Airborne wind energy system
Killioglu, Can ; Popela, Robert (referee) ; Zikmund, Pavel (advisor)
The master's thesis deals with the issue of flying wind turbines, which is an innovative area of renewable energy. The main advantage of these power plants over conventional wind turbines is their ability to reach higher altitudes and thus take advantage of stronger wind conditions. An important part of the thesis is the aerodynamic analysis of the rotor in autorotation mode, which investigates the behaviour of the propeller rotor. Furthermore, the conceptual and structural design of a selected type of flying wind turbine is carried out.

History and development of czech power plant
PAVLOVSKÁ, Amalie
The main aim of the work was to understand the complex and demanding path in the development of energy and power engineering in the Czech lands from the end of the 19th century to the present. The introduction generally outlines the intention to briefly exclude the key moments that affected our energy. The next sections first describe the historical individual periods in which the power plants were built on the basis of certain conditions. Then I deal in detail with the most frequently used types of power plants in the Czech Republic with more emphasis on one of the modern technologies of the Temelín Nuclear Power Plant. The last larger chapter is a reflection on the possible development of energy in the future.

Freestyle kiteboarding methodology
Soukupová, Tereza ; Bačáková, Radka (advisor) ; Brtník, Tomáš (referee)
Title: Freestyle kiteboarding methodology Aims: The aim of the bachelor's thesis is to compile а methodological approach throughout the training of kiteboarding tricks. Methods: The thesis was written on the basis of the analysis of the documents, it is а expert work. The method of content analysis was used for the data processing from the Internet and books which were used as the main sources of the information and subsequent description of individual tricks. More information were gained by the informal way - interviewing the professional riders. Conclusion: А review of teaching kiteboarding tricks in the basic developement is worked out in the conclusion. Key Words: kite, board, wind, hooked tricks, air style, freeride

Measurement of changes in the inclination of the Velký Kosíř lookout tower structure due to the influence of wind stress
Smetana, Jonáš ; Bárta, Ladislav (referee) ; Bureš, Jiří (advisor)
This thesis deals with the issue of displacements and deformations of building constructions. Specifically, it deals with changes in the inclination of the Velký Kosíř lookout tower structure due to wind stresses. The first part of the thesis deals with the theoretical description of the issue of displacements and deformations of buildings and measurement methods. The second part presents the testing of the geodetic method used for dynamic measurement. This involves setting up a total station in an automatic tracking mode and aiming a reflecting prism. The third part then deals with the actual measurement of the lookout tower Velký Kosíř, evaluation of the stage measurement, interpretation of the results and comparison of the methods used. These methods are represented by the polar method in a standard mode and the polar method in the mode of automatic tracking of the reflection prism and measurements of dynamic acceleration using accelerometer. The final objective is an evaluation of the inclinations under given wind conditions and the evaluation of the lookout tower inclination in the long term.

Use of meteorology and historical comparisons atmospheric conditions for yachting and water sports
Hájek, Petr ; Jindra, Matouš (advisor) ; Dvorský, Jaroslav (referee)
Title: Use of meteorology and historicalcomparisons atmospheric conditions for yachting and water. Objectives: At work I use two basic methods of research. The method of content analysis and interview. Content analysis, I get the information for the theoretical part of the work, using professional sailing and meteorological publications. Furthermore, the method of non-standardized interview, which I took while visiting Mathematics - Physics Faculty at Charles University, Department of Meteorology and Climatology. Here I have discussed his work with Dr.. Joseph Brechler, PhD. Furthermore, with top windsurfing in the Black foothills and Nechranické dam. Methods: At work I used as a basic research methods method of content analysis and interview. Content analysis, I gained information for the theoretical part, the professional sailing and meteorological publications that deal with the issue. Non-standardized interview method I used when visiting Mathematics - Physics Faculty at Charles University, Department of Meteorology and Climatology. Here I discuss my work with Dr.. Joseph Brechler, PhD., Then Ing. Ružbatský in the foothills of the Black and F.Kasík of Nechranice. For wider acquaintance with the issues I was trying to get other sources of information on various internet portals related to...

Variations of solar wind parameters through solar cycle
Turčičová, Marie ; Šafránková, Jana (advisor) ; Ďurovcová, Tereza (referee)
Statistical analysis of data from satellites that operate in the vicinity of the Sun can partly contribute to the elucidation of complex processes around the Sun. This thesis is devoted to a long-term statistical study of particular parameters of the solar wind. We have used data from the Wind satellite, especially its measurements of the velocity, density and temperature of protons and α- particles. By using standard statistical tools, we explored their behaviour during the 23th and 24th solar cycles, including a comparison of both cycles. Our results are in accordance with other known studies.

Measurement System For Determining Forces Acting On Loose Concrete Roof Paver
Mancl, Vlastimil
This paper introduces the topic of measuring the wind-induced forces on a concrete roof pavers. It describes the creation of a system, allowing such measurements and it also proposes two methods. First discussed method is measuring differential pressure. The second is measuring the weight of a roof paver. This article proved, that those methods can give meaningful results and that the future research should continue to use and improve this measurement system.
