N degrees of freedom systems 2CFU
Digital signal processing, basic principles 1CFU
Lessons and lab activities
Projects development during the teaching period. Groups of students will develop some projects. Each group will receive a problem to investigate. The problem is not a simple exercise. It is a way to learn the topic deeply and to prove that is has been well understood. The group will produce a Report and will present the work to the class (Powerpoint), 15minutes Rubrics. Clarity: Grammar correctness Sentences are clear, ideas are well explained Objectives are clearly identified Initial dataset is complete Conclusions are supported by data Theory: The explanation is correct No plagiarism (cut and paste) The theoretical part is strictly related to the problem Implementation: Is the code well structured and commented? Is the model validated? Is the numerical implementation described in the report? Graphical quality: Clarity and quality of drawings Quality of figures, e.g. 2D and 3D plots (captions, labels, legend) Speaker: Is the speaker able to create interest? Is the speaker able to answer questions (with the help of the group)? Beyond: Deepening of one or more aspects of the project E.g.: discover something new; enlighten limitations of the theory or the solution We appreciate imagination and creativity • Evaluation of the projects. Weight 50%. Marks will be published before the first exam after the teaching period. • Theoretical part (15-60 min). Weight 50%. Open-ended questions. 3. In the case of need, further oral question is possible
Understand the engineering principles in mechanical system to identify, formulate and solve problems of mechanical vibrations.
To be able to find the source of vibration problems in mechanical system through research that includes identification, formulation, analysis, data interpretation based on engineering principles.
