Subject aims expressed by acquired skills and competences
The aim of the course is to become familiar with the methods of product testing and diagnostics to extent the necessary knowledge for the preparation of doctoral thesis, and mastery of the scientific methods of data processing. Student's partial knowledge is organized in the framework of doctoral studies so as to be capable of independent analysis, synthesis and presentation of their ideas.
