Acquired competences:
Knowledge:

Understand, characterise and model the structure and function of the components and elements of mechanical systems, the design and interrelationship of the systems used. Knowledge of the terminology, key concepts and theories related to his/her field of specialisation.

Skills:

- On the basis of the acquired knowledge, students are able to design and operate refrigeration machines, design and operate internal combustion engines and pumps independently and in teams. - They are able to diagnose mechanical failures, select remedial actions and solve repair tasks. - Ability to apply the most important terminology, theories and procedures of the given technical discipline in the performance of related tasks. - Ability to understand and use the literature, computer and library resources specific to his/her field. - be open to learning about, adopting and authentically communicating professional and technological developments and innovations in the field of engineering.

Attitude:

Using his/her acquired technical knowledge, he/she strives to understand the observable phenomena as thoroughly as possible, to describe and explain their laws.

Autonomy and responsibilities:

It identifies the shortcomings of the technologies used, the risks of the processes and initiates measures to reduce them.

Additional professional competences:

Requirements, evaluation, grading:
Mid-term study requirements:
1 50-point paper from the theoretical material. 1 40-minute 20-point test in a computer lab.
Exam requirements:

To pass the examination, you must have passed the mid-term tests with a minimum of satisfactory marks. In addition, active participation in lectures and laboratories. The mid-semester control assignment can be replaced by a homework assignment, which must be discussed in advance with the lecturer of the subject. With an accepted homework assignment, the exam mark can be improved by one mark if the exam is passed and the grade is at least satisfactory. The examination is a written examination, one 100-point test. The mark will be determined in accordance with the examination regulations. The written result may be improved by one mark by oral examination.

Study aids, laboratory background:

Software lab and co-located support materials.
