Teaching methods and learning activities
In theoretical classes the fundamental concepts are exposed .Illustrtive applications of these concepts are solved. In pratical classes, the students solve application exercises individually or in group.

Eligibility for exams
Three short tests, around 15 minutes each, will be given in three theoretical classes along the course. These tests will be announced in each previous theoretical class. The questions are of the type true or false. To have frequency, the students must have a minimum average mark of 6 in these mini-tests.
