Iterative solution of singular systems with applications
Blaheta, Radim ; Jakl, Ondřej ; Starý, Jiří ; Turan, E.
This contribution concerns the iterative solution of singular systems which arise in many applications. Let us mention the following: - solution of PDE problems with pure Neumann boundary conditions (which is our main aim), see [7], [8], [20]. Such problems have a specific role in numerical upscaling, see [6], - solution of Neumann type subproblems in domain decomposition techniques as FETI, Neumann-Neumann, BDDC methods, see [22], [16], - analysis of Markov chain problems, computation of stochastic vector, see e.g. [18], [19], - computer tomography [15], [14] and inverse problems [4], [21].

Bridge - computing optimal strategies
Cejnar, Pavel
We give a theoretical model of the game Bridge and its simplified variation. We construct an algorithm for the best response against any given strategy in this model. Then we construct an algorithm for an optimal strategy of the players based on the Brown-Robinson iterative method and we extend this method. In the appendix we also describe algorithms based on heuristic principles that are used in commercial programs.

Semi-adaptive Dictionary compression methods
Urban, Tomáš ; Lánský, Jan (advisor) ; Dvořák, Tomáš (referee)
Goal of this work was to design and test methods for creating and parsing input data from file or stream in a way they are optimalized for following compression algorithms. We used two runs through data, first run collected analytical data and second run was for parsing. First part of this document is focused on methods TD2 and TD3 [4] for trie compression and their extension for unicode alphabets. In second part there are presented methods for creating dictionary without considering partitiong on words or syllabels. All methods are considered over unicode alphabet and implemetned as part of modular program XBW.

Testing of raster to vector graphics conversion software products
Mináriková, Monika ; Šedivá, Zuzana (advisor) ; Kunstová, Renáta (referee)
This work is mainly focused on testing of software for conversion between raster and vector graphics. It is divided into two parts. In methodological part there are stated the ways of storing image data in the computer. It explains the differences among basic types of computer graphics, raster and vector, and characterizes their well-known formats. Practical part deals with testing and comparing selected SW supporting the process of tracing. Based on the results, general conclusions about the possibilities, which offer this way of automatic vectorization, are determined. For evaluating and comparing the SW multi-criteria evaluation based on a five-point scale is chosen. The parameters of the evaluation are then divided into two categories: the evaluation of the SW and the outputs from the tracing process. Four types of graphics are chosen for the tracing: a simple black-and-white logo, a full-color logo, a line drawing, and a photograph with a simple motif. The conclusion of the thesis summarizes and evaluates all the results.

Computer Games nad Simulation (oriented on MMOG)
Šach, Martin ; Rosický, Antonín (advisor) ; Brixí, Radim (referee)
The goal of this Thesis is not only a plain description of common characteristics of Massive Multiplayer Online Games (their sorting and conditions on where they run are included), but also their integration to the wider phenomenon -- to cyberspace. Cyberspace reference is present in all recommendations and game specifics. Cyberspace is it`s base ingredient, the authority, to which all those parts are revoking to. And here it comes our second and main goal. The need of integration of players to that virtual world. To seek her desires, her true nature. That maybe done by describing various game devices and methods of connecting users of those devices to the cyberspace, let alone by expanding reader`s horizons to places, not known to her. All that is lead by one effort -- that the person, who will read that Thesis carefully, will be able to answer the question, if players get exactly what they need. And she`ll be able to do that before reading to the end.

Mobile hardware solution for audio work
Liška, Jakub ; Šubrta, Václav (advisor) ; Brixí, Radim (referee)
The objective of this thesis is to finding a solution for mobile computer audio recording and editing. We are searching for appropriate solutions based on defined needs. For calculations we have used the multi-criteria selection method. To be exact, we are searching for computers and external sound cards. The result is the location of the computer and the sound card. It is a hardware set, which can be used for amateur or semi-professional audio work. The thesis describes more possible solutions and shows the advantages and disadvantages of them.

Computer Network Design for the Multifunctional House
Gruberová, Nelly ; Melega, Tomáš (referee) ; Ondrák, Viktor (advisor)
The objective of this work is to analyze and design a computer netwrok for multifunctional house, where is located an unnamed company and also a family of four members. The content of the first part is an analysis of the current situation, which is inconvenient. The second part deals with the theoretical bases, which is used in the third part, where is custom design solutions. The specific procedures and elements are contained in the last part.

The design and implementation of an innovated school computer network.
Kolbe, Stanislav ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
Tato bakalářská práce se zabývá návrhem a realizací infrastruktury v menší školní síti. Cílem práce je jednak zanalyzovat současný stav pevné sítě, identifikovat zdroje problémů a odstranit je. Dalším cílem práce je navrhnout a postavit bezdrátovou síť. Tato práce se skládá z několika částí. Na úvod nastíním postupy používané při návrhu sítě. V další části budou teoreticky vysvětleny některé aspekty pevné sítě. V třetí části bude popsáno navržené řešení problému pevné sítě. Ctvrtá část se zabývá bezdrátovými technologiemi a nakonec bude popsáno řešení výstavby bezdrátové sítě

Network Repository for Performance Evaluation Results
Ondroušek, Pavel ; Kalibera, Tomáš (referee) ; Tůma, Petr (advisor)
For performance evaluation of software systems, benchmarking is used. Benchmarking generates a large amount of output data, which is necessary to store, process and evaluate it. Network Repository serves as a repository of benchmark results. The goal of the master thesis is to design and implement the data storage with a support of various result types with the possibility of the format configuration. Stored results can be processed, evaluated, or used as a source for plotting. As part of the master thesis, the design and implementation of a general framework for benchmark storage and evaluation is developed and a sample configuration for the selected benchmark result data format is established.
