This dissertation thesis deals with the diagnotics of power oil transformer. It consists of the theoretical and practical part At its beginning, the theoretical part deals with an general description of the transformer and its connection. Focus is given to aspects of the life of the transformer insulation system (oilpaper). Further, the technical diagnostics is analyzed, with description of quantities of gasliquid chromatography, the oil condition and condition of conductor insulation. Another important part of the thesis consists of an expert system, which is described generally from the past to the present. Characteristics, types and structure of expert systems are mentioned here, with its advantages and disadvantages. The practical part starts with a description of the data file, which is further used in the thesis. Main practical part is divided into three parts - the results of gas-liguid chromatography, selected results and expert systems. In the section entitled "Results of gasliquid chromatography", there is an analysis of selected properties of time series and temperature dependency of gases. Moreover, the methods of the ratios of gases such as Duval Triangle method are described. The second part entitled "Selected other results" shows the time dependency of variables and the neutralization number, along with the breakdown voltage dependency, and time of dependency, gas and moisture content in insulating oils. There is also a temperature dependency of moisture content dissolved in insulating oil discussed, as well as results of selected correlations, such as the correlation values of gas chromatography with state variables insulation of wires. The last part, "Expert systems", provides specific information about developed expert system. It describes the environment chosen for its development, followed by a description, features and verification of the expert system. Examples of the consultation results are included. All achievements of the individual parts are always summarized at the end of each section. The thesis contains chapters "Objectives of the work" and "Conclusion". The most important chapter is "The contribution of the work." It contains original work results and the results applicable in industry.

The aim of this thesis is to analyse the development of economic activity of persons aged 55 or older in the period from 2005 to 2014 and their position in the labour market in the Czech Republic, Greece and Sweden. In addition to the definitions of terms related to demography, economics and social policy, the thesis examines the factors influencing the employment of older people and the EU's approach towards the increasing proportion of the older population in the workforce. Further, it provides an analysis of the position of older people in the labour market. The analysis based on the employment rate and unemployment rate indicators shows that the situation of older workers in the labour market differs in the selected countries.

Novák, Jiří ; Vltavská, Kristýna (advisor) ; Šimková, Martina (referee)
The aim of this bachelor thesis is to analyse the economic development in the Czech Republic in the period from 1970 to 1989. Firstly, bachelor thesis defines the basic terms such as gross domestic product and clarifies the methodology of the material product system and the system of national accounts and their relationship. Secondly, it informs about the total employment development and the labour productivity. The data source of this thesis is the Federal Statistical Office and the Czech Statistical Office before 1989, which were processed in a project by the Department of Economic Statistics of the University of Economics Prague. This project was focused on the historical dated GDP data and its components in ESA 2010. Long dated macroeconomic indicators data contribute to economic research and give valuable outputs for further statistical analysis and forecasts. The main output of this thesis is the gross domestic product counted in the system of national accounts methodology and its following indices of the economic circumstances. Moreover, these outputs are presented with the data of the Czech statistical office from 1990 to 2014.

Filikarová, Zuzana ; Šimková, Martina (advisor) ; Fučíková, Simona (referee)
The aim of my bachelor's thesis is to provide an overview of a birth rate development in the European countries - in the Czech Republic, France and Sweden in a period of 20 years (1990 - 2010). The work includes individual characteristics of the state social policy of the population, history of the birth rates and a demographic projection for a future. The thesis is an attempt to outline the potential improvement of social policy with a focus on a family policy, so that the population drop of the Czech republic's citizens might be avoided in the future. Furthermore, the development of countries family policies where the birth rate is on a desired level and from which the Czech Republic could draw the inspiration is described. The conclusion of the thesis contains several suggestions how the family policy could develop in the future.
