Acceleration of Burrows-Wheeler Transform Using GPU
Zahradníček, Tomáš ; Drábek, Vladimír (referee) ; Šimek, Václav (advisor)
This thesis deals with Burrows-Wheeler transform (BWT) and possibilities of acceleration of this transform on graphics processing unit (GPU). Methods of compression based on BWT are introduced, as well as software libraries CUDA and OpenCL for writing programs for GPU. Parallel variants of BWT are implemented, as well as following steps necessary for compression, using CUDA library. Amount of compression of used approaches are tested and parallel versions are compared to their sequential counterparts.

Václav Majer and the Social Democratic Party. The Fortunes of the Leading Figure of One Stream within the Czechoslovak Social Democracy
Brož, Jan ; Kocian, Jiří (advisor) ; Zahradníček, Tomáš (referee) ; Horák, Pavel (referee)
The present thesis deals with the political career of a Social Democratic politician Václav Majer. No specialized paper has so far been dedicated to his fifty-year-lasting career, even though his position in history of the Czechoslovak Social Democratic Party is far from negligible. Václav Majer is particularly known as a leader of the "right"/anti-communist wing within the Social Democratic Party during a short spell of Czechoslovak history from 1945 to 1948 (so-called Third Republic). However, he had started his career much earlier at the beginning of the First Czechoslovak Republic in Louny District. In mid-thirties he had moved to Prague and kept on working after the Munich Agreement was signed, and during the Protectorate as well. At the beginning of 1940 he emigrated to the United Kingdom. During the Second World War he has started his career in high level exile politics in London. After the Communist coup d'état in 1948, which had ended the period of the Third Republic, Majer left Czechoslovakia again. He lived and worked in exile till his death. Attention is paid to Majer's position on political scene and to development of his relations with other political actors. My research is based on study of archival documents, as well as study of specialized books, memoirs, newspapers and periodicals.

Polish Workers in Czechoslovakia: Unwelcome Friendship: Specific features of temporary labor migration in the socialist system
Klípa, Ondřej ; Kučera, Jaroslav (advisor) ; Uherek, Zdeněk (referee) ; Zahradníček, Tomáš (referee)
Dissertation Title Polish Workers in Czechoslovakia: Unwelcome Friendship Specific features of temporary labor migration in the socialist system Author Ondřej Klípa Summary The aim of the dissertation is to study the case of Polish workers in Czechoslovakia who were employed on conditions set by intergovernmental treaties. Most of them were women. This case had two specific features. First, it was highly regulated by both of the co-operating states. Second, the state bodies tried to control intensively both the workers in order to isolate them from local population and the public discourse of this topic. In this study I argue that both of the features arise from fundamental elements of socialist system, which are "economy of shortage" and totalitarianism. These elements were identified in the work of Hungarian economist János Kornai. Instead of totalitarianism as a coherent concept I use only certain totalitarian practices that were exercised with variable intensity, depending on circumstances. In the dissertation I examine causality between these two fundamental elements (independent variables) and both regulation and control (dependent variables). For this purpose I consider the studied case as a specific model of temporary labor migration in socialist system. The case is also situated in a broader...

Czechoslovak TV in the time of Perestrojka: Public Diskussions in the late 1980s
Machát, Zbyněk ; Pullmann, Michal (advisor) ; Zahradníček, Tomáš (referee)
This thesis is called "Czechoslovak Television in the Period of Perestroika: Discussion Programs in the Late 1980s" and it attempts to add its bit to the research of the complex mosaic of late socialism in former Czechoslovakia. Television is not a topic standing in the limelight of historiographers' interest. However, the reasons for this thesis are clear - in the 1970s, television has become a dominant information channel in the Euro-Atlantic space. The thesis wants to draw attention to the significant phenomenon affecting society in the second half of the twentieth century - role of the mass media and their contribution to creating public space. With help of contemporary concepts of Jean Baudrillard, Jürgen Habermas, and Bruno Latour, the thesis tries to answer the question: what is television? The thesis maps the efforts and development of promoting television in Czechoslovakia and focuses on selected programs from the late 1980s. These programs contributed to reconstitution of public space as a place of articulation of specific interests of various social groups, mostly through public debate or conflict. In order to understand the change that these programs brought, the thesis attempts to reconstruct contemporary discourse on a wider pallet of resources than just television programs. These are...
