Teaching methods and learning activities

Theoretical-practical classes will be based on the presentation of case studies. Students will have to carry out small individual assignments.
Problems will also be discussed.
Use of computer applications to a computer-aided learning (mainly Matlab/Simulink, but other applications can also be used).

Software

The Mathworks - Matlab - Release 11.1

Evaluation Type

Distributed evaluation with final exam

Eligibility for exams

To be admitted to exams, students:
- have to attend classes (according to the rules);
- have to reach a minimum grade of 25% in each of the assignments;
- have to reach a minimum average grade of 40% in the assignments.

Calculation formula of final grade

1. Assignments – P1- average grade of the assignments
2. Exam – P2
Final grade will be graded from 0 to 20: FG= (0.3*P1 + 0.7*P2)/ 100*20 > = 9.5

And

Grade of the exam P2> 30%

Examinations or Special Assignments

Two individual assignments:
System dynamics
Processes control

Special assessment (TE, DA, ...)

It will take place an exam with a similar structure but with a different content from the final exam.

Classification improvement

It will take place an exam with a similar structure but with a different content from the final exam.

Observations

There is no course precedence. Solid know-how in mathematics, informatics, transport phenomena and reaction engineering is assumed
