Teaching methods
Lecture with a powerpoint presentation as the main support (available via iCampus). Even if the slides are used as a support for the lectures, an important part of the course is given orally and on the blackboard (e.g. explanations, examples, mathematic developments, etc.).
Quantitative exercises of dimensioning with a tutor.
Scientific articles are recommended for reading as a complement to the course.
Students may be instructed to visit a company of their choice and to study a unitary operation involved in the production process. A short, didactical and critical report is asked, in the form of a poster. The report is presented to other students.
Owing to the limited capacity of the class rooms, related to the restrictions of the COVID-19 crisis, some lecture may be given remotely (Teams).
