Desing of PKS type TRIPOD
Coufal, Jiří ; Knoflíček, Radek (referee) ; Holub, Michal (advisor)
The thesis acquaints the reader with issues of manipulators based on parallel kinematic structures. It includes also the description of the construction procedure of chosen mechanism. Introductory search part specifies selected terms relating to building elements and describes their requirements. Alternatives of construction and used types of manipulators are shown in the illustrative images with labels. Next chapters deal with projects of selected parallel mechanism and methodologies of constructions. These chapters describe the design of all devised construction nodes. The construction and testing of the produced prototype is properly documented, indicating the resulting knowledge.

Partial Discharge in High Frequency Electronic Equipment
Havlíček, Tomáš ; Maschke, Jan (referee) ; Dřímal,, Jiří (referee) ; Boušek, Jaroslav (advisor)
The presented thesis is focused on knowledge extension in the area of partial discharge measurements and evaluation at frequencies higher than 1 kHz. The thesis includes the design and set up of the measuring workplace equipped for measuring partial discharges, including the methodology of the measuring and calibration procedures necessary for the achievement of reproducible results. Another part of the thesis deals with the technology of acoustical and electromagnetic sensors convenient for the diagnostics and localization of partial discharges in devices, that work at voltages above 500 V. Electrical circuits that enable data evaluation by using the signal from a sensor working on amplitude analysis principle were developed. For PD detection a PC controlled measuring device working on amplitude analysis principle had to be designed and realized. The possibilities of the workplace have been demonstrated in the process of development of the insulating systems for pulse transformers. Thesis results can significantly contribute to a higher quality of newly designed electronic devices and systems working at voltages above 500 V.
