Efficiency analysis of green buildings operations
Muškát, Petr ; Dvorská, Michaela (referee) ; Ivanička, Koloman (advisor)
The main topic of my bachelor’s work is comparison heating costs of a family double house with original wall fillings and after applying external insulation including additional saving measures. My work is taking in count a possibility of applying for financial grant organised by European Union. This grant is called Green for savings and it is a helping tool leading to energy savings and modernization of old buildings. Next part is focused on used materials in nowadays for building revitalization and reconstructions. These materials has to meet high standards and criteria in thermo-insulation combined with simple construction solution. Manufacturers in these days tend to raise the quality of their products to maximal possible level.

Evaluation of Construction Project from aspect of Whole Life Costs
Foitlová, Lucie ; Holá, Michaela (referee) ; Hromádka, Vít (advisor)
The theoretical part deals at the beginning with evaluation of effectiveness of the project, as well as with the information about individual stages of the life cycle of the building, wear and tear of the buildings, lifetime of the elements and whole life costs of the building that are of particular interest to the investor. In conclusion, there are mentioned wastes and emissions. The thesis is completed by a case study of the family house where the whole life costs of the building life cycle are solved.

Economics aspects of building and operation of heat power plant utilizing biomass
Špinar, Marek ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
This work builds on a semester project where they were processed by the first two points of tasks, this the issue of the use of biomass in energy and needs quantification of biomass for energy production plant defined performance. Now the work is devoted to comparing plants using heat energy from biomass economically and possible future developments respectively. Recommendations for construction. Prior to the issue of technology are addressed aspects related to the implementation of production in terms of investment. Methods are provided solution investment opportunities and outlook on the implementation phase electricity works. The work is devoted to the assessment of value and comparison of different technologies to convert biomass into electricity. The paper compares the capital and operating costs of the considered types of power plants defined performance. The indicator is the ratio CZK / kWh. The important part is the processing recommendations for construction based on the information gathered. This section discusses the sources of electrical energy with a view to the future, therefore consideration of appropriate application of specific types of production with regard to regulation, for use as to the optimal mode of operation. At the end of the work is devoted to the issue of clean energy from biomass, which is the main point of interest in financial support from the state in the form of grants, which the state encourages individual entities in the construction of energy sources and bio establishments.

Photovoltaics in architecture
Bidlová, Jitka ; Kyselka, Mojmír (referee) ; Budkeová, Branislava (referee) ; Chybík, Josef (referee) ; Urbášková, Hana (advisor)
Nowadays there are more and more installations of renewable sources of energy. One of them is changing of sunlight into electric energy by using photovoltaic cells. Installation of photovoltaic systems into buildings and landscape is becoming modern approach to architecture and urbanism. It creates new architectonic expression - "solar design" and brings not only the energy profit but successful substitution for traditional materials and its usable properties.

The storage water plants problem appreciation
Archalous, Jakub ; Himr, Daniel (referee) ; Sloupenský, Zdeněk (advisor)
This bachelor’s thesis deals with the use of hydropower. It gives an overview of hydroelectric plants and describes mechanisms that convert water energy into electric energy. The most attention is paid to the principle and operation of pumped storage power plants and the machinery used there. Also the efficiency of the pumping cycle at Dlouhe Strane power plant is calculated.

Small scale photovoltaic system
Vaľočík, Jan ; Škvařil, Jan (referee) ; Pospíšil, Jiří (advisor)
The aim of this work is utilization of solar energy for electrical energy production focusing on photovoltaics. First, the principle, function and structure of photovoltaic cells is described. Then the current types of cells are introduced, followed by possibilities on how to increase the production of electrical energy from photovoltaic modules. Subsequently the connection methods between the photovoltaic systems and the network are discussed. The thesis is concluded by a design of a small scale photovoltaic system for a family house including an economic evaluation.

Emotional State Recognition and Classification Based on Speech Signal Analysis
Černý, Lukáš ; Atassi, Hicham (referee) ; Smékal, Zdeněk (advisor)
The diploma thesis focuses on classification of emotions. Thesis deals about parameterization of sounds files by suprasegment and segment methods with regard for next used of these methods. Berlin database is used. This database includes many of sounds records with emotions. Parameterization creates files, which are divided to two parts. First part is used for training and second part is used for testing. Point of interest is self-organization network. Thesis includes Matlab´s program which can be used for parameterization of any database. Data are classified by self-organization network after parameterization. Results of hits rates are presented at the end of this diploma thesis.
