Teaching method
Lectures delivered using Datashow with contents available in the syllabus internet page and pratical study sessions which include problem-solving as well as research and discussion on relevant topics.

Evaluation method
1. Frequence to the UC: presentation of an essay and presence in 2/3 of the lectures. Only the students that have frequency will be evaluated.
2. Grade of teory (75%):
(i) continuous evaluation by 2 written evaluations: the final teory grade will be the average of the 2 evaluations and has to be ≥ 9.5 values.
(ii) evaluation by final exam: the students that are not approved in the continuous evaluation can be evaluated in a final exam. The grade of the exame will the grade of the teory and has to be ≥ 9.5 values.
3. Grade of the seminar (25%). The grade of the seminar will have two components:
(i) Preparation of short description of the seminar with a maximum of 5000 caracters (including spaces) and an abstract with a maximum of 1000 caracters (including spaces) (15% of the final grade)
(ii) presentation of a poster (5% of the final grade)
(iii) Critical analysis of the poster/essay of another group (5% of the final grade)
4. The final grade will be given by: Final grade=75% teory grade + 25% seminar grade
To obtain approval to the UC the final grade has to be ≥ 9.5 values.
