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.
Fantasy map design by the literary works of A. Sapkowski
Růžička, Josef ; Čábelka, Miroslav (advisor) ; Lysák, Jakub (referee)
The work focuses on the design of the process of creating map of the fictional world. In particular focuses on the creation of the fantasy world of the Witcher by Polish author Andrzej Sapkowski. The importance of the map for a literary work is discussed. The world, based on selected author's work, is also compared to fictional worlds based on the literary work of other authors. The work also focuses on various possibilities of map creation. Maps of the Witcher world by another authors are also used as inspiration. Then one procedure is designed and used to create a fantasy map. It also includes comparing the selected world with the real world and finding similarities between them. Keywords: Fantasy map, fictional world, The Witcher, Andrzej Sapkowski.
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.
Proposal on the optimal basketball training method within the physical education of children in older school age

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...
