Thermoacoustic measurement of ultrasonic power
Vysoudil, Ladislav ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
The assignment of this work is to suggest structural design of thermoacoustic sensor and experimentally verify his function for testing intensity of ultrasound diagnostic systems. Then the measured results are compared with measurement by the hydrophone in ultrasonic measuring tank. Opening part of this work is focused on functional description of sensors and their construction, including functional description and construction of hydrophone. The rest of the work deals with project of thermoacoustic sensor and measuring with sensor and hydrophone and evaluation results of measurement. Intention of this work is to verify the correct function of designed thermoacoustic sensor with the help of comparison measurement with hydrophone.

Chimney load bearing structure
Hasala, Ivo ; Girgle,, František (referee) ; Šimůnek, Petr (advisor)
My chachelor work solves the static diagram shaft of the contemporary stach, a load, an analyse of inside powers in the programme SCIA ENGINEER and a review combination load M + N. The contemporary steel reinforcements is an appreciating to definite the combination load in six horizontal cuts along the height stach. My calculation includes the produce algorithm in the programme MS EXCEL for the appreciating choice intercircular cats of stach on the combination load M + N.

Modernization the Dukovany Nuclear Power Station
Kissler, Martin ; Martinec, Jiří (referee) ; Fiedler, Jan (advisor)
Thesis focuses on a detailed technical description of all important parts of secondary circuit in Dukovany power plant and its connection to other systems of power plant. In thesis are analyzed significant adjustments which have been made during the entire operation of power plant including in particular the actions associated with project called Utilization of project reserves of units EDU. In the main part of the thesis were carried out calculations of the power plant's power for states before and after the modernization and there is also analyzed the impact of individual changes on the whole power plant. These changes are with the entire secondary circuit drawn in the T-s diagram.

Magnetostriction vibration power generator
Šumpelová, Jana ; Singule, Vladislav (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with the idea of energy harvesting from mechanical vibration. It describes the magnetostrictive principle as a possibility to obtain an electrical energy. It is about a generator made of a beam with Terfenol-D material and a coil. The model of this device is created in Matlab/Simulink and FEMM application. For various values of measured vibration, these methods are then compared. In FEMM, you can improve energy gain by modeling of various environmental conditions and with using of another materials (e.g. by adding of permanent magnets). The outcome of the this thesis expresses the ability to harvest the energy with designed magnetostrictive generator compared to the already created models of the piezoelectric and electromagnetic generator. Based on these results, it is possible to determine which generator is more suitable for particular application.
