Anonymity in P2P Networks
Brunai, Adam ; Malinka, Kamil (referee) ; Barabas, Maroš (advisor)
Freedom of speech and the right to privacy are maybe the most important elements of a modern society, yet the rights are often violated. This fact was the main reason for writing this thesis covering P2P network models, anonymity, censorship resistance and their use in real P2P networks and publishing systems. We discuss their effectiveness and suitability for specific purposes, but also the security considerations of their use. The second part of this thesis presents the LSPP publishing protocol, which is an library implementation of an anonymous censorship resistant P2P network. Finally, we analyze the proposed protocol and compare it with existing solutions.

Crowd simulation
Řepka, Filip ; Pelikán, Josef (advisor) ; Horáček, Jan (referee)
In recent days, the number of reasons why to be interested in the topic of crowds of agents computer simulation is increasing. The field of activity and use of this element is spreading all the time. Whether public building projects testing, investigation of individual's impact on a crowd or replacing the crowd movie scenes participants by a computer simulated agents, the crowd simulation is well efficient and often needed. The thesis could be taken as a first step to creating of a common framework applicable for a wide range of situations. It stands out from a row of recent systems with a relatively narrow field of application thanks to its commonness.

Eufunction and dysfunction in theories of collective action
Kinská, Michaela ; Maslowski, Nicolas (advisor) ; Německý, Marek (referee)
In this work, we deal with theories of collective action. To categorize the researchers used information from the functionalist approach. The aim is to provide an overview of sociologists concerned with theories of collective action, i. e. various forms of collective action. Mainly for this work is the concept of function and its distribution eufunction and dysfunction as two poles. Researchers are closer to those poles. The inclusion of researchers in these poles are still dealing with other characteristics that unite and differentiate. In the first chapters of the thesis deals with the functionalist concepts and theories of collective action. The next chapter is already engaged functionalist categorization and other characteristics researchers. The chapter is divided into two parts, which correspond to two functionalist terms, i. e. eufunction and dysfunction. Keywords functionalism, collective action, eufunction, dysfunction, crowds, social movements, revolutions, R. K. Merton, T. Parsons
