Teaching Methods
The curricular unit is divided in theoretical classes for laying down the fundamental concepts and theoretical-practical classes for problem solving. Students will be required to hand-in a report for a practical assignment with either laboratory work or assessing the wind energy resource at a given location (real data on wind velocity and direction is provided).
Assessment
Assessment can be either through tests during the semester or final exam. In the case of an assessment throughout the semester, the following formula will be used for calculating the final mark:
Final mark: NF = 0.3*(NF1+NF2)+0.4*NT
Where: NF1: First Test NF2: Second Test NT: Thematic work with report
Any of these assessment components has a minimum mark of 8.0.
In the case of assessment by exam, the final mark will be the highest mark obtained:
Final mark: NF = Max(EN,ER)
Where: E1: Exam in first call E2: Exam in second call
Final mark: NF = 0.3*(NF1+NF2)+0.4*NT
Where: NF1: First Test NF2: Second Test NT: Thematic work with report
Any of these assessment components has a minimum mark of 8.0.
In the case of assessment by exam, the final mark will be the highest mark obtained:
Final mark: NF = Max(EN,ER)
Where: E1: Exam in first call E2: Exam in second call
