Rules for evaluation and completion of the course
Graded course-unit credit system. The student evaluation depends on the active attendance and the correctly solved separate numerical set of theoretical exerceces. The exam consists of the numerical part and the oral examination, studens have to show basic theoretical, numerical and practical knowledge in the branch. The use of defined literature materials in the numerical part of exem are allowed.
