Learning activities and methodology
This course is composed of different activities: 1. Lectures. Main concepts (explanation and discussion). Different units in slides with the theoretical concepts. 2. Seminars. Various problems will be proposed for each unit. The solutions will be given after the seminars. 3. Lab sessions. Three practical cases will be proposed in each lab session. Before the lab session, a problem will be given to be solved before the lab session. A report about the work in the lab must be prepared after the session.
