17. Learning outcomes
A. Knowledge
  • Understands and applies the upload systems of railway diesel engines and the theoretical background of their operation.
  • Understands and can apply the mathematical procedures which are appropriate to solve the problems of the railway power transmission.
  • Understands and competently applies the methods which are appropriate to determine the characteristics of the energetic and environment-load of railway traction.
B. Skills
  • Able to apply the required mathematical and technological knowledge for solving the problems of the railway traction.
  • Able to identify, to evaluate and manage by system-approach the effect mechanism of the railway traction systems and processes.
  • Able to execute the condition surveys connected with diesel and electric traction, and based on this able to elaborate the complex developing proposals.
C. Attitudes
  • Open and receptive to know the development possibilities and knowledges which are taken place on the field of the railway traction.
  • Accepts the professional and ethical values-system connected with the professional area of the railway.
  • Pursuing to develop of new the methods and tools connected with the railway traction.
  • Pursuing to use complex and on system-oriented mentality based approach in the work.
D. Autonomy and Responsibility
  • Pro-activity in the solution of professional tasks, the self-standing application of the knowledges.
18. Requirements, way to determine a grade (obtain a signature)
During the semester there is necessary the individual solving of some tasks (ability, attitude, responsibility). The criterion of signature is both the active participation at the class (attitude), and the complete solving of the semester's tasks (knowledge, ability, autonomy). During the semester there is necessary to successfully write two midterm tests (knowledge, ability, autonomy). In the fields of attitudes and autonomy the results achieved in the semesters are included in the final classification by weight 50%. At the end of semester there is an examination (knowledge, ability, attitude).
19. Opportunity for repeat/retake and delayed completion
Possibility to refit the control works and the homeworks, to repeat the examination, properly to the Study and Exam Regulations.
