Demonstration of the syllabus coherence with the UC intended learning outcomes

The classes are theoretical and practical.
After exposition, the contents of the lesson is illustrated through application examples and resolution of exercises.
In addition students carry out a work to familiarize themselves with the subjects taught, on the same topics discussed during classes.
