The storage water plants problem appreciation
Archalous, Jakub ; Himr, Daniel (referee) ; Sloupenský, Zdeněk (advisor)
This bachelor’s thesis deals with the use of hydropower. It gives an overview of hydroelectric plants and describes mechanisms that convert water energy into electric energy. The most attention is paid to the principle and operation of pumped storage power plants and the machinery used there. Also the efficiency of the pumping cycle at Dlouhe Strane power plant is calculated.

Evaluation of operation of small hydropower plant
Bartoš, Josef ; Dráb, Aleš (referee) ; Špano, Miroslav (advisor)
The bachelor's thesis deals with the quantitative expression of the reliability of operation at MVE. In the introduction, the work deals with the theoretical part, especially a more detailed description of individual indicators and mathematical expression of these indicators. The following is a description of the power plant, which is divided into individual parts. Furthermore, the evaluation is presented, which is based mainly on the theoretical part and the results are displayed, among other things, in graphical form.

Reneweblw energy source at Slovakia
Szegedi, Peter ; Borbély, Richard (referee) ; Fiedler, Jan (advisor)
The bachelor thesis is divided into five main issues. The first issue is dealing with history of exploitation of water as a power supply in Slovakia and is describing current situation of exploitation of watercourses. The next part of the thesis is describing a present condition of power industry in Slovakia, its future perspective and a possibility of deriving benefit from the most perspective renewable resources of energy. The essential issue handles with water power stations ant its description. The last capture is focused on small hydroelectric power stations and technic – economical evaluation of three concrete SHPS. The conclusion is attending to short overview of information obtained by writing the bachelor thesis and to author’s own estimation of development of renewable energy sources situation in Slovakia.

Modeling thermal circuits using object methods
Holcman, Tomáš ; Mastný, Petr (referee) ; Baxant, Petr (advisor)
The aim of the bachelor’s thesis is creating programmer’s library in some object oriented programming language which should help calculating of thermodynamic schemas. The first part of the bachelor’s thesis is a short summary of the options of computing simplification of thermodynamic schemas using computer technology. The second part is focused on finding proper mathematical models of particular components of schemas. The next part brings forward a design of the system, separation of the library to particular sections, the design of helper classes and classes of each component. The fourth part considers choosing suitable programming language. Next step is the implementation of library, the solution of the problems linked with implementation in PHP version 5.2.x. Finally, some cases of using this library are presented, and future prospective progress of the library and linked software is adumbrated.

Design of turbocharger
Streďanská, Alexandra ; Šnajdárek, Ladislav (referee) ; Škorpík, Jiří (advisor)
Diploma thesis focus on the design of turbocharger in SW MS Excel. For required flow and pressure ratio, the thermodynamics parameters were calculated for the turbocharger. From these, geometry was designed and the condition of mediums was calculated for each part of the turbine and compressor. At last basic characteristics of the turbine and compressor on varying the regime of engine operation the rotation was made and offered an idea about the working point position.
