Proposal of new locality electrification
Foltýn, Petr ; Hájek, Ladislav (referee) ; Topolánek, David (advisor)
This master’s thesis is concerned with the proposal of new locality electrification. There are 59 detached houses. The thesis is divided into theoretical part and computational part. In the theoretical part, there are all documents necessary for the successful proposal of the electrification. In the computational part is drafted distribution substation, high voltage power cable, proposal of low voltage power cables and protection. Each part is made for two versions (for the degree of electrification A and for the degree of electrification C) and recorded in cadastral maps. The proposal of distribution substation and high voltage power cable is made by traditional method - all calculations are processed by the designer. Low-voltage power cables and protection are implemented in a computer program Sichr (version 11.01) OEZ company.

Antistatistic properties of materials in engineering practice
Vodička, Tomáš ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
The bachelor thesis deals with the properties of antistatic materials in engineering practice. The theoretical part described mathematically and physically electric field, the principle of electrification, triboelectric effect, types of electrostatic discharges, types of antitatic materials and methods of measurement surface and volume resistivity. In the practical part is designed the automated measuring workplace with electrometer Keithley 6517 and with the test chamber Keithley 8009, creating an application in Agilent VEE Pro, measurement of surface and volume resistivity on commercial materials and materials with various surface finishes, realized by cathode sputtering and the inclusion of materials in each group.

Hodnocení výstupních parametrů elektomobilů
Diviš, Ondřej
The diploma thesis is devoted to the evaluation of the output parameters of electric cars. In the first part, they are described in detail individual construction solutions of electric cars and hybrid vehicles. Another section deals with the main advantages and disadvantages of individual construction solutions. Furthermore, they are outlined here possible development directions in the field of electromobility. The practical part of the work deals with the measurement of acceleration depending on time and the course of the increase in speed during acceleration in electric cars and vehicles with an internal combustion engine with an automatic transmission. The results showed that electric cars have better acceleration characteristics than vehicles with combustion engines with automatic transmission. In the case of electric vehicles, a linear increase in speed occurs, whereas in the case of internal combustion engine vehicles, an uneven increase in vehicle speed over time can be observed further during the reassignment of individual gears. As part of the evaluation of driving modes, it was also found that all vehicles achieved the best acceleration characteristics in the "Sport" mode.

Selected issue of electric personal means of transport movement
Svoboda, Daniel ; Stáňa, Ivo (referee) ; Bradáč, Albert (advisor)
This thesis deals with the analysis of current electric conveyors, especially those with automatic levelling, their construction, and their differences from other electric conveyors. The thesis also includes the legal regulations for this issue in different countries. The measurements made consist of a comparison of different passenger carriers in various practical tests, which tell about the real use of these vehicles in real traffic.

The developement of urban build-up area and urban infrastructure in Benešov in the years 1918-1939
Roubík, Michal ; Jakubec, Ivan (advisor) ; Sejk, Michal (referee)
In my diploma thesis "The Development of Urban Build-up Area and Urban Infrastructure in Benešov in the Years 1918 - 1939", I explore one chapter in the development of a small agricultural town during the era of the First Czechoslovak Republic. This thesis is a contribution to the history of Czech towns during the interwar period and its topic corresponds to the research project of the Institute of Economic and Social History at the Faculty of Arts, Charles University in Prague, within the frame of which I worked on this thesis. The thesis was written mainly based on research of the resources in the State District Archives in Benešov (a branch office of the State Regional Archives in Prague) and of a wide range of relevant specialized literature. The introduction consists of a chapter offering a complex summary of the most important moments and changes in the development of Benešov during the examined period. Apart from the history of Benešov, it also shows the role of the town in the region and the relation of its development to other municipalities in the country. The focal point of the thesis lays in the extensive yet lucid chapters examining architectural development of the town (the essential moments, context, but also particular interesting buildings) and the development of its infrastructure...

Nikola Tesla - Genius, who changed the World
Fexová, Lucie ; Beneš, Zdeněk (advisor) ; Čechura, Jaroslav (referee)
Nikola Tesla - Genius who changed the world This bachelor thesis tells the story of life and work of Serbian inventor Nikola Tesla and it's mainly dedicated to years, which he spent in America. In the context of that time it highlights the importance of his inventions, some of which have significantly affected today's technology. The largest part of the work, occupy two Tesla's long life disputes which affected his career and personal life. The first one of these, "war of currents", was between Tesla and Edison. The second one between Tesla and Marconi passed because of invention of radio. The development of both disputes is described from the historical, economical and technological side, which focuses on the consequences for today's world. At the end of the text, there is a brief presentation of lesser-known Tesla's inventions and various recognitions which he received for his contribution to science.
