Administration of DNS Servers for FreenetIS Project
Raška, David ; Janoušek, Vladimír (referee) ; Malčík, Dominik (advisor)
The goal of this bachelor's thesis is to introduce an alternative option of DNS servers management using graphical interface. In this thesis it is implemented a graphic user interface for DNS servers, zones and records management and connection of a DNS server to a network management system. ISC BIND 9 software is used as a DNS server and management interface is implemented to open-source project FreenetIS. Connection of both parts is made by a script, which continuously updates DNS configuration on a server.

Computer-Generated Music
Chmelka, Jakub ; Polok, Lukáš (referee) ; Fapšo, Michal (advisor)
This bachelor´s thesis deals with the problem of music composition by means of computers. The system uses artificial neural networks which learn the regularities of the chosen music genre from the recordings in MIDI format. In addition to the melody, this work places great emphasis on rhythm of newly created compositions. Besides the problem of neural networks, this work deals with the appropriate representation of input data and re-conversion into MIDI format. The system is implemented as a set of scripts mainly in the mathematical software Matlab.

Text Dependent Speaker Verification
Fux, Jan ; Glembek, Ondřej (referee) ; Matějka, Pavel (advisor)
The goal of this Bachelor's thesis was to design text dependent speaker recognition system. There were few systems tested for MIT database. This database contains recordings of 0.46s average length. Best case for recognition is to use a combination of DTW system using posterior probability estimation (posteriograms) as an output of Phoneme recognizer and acoustic SID system based on iVectors and PLDA (Probabilistic Linear Component Analysis). Fusion with Neural network gives the best results (EER). These are 17.84% EER for women and 16.38% for men. It's 49.9% relative improvement for women and 54.2% for men against acoustic recognition alone.

System for Recording Video from IP Videocameras
Travěnec, Jiří ; Michal, Bohumil (referee) ; Skokanová, Jana (advisor)
This diploma thesis focuses on multimedia streaming from IP cameras. Its main goal is to explain theoretical background of real-time streaming via computer networks, and describe development of a recording system. This recording system is meant to be used mainly in schools for lecture recording purposes. The thesis contains description on how a recording server application and web-based management system were developed. The theoretical part explains topics related to multimedia streaming, networking, and multimedia procesing, such as real-time streaming protocols, encoding, compression, network latency, network congestion and many others.

Session Monitoring and Accounting in IMS Networks
Karpíšek, Filip ; Ryšavý, Ondřej (referee) ; Matoušek, Petr (advisor)
This thesis describes protocols used in IP Multimedia Subsystem (IMS) networks. Freely available implementations of IMS system are described. The main goal is to describe design and implementation of a tool for analyzing communication between users and IMS system. The tool seeks and decodes signaling messages. These messages are analyzed for information about sessions which are necessary for session monitoring and accounting. Final gathered information are exported in a form of extended NetFlow/IPFIX records. We used open-source Open IMS Core implementation for building IMS network and creating test data. As endpoints we used another open-source application for Android OS called IMSDroid.

Management of Development Projects
Lněnička, Martin ; Kaláb, Tomáš (referee) ; Waldhans, Miloš (advisor)
The thesis analyses a development project of 21 houses in the village of Podolí u Brna, which was carried out by Kaláb – stavební firma, spol. s r.o. It provides a description of the company structure and focuses on some of their processes, such as risk analysis, investment decisions in the pre-investment project phase, project funding, planning, and time management based on time schedules. The text also takes a close look at all the steps that were taken during the implementation of the Podolí project, and zooms in on regular on-site records monitoring how much work has been actually done. Furthermore, the thesis brings an analysis of the current developer market in Brno, focusing in particular on latest developments in logistics, and office & residential construction. And last but not least, the thesis also observes how prices in the real estate market have developed over the last decade and how new residential units in the Czech Republic have been lately built.

The Use of Pareto Analysis in Streamlining Sales
Pinkava, Vojtěch ; Škrdlík, Miloš (referee) ; Bayerová, Vladimíra (advisor)
This diploma thesis deals with the employment of the Pareto principle in increasing the efficiency of the product range in a selected grocery outlet of the Brněnka chain. A methodology for the evalution of the offered product range has been created based on general knowledge and practical usage of the Pareto principle in scientific work. The methodology is applied on sale records of a selected store. The work includes suggestions of product range alteration based on application of the formed methodology.

Computer analysis of sport matches
Židlík, Pavel ; Balík, Miroslav (referee) ; Atassi, Hicham (advisor)
This work deals with the possibility of a fast football match analysis from audio part of record with the possibility of implementation of some methods for other than football matches as well. The first intention was concentrated on detection of whiz of the soccer whistle that has specific frequency in its specter, which is out of common speech frequency. After detection harmonic frequency , the attention was focused on the definition of whiz meaning. Referee was helpful with the issue as he informed me about the number of whiz styles and provided me with referential samples for whiz classification. Neural network with back propagation was used for definition of whiz meaning. Another subject for detection of important moments of the match was concentration on the commentator’s basic tone. In case the commentator is really excited with the match, his basic speech tone automatically intensifies with every important action of the game. Analysis of commentator’s intensified basic speech tone was realized in this work too. Also the national hymns of teams playing against each other are a significant moment of the match. That is why detection of a hymn became another subject of analysis. Advantages of MFCC were used to obtain audio signal feature, from which 20 coefficients were gained. These were used as an entrance for classifier based on neural network with back propagation. For easy usage of these methods a graphic user interface with possibility of well-arranged look on gained results and also with possibility of replaying chosen section was created.
