Anotace:

The main aim of subject is scientific and technical information in the field

of diagnostic systems. The rapidly growing complexity of technical devices

has increased the need to knowledge of new efficient and concurrently

cost-effective test methods. The study course concentrates in areas of

non-destructive testing, vibration analysis of machines and testing of

digital circuits.
