Teaching method

Theoretical exposition class with presentation of power point illustrations. Presentation of several case studies and practical application. Practical classes with the realization of problems in which the statement is previously provided. Clarification of the realization of problems. Carrying out some laboratory work

Evaluation method

 The evaluation will consist of 2 written tests, T1 and T2 complemented by an evaluation component (A) related to a monograph. The weight of the evaluation of T1 is 40%, T2 is 40% and A is 20%. The final grade is calculated N = 0.4T1 +0.4T2 + 0.2A. For exemption from assessment by written exam (E), the value of N must be equal to or greater than 9.5 out
of 20.
