The topic of the thesis is economical appraising of run the power from cogeneration units to different voltage level. There is sloves in the text, how and under what conditions we can find an optimal solution for the deployment of cogeneration units to the electricity network. The main criterion is the loss of networks and their economic evaluation. We are a description of the different types of cogeneration units, the economic balance and a treatise on losses in electrical networks.

Master’s thesis focuses on renewable and alternative energy sources and their operation in the Czech Republic. First part of this work deals with legislative support of the renewable energy sources and with other related documents. Next chapters describe each kind of renewable energy sources and their contemporary energy market share. In this work there are also economic analyses of electricity and eventually heat productions which are produced on concrete plants by sources using renewable energy. There is a comparison between regular and renewable energy sources in the next chapter. Final evaluation of different energy sources and their possibilities of using are described in the final part of the thesis.

The aim of this diploma thesis addresses issues related to obtaining methodology for the production manager´s decision-making process in the field of technology selection, suitable tooling and cutting tools selection for a specific order or particular production plan. Evaluation of the manufacturing process while taking into consideration complexion of process controlling and contexture to the economy of this process. Analysis and evaluation of technological and economical aspects of a manufacturing process of the CNC chip machining in a real environment is targeted on the field of tooling, its selection, purchase, economy and consumption. The process controlling of technology is based on this analysis as well as the formulation of measuring by economic indicators such as economy, productivity, profitability etc. The analysis of important factors and parameters of this process demonstrated an influence on economy of the company. Several model cases have been created from the company records and from the provided research, the output of which became a basic methodology. The output of the analysis indicates possible directions of a management decision making. Thanks to a complex technical-economic view this thesis can serve as a methodological instrument for decision makers in the field of technology and cutting tool selections as well as an economy of production process improvement.

The diploma thesis is focused on possibility of usage biologically decompostable wastes in the biogas plant. The first part of this thesis describes principal production of the manure gas and as well concrete biogas plants, where are shown different approaches and technologies. The main target of the thesis is based on biogas plant design for manipulation with biologically communal wastes from VUT v Brno and chosen parts of Brno. To the proper design of the biogas plant precede evaluation of accesible wastes from choosen localities. Since we consider wastes from households, the way of collection of those wastes is designed. The thesis also consider economic balance and assesment of the biogas plant. Investment costs are predicted, process costs are evaluated and as well profit from selling of the electric energy is consider, profits from charges for manipulation with wastes and profits from selling of compost.

This dissertation thesis is focused on explaining the broad issue of the non-conventional machining by an abrasive water jet. Introductory chapters deal with various techniques and methods of water-jet cutting and analyze them. Then the following text provides us with a detailed description of the machine itself so that people can understand the way how this technology works. The third chapter is focused on the quality of the resulting surface and the possibility of affecting it by technological parameters. This part is connected with the practical part of my thesis, in which the resultant surfaces of various materials made by different cutting parameters were compared. Subsequent section outlines the development of this technology. The last chapter contains technical and economic evaluation.

The master thesis is focused on the area of low-cost aviation in Europe. Discusses the economics of air carriers and analyzes statistical data on which compares the functioning of selected carriers. In submitted paper there are simultaneously analyzed the destinations network and selected European routes for particular air carriers. Analyses are supplemented by proposals for future possible ways to improve the functioning of the economy. In conclusion is proposed the new model of low-cost air carrier, which is based on a new system of pricing of tickets.

Doctoral thesis deals with domain of electric energy storage. It seeks to define the methods of accumulation, which can be used in industrial applications and define the conditions for the use of storage systems in electric power systems with extended penetration of renewable energy sources. In the context of current developments in this field is analyzed detail one of the perspective storage systems - Vanadium Redox Battery (VRB). One of the outcomes of this work is economic and energy analysis of storage systems, which are conceived with a disproportion between production and consumption of energy. The work was supported by the Centre for Research and Utilization of Renewable Energy (CVVOZE) no. CZ.1.05/2.1.00/01.0014 and research project no. FEKT S-11-9.

The thesis deals with the issue of enhancing the quality of providing services at a real hotel in Telč, the Vysočina Region. The hotel is in need of certain adjustments in purpose to improve current services. When processing this thesis I delt with factual economic, operating and technical figures connected to the latest economic activity of the hotel. In the proposal part I presents series of suggestions that could recondition provided services, and therefore, draw attention of more customers. It is indisputable that a considerable amount of money would be necessary to invest first. However, the returnability should bring overal effect in prosperity of the whole hotel.

The dissertation deals with heating of the administrative building. The building is heated with the floor heating and the panel heating units. The heating source is an air to water heat pump with a bivalent heating from the central heat supplying (CZT). I deal in the project with design, dimension and connection of all these parts.

This diploma thesis deals with the issue of enhancing quality of services provided in the Myslivna Hotel. It is necessary to increase the level of current services by a number of measures. When working on my thesis, I based on real economic, operational and technical data carried out within full operation of the Myslivna Hotel. In the innovation section I present measures that can lead to an increasing trend of occupancy and the quality ot the services provided there. There is a need to spend a considerable amount of money on the realization of all the proposals, but their return shoud definitely have a very positive effect on the function and prospertiy of the Myslivna Hotel.
