Learning objectives of the subject

The sessions are divided into theory and problems sessions and into laboratory practices. Theory and problem sessions

integrate the presentation of the basic theoretical concepts of thematic content of the course, applied examples are

described as exercises, and the teacher presents exercises for applying the concepts studied in theory classes and

proposes others for resolution by the student, individually or in groups.

In the laboratory practical sessions, experimental tests are developed and is the student, individually or in groups, who

must work aspects ruled by the teacher.
