Accumulation of energy in compressed air
Rešiliáno, Tomáš ; Kracík, Petr (referee) ; Pospíšil, Jiří (advisor)
The thesis deals with the principle and issues associated with operation of the storage power stations, known under the acronym CAES (Compressed Air Energy Storage). Examples of existing and upcoming CAES power stations from commercial sphere are listed and described there. The paper also includes an overview of basic CAES station wiring diagrams and a simplified calculation is performed to compare the efficiency of the chosen diagrams. In the final part of the thesis there is a scheme of so-called adiabatic CAES designed and calculated. For this type of device has been designed suitable wiring and a thermodynamic calculation of the cycle was performed for the purpose of evaluation.

Lifetime and reliability of thermoelectric modules
Rešiliáno, Tomáš ; Šnajdárek, Ladislav (referee) ; Brázdil, Marian (advisor)
The thesis describes the construction of thermoelectric modules used for both electricity production and cooling. Above all, the thesis describes the influences, along with their causes and consequences, that have a major impact on reliability and long-term operation of thermoelectric modules. The thesis further describes the basic quantities with which we can assess the thermoelectric modules and also describes basic methods to measure these quantities. For the purposes of the thesis was conducted an experiment, during which the internal electrical resistance of unused, used and damaged thermoelectric modules was measured. The results were compared with the physical condition and operational history of the measured thermoelectric modules.
