Accounting and Inspecting IP Telephony Traffic
Sivák, Vladimír ; Ryšavý, Ondřej (referee) ; Matoušek, Petr (advisor)
This thesis describes architecture of IP telephony networks based on signaling protocol SIP and transport protocol RTP. Also tools used for analyzing VoIP traffic are described. Main objective is to design and implement a system for the detection of calls and extraction of voice payloads from the captured packets. The system first recognizes the signaling messages of SIP protocol. These messages are analyzed afterwards. Output statistics are generated based on gathered data. Voice data will be stored in form, which is suitable for further processing.

Home Multimedia Centre
Burkert, Michal ; Herout, Adam (referee) ; Sumec, Stanislav (advisor)
This thesis deals with design and implementation application, that should be equivalent to several eletronic devices such as DVD player or videotape recorder. Computer used for this purpose is often branded as Home Theater Personal Computer (HTPC). This thesis studies available multimedia libraries and software in operating system Linux, that is used to create designed application. It shows some similar existing application to create HTPC either commercial or opensource.

A Control System for Applications Testing in Linux
Beneš, Eduard ; Vojnar, Tomáš (referee) ; Smrčka, Aleš (advisor)
This thesis discusses the area of a control system for application testing in Linux. There is a need for testing software and its quality using automated software tools. Huge number of testing tools is available, Red Hat Test System (RHTS) being one of them. Dierent approaches to classi cation and evaluation of a testing tools are presented. Selected software testing tools were evaluated and compared with RHTS. The thesis then presents a design of a system for non-interactive application testing in Linux with support for RHTS tests and with focus on future enhancements. Implemented system is nally tested using proposed set of tests and several usage examples are described.

Methods of Document Summarization on the Web
Belica, Michal ; Očenášek, Pavel (referee) ; Bartík, Vladimír (advisor)
The work deals with automatic summarization of documents in HTML format. As a language of web documents, Czech language has been chosen. The project is focused on algorithms of text summarization. The work also includes document preprocessing for summarization and conversion of text into representation suitable for summarization algorithms. General text mining is also briefly discussed but the project is mainly focused on the automatic document summarization. Two simple summarization algorithms are introduced. Then, the main attention is paid to an advanced algorithm that uses latent semantic analysis. Result of the work is a design and implementation of summarization module for Python language. Final part of the work contains evaluation of summaries generated by implemented summarization methods and their subjective comparison of the author.

Advanced Simulator of MSP430 Microcontrollers
Kaluža, Jan ; Bidlo, Michal (referee) ; Vašíček, Zdeněk (advisor)
The goal of this master's thesis is to provide an introduction to MSP430 microcontrollers and to design a simulator of these microcontrollers, focusing on easy implementation of extensions using peripherals. After a short introduction, the MSP430 microcontrollers are briefly described, including their internal peripherals and the formats used to store the binary executable code. The thesis continues with a description of discrete event simulation using the DEVS formalism. Based on previous chapters, the new simulator (consisting of a simulation core, graphical user interface and library for MSP430 microcontroller simulation) is designed and implemented. The implementation is tested by comparison with real microcontroller and in the end of the thesis, there is a summary and evaluation of the implemented simulator.

Support for Jenkins Plugin Development in Python Language
Bambas, Tomáš ; Letko, Zdeněk (referee) ; Müller, Petr (advisor)
Jenkins CI, the continuous integration server, enables to extend its functionality by plug-ins. These plug-ins can be written in Java and Ruby. The support for Python language is missing although it is one of the most popular programming languages. Therefore we have implemented the SDK for Python plug-in development and this SDK has been integrated into the Jenkins CI community repository. The documentation for the plug-in development in Python has been also published. Thanks to that work, developers can now implement plug-ins in Python programming language.

Automated Web Page Categorization Tool
Lat, Radek ; Bartík, Vladimír (referee) ; Malčík, Dominik (advisor)
Tato diplomová práce popisuje návrh a implementaci nástroje pro automatickou kategorizaci webových stránek. Cílem nástroje je aby byl schopen se z ukázkových webových stránek naučit, jak každá kategorie vypadá. Poté by měl nástroj zvládnout přiřadit naučené kategorie k dříve nespatřeným webovým stránkám. Nástroj by měl podporovat více kategorií a jazyků. Pro vývoj nástroje byly použity pokročilé techniky strojového učení, detekce jazyků a dolování dat. Nástroj je založen na open source knihovnách a je napsán v jazyce Python 3.3.

A Compiler of Language Python Subset
Falhar, Radek ; Křivka, Zbyněk (referee) ; Kolář, Dušan (advisor)
Python is dynamically typed interpreted programming language. Thanks to its dynamic type system, it is difficult to compile it into statically typed source code. The kind of source code, where it is exactly specified what types exist and what their structure is. Multiple approaches exist how to achieve this and one of the primary ones is type inference. This approach is attempting to infer the type structure from the source code. In case of Python language, this approach is difficult, because resulting type system is quite complex and language itself is not designed for type inference. In this work, I have focused on identifying subset of this language, so that type inference is possible while keeping the natural way the language is used. Then I implemented a compiler, which will compile this subset into statically typed language, which can be translated into native code.

Universal Graphic Editor Library and Python Module
Košulič, Jaroslav ; Kočí, Radek (referee) ; Smrčka, Aleš (advisor)
The diagrams, schemes, and graphs in general are widely used in the field of easy-to-read information visualisation. We use them for example in the school lessons for an algorithm presentation, or in the technical jobs such as software and hardware development by modelling UML diagrams, database schemes, etc. The project Universal Graph Editor has been established two years ago to fill the gap with the software tool providing such a modelling engine. The previous work has been reasumed in semestral project by design of the dynamic graph drawing (or the drawing of a vector graphic in general) and the library for graph manipulation with C-language interface. This master thesis continues further by creating a Python module using the developed interface. The documentation and the testing phase is conluding the annual work.

System Log Analysis
Ščotka, Jan ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
The goal of this master thesis is to make possible to perform system log analysis in more general way than well-known host-based instrusion detection systems (HIDS). The way how to achieve this goal is via proposed user-friendly regular expressions. This thesis deals with making regular expressions possible to use in the field of log analysis, and mainly by users unfamiliar with formal aspects of computer science.
