Cost Benefit Analysis of Wind Power in Germany
Labunets, Nazariy ; Zajíček, Miroslav (advisor) ; Benčík, Daniel (referee)
The objective of this thesis is to perform a cost benefits analysis of the wind power sector in Germany, with the horizon of 2030. Various costs and benefits stemming from the expansion of wind power are inferred from literature review and studying the peculiarities of the German case. The magnitude of governmental support is calculated by applying the Weibull distribution of wind at different zones across Germany and power curves of 5 modern wind turbines, as specified by the law. A number of sensitivity analyses is performed on the main inputs for onshore installations. Under the baseline assumptions, the onshore sector is found as non-beneficial to the society, without a visible improving trend for the future. While the offshore sector does not reach a point where the benefits would start overweighing the cost until 2030, the overall trend look much more promising. Powered by TCPDF (www.tcpdf.org)

An evaluation of wind power plants effects on the environement using GIS
Komárková, Lenka ; Matějíček, Luboš (advisor) ; Přibil, Rudolf (referee)
Annotation: Wind turbines are devices that extract energy from renewable sources of energy and transform kinetic wind energy into electrical energy. Among renewable sources belong we rank sources which have the ability to partly of fully restore themselves, without human efforts. These include solar energy, geothermal energy, hydropower, tidal, wave and biomass energy. Most renewable energy has its origin in sunlight. The topic of the wind power, I chose because I find this topic up-to-date and controversial. At a time when in the whole world are non-renewable energy sources like coal, oil and natural gas is important to realize that other than by way of renewable energy sources will be avoided in future energy sources. Bachelor thesis will include a brief history of the use of wind, types of wind power, efficiency and new technologies such as offshore wind farms. The main focus will be to compare the pozitives and negatives of wind power plants and their impact on nature. Some problems associated with the operation of wind energy are exaggerated, some may be minimized. The aim will be to summarize the negatives and relevant sources to determine whether the excess of permitted limits and how wind affects the landscape and population. One part will be the noise map in the vicinity of the selected wind turbines.

"Everything's light and everything's upwards, the dance of elephants being uppermost". The metaphors of the movement in poetry of the poet Vladimir Holan.
Hudcová, Zuzana ; Heczková, Libuše (advisor) ; Wiendl, Jan (referee)
The purpose of the thesis is to deal with a writings of Vladimir Holan as a thematic unity, where the motifs are transformed. The metamorphosis depend on a time, when they have been written in. Our used method of his writings is in a chronological order. This thesis is focused on the motif of a movement and his metamorphosis in poetry of Vladimir Holan. The aim is to penetrate the problems of the movement as a physical activity and approached the movement as a confirmation of existence on a basis of Patočka's phenomenological phylosophy. Other chapters pay attention to analysis of motifs of movement, which are recognizable in Holan's poetry. Their feature change from lightness and freedom to heaviness and limitation. Afterwards the point of this work reaches the axis: a wind - a wave - a water flowed - a bird - a cloud - a stone - a snake - a wall. Due to the better understanding of Holan's work, we make a passing comment about the motifs which are connected with notised above. These connections will able to put our thoughts about Holan's conception in order.

Analysis of The Effects of Wind on The Steel Ventilated Facade
Kloss, Tomáš ; Žák,, Antonín (referee) ; Hron, Lukáš (advisor)
This master´s thesis analyzes an effect of wind load on the ventilated facade claddings. The analysis is performed on the various types of facades, from unventilated to ventilated facades with a different geometrical arrangement of facade shell. The theoretical part describes the basic knowledge about the theory of flow, turbulence modeling, determining an optimal domain, verification of the calculation model and user interface in the ANSYS software. The final part compares the value of the wind load reduction depending on the change of the gap widths and the size of ventilated spaces. The resulting values are obtained by CFD simulations. The thesis includes a design and an assessment of the steel hall construction.

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.

Search for harmony in artistic expression
BOUDOVÁ, Julie
The aim of this paper is cognition of eastern art feng-shui, selecting specific part and its subsequent putting into practise at Elementary Art School. It deals with "Theory of the five elements", which includes fire, earth, metal, water and wood. The theoretical part describes the theory of feng-shui and short history of eastern art, foundations of art education and different kinds of art creation, mainly spatial and action creation. The practise part is a note of teaching at Elementary Art School and presentation this topic into the school practise.

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.

Small Wind Power Plant Project
Görig, Tomáš ; Paar, Martin (referee) ; Matoušek, Antonín (advisor)
This thesis deals with finding an suitable locality for construction and technical design of small wind power plant station. The several ways are described and the best one is chosen. Also are projected and described several choices of usage the produced energy. Next part deals with economical side of power plant project as well as the ways of usage the produced energy. Results of this evaluation helped the investor to choose the best option.

Compare prices of electricity from nuclear power and renewable energy sources
Sláma, Miloslav ; Varmuža, Jan (referee) ; Radil, Lukáš (advisor)
This work deals with the components that that creates price of electricity and the regulation of electricity prices. It explains methods of regulation, setting electricity prices. It examines the factors that affect it. It also deals with the calculation of the price of electricity from various energy sources. It studies Support RES system, the conditions for obtaining and statistical data on development aid. It adds alternative sources of energy and their future and security.
