Photovoltaic, as an alternative source of electricity
Floková, Kateřina ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The aim of this work is to provide a description and an explanation of the process of obtaining elektrical energy from solar radiation. There is preliminary mentioned an importance of producing electrical energy from renewable sources and development of photovoltaic systems. The body of the thesis is divided into seven chapters. At first, there is described the principle of transformation solar radiation into electrical energy. Then, the description of types of barrier-layer photocells follows. The types are divided according to their structure and material, which are they produced from. The third chapture is focused on production and construction of photovoltaic modules. Ways, how can be production of electricity increased, are mentioned in the fourth chapture. Advantages and disadvantages of solar concentrators are given there. In the fifth chapture there are described two basic kinds of connection of photovoltaic system. Different ways of taking-off produced electricity are related with those kinds of connection. The last chapture is the fundamental chapture of the thesis. There is given a project of concrete photovoltaic system. For this system is calculated economic return of investment included supposed increase of prices of electricity. In conlusion the author noticed events that would be given and emphasized the outcome of concerete project of photovoltaic system.

FTTx access networks
Hladký, Miroslav ; Filka, Miloslav (advisor)
This graduation thesis addresses questions of deriving benefits from the FTTx optical access network. This project is divided into four main subject surveys. First part contains familiarization with individual architecture of FTTx network, topology of network and the use of components in these access networks. Second part shows how ideal optical access network is for distribution of modern multimedia services which pose great demand on the width of transmission band. It also shows success and trend growth of integration of the optical network into access segment in the Czech Republic and the rest of the world. The choice of right proposal and follow-on project of FTTx optical access network in assigned location is described in part three. It also compares investment costs needed for implementation of these proposals. Final part of this project shows financial budget and return of investments of a proposed access network. It also includes a contemplation of optical access network’s development.

Business Plan of Development Entrepreneuship
Majlišová, Simona ; Ing.Peter Tkáč (referee) ; Bartoš, Vojtěch (advisor)
The present dissertation is the design of a company's business plan, with a view to the construction of a servis, with all the important factors such as economic and non-economic factors, and legislative changes in the branch taken into consideration. Last but not least, the economic standing of the company is also evaluated. The project is simultaneously assessed from the viewpoint of potential implementation of the proposed solution.

Assessment of the Impact of Thermal Insulation Performance of the Primary School in Dobruška on its Running Expenses
Marešová, Jana ; Bittner, Oldřich (referee) ; Klika, Pavel (advisor)
My diploma thesis is foceused on evaluation of return of the investment based on the laster insulation together with the filling of the open space and the usage of the back gained heat. For my calculation I used the real building of the basic school Františka Kupky in Dobruška. It is a typical building extended to the whole area of Czech Republic. The realization of the building was finished in 1994. I deal with more variants of more widths of the insulation system in my work. In every single draft is counted with costs for buying of the insulation and the exchange of the filling of the opern spaces. Every draft is counted with the usage of the back gained heat. The biggest benefit was found in the insulation of the 180 mm perimeter wall and the 280 mm of the roofing sytem. Windows and door had the same number of the heating 0.8 W/m2k. In the experimental calculation with the most advantages the conclusion was made that on the heat loss of thr object is the most influential the filling of the open spaces and the facilities for the back gained heat, too. Because it is a typical building, my diploma thesis could work as a background for the draft of the elimination of the heat loss at the buildings with the same shape and usage.

Entrepreneurial Intention of Business Development
Zukal, Vít ; Trestrová, Martina (referee) ; Bartoš, Vojtěch (advisor)
Master’s thesis focuses and analyses the present state of production company and includes entrepreneurial intention of business development. The first part of my work focuses on theoretical introduction, definitions of basic concepts and methods to be used. The second part analyzes the current situation in terms of general and major environment, proposes solutions, financing options, including an assessment of return of implementation.
