Rendering Surface Detail with Advanced Mapping Techniques
Stehlík, Lukáš ; Pelikán, Josef (referee) ; Ambrož, David (advisor)
The thesis deals with algorithms of computer graphics which exploit advanced techniques of textures mapping with the aim of improving the projection of details of wrinkled surfaces. The evolution and architecture of modern graphic cards are described. There is the description of basic characteristics of the Cg language for graphical accelerators too. Algorithms for simulation of wrinkled surfaces such as normal (bump) mapping and parallax mapping are described in detail including the explanation of basic terms and principles. Extra focus is laid on the method named displacement mapping and its application on modern graphical cards. The thesis describes possible improvements of the above mentioned methods with a view to problem of implementation of displacement mapping method. Part of the work is a program that visualizes methods including improvements. There is a discussion on results obtained from testing the program on different graphical cards. All the methods and their improvements are compared with respect to both the projection quality and the speed of processing.

Programmable Shaders in OpenGL
Radil, Přemek ; Havel, Jiří (referee) ; Švub, Miroslav (advisor)
OpenGL is mostly used in video games, computer aided designs, virtual reality, flight simulations or scientific visualisations. This bachelors thesis puts mind to production of shaders written in OpenGL Shading Language and their attachment to OpenGL aplications. Its objective is to describe methods of creating depth of field, glow and soft shadows effects and to provide tutorial about these methods. First chapters informs about OpenGL and associated library OpenGL Utility Toolkit and illustrates some common procedures necessary to achieve hereinbefore mentioned effects. Last chapters dwells directly on shaders creating these effects.

Energy and water management in a residential building
Auer, Zbyněk ; Vendlová, Lucie (referee) ; Šikula, Ondřej (advisor)
The bachelor thesis deals with the management of energy and water in a residential building. For the energy balance of the residential building were used computational tools NKN II and outputs simulation on software BSim2000. On the basis of the calculations were prepared Et-curve for the residential building, which was subsequently supplemented by real measurement.

Modelling of Projects with Stochastic Cyclical Structure
Sládková, Ivana ; Zouhar, Jan (advisor) ; Kuncová, Martina (referee)
The Presented Thesis is focused on exploitation of stochastic cyclical networks in project management during project planning. Particularly, it is focused on the GERT method, which enables to carry out both the probability analysis and the time analysis of projects with stochastic structure. We deal primarily with analysis of such networks where cyclical activities occur. As an integral part of the Thesis, derivation of simplified computing procedures for cyclical activities is included. We extend the possibilities of the GERT method with stochastic evaluation of time duration of activities using the fuzzy GERT method. This fuzzy GERT method is applied on the real project and its results are compared to results of Monte Carlo simulation.

Computer naratology: narrative templates in computer games
Praks, Vítězslav ; Hrbata, Zdeněk (advisor) ; Češka, Jakub (referee) ; Kubíček, Tomáš (referee)
Relations and actions between literature and computer games were examined. Study contains theoretical analysis of game as an aesthetic artefact. To play a game means to leave practical world for sake of a fictional world. Artistic communication has more similarities with game communication than with normal, practical communication. Game study can help us understand basic concepts of art communication (game rules - poetic rules, game world - fiction, function in game - meaning in art). Computer games are interpreted in the study using naratological and ludological approach. Computer is tracted as a narrative medium (to narrate means to demonstrate, to present any content, not only epic content). Computer games are interesting phoenomena for its specifical aspects: interactivity, self-narration and computer simulated narration. Main attention in this study is focused on phoenomena of computer generated literature (prose and poetry). The main purpose of this area is in study considered for literary analysis of "belles lettres". Author examines and demonstrates plausible computer generated fiction analysis of narrative texts. Two such analysis are proposed in a study, one of them (prose analysis - fabule generation) is detaily manifested on concrete literary text.

Visualization in vector spaces
Klímek, Jakub ; Hladík, Milan (referee) ; Fiala, Jiří (advisor)
The goal was to create a set of Java applets, which would serve as an addition to the teaching of Linear algebra. These applets make possible to compute with rational numbers, real numbers, complex numbers and Zp - integers modulo prime p using addition, subtraction, multiplication and division. It is also possible to compute with vectors of elements of those spaces using addition and subtraction of vectors and multiplication and division by scalar. In addition, the vector calculator can figure coordinates of a vector, determine a linearly independent subset of vectors and, when in standard scalar product space, figure an orthogonal projection onto a subspace generated by a set of vectors. The advantage of these applets is their ease of use simulating a classical handheld calculator.

Application of the Three-Body Problem in the form of exercises
Kolář, Karel ; Šolc, Martin (advisor) ; Franc, Tomáš (referee)
The main topic of this work is the Restricted Three-Body Problem (R3BP) which is illustrated by solving several examples and by simulations in computational system Wolfram Mathematica. The aim is to offer supplemetary material for university students and it can be used also as introduction to this topic for high school students. The first part is dedidated to history of celestial mechanics and to the people who contributed to the development of the R3B Problem. The second chapter consists of simplier tasks with definitions of basic quantities and variables and revision of the undisturbed two-body problem. Subsequent chapters are concentrated to Lagrange points, Jacobi integral, Hill surfaces, tidal force, Tisserand criterion, shape and evolution of close binary stars and other partial tasks.

Accelerated Neural Networks on GPU
Tomko, Martin ; Zachariášová, Marcela (referee) ; Krčma, Martin (advisor)
This thesis deals with the implementation of an application for artificial neural networks simulation and acceleration using a graphics processing unit. The computation and training of feedforward neural networks using the Backpropagation algorithm are the main focus of this thesis, but the application also supports other network types, and it makes it possible to extend the application with different training algorithms. Next, the application allows us to create neural networks with structural anomalies, and thus, to test the neural network's fault tolerance. The application is implemented in the C++ language, using OpenCL to manage GPU computation. The Backpropagation acceleration results were compared with the free open source library FANN.
