Teaching method
Lectures and problem-solving sessions, supported by data show projection of figures/plots/text included either in the documentation supplied directly by the teacher or in the recommended bibliography.
Evaluation method
In order to get frequency the student have to attend all 5 laboratory sessions (with previous preparation) and to submit the proposed questionnaire at the end of each practical session.
The evaluation has 2 components: theoretical (T) and laboratorial (L). The final classification is calculated according: 0.25 x L + 0.75 x T.
To get approval in the theoretical part it is necessary to obtain positive (higher or equal to 10) classification. It can be done by 2 mid-term tests or by final exam.
The laboratorial classification results from a test at the end of the term or by final exam. It is necessary to obtain classification equal or higher than 10.
