Syllabus
Course Objectives
The course also intends to provide the fundamental concepts for estimating the wave energy potential in a fixed location and to outline an overview of the devices for exploiting wave energy. Specifically, it addresses the study of oscillating systems for the conversion of wave energy: Oscillating Water Column (OWC) systems and floating bodies for the exploitation of wave energy
The objective of the course is to enable the student to acquire: i) the ability to re-elaborate what has been studied and to apply the acquired knowledge in practice: this also, and above all, in fields other than those in which the knowledge learned is traditionally used ( Knowledge, Understanding, Applied Knowledge); ii) the notions necessary to be able to independently deepen what has been learned, both independently and with originality, and through comparison with the teachers and with the other students, in order to use the basic knowledge as a starting "platform" that allows him to reach to further results characterized by an increasingly greater maturity and an increasingly broad autonomy of judgment (Autonomy of Judgment and Ability to Learn); iii) the ability to convey to one's interlocutors, in a clear and complete way, the knowledge acquired at the end of the training course developed within the course (Communication).
Course Prerequisites
Mathematical analysis, Physics
Teaching Methods
- Disciplinary classrooms
- Problem solving
- Project Based Learning
- The scientific method for STEM
Assessment Methods
The exam consists of an oral examination. During the interview, a case study identified by the student will be discussed.
During the oral discussion, the critical skills and methodological rigor achieved by the student will be evaluated, as well as the contributions of originality, with reference to the topics covered by the
course.
The oral examination aims to verify the level of knowledge and understanding of the course contents and to evaluate independent judgement, learning ability and communication ability. The discussion of the
case study chosen by the student has the aim of understanding the student's ability to re-elaborate what has been studied during the course and to apply the knowledge acquired in practice, in cases of interest different from those developed during the lessons.
The final grade will be awarded according to the following evaluation criteria:
30 cum laude: complete, in-depth and critical knowledge of the topics, excellent language skills, original interpretative ability, full ability to independently apply knowledge to solve the proposed
problems, with reference to case studies already covered during the course or new;
28 - 30: complete and in-depth knowledge of the topics, excellent language properties, complete and effective interpretative skills, able to independently apply the knowledge to solve the proposed
problems, with reference to case studies already covered during the course or new;
24 - 27: knowledge of the topics with a good degree of command, good language skills, correct and safe interpretative skills, good ability to correctly apply most of the knowledge to solve the proposed problems, with reference to the case studies already treated during the course or on the general analysis of new case studies;
20 - 23: adequate knowledge of the topics but limited mastery of the same, satisfactory language properties, correct interpretative ability, more than sufficient ability to independently apply the knowledge to solve the proposed problems, with reference to the case studies already covered during the course;
18 - 19: basic knowledge of the main topics, basic knowledge of technical language, sufficient interpretative ability, sufficient ability to apply the basic knowledge acquired; Insufficient: does not have an
acceptable knowledge of the topics covered during the course.
