Váňa, Tomáš ; Vítek, Martin (referee) ; Smital, Lukáš (advisor)
This master‘s thesis deals with biometric fingerprint liveness detection. The theoretical part of the work describes fingerprint recognition biometric systems, fingerprint liveness detection issues and methods for fingerprint liveness detection. The practical part of the work describes proposed set of discriminant features and preprocessing of fingerprint image. Proposed approach using neural network to detect a liveness. The algorithm is tested on LivDet database comprising real and fake images acquired with tree sensors. Classification performance approximately 93% was obtained.

The role of elections in non-democratic regimes: the case of Czechoslovakia before 1989
Piňosová, Barbora ; Váňa, Tomáš (advisor) ; Mlejnek, Josef (referee)
The theme of this bachelor's thesis is the role of elections in non-democratic regimes, by focusing on the election held in 1971 in communist Czechoslovakia. This work explores the classification of Czechoslovakia on the scale of non-democratic regimes, by using the non-democratic elections theory and acknowledging the specifics of the given period in the analysis of this particular election. The objective of this work is to answer the question of why the regime had to organise non-democratic elections and whether these elections served to legitimise the regime's power or perform more functions. Based on this analysis, the author concludes that the communist regime held the elections in order to finalise its consolidation process in response to the events of the Prague Spring. This was not only to legitimise its power, as it was particularly shown during the pre-election period that several significant functions were serving especially to reinforce the feeling of apathy and hopelessness among the population, which enabled the regime to survive until its collapse in 1989.

The concept of consciousness its components and functions in the process of system functioning in the understanding of Karl Wolfgang Deutsch
Pulicar, Miroslav ; Váňa, Tomáš (advisor) ; Franěk, Jakub (referee)
This bachelor thesis deals with the concept of political consciousness in the understanding of the German political scientist and international relations theorist Karl Wolfgang Deutsch. In the first, theoretical section it introduces some existing approaches and conceptualizations of consciousness in political science. Consequently, it provides an essential introduction to Deutsch's communications theory, its basic points and some crucial concepts, such as information, feedback, memory, or will. The aim of this section is to outline the specifics of Deutsch's communication-based approach to the analysis of political systems and provide context for the main subject of this thesis. After general introduction it deals with the very concept of consciousness. Through the analysis of Deutsch's pivotal work The Nerves of Government it outlines theoretical foundations of his concept, defines its functions and significance within the political system, connects it with other concepts of Deutsch's theory and marks some differences compared to approaches of other political scientists. In the second, practical section theoretical considerations developed in the previous section are on the basis of qualitative research applied on the specific political system. The aim of the research is to explain some of the...

Všetíčková, Denisa ; Kunštát, Daniel (advisor) ; Váňa, Tomáš (referee)
The presented Thesis "Political Communication and Politainment in the Presidential Election in the Czech Republic in 2013" analyses political communication in the historically first presidential election campaign in the Czech Republic. I saw the presidential election as an opportunity to research a new platform of political communication that politainment is. The primary aim of the Thesis is to introduce this concept in the context of the current nature of political communication and at the same time to identify variables defining this phenomenon in the Czech environment. Analysis of the elements of politainment is performed on campaigns of the two most successful candidates aspiring for the office of the President of the Czech Republic - Miloš Zeman and Karel Schwarzenberg. I focused primarily on the television appearance of both candidates in TV debates broadcasted by Czech Television, which were the climax of the entire presidential campaign. I was interested in the content of communication of both candidates and the overall character of the debates. The Thesis answers the following questions: What is political communication and its role in politics? How does its form change over time? Does personalisation of election campaigns result in the emergence of politainment as a phenomenon of political...

Three Liberal Theories of Justice
Macháček, Jiří ; Šimsa, Martin (advisor) ; Váňa, Tomáš (referee)
The mail goal of this thesis is to introduce the modern theory of liberal justice with a focus on distributive justice. In addition, the author addresses the issue of value neutrality in the liberal state and the concept of equality in liberal theory. The author presents the concept of "justice as fairness" described by liberal political philosopher John Rawls. Afterwards his concept is subjected to criticism of other contemporary liberal philosophers Robert Nozick and Ronald Dworkin. The author briefly looks into coherence between mentioned philosophers and earlier representatives of liberal theory, as well as their non-liberal critics. The first chapter contains a list of thinkers and their contributions to the issue of justice and the social contract theory. The following three chapters concerns the interpretation of the concepts of three mentioned authors using critical analysis of their publications. In the fifth chapter are described concepts of thinkers who critically respond to Rawl's theory of justice generally reffered to as communitarians, including the conception of Jürgen Habermas. In the sixth chapter the author summarizes the main theoretical background and arguments of discussed liberal philosophers. Finally the thesis is concluded by their comparison and summary of key facts and...

Language and Totalitarianism
Váňa, Tomáš ; Mlejnek, Josef (advisor) ; Kučera, Rudolf (referee)
The diploma thesis Language and totalitarianism deals with the relation between these two phenomena. On the basis of key thinkers dealing with totalitarianism it formulates its own definition of totalitarianism. It presents the communication theory of Karl Wolfgang Deutsch, on which basis it points to the close relation between communication and political systems, concretely between language and totalitarianism. Language is analysed mainly on the thoughts of Ferdinand de Saussure and Ludwig Wittgenstein. Totalitarian language is explained using mainly Orwell's totalitarian language newspeak in 1984. A practical analysis of a sample of Rudé právo form the era of the communist regime in Czechoslovakia in the years 1948-1989 shows its manifestations in real use. At the end of the thesis political correctness is introduced as an example of totalitarian tendencies in liberal democracies.

The birth of The Economist
Váňa, Tomáš ; Köpplová, Barbara (advisor) ; Jungová, Eliška (referee)
Bachelor thesis "The birth of The Economist" deals with the birth and evolution of the weekly newspaper The Economist. That is from 1843, when it was founded, to 2007, when John Micklethwait became its editor. The main emphasis is laid on the birth of The Economist. The atmosphere of those times, the social situation in England in the middle of the nineteenth century and the pass and repeal of the Corn Laws is dealt with in order to describe the birth of The Economist more accurately. The situation at the media market is also described. A part of the thesis is dedicated to the economical thinking of Adam Smith, Thomas R. Malthus and David Ricardo. And to the doctrines of laissez-faire and free trade, which were the main motive, or more specifically their pursuit, for the foundation of The Economist. A longer part of the thesis is dedicated to the lives and personalities of the founder of The Economist James Wilson and his son-in-law Walter Bagehot, who was the third editor of The Economist. These two men are the most important figures in the history of The Economist, and have contributed like nobody else to its development. A part of the thesis is describing the first numbers of The Economist and its readers, supporters and opponents. The last part of the thesis is dedicated to a brief description...
