Multimedia Data Distribution over Internet
Vodák, René ; Szőcs, Juraj (referee) ; Číka, Petr (advisor)
The text of this work deals with multimedia data distribution over Internet with a focus on creating web pages using application APIs that are available on Google and creating an independent video portal using open-source scripts ClipBucket and PHPmotion. There are analyzed problems of transmission of video and audio data using Web browsers. There are described protocols and codecs for video streaming in web browsers. In details it is described creating of Web sites with the inclusion of application API directly into the HTML source code and creating an independent video portal with a complete configuration of the server for hosting. As an annex the created Web pages are listed with video content and laboratory exercises on the practical test and integration of multimedia content and the practical administraton of the video portal.

Techniques for parallel computing
Vodák, René ; Hasmanda, Martin (referee) ; Lattenberg, Ivo (advisor)
The text of this thesis deals with techniques of parallel processing calculations. It is an analysis of the most important libraries for parallelization including libraries for parallelization on GPU graphics cards and computing speed by comparing these libraries in Visual Studio 2010 based on a simple application searching primes on three different computer hardware configurations. With OpenCL library, that achieved the best result, there are formed two applications – an improved program for searching prime numbers using the sieve of Eratosthenes and a program for calculating the integral with the trapezoidal rule.

Mathematical Analysis of Fluids in Large Domains
Poul, Lukáš ; Feireisl, Eduard (advisor) ; Pokorný, Milan (referee) ; Vodák, Rostislav (referee)
This thesis contains a set of articles concerned with flow of a viscous, compressible and heat conducting fluid in large domains. In the first part of the thesis, the existence of the weak solutions in unbounded domains is studied. The results follow each other in the way they were obtained through the time, and range from a simple extension to bounded domains with Lipschitz boundary up to the most general existence theorem for fluid flow in general open sets. The existence results are supplemented with the study of existence of weak solutions in the unbounded domain case with prescribed nonvanishing boundary conditions for density and temperature at infinity. The last contribution then concerns with the low Mach number limit in the compressible fluid flow.

Marketing Activities Support of Innovation
VODÁK, Robin
The diploma thesis titled "Marketing Support for introducing Innovations to the market" was intended to process recommendations for marketing support for introducing innovations to the market for the selected business. The main sub-goal of the work was to determine the prognosis of the future development of innovation - a specially developed vending machine for the preparation of nutritional supplements, including the right choice of types, brands, flavors and prices of individual nutritional supplements. The goal of the work was fulfilled. The evaluation of the results and the subsequent recommendations were based on the results of the questionnaire survey and the results of market testing.

Saturation overshoot as a basis for emergent flow phenomena in unsaturated homogeneous porous media
Fürst, T. ; Vodák, R. ; Šír, Miloslav ; Tesař, Miroslav
Understanding and description of fluid motion in unsaturated porous media rates among the most challenging and still not fully resolved problems. Traditionally, porous media flows were described by the continuum mechanics apparatus [1]. The continuum mechanics based models lead to partial differential equations which are mathematical formulations of the balance of mass, momentum, and energy. The most celebrated model is the so called Richards’ Equation (RE) [2]. Other continuum models (see [3], [4] and the reference and discussion therein) are various extensions built on similar principles as the RE.

New suspect in the investigation into the cause of flash floods
Bíl, M. ; Fürst, T. ; Vodák, R. ; Pražák, Josef ; Šír, Miloslav ; Tesař, Miroslav
The aim of this contribution is to introduce a new possibility of the description of unsaturated porous media flow. The approach presented here is entirely different from the traditional ways (e.g. the Richards‘ Equation). It will be explained why the traditional models often fail to describe various observed phenomena. The new approach provides certain interesting forecasts, among others a possible mechanism for flash-flood formation. The authors explain why they think that, under specific conditions, porous medium discharge may substantially exceed the infiltration due to rainfall.
