Influence of chemical agents on stability of PTC ceramics based on BaTiO3
 Koller, Kryštof ; Švec, Jiří (referee) ; Sita, Zdeněk (advisor)
The thesis deals with the study of the influences of selected groups of chemical agents on the stability of PTC ceramics based on BaTiO3. The experimental part includes elaboration of methodology for determination of these influences, their evaluation, including the hypotheses for their description, and evaluation of groups of chemical agents having these influences.

Intrinsically safe line analyzer
 Wurzel, Tomáš ; Málek, Petr (referee) ; Beneš, Petr (advisor)
The main goal of this thesis is to design intrinsically safe line analyzer. Thesis describes a device that consists of three measuring circuits and a communication circuit. The device is required to measure posistor resistance, isolation state of power cable and line continuity in potentially explosive areas. Document describes basic requirements of ATEX directive matching standards that are related to device. The function of each logical part of the device is described with help of block diagram. After the basic function description an electrical schematic design and component selection is discussed. After this a printed circuit board design follows. Another part of the thesis describes testing software development. At the end of the document the device is assembler and its basic function is verified.
