Modalità Erogazione

The agenda of the course is structured as follows: - four hours/week of frontal teaching on topics related to Teaching Units I, II, and III - two hours/week of supervised laboratory activity on topics pertaining to TU IV Weekly homework assignments are foreseen on topics related to topics covered in the lectures of the week. Students are asked to form teams of 4/5 elements and submit a design proposal to the teachers approval. The teams must deliver the final design work according to the time schedule agreed with the teacher. During the second part of the course, additional laboratory activities are foreseen to support the students teams in the development of the design work. The students are introduced to the use of the tools of analysis, simulation and optimisation, as well as to the basic programming skills required to setup the multidisciplinary design framework.

Modalità Frequenza

Although not mandatory, attendance is strongly recommended in consideration of the design-oriented nature of the course.

Modalità Valutazione

Each student is evaluated on the basis of three elements of judgement: - quality of the project (global rank for the entire team) - quality of the individual contribution to the project - level of preparation on the topics of TU I, II, III. The evaluation takes place through a project presentation and a viva voce exam.
