Turbocharger Performance Measurement
Ušiak, Michal ; Janoušek, Michal (referee) ; Vondrák, Adam (advisor)
The bachelor’s thesis deals with recent methods of measuring turbocharger characteristics. Besides an introduction to fundamental performance characteristics, such as compressor map and turbine map, thesis contains description of experimental methods of collecting such data, which is essential for designing a turbocharged power unit. Description of main parts of the test stands and limitations consequent upon the measuring methods is supposed to offer basic knowledge of turbocharger design validation to the reader. As an extension overview of tests increasing accuracy of these characteristics and a few additional and safety tests is presented. Examples of use of these characteristics in engineering calculations should give an image of significance of creating computational model from experimental collected data, which describes thermodynamics of the turbocharger.

Impact of energy consumption on economic growth and potential of renewable fuels
Torkhani, Marouan ; Janda, Karel (advisor) ; Havránek, Tomáš (referee)
This master thesis aims to examine the relationship between energy consumption and economic growth and between energy consumption and greenhouse emissions for the EU countries, using a panel time series data from 1996 to 2012 within a multivariate framework for 26 EU countries. The energies are composed from oil consumption, natural gas consumptions, and renewable energies including the biomass as a distinct part. To do that, Unit Root Tests, cointegration test, Pairwise Granger causality tests, and Error Correction Model are employed to find out the type of the causal relationship. The main results to denote are that, there is in the short run, a positive unidirectional causal relationship running from oil consumption to economic growth. We can as well denote a positive bidirectional causal relationship between renewable energies and economic growth and between greenhouse emissions and economic growth. However, there is an unexpected negative bidirectional causal relationship between biomass consumption and gas consumption. From the greenhouse emissions perspective, we can see in the short run, a negative bidirectional causal relationship between greenhouse emissions and renewable energies, and a positive unidirectional causal relationship running from both oil consumption and biomass consumption...

World oil market
Batryn, Maria ; Hinčica, Vít (advisor) ; Němečková, Iveta (referee)
In my bachelor thesis I deal with the situation on the world oil market. The aim is to get closer to the historical and current data of world oil consumption, its supplies and prices, and to outline the future state of the market and also to study alternative energy sources that could replace the currently widely used fossil fuel. To analyse world oil market I have used statistical reports, which are issued annually by the world important world organizations such as OPEC or IEA. Carried out research work is in progress to assess the current supply and demand for oil and at the same time it is estimated the possible scenario in the future oil trading. Biofuels and hydrogen are highlighted among the renewable sources which surely will play a major role in the coming years in search of other alternatives to oil and in which conceals a lot of potential. The view of this work is the outlook of the other years in terms of oil consumption and price trends and approaches the issue of alternative energy sources. Although they promise a bright future for these resources in the form of a reduction of our dependence on oil, research in this field has still many unresolved issues.

Influence of oil crisis on energy policy USA
Krydl, Ondřej ; Tajovský, Ladislav (advisor) ; Jeřábková, Zdenka (referee)
In 1973 the first oil crisis took place, which negatively affected all economies that are dependent on imported oil. In my thesis I deal with the impact of oil crisis on the development of energy policy in the United States. U.S. lawmakers adopted a series of measures and laws that were aimed at achieving energy independence the U.S. on imported fossil fuels. These laws place emphasis on the growth of domestic production and implementation of cost-effective energy saving technologies. The thesis explains the main reason for non-fulfillment of targets of energy programs, analyzes the factors which influenced the development of the oil market, and provides a comparison between the actual development of the energy with the development planned.
