The goal of this master thesis is to analyse the potential of LNG for the Central European region with the emphasis on the strategic role of LNG imports in strengthening the energy security of the region and its possible role in replacing the traditional fuels in the transport sector of the Visegrad Group countries. The increasing availability of LNG, together with the predictions of its rapidly growing global supply in the following years, offers a window of opportunity for the Central European states. Particularly when it comes to their energy security, as the growing access to LNG supplies translates into a growing competition for the existing pipeline supplies from Russia. Furthermore, the thesis also focuses on the potential of LNG as an alternative fuel in the inland waterway and heavy duty road transportation of the Visegrad Group countries and the steps that these countries take to integrate LNG fuel in their transport sector.

The first chapter of the diploma thesis describes Energy policy of the European Union, especially its development, present state and its goals. This chapter also contains information about development of the single energy market. The second part of the thesis analyses oil and natural gas import dependence of the whole European Union and its Member States as well. It shows its rate and also the structure of suppliers, moreover, it describes total production, consumption and reserves of these fosil fuels. The third chapter outlines the ways how to reduce the import dependence. The last part familiarises readers with the main initiatives of the European Union in the field of environmental protection.

Today's world needs increasing amounts of energy for satisfaction of all human needs and wants. The fundamental problem is enormous disproportion among the areas with the largest energy consumption and places with the greatest energy reserves. This thesis set out to analyze the economic vulnerability of the biggest players in the world in terms of energy self-(in)sufficiency. The main focus of this thesis is to evaluate the status and future potential on the issue of fossil fuels, especially oil, natural gas and coal in the three world centers, the U.S., the EU and China. The thesis contains information about the alternative "clean" energy sources as well. Future energy development in these countries will affect their position in the world economy and mutual relations and also impact the current balance of power of these players.

The master thesis describes the methodology of laboratory and field measurements of tractors and tractor kits. It also contains graphical and tabular processing of measurement data and subsequent evaluation of the results obtained. It deals with the influence of power in the upper rod of three point hinge on wheel slip, work efficiency and fuel consumption.

The aim of this thesis was to create a model of thermal conversion of solid fuel. This is achieved by means of standard modelling tools included in software ANSYS Fluent in combination with user-defined functions (UDF). In first part of thesis basic approaches to CFD modelling of solid fuel combustion are presented. Building of a mathematical model and corresponding algorithms follows. Individual parts of a created model and its parts are tested on simple physical cases and then on case of experimental reactor for analysing biomass combustion.

This thesis focuses on a technology called cylinder deactivation. The technology helps reducing emissions and fuel consumption. The first part summarizes the possibilities of application of the cylinder deactivation technology as well as advantages resulting from combination with other technologies. The thesis also consists of two design options for valvetrain in inline four-cylinder engine and the results of simulations of dynamics of its cranktrain.

My thesis is engaged in business development of company Iveco Czech Republic, s.r.o. I would like to review current situation and then work up plan how to improve this situation.

This thesis deals with the use of the tractor in agricultural transport. The first part describes the current status in construction of tractor engines, transmissions and chassis that are used in tractors suitable for transport. The theoretical section includes an overview of the legislative requirements that must be followed for the tractor kits in transport on the road. The main objective of this thesis was to evaluate a measuring of fuel consumption and efficiency of the tractor JCB Fastrac 185-65 with two flatbed trailers. For this purpose was created the methodics off terrain measurement, which were carried out for different operation modes of the engine. The results were tabular and graphical processing including determining the accuracy of the method by calculating the relative error of measurement. For comparison a theoretical calculation of the consumed fuel was made. The aim of the measurements was to demonstrate fuel-saving during operation engine in the economic field and get an overview about fuel consumption and efficiency kits.

This thesis presents a comparison of fuel consumption and transportation efficiency of various transport vehicles in primary agricultural production. The first part deals with the possibility of transport of materials in agriculture. The following is a description of the compared vehicles. Finally, it describes the methodology of calculation of fuel consumption vehicles, which are then compared.

This thesis is focused on the analysis of current state of production technology and quality control of high-pressure reservoir. It deals mainly on the macro-metallographic test of the quality and position of the weld, the posibility of it´s implementation, organization of workplace. Task of this thesis is to find alternative methods of testing. Part of thesis is design and implementation of a new workplace´s layout based on experiment with using of alternative method of testing and assessment of implementation to achal process. The main objective is to improve the working condition and reduction of time for testing.
