Application of modified Steiner tree problem on the electricity distribution network in the Desertec project
Vyoral, Martin ; Fábry, Jan (advisor) ; Jablonský, Josef (referee)
The aim of the thesis was minimize the planned cost of construction of the electricity network in North Africa and the Arabian peninsula between solar power plant in Desertec project. The work is divided into three chapters. The first chapter is devoted Desertec concept, its key technologies, benefits and barriers. Another chapter is devoted to the theory of graphs. It consists of an introduction to graph theory, minimum spanning tree and Steiner tree. The third practical chapter is devoted to reduction of the initial projected cost of constructing Electric Supply network using Steiner tree and its modifications. It also addresses the issue of valuation of edges and nodes to which it is necessary to include a number of factors such as energy capacity to be transmitted, the type of transmission medium, environmental conditions, geomorphological aspects and other safety regulatory requirements.

Nonparametric estimations in survival analysis
Svoboda, Martin ; Malá, Ivana (advisor) ; Tomášek, Ladislav (referee)
This work introduces nonparametric models which are used in time to event data analysis. It is focused on applying these methods in medicine where it is called survival analysis. The basic techniques and problems, which can appear in survival analysis, are presented and explained here. The Kaplan -- Meier estimator of survival function is discussed in the main part. This is the most frequented method used for estimating the survival function in patients who have undergone a specific treatment. The Kaplan -- Meier estimator is also a common device in the statistical packets. In addition to estimation of survival function, the estimation of hazard function and cumulative hazard function is presented. The hazard function shows the intensity of an individual experiencing the particular event in a short time period. Special problems occur when analyzing time to event data. A distinctive feature, often present in such data, is known as censoring. That is the situation when the individual does not experience the event of interest at the time of study. The thesis covers also an empiric part, where the results of an analysis of patients with the larynx carcinoma diagnosis are shown. These patients were treated in a hospital located in České Budějovice. This analysis is based on a theory presented in the previous chapters.

Comparison of the Slévárna Losenický and the Slévárna a strojírna companies based on solvency and bankruptcy models
Zázvorka, Tomáš ; Strnad, Lucien (advisor) ; Schönfeld, Jaroslav (referee)
This bachelor thesis is aimed at comparison and evaluation of financial health of the Slévárna Losenický s.r.o. and the Slévárna a strojírna, a.s. companies based on financial analysis application, particularly solvency and bankruptcy models, in the years 2004 - 2008. The bachelor thesis also deals with the explanatory power of the models. Both of the selected companies differ deliberately in their business success. The first mentioned one seems to be prosperous, while the second mentioned one has been undergoing insolvency proceeding since September 2009, but both of them are from the same branch of business and comparable with their amount of sales. In the theoretical part the bankruptcy theory, some elementary methods of financial analysis, i.e. horizontal and structural analysis, main financial ratios and net working capital indicator, are described first and then the extra attention is devoted to the solvency and bankruptcy models including their construction and evaluation criteria. In the practical part the mentioned methods and models are applied to both the selected companies and in the conclusion the explanatory power of applied solvency and bankruptcy models is evaluated.

Capital structure of Czech joint stock companies and its determinants
Poulová, Lucie ; Marek, Petr (advisor) ; Hrdý, Milan (referee)
The aim of this thesis is to perform an analysis of capital structure of joint stock companies based in the Czech Republic. The first part of the thesis introduces modern theories and main determinants of capital structure. Further it stakes out basic models used for testing the validity of mentioned theories and the methodology used. The second part of the thesis focuses on practical results of the analysis. The first chapter summarises descriptive analysis of the passive structure, the level of leverage, the composition of equity and liabilities of the joint stock companies. These ratios are judged mainly according to industry classification and the type of ownership. In the next step, the relationship between leverage and profitability is closely explored since it is thought to be one of the main determinants. In the last chapter, the models are applied to the sample of Czech companies with the effort to judge the validity of capital structure theories and to evaluate the effect of determinants on capital structure.
