Planned learning activities and teaching methods

Students are taught the course through lectures (4 hours per week) by means of PowerPoint presentation slides. Guided individual and/or group project and laboratory assignments are assigned to develop practical engineering skills while integrating the course theory. Further literature search is encouraged by assigning students to identify a specific problem related to some possible open research issues, gather relevant scientific information about how others have addressed the problem and report this information in written and/or orally. Lecture notes and presentations are available through the web for students to use in combination with the textbooks.

Practical sessions are held in computer laboratories where Matlab environment is being used and programming exercises are given to gain practical skills and to implement the theoretical concepts taught.
