Teaching Methodologies and Assessment Criteria The syllabus of the course will be explained and discussed classes orally, with the use of slides. In order to consolidate the contents presented there will be problem solving and analysis of application examples tasks.

The theoretical lessons will be complemented with experimental practical work taking place in the laboratory to support the discipline. At the end of each lab work students will have to prepare a written report.

Final grade = Assessment of the theoretical component (weight of 80%) + Continuous assessment of laboratory component (weight of 20%, a minimum score of 10 of a total of 20 is mandatory).

The assessment of the theoretical component consists in the completion of an one term test (weight of 60%) + 3 written mini-tests (weight of 20%), during the teaching-learning period, or a final exam (80%). The student will be exempted from the final exam, if the final grade of teaching-learning period is greater than or equal to 10 of a total of 20.
Language Portuguese. Tutorial support is available in English.
