OVERVIEW

The teaching unit introduces students to the complex interactions that globally regulate the relationships between economic growth, mobility and sustainable development.

From a technological point of view, the problems related to the different uses of electrical systems in public and private mobility are summarized, highlighting in particular the aspects relating to performance, energy consumption, pollution.

Some peculiarities of the railway systems are treated and particular prominence is given to planning and economic problems in local public transport.

EXAM DESCRIPTION

Oral exam.

Use of MATLAB/Simulink software during the oral exam.

Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Federico Scarpa (federico.scarpa@unige.it ), the School's disability liaison.

ASSESSMENT METHODS

The exam aims to verify the student's ability to deal with complex problems as a synthesis of multidisciplinary skills acquired in analogy to what might be required in the workplace.
The ability to create a simulation model in MATLAB/Simulink environment will be evaluated using the software directly during the exam.
During the group laboratory exercises, the ability to manage social interactions with a collaborative attitude and the ability to develop critical reflection and strategic thinking will be evaluated.
