Turbo-chargers
Klimtová, Daniela ; Vondrášek, Zbyněk (advisor) ; Ryzhenko, Volodymyr (referee)
This thesis is focused on supercharging reciprocating internal combustion engines. The introduction describes the history of turbocharging. The next section describes the basic concepts necessary to understand the issues and principles of mechanical supercharging blowers. The bulk of this work is devoted to using the turbo blowers, design and control type of turbochargers. The following describes the most common types of damages hot to prevent failures and how to take care the best of the turbocharger. Also the practical measurements for different types of cars with different turbochargers were made and than the subsequent evaluation of the measured values noted. The goal is to compare the various types of turbochargers, pointing out their strengths and weaknesses.

Lighting of interior spaces on buildings
Chouň, Václav ; Vondrášek, Zbyněk (advisor) ; Ryzhenko, Volodymyr (referee)
The bachelor thesis is focused on artificial lighting of interior spaces, evaluation and comparison of electric light sources and description methods of controlling appropriate of lighting. In the first chapter the author focuses on the description of electromagnetic radiation, artificial lighting with a description of the basic quantities of lighting technology that characterize artificial light and area of lighting. He also describes the construction and parameters of electric light sources and methods of controlling stratification of lighting. In the last part, the author presents a comparison of the parameters of the electric light sources and in conclusion he proposes an algorithm of choice the light sources, based on the parameters of the area.
