Torrent Peer Monitoring
Bezděk, David ; Pluskal, Jan (referee) ; Polčák, Libor (advisor)
This master's thesis deals with analysis and implementation of methods for BitTorrent monitoring focusing on the Mainline DHT protocol. The aim of the thesis was to create a system, that will be looking for BitTorrent peers that participe in the illegal file distribution. Another task of the system was to collect and analyze data for counting size of the BitTorrent network. That was achieved by taking over of existing method. The system was designed and implemented as a module for monitoring of cybernetic crime. It also defines an interface for storing and sharing data, that provides data evaluation, easy data manipulation and serves for possible future extensions.

Change in the durability of concrete made of recycled concrete by alternative addition of ceramic admixtures
Stavař, Tomáš ; Hoffmann, Oldřich (referee) ; Stehlík, Michal (advisor)
The master thesis dealing with problematic about durability of concrete, with use of recycled concrete and addition of silica additions. Predominant for resistance of concrete constructions is surface layer, through which aggressive gasses and liquids penetrate from surrounding environment. The most important indicator of concrete durability is ability of surface layer transmissions of aggressive substants. In experimental part will be defined the actual state of surface layer by normal testing methods. The transmissions of surface layer will be tested on concrete cubes. Tests for transmissions of air (method TORRENT), of water (method ISAT), of acid gases (dept of carbonation by quick test in 98% CO2) will be carried out and also strength tests. Assessment of positive or negative influence of additions and amount of cement on durability and mechanical properties of concrete will be discussed in conclusion.

Analyzing BitTorrent Behavior
Horáček, Pavel ; Grégr, Matěj (referee) ; Matoušek, Petr (advisor)
This thesis is focused on analysis of the BitTorrent network, from theoretical view point by analyzing protocols used by this network, as well as practical view by inspecting individual clients implementing these protocols. The aim of this thesis was to develop a monitoring method used to detect communication used by this network. Due to possible illegal data sharing as well as unwanted usage of the network bandwidth, it's important for network administrators to detect this kind of communication. Another aim of this thesis was to familiarize the reader with real communication used by clients that implement protocols used in the BitTorrent network. This thesis contains descriptions of individual phases used in three selected clients, as well as three experiments performed with one of these clients.

Piece of music and its legal protection in relation to internet piracy
Jakubíček, Petr ; Spirit, Michal (advisor) ; Boháček, Martin (referee)
The thesis deals with contemporary author's law which is effective in Czech republic in relation to a piece of music and its legal protection. The goal of first chapters is to outline the crucial statutes concerning subjects as authors, executive artists and recording producers. A great deal of the thesis concerns with internet music piracy which results from a mass file-sharing. It also includes an evalution of current author's law and its efficiency in today's information society.
