decomposition. Sparse identification of nonlinear dynamics (SINDy). Neural ODEs. Model discovery techniques for the latent dynamics. Physics-informed machine learning SINDy Autoencoders: extension of SINDy to high-dimensional systems. Shallow recurrent decoder networks for reduced order models embedding sensor data. Learning nonlinear operators (e.g., deep operator networks).
Modalità d'esame
Prova orale obbligatoria The oral exam covers the content of both theoretical lectures and practical Lab sessions. During the exam, students are required to present the detailed solution of two selected assignments (among a list of assignments proposed during the practical Lab sessions), commenting both the numerical results obtained and the computational procedures employed, and to answer to theoretical questions related with the topics of the course. Assignments will require students to apply, adapt, or extend some of the methods presented during the course to selected practical case studies. The assignments will be evaluated during the oral examination and must be submitted to the examiners by the deadline communicated during the classes. Theoretical questions will assess students' knowledge of the methodologies covered throughout the course. During the examination, students will first be required to sketch written answers to the theoretical questions, before presenting and discussing them with the examiners. The course will be based on a selection of chapters of the following books, class notes, and some selected scientific papers provided:

The course fits into the overall program curriculum and in particular it contributes to the development of the following capabilities: Understand context, functions, processes in a business and industrial environment under the life cycle thinking perspective, and the impact of those factors on business performance towards the entire product life cycle Identify trends, technologies and key methodologies in the domain of product life cycle management, within a pletora of different application contexts such as industrial design and engineering, mechanics and automation, fashion and food industry Design solutions applying a scientific and engineering approach (Analysis, Learning, Reasoning, and Modeling capability deriving from a solid and rigorous multidisciplinary background) to face problems and opportunities in business and industrial environments The aim of the course is to introduce students to the basic concepts of Product Lifecycle Management (PLM) and Life Cycle Thinking. The acronym PLM enables a holistic life cycle-oriented way of thinking through a set of principles, methods and tools supporting a more effective and efficient management of the life cycle stages of industrial products and systems, from their design/engineering, to production, distribution, usage until disposal/end of life. In its comprehensive meaning, PLM is a business approach based on collaboration and integration of people, processes and technologies, which aims to support the development of more innovative, reliable and sustainable solutions (products and services) in a shorter time. From a managerial perspective PLM encompass (i) a strategic management point of view where the product is the enterprise value creator; (ii) the application of a collaborative model for the empowerment of the core competences distributed along the different actors involved in the lifecycle (e.g. designers, engineers, manufacturers, suppliers, etc.); (iii) the adoption of a number of IT solutions for establishing an access-safe product information management environment. From a technical perspective, PLM is a matter of methods, standards and techniques for structuring the engineering processes, as well as a matter of computer-based tools for enabling virtual prototyping and collaborative workspaces. In this context, Lean Product and Process Development is a paramount support for the effective understanding and accomplishment of the above mentioned points and will play an important role, not only as topic of discussion taught within the course, but also used to generate within the students critical attitude towards problem understanding, problem setting and problem solving. The aim of the PLM course is to introduce students to the concepts and elements of PLM, life cycle thinking and lean product and process development, from both managerial and a technical perspective, giving also the basics to run the introduction of PLM (as approach, models, methods, and tools) in the industrial practice, approach problems and process improvement via lean thinking, with the ultimate purpose to grow a life cycle thinking attitude into the students.
Expected results from Product Life Cycle Management Class are: Understand - provide students with the prevalent knowledge in the field of PLM and Life Cycle Thinking from a theoretical and practical side to show how these aspects reflects on real business. The students are expected to gain general knowledge on PLM, life cycle thinking and all related topics. Identify - students, will gain general knowledge needed to understand PLM, and will be provided with specific knowledge on trends and approaches existing in effective and advanced PLM impelmentation solutions from industry, such as lean product and process development. Students will be expected to be able to identify how specific approaches enable and impact life cycle thinking within enterprises. In the specific lean product and process development as a overall and growing body of knwoledge will be taught to the class that is expected to acquire deep knowledge on that. Design - most importantly, students will be provided with the ability to aquire and develop a critical thinking attitude in business process understanding and problem solving. This will be achieved through a continuous link between in class theoretical applications and real world applications, as well as challenges proposed to students to be addressed in class via exercises, serious games, projects and teamwork activities. The ultimate purpose is to make this class not as the arrival learning point for these concepts, but to be the starting platform to build and link what has already been learned and what needs to be learned in the future to address growing buiness needs-by applying either what has been introduced in this course or learnt soemwherelse- enable a relentless life cycle thinking mindest.

Reverse Engineering (RE) is a multidisciplinary scientific method that can be applied to several different fields. Although in broad sense the term Reverse Engineering is used in many different areas (e.g., from software code development for decode the mechanism of a function, to Internet network security), the version of the concept considered in this course is the digital reconstruction of a physical object or environment, starting from a set of 3D data captured in the real world. The course aims at illustrating the operating principle of the various 3D sensors currently available on the market, framing them in a general context, specifying their functions and motivating their performance. A substantial practical laboratory activity is planned, during which the students, through individual or group exercises, develop digital 3D models of real objects both with active and passive techniques.
After passing the exam, the student: knows the theoretical principles of 3D measurement; knows the basic terms and principles of active and passive sensor measurement technologies; knows the characteristics of the principal instruments usable for a 3D survey; Knows the process workflow to go from a real object to a digital 3D model; Is able to analyse an object or scene to survey and identify the most appropriate measurement system; Is able to determine in advance the problems of a survey and adopt the appropriate solutions; Is able to characterize or calibrate an instrument; Is able to select and execute the working pipeline to obtain a result appropriate to the requirements of the specific work (for example accuracy, resolution, number of model polygons); Is able to motivate its design choices and communicate the results of its activities in a clear and convincing way.

This course aims at introducing the main concepts related of rotor dynamics and diagnostics. Rotor dynamics is the key for the design and operation of many machines: turbine of any kind used for power generation, aircraft engines, electrical motors, centrifugal compressors, etc. Thus, the dynamics of the complete machine and of its main components, like shafts, bearings, seals and blades is presented in detail. Several design tools and examples are introduced. Diagnostics is an emerging requirement in modern mechanical systems in order to shorten out-of-service and reduce operation costs. Very often, the faults are affecting the same components analysed by rotor dynamics and this makes the two parts of the course strictly connected. State-of-the-art techniques, based on both system model and data analysis, are introduced. All the topics are analysed under practical and theoretical points of view, with several examples of application in real machines, of design cases and of case histories. The seminars, conducted by industry experts, are essential parts of the course. A visit in a factory of a major OEM in rotordynamics sector is scheduled during the course.

Modalità d'esame
Prova orale obbligatoria Organization of the course and methods of verification The course is divided into a series of lessons and practical exercises, related to the topics of the lessons, aimed at consolidating the knowledge and methods learnt during the lessons. The exam consists of an oral exam. The oral exam consists in answering questions, in open form, that focus on all the topics covered in the course, accompanying the answering with equations, graphs, sketches, in a synthetic and complete exposition. Depending on specific logistics problems, it could be required to perform the oral exam by answering the questions by composing a written document, which will be discussed with the teacher. The purpose of the oral test is to verify the knowledge underlying the study of rotordynamics and diagnostics, and the applications covered in the course, evaluating both the understanding of physical phenomena and their mathematical implementation (demonstration). The oral test also verifies the ability to transmit the results of the analyses carried out both in mathematical terms and with graphic representations. Slides of the lessons, which include all the topics of the course, are provided via BeeP. The bibliography is suggested and can be fruitful consulted for individual in-depth analysis. Final Grading To pass the course, students must successfully pass the oral exam

Obiettivi formativi
The course is aimed at providing the students with sufficient background to allow their efficient interaction with naval engineers in the definition of inputs and the assessment of the outputs for structural analysis and design of a ship. To this aim, the following objectives are pursued:
untroduce students with generic background (mainly mechanical engineers) to the field of ship structural design and analysis; to this aim, the first part of the course is devoted to the general definitions and illustration of structural components of a generic steel ship;
provide students with theoretical concepts and practical instruments for design and analysis of ship structures;
provide students with practical examples of application, referring to realistic case studies;
illustrate the most common problems affecting ship operation, from structural point of view, and new trends toward operation and maintenance optimization.
At the end of the course, students will have acquired the content and exercise practices as established in the learning objectives. In terms of knowledge and understanding, students will be able to:
identify the most common loads acting on the ship structure and determining the stresses for ship design and verification

calculate stresses and perform structural analysis and assessment of primary ship elements (including joints)
apply the theoretical aspects to realistic use cases, based on Finite Element Simulation The active participation of students in the proposed teaching activities is encouraged through the use of an interactive teaching method based on a combination of lectures and practical group activities. In particular, these exercises aim to directly involve the students and analyze real-world issues from a firsthand perspective. Critical team discussions primarily facilitate the acquisition and subsequent enhancement of problem-solving skills and independent judgment. The following phases will be addressed during the practical activity, under the guidance of the instructor: 1. problem definition and active discussion in macro-groups; 2. generation of alternatives: Students, typically exposed to lectures and closed problems, are invited to develop creative solutions to the given question; 3. evaluation of alternatives: The ability to select, separate, and reorganize emerging design choices is stimulated; 4. practical implementation of theoretical solutions and possible presentation of the obtained results. Finally, the students will have improved their communication skills, specifically their ability to correctly formulate design problems and/or structural verification using appropriate technical language combined with proficiency in the necessary methodologies for their solution. The use of specific terminology is enhanced both during the learning phase in the exercises and during the evaluation phase in the completion of written and oral exams and/or the potential presentation related to the laboratory activity.
Programma
The course covers the following topics:
Design of joints (welded and bolted connections)
Buckling analysis of pillars
Analytical description of plate bending elastic problem
Unstiffened and stiffened plate buckling
Fatigue of weldings
Operation and maintenance of ships (current and new trends) The theoretical aspects introduced in the course will be correlated with practices and laboratories, for a direct implementation of the methods. Specific laboratory experiences will be dedicated to the application of Finite Element theory for static linear and nonlinear (buckling) analysis with emphasis on result post-processing, their critical analysis and presentation.
Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere Progetto/i - Elaborato/i obbligatorio, individuale, senza revisioni periodiche, senza presentazione/discussione finale The final exam will consist of a written examination and the delivery of a report on a limited number of practices. The written exam will include theoretical questions and possibility to solve simple exercises. The report will be assessed based on a 0-8 points scale, and will concurr to the final grade.

The capability to conceive and generate digital representations of their products and projects is an essential skill for engineers. As the design and manufacturing technologies advance, the shape of the products evolves as well, becoming more and more complex. This course aims at giving students the ability to make 3D models of complex shapes through surface modeling approaches and understand the role of this technology in different phases of the product development process. The course will present an introduction to 3D surface modeling techniques and their applications in Engineering. The mathematical foundation of parametric curves and surfaces (splines, Bezier, NURBS) will be briefly presented. Beyond the theory, the course will adopt a hands-on approach by allowing students to practice with modern computer-aided design tools. Different 3D models of both aesthetic surfaces and technical surfaces (e.g. ship hull, airfoils, blades, etc.) will be made and discussed. Finally, the capability to prepare those models for numerical analysis will be also discussed.
Upon completion of the course, students will be able to: understand the theoretical foundations of CAD tools and 3D surface modeling techniques, and explain the role of surface modeling in the product development process; create complex 3D models using surface modeling techniques and develop suitable modeling strategies for different engineering applications; assess the suitability of 3D models for specific applications, including numerical analysis; communicate design choices, modeling strategies, and project results effectively through technical presentations and discussions.
Programma
The course covers the following topics:
Introduction to surface modeling: the role in the product development process and comparison with solid modeling.
Mathematical foundation of parametric curves and surfaces. The Bézier, Spline, Coons and NURBS both in their rational and non-rational forms will be introduced. The concept of geometric continuity will be discussed.
Surface modeling approaches: Freeform, patch and subdivision surface.
Algorithmic and generative approaches to surface generation.
Reverse Engineering: from point clouds/meshes to surface models.
Implications of surface topology and geometry for numerical analysis and mesh preparation.
Strategies to approach the modeling of complex objects with applications and examples to specific domains, such as p roduct design, marine, wind, automotive and manufacturing. The course contents will be delivered through lectures and laboratory activities using a 3D modeling software.
Modalità d'esame
Prova scritta obbligatoria, con prove in itinere Progetto/i - Elaborato/i obbligatorio, di gruppo, senza revisioni periodiche, con presentazione/discussione finale Students will be evaluated through both an individual test and a project assignment, designed to assess their understanding of the course topics and their ability to apply the acquired skills in practice. The individual test is a multiple-choice test and accounts for 30% of the final grade. The project assignment accounts for 70% of the final grade. The topic of the project is free, but some proposals will be presented during the last month of the course. The project evaluation will be based on the project material, including 3D models, and the quality of the presentation. Generally, the project will be carried out in groups, but individual projects will also be allowed.

Il corso, a partire dalla descrizione di alcuni sistemi di trasmissione significativi e dei relativi componenti, mette in evi-denza l'importanza della corretta scelta e applicazione degli elementi di macchine. In una prima fase del corso vengono pertanto presentati, o approfonditi nel caso di elementi già introdotti in insegna-menti precedenti, gli elementi di macchine fondamentali quali i collegamenti filettati, con perni e spine, molle, cuscinetti a rotolamento e lisci, assi, alberi e calettamenti. Di questi verranno descritti in modo sistematico la morfologia, le di-verse soluzioni costruttive, il progetto, l'applicazione, le tolleranze e il calcolo di verifica rispetto ai principali cedimenti. Successivamente saranno presentati gli ingranaggi cilindrici, con i necessari richiami di geometria e cinematica, e i principali cedimenti quali la fatica al piede, il pitting, il micropitting, lo scuffing e l'usura. Infine saranno considerati alcuni sistemi di trasmissione, sia ordinari che epicicloidali, mediante i quali gli allievi si confronteranno con lo studio dei flussi di potenza, degli equilibri di forze e momenti, delle perdite e dell'efficienza. Esercitazioni e laboratori di progetto saranno l'occasione per applicare i principi teorici a casi pratici. Completano il corso una visita tecnica presso il centro di ricerca FZG della Technische Universität München e presso un'azienda da definire.

Programma
Today’s world, where speed is gaining increasing relevance to make innovation happen, has called for the emergence of approaches that leverage continuous testing and iteration. After the introduction of the Agile Manifesto in 2001, a wide range of industries has experienced the massive diffusion of Agile approaches. These approaches leverage agility, flexibility, and the rapid development of new solutions. On the one hand, Agile emerges as a tool to change the development process; on the other, it emerges as a culture to embrace flexibility. Especially this cultural aspect is crucial in agile innovation approaches, to face emerging issues and have an impact on companies solutions. Design is recognized as a powerful approach to reduce uncertainty; more specifically several studies show that adopting a design mindset can help embracing ambiguity and foster innovation even when the problems are wicked and ill-defined. In discovering new technologies, knowledge and uncertainty are always high, and the search for the right application might require different and complex iteration and experimentation processes. Design Sprint represents a new approach deeply rooted on agile culture, design attitude and experimentation mindset. It aims at accelerating innovation by the adoption of sketching, testing and prototyping tools. The course has been designed around the following main topics: Agile Culture: Making innovation happen in a continuously changing environment where ambiguity, variability and complexity is raising requires new mindset and approaches. Thus, agile innovation is gaining traction as a culture to cope with these shortcomings, in promoting both a agile culture and tools to make innovation happen. Furthermore, lean development and lean startup are approaches that are getting more and more relevance in today’s panorama not only in hi-tech industries. Agile methodologies and specific approaches such as SCRUM are fundamental to properly manage innovation projects in turbulent environments; Design Attitude: The emergence of new paradigms such as human-centered design, participatory design and design thinking, have marked the transforming role of design in the field of innovation management. Design is not only an aesthetic driver of innovation but represents a new set of innovation management practices. It is something practiced not only by designers but by everyone in organizations who seeks to innovate; Experimentation Mindset: Innovation approaches, such as agile development, and lean startup, may differ on some principles and practices, but they have one key ingredient in common: experimentation. Recent approaches leverage experiments for exploratory learning. In particular, “quick & dirty” prototypes are used to search the most valuable innovation opportunities. The changing nature of experimentation in innovation is supported by the digitalization trend. The increasingly digital nature of products and services facilitates early, less expensive, higher-fidelity prototypes and the subsequent tests.

This course is of 6 CFU and is associated with a version of 5 CFU named 097688 - ECONOMICS AND COMPUTATION (5 CFU). The current form specifies goals, program and expected learning results for both courses. For both versions of the course (6 CFU and 5 CFU), the goal of the course is to provide the groundings of algorithmic microeconomics. More precisely, the course explores mathematical models, computational complexity, and algorithms for economic settings. The course focuses both on non-cooperative game theory, describing the models and the algorithms used in real-world applications in various settings (e.g., poker and security), and on mechanism design, describing economic mechanisms and algorithms used in auctioning settings (e.g., digital advertising and online auctions). The treatment of the topics will be both from a theoretical point of view, describing the models/algorithms and their properties, and from a practical point of view, discussing how the algorithms can be applied and applying them in practice during some laboratory sessions. Furthermore, the course aims at presenting some real-world applications of paramount importance. The difference between the two versions of the course (6 CFU and 5 CFU) is just in the depth with which some topics are discussed.
For both versions of the course (6 CFU and 5 CFU), we expect that the students learn: how to model real-world applications by means of mathematical models from microeconomics, how to identify the most suitable class of algorithms to solve a given problem, how to use the tools already available to solve a given problem in practice, how to design an algorithm to solve a given problem whenever no algorithm is known

More precisely, the exam can be of two forms: standard: written exam (2.5 hours) 3 exercises (the first exercise is on noncooperative game theory models and on the adoption of operations research tools to solve a game, the second exercise is on algorithmic game theory or economic mechanism design, the third exercise is on economic mechanism design or algorithmic mechanism design) (max 27 points), --- here the students are required to solve exercises similar to those studied during the course or to answer some theoretical questions about topics discussed during the course; the capabilities the students must show are: modeling real-world applications by means of mathematical models from microeconomics, indentifying the most suitable class of algorithms to solve a given problem, using the tools already available to solve a given problem in practice ---; 1 question on advanced topics (on all the topics of the course) (max 5 points) --- here the students are required to answer a question that is beyond the topics discussed during the course; the capabilities the students must show are: generalizing the skills learned during the course to design an algorithm for a given problem that has not discussed during the course; engaged: the course is divided into four parts (Part 1: noncooperative game theory models; Part 2: Maxmin and Nash equilibrium; Part 3: Stackelberg, Congestion games, social choice functions; Part 4: mechanism design and algorithm mechanism design), at the fourth week of each part of the course, students take part in a midterm exam (2.5 hours), composed as: exercise/theory (1 exercise and 2 theory questions) (max 27 points) --- here the students are required to solve exercises similar to those studied during the course or to answer some theoretical questions about topics discussed during the course; the capabilities the students must show are: modeling real-world applications by means of mathematical models from microeconomics, identifying the most suitable class of algorithms to solve a given problem, using the tools already available to solve a given problem in practice ---; challenge on scientific research problems (max 8 points); the challenge is carried on by teams, each of 2-3 students --- here the students are required to answer some questions that are beyond the topics discussed during the course; the capabilities the students must show are: generalizing the skills learned during the course to design an algorithm for a given problem that has not discussed during the course. Each student can choose the form of the exam she/he prefers. If a student opts for the engaged form and she/he is not satisfied with the achieved grade, she/he can repeat the exam in the standard form.

L'insegnamento ha come obiettivo quello di introdurre, con una visione sistemica, lo studente alle problematiche della guida autonoma al fine di renderlo consapevole delle sfide tecnologiche che tale rivoluzione sta ponendo. In particolare, a valle di una panoramica sull'evoluzione dei sistemi ADAS che hanno portato, come naturale evoluzione, ai veicoli autonomi, il corso si articolerà in tre parti: la sensoristica necessaria alla guida autonoma, gli approcci controllistici e le sfide aperte, l'interazione del veicolo con l'ambiente circostante. Oltre alla parte di didattica frontale, grazie ai prototipi di veicoli autonomo sviluppati negli anni, lo studente avrà la possibilità di verificare praticamente gli aspetti principali del corso. Sono previsti interventi di esperti sia accademici che industriali del settore e, laddove possibile, visite guidate.

Autonomous vehicles and mobile robots require the integration of modelling, perception, planning, control, decision-making and software implementation. The course introduces the main theoretical and practical tools needed to understand and prototype autonomous vehicular and mobile robotic systems. The course follows a modular autonomy-stack perspective, with emphasis on the see-think-act paradigm. After an introduction to autonomous and connected vehicles and mobile robots, the course covers vehicle and mobile-robot modelling, trajectory planning and tracking, motion planning, vehicular sensors, basic computer vision, localization and mapping, and decision logic. A short overview will also be provided on how data-driven approaches can complement classical model-based methods in autonomous systems, for example in perception, prediction, decision support, model residual learning and learning-augmented control architectures.
Lectures, exercise sessions and project activities will allow students to: understand the main components of the autonomy stack for autonomous vehicles and mobile robots, including modelling, perception, planning, control and decision logic; model simple nonholonomic vehicular and mobile robotic systems and design basic trajectory planning, tracking and closed-loop control algorithms; formulate and solve motion planning problems using graph-search and sampling-based methods; understand the role of common vehicular and mobile robotic sensors, apply basic perception techniques, and interpret the use of data-driven methods as a complement to model-based pipelines; critically analyze implementation choices, experimental results and system limitations, and communicate them through reports and project discussions

The goal of the course is to enable students to understand and be familiar with model-based and simulation-based approaches to statistics. In particular, the course focuses on Bayesian learning, its tools and main classes of models. This will enhance students’ abilities to address the statistical analysis of complex systems for which transversal and multidisciplinary skills are required. The Bayesian approach tells us how to update prior beliefs about parameters and hypotheses of a probabilistic model in the light of data, to yield posterior beliefs. In particular, Bayes' Theorem quantifies the problem of how to learn from data. Bayesian learning hinges on simulation methods, typically MCMC algorithms, to compute the posterior distribution. The course adopts innovative teaching methods: a data analysis project, as a part of the student assessment, to enhance specific soft skills such as Making judgements, Communication skills and Ability in learning ( 3 rd, 4 th and 5 th elements of the so-called European “Dublin Descriptors” – DD ) collaborative activities among students, some in small groups, and with continuous assessment of learning. This type of activity is in presence. This is a 10 ECTS course, course code # 052499. However, there is a version of it (code # 052502, Bayesian Statistics, 8 ECTS). The only difference between the two courses is that the topics of the 8-credits course do not include neither topic 6 nor models for areal and point-referenced data in topic 7 (see the list of topics below). For the LM program in Mechanical Engineering, there is a 5 ECTS course in Bayesian Statistics. In this case, the topics are only 1-4 from the list below.
On successful completion of the course, students will be able to: understand the fundamental principles, tools and models of Bayesian Statistics (DD 1 - knowledge and understanding ) model simple engineering problems in terms of statistical problems using the Bayesian approach to update prior belief in the light of new data (DD 2 - Ability in applying knowledge and understanding ) select appropriate Bayesian tools to give statistical answers and use appropriate software ( R packages, JAGS, Stan, Python) for the computation of posterior inference, or to build this software by themselves (DD 2) operate and communicate the choices made, making independent judgments, when using Bayesian tools for dealing with statistical problems from the real world (DD 3, 4 and 5) work effectively as part of a team.
Programma
The first part of the course (topic 1) will enable students to understand foundational aspects of Bayesian Statistics (the choice of the prior, for instance), while in the second part (topics 2-7), after the introduction of Markov Chain Monte Carlo techniques for simulation from the posterior, students will be able to use specific statistical models for estimation, prediction or clustering. 1. Basics of Bayesian inference. Likelihood principle, prior and posterior distribution. Bayes' Theorem for dominated models. Posterior summary values. Interpretation of scientific inference via the Bayesian approach. Simple univariate Bayesian models. The three main inferential problem: point estimation, hypothesis testing, interval estimation: comparison between the frequentist and the Bayesian approach. Prior distributions. The choice of a prior distribution, noninformative priors, conjugate priors and their mixtures, semi-conjugate priors. Robustness. Exchangeability and de Finetti's representation theorem for exchangeable sequences. Implications of de Finetti's theorem on the Bayesian approach. Predictive inference. Asymptotic results on the posterior distribution. 2. Simulation methods for Bayesian Statistics. A quick recap on the theory on general state space Markov chains. Markov chain Monte Carlo methods. Gibbs sampler and Metropolis-Hastings algorithms for computing posterior inference. Implementing Markov chain Monte Carlo: software for Markov chain Monte Carlo (BUGS/JAGS from R), assessing convergence and run-length. 3. Goodness-of-fit and model choice. AIC, BIC, DIC, Predictive Bayesian tail probabilities, log-pseudo marginal likelihood (LPML), WAIC; prior and posterior distributions for the model index, maximum a posteriori (MAP) model selection. 4. Bayesian linear models and generalized linear models. Hierarchical linear models with random effects. Parameter estimation and covariate selection. 5. Bayesian survival analysis / reliability with censored data. Regression models: accelerated failure time and proportional hazards models. 6. Bayesian nonparametric models. The Dirichlet process and generalizations. Bayesian nonparametric mixture models, with application to density estimation and clustering. 7. Introduction to models for longitudinal data, time series, spatial data (point-referenced and areal data). Within the Innovative teaching activity, we include 2 classes (4h + 4 h) in presence, during which students will be required to do exercises for designing and implementing (using Python or R software) algorithms for simulation, supervised by tutors and the teaching assistant. This type of active learning will include continuous assessment of learning. The oral exam consists in the presentation of the project (in groups), focusing on a statistical problem with data, using Bayesian models, to enhance students’ soft skills such as Making judgements, Communication skills and Ability in learning. There will be intermediate revisions of the projects (this is a group activity), where the groups will discuss with tutors, TA and instructors, in presence. This type of active learning will include continuous assessment of learning. The list of topics for the course with code # 052502, 8 ECTS, do not include topic 6 nor models for areal and point-referenced data in topic 7.
Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere Progetto/i - Elaborato/i obbligatorio, di gruppo, con revisioni periodiche, con presentazione/discussione finale The exam consists of two parts: a written exam and a project work (with a final oral presentation). It is compulsory to register for the written exam, which is scheduled twice in January-February, twice in June-July, and one in September. The final project assessment is the presentation of the work on project, i.e. analyzing a statistical problem with data, using Bayesian tools and models. The projects will be developed in teams. The evaluation of the projects will be based on the revisions (activity in presence - at most two) the teams will undergo during the course and a conclusive presentation. During the conclusive presentation, each students’ team must hand over a project report (10-20 pages). Participation in presence to the revisions and the final presentation is compulsory for all team members, but for Erasmus students. If, at the beginning of the semester, the student understands he will not be able to actively participate in the group project during the semester for any reason, the student is allowed to discuss an individual project after passing the written test, instead of the group project. Because the student will not be tested on all the Expected Learning Outcomes (Risultati di apprendimento attesi), the final grading of the individual project cannot be larger than 26/30. To obtain a positive final mark, the student should pass with a grade greater or equal than 18/30 for both parts of the exam. Final grading: 40% written exam, 60% project work. After the exam: the student will know the fundamental principles, tools and models of Bayesian Statistics (DD1), he/she will be able to apply the acquired knowledge to statistical problems from the real world (DD2), making independent judgments, the student will operate and communicate the choices made, when using Bayesian tools to solve statistical problems from the real world (DD3,DD4,DD5).

Goals The objective of the course is to present to the students, approaching the end of their M.Sc. educational carrier, an overview of the field of biochips and analytical lab-on-chip microsystems (whose recent advances are relevant both from the scientific and industrial point of view) with specific insights on the technological aspects of the interface between (micro)electronics and electrochemistry and biology, both at cellular and molecular levels. The content of the course reflects the multidisciplinarity of the nano-bio-tech field and is mainly focused on the different manipulation and detection approaches of biochemical target analytes on chip. The main goal is to provide the students with the fundamental theoretical tools for the design of active microfluidic systems (basics of fluid dynamics at the microscale), and of the engineering of the detection systems (optical and electrochemical transducers). At the same time, several practical examples are discussed in order to illustrate design choices and trade-offs. Starting from 2020, a part of the course will be taught by means of innovative learning techniques. The topics of microfabrication (hard and soft-lithography) will be addressed by means of MOOC videos recorded in actual clean-rooms and fabrication facilities. Finally, a "blended" and "flipped-classroom" approach will be adopted in the last part of the course including a project-based and a laboratory activities where student will fabricate real devices and boards: at first they will be grouped into small teams (3-4 persons max.), will design at home the layout of the microchannels and electrodes on a PCB including a transimpedance amplifiers, according to some design challenges posed by the teacher, and then will fabricate them in the lab with 3D printing and soft-lithography (PDMS elastomer by means of replica molding). A characterization with fluids, electrolytes. digital microscopes, pumps and virtual instrumentation (oscilloscope, network analyzer used for impedance measurements) will conclude this experimental activity. Prior to fabrication of the PCB, each team will present their design in the class and feedback from a general discussion will be collected.

The exam consists of a written test (of a duration of 2 hours) followed by an oral exam. The written test (assessing Dublin Descriptors 1 and 2) encompasses the solution of numerical exercises focusing on 2 types. The first type concerns the microfabrication and the fluidics (and components) of micro-channels and devices. The second type mostly focuses on electrochemical detection. The students will be asked to analyze circuits and systems, as well as to design them. The maximum evaluation of the written test is 30. Two bonus points are added for those who attended the laboratory activity. The outcome of the written tests is communicated to the students by email. Then, a meeting in the classroom is scheduled for the students to vision and discuss the correction of the written test. They can accept or refuse the evaluation, either by email or in-person communication. They can undertake the oral test in the following days, by agreeing a calendar with the teacher. The oral discussion (assessing Dublin Descriptors 1,2,3,4) is mandatory for students achieving top marks in the ranking (> 27/30) in the written test and it is optional and open for all students with a mark above 17/30 in the written test. In the oral test (lasting 15 to 40 minutes) students will be asked discuss the ultimate limits of the different technologies, pros and cons, compare them, and to design complete systems to address novel design cases proposed during the oral exam. The maximum evaluation is 30 cum laude.

Obiettivi formativi
This course aims to equip students with the tools necessary to identify, understand, analyze, and integrate bio-inspired solutions for engineering problems related to the structural design of mechanical components. By investigating several examples of bio-inspired engineering solutions, the course will emphasize how to extract corresponding structural design principles and fundamental mechanisms. Significant attention will be paid to mechanical properties, mechanical design, and manufacturing approaches, essential for exploring these bio-inspired solutions. The specific objectives of the course are: To provide the ability to identify biomimetic structural design principles. To explore the critical inspiring aspects in various structural categories and how they have been implemented in bio-inspired structural design. To analyze how the principles of structural design and manufacturing tools can be used to implement bio-inspired solutions to tackle challenging structural problems.
At the end of the course, students are expected to have developed skills and competencies as established in the training objectives. In terms of knowledge and understanding, students will be able to: Describe the principles of classic bioinspired structural designs. Categorize bioinspired structural solutions based on their main source of inspiration, considering the three major classes: shape and morphology, structure and architecture, and surface features and texture. Identify the fundamental biomimetic structural design concepts and the working principles for each main category. Interpret and discuss the related materials-structure–property relationships for the categories covered during the course. Analyze the implementation of such bioinspired structural principles from an engineering perspective. Active participation in the proposed teaching activities is encouraged through an interactive teaching method, which combines lectures and practical group activities. These exercises aim to directly involve students in the definition, design, analysis, and implementation of bioinspired structural solutions, primarily through team projects developed during the exercise sessions. Brainstorming and critical discussions in teams will enhance and strengthen students' ability to identify and explore natural structural design strategies and develop innovative solutions. These activities will also help students develop problem-solving skills, improve teamwork abilities, and enhance presentation and communication skills. The following phases will be addressed during the exercise sessions: Identification of architectural elements and geometrical aspects in natural systems that contribute to their advanced mechanical performance. Definition of structural design concepts for the creative generation of periodic lattice structures inspired by the identified geometrical and structural features. Evaluation of the structural integrity of the designed lattice structures through finite element analysis and possible experimental tests. Practical implementation of theoretical solutions, report preparation, and presentation of the obtained results in the corresponding project.
Programma
The teaching activities are conducted through lectures and exercise sessions. The lectures cover topics that explore architecture, shape, and surface inspiration for enhanced structural performance, as briefly described below: Introduction to Bioinspired Structural Design Methodology in Bioinspired Structural Design Structure and Architecture as Inspiration Architected Lattice Structures Heterogeneous Structures Functions and Bioinspired Applications of Gradients Kirigami- and Origami-Based Bioinspired Structural Solutions Shape and Morphology as Inspiration Surface and Texture as Inspiration The exercise sessions aim to expand and consolidate the knowledge gained during the lectures by defining course projects to be developed in groups. Each group will define a distinct bioinspired solution to an engineering structural problem, design an adapted structure, and analyze its structural performance using commercial FEA software (e.g., ABAQUS). Students will receive brief training on how to design, model, and optimize such structures with CAD software and analyze them with FEA software. Possible experimental tests are also envisioned for some of the suggested solutions. Additionally, some seminars are planned during the course. National and international experts from the relevant fields will be invited to provide insights into advanced bioinspired structural design solutions related to the topics covered in the course.
Modalità d'esame
Prova orale obbligatoria Progetto/i - Elaborato/i obbligatorio, di gruppo, con revisioni periodiche, con presentazione/discussione finale The final evaluation consists of the development and presentation of a team project, followed by an oral exam. The oral exam can only be taken in the semester when the project evaluation has been successful. Students' project will be evaluated based on their contribution to the teamwork, their presentation, and whether their project has addressed the main defined goals. The final grade is determined by combining the marks from the final project report and presentation (50%) and the oral exam (50%). To pass the course, students must achieve a total grade between 18/30 and 30/30. Project Reporting and Presentation: Students will be divided into groups. During the exercise sessions, each group will work on the identification, design, implementation, and analysis of an individual bioinspired structural solution that can be studied in the form of periodic structures. The structure will be modeled and analyzed using finite element analysis. Possible experiments can be envisioned on some of the most promising designs developed by the students, which will be 3D-printed. Students are required to prepare a comprehensive written report on the project’s development phases and results. Oral Exam: The student’s knowledge of the major principles of bioinspired structural design discussed during the course and their ability to apply these principles to engineering structural problems will be evaluated. The oral exam will consist of questions about the underlying mechanisms, physical phenomena, and theoretical implementation regarding the examples and design concepts covered during the course, both in lectures (theoretical nature) and exercises. Depending on specific organizational needs, the oral exam may require composing written answers, subject to discussion with the course instructor.

This course explores advanced topics in Computational Fluid Dynamics (CFD), focusing on the practical application of simulation techniques to the complex flow phenomena encountered across engineering. Students will learn to develop and implement CFD models for a broad range of flow processes, including compressible flows, chemically reacting flows, multiphase flows, moving boundaries and grids, and heat transfer. Building on the introductory course Computational Fluid Dynamics: Fundamentals, it emphasizes advanced simulation strategies rather than the detailed mathematical formulation of numerical methods. Throughout, students will work through real-world examples drawn from mechanical engineering and related fields, and dedicated sessions will address the development and integration of custom models for simulating complex physical phenomena.
Learning Outcomes By the end of the course, students will be able to translate complex multiphysics fluid dynamics problems—typically described by partial differential equations (PDEs)—into discretized systems of equations and solve them using appropriate numerical techniques. This includes a solid understanding of numerical stability, convergence, and consistency, applied to a wide range of scenarios from single-phase to multiphase flows, incorporating heat transfer and moving grids. Lectures and exercise sessions will enable students to: Identify the most suitable modeling approach for complex, multiphysics problems. Select the optimal simulation strategy and level of approximation for solving advanced flow scenarios. Evaluate the impact of setup choices on CFD simulation results and effectively conduct post-processing. Implement custom models within a CFD framework to extend the software’s capabilities. The project laboratory will provide students with practical experience to: Set up a well-posed compressible flow problem, selecting appropriate numerical schemes and solvers. Generate computational grids for multi-region and multi-domain configurations. Configure CFD simulations, including boundary and initial conditions, and define grid motion strategies. Choose and apply the most appropriate multiphase modeling approach (e.g., Lagrangian, Eulerian, Eulerian dispersed, Eulerian VOF). Post-process and analyze simulation results to extract meaningful insights.
Programma
Course Topics CFD Simulation of Compressible Flows: Extension of pressure-based solution methods to compressible flow regimes. Density-based approach. Treatment of boundary conditions for subsonic and supersonic flows. Overview of available solvers for compressible flow simulations and techniques for effective post-processing. Moving Grid Strategies: Approaches for handling small deformations, including mesh-to-mesh interpolation. Techniques for managing large deformations through mesh topology adaptation.

Obiettivi formativi
This is a course about exploring random systems using computer simulations. Indeed, almost every mathematical model describing systems or phenomena of interest is hampered by uncertainties, although very often uncertain features or inputs are not accounted for. The goal of the course is to introduce computational tools aiming at: (i) describing uncertainty sources in general systems, with special emphasis on differential models, and (ii) analyzing the impact of uncertainty on systems ’ outcomes, in terms of both uncertainty propagation from inputs to outputs, and input parameter estimation from noisy observations. A wide range of additional techniques enabling uncertainty quantification for complex problems will also be considered such as, e.g., surrogate models, reduced-order models for differential problems, multi-fidelity and neural network-based strategies, data-driven dynamical systems, thus providing also a general introduction to recent paradigms in scientific machine learning.
Both versions of the course have the following common learning goals:
At the end of the course students are expected to be able to simulate statistical models - and run with Python - computational experiments aimed at: describing possible sources of uncertainty, quantifying the impact of uncertainty on numerical models, sampling from distributions of quantities of interest involving the simulation of physics-based models, applying Monte Carlo methods and their extensions, performing parameter estimation, building surrogate or reduced-order models by handling neural network-based or GP regression models.
Leveraging on their engineering forma mentis and on the skills in computational statistics acquired in the course, students are expected to be able to evaluate the practical and statistical significance of the outcome of their numerical simulations, to quantify its uncertainty, and to propose efficient and reliable strategy to reduce computational complexity.
Students are expected to be able to communicate and transfer the results and interpretations of their computational experiments using effective graphical or analytical means, suitable for the problem at hand and the findings of the analysis. Moreover, the students of the 8 CFU version of the course are expected to have a basic understanding of further topics related with data assimilation, sensitivity analysis, and data-driven dynamical systems.

The course is organized in a series of lectures that also include practical lab sessions. Lectures will provide the theoretical background; practical Lab sessions will provide algorithms' implementation and examples of application of the considered methodologies by using Python codes. Part 1. Monte Carlo methods & Stochastic Simulation Generating random samples from simple distributions (inversion method, transformations), acceptance-rejection sampling. Generating random fields. Karhunen-Loève expansion. Monte Carlo methods Variance reduction techniques: antithetic variables, importance sampling, control variates, stratification, latin hypercube sampling. Quasi Monte Carlo methods Part 2. Surrogate models & Scientific Machine Learning Dimensionality reduction: singular value decomposition Gaussian processes & GP regression Neural Networks (e.g., autoencoders & variational autoencoders) Projection-based & deep learning-based Reduced Order Models Data-driven Dynamical Systems: dynamic mode decomposition, sparse identification of nonlinear dynamics, extensions Part 3.

Modalità d'esame
Prova orale obbligatoria The oral exam covers the content of both theoretical lectures and practical Lab sessions, according to the sizing (5CFU/8CFU) of the course. During the exam, students are required to present the detailed solution of two selected assignments (among a list of assignments proposed during the practical Lab sessions), commenting both the numerical results obtained and the computational procedures employed, and to answer to theoretical questions related with the topics of the course. Assignments will require students to apply, adapt, or extend some of the methods presented during the course to selected case studies. The assignments will be evaluated during the oral examination and must be submitted to the examiners by the deadline communicated during the classes. Theoretical questions will assess students' knowledge of the methodologies covered throughout the course. During the examination, students will first be required to sketch written answers to the theoretical questions, before presenting and discussing them with the examiners. In the 5+3CFU form, a n additional assignment has to be carried out, which might also take the form of a critical analysis of a recent scientific paper related to the course's topics. The course will be based on a selection of chapters of the following books, class notes, and some selected scientific papers provided:

Obiettivi formativi
Modern computer systems routinely process high-value information, including financial and personal data, economic transactions, and intellectual property. At the same time, they are increasingly pervasive, continuously available, and interconnected, making information security a major engineering challenge. Security engineering is the discipline of designing and building secure systems. It is inherently interdisciplinary, combining cryptography, software engineering, network security, and political and social considerations. This course provides a broad introduction to cybersecurity and to the methods used to design, validate, and ethically test security mechanisms. Lectures examine the main components of computer and information systems, with particular attention to their security subsystems. Students will analyze vulnerabilities, understand how they can be exploited, and learn how to prevent similar design and implementation errors.
Expected learning outcomes Knowledge and understanding Students will acquire broad knowledge of fundamental security technologies, their limitations, and common vulnerabilities and exploitation techniques. Applying knowledge and understanding Students will be able to identify and assess basic security issues in systems, networks, and applications; evaluate and improve proposed solutions; design high-level solutions to security problems; exploit simple application vulnerabilities in controlled environments; and develop basic patches. Making judgements Students will be able to comparatively evaluate security threats, vulnerabilities, mitigation mechanisms, and alternative solutions; reason about trade-offs; and assess risks in realistic scenarios. Communication Students will use appropriate terminology to explain security issues and justify security choices clearly. Lifelong learning skills Students will be able to update their knowledge independently and apply risk and security assessment principles to complex systems, including non-digital contexts.

Programma
This course offers an in-depth overview of control valves and their application in fluid dynamics and process control. It begins with fundamental concepts and a classification of valve types, distinguishing between linear and rotary designs. Students learn basic sizing techniques for both liquids and gases, using key equations and interactive sizing software. The course also explores valve flow characteristics, system interaction, and valve positioning. Advanced topics include cavitation and flashing, noise prediction (hydrodynamic and aerodynamic), and actuator types and principles. The connection between valves and process dynamics —such as control loops and optimization—is also examined. Hands-on laboratory sessions allow students to characterize valves, observe cavitation and flashing, and perform advanced analyses of control processes. Practical exercises focus on valve sizing for various flow conditions and mapping performance curves. Overall, the course blends theoretical knowledge with practical experience, enhanced by the involvement of industrial partners from the valve sector, to equip students for real-world challenges in valve selection, design, and process integration.

The course aims at providing all of the basic skills and knowledge required to effectively design and construct an electric motor. The objectives are highly interdisciplinary because they deal with a number of different physical and engineering aspects, namely, defining the magnetic circuit and magnetic field sources, defining the mechanical architecture referring to strength, compliance, thermal aspects and basic feasibility. The engineering aspects are made rigorous by deriving the optimal solutions in the Pareto sense. Particular attention is devoted to the design and construction of automotive motors. The course aims at highlighting an ever-occurring paradigm within automotive engineering that a single component requires almost all of the competences that are needed to design the whole vehicle. The course aims also to show to the students the importance of competences pertaining to other specialized courses, either electrical or mechanical, addressing the design and construction of electric motors.

The students will acquire knowledge and understanding on -how electric motors are conceived -how windings and/or magnets are placed into an electric motor -the importance of an efficient magnetic circuit -winding a stator -how performing a preliminary design of an electric motor -how dealing with strength problems -how dealing with compliance problems -how dealing with basic construction engineering problems -how dealing with thermal problems -how dealing with noise problems -how optimizing the whole motor by means of multi-objective programming Concerning the ability to apply the acquired knowledge and understanding, students will be able to -choose the proper electric motor as function of the required mission (traction, brake actuation, servo-actuators...) -complete and analyse the design of an electric motor -apply multi-objective optimization to find optimal solutions for electric motors with respect to a given mission Through a real design case study, the students will also acquire the skills to formulate a judgment, meaning to define a technical specification, find autonomously the problem input data, apply proper models, perform a critical analysis of the obtained results and explain them. They will also acquire the ability to discuss in a team the proposed design. Furthermore, through the assigned case study, students will gain the ability to autonomously -define models of different complexity, with the objective of obtaining a suitable trade off between the accuracy of the solution and the required computational cost -evaluate the benefits of the design optimisation and propose new solutions -critically discuss their project and propose improvements that they assume necessary to limit the effect of the simplifications introduced for didactic constraints Finally, students will improve their communication skills, being able to write reports presenting the developed projects. In particular, the students are requested to prepare their reports addressing the following issues define a design specification describe the theoretical background of the applied methods explain the assumptions, approximations introduced and their impact on the results show the relevant results highlight the impact of the optimisation methods learned in the course on the final design, with respect to a traditional design approach.

Obiettivi formativi
Digital technologies are increasingly used to support the design, operation and control of manufacturing systems. In industrial environments, effective decision-making requires models that represent the current state of the system, account for variability and uncertainty, and incorporate the interaction between human operators and digital technologies. The course introduces methods and tools for developing and using digital models of manufacturing systems, with particular emphasis on Digital Twins and human-centred production environments. Students will learn how to represent manufacturing resources, processes, products and human activities, and how to use these representations to support monitoring, analysis and short-term operational decisions. Within the Management Engineering curriculum, the course contributes to the development of the ability to: analyse the functions, processes and interactions of business and industrial systems, considering their economic, environmental and social implications; formulate and solve industrial problems using scientific and engineering methods; integrate data, models and digital technologies to support decisions in complex manufacturing environments; evaluate the role of human operators in digitally enabled production systems. The course supports these programme-level capabilities through the modelling, analysis and control of human-centred manufacturing systems.
By the end of the course, students will be able to: model the main elements and behaviour of a manufacturing system using Digital Twin concepts; select and apply appropriate digital and AI-based methods to a manufacturing problem; integrate models, data and software tools into a coherent application; analyse results and assess the assumptions, limitations and industrial value of the proposed solution; communicate the methodology and results of a technical project. Each student will complete an individual project on one of the topics covered in the course. The specific knowledge and technical skills developed will therefore depend partly on the selected project. Students may exchange general methodological information and use shared software components or datasets when authorised by the instructor, but the submitted analysis, implementation, results and report must be individual.
Programma
1. Digital representations of manufacturing systems Digital Factory, Digital Twin and AI-enabled manufacturing concepts. Digital representation of resources, processes, products and their interactions. Manufacturing data models, standards, ontologies and Digital Twin architectures.

Prova orale obbligatoria Progetto/i - Elaborato/i obbligatorio, di gruppo, senza revisioni periodiche, senza presentazione/discussione finale Students pass the course after successfully passing a mandatory Lab Work and a mandatory oral exam. Via the oral exam, it is possible to test students’ ability to autonomously form judgements and the ability to communicate learnt contents. Students should answer two main questions formulated by the professor. The oral exam gives a grade 18/30 <= Go <= 28/30. If Go < 18/30, the student fails the exam and goes to the next call. The mandatory Lab Work can yield up to 4 additional points (Lw). Since the Lab Work is mandatory, every student is required to do it to pass the exam. The Lab Work must be submitted at the end of the course and before the first exam call according to the date declared by the professor during the course. If the Lab Work is not sufficient, the group cannot attend the first exam call and receives indications by the professor on how to fix it. In case of absence from certain laboratory sessions, the student can retrieve the related material through the other group colleagues and/or via WeBeep. The professor considers the number of absences from the laboratories and, after consulting all group members, will decide whether to consider the requirement for the repeatedly absent student to complete the Lab Work satisfied. The final grading formula is: Gf = Go + Lw. Only by successfully passing the Lab Work, the maximum grade of 30 and 30 and praise can be achieved.

Practical experiences will allow students to apply the concepts learned during the course to real-case scenarios. Students will analyze mechanical systems, modelling components in their operative scenario, including degradation and failure mechanisms typical of system operation, then applying algorithms to statistically identify the health condition of a system and use the updated Digital-Twin to statistically predict the system future evolution. More specifically:
The course is aimed at providing the Students with practical concepts and instruments for modelling complex systems in their operative environment or asset, including degradation phenomena through the Digital-Twin.
The course will merge multidisciplinary inputs from different sectors (mechanical, materials, data science, management engineering, etc.) in a unique and coherent virtual framework that can be used for design, operation and monitoring optimizations.
The course will introduce students to the field of health and usage monitoring of structures and systems, specifically focusing on the role of models (and Digital-Twins) in the diagnosis and prognosis of mechanical (and, in general, industrial) systems and components, exploiting statistical pattern recognition and machine learning to interpret changes in their measured features.
In terms of acquired knowledge and understanding, students will be able to: Examine scenarios where Digital-Twin models can bring benefits Predict benefits and drawbacks of modelling methods in the framework of mechanical (and, in general, industrial) system design, operation and monitoring optimization Interpret existing application studies in the literature and implement methodologies appropriate for solving complex problems, both systematically and creatively.

Programma
In the era of digitalization, Digital-Twins have been proposed as a mean to mimic the system life cycles in a virtual scenario. Specifically, a Digital-Twin is a virtual replica that mirrors the real system condition, resulting from the combination of a master model (typically developed during design) with real-time data (digital shadow) potentially captured during system operation. In this context, the digital-twin, constantly updated and refined during operation, can include information about potential damage/faulty scenarios and, thus, be used to simulate new information that is necessary for real-time assessment of the actual system condition (e.g. for structural damage identification) and for predictive asset optimization (e.g. for operation and maintenance optimization). This makes the Digital-Twin a crucial element in the development of any health and usage monitoring system. To this aim, the following topics are treated throughout the course: Introduction: the role of the Digital-Twin within system operation. Evolution of design and maintenance criteria (from safe life to damage tolerant design, from fault driven to predictive maintenance). Introduction of Health and Usage Monitoring Systems as a means toward predictive maintenance. Application of Digital-Twins for system health and usage monitoring as input to the operation and maintenance optimization. Operational evaluation: review of different degradation processes affecting mechanical components in their operative environment. Models for prediction of damage progression and failures (fatigue, fracture, corrosion, creep, etc.) and general system performance degradation (e.g. fouling, battery state of life/charge, etc.). Motivation to the development of Digital-Twins for health and usage monitoring. Digital master model creation. In this practical module the student will model continuous degradation processes and discrete system failures into the physical model of the component/system (within the Matlab Simulink/Simscape/Simevents framework). Realistic application scenarios will be considered, with final goal to simulate either changes in signal features captured by potential sensors or, in general, system performance degradation. Improve simulation speed. In this module the students will learn how to use machine learning (specifically artificial neural networks) to approximate input-output relationships simulated with a detailed model. The resulting surrogate model is a requirement enabling the stochastic adaptiveness within the following Monte-Carlo sampling framework. Development of an adaptive and stochastic Digital-Twin. In this module the student will use Bayesian inference to fuse the information from models with the continuous stream of information by sensors, resulting in a real-time statistical adaptation of model parameters to fit the real component or system subject to degradation. The Bayesian Model Updating will also offer a natural framework for combination of prior knowledge on the system parameters (including potential damage) with the new information from sensors. Overview of conditional probability distributions and Bayes theorem Monte-Carlo sampling strategy for approximated Bayesian inference in multiple-parameter updating. The need for an efficient sampling strategy: forced sampling. Metropolis-Hastings Markov Chain Monte-Carlo methods for statistical pattern recognition Sequential Importance Sampling/Resampling (particle filter) for tracking and prognosis of non-linear non-Gaussian systems subject to degradation

Obiettivi formativi
This course aims to provide the basics of low-voltage electrical safety by exposing, discussing and understanding safety issues with reference to electrical industry regulations. Electrical safety is a very important section of electrical installations, because it must contextually protect electrical equipment/systems under any operating condition (transient, steady state, abnormal or fault conditions) and human beings. The course will mainly cover the safety of people from electrical systems, understood as the set of protection systems suitable for preserving the health and safety of human beings interacting with electrical systems. Bearing in mind that low-voltage may involve environments frequented even by people untrained in the selection and use of electrical materials and components, a key role in safety lies with the type of electrical system implemented and the competence of the designer and performer of the system itself. The course will first recall the legal norms that elect safety against hazards as a right of all citizens and workers, as well as indicate the means and institutions that should guarantee this right. Some definitions of general terms such as safety and risk will then be given and the methodology for identifying the acceptable level of safety, which, as is well known, is never absolute, will be discussed. Finally, methods of protecting people from the hazards of electricity suitable for different low-voltage distribution systems will be addressed. The course will consist of theoretical class lectures and seminars and exercises given by professionals in the field in order to also present the critical issues that may be encountered during the design and implementation of the system as well as the interaction with other branches of engineering with which the systems must coexist.
Upon passing the exam, the student will have achieved: Knowledge of the legal norms that elect safety against injuries as a right of all citizens and workers and indicate the means and institutions that should guarantee this right. Ability to recognize and interpret the purpose, structure and operation of low-voltage systems under normal and faulty conditions. Knowledge of the effects on the human body resulting from the flow of an electric current. Knowledge of basic concepts related to the problems of interrupting electric current and choosing protection against electrocution. Ability to interpret and apply concepts regarding safety for people and related regulatory requirements. Knowledge of protection systems for people to avoid hazards from direct contact with active parts of electrical power systems. Knowledge of protection systems for people to avoid hazards from indirect contact with grounded parts of electrical power systems. Ability to assess lightning-related risks to people and/or economic or cultural heritage. Knowledge and understanding of the main interactions with other branches of engineering to ensure adequate protection of people.

Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere Prova orale facoltativa (a scelta dello studente) Assessment methods for students in Energy Engineering The exam consists of a compulsory written examination and an optional oral examination. The written examination consists of two numerical problems related to all topics covered in the course, together with some multiple-choice or graphical-response questions. The test is designed to assess students’ ability to:
Assess the performance of energy conversion plants, or sections thereof, at the design point by carrying out mass, chemical species, and energy balance calculations.
Validate the operating conditions of energy conversion plants, or sections thereof, under off-design conditions, using the operating principles of the system components.
Evaluate the Levelized Cost of Electricity (LCOE) and CO2 emissions of energy conversion plants. There are five written exam sessions in each academic year:
Two at the end of the first semester
Two at the end of the second semester
One in September The written test is assessed on the basis of the formal and numerical solutions provided by the student, as well as the correctness of the answers to the questions. Examinees may consult any printed material; however, the use of phones, tablets, or personal computers is not permitted. After the test, the solutions are distributed, and each student may request to withdraw from the exam. In this case, the test will not be corrected and will not affect the student’s record, resulting in a “postponed” outcome. If the student requests grading, the possible outcomes of the written test are as follows:
The maximum score achievable in the written test is 32 out of 30.
Scores of 8 or lower result in a “rejected” outcome. A “rejected” outcome prevents the student from registering for second sitting in the same exam session. This restriction applies only to the first of the two sittings following the end of the semesters.
Scores between 9 and 17 result in a “postponed” outcome.
With a score between 18 and 32 allows the student passes the written examination. After passing the written examination, students may choose between two options: They may complete the examination by accepting the grade obtained in the written test, up to a maximum final grade of 24. Accordingly, students who obtain a written-test score higher than 24 but decide not to take the oral examination will have a final grade of 24 recorded. Alternatively, they may take the oral examination, which may be held on a different date within the same examination session. The oral examination is intended to confirm and, where appropriate, modify the final grade; the grade may therefore be increased or decreased. The oral exam assesses the student’s understanding of the fundamental aspects of the course and examines cause-and-effect relationships affecting plant operation when design parameters and boundary conditions change. One or more questions will concern topics covered during the course exercises. Students who decline the grade awarded at the end of the oral exam must repeat the written examination. The professor nevertheless reserves the right to conduct an additional oral examination to verify the results emerging from the written test. Assessment methods for students in Mechanical Engineering The exam consists only of a compulsory written examination. The written test is exactly the same as that taken by Energy Engineering students, but the maximum score is set to 32 out of 30. The professor nevertheless reserves the right to conduct an additional oral examination to verify the results emerging from the written test.

The course aims to teach the correct use of the Finite Element Method as a tool for mechanical design, focusing therefore on the more practical aspects required by industry today, without, however, neglecting the theory. The aim is to convey the need for sound critical analysis of the results obtained from any calculation code, to be compared with first-order approximate manual calculations. All possible sources of error will be highlighted: from the use of an element type unsuitable for a particular phenomenon to be simulated, to mesh density; from boundary conditions to numerical errors produced by poorly conditioned matrices; and the consistency of the units of measurement used. The importance of interpreting the results will be emphasised, as well as how to use the figures obtained from the computational models in relation to the various standards for the design of connection elements (e.g. welds) Tools will be provided for verifying structural integrity and fatigue life using the results produced by the computational models
By the end of the course, students should be able to develop moderately complex computational models containing several interconnected components, and should have a good degree of confidence that the model is correct. They should have the necessary skills to develop independently and progress, should they find themselves (or strongly wish to) working as structural engineers at a professional level.

Obiettivi formativi
At the onset of a technological transition in which Fuel Cells and Batteries, the key electrochemical energy conversion and storage (EECS) devices, are starting to play key roles in mobility at all scales, the purpose of this course is to enable Mechanical Engineering students without previous knowledge in the fields of electrochemistry and physical chemistry, to achieve independence in approaching EECS science and technology problems. Specifically, this course will: (i) allow effective further self-study of the details available in the original literature; (ii) provide the basis for professional work in the EECS field, both in industry and academia. The mission of this course is thus to provide students with the key conceptual tools for critical and quantitative thinking of Fuel Cell and Battery Engineering fundamentals, oriented towards design and control activities, as well as integration in a wider system-oriented technological vision.
From the methodological standpoint, this is a self-contained course, specifically designed for Mechanical Engineering Students, that can be attended also by other Industrial Engineering Students with CVs lacking dedicated chemical and physical background. Special care has been devoted in the design of this course, on the one hand to provide the relevant physical and chemical essentials, and on the other hand to ensure the attainment of a fully technological treatment of the subject matter. Moreover, repetitions of contents conveyed in other eligible courses delivering information in EECS has been avoided with utmost thoroughness, so that this course can be fruitfully followed both by students who have or have not attended them, rendering this course fully independent from other ones offered by Politecnico di Milano. In particular, the Students will: i) acquire knowledge regarding the electrochemical and physico-chemical processes implemented in Fuel Cells and Batteries and controlling their operation under ideal and realistic conditions; ii) become acquainted with the technological implementation of the above-mentioned processes in practically relevant devices; iii) be exposed to the key experimental methods to assess and quantify the functional properties and performance of EECS devices; iv) develop skills in the use of basic mathematical tools to model EECS devices and predict their operation and degradation. The basic modelling tools taught in this course will be modular, and can be naturally extended to more face sophisticated cases that the Students might encounter in their activities beyond the scope of this course.

The course begins with an introduction to atomic and molecular structures, followed by an analysis of the different types of intra- and inter-molecular interactions. These interactions are used to determine the potential energy of materials and to classify them into the following key categories: ionic, covalent, molecular, macromolecular, and metallic. Model potentials appropriate for describing these interactions and the molecular arrangement at the nanoscale will be examined in detail, considering both crystalline and amorphous domains, as well as short- and long-range order. Particular attention will be given to the correlations between atomic, molecular, and supramolecular structures and the resulting macroscopic properties of materials (structure–property relationships). The course also considers the principal tools for describing crystal structures in the solid state, introducing the mathematical and geometrical concepts required for their analysis. Building on these foundations, the fundamentals of materials physics will be presented to support the understanding of key structural, electrical, optical, and thermal properties. Selected characterization methods will be introduced, including X-ray diffraction (XRD), vibrational spectroscopy, molecular modeling, and differential scanning calorimetry (DSC).
After attending the course and following a positive evaluation, regarding the Dublin Descriptor 1 (DD1) of knowledge and understanding, the students will be able to: describe intra- and inter-molecular interactions and evaluate the potential energy of materials using appropriate model potentials; understand the molecular and crystal structure of materials through the use of suitable geometrical, graphical, and mathematical tools; demonstrate knowledge of key characterization methods such as X-ray diffraction, vibrational spectroscopy, molecular modeling, differential scanning calorimetry, and dynamic thermo-mechanical analysis, and their practical applications. Regarding the DD2 of applying knowledge and understanding, the students will be able to: analyze and interpret the structural features of different classes of materials (ionic, covalent, molecular, macromolecular, and metallic) at various length scales; compute and correlate macroscopic properties—electrical, optical, thermal, and mechanical—with micro- and nano-scale structure, using appropriate physical and mathematical models.

The objective of this course is to provide a state-of-the-art overview of the current knowledge of the mechanical behaviour of granular materials, with particular emphasis on Engineering applications. Granular materials are large collections of solid moving particles whose mass is so large (usually at least 10 20 molecular masses) not to be subject to thermal motion at room temperature, and which dissipate energy whenever they interact. Everyday examples of phenomena involving granular materials of Engineering interest comprise: sand storms, rock and snow avalanches, debris flows and sediment transport; transport, storage and manipulation of seeds, rice, corns, sugar and coffee, chemical and pharmaceutical products like pills and powders, rocks; motion of red blood cells in small vessels; traffic flow; planetary rings. It is ubiquitous in nature, since mountains, soil and the bottom of the sea are predominantly granular. In industry, the most processed materials (with the exception of water) are in a granular form, and problems with their handling are causing a staggering loss of 5% of the world energy budget (which corresponds to over 300 billion euros every year). In the course, the students will be exposed to the two commonly used methods to model these materials, i.e., the continuum approach and the discrete, particle-based approaches, specialized to deal with the different physical states of granular matter. Special attention will be given to the fundamentals of the discrete element method simulations and its applications to a variety of Engineering problems. The students will be exposed to the latest scientific researches in the field and would gain hands on experience by means of course projects and assignments
Knowledge and understanding Once passed the exam, the student: understands the different physical states of granular materials knows how to model granular and granular-fluid systems using continuum mechanics knows how to employ discrete element methods to model particulate systems understands the limits of applicability of the possible approaches Ability to apply knowledge and understanding Once passed the exam, the student: is able to formulate and solve simple boundary value problems involving granular flows is able to determine the pressure distribution in granular packings is able to use freely available molecular dynamics simulators is able to implement and solve 1D and 2D granular flows of Engineering applications using discrete numerical solvers
Programma
Introduction with examples of applications of granular mechanics. Continuum models. Balance equations for granular and granular fluid flows Granular gases. Kinetic theory of granular gases: binary collision; Maxwell’s elementary transport phenomena; velocity distribution function; constitutive relations in the dilute and dense limit; breaking of molecular chaos; role of friction, stiffness and shape.

Pressure distribution in container. Ordering and crystallization. Granular liquid crystals. Axial-symmetric, non-spherical particles. Alignment and consequences on the modelling. Discrete Element Methods. Event-driven and soft-particle approaches. Freely available molecular dynamics simulators: LAMPPS and MERCURYDPM. The students will participate in small groups to either a numerical or a combination of numerical and experimental laboratories, upon availability and attitude of the students, for a total of 20 hours. Numerical laboratory. Simulations of particle flows of interest for industrial partners (e.g., pressure-driven flows in conduits; free-surface, inclined flows in channels). Experimental laboratory. Sinking of intruders in granular crystal solids (measurements via image analysis techniques).
Modalità d'esame
Progetto/i - Elaborato/i obbligatorio, di gruppo, senza revisioni periodiche, con presentazione/discussione finale The course is organized in lectures and practical lessons where the topics of the course are presented and applied to practical examples, solving numerical exercises through analytical solutions and numerical solutions obtained using Matlab codes that are partially developed by the students. During the practical lessons the students will be guided to use numerical solvers (LAMMPS or MERCURY3D) to compute the dynamics of granular flows in Engineering applications. Students, divided in small groups of maximum 3/4 participants, are required to partially develop either a numerical or an empirical project on one of the following topics: inclined, gravity-driven granular flows; pressure-driven granular flows; sinking of intruders in granular packings. The requirements are to use the knowledge acquired during the lectures and applied to the examples studied during the practical lessons to perform additional investigations that will be presented during the final exam. The examination is performed through an oral test. During the oral test, the students are asked to present the methodologies employed in their project and the quantitative results that they have obtained. The oral part is also composed by answering questions on the topics of the course.

Numerical solution (using the finite volume, finite element or finite difference methods) of problems involving conduction with different boundary conditions.
Thermal analysis of systems (typically simplified satellites) using the multi-node lumped parameter approach. NOTE: for students attending the 5 ECTS (CFU) course (e.g., Nuclear Engineering and Mechanical Engineering students), Topics 3.4, 3.5, 5.2 and 5.3 are NOT part of the exam program (even if they may be still useful in their fields).
Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere Students will pass the course after successfully take a written exam (there will be no oral exam). Via this exam, it will be possible to test students’ acquired knowledge and understanding and its autonomous application, also in combined ways, together with their ability to independently form judgements. The written exam consists of two parts: A first part (A) including multiple-choice questions focused on the main concepts of the theory part of the course. These questions are aimed at verifying the learning of the fundamental aspects about the different heat transfer modes and about the methodologies and devices used for thermal analysis and thermal control. A second part (B) including two exercises aimed at verifying the ability to critically model and solve a heat transfer problem analytically or by basic use of numerical techniques, making proper simplifications and assumptions if needed, and checking the correctness (also numerical) of the results. More specifically, in these exercises it is verified the ability to create a conceptual model of a heat transfer problem, to convert it into a system of equations (by using equivalent circuits, energy balances and all the toolbox of analytical results and experimental data/correlations that are described in the theory part of the course) and to solve it. Final Grading The final exam will be marked as follows. Answering correctly to a minimum number of questions in Part A will be a necessary condition for the exam to be sufficient. Given this threshold, the number of correct answers to the questions of Part A will give either a bonus or a penalty to be summed to the total number of points obtained by the student in Part B. Exercises of Part B will be divided in queries, whose answers will be evaluated only as correct/wrong, and correct answer to each query will give some points. The total number of points for part B will be 30, and the maximum increase from the questions of Part A will be of 3 points. Students obtaining at least 18 total points will pass the exam; 33 points will result in 30 cum laude.

Learning Goals (Obiettivi dell'insegnamento) This course aims at outlining relevant developments in manufacturing and service industries with regard to automation and digitalization developments. This is especially tailored towards the new Industry 5.0 (I50) concept of human-centered operations systems. Therefore, the course wants to address the challenge of Human-System Interaction ( HSI ) and the design of successful human-centered systems. HSI is critical in modern operations and supply chain management due to the increasing use of automated and digital systems. Counter-intuitively during automation and Artificial Intelligence (AI) applications, the human factor is increasing in importance in terms of operational performance and business success. In most empirical evidence studies within operations management we find that hybrid systems are performing best, combining the strengths of automated and computer systems with human workers. Consistently with premise, the course has the following structure: This course aims to provide the main methodologies and criteria for analysing, designing and managing hybrid, i.e. human-digital work systems in logistics, manufacturing and supply chain systems. After an overview on the strategic importance of human-centered operations systems, the course addresses the 3 main pillars of hybrid work systems from a human perspective: Safety, Efficiency and Trust. The last section of the course is dedicated to application examples and blueprints for successful human-centered operations systems. The course fits into the overall program curriculum pursuing some of the defined general learning goals. In particular, the course contributes to the development of the following capabilities for the participants: Understand context, functions, processes in a hybrid (human-technology interaction) operations system and the impact on business performance Identify trends, technologies and key methodologies in a specific application domain (specialization streams like manufacturing, retail logistics or healthcare services) Design solutions applying a scientific approach (Analysis, Learning, Reasoning, and Modeling capability deriving from a solid and rigorous multidisciplinary background) to face challenges and opportunities in business, service and industrial environments with HSI

“Impact Engineering” brings together state-of-the-art and methodological approaches aimed at understanding how materials and structures behave under extreme loading conditions, allowing for a specific “fit for purpose“ design. Extreme loading conditions encompass large deformations, severe yielding, fracture, impacts (low, high, and ballistic velocity), blast, etc; in general terms, they are characterized by nonlinear phenomena that make the structural design a challenging task. Impact engineering is one of the fore fronts of structural design and offers rigorous and cutting-edge tools and methods able to optimize protective, resilient, and robust structures under harsh conditions.
This course aims at providing its participants with knowledge and understanding of the mechanical behavior of material and structures in case of exceptional loads and critical outcomes. The course will focus on the behavior of different materials under extreme loading conditions (including specific calibration tests), structural design approaches to safety under extreme conditions (with relevant examples), experimental and modelling instruments to investigate, predict and mitigate the risk of structural collapse. Concerning the ability to apply the acquired knowledge and understanding, the students will be able to solve practical design applications by using analytical and numerical tools, and to critically analyze the results. Through activities based on Finite Element Method applications, the students will also acquire the skills to formulate a judgment with advanced tools, understanding their assumptions and limitations, and to analyze and critically discuss the results. Furthermore, through the assigned case studies, students will gain the ability to autonomously design and assess components and systems subjected to extreme loadings. Finally, students will improve their communication skills, being able to write final technical reports for case studies.

Modalità d'esame
Prova orale obbligatoria Progetto/i - Elaborato/i obbligatorio, di gruppo, senza revisioni periodiche, con presentazione/discussione finale The course evaluation mode includes a mandatory Lab Work and a mandatory oral exam. The mandatory Lab Work gives a grade 18/30 <= Lw <= 25/30. Since the Lab Work is mandatory, every student is required to do it to pass the exam. The Lab Work must be submitted and a presentation must be given by each group at the end of the course and before the first exam call according to the date declared by the professors during the course. The Lab Work presentation gives a grade 0/30 <= Gp <= 3/30. If the Lab Work is not sufficient, the group cannot attend the first exam call and receives indications by the professor on how to fix it. In case of absence from certain laboratory sessions, the student can retrieve the related material through the other group colleagues and/or via WeBeep. The professors consider the number of absences from the laboratories and, after consulting all group members, decide whether to consider the requirement for the repeatedly absent student to complete the Lab Work satisfied. Via the oral exam, the students’ ability to autonomously form judgements and the ability to communicate learnt contents will be tested. The oral exam questions are focused on the Lab Work. The oral exam grade Go gives up to 4 points. The final grading formula is: Gf = Lw + Gp + Go. Only by successfully passing the Lab Work, its presentation and the oral exam, the maximum grade of 30 and 30 and praise can be achieved.

The student develops soft skills working in groups during laboratories, developing the final project and realizing the presentation of the project work. Finally, he/she develops the ability to learn autonomously, because the student is encouraged to improve his/her understanding of topics by finding documentation available in the literature.
Programma
The course is based on an "multiscale" approach, presenting digital models of the human body at different hyerarchical levels. In particular, the attention is focused on ergonomic applications, on modelling/simulating tissues and organs of the human body, and on the development of patient-specific orthoses and prostheses. The course starts presenting the basics of multibody techniques to model spatial kinematic chains, and in particular virtual manikins. The second part is focused on the reconstruction of models of the human body (or districts of it), starting from different acquisition techniques, such as laser scanning, structured light or medical imaging (CT scan, MRI,...). Applications of these models to develop customized medical devices are then discussed. Examples of finite element analyses are presented to evaluate deformations, stresses, and device–tissue interactions, while computational fluid dynamics is introduced to simulate blood flow in reconstructed vessels, considering different levels of modelling approximation. Eventually, applications of 3D printing in medicine are discussed in detail. All the topics are presented in lectures and directly experimented in lab activities.

Obiettivi formativi
The aim of the course is to provide students with the methods and tools required to develop integrated robotic manufacturing systems combining robots, manufacturing processes, sensors, end-effectors, digital models and artificial intelligence technologies. The course considers the robot as a flexible platform for performing manufacturing and production tasks. Students will therefore learn to approach a robotic application starting from the requirements of the product, process and production system rather than from robot programming alone. Through the laboratory projects, students will learn how to: translate product and manufacturing requirements into specifications for a robotic system; select and integrate robots, sensors, end-effectors and auxiliary equipment; design digital and physical robotic manufacturing cells; develop and validate robotic tasks using online, offline, no-code and AI-based approaches; integrate robot motion with manufacturing-process requirements; perform experimental trials and identify stable and repeatable operating conditions; evaluate the technical feasibility, quality and performance of a robotic manufacturing solution; manufacture and validate a physical demonstrator. Particular attention will be given to the interaction between robotic motion and the technological process. In the welding project, for example, students will consider the relationship between component design, joint configuration, process parameters, robot trajectory and final manufacturing quality. The course also introduces emerging AI-based approaches to robotic task development through compact demonstrative platforms. Students will explore how visual information and task instructions can be translated into robot actions and will test these methods through a physical manipulation application. Machine vision and sensing will be presented as enabling technologies for robot guidance, workpiece localisation, trajectory correction and process monitoring. These technologies will be considered as integral components of the robotic manufacturing system. The laboratory activities currently include two complementary projects. Project A – AI-Based Programming on a Demonstrative Robotic Platform Students work in groups using compact robotic demonstrators. Each group receives its own robotic platform and develops the physical setup, workspace and experimental procedure. The project focuses on an AI-enabled pick-and-place application. The manipulation task is intentionally accessible, allowing students to concentrate on system integration, AI-based perception, robot–environment interaction, testing and performance evaluation. The demonstrative nature of the platform allows students to rapidly modify the setup, compare alternative solutions and explore emerging AI-based programming methods through direct hands-on experimentation. Project B – Industrial Robotic Welding of Complex Geometries Students develop a complete manufacturing case study based on a three-dimensional welded component. Starting from the desired function and geometry, they design the individual parts according to the constraints of sheet-metal manufacturing and laser cutting. Before producing the final component, students perform preliminary welding trials, investigate the influence of the main operating parameters and identify suitable process conditions. They then manufacture, assemble and weld the final demonstrator, evaluating its geometrical accuracy, weld quality and overall production feasibility. The project connects component design, manufacturing-process development, robotic integration and physical production within a single industrially relevant activity. To complement the laboratory projects, the course includes industrial visits covering three different positions within the robotic manufacturing value chain: a supplier of robotic technologies, sensors or end-effectors; an OEM or system integrator responsible for developing industrial machinery and robotic cells; an industrial end-user implementing robotic manufacturing technologies in production. This structure provides students with a comprehensive view of the different professional perspectives of a robotic manufacturing engineer: developing enabling technologies, integrating complete production systems and deploying them in an industrial environment.
By the end of the course, students will understand the principles, architectures and enabling technologies of modern robotic manufacturing systems, as well as the relationships between robotic operation, manufacturing-process requirements and industrial performance (DdD1 Knowledge and Understanding) Students will be able to apply engineering methods to design, integrate and validate robotic manufacturing solutions, combining digital tools, physical systems, sensing technologies and experimental activities (DdD2 Applying Knowledge and Understanding) Students will be able to evaluate alternative technical solutions, interpret experimental evidence and make justified decisions concerning system configuration, process conditions, performance and feasibility (DdD3 Making Judgements). Students will be able to communicate technical objectives, design choices, experimental methods and project results in a clear and structured manner, while collaborating effectively within multidisciplinary teams (DdD4 Communication Skills). Students will be able to independently approach new robotic manufacturing technologies, acquire the knowledge required to use unfamiliar tools and adapt their methods to emerging industrial and research challenges (DdD5 Learning Skills). The course provides students with a broad and transferable engineering methodology applicable to robotic manufacturing systems beyond the specific projects developed during the laboratory activities.

Obiettivi formativi
This course provides students with the methodologies and tools required for the integrated modeling and experimental validation of wind turbines. Students will develop advanced modeling and measurement techniques for wind energy systems. They will learn how to formulate aeroelastic models capable of predicting the coupled response of aerodynamic loads, structural dynamics, and atmospheric boundary layer winds. The course will also cover the selection, installation, and calibration of sensors for measuring key quantities on operating wind turbines. These concepts will be applied through hands-on experimentation using a physical scale model of a multi-megawatt wind turbine in a wind tunnel laboratory. Students will learn how to process and analyze both aeroelastic simulation results and experimental measurements to extract key performance indicators and characterize the dynamic response of wind turbines under realistic operating conditions.
As a result of passing the examination, the student: knows the fundamental principles, generalizations, theories, and concepts related to the testing of wind turbines; is able to extract meaningful indicators from data inherent to the operation of a wind turbine; independently, makes and communicates the design choices made regarding the quantities of interest in validating a wind turbine system and the best method of measuring them.
Programma
These problems will be faced through the course: physics-based and data-driven modeling of the wind turbine system and its subdomains (aerodynamics, actuators, structural components), choice of sensors needed to control a wind turbine scale model and measure its response in realistic operating conditions; design of control strategies for wind turbine scale models for wind tunnel testing; collection and processing of data related to the operation of a wind turbine that are obtained through wind tunnel experiments.
Modalità d'esame
Prova orale facoltativa (a scelta dello studente) Progetto/i - Elaborato/i obbligatorio, di gruppo, senza revisioni periodiche, con presentazione/discussione finale Students will work in teams to develop a project focused on the modeling and experimental testing of a wind turbine. The project will be carried out throughout the laboratory course and will integrate all the topics covered during the semester. The final assessment will consist of a project presentation and discussion before the course instructors. Students will be evaluated on their understanding of the methodologies employed, the quality of the work performed, and their ability to interpret and communicate the results. In addition, students may choose to undertake an individual oral examination covering the theoretical concepts presented during the course. The outcome of the oral examination may be used to adjust the project grade.

Obiettivi formativi
The course is focused on the Life Cycle Assessment (LCA) methodology. The aim is twofold: to introduce students to the theoretical fundamentals of the methodology and then to apply them to evaluate the environmental sustainability of materials and industrial processes. A significant portion of the course will be devoted to applying the LCA methodology to representative real-life cases, mainly taken from chemical, food, and materials industries. The course is organised as a computer laboratory. The open-source software, OpenLCA, is the tool adopted. Lectures will be held in classrooms with electrical connections at every desk, and students are required to bring their own laptop computer.
Upon successful completion of the course, students will be able to: explain the principles and methodological framework of Life Cycle Assessment (DdD1); use OpenLCA software to perform Life Cycle Assessment studies (DdD2); select appropriate environmental impact assessment methods and indicators for different assessment goals (DdD2); apply the LCA methodology to simplified industrial case studies (DdD2); interpret and critically discuss the results of Life Cycle Assessment studies (DdD2); critically interpret and evaluate published LCA studies (DdD3).
Programma
Sustainability assessment: introductory concepts. Fundamentals of Life Cycle Thinking (LCT) and Life Cycle Management (LCM) Life Cycle Assessment (LCA): historical background, ISO standards, procedures, applications, data quality and data sources. Eco-indicators: measurement methods, environmental and damage impact categories, impact quantification; carbon footprint and climate change. Materials End-of-Life: open and closed-loop recycling, re-use, waste-to-energy, waste-to-materials, waste-to-chemicals, waste management processes. Use of the software OpenLCA
Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere The final assessment consists solely of a written examination, organised in two sections: Part A: closed questions on theory fundamentals and one case study (half an hour) Part B: numerical application of the LCA methodology to a simplified case study using the software OpenLCA (2 hours) The final grade (maximum 33 points) is obtained by combining the scores of Part A (maximum 9 points) and Part B (maximum 24 points). Final grades are then converted to the Italian grading scale, with scores strictly higher than 31.5 awarded 30 cum Laude. The test will last two and a half hours, with a short 15-minute interval between Part A and Part B. Part A consists of multiple-choice questions and short-answer questions covering theoretical concepts and one simplified case study. During Part A, no electronic support or any other type of support is allowed. In Part B, students will perform a simplified Life Cycle Assessment using OpenLCA and answer quantitative questions based on the obtained results. During Part B, students must use their own notebook computer. Printed notes, textbooks and other reference materials are permitted. Students may access online resources during Part B. Mobile phones are not allowed. There is no limit to the number of examination sessions students may take, and there is no oral examination. At the end of the course, students may take a voluntary mock examination under exam conditions. The simulation replicates the structure and timing of the official examination and offers an opportunity for self-assessment. Students are required to bring their own notebook computer for the practical laboratory sessions and for Part B of the final examination.

Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere Prova orale condizionata (a scelta del docente) Progetto/i - Elaborato/i facoltativo (a scelta dello studente), di gruppo, con revisioni periodiche, senza presentazione/discussione finale The final exam consists of a mandatory written part (2/3 of the score) and a second part involving either a project or an oral exam (1/3 of the score). However, in order to achieve a mark egual to 30 (or 30 cum laude) the oral exam is mandatory.The written exam consists of: Quantitative Exercise(s): practical exercise(s) with numbers where students are required to design a logistics system (e.g. a warehouse, a picking system, …) applying the models learnt during the course (ILOs 1, 2) Theoretical Question(s): open question(s) where the students have to prove to be able to both present/describe logistics strategies/solutions and apply them to specific contexts/problems (ILOs 1, 2, 3) The score of the written exam must be positive (at least 18/30) to pass the exam. The project - which is elective for all the students - consists of a group work (typically 5 students) performed throughout the course, in which the students are asked to apply the knowledge gained during the lessons to a real case (ILO 3). The evaluation of the project will be made in two steps, an intermediate one (during the course) and a final one (at the end of the course). If the students take the project and get a positive score (at least 18/30), the final mark will be a weighted average between the mark of the Written exam (2/3) and the mark of the project (1/3). The oral exam consists of questions that might span all the topics of the course (ILOs 1, 2, 3), and it is mandatory for the students who do not gain a passing score (at least 18/30) in the project. Access to the oral examination is allowed only if the written exam is sufficient. The oral assessment must be taken in the same session of the written exam. If the students get a positive score in the oral exam (at least 18/30), the final mark will be a weighted average between the mark of the written exam (2/3) and the mark of the oral exam (1/3). The teaching material consists of: (i) set of slides supporting the in-class lectures; (ii) practical lessons/exercises; (iii) supplementary exercises; (iv) selected references (selection of papers and chapters of relevant books, videos, etc.). All the material will be available before the related lesson on https://beep.metid.polimi.it.

This course aims to introduce the main concepts of Machine Learning applied to Mechanical Systems. The course topics are wide to provide the students with a general understanding and best practices with the most relevant machine learning approaches. Nowadays, AI and Machine Learning have pervaded all fields of science and are widely spread even within engineering. Obviously, the pervasiveness of Machine Learning has declined within the different engineering disciplines: if the methods and algorithms can be “general”, the applications for mechanical engineering are “particular”. This is the purpose of the course, which aims to develop and apply the general methods to applications that are specific to mechanical engineering. For this reason, the course introduces the student to various Machine Learning methods applicable to wide fields of science, together with specific applications in the system identification and control of mechanical systems (i.e., for modeling, monitoring, optimization, and control). Indeed, the course will address data-driven and hybrid (i.e., physics-informed) algorithms that make use of the known physics of the target system. Together with a theoretical study of these methods/techniques, students will be trained with practical examples to evaluate the performance of the different algorithms developed in MATLAB and Python. In this regard, the course will provide the fundamental notions of Python and PyTorch to allow students full autonomy in the execution of the course exercises.
By the end of the course, students will learn content and practices according to what is defined in the learning objectives. Descriptor Cycle Description 1 - knowledge and Understanding MSc Have demonstrated knowledge and understanding within the main field of study, implementing methodologies appropriate for solving complex problems, both systematically and creatively. In terms of acquired knowledge and understanding, students will be able to know the methodologies and the principles to describe in mathematical terms a target mechatronics problem to be solved by applying machine learning techniques. Descriptor Cycle Description 2 - applying knowledge and understanding MSc Ability to critically, independently, and creatively solve problems with some originality in new or unfamiliar situations environments within multidisciplinary contexts related to their field of study. Concerning the ability to apply the acquired knowledge and understanding, students will be able to: Select the proper ML technique to solve a target problem; Formulate the ML problem based on the knowledge of the system. Descriptor Cycle Description 3 - making Judgment MSc Ability to synthesize and integrate knowledge; Ability to deal with complex issues both systematically and creatively, make sound judgments even on the basis of incomplete or restricted information. Through exercises and programming, students will also acquire the skills to formulate, implement, and evaluate the performance of the target ML algorithm for the considered problem.
Programma
The course deals with signal processing, modeling, optimizing, and controlling mechanical systems with ML techniques. The fundamental concepts of Artificial Intelligence and Machine Learning (ML) are first discussed theoretically for the following topics: (i) Intro to ML and Neural Networks, (ii) Physics-Informed Neural Networks, (iii) Anomaly Detection, (iv) Bayesian Optimization, (v) Preference-Based Optimization, (vi) Reinforcement Learning, and (vii) Imitation Learning + Diffusion Policy. The students will be able to practice both academic and real-life examples, where different algorithms are applied in MATLAB and Python environments.
Modalità d'esame
Prova orale obbligatoria Progetto/i - Elaborato/i obbligatorio, di gruppo, senza revisioni periodiche, con presentazione/discussione finale The exam consists of one group Python project to be selected among the proposed ones. The theoretical oral examination is mandatory and individual. The project presentation and the oral examination will be performed together. The group size will be determined by the Professor before starting the project, and based on the project complexity. The group has to submit a PowerPoint presentation + report + code.

This course aims to introduce the main concepts of Machine Learning applied to Mechanical Systems. The course topics are wide to provide the students with a general understanding and best practices with the most relevant machine learning approaches. Nowadays, AI and Machine Learning have pervaded all fields of science and are widely spread even within engineering. Obviously, the pervasiveness of Machine Learning has declined within the different engineering disciplines: if the methods and algorithms can be “general”, the applications for mechanical engineering are “particular”. This is the purpose of the course, which aims to develop and apply the general methods to applications that are specific to mechanical engineering. For this reason, the course introduces the student to various Machine Learning methods applicable to wide fields of science, together with specific applications in the system identification and control of mechanical systems (i.e., for modeling, monitoring, optimization, and control). Indeed, the course will address data-driven and hybrid (i.e., physics-informed) algorithms that make use of the known physics of the target system. Together with a theoretical study of these methods/techniques, students will be trained with practical examples to evaluate the performance of the different algorithms developed in MATLAB and Python. In this regard, the course will provide the fundamental notions of Python and PyTorch to allow students full autonomy in the execution of the course exercises.
By the end of the course, students will learn content and practices according to what is defined in the learning objectives. Descriptor Cycle Description 1 - knowledge and Understanding MSc Have demonstrated knowledge and understanding within the main field of study, implementing methodologies appropriate for solving complex problems, both systematically and creatively. In terms of acquired knowledge and understanding, students will be able to know the methodologies and the principles to describe in mathematical terms a target mechatronics problem to be solved by applying machine learning techniques. Descriptor Cycle Description 2 - applying knowledge and understanding MSc Ability to critically, independently, and creatively solve problems with some originality in new or unfamiliar situations environments within multidisciplinary contexts related to their field of study. Concerning the ability to apply the acquired knowledge and understanding, students will be able to: Select the proper ML technique to solve a target problem; Formulate the ML problem based on the knowledge of the system. Descriptor Cycle Description 3 - making Judgment MSc Ability to synthesize and integrate knowledge; Ability to deal with complex issues both systematically and creatively, make sound judgments even on the basis of incomplete or restricted information. Through exercises and programming, students will also acquire the skills to formulate, implement, and evaluate the performance of the target ML algorithm for the considered problem.
Programma
The course deals with signal processing, modeling, optimizing, and controlling mechanical systems with ML techniques. The fundamental concepts of Artificial Intelligence and Machine Learning (ML) are first discussed theoretically for the following topics: (i) Intro to ML and Neural Networks, (ii) Physics-Informed Neural Networks, (iii) Anomaly Detection, (iv) Bayesian Optimization, (v) Preference-Based Optimization, (vi) Reinforcement Learning, and (vii) Imitation Learning + Diffusion Policy. The students will be able to practice both academic and real-life examples, where different algorithms are applied in MATLAB and Python environments.
Modalità d'esame
Prova orale obbligatoria Progetto/i - Elaborato/i obbligatorio, di gruppo, senza revisioni periodiche, con presentazione/discussione finale The exam consists of one group Python project to be selected among the proposed ones. The theoretical oral examination is mandatory and individual. The project presentation and the oral examination will be performed together. The group size will be determined by the Professor before starting the project, and based on the project complexity. The group has to submit a PowerPoint presentation + report + code.

Obiettivi formativi
The course presents the two most important manifestation of ordering phenomena in solids beyond the crystal lattice: magnetism and superconductivity. The two are crucial for the understanding of the transport properties of crystalline materials, and can be exploited in a multitude of applications. Magnetism and superconductivity are governed by microscopic interactions, ultimately among electrons, but the macroscopic phenomenology is the result of interatomic interactions and dimensionality. Bose-Einstein condensation (BEC) and superfluidity are also presented as they share with magnetism and superconductivity the property of being macroscopic quantum phenomena. The objective of the course is thus to provide a broad knowledge and understanding of ordering phenomena in solids. Phenomenology, experimental methods and theoretical models are considered and confronted. More broadly the goal is to introduce the students to the real world of advanced condensed matter research, with special emphasis on phenomenology and experimental insight.
Lectures and seminars will allow students to: Know the fundamental concepts of ordering phenomena Recognize the different types of magnetic order Know the general phenomenology of superconductivity, superfluidity and BEC Determine which experimental methods can be used in the study of magnetism and superconductivity and, in general, of ordering phenomena in solids Read and understand original research papers in the fields of magnetism and superconductivity Present a brief seminar on basic concepts and advanced examples on modern magnetism and superconductivity Therefore, after passing the exam, the student will be able to: DD1 - Understand the principles of magnetism and order phenomena, know the terminology related to them, employ the basic models applicable to them DD2 - Recognize analogue of magnetism and superconductivity in other contexts and apply models ant techniques in new contexts of physics and technology DD4 - Communicate their own perception of physics phenomena in a formal presentation and elaborate on them

Modalità d'esame
Prova orale obbligatoria Progetto/i - Elaborato/i obbligatorio, individuale, senza revisioni periodiche, con presentazione/discussione finale The exam consists of two parts held during a single interview, in English. 1) A seminar of 20-25 minutes, on a subject pre-assigned by the teacher. The student has to present the general concepts of the theme in a correct and complete way, providing some examples at the level of the lectures and of the text book. The student is also invited to look for original examples, applications, interconnections with other subjects, to demonstrate a higher level of understanding. A PowerPoint presentation is best suited for the seminar, but black/white board option is also possible. 2) Two or three questions on the core of the course as presented in the lectures. The student is requested to answer at the black/white board to show their understanding of the basic concepts and notions of the course. Theoretical and experimental aspects will be valued equally important. A fully successful exam (27-30/30) will be deemed when a solid and broad mastering of the concepts of ordering phenomena in solids is demonstrated. An average grade (22-26/30) will be the result of fairly complete understanding of individual themes but with limited interconnection among subjects. A pass level (18-21/30) will correspond to a minimum knowledge of individual notions.

Obiettivi formativi
The course aims at providing students an overview of the knowledge to the design of experiments focused on the mechanical characterization at small scale (10 -3 - 10 -6 m) for materials and micro-devices. In the first part of the course, the practical and theoretical concepts useful for the implementation of experiments aimed at the study of mechanics at small scale will be provided throughout examples of instrumentation and experiments adopted at the laboratory LAB 3M and LABMEMS&3D. The second part of the course will focus on practical activities (design of experiment and experimental setup) aimed at providing students the possibility to apply the course topics by means “learning by doing” and “team working”.
Lectures, exercise sessions, and passing the examination will allow students to (DdD1): analyze and understand the goals, assumptions and requirements associated to an experimental apparatus for mechanical and electromechanical measurements; identify and define software solutions for the control of experimental equipment; identify and define software solutions for results acquisition and elaboration. More specifically, the laboratory project will allow students to (DdD2): apply basic concepts of mechanics of solids and structurers to the design of experimental equipment; make experience on the use of CAD software for the design of simple mechanical elements; write a requirement specification document; write a design specification document; analyze software code written by others; summarize and present the results achieved during the analysis and specification activities.

Obiettivi formativi
This course provides an integrated framework for the modelling, analysis and design of mechatronic systems. It builds on the students’ background in mechanical engineering and extends it with advanced tools for system modelling, control design, actuator selection and sizing, and measurement techniques. Particular emphasis is placed on the interaction between mechanical components, actuation systems, sensors and control algorithms. Students will learn how to analyse the dynamic behaviour of mechatronic systems, define suitable performance requirements, select appropriate components and design control strategies that ensure effective and reliable operation. By combining mechanical modelling, control theory and system-level design, the course enables students to approach mechatronic systems as integrated engineering solutions rather than as separate subsystems. This perspective prepares them to address complex design challenges and to contribute to innovation in advanced mechanical and mechatronic applications.
By the end of the course, students will understand the main principles for designing advanced control strategies for linear and nonlinear systems, as well as the role of state observers in reconstructing non-measured variables and filtering noisy measurement data. They will therefore acquire a solid understanding of the modelling, analysis and control of mechatronic systems, with particular attention to the interaction between mechanical dynamics, actuation systems, sensors and control algorithms.
Programma
The course is organized into the following parts. Part 1: Introduction to Mechatronic Systems Definition and scope of mechatronics; historical development and interdisciplinary nature of the field; examples and industrial applications. Part 2: Modern Control Techniques Static optimization; optimal control of linear and nonlinear systems; dynamic programming; differential games; reinforcement learning; overview of additional nonlinear control approaches, including robust and adaptive control. Part 3: State Observers Kalman filter; Extended Kalman filter; Unscented Kalman filter; Particle filter. Students interested in further exploring specific topics may refer to the books listed below.
Modalità d'esame
Prova orale obbligatoria Progetto/i - Elaborato/i facoltativo (a scelta dello studente), individuale, senza revisioni periodiche, senza presentazione/discussione finale The exam consists of an oral discussion on the topics covered during the course. During the oral exam, students will be asked not only to demonstrate knowledge of the main concepts, but also to elaborate on them, showing that they have understood how the concepts are connected and how they can be applied to mechatronic systems. In addition, students will be offered approximately three assignments related to the practical/training part of the course and one assignment related to the theoretical part. These assignments are not mandatory, but they provide an opportunity to improve the final grade.

Programma
Nanomagentism is a modern discipline devoted to the study of magnetism in nanoscale objects. The "nano-world" opens unforeseen possibilities to develop new devices and paradigms exploiting the spin and orbital angular momentum of electrons and other quasi-particles (e.g. domain walls, magnons) propagating in engineered magnetic structures. Spintronics, in particular, is a branch of nanoelectronics aiming at developing new electronic devices taking advantage of the spin degree of freedom in addition to the charge of carriers. The program will consist of lectures and exercises devoted to these topics: Micro and NANO magnetism Demagnetizing field, magnetostatic energy. Landau magnetic free energy and its contributions (exchange, anisotropies, magnetostrictions). Domain walls. Micromagnetic simulations (OOMMF). Coherent magnetization reversal (Stoner Wohlfart model) and reversal via propagation of domain walls. Magnetic nanoparticles. Domain wall conduits. Magnetic coupling in multilayers (Néel coupling, Exchange bias, Bilinear coupling) Classical-Spintronics Two currents model and spin dependent scattering. Giant magnetoresistance in CIP and CPP configurations. Spin accumulation and Valet-Fert model. Tunneling magnetoresistance and magnetic tunneling junctions. Non volatile magnetic memories (MRAMs) and magnetic sensors. Spin transfer torque. Magneto-electric coupling. Spin injection, manipulation and detection in semiconductors. Spinorbitronics Rashba based devices and Spin-FET. Spin currents. Direct and inverse spin Hall effect. Antiferromagnet spintronics.

Nonlinear systems exhibit richer phenomena than their linear counterparts, at the price of increased complexity. To navigate this complexity, the course first presents the main tools to analyze dynamical properties of nonlinear systems, among which Lyapunov methods and changes of variable play a prominent role. Through these tools, then, the course illustrates well-established techniques to design controllers for relevant classes of nonlinear systems, as described below. Mechanical and robotic systems, oscillators and electrical circuits are used to exemplify these techniques. The course is methodological and aims at providing students with a toolkit of techniques for nonlinear (control) systems with an eye towards computational implementations of some of these techniques. This toolkit and the understanding gained in the course should enable students to deal with the instances of nonlinear (control) systems they will encounter and to autonomously delve into more advanced topics within the broad area of nonlinear control.
After the lectures and exercise sessions of this course, the student
knows the fundamental tools for the analysis of dynamical properties of nonlinear systems (DD1);
knows some of the most used techniques for control design of nonlinear systems (DD1);

Modalità d'esame
Prova orale obbligatoria Progetto/i - Elaborato/i obbligatorio, di gruppo, senza revisioni periodiche, con presentazione/discussione finale The course assessment will consist of a composite individual evaluation (home-work + oral discussion) and a team project for both the 5CFU and 8CFU version of the course. The composite individual evaluation will consist of two parts: fi rstly, a homework where each student will be required to provide the solution of an execise in terms of code necessary for getting the solution; then, an oral discussion where the student will be required to solve an exercise and to answer some theoretical questions. Failing the rst part will prevent to access the second part of the composite evaluation. The composite individual evaluation will be scored on a scale from 0 to 30, the maximum evaluation being 32/30. It will be passed upon obtaining a score larger or equal to 18/30. The exam evaluation will account for the degree of clarity of the exposition and for the correctness of methods and computations. For each question students will be asked to report both the method used and the numerical solution obtained, and to critically discuss the latter one. The team project will consist of an analysis of a real dataset, to be conducted in teams of 2 to 4 students, using the models and methods introduced in the course. The team projects will be presented during and at the end of the course in an open workshop that will take place after the end of the semester. For the groups whose students are not willing to give the written exam during the winter semester a second date will be available during the summer session. Each team will receive an evaluation in a scale from 0 to 30. More details about the expected project development will be given in a dedicated lesson. The final individual grade will be obtained as a weighted average of the grades obtained by the student in the two parts of the evaluation: 2/3 grade of the composite exam + 1/3 grade of the project. During the exam, the students will have to:
Demonstrate the degree of knowledge and comprehension of the key aspects of the course, presenting the used methodologies in a clear and exhaustive way;
Demonstrate their ability to apply the learned notions to solve exercises and real problems, on any of the topics covered in the course.

Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere The course is organized in lectures and tutorials. Design of plants are also proposed on different technologies. The exercises are functional to the understanding of topics and to the preparation of the exam (the ability to solve the proposed exercises is a necessary but not sufficient condition for passing the exam). The exam consists of two tests: a written test (duration 90 minutes) that is a practical test based on two numerical problems and a theoretical written test based on open-ended questions and mulitple choice questions (duration 60 minutes). The final mark will result as a weighted average between the practical (60%) and theoretical part (40%). The two tests can be carried out on two separates dates within the same Academic Year. To proceed to the theoretical exam an evaluation equal/above 16/30 for practical test is mandatory. The two tests aims to ascertain the degree of understanding of the fundamental aspects of the course, from the theoretical working principle of the various renewable technologies, to the operating strategy of a plant in off-design conditions, the forecast of its annual energy output, the evaluation of the environmental balance and the economic assessment of an investment. In particular the written test will aim at evaluating student's ability in the calculation and preliminary design of renewable power plants, assessing the electricity production, economic feasibility and environmental benefits, in terms of avoided emissions and energy saving. The theoretical test will aim at evaluating the understanding of the physical concepts underlying design and operation characteristics specific to different technologies. For the 5-CFU course, the exam has the same structure and the only difference resides in questions that will be limited to the topics covered.

The first aim of the course is to let students understand the functional requirements and performance of rail vehicles. To attain this, the basic information are given on how rail vehicles are conceived, designed, produced, tested, used and eventually disposed or recycled. In particular, one key objective of the course is to describe how the main subsystems of the rail vehicle work (functional requirements and performance). The course deals with both rail vehicles for passengers and rail vehicles for freight transport. We start with the basic functions, described by mathematical models, and we finally understand why rail vehicles are being made as they appear and which could be the future developments. Particular attention is devoted to historical development of vehicles, to understand their evolution process in view of Maglev and Hyperloop. Another aim is to provide practical experience by means of seminars delivered by companies and visiting overhaul workshops. One aim refers to developing critical reasoning on how rail vehicles have to be exploited, based on their inherent physical caharacteristics. This can be made by team working and discussing the results of own work. The above aim is related to the other aims referring to -developing presentation skills and -acquiring information useful to own project exercise The course is divided into three modules. The first module deals with general aspects of rail vehicle design. The second module is focused on topics concerning the mechanical design of rail vehicle system or components like wheelsets or bogies.

Modalità d'esame
Prova scritta facoltativa (a scelta dello studente), con prove in itinere Prova orale obbligatoria Type of exam The exam is oral only. Number of questions 2 Questions Rail: 1 question on lectures FAQ in the file “questions – rail vehicle.doc” on webeep 1 question on exercises (the exercises are: the assignment and the summaries of technical visits) Duration Typically, one day is needed by the teacher to complete the exams. It is safe not to consider this as a rule. In case many candidates are to be examined, the exam may last more than one day. Elapsed time Writing the first question(s) and answering the second question(s) requires about 1.5 hours. Practical issues during exam To make easy and speedup the examinations, the first question is answered by students not in front of the teacher. Students sit and write the answers taking the time they need. Then they discuss with the teacher their answers. Extended dates As a rule the exam dates are the ones officially defined. Pre-exams During the course a couple of pre-exams can be taken by students. The first pre-exam is made during the programmed time span for such kind of pre-exams (usually mid April). The second pre-exam is made at the end of the course. The qustions that will asked are given by te teacher in advance. 20 questions are given for the first pre-exam and 20questions are given for the second pre-exam. Each pre-exam lasts nealy one hour. At the first pre-exam 10 questions will be asked among the possible 20. The same for the second pre-exam. The final exam will consider the results of the two pre-exams, additionally, a question on the exercise(s) will be made. Who fails one of the two pre-exams has to take the full exam as explained above. The pre-exams are available until 31 July of the current academic year. After this period, the teacher may decide that the student will have to take the full exam as explained above. Mark The final mark is the non-weighted mean of the marks obtained answering the questions. In case of pre-exams, t he final mark is the non-weighted mean of the marks obtained by answering the questions and by answering a question on exercise. Since the seminars and technical visits are integral part of the course, each missing activity causes, respectively, the drop of approximately one unit from the final mark.

The circular economy approach addresses manufacturing challenges by extending the lifespan of components and products through repair, remanufacturing, and reuse. Today, repairing and remanufacturing have become increasingly valuable in various industries due to the need to reduce costs, improve sustainability, and extend the life of mechanical components and parts. The repair of metal components, which was once accomplished through manual processes and practical-empirical techniques, has emerged as a significant aspect of manufacturing sustainability in sectors like automotive, aerospace, energy production, advanced mechanics, and rail and ship transportation. The course provides the engineering foundations of repairing and remanufacturing technologies within the framework of circular manufacturing. It introduces product life extension strategies for engineering components manufactured from metals, polymers and composite materials, with particular emphasis on high-value metallic products employed in aerospace, energy, tooling, biomedical and transportation industries. Building on students' background in materials science, manufacturing processes, inspection and component qualification, and sustainability assessment, this course enables them to design and evaluate repair strategies from both technical and economic perspectives. The program starts with an overview of the physical principles underlying the main repair technologies and their distinguishing characteristics. It then examines the current state of the art, highlighting the most relevant industrial applications, emerging technologies, and future trends in repair and remanufacturing. The course subsequently focuses on automated repair and remanufacturing systems, addressing the transition from manual and experience-based practices to intelligent, digitally enabled and robotic manufacturing.

The course allows to understand what exactly is a road vehicle and how it could be designed. Off-road vehicles are also dealt with. The course aims to provide the basic information on how road or off-road vehicles are conceived, designed, produced, tested, used and eventually disposed or recycled. In particular, one key objective of the course is to describe how the main subsystems of the vehicle are conceived. Designing a vehicle is not designing a generic complex machine, issues concerning product and production processes must be dealt with. We start with the basic functions, described by mathematical models, and we finally understand why vehicles are being made as they appear and which could be the future developments. Particular attention is devoted to historical development of vehicles, to understand their evolution process. Practical experience is given by means of seminars delivered by companies, experiencing driving simulator tests, running on track. The course has the following goals. One goal is to enable students to conceive and design vehicles and their sub-systems. Critical reasoning is fostered. One goal refers to developing autonomous design skills, by team working and discussing the results of own work (e.g. design of a susension system). Data to solve design problems given during assigments are to be found by students, as in an actual job in an industrial environment. Other aims refer to -developing presentation skills and -acquiring information useful to own project exercise. The ability of getting information for a design job is fostered. Other two goals of the course refer to -feel with own body -and recognize- the different sources of vibrations of the vehicle related to ride comfort, with the aim of establishing a link between subjective feeling and mathematical models for design purposes. -feel with own body undesteering, oversteering and stability issues during extreme manoeuvres, with the aim of establishing a link between subjective feeling and mathematical models for design purposes.
By the end of the course, students will learn contents and practices according to what defined in the learning objectives. In terms of acquired knowledge and understanding, students will be able to: identify the industrial environment referring to automotive production describe how vehicles are conceived, starting from the basic architecture issues show how the main road vehicle subsystems are designed (wheels, brake, suspension, drivetrain, body) define the performance for a car define the active safety and ride comfort for a car (combining theoretical issues and practical experience) define both the basic passive safety of a car and the noise-vibration harshness of the body Concerning the ability to apply the acquired knowledge and understanding, students will be able to: design the suspension system of a car Through project, laboratory visit, practical classes on the road or on track, and through assignments students will also acquire the skills to formulate a judgment, meaning to compare different design solutions pertaining to road vehicle components (tyres, wheels, brakes, powertrains, bodies) perceive the ride comfort of a road vehicle and identify deign solutions perceive the understeering and oversteering of a car and identify design solutions Furthermore, through the assigned group projects and practical activity will gain the ability to autonomously compose his/her own project while defining the performance of a car formulate the design of a vehicle or of a vehicle-subsystem by defining the complete set of technical specifications, finding autonomously the data, applying proper models, perform a critique of the results assess in a team discussion the obtained results (activity performed during the team projects referring to assignments) Finally, students will improve their communication skills, being able to present and discuss during the exam their assignments, in particular the mechanical drawings acknowledge the limit of their skills and knowledge, in order to foster further study during their professional life

Modalità d'esame
Prova orale obbligatoria Progetto/i - Elaborato/i obbligatorio, di gruppo, con revisioni periodiche, con presentazione/discussione finale T ype of exam Students will pass the course after successfully take an oral exam. A ssessment Via this exam, it will be possible to test students’ s p ecific knowledge and skills listed below. Knowledge on how wheels, brake, suspension, drivetrain, body are designed The drawing of the suspension system and the suspension arm is always required and discussed Always the teacher tries to check whether the exercises have been made by the student, asking detailed questions that are easily answered if a direct involvement has occurred. The skills that are assessed are -ability to conceive a vehicle -either road or rail- referring to its general characteristics, by finding the proper data wherever available -ability to design vehicle subsystems, like suspension (car) or wheelset (rail) with autonomous reasoning -ability to make judgement, referring to the definition of the performance of a car -ability to learn by combining practical and theoretical experiences, reference is made to ride comfort and to active safety of road vehicles -ability to re-organize the notions of the course in a creative way to produce new design solutions The teacher checks that students have both learned and understood the topics of the course. Actually learining is different than undersanding. Understanding requires the ability to re-organize the notions in a creative way to solve unreferenced issues. For this scope, students are urged to study not only on notes but also on authoritative sources (not simply from internet pages, often incorrect). Number of questions For 10 CFU: 4 questions (2 to be answered during the written part, 2 on exercises) For 5 CFU: 2 questions (1 to be answered during the written part, 1 on exercises) One additional question may be asked to check that the notions provided during the course can be combined by the student to answer complex problems (e.g. how could you design a hub carrier an for ultra-light vehicle?) Questions FAQ in the file “questions – road vehicle.doc” on webeep P ractical procedure of the exam The first part of the oral exam is generally written, i.e. students are asked one or two general questions. They seat and, taking their time, answer such general questions by drawing schemes or mechanical subsystems or plots, writing mathematical derivations. Then they discuss the written part with the teacher who completes the exam asking additional questions, in particular on exercises. W orking time of the exam Writing the first question(s) on lectures and answering the second question(s) on exercises requires about 1.5 hours. Duration Typically, one day is needed by the teacher to complete the exams for all of the enrolled students. It is safe not to consider this as a rule. In case many candidates are to be examined, the exam may last more than one day. Extended dates As a rule the exam dates are the ones officially defined. Exceptions are possible but are limited to very special cases, and only in the first session of exams. Final Grading The final mark is the non-weighted mean of the marks obtained answering the questions mentioned above. Since the seminars and technical visits are integral part of the course, each missing activity causes, respectively, the drop of approximately one unit from the final mark.

The final goal of the course is to provide methods to control uncertain linear dynamical systems. Three main steps are needed to lead the students to such a goal. First, techniques are provided for the shaping and quantification of the uncertainties, in terms of suitable definition of system norms. Second, the problem of robust stability at the face of uncertainties are tackled via a Lyapunov function approach. Finally the problem of feedback control of uncertain systems is deal with through parametrization and model matching synthesis. Some classical, as well as modern techniques, will be covered so that the student will acquire the methodological skills to tackle a wide corpus of robust analysis and robust control problems for uncertain systems. The theoretical and exercise lessons are complemented with laboratory sessions using Matlab/Simulink to test some topics of the course.

Il corso ha lo scopo di introdurre i concetti principali relativi alla dinamica dei rotori e alla diagnostica. La dinamica dei rotori è la base della progettazione e del funzionamento di molte macchine: turbine di qualsiasi tipo utilizzate per la generazione di energia, motori aeronautici, motori elettrici, compressori centrifughi, ecc. Pertanto, la dinamica dell'intera macchina e dei suoi componenti principali, come alberi, cuscinetti, tenute e palette sono dettagliatamente analizzati. Vengono anche presentati diversi strumenti di progettazione ed esempi pratici. La diagnostica è un requisito emergente nei moderni sistemi meccanici al fine di tempi di fuori servizio e ridurre i costi operativi. Molto spesso, i guasti avvengono negli stessi componenti che sono analizzati dalla dinamica dei rotori e questo rende le due parti del corso strettamente collegate. Anche in questo caso vengono introdotte tecniche all'avanguardia, basate sia sul modello di sistema sia sull'analisi dei dati. Tutti gli argomenti sono analizzati dal punto di vista pratico e teorico, con diversi esempi di applicazione in macchine reali.

All sectors of our societies, from aircraft traffic to healthcare, electric grid and finance have been undergoing unprecedented levels of digitalization with beneficial consequences on efficiency and flexibility of services provided. However, this dependence on and seamless integration of technology into the daily activities and operations exposes these systems to various manmade and natural threats, with possible negative consequences on their security and even well-being of citizens. The constantly evolving threat landscape pushes the current concept of protection towards a resilience status. Moreover, the high interdependency and complexity of sectors require a multidisciplinary approach to educating the workforce called to safeguard it. Putting this strategy into practice, in turn, requires an unprecedented partnership and information sharing between the public and private sectors at all levels. After successful completion of the course, students will be able to identify the vulnerability of the critical sectors in our economies to cyber risks, and recognize how to tackle them from a public sector perspective in order to define policies and programs, as well as put in place actions required to govern it. More specifically, they should be able to: - acquire hands-on knowledge in identifying physical and cybersecurity concerns in the critical infrastructure systems and their centrality in modern societies (principal threats and challenges, who owns them) - gain understanding and critically analyse approaches and methods of risk assessment and mitigation of persistent threats and incidents (how are threats/risks assessed & mitigated, are they useful in paving the way to resilient systems?) - develop knowledge about the specificity and interrelatedness of various CI systems - analyse trends in the global system connected to the evolution of cyber risk, interpret how they affect government activities and define policies, programs and road maps for governing it - develop mathematical skills to model and forecast the risks - apply logic models to critical infrastructure protection - discover and apply complex theory to multiple scenarios.

The course integrates the content provided by the courses Smart Maintenance Management (SMM, 5 credits ) and Industrial Asset Management (IAM, 5 credits ); as a whole, it is delivered as Smart Maintenance and Industrial Asset Management (SM&IAM, 10 credits ). The goal of the SMM course ( first half of the semester ) is to introduce the student to a modern maintenance practice and advanced solutions for increased productivity, today vital for companies in every sector. The maintenance is indeed experiencing a radical evolution, moving towards an advanced management of the physical assets in order to guarantee the reliability, availability, efficiency, quality, safety, costs and sustainability in the operations of the physical assets and systems. The course will particularly address this evolution in the context of industrial plants in discrete manufacturing and process industry. The goal of the IAM course ( second half of the semester ) is to introduce the student to Industrial Asset Management, intended as an integrated methodology to optimize the management of the physical assets along their lifecycle. Currently defined as “the coordinated activities of an organization to realize value from assets” (ISO 55000), Asset Management provides a major focus on the long-term strategic perspective, orchestrating decisions and activities in various asset lifecycle stages (including design, commissioning, maintenance, operation, decommissioning). This is becoming popular in the industrial world, where attention is given to the physical assets, equivalently referred to as industrial assets. The course will then address the evolution of the discipline in the management across different sectors, including manufacturing plants, fleets of assets, and infrastructures as exemplary cases of application. The SMM course fits into the overall program curriculum, pursuing some of the defined general learning goals and, in particular, contributing to the development of the following capabilities: Understand context, functions, processes, resources and decisions of industrial maintenance management, and their impacts in terms of asset-related performances, costs and risks; Identify trends, technologies and methodologies to support decision-making to manage maintenance based on data and evidences from field, while orienting to the strategic requirements due to operations of the industrial plants and the business needs; Design solutions for industrial maintenance management built on the smart application of an engineering approach to face problems and opportunities in a business and industrial environment. The IAM course fits into the overall program curriculum, pursuing some of the defined general learning goals and, in particular, contributing to the development of the following capabilities: Understand context, functions, processes, resources and decisions of industrial asset management, and their impacts in terms of asset-related performances, costs and risks; Identify trends, technologies and methodologies to support decision-making to manage the lifecycle of industrial assets, in light of the stakeholders’ requirements and objectives to balance performances, costs and risks; Design solutions for industrial asset management, to orient towards realizing a sustainable value from assets based on smart approaches to balance performances, costs and risks in a business and industrial environment. The SM&IAM course as a whole aims at providing knowledge and understanding, both considering theory and practical abilities, for what concern the asset-related decision making in the maintenance and the industrial asset management practice.
Students will learn contents and practices according to what defined in the leaning objectives. The learning is correspondingly organized considering the course delivery in SMM and IAM thematical areas. Smart Maintenance Management (SMM) The expected learning outcomes of the SMM course - first half of SM&IAM course, achievable through lectures and exercise/case study sessions, consist of knowledge of the criteria and methods to support decisions for industrial maintenance management, and of the practical abilities to analyze performances, costs and risks to support a smart maintenance decision-making. In particular, the course will allow students to achieve knowledge and practical abilities in order to: Understand the role of industrial maintenance management for what concerns its impacts in terms of reliability, availability, efficiency, quality, costs, and sustainability; Distinguish different contexts and requirements identified in specific problem settings, eventually being able to understand problems and opportunities in a given business and industrial environment and to formulate the goals in terms of performances, costs and risks addressed by the physical assets; Identify trends, technologies and methodologies to support decision-making to manage maintenance based on data and evidences from field, while orienting to the strategic requirements due to operations of the industrial plants and the business needs; Analyze the performances, costs and risks impacted by a smart management approach in industrial maintenance management, through the use of key enabling technologies with particular emphasis on data analytics; Design solutions for a smart management approach in industrial maintenance, considering contexts and requirements due to specific problem settings, while targeting performances and costs, and the requirements for risk mitigation. Building on the theory and through problem-solving in exercise/case study sessions, students will acquire the skills to formulate a judgment, meaning to distinguish specific problem settings, analyze the data sets provided with these settings, and subsequently design solutions for cost-effective decisions in maintenance management. Industrial Asset Management (IAM) The expected learning outcomes of the IAM course - second half of SM&IAM course, achievable through lectures and exercise/case study sessions, consist of knowledge of the criteria and methods to support decisions for industrial asset management, and of the practical abilities to analyze performances, costs and risks to support a smart decision-making in the asset lifecycle. In particular, the course will allow students to achieve knowledge and practical abilities in order to: Understand the role of industrial asset management for what concerns its impacts in terms of reliability, availability, efficiency, quality, costs, and sustainability; Distinguish different contexts and requirements identified in specific problem settings, eventually being able to understand problems and opportunities in a given business and industrial environment and to formulate the goals in terms of performances, costs and risks addressed by the physical assets; Identify trends, technologies and methodologies to support decision-making to manage the lifecycle of industrial assets, in light of the stakeholders’ requirements and objectives to balance performances, costs and risks; Analyze the performances, costs and risks impacted by a smart management approach in industrial asset management, through the use of key enabling technologies with particular emphasis on data analytics and simulation (including novel perspectives taken from virtualization of industrial assets also known as Digital Twins); Design solutions for industrial asset management, considering contexts and requirements due to specific problem settings, with the purpose to orient towards realizing a sustainable value from assets based on smart approaches to balance performances, costs and risks in a business and industrial environment. Building on the theory and through problem-solving in exercise/case study sessions, students will acquire the skills to formulate a judgment, meaning to distinguish specific problem settings, analyze the data sets provided with these settings, and subsequently design solutions for cost-effective decisions in asset lifecycle management.
Programma
The course contents are delivered through lectures and exercise/case study sessions, and invited speakers from different industrial settings. The course delivery is correspondingly organized in SMM and IAM thematical areas. Smart Maintenance Management (SMM) This thematical area focuses on maintenance and its evolution towards an advanced management of the physical assets in industrial contexts. The evolution builds on reliability and maintenance engineering approaches adopted in different industrial sectors (Total Productive Maintenance and Reliability Centred Maintenance), presented though methods and techniques oriented to the risks mitigation, performance improvement, and costs optimization and saving. Innovative aspects are also addressed, including the exploitation of diagnostic and prognostic technologies in advanced architectures due to the digitization and automation, and the adoption of new management concepts leading to a data-driven decision-making and an augmented intelligence to support the operators. Impacts of maintenance will be evaluated in terms of reliability, availability, efficiency, quality, and costs in the operations of the assets; impacts for sustainability will be also considered through sustainability-related Key Performance Indicators and maintenance practice for their improvement. The following topics are correspondingly presented and discussed during the course (SMM course - first half of SM&IAM course): Maintenance concepts evolution towards advanced management Basics of Reliability, Maintainability, Availability (RAM) analysis Maintenance policies and strategies Maintenance costs, maintenance policies and strategies, and costs optimization Maintenance impacts and contributions for sustainability Reliability and Maintenance Engineering approaches, methods, techniques and models Prognostics and Health Management for Condition Based and Predictive Maintenance programs Advanced maintenance management practice built on the Key enabling technologies due to digitalization and automation Industrial Asset Management (IAM) This thematical area focuses on the evolution of Asset Management, looking at the capabilities integrated within an industrial organization when Asset Management is adopted. These capabilities serve to achieve a systematic and coordinated practice in order to sustainably manage the organization’s physical assets, and their associated performances, risks and expenditures over the lifecycles, with the purpose of contributing to the achievement of the organizational strategic plan. To enable this practice, different methodologies, methods, tools and Key Performance Indicators (KPIs) are required to develop an integrated approach including Asset Performance Management, Total Cost of Ownership and Risk assessment of the assets in the built and industrial environment. Moreover, the management of resources for logistic support of the physical assets and systems (including materials management and maintenance services) are considered as key lever for the sustainable management. Eventually, the use of the key enabling technologies due to the digitalization is discussed, presenting the information management along the asset life cycle, and including management and engineering tools specifically adopted for Asset Management. The following topics are correspondingly presented and discussed during the course (IAM course - second half of SM&IAM course): Industrial asset management and its evolution towards advanced management Asset Management system and its integration in the industrial organization Reliability and Maintenance Engineering approaches, methods, techniques and models Asset performance management (APM): i) methodologies, methods and tools for APM from individual asset-level to system-level assessment; ii) key performance indicators for APM from individual asset-level to system-level assessment (Overall Equipment, Line and Factory Effectiveness) Cost and risk assessment of physical assets (including Total cost of ownership, Performance-driven Total cost of ownership, Asset criticality assessment) Management of the resources required for logistic support of physical assets: MRO (maintenance, repair and operations) materials management and maintenance services Industrial asset management practice in different industries Information management along the asset life cycle, Key enabling technologies and tools

Obiettivo del corso è di introdurre a una pratica di manutenzione moderna e a soluzioni avanzate per una migliore produttività, oggi vitale per aziende in ogni settore. In particolare, l'evoluzione radicale verso una gestione avanzata degli asset fisici può ridefinire completamente il ruolo della manutenzione, che può diventare una funzione chiave di un più complesso e integrato concetto gestionale lungo il ciclo di vita degli asset. Il ruolo della manutenzione nella gestione del ciclo di vita degli asset è quindi considerato come un fattore decisivo per: ridurre i costi; ottimizzare il servizio fornito dagli asset; garantire la sicurezza, qualità, affidabilità e disponibilità; massimizzare il valore ottenuto dall'uso degli asset, contribuendo infine alla competitività dell'azienda. Questa evoluzione beneficia dello sviluppo di nuovi concetti di manutenzione capaci di sfruttare: i) le tecnologie avanzate dell'informazione, della comunicazione e dell'automazione di impianto; ii) le nuove tecnologie diagnostiche e prognostiche per valutare e predire lo stato di salute degli asset; iii) i nuovi concetti manageriali, i cui fondamenti sono un processo decisionale basato sui dati e il ruolo del capitale umano come risorsa supportata da intelligenza aumentata disponibile da un supporto tecnologico avanzato.

L'esame riguarda gli argomenti sviluppati durante le lezioni, le esercitazioni e i seminari tenuti da docenti invitati. Inoltre, durante la prova potranno essere richiesti approfondimenti relativi a specifici aspetti o applicazioni dei concetti trattati, anche attraverso la discussione di casi analoghi a quelli affrontati durante il corso. In particolare: Prima parte: 10 quesiti a risposta multipla. Punteggio minimo per l'accesso alla seconda parte: 7/10 (+1 risposta corretta, 0 risposta non data, −0,5 risposta errata). Seconda parte: domande a risposta aperta. Il voto della prova scritta corrisponde al 50% della valutazione finale. Il progetto, sviluppato durante il semestre, sarà valutato sia in itinere sia al termine delle attività e contribuirà per il restante 50% alla valutazione finale. La valutazione è finalizzata a verificare il raggiungimento dei risultati di apprendimento attesi, in coerenza con i Descrittori di Dublino. In particolare: la prova scritta verifica l'acquisizione delle conoscenze e della comprensione dei biomateriali, delle tecnologie di biofabrication, dei metodi di caratterizzazione e degli approcci propri della Medicina Rigenerativa e dell'Ingegneria dei Tessuti (DdD 1 – Conoscenza e comprensione); il progetto valuta la capacità di applicare le conoscenze acquisite alla progettazione e allo sviluppo di scaffold, sistemi di rilascio di farmaci e cellule e modelli tridimensionali in vitro per specifiche applicazioni biomedicali (DdD 2 – Capacità di applicare conoscenza e comprensione); la valutazione complessiva, attraverso la prova scritta, il progetto e la relativa discussione, verifica la capacità dello studente di analizzare criticamente le soluzioni proposte, motivare le scelte progettuali sulla base di criteri scientifici e ingegneristici, comunicare efficacemente utilizzando un linguaggio tecnico-scientifico appropriato e operare in gruppo sviluppando autonomia di giudizio e capacità di apprendimento (DdD 3 – Autonomia di giudizio, DdD 4 – Abilità comunicative e DdD 5 – Capacità di apprendimento). Ai fini della determinazione del voto finale saranno presi in considerazione i seguenti elementi: conoscenza e comprensione degli argomenti trattati; capacità di analisi critica e di collegamento tra i diversi contenuti del corso; capacità di applicare le conoscenze acquisite alla discussione di casi e problematiche specifiche; correttezza e appropriatezza del linguaggio tecnico-scientifico utilizzato; autonomia di giudizio e capacità di motivare le scelte progettuali; qualità del progetto sviluppato, inclusa la capacità di organizzare il lavoro e collaborare efficacemente all'interno del gruppo. The assessment consists of a 75-minute written examination covering the entire course syllabus. The examination is divided into two parts. Students are required to answer multiple-choice and open-ended questions addressing the fundamental concepts covered during the course, using appropriate scientific terminology and engineering formalism. The examination covers the topics presented during the lectures, tutorial sessions, and seminars delivered by invited speakers. In addition, students may be asked to further discuss specific aspects or applications of the concepts covered, including the analysis of case studies similar to those addressed during the course. Specifically: Part I: 10 multiple-choice questions. The minimum score required to access Part II is 7/10 (+1 for each correct answer, 0 for unanswered questions, −0.5 for incorrect answers). Part II: open-ended questions. The written examination accounts for 50% of the final grade. The project, developed throughout the semester, will be assessed both during its development and at the end of the course and will contribute the remaining 50% of the final grade. The assessment is designed to verify the achievement of the intended learning outcomes in accordance with the Dublin Descriptors. In particular: the written examination assesses the acquisition of knowledge and understanding of biomaterials, biofabrication technologies, characterization methods, and the fundamental principles of Regenerative Medicine and Tissue Engineering (DdD 1 – Knowledge and Understanding); the project evaluates the ability to apply the acquired knowledge to the design and development of scaffolds, controlled drug and cell delivery systems, and three-dimensional in vitro models for specific biomedical applications (DdD 2 – Applying Knowledge and Understanding); the overall assessment, including the written examination, the project, and its discussion, evaluates the student's ability to critically analyze proposed solutions, justify design choices based on scientific and engineering principles, communicate technical concepts effectively using appropriate scientific terminology, and work collaboratively while demonstrating independent judgment and lifelong learning skills (DdD 3 – Making Judgements, DdD 4 – Communication Skills, and DdD 5 – Learning Skills). The final grade will be determined by considering the following criteria: knowledge and understanding of the course topics; ability to critically analyze and integrate the different course contents; ability to apply the acquired knowledge to the discussion of specific case studies and engineering problems; correctness and appropriate use of scientific and technical terminology; independent judgment and ability to justify design choices; quality of the project, including the ability to organize the work effectively and collaborate within a team.

Le politiche per la mobilità sostenibile e per la decarbonizzazione dei trasporti sono tipicamente orientate all'offerta, ovvero alla progettazione di infrastrutture e veicoli più performanti, e servizi più attraenti per il viaggiatore. Questo corso approfondisce quelle politiche della mobilità indirizzate alla sostenibilità dei comportamenti di viaggio attraverso l'interazione e la responsabilizzazione degli individui, nonché la spinta ("nudge") verso comportamenti di mobilità più sostenibili. Gli studenti apprendono le conoscenze teoriche per la modellazione dei comportamenti di viaggio degli individui (discrete choice analysis) e gli strumenti per la stima di modelli avanzati e la progettazione di indagini di mobilità. Vengono presentati, inoltre, casi d'uso finalizzati al corretto dimensionamento di infrastrutture e servizi di trasporto, tenendo conto della percezione individuale dell'ambiente costruito e della risposta comportamentale ("user acceptance") all'introduzione di tecnologie avanzate (ad es. veicoli a guida autonoma, servizi di urban air mobility). Per ogni argomento vengono svolte esercitazioni e presentati casi di studio recenti.

This course aims at introducing the main principles and methods of Swarm Intelligence. More precisely, the course will focus on methodologies for controlling and, more importantly, coordinating large-scale robotics systems, within the research field most commonly known as swarm robotics. Swarm robotics is an approach to robotics that has its roots in the observation of natural systems, most commonly social insects, which are known to solve problems collectively that otherwise cannot be tackled by single individuals. Robots in a swarm must operate and coordinate their action without relying on any form of global information: they only rely on local sensing and communication. The main driving principle leading to useful collective behaviours in a swarm is self-organization, that must be guided in the desired direction using engineering tools. As the discipline is relatively new, only small steps have been made towards formalizing engineering tools. This course introduces the student to state of the art methods for the control and coordination of large swarms of robots. The course will be highly project driven and the students will be encouraged to work on projects that are at the frontier of what is known and can be done in the field. The project may involve coding of control and coordination methods for large swarms, coding of learning, evolution, and adaptation algorithms for designing for specific scenarios, validation of experiments on low fidelity and high fidelity simulation environments, and relevant validation on real robot platforms.
1 - Knowledge and Understanding In terms of acquired knowledge and understanding, students will be able to: Understand the main design constraints of swarm robotics and be able to map them into real world settings Obtain an overview of the different stages of technology readiness related to swarm robotics systems, and the current boundaries in technological capabilities Be able to classify swarm robotics capabilities into building blocks (collective behaviours), and for each building block understand the minimum hardware capability required to realize it Understand the main methodologies developed in the field to manually design individual-level controllers (e.g. finite state machines, virtual potential functions, etc …) Understand the main methodologies developed in the field to design individual-level controllers using automated design methods (evolutionary robotics and other design methods) Understand the mathematical frameworks used to model collective behaviours and to predict their outcome in idealized conditions 2 - Applying Knowledge and Understanding Concerning the ability to apply the acquired knowledge and understanding, students will be able to: Be able to select and formulate a relevant research question within the field Be able to identify a real world problem and to design a solution for the problem using swarm robotics technologies Select and derive an appropriate swarm robotics methodology for a problem and describe it in terms of the relevant mathematical formalism Implement selected simulation environments to study the research question or solve the real world problem Implement the control and coordination methodology using a selected programming language within the given simulation environment Perform experiments in simulation, define, implement and collect metrics, analyze the result If applicable, implement relevant hardware components for real world validation Perform experiments in real world, collect metrics, analyze the results Present the finding of the project in classroom 3 - Making Judgment Regarding the ability to make judgments, the students will be able to: Critically evaluate the published literature in the swarm robotics field using a multidisciplinary approach to identify novel research problems Judge the level of maturity of different technologies and their potential suitability to contribute as building blocks for swarm robotics solutions In developing a control and coordination method, be able to infer as early as possible the implications in terms of the required technology for porting the method in real life Understand the challenges of the reality gap and be able to make relevant assumptions in terms of robot capabilities and coordination strategies Be able to understand data produced by metrics on the macroscopic collective behaviour of the swarm, and be able to link it to root causes and factor at the individual control and coordination level Understand the limit of the work done and be able to identify future lines of research and development
Programma
A brief outline covering the course topics is the following: Introduction to swarm robotics: Definition of the field Communication modalities in a swarm Example of robots in swarm robotics Example of open research topics in the field. Dual goal: science vs engineering Taxonomies used in the field: collective behaviours versus design and analysis methods Collective behaviours: Spatially organizing behaviours (aggregation, morphogenesis, …) Navigation behaviours (collective motion, exploration, …) Collective decision making (best of n, task allocation) Other types of collective behaviours Design methodologies: Manual/behaviour-based design (Probabilistic Finite State Machines, Virtual potential functions, …) Automatic design methodologies (Evolutionary Swarm Robotics, AutoMoDe, …) Analysis methodologies: Macroscopic models (Ordinary Differential Equations, Stochastic Differential Equations, control theory) Microscopic models (review of simulation and different levels of realism) Current research trends in swarm robotics Software used: Open-source software for multi-robot system simulation (e.g., low-fidelity Python tools, ARGoS, Gazebo, etc.). Matlab and other math software may be chosen and utilized as well.
Modalità d'esame
Progetto/i - Elaborato/i obbligatorio, di gruppo, con revisioni periodiche, con presentazione/discussione finale The course is divided into a series of lessons and practical sessions. The main modalities of evaluation will be oral exam (presentation) and a written report. More precisely, the students will be divided into groups of 2 to 4 students (depending on the total number of registered students). They will work on a single long project across the semester. Each group will work on a selected project covering a subset of course topics, meaning not all aspects of swarm robotics will be covered in every project. However, the oral exam may include short questions on broader course content beyond the selected project. The project will be divided into phases, and each phase will terminate in a group presentation (oral exam). In this oral exam: 1) the students will prepare a powerpoint presentation on the specific phase of the project 2) the student will discuss the presentation publicly during the oral exam. 3) during the oral exam, the student will also answer questions, in open form, that focus on the content of the presentation and of the project, but can also expand to all topics covered in the course. The students may accompany the answers with equations, graphs, sketches, in a synthetic and complete exposition. The oral test will assess the following elements (each in a relevant phase): the ability of the students to work in group the ability to meaningfully formulate valid swarm robotics research questions or identify a valid real world problem the ability to derive and appropriately describe a methodology for the problem, in a correct and clear mathematical formalism, that may or may not go beyond the state of the art presented in the classroom the ability to perform experiments in simulation and in real world the ability to present results with high quality graphical representations the ability to criticize results and to identify future directions the ability to connect the performed work with the broader topics of the course At the end of the semester, each group of students will present a short report in the form of a scientific paper describing the entire project. The final grade will combine the grades of the individual phase presentations (oral exam) and of the report. Slides of the lessons, which include all the topics of the course, are provided via WeBeeP.

We are in the era of large, decentralized, distributed environments where the amount of devices and data, and their heterogeneity, is getting out of control. Organizations capture billions of bytes of data about their activities, users, operators, customers and suppliers, but their ability to collect, manage and interpret this information could be an obstacle to its use. The web is widening the range of data providers and consumers. Sensors, mobile devices, and, in general, the IoT generate additional data that needs to be integrated and harmonized with the rest to create value. Decision-making is based on information, not just on data. More accurate information leads to better decisions and provides competitive advantages; hence processing, manipulating, and organizing data in a way that adds new knowledge has become a necessary issue. The goal of the course is to enable students to master the engineering methods and processes that are necessary to manage modern information systems, and especially data-intensive systems, to operate on large data collections, and to understand the utility and methods of data analytics (i.e., business analysis and machine learning algorithms), obtaining useful knowledge to improve decision-making processes. As a consequence, we expose the students to some of the most advanced methodologies adopted to understand the conceptual and technological problems encountered in the design and implementation of "data products": tangible results based on analyses for complex systems, concentrating, as raw material, on collections of data that must be integrated, organized and analyzed mainly through automatic tools. In the belief that understanding is boosted by communication, this course is “Communication-Intensive”, in the sense that it aims at enhancing the students’ communication skills as applied to the technical content of the course, with a special emphasis on clarity and common ground (i.e. being able to take the interlocutors’ body of knowledge into proper account).
Dublin Descriptors Expected learning outcomes 1. Knowledge and understanding The students will learn how to: Identify the phases of Big Data management, from the choice of the data sources to the production of a “data product” Analyze the data sources and design a data integration system Design a data warehouse Identify the data quality problems encountered when managing heterogeneous collections of data 2. Applying knowledge and understanding Given specific project cases, students will be able to: Detail the corresponding requirements Analyze and comment on specific conceptual and architectural choices Apply the theory to decide the most appropriate ones Develop data integration and data warehouse solutions fulfilling the high-level and design specifications. 3. Making judgements Given a relatively complex problem, students will be able to: Analyze and understand the goals, assumptions and requirements associated with that problem and model them Define the type of architecture of the corresponding system Identify the appropriate conceptual and logical design methodology Estimate the system and the resources needed for its development 4. Communication The students will learn to clearly explain a technological or methodological issue at the correct level of abstraction, considering the common ground with the interlocutor. 5. Lifelong learning skills The students will learn how to develop a realistic data product
Programma
Information System Architectures and Heterogeneous Data Integration: structured and non-structured data: Introduction to the architectures of modern information systems Basics of Data Integration: model heterogeneity, semantic heterogeneity at the schema level, heterogeneity at the data level Dynamic and lightweight data integration: the use of wrappers, mediators, meta-models, ontologies, etc The future of data integration Data Quality Data Warehousing: Data Warehouse Architecture and querying Data Warehouse Conceptual Design Data Warehouse Logical Design New research trends Communication Skills Basic elements of Communication Sciences (how to be clear) Common-ground Theory Writing skills NOTES:
The bibliography includes useful references and is by no means exhaustive of the topics covered in the course. More readings will be mentioned during the lectures. The students are advised to attend the lectures, ask the professor for explanations and read the articles. For each of the books, only the part included in the lectures is mandatory.
Modalità d'esame
Prova scritta obbligatoria, senza prove in itinere The assessment will be based on a written exam and a homework communication assignment. The exam is considered as passed if both parts have been passed. If the student does not pass one of these two parts in the same exam call, the mark of the passed part will be saved; in a future call, the student will need to retake only the failed part. The written exam consists of (i) an exercise/design part, consisting in the design of an integration system or of a data warehouse; (ii) a theoretical part, in which the students will be asked to explain clearly, in their own words, two of the subjects illustrated during the lectures. The scores of the two written parts will be summed up to compute the total score. Students can take the written part at any exam session during the same academic year. The homework communication assignment requires the students to summarize a technical text, having in mind a non-technical reader. The assignment will be evaluated by the communication instructor. The evaluation will be “pass/non-pass”; in case of excellence, one additional point will be assigned to the student in the overall score of the exam. The following table provides a detailed overview of the elements that will be considered in the various assessment activities. Type of assessment Description Dublin descriptor Written test Exercises focusing on design aspects: Design of a data integration system based on the requirements provided or Design of a data warehouse based on the requirements provided Three theoretical questions on the course topics Communication assignment: summarization of a research paper in words understandable by a non-technical reader. 1,2,3,5 1, 2, 3, 4, 5

Obiettivi formativi
The course aims at introducing the optimal design of complex systems with reference to ground vehicles from a multidisciplinary perspective. Multi-objective optimisation, Artificial Intelligence approaches and Robust Design methods are introduced. The methods are applied to optimise designs mostly related to ground vehicles. The optimal design of structural elements, the concept design of vehicles, the vehicle suspension design, the integration of electronically controlled systems will be discussed.
By the end of the course, students will learn contents and practices according to what defined in the leaning objectives. In terms of acquired knowledge and understanding, students will be able to:
define the design requirements
correctly formulate an optimisation problem, in both single and multi-objective frameworks
select the most effective numerical procedures for solving a given optimisation problem
analyse the results and select a final design solution. The projects will allow the students to
perform preliminary design
optimally design vehicles subsystems
deal with lightweight design problems
summarize and present the results. Concerning the ability to apply the acquired knowledge and understanding, students will be able to -complete the design of a vehicle subsystem -apply multi-objective optimization to find optimal solutions for the vehicle subsystems with respect to a given vehicle mission. Through projects, the students will also acquire the skills to formulate a judgment, meaning to define a technical specification, find autonomously the problem input data, apply proper optimization techniques, perform a critical analysis of the obtained results and explain them. They will also acquire the ability to discuss in a team the proposed design. Furthermore, through the assigned case studies, students will gain the ability to autonomously
define models of different complexity, with the objective of obtaining a suitable trade off between the accuracy of the solution and required computational cost
evaluate the benefits of design optimisation and propose new solutions
use the appropriate supervised learning techniques (AI)
critically discuss their project and propose improvements that they assume necessary to limit the effect of the simplifications introduced for reducing the computational effort. Finally, students will improve their communication skills, being able to write reports presenting the developed projects. In particular, the students are requested to prepare their reports addressing the following issues
define a design specification
describe the theoretical background of the applied methods
explain the assumptions, approximations introduced and their impact on the results
show the relevant results
highlight the impact of the optimisation methods learned in the course on the final design, with respect to a traditional design approach.

Obiettivi formativi
The course aims to introduce basic and advanced concepts necessary for understanding the structure-property correlations of polymeric materials and composites for engineering applications. The analysis is carried out starting from the linear behavior (liquid and solid state) and time dependent (viscoelasticity) and then passing to the durability examination intended as the beginning of irreversible phenomena that lead to the degradation of the structure and performance of materials. They include the yield, fracture and phenomena of change of the chemical structure (eg degradation by exposure to sunlight) and physics of materials.
The student:
knows and understands the structure-property correlations of polymers and composites and their appropriate use in the design of processes and products for Materials Engineering and Nanotechnologies (DdD1);
knows how to make choices related to the dimensioning of components and the use of materials in relation to the specific use of the product (DdD1-DdD2);
autonomously carries out insights on topics related to the course to solve simple design problems (DdD2). The project-work also has the objective of stimulating the student's ability to develop autonomous knowledge of the subject, to address and critically discuss problems and situations also other than those faced during the lessons, and to make design choices. These abilities will be taken into account in the final evaluation.

Obiettivi formativi
Motivated by the increasing penetration of distributed energy resources (DERs) and the structuring of the electrical grid into multiple microgrids that enable the provision of new smart grid services, the goal of this course is to introduce students to strategies for the optimal coordination and control of complex systems coping with aspects like a multi-agent large scale structure, the presence of uncertainty affecting the system and of integer decision variables, and the need to guarantee privacy of local information.
The students will get some insight into the electrical grid evolution and learn methods for modeling typical energy management problems and mastering their complexity through optimization-based approaches for the operation of multi-agent possibly uncertain systems (DdD1 - Knowledge and understanding). Through the project work, they will not only apply the acquired knowledge (DdD2 - Capability to apply knowledge and understanding) but also improve their autonomy and critical thinking (DdD3 - Making judgements), their team working and communication skills (DdD4 - Communication skills), and their capability of devising ad-hoc solutions to the problem at hand (DdD5 - Learning skills).
Programma
1. Introduction to the electrical grid system and to the challenges and opportunities offered by its current evolution towards the smart grid concept. In particular, electrical energy production from traditional and renewable sources will be considered, as well as requirements in various use cases and scenarios, role of non-programmable sources and impact on the network infrastructure, with a special focus on technological trends and developments of DERs and microgrids, including storage, electric vehicles, and ICT technologies. 2. Description of some relevant case studies for the optimal management of the electrical grid that can be formulated in terms of constrained optimization problems possibly involving multiple agents and affected by uncertainty, calling for distributed and data-driven resolution approaches. In particular, we shall consider the provision of ancillary services to the grid by the aggregation of multiple prosumers, the scheduling of the charging of a fleet of electric vehicles, and the energy management of a building district. 3. Motivated by the above case studies, we shall present relevant algorithms for solving multi-agent convex optimization problems with coupling due to shared decision variables or resources (the distributed dual subgradient and alternating direction method of multipliers algorithms), and discuss their extension to address the case when integer variables and uncertainty known only from data are present.
Modalità d'esame

an oral exam on the content of the course (DdD1, DdD4);

The group will give a 20 minutes oral presentation (slides) concerning the HAWT design exercises. All group members should present a part of the project. Each WG should produce "a brief original part (5 minutes)" independently choosen. The examination board will ask questions concerning the project (methods and outcomes) and all related theoretical contents. At the end of the exam the examination board will assign an individual grade to each working group member. A second part is based on a Technical Report prepared by the WG, describing the assigned VAWT project and performance analysis. A single evaluation will be given to all students of the same WG. The report should be provided before the HAWT presentation. The third part of the exam is a written exam that can be given by each student independently formn the WG. It will be composed by 2 questions concerning all course contents (theoretical contents and design exercises). The grade of the written exam can be rejected and the third part repeated. The final grade will be based on a weighted average of the grades obtained in the three parts of the exam. Details on the averaging procedure will be given during the first lecture. It the final grade will be rejected by the student, the repetition of the exam will be based on a oral exam on all course contents and design exercises.

L'obiettivo principale di questo corso è fornire una valutazione quantitativa delle maggiori sfide ambientali e delle loro ripercussioni sul funzionamento dei sistemi economici e umani. Un focus particolare sarà dato a due sfide ambientali globali che rappresentano due tra i maggiori rischi affrontati dalle nostre società: il cambiamento climatico e l'inquinamento atmosferico. Il corso presenta il loro impatto su diverse sfere economico-sociali e individuerà politiche e soluzioni per mitigare la loro influenza, dal punto di vista dei governi, delle aziende private e dei cittadini. Il focus geografico sarà globale, analizzando sia le economie industrializzate che i paesi in via di sviluppo. Il corso mira anche a trasmettere metodologie di econometria e data science per analizzare le relazioni causali tra le sfide ambientali globali e gli esiti socio-economici. Durante il corso, gli studenti impareranno l'applicazione di metodi sperimentali (ovvero studi randomizzati controllati) e non sperimentali (Dif-in-Dif, dati panel, Regression Discontinuity Design) per la valutazione dell'impatto. Si discuterà anche di come i big data provenienti da sensori intelligenti, osservazioni satellitari, ecc. possano aiutare a identificare le cause del cambiamento ambientale globale e mitigare il loro impatto. Ciò avverrà principalmente attraverso la presentazione di articoli accademici e casi di studio e lavori di gruppo applicati.

Programma
Topics Covered Amazon, Apple, McDonald's, Procter and Gamble (P&G), Unilever. What do they have in common? Most of them share outstanding places in Fortune 500 ranking, and all of them – according to Gartner [1] – represent the Masters category, which recognizes sustained SC excellence. The Masters continue to demonstrate advanced lessons for the SC community, and they highlight the accomplishments and capabilities of long-term SC leadership. While the wave of Covid pandemic was sweeping the world, SC disruptions and resilience gained attention in daily news. However, behind resilience and agility – to navigate turmoil effectively and successfully – SC Masters have been restructuring their organizations, transforming business models and redefining markets by blending well-established capabilities with emerging innovations. In the end, SC masters have succeeded in reshaping their own SCs through tremendously effective planning initiatives. How should we care about SC planning? In a search for competitive differential advantage, many managers of world–class organizations around the globe have come to realize that differentiating on processes is more sustainable than differentiating on products. Indeed, SC planning is the forward-looking process of coordinating assets to optimize the delivery of goods, services and information from supplier to customer, balancing supply and demand [2]. SC planning looks after current processes – including the ones originated in pure service industries – and determine methods for orchestrating the execution flow, the information flow and the financial flow in SCs. Who are SC planners? SC planners have the ability to look at the whole SC from upstream to downstream with both short- and long-term mindset. They also troubleshoot breakdowns along the SC and respond fluidly to unexpected events. We now live in the age of the digital SC, which makes it easier than ever before to understand the intricacies of SCs. SC planners are tech-savvy and they feel comfortable working alongside the world of “machines”: they combine technical and business knowledge (for example the ability to handle forecasting and logistics) with collaboration and communication skills in writing and verbal conversation with a wide range of characters from dock workers to high-level executives and business owners. SC planners do not work in a silo and they do not wait for someone else to do what needs to be done. They are proactive, and they bring out the same drive in others. In the end, SC planners are leaders in the seminal meaning of people who cause others to want to travel with them [3]: they show the way to themselves, to others and to teams. How should we train the SC planners of the future? When it comes to SC planning, CEOs typically feel in the dark and they take a back seat, thus overlooking that if an organization really nails its SC planning, it can react to disruptions before they even happen, and quickly transform strategy into execution. We must train SC planners in such a way that they are able to steer their organizations to respond more quickly to market development, and they can lead their organizations on a journey toward prolonged success by forging a greater synergy with their CEOs. There are at least three major topics SC planners should make their CEOs aware of, before dipping their toes into SC planning: (i) whether company’s SC has been consciously established and improved through a decision-making process, or it has merely evolved, which reveals that probably SC configuration has not received enough attention and your logistics managers do not know why warehouses are located where they are; (ii) whether business and SC strategies are misaligned, as SC plans have much more to do with customers and service than suppliers and cost, which means that a growth business strategy and an aggressive cost-cutting SC strategy do not match; (iii) whether some customers are over-serviced – and then less profitable – as service levels are based on perceived customer needs, but you failed to check whether the reality matches that perception. What SC planners should bring in their toolboxes? Some widespread gossip whispers that SC planners are ideal positions for analytical nerds who spend their idle time at work playing Tetris and who would rather solve a Rubik’s cube at the weekend than do anything else. On the other hand, the SC planners of the future are outgoing leaders with outstanding ability to steer effective SC designs: they keep SC plans aligned to business plans, and they improve service levels while reducing costs at once. Hence, a typical SC planning toolbox include: Sales and Operations Planning (S&OP), Collaborative Planning Forecasting and Replenishment (CPFR), Vendor–Managed Inventory (VMI), Direct Delivery Systems (DDS), Available and Capable to Promise (ATP/CTP), multi-plant capacity planning, demand and inventory planning and factory planning. Syllabus To properly match the requirements of both Management Engineering (ME) and Management of Built Environment (MBE) courses of study, classes have been arranged into 14 main sessions with a typical format of 3 – 4 hours in a row once a week (typically on Monday morning). The course syllabus has been built around the best path we should set out to properly train the SC planners of the future. Students will be confronted with various real-life, real-time dilemmas that require cross-functional understanding, collaboration, and leadership. Sessions L1 to L11 are related to lectures and each of them matches with several case studies, to be practiced in the corresponding session in a flipped mode fashion. Case-studies play a pivotal role in achieving a relevant portion of learning objectives [1], and they will be corroborated by some guest speeches of industrial directors and planners. The introductory session (L1) is devoted to SCs and SC planning and the presentation of SCOR model (Source, Make, Deliver and Return), while Sessions L2-L4 refer to sustainable, strategic and global SC configuration. L5 refers to the evolution of S&OP through IBP. Then, Session L6 is related to emerging trends and recent advances in make vs. buy SC strategy and the role of SC finance supporting decisions of corporate strategy. Session L7 is releted to risk mitigation strategies aimed at making SCs resilient to economic and geopolitical disruptions. Session L8 and L9 focus on the impact of customer service and marketing strategies on SC planning process. Session L10 addresses the role of “x”-shoring strategies (like re-, back-, near-) as a response to economic and geopolitical risks.Session L11 outlines the impact of product design on SCs and the interactions between NPD process ad SC management process. Finally, sessions T1 and T2 include additional practice respectively on sessions L1-L6 and L7-L11, and (upon request) they can be graded as Mid-term exam and Early-bird exam. The course in a nutshell L1 Execution, information and financial planning. SCOR model L2 Strategic SC planning in action: Fisher & Hau Lee Models L3 Using AI for SC planning L4 Integrating SC planning and marketing L5 Global SC planning & distribution networks L6 SC planning via IBP L7 S&OP Game L8 Upsteam SC planning & SC finance L9 Sustainabile SC planning for circular economy L10 Mitigating SC risks and creating resilience L11 Aligning SC planning and NPD process [1] To see how a typical case-based session should look like, try: https://www.youtube.com/watch?v=p7iwXvBnbIE.

Modalità d'esame
Prova scritta facoltativa (a scelta dello studente), con prove in itinere Prova orale facoltativa (a scelta dello studente) Valutazione continua facoltativa (a scelta dello studente) Grading All assignments are due by 11:59 PM CET on the due date, usually the day before the corresponding session. For example, when a session is scheduled on Friday, assignments are due by Wednesday at midnight. When a session is scheduled on Monday, assignments are due by Thursday at midnight To accomplish our learning objectives, we use a variety of techniques: readings, written assignments, videos, and discussion. We will often refer to and apply the tools and frameworks from the class when analyzing cases, discussing issues, and treating SC planning problems. One of the real benefits of the course is that you can enhance your learning through productive discussion with peers in the classroom. Contributions are evaluated on the basis on your willingness to constructively challenge and discuss the concepts of SC planning through presentations, case assignments and in-class exercises. Case discussions are useful as you are supposed to put yourself in the shoes of the executives and take a position on what you would do. Questions have been provided that lead you through important issues to examine. For every question, always consider the pros and cons of each answer, as there are no easy solutions in SC planning. Considering both sides will push you to reconsider the assumptions that often are embedded in each problem setting. Another important part of case analysis is to look at any numerical information provided. The numbers can and should guide you towards both the successes and failures of the company. This portion of the class may involve breakout sessions for teams to generate strategies and tactics from individual analysis for class discussion. Whenever you provide an assessment, try to frame your thinking about the criteria of interest. My experience taught me that disagreements arise since the basis for the decision was predicated on different criteria and therefore agreement became impossible. Being articulate about criteria allows you to speak with each other rather than past each other. Class participation is scored as a function of the quality of your contributions (i.e. does your comment move the class discussion forward) rather than the quantity of comments. Students are encouraged to refrain from prolonged or misdirected monologues, statements of common knowledge, and confrontations that are not directed at the issue at hand. The table below summarizes all assignments along with the corresponding grade points. Any item missing will be treated via an oral test taken after the end of the course, by absorbing the corresponding weight.

This course is designed to equip students with the concepts and tools of sustainability and impact management in a world increasingly shaped by complex and interdependent challenges. In this evolving context, economic actors are rethinking their strategies, operations, and impact in response to sustainability imperatives that can no longer be addressed through traditional approaches alone. Students will develop radical management mindset and capabilities to engage with the enabling infrastructures, such as regulatory frameworks, measurement systems, technology, and finance mechanisms, that support and guide sustainable transformations. The course provides an updated lens to reinterpret core managerial concepts, including strategy, technology management, finance, and performance measurement, within the context of impact-driven business models and emerging economic paradigms. The course explores evolving market dynamics, corporate models, and entrepreneurial approaches explicitly designed to tackle societal issues while generating positive impact. Through a combination of theoretical insights, case studies, and practical tools, students will learn how strategy, innovation, finance, and impact management systems can be reshaped to serve both social purpose ventures and mainstream organizations committed to sustainability. By the end of the course, students will be able to interpret the complex and systemic interrelations among societal challenges, technological innovation, market disruptions, and purpose-driven corporate and entrepreneurial models. In particular, the course contributes to the development of the following capabilities: Understanding the concept of impact and sustainability management and the foundations of purpose-driven corporate and entrepreneurial models. The distinguishing feature of such models is the proactive pursuit of solutions to societal problems along with economic sustainability and profit. Designing innovative solutions through the application of scientific approaches (Analysis, Learning, Reasoning, and Modeling capability deriving from a solid and rigorous multidisciplinary background) to face societal challenges and seizing related opportunities, developing system-changing ideas, scaling solutions and translating them into long-term oriented, sustainable business models; Interpreting real-world situations and learning from case studies; Interacting in a professional, responsible, effective and constructive way in a working environment, also motivating group members.
On completion of the course, students will be able to: Understand the concept of impact and sustainability management, and how purpose-driven corporate and entrepreneurial models respond to emerging societal challenges and opportunities within the impact economy. Grasp the foundations and real-world applications of impact and sustainability management as a key driver of systemic transformation. Reinterpret core managerial notions, such as strategy, technology, performance measurement, and finance, through the lens of purpose, sustainability and impact. Design innovative, impact-oriented business models for ventures addressing societal challenges, and develop coherent management strategies. Apply managerial tools and develop competencies to face the specific challenges that characterize organizations committed to tackling societal issues. Understand the role of technology as an enabler of systemic change and as a strategic asset in sustainability-driven transformation. Use frameworks and tools to measure and manage organizational performance in relation to societal impacts. Analyze and compare financial instruments and approaches that aim to generate measurable societal impact alongside financial returns. Learn how to scale ventures oriented toward societal impact by leveraging ESG criteria, impact finance, and hybrid growth strategies. Communicate ideas and concepts effectively in both oral and written form, through case study discussions, presentations, and assessments.

The course develops knowledge and skills for the advanced modelling, management, and control of natural resources systems. The emphasis is on the operational and real time control aspects of natural resources modeling and management, with a focus on water resources systems and extensive reference to real world case studies. Topics include: natural resources systems modeling for management (from stochastic processes, through linear models, to non-linear model and machine learning), predictive modelling, uncertainty and sensitivity analysis, model diagnostics, stochastic and robust optimal control, approximate control methods (e.g. simulation-based approaches, approximate dynamic programming, reinforcement learning), real time control, and complexity reduction methods. The course is organized into two modules: the 1st module develops topics from data to well validated models, the 2nd covers algorithms and methods to design optimal decisions and negotiation support systems. The course is aimed at graduate students preparing to work in environmental and water resources engineering field.
The expected learning outcomes are defined according to the Dublin Descriptors, outlining the competencies that students will develop in terms of theoretical knowledge, practical skills, independent judgment, communication abilities, and learning capacity: Knowledge and understanding Students will acquire the essential knowledge required to design and manage environmental systems planning projects in a participatory and inclusive way, considering institutional, regulatory, and physical contexts. They will also develop skills in the use of basic mathematical models and decision-support tools to address complex problems involving heterogeneous and often conflicting interests. Applying knowledge and understanding Through the development of real-world case studies, students will learn how to critically apply the tools and techniques acquired to practical contexts, translating theoretical concepts into practice and addressing typical challenges such as data scarcity and uncertainty, regulatory and institutional complexity, and technological constraints and opportunities (e.g. computational). Making judgments Students will develop the ability to critically analyze complex problems, distinguishing the rational and objective components of environmental decision-making from the subjective and behavioral aspects linked to stakeholders’ preferences, in order to provide well-founded assessments that effectively support negotiation processes. Communication skills Throughout the course, students will engage in project-based activities that involve the formulation and solution of real-world problems, as well as the clear, rigorous, and effective oral and written communication of results, adapting their communication to different audiences, including decision-makers. Learning skills By integrating lectures, laboratories, and project work, students will strengthen their ability to learn autonomously, keep up to date with new methodologies and tools, and proactively address evolving professional and research contexts.

The Course is meant to provide the basic knowledge related to the conversion of primary energy sources into electricity. In particular, large thermal power stations as well as renewables will be considered during the Course. Dealing with renewables, starting from hydro power stations, we will move to wind generation and solar generation (photovoltaic), also considering storage systems like pumped storage plants. According to the Dublin descriptors, the Course starts from theoretical basic knowledge to provide the ability to apply such knowledge and use it following a very practical approach and usually finds an obvious conclusion with a couple of technical visits at a thermal and a hydro power station; this will make it possible to become aware of the complexity in designing and operating power stations. A second goal is to teach the students the notation and terminology used in the field, quite often multidisciplinary (coming from hydraulic, mechanical, energy, etc. engineering) and not related to electricity, necessary to understand muti-physic problems, like those faced in real generation plants, and to understand and make use of technical standards (Communication skills and learning skills). The Course is divided into theoretical lectures, tutorials and projects. Projects, in particular, will be taught by engineers coming from industry, specialized in the considered fields. Four projects will be proposed to be developed by small groups and a report for each of them will have to be handed in.
Students, at the end of the course, will be able to: 1) to understand the general and different problems typical of power stations; 2) to discuss in technical and scientific meetings with appropriate terminology and scientific approach; 3) to identify approximate solutions for typical power stations issues; 4) to improve the ability to work in team with other students. Students are expected to spend 5/7 hours a week on average to review class materials and to work on projects.
Programma

Obiettivi formativi
The course aims to provide students with an in-depth understanding of the operational challenges posed by the decarbonization of the power sector, particularly in systems with high penetration of renewable energy sources. Through a hands-on, lab-based approach, students will learn how to independently develop and implement models for key ancillary services such as frequency regulation, energy arbitrage, power balancing, congestion management, and system restoration. Special attention is given to the technological solutions capable of providing these services, including battery storage systems, electric vehicles, inverter-based and synchronous generators, and demand response. By actively engaging in modeling activities, students will enhance their ability to apply theoretical knowledge to complex, real-world scenarios. They will also build critical judgement in assessing different flexibility solutions, while strengthening their ability to communicate technical results effectively. The course fosters independent learning and problem-solving skills, preparing students to adapt to the fast-evolving landscape of modern power systems and to continue their professional or academic development in highly interdisciplinary environments.
The student will be able to: develop models for analysing the operation of power resources on electricity markets, focusing on flexibility provision under different forms; design a techno-economic analysis for evaluating decarbonization initiatives, considering the role of multi-services provision and multi-energy districts; assess correctly the flexibility exploitable from different technologies and its provision to the power system.

Obiettivi formativi
The course focuses on the study of the evolution of electricity systems needed to enable a significant supply from renewable energy sources (RESs). In this perspective, we focus on the impact of RESs on the electricity system (market and networks). Market rules should ensure that conventional power stations are suitably operated even in the presence of large contributions from renewable generation; the different role that will be covered from RES generators that have some degree of programmability, as mini-hydro, biomasses and biogas, will also be highlighted. The impact on networks will be covered: transmission system will be mainly impacted by the massive contribution of wind energy; as for distribution networks (DNs), both MV and LV, it will be highlighted as the current structure does not allow the full integration of RESs generation into the system. The evolution of DNs will be addressed in the context of smart grid perspective to which distribution systems are gradually moving. For this topic, some details about technical solutions, about the use of ICT as enabling key will be given. Finally, some case studies and real life implementations will be described, with the relevant costs and benefits.
Lectures and exercise sessions will allow students to: Analyze and understand the problems deriving from the evolution of distribution grids towards a smart grid paradigm Identify and define the constraints, the interactions, and the different control techniques related to the introduction of distributed generation into an LV distribution network Identify and define the problems and the possible solutions related to the installation and usage of energy storage systems By successfully passing the final test the student is able to: Apply the acquired knowledge to real-life cases (possibly different from those analyzed during the lectures) Select and size an energy storage system according to the specific functions requested by DSO or end-user Define and write the specifications for the connection of renewable energy production plants with or without energy storage systems to LV and MV networks Autonomously judge and make decisions Communicate and explain in a clear way the selected solutions.

The goal of the course is to enable students to master the development of projects connected to satellite Earth Observations (EO), including technological frameworks and business processes that are necessary to deploy complex services or products based on data. The course covers the business and technological trends of EO, the business cases enacted by EO data and platforms, as well as EO data and platforms characteristics. The course enables students to acquire both theoretical and actionable knowledge of the Copernicus services and EO data and its relationship with the European Space Economy.
Dublin Descriptors Expected learning outcomes 1 Knowledge and understanding Students will learn how to:
Understand capabilities of satellite EO in project business development
Understand the phases of EO project business development and the specific activities associated with each phase 2 Applying knowledge and understanding Given specific project cases, students will be able to:
Apply the theory to assess the capabilities of EO to accomplish real business cases
Identify EO data and platforms suitable for specific business cases
Detail project business development requirements and documentation 3 Making judgements Given a relatively complex problem, students will be able to:
Analyse and understand the goals, assumptions and requirements associated with EO data and services and EO project business
Define the needed verification and validation activities
Estimate the resources needed for project development, identify risks, and define mitigation actions 4 Communication Students will learn how to:
Write documentation on project requirements and implementation
Present their work in front of colleagues, tutors, and companies 5 Lifelong learning skills Students will learn how to:

Develop a real project
Programma
The core theoretical and practical topics of this course module are:
Satellite Earth Observation principles
Earth Observation data handling technologies
Earth Observation data services and platforms
New Space Economy ecosystem and market overview
Satellite-based business application design and development
Satellite-based projects management tools and methods
Business development processes and methods Extensive practical activities will focus on the development of case studies, proposed and supervised by real companies and organisations active in Earth Observation data exploitation. There are three key elements in this course: Academics class: Lectures on relevant New Space Economy, Copernicus and Earth Observation topics. Interaction with industry and practitioners: Guests companies will be invited to expose students to real-life experiences. One or more real Earth Observation projects will be presented and discussed with specific questions/challenges proposed to the students and debriefed with the expert. Development of major coursework. Students will be required to develop major coursework concerning a real Earth Observation project planned or delivered in Italy or abroad. The students will critically evaluate this project, present their findings to hypothetical decision-makers, and will prepare a report. This will be group work and a certain number of lectures will be devoted to introducing the coursework, providing feedback during the development, and presenting the results.
