### Teaching method

Classes are theoretical, practical and laboratory. Concepts are introduced in theoretical classes, where simple examples of application are presented. In the practical classes, students apply the concepts to practical examples. In the laboratory classes, students perform laboratory tests in order to complement the theory and practical application with experimental teaching. Evaluation has theoretical, practical and experimental components.

### Evaluation method

Two tests or final exam, plus reports from laboratory classes.
