Pdf of the complete set of slides used during the course.
Teaching methods
Each lesson (in Italian) covers both theoretical and practical aspects. At least, one numerical example is shown for each topic.
Lessons are made by using slides (powerpoint).
Assessment methods
The exam is composed by two tests:
1) one written test (a numerical solution of a design problem)
2) one oral test
Teaching tools
Lessons are made by using slides (powerpoint).
A pdf copy of the slides (in Italian) is available for UNIBO students at virtuale.unibo.it.
