The systems of building services in immovable heritage
Maurerová, Lenka ; Vlček, Milan (referee) ; Kabele,, Karel (referee) ; Doc.Ing. Martina Peřinková, Ph.D (referee) ; Hirš, Jiří (advisor)
The present PhD. thesis deals with the systems of building services (namely heating, ventilating and air conditioning, shading) which provide required indoor microclimate inside the immovable heritage. The work thus combines the exclusively technical field of building services (BS) and the general principles of heritage conservation. The aim of my PhD. thesis is the analysis of immovable heritage conservation processes, focusing on the current state of research and BS systems documentation. Furthermore the work concerns the possibilities of temporary measurements of indoor climate parameters inside the immovable heritage, and aims to develop a computer model (in BSim software) for the simulation of various working conditions in the selected buildings. For the stated aims were selected three representative historic houses: historical assembly hall at the Faculty of Civil Engineering, Brno University of Technology; the Palm Greenhouse at Lednice Chateau in Moravia; and Villa Tugendhat in Brno. These buildings had been surveyed for several years, and in this PhD. thesis I present their analysis, evaluation, and conclusions. The aims of this PhD. thesis broadly correspond to the transnational objectives. The present research is, for example, in accordance with the international document ICOMOS Charter (Zimbabwe, 2013) which is concerned with the analysis, conservation, and restoration of architectural heritage. The research of immovable heritage is also supported by European Union, e.g. by the Seventh Framework Programme of EU.

Fluid Dynamics Simulation Using Cellular Automata
Režňák, Michal ; Janoušek, Vladimír (referee) ; Peringer, Petr (advisor)
The main objective of this work was to create application for fluid flow simulation using Lattice Gas Cellular Automata. Used simulation models are HPP, FHP-I, FHP-II and FHP-III. The program is implemented in a C++ language in a way that it can run in WebAssembly web standard. Part of the work is comparison between wasm, ams.js formats and native desktop (x86_64). This shows that time for application loading in web browser is much smaller for wasm format than for asm.js and application performance in wasm format is about 24% higher than asm.js but 50% smaller than a native desktop. The application is suitable for educational purpose as a presentation of cellular automata simulation and also as an introduction to the Lattice Boltzmann method for fluid flow simulation.

Numerical simulation of compressible flows using the parallel computing
Šíp, Viktor ; Dolejší, Vít (advisor) ; Felcman, Jiří (referee)
In the present work we implemented parallel version of a computational fluid dynamics code. This code is based on Discontinuous Galerkin Method (DGM), which is due to its favourable properties suitable for parallelization. In the work we describe the Navier-Stokes equations and their discretization using DGM. We explain the advantages of usage of the DGM and formulate the serial algorithm. Next we focus on the parallel implementation of the algorithm and several particular issues connected to the parallelization. We present the numerical experiments showing the efficiency of the parallel code in the last chapter.
