Measurement of meteorological variables
Škorpík, Daniel ; Harabiš, Vratislav (referee) ; Chmelař, Milan (advisor)
This bachelor thesis discusses about the basic meteorological variables, especially temperature and airflow. These magnitudes are measured using an anemometer which uses resistive sensors, namely, two thermistors of NTC type that described technology, operations, methods of scanning, sensor placement and implementation of such a device. After that was designed block diagram and circuit diagram. The meter is realized, than we describe the individual components and then is calibrated and tested. In conclusion, it is evaluated for use in medicine.

Using of Renewable Energy Sources for Family House Supply
Varmuža, Jan ; Macháček, Jan (referee) ; Toman, Petr (advisor)
This work is concerned to analysis and evaluation of present recoverable energy resources and position EU to them. In study is provided comparison of recoverable resources (biomass, water, wind, environment energy, and sun). The details are noted for all single cases. As the next addition are included various techniques „how to obtain and convert them“. In study are also noted which necessary equipments must be used and their proper location. In practical part is done comparison of barrier-layer photocell from polycrystalline and monocrystalline silicon and water insulating foil „EVALON SOLAR“. For comparison was taken only produced energy. Next step was financial analysis of each single system and comparison with pay-off in case that invested sum (actual price) was placed to bank under time deposit and share capital fund. During analysis of financial evaluation was found, that more suitable is system from polycrystalline silicon. Because of investors main condition is financial aspect, so for realization will be recommended system from polycrystalline silicon.

Mechanical Design of 110 kV Overhead Line
Guliš, Tomáš ; Sýkora, Martin (referee) ; Orságová, Jaroslava (advisor)
When designing overhead lines we must respect many influences that act on it. These are electrical effects and mechanical effects, caused in normal conditions by wind, frost and temperature. This bachelor’s thesis is mainly focused on comparison of calculation of separate load cases and comparison of parameters obtained by mechanical calculation of particular overhead line according to standards ČSN 33 3300 and ČSN EN 50341-1.

Atmospheric Phenomena
Radouš, Jakub ; Milet, Tomáš (referee) ; Kobrtek, Jozef (advisor)
This bachelor's thesis deals with a visualisation issue of several atmospheric phenomena by means of the OpenGL library. The work contains theoretical bases for rain, snowfall, lightning, fog, wind, tornado and rainbow, which are further converted to the form of algorithms. The outcome is an application with graphical user interface that is able to display seven natural phenomena set in a landscape.

Wind Energy Use on Flat Roofs of Buildings
Tůmová, Eliška ; Kabrhel,, Michal (referee) ; Horák, Petr (referee) ; Hirš, Jiří (advisor)
The PhD thesis is focused on determination of the method by which it is possible to specify the wind energy use potential on building flat roofs. In response to the need to reduce the production of CO2 emissions and increase energy self-sufficiency, it is necessary to use alternative energy supply systems and renewable resources as much as possible. Long-term and short-term wind parameters were measured to verify the of the resulting simulation velocity flow images. Based on the defined input parameters and the completed simulation, the resulting value of the potential is determined, namely the possible production of electricity for selected small wind power plants on the roof of the selected building during one year. In the thesis the individual steps of the method are stated and the verification of the established method is determined.

Renewable energy sources in CR
Sedlák, Pavel ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
The content of bachelor study is the technical recherche of the renewable resources of energy in the Czech Republic. I'm ineterested in a kind of renewable resources of energy. This especially contains wind energy, hydroenergy, solar energy and biomass. In each chapter you can find some informations about development, principle of function, technical characteristics, environmental impact and potential in the Czech Republic. At the end of this study are noted economy and legislation especially supports and prices of each renewable resource of energy.

Renewable Energy Source
Mašek, Martin ; Škvařil, Jan (referee) ; Fiedler, Jan (advisor)
My bachelor’s thesis deals with description and use of renewable energy resources in the Czech Republic. At the beginning of my thesis I characterize individual renewable energy resources and its today’s use. In the main part of the thesis I focus on wind energy in more details, especially technical description of the wind power plant. In the end of my thesis there is a description of the small workable wind power plant and its economic analysis.
