Assessment of investment in heating house
Zdražil, Pavel ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
The bachelor´s thesis deals with economic evaluation of investment in insulation and heating and resulting operation of boilers in a family house. The calculation of thermal design power, which is needed for heating, was made according to norm ČSN EN 12831 for the house in actual state without insulation. Further were suggested two options of insulations and modernization of windows, for reduction of heat loss. Then was calculated the thermal design power for the two new options, again according to norm ČSN EN 12831. Next were presented possibilities of heat sources. For the specified family house was chosen a gas boiler in classical and condensing implementation for all three variants of insulation. These all options have made six variants which were compared together and evaluated. In the conclusion were excluded four variants economically disadvantageous and was chosen one of the final two variants as the best suggestion for the specified family house.

Gobblet game from the point of artificial intelligence
Kotrč, Pavel ; Majerech, Vladan (referee) ; Vomlelová, Marta (advisor)
Gobblet is a new abstract board game, rules of which are based on the classic 4-in-arow game played on 4×4 board. However, the ability to gobble up and move the pieces on the board greatly increases its complexity and Gobblet is thus comparable to games like Checkers or Othello. That makes it interesting from the artificial intelligence point of view. This thesis explores the possibilities of classic and more recent methods for searching the Gobblet game tree - the minimax algorithm, alpha-beta pruning, a heuristic for move ordering, iterative deepening and others. The resulting algorithm is compared to the computer players on the Boardspace game server where it plays above-average with the best-playing robot. Implementation of all described algorithms and a graphical user interface for testing them in the Java programming language is an inseparable part of this thesis.

Logic, form and argument
Nevrkla, Svatopluk ; Jirků, Petr (advisor) ; Gahér, František (referee) ; Šefránek, Ján (referee)
The goal of this thesis is to defend and explain the claim that traditional logical analysis is not the best tool for studying natural language argumentation. The most common critique directed at employment of logical formalisms as tools for analysis of the natural language is usually based on pointing out of differences between structure and semantics of natural languages and languages of logical formalisms. This is not the main issue, I believe. According to my findings the most fundamental problem of the traditional analysis is that it is based on many problematic epistemological assumptions, which are inherited from empiricist-positivist tradition. Namely the positivist version of the classical model of rationality as deductive reasoning from some basis of immediately verifiable and therefore unquestionable knowledge. The doctrine that every reasonable argumentation is reducible on deductions of such kinds is supposed to justify the traditional analysis of argumentation. My original contribution is mainly in showing that without abandoning those presuppositions, we cannot hope to arrive at better understanding of natural language argumentation by developing new and more precise logical formalisms. Logical formalisms are mere tools, which we have to use for the right purpose in the first place....

300 Years of the French Horn in Czech Lands
Ratajová, Tereza ; Gregor, Vít (advisor) ; Brábek, Ladislav (referee)
Author's precis The goal of my bachelor thesis is to chart the whole history of the French horn in the area of the Czech Republic. After an introduction of the origin of the instrument my thesis begins in the end of the 17th century when the first horns where brought to the Czech country thanks to The Count Špork. My first chapter describes the progress of the instrument in the literature which was written for the French horn and the first use of the French horn. I described the historical context of that epoch. The description in the second chapter is of the development of the instrument and the events connected with it, similarly as in the previous chapter, but it is situated into classicism. This chapter deals with the theme of transposition and with the significant horn players of Czech origin, particularly with Stich Punto. The end of the chapter is about composers who composed for horn in the era of classicism. The third chapter concerns the development of the instrument in the era of romanticism. It deals with the Prague conservatory from its founding up until now. The last part of the thesis offers the readers a list of the best Czech horn players of the 20th and 21st centuries. In my thesis I tried to describe the evolution of the instrument in detail and put it in context with socio-cultural...

Jiří Frejka at the Karlín theatre 1950-1952
Bár, Pavel ; Just, Vladimír (referee) ; Herman, Josef (advisor)
Jiří Frejka integrated the tenets of avant-garde, classical drama and poeticism. He entered the Karlín Theatre (at that time the Theatre of Czechoslovak State Film in Karlín) to direct the play "Nebe na zemi" by Jiří Voskovec, Jan Werich and Jaroslav Ježek in autumn 1950, after he was pushed off his post as the art chief of the Vinohrady Theatre (for political reasons). Inspite of this forced move he immediately started working on the development of the Karlín Theatre. He invited the contemporary first class artists to cooperate - the composer Václav Trojan, the choreographer Saša Machov, the poet Vítězslav Nezval or the set designer František Troster. Five peďormances which Frejka directed during his short work are some of the best and most successful those have ever been created in the Karlin Theatre. Although he had to give in to the demands of the regime of that time and he had to present plays from the Soviet Union ("Akulina", "Keto and Kote"), he also managed to present idyllic plays - "Paní Marjánka, matka pluku" by Josef Kajetán Tyl, or versicular "Schovávaná na schodech" by Vítězslav Nezval. Meanwhile he was trying to introduce the actors to a synthetical, leťs say musical-like acting - for the sake of the education of these "singing actors" he wanted to establish a new department ofmusical comedy...

EVALUATION OF POSTERIOR CAPSULE OPACIFICATION AMONG VARIOUS TYPES OF INTRAOCULAR LENS
Pozlerová, Jana ; Jirásková, Naďa (advisor) ; Těšínský, Pavel (referee) ; Synek, Svatopluk (referee)
Purpose: To evaluate posterior capsule opacification (PCO) in patients 7 years after cataract operation with the implantation of three types of intraocular lenses (IOL): rigid polymethylmetacrylate IOL (PMMA) with a round optical edge, foldable hydrophobic acrylate IOL with a sharp edged optic and foldable IOL whose optical part is made from silicone with round edges. For the quantification, two computerized methods were used and the correlation of the two systems was evaluated. Data from both methods were used to compare PCO incidence for the followed IOL and ascertain if some type of IOL showed better qualifications in the prevention of posterior capsule opacification. Patients and methods: We evaluated 73 patients that had undergone cataract operation using the classic ultrasound phacoemulsification method in the time period of 1998-2000 at the Ophthalmology Department of the Hradec Kralove Faculty Hospital. Seven years after the operation, a standard ophthalmologic examination was performed including best corrected visual acuity (BCVA) and a digital photograph of the anterior segment of the eye in mydriasis, focusing on the posterior capsule. On the photograph, posterior capsule opacification were evaluated using the Evaluation of Posterior Capsule Opacification 2000 software (EPCO 2000) and the...

Panýrková, Lucie ; Dolanská, Nora (advisor) ; Kopecký, Ladislav (referee)
The subject of this bachelor thesis is from the field of tourism, concretely the support of domestic tourism in the Czech Republic. The first part is a theoretic introduction into the topic of services marketing, which differs a lot from the classic goods marketing. The next part contains a summary of the current state of domestic tourism in the Czech Republic. The main part of the thesis, however, focuses on activities, which were performed in year 2009 and 2010 to support domestic tourism, from creating of a logo and an advertising slogan for the Czech domestic tourism, to a contest for the best tourist activity. Most of the attention was given to the Tips for Trips project. The thesis compares the current and the previous versions of the web portal www.kudyznudy.cz, assesses the project's activities on the Facebook social network and it also describes the Tips for Trips publishing activities and annual Tips for Trips contest. In 2010 the project was supported by a large advertising campaign, which is also mentioned in the thesis. There is a detailed analysis of television sport and printed advertising, along with evaluation of the campaign's effectiveness. The last chapter is dedicated to an online survey, which I carried out with the aim to map the public's opinion about the domestic tourism in...

Methods of volatility estimation
Hrbek, Filip ; Witzany, Jiří (advisor) ; Fičura, Milan (referee)
In this masterthesis I have rewied basic approaches to volatility estimating. These approaches are based on classical and Bayesian statistics. I have applied the volatility models for the purpose of volatility forecasting of a different foreign exchange (EURUSD, GBPUSD and CZKEUR) in the different period (from a second period to a day period). I formulate the models EWMA, GARCH, EGARCH, IGARCH, GJRGARCH, jump diffuison with constant volatility and jump diffusion model with stochastic volatility. I also proposed an MCMC algorithm in order to estimate the Bayesian models. All the models we estimated as univariate models. I compared the models according to Mincer Zarnowitz regression. The most successfull model is the jump diffusion model with a stochastic volatility. On the second place they were the GJR- GARCH model and the jump diffusion model with a constant volatility. But the jump diffusion model with a constat volatilit provided much more overvalued results.The rest of the models were even worse. From the rest the IGARCH model is the best but provided undervalued results. All these findings correspond with R squared coefficient.

Modelování portfolií s risk faktory s těžkými chvosty
Kyselá, Eva ; Málek, Jiří (advisor) ; Fičura, Milan (referee)
The thesis aims to investigate some of the approaches to modelling portfolio returns with heavy-tailed risk factors. It first elaborates on the univariate time series models, and compares the benchmark model (GARCH with Student t innovations or its GJR extension) predictive performance with its two competitors, the EVT-GARCH model and the Markov-Switching Multifractal (MSM) model. The motivation of EVT extension of GARCH specification is to use a more proper distribution of the innovations, based on the empirical distribution function. The MSM is one of the best performing models in the multifractal literature, a markov-switching model which is unique by its parsimonious specification and variability. The performance of these models is assessed with Mincer-Zarnowitz regressions as well as by comparison of quality of VaR and expected shortfall predictions, and the empirical analysis shows that for the risk management purposes the EVT-GARCH dominates the benchmark as well as the MSM. The second part addresses the dependence structure modelling, using the Gauss and t-copula to model the portfolio returns and compares the result with the classic variance-covariance approach, concluding that copulas offer a more realistic estimates of future extreme quantiles.
