Teaching method

Lectures will cover the fundamental topics of the subject matter, which the students should complement with the given bibliography. All lecture materials will be supplied for further study. Lectures will include some time for questions and discussion of the subject matter.

Tutorial classes will be dedicated to exercises and guidance in the practical assignments, focusing on selected topics.

Class schedules and materials will be supplied online, as well as additional information regarding the course.

Evaluation method

The evaluation of this curricular unit is made by two components: theoretical/problems (T) and project (P). Each component contributes with 50% to the final grade.

Both components are evaluated in an integer scale from 0 to 20.

To pass, the student must have:

(i)  a grade of at least 9,5 points in the theoretical/problems component; and

(ii) a grade of at least 9.5 points in the project component;

The final grade is the weighted average of the two evaluation components (0.5×T + 0.5×P) on an integer scale from 0 to 20 points. If the final grade is higher than 17 points, there will be an oral test to defend the grade obtained. After the oral examination, the grade will not be less than 17 points. If a student with a computed final grade larger than 17 does not attend the oral examination, the final grade is automatically defined as 17 points.

Theoretical/problems component

Two written tests evaluate this component. The grade of this component is the average of the two written tests.

Alternatively, this component can be evaluated by a written exam. The exam will be graded in two independent parts, each corresponding to one test and replacing its grade if better.

 An extra point will be awarded in the theoretical-practical component that will evaluate the delivery of a report transcribing and deepening the contents of one theoretical class.

Project component

Two mini-projects evaluate this component.

Some tutorial classes will be allocated to the mini-projects.

The mini-projects are done in groups of students, but this component is evaluated individually.

The grading of the different evaluation components is rounded to the first decimal place. The final grade is rounded to the closest integer value.
