Teaching Methods
The theoretical contents of the curricular unit will be presented through lectures illustrated whenever possible with practical cases. Students are encouraged to apply the competences acquired through practical activities, including the analysis of case studies and exercises.
Learning Outcomes
This course involves the contact with mathematical and classical and advanced numerical methods. The principal aim is to provide skills for the exercise of theoretical and computational research.
