Economic comparison of light sources
Růžička, Josef ; Motyčka, Martin (referee) ; Štěpánek, Jaroslav (advisor)
This bachelor thesis deals with the economic comparison of light sources. On the market there is currently no physical quantity that would enable the light sources to be compared from an economic point of view in long-term perspective. The main objective of the work is, therefore, by calculations of the specified (or directly measured) parameters of the light source to provide a uniform total cost of lighting, thanks to which it will then be possible to sort the sources according to the price benefit. Evaluation is based on measurements of 28 light sources from different groups: the classical bulbs, halogen bulbs, compact fluorescent bulbs, compact LED retrofits and dimmable LED retrofits with color-changeable modes. These light sources are meant to be used for indoor home lighting, offices, halls, etc. The final part of the paper clarifies what kind of light sources and for what reasons they are the most profitable and have the greatest potential for the future. There's also a comparison of theoretical parameters provided by the manufacturer, and parameters directly measured in the laboratory and the evaluation of the deviations between them. The use of this thesis comes from provision of the calculation structure to a user who will better understand the topic of costs while purchasing the light source. Well arranged description and information about the light sources in theoretical part of the thesis is another utility to be mentioned.

Measurement of directional non-uniformity of the correlated color temperature of LED luminaires for road lighting
Růžička, Josef ; Škoda, Jan (referee) ; Motyčka, Martin (advisor)
This master's thesis deals with the topic of correlated color temperature measurements. There has been an increase in the demand for accurate correlated color temperature measurements due to regulations concerning reconstruction of the street lighting made by Department of Industry and Business. The main objective of this work is to determine which measuring devices and methods would make correlated color temperature measurements to be done in the most accurate and practical way. The evaluation is based on five laboratory measurements and two outdoor measurements. The main subject of these measurements is biodynamic LED lamp Tungsram SLBt. A verification of certain output data as well as simulating situations that would be too difficult to measure is made by an algorithm created in Matlab software. Final part of the thesis deals with the accuracy differences among various correlated color temperature measuring methods. It describes advantages and disadvantages of these methods and proposes ideas for consequent inquiry. This thesis finds its use in correlated color temperature measurement error and uncertainty discoveries that will have to be dealt with in the future. Also, theoretical part of the thesis may be used as lighting technics learning material.

Subpixel approach for vegetation classification from hyperspectral and multispectral data in the Krkonoše Mts. tundra
Růžička, Josef ; Kupková, Lucie (advisor) ; Červená, Lucie (referee)
This diploma thesis focuses on the possibilities and potential of using subpixel-based classification methods for hyperspectral and multispectral data capturing selected localities of the tundra in the Krkonoše Mountains, specifically the Bílá louka meadow and Luční hora mountain areas. The thesis presents current methods for collecting and using endmembers as well as methods for the classification itself using the spectral unmixing approach, mainly in connection with the classification of heterogeneous vegetation communities. In the practical part of the thesis, various methods of collecting end members are used, especially the extraction of end member spectra directly from image data using manual, semi-automatic and automatic methods. Envi, EnMAP-Box 3 and MATLAB software are used for collection and subsequent classification. Endmembers collected in different ways are then combined with different classification methods in an attempt to achieve the most accurate result possible, which would be at the level of controlled pixel-based classification. The classification took place on two legend levels. Detailed, classifying individual plant species and less detailed, where species are aggregated into larger groups. The best results were achieved by the classification of the Bílá louka meadow...

Proposal on the optimal basketball training method within the physical education of children in older school age
Růžička, Josef ; Pokorný, Ladislav (advisor) ; Kuhnová, Věra (referee)
Title: Proposal on the optimal basketball training method within the physical education of children in older school age Author: Josef Růžička The study aims to find optimal theoretical model of basketball training method within the course of physical education at primary schools and general secondary schools. We focus on children in older school age. The objective is to make basketball training more effective as well as more familiar to teachers that are lacking more complex or personal experience with this sport. We use the method of experiment. First, the numbers of testing exercises to detect the level of general game skills of the children were defined. Then the model of teaching method consisting of ten setting-up (introductory) exercises was developed and implemented into a complete semestral plan. At the beginning of experiment, two groups of children were tested for their general game skills. Then our proposed model was applied onto these two groups. We aimed to develop model of teaching that would help to improve and develop basketball skills of children. At the end of experiment period were children's basketball game skills tested again to see what extend was our proposed model successful. The results proved that proposed method of teaching was appropriate, since both groups of children...

What Drives the Sovereign Bond Spreads in Central and Eastern Europe?
Růžička, Josef ; Baxa, Jaromír (advisor) ; Paulus, Michal (referee)
This thesis is devoted to spreads of sovereign bonds in central and eastern Europe relative to German government bonds. In the first part, a widely used government bond spread model is presented. It turns out that its assumption may be relaxed. Next, we show how spreads, inflation and exchange rates interact. Subsequently, we investigate the relationship between spreads and other macroeconomic variables by econometric methods. The most important factors affecting bond spreads in the region are public debt, GDP growth, openness of the economy, current account balance, and inflation. Bond markets in CEE put more weight on total level of public debt than on budget deficits. The effects of these variables differed before and after the year 2008. Two subgroups of central and eastern European countries with similar spread determinants were identified: the first group is formed by Lithuania, Poland, Slovakia, and Slovenia, while to the second one belong Bulgaria, Hungary, Latvia, and Romania. Uncertainty on global financial markets increases bond spreads in CEE as well as in western Europe. Bond spread determinants of the two groups differ from those of western European countries.

Taxation of the provision of contributions to share capital and outside share capital and taxation of these deposits
Růžička, Josef ; Vondráčková, Pavlína (advisor) ; Novotný, Petr (referee)
Taxation of the provision of contributions to share capital and outside share capital and taxation of these deposits - Abstract This diploma thesis describes the basic tax context in the case of deposits in the company and withdrawals from the company always in connection with equity. The diploma thesis focuses on domestic legal entities. It does not describe the connection with deposits in foreign companies. The diploma thesis is based on the domestic tax system. This system includes the following resources. Domestic regulations (laws that are affected by the so-called transcription of EU directives), international contracts (contracts of prevention of double taxation), domestic case law, and legitimate expectations outside the aforementioned sources. Legitimate expectations consist mainly of conveys from General Financial Directorate and minutes from the Coordinating Committees. The result of the performed analysis of documents is a summary of the basic tax context. The tax context includes the registration obligation (especially Value-added tax on the plant deposit), the notification obligation for payments abroad and the settlement of withheld tax. The key tax for non-monetary deposits is Value added tax. Non-monetary deposits by type are considered to be a service or goods according to ZDPH. The key...
