Front lessons, numerical exercise and applications to didactic and design problems.Attendance
Attendance is highly recommended in order to acquire regularly and continuously the concepts of the Course, the theoretical and numerical methods are applied to exercise didactic and project cases. Interaction in class promotes both attention and effective learning.Type of evaluation
It is possible to undergo to a test 'in itinere' about at half of the Course. If the test is passed, then a final exam on the remaining part of the Course will have to be sustained.
