Parallel Lexical Analyzer
Ježek, Lukáš ; Koutný, Jiří (referee) ; Čermák, Martin (advisor)
This bachelor thesis deals with generating a lexical analyzer which analyzes a file in parallel, i.e. by several threads at a time. The analyzer is generated on the basis of regular language and is represented by finite automaton with the necessary functions. The emphasis is placed on the parallel processing. The possibility of forward and back threads processing is discussed in this thesis. The method of the forward threads was decided to be used for implementation. The problems during implementation that lead to almost none of the desired speed-up of the analysis are discussed.

IPv6 Network Prefix Translation
Ježek, Lukáš ; Polčák, Libor (referee) ; Grégr, Matěj (advisor)
This master thesis deals with testing network prefix translation algorithm in IPv6. It tests existing implementation. This implementations are compared with each other. Some implementations end with error compilation. There are two options how to deal with this problem, it might be repaired or the port to the new kernel is created. Performance is tested with Spirent hardware packet generator.

Solution techniques for the frequency assignment problem
Ježek, Lukáš ; Nejedlý, Pavel (advisor) ; Lidický, Bernard (referee)
Wireless communication is used in a growing number of situations, for example in mobile telephony, wireless networks (WLAN), television and radio broadcasting, satellite communication or in military operations. It is necessary to solve the frequency assignment problem in each of the above situations, so that the communicating sides get connected and their connection is not interfered by other communicating subjects and connections. It is very important to be able to solve the problem well since the number of the participants in the wireless communication is rapidly growing. This work provides introduction to the frequency assignment problem along with the overview of the most frequently used techniques for solving it. Selected methods are described in more details and are also implemented in the enclosed program.

C-language code generator for SOFA 2
Ježek, Lukáš ; Bureš, Tomáš (advisor) ; Bulej, Lubomír (referee)
SOFA 2 is a component system employing hierarchically composed components. It provides ADL-based design, behavior specification using behavior protocols, dynamic reconfiguration of the components, and modeling of the component communication by software connectors. This allows seamless and transparent distribution of component applications. The connectors can be automatically generated, SOFA 2 contains Java connector generator allowing to connect components with Java interfaces. The aim of this thesis is to implement C code generator and integrate it into the current SOFA 2 connector generator framework, so that C connectors can be automatically generated and thus components written in C language can be transparently connected in distributed environment. The proposed C code generator is based on the concept of template transformation, where templates containing mixture of C code and a scripting Domain Specific Language are transformed to a pure C code. Strategic term rewriting method provided by Stratego/XT framework is used for evaluation of the scripts within the templates.

Generation of computer program for specific-heat analysis
Majer, Peter ; Ježek, Lukáš (referee) ; Javorský, Pavel (advisor)
This work is about to design and implement the speci c-heat analysis application. The application consists of two parts: the rst one provides for data manipulation, the second one plots a graph. The data manipulation part resembles a spreadsheet program - each column in a dataset stands for one measurement. Columns containing a temperature data could be used for a speci c-heat calculation. This calculation is based on this model functions: conduction electrons consideration, phonon contribution and Schottky contribution. It is also possible to arrange your own formulas by using basic mathematical operations (namely summation, substraction, multiplication and division). Fitting data to the selected model is also possible. Levenberg-Marquardt and simplex method are being used for it. Hamiltonian matrix used for energy levels calculations of magnetic ions in crystalline electric elds could also be calculated. The application is written in C# programming language.

Project management in software developing company and its support
Ježek, Lukáš ; Svoboda, Jiří (advisor) ; Novák, Jan (referee)
This case study tries to describe posibilities and also concrete case of project management implementation in a internet development company. In the first part of this study there are different views on project management in the form of Word known methodologies. Simultaneously he is trying to evaluate default state of internet company before aplying of project management into internal processes of the company. On the base of default state analysis author is therefore targeting on the most complicated areas of all today's companies in project management. There are: Change management, ressource management, risk management, financials and utilizing of human resources. In these areas there is a author's view on the theme. Is there any chance to apply any project management metodology into so turbulent environment as the internet companies are.
