Subject aims expressed by acquired skills and competences

The aim of the course is to get acquainted with methods for testing machines, machine components and their diagnostics. Furthermore, hardware and software means for measuring quantities (sensors, measurement cards, signal analyzers, PULSE LabShop, MATLAB), input test signals and signal processing methodology in the range of knowledge necessary to master the preparation of a dissertation thesis. The student will be able to independently analyze the problem, define the methodology for testing and diagnosing machines and to present his results.
