17. Learning outcomes
A. Knowledge
  • Understands and applies the mathematical and scientific principles, relations and procedures necessary to cultivate professional area of the railway vehicle-dynamic.
  • Understands and can apply in a wide circle the theories and terminologies elaborated for professional area of railway vehicle-dynamics.
  • In details knows and understands the data collection methods and problem solving techniques of the railway vehicle-dynamics.
  • Knows and understands the methods of the computer modelling and simulation which are connected with the railway vehicle-dynamics.
  • Knows the problem solving techniques which are applicable in the research or scientific work.
B. Skills
  • Able to apply the required mathematical and scientific principles and procedures for solving the problems coming up in the railway vehicle-dynamics.
  • Able to apply in innovative way the principles and terminologies of the railway vehicle-dynamics.
  • Able to identify, to evaluate and manage by system-approach the effect mechanism of the dynamical processes coming up in the railway vehicles.
C. Attitudes
  • Open and receptive to know and to accept the developments and innovations which are taken place on the field of the speciality of railway vehicle dynamics.
  • Accepts the professional and ethical values-system connected with the professional area of the railway.
  • Pursuing to develop of the new methods and tools connected with the railway vehicles.
  • Pursuing to use complex and on system-oriented mentality based approach to the processes.
D. Autonomy and Responsibility
  • Pro-activity in the solution of professional tasks, the self-standing selection of the solution methods.
18. Requirements, way to determine a grade (obtain a signature)
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.
