No weekly homework during weeks of the class, but a semester task counts 50% of the total that requires students to write report base on technology introduced in examples of each chapter and give a lecture of reports. Students in this course shall finish with their professional knowledge and ability and collect from literature / documents. At the end of the semester will be a final examination, which counts for another 50% of the total. The full score of this course is 100.
