Simulation of nesting of birds
Tóth, Peter ; Knap, Tomáš (referee) ; Brom, Cyril (advisor)
Theory (Storch and Frynta, 1999) suggest that in a process of the evolution some species acquire ability to select better habitats upon presence of habitat features which correlate with expected tness. As far as we know this theory was not yet tested with computational agent-based model. In this thesis we introduce computational agent-based model describing life cycle of autonomous agents in their habitat for studying evolution of habitat selection according to the theory. Results of the simulation show ability of the agents to adopt on differenct habitats by acquision of proper cognitive clues and formation of separate groups of agents within species.

Digital Reconstructed Radiography
Chovanec, Andrej ; Krajíček, Václav (referee) ; Pelikán, Josef (advisor)
X-ray examination is an important part of the medical treatment. Despite all the advantages it introduces, it brings some limitations as well. In the present work we describe a technique that from the acquired CT data reconstructs a digital x-ray image and removes some drawbacks of traditional x-ray screening. Among the most significant improvements over the classical radiography belong generation of the screen from very arbitrary angle and interactive rotation of the image in real-time. In order to obtain the most realistic final image, we put the emphasis on the accurate simulation of physical properties of the x-ray radiation. We also try to get as low computational time needed to gain one image as possible. For this purpose we present a parallelization model that decomposes the required work of some components into several processors' cores and thus noticeably decreases the running time of the algorithm.

Výpočtové a experimentální modelování ventilátoru synchronního generátoru
Ondrůšek, Č.
The paper is concerned with computational simulation of air flow in the individual parts of a synchronous machine. Software FLUENT 6 was used for computational modeling. CFD model of machine fan was built, which was used for calculation of ventilation characteristics. Ventilation characteristics were calculated for three ventilator diameters. The aim was to find operating point for each fan. The results of computer simulation are compared with the measurement, which was accomplished on the synchronous generator using pitot tube and digital micro manometer.

Songs in the English Education.
Moravcová, Tereza ; Tichá, Alena (referee) ; Volavá, Iva (advisor)
The diploma thesis called A Selection and Use of Songs in English Language Teaching discusses the idea of a positive impact of music on language acquisition and tries to stimulate the English teachers to think about the interconnetion of these two areas. In the first part, a current situation of using music in ESL teaching in the Czech republic and abroad is described. The second part focuses on the most important aspects of psychological, language and musical development of a child. A musical view on English phonetics and phonology completes the theoretical background of the thesis. The third part suggests activities and materials suitable for use in ESL classes including lesson plans that may inspire English teachers without musical education to use music and songs in their classes. A separate supplement of this thesis, a CD, provides materials processed in context with ideas of this work.

Strategy of the care of gifted and talented pupils in Slovakia
Sandanusová, Anna ; Švecová, Milada (advisor) ; Čížková, Věra (referee) ; Dytrtová, Radmila (referee)
The disertation thesis has focused on the strategy of care of gifted nad talented pupils in Slovakia. Based on the analysis of present situation we have monitored schools for gifted pupils, basic school classes for such children and these children in Slovakia and mainly in the Nitra region.žiakov. We have been looking for the different types of care of gifted children amongst teachers and students of basic and secondary school in Slovakia. The study has compared different types of care for talented students and pupils provided by different educational institutions (State Vocational Education Institute, National Institute for Education, Slovak Youth Institute ), non- state organizations and foundations. Based on empiric research we formulated a proposal of the strategy of care of gifted and talented pupils, mainly during out-of-school activities (by example of Secondary school specialised activity)

C++ Object Persistency Using Object/Relational Databases
Čermák, Petr ; Skopal, Tomáš (referee) ; Kopecký, Michal (advisor)
This thesis deals with design and implementation of a library providing object-relational mapping services for programs written in C++. Emphasis is put on its transparency and ease of its use. To achieve these goals the library uses GCCXML, a XML output extension to GCC. GCCXML helps the library to get description of the class model used in the user application and to simulate the reflection. For the mapping purposes, new object-relational database features are discussed and a new mapping type is proposed. Implementation of the library is based on three related projects - the POLiTe, POLiTe 2 and IOPC libraries. The proposed and implemented library unifies them into one solid, flexible and extensible platform. Thanks to its modular architecture, the resulting library can be used in several configurations providing subsets of implemented services - database access, reflection and object-relational mapping.

Simulation of Car Traffic
Gregor, Ivan ; Hladík, Milan (referee) ; Pudlák, Petr (advisor)
This bachelor's thesis describes the main components of the program that simulates the car traffic. It describes the representation of road system, agents, simulation in progress and its output. It also describes several results reached during the simulation of concrete traffic situations. Moreover, the comparison between this program and multiagent systems is included in the end of this thesis. The road system consists of roads and crossroads which are controlled by traffic lights. The user of this program can observe different agent's behaviour. The only condition is that the class that represents an agent implements a uniform interface. The term agent means the car and its driver together. It is autonomous object that moves inside the road system respecting given limits of the simulation. Consequently, behaviour of agents is limited by the simulation rules. Agents are possibly controlled by simulation in order to avoid collisions and not to break traffic rules. The output of the simulation is used to compare the successfulness of individual strategies of agents in terms of length of the drive or fuel usage.

AudioCam
Hrinčár, Peter ; Horáček, Jan (advisor) ; Libič, Peter (referee)
The thesis deals with the problem of creating music through movement. Our aim is to implement software that allows the user to control a virtual musical instrument using a webcam. We focus primarily on universal interface controlled by movement. Using the differential motion analysis method and optical flow we obtain the information about a movement. Based on this information the virtual instrument creates tones using MIDI technology. Specifically, we simulate a virtual keyboard on which the user can play. We designed the virtual instrument in such a way that it could be easily extended in the future with other approaches to the process of creating music.

Note on the use of Camassa-Holm equations for simulation of incompressible fluid turbulence
Caggio, Matteo ; Bodnár, Tomáš
The aim of this short communication is to briefly introduce the Camassa-Holm equations as a working model for simulation of incompressible fluid turbulence. In particular we discuss its application for turbulent boundary layer flows. This model (and related models) is studied for several years in mathematical community, starting from Leray [23]. It can be understood as a generalization of some classical fluid models (Navier-Stokes equations, Prandtl boundary layer equations), showing some interesting mathematical properties in the analysis of the behavior of it's solution (e.g. Layton and Lewandowski [22]). It has been found however, that the model predictions can lead to surprising extensions of the use of the model in technical applications, namely in simulating the turbulent fluid flows. This brief paper should be understood as an introductory note to this novel class of models for applied scientists.
