Modelling of Cell Colony Dynamics
Bělehrádek, Stanislav ; Škutková, Helena (referee) ; Sedlář, Karel (advisor)
The content of the thesis is a description of intracellular processes responsible for cell cycle regulation and reactions of cells to external and internal stimuli. Thoroughly described are important signaling pathways with appropriate methods, which can be used to simulate them in silico. From these cellular processes, a cell cycle model is created and implemented in a tool programmed in C ++ with OpenGL used for visualization. The model is then tested for various cell processes including HeLa cells growth. Finally, the results are compared with the behavior of living cells.

Tato práce se zabývá použitím zobecněných Laguerrových funkcí pro modelování a identifikaci dynamických systémů. Po krátkém úvodu je uvedena definice zobecněných Laguerrových polynomů a funkcí a některé jejich vlastnosti. Je zavedena metoda pro identifikaci spojitých dynamických systémů z diskrétních nasamplovaných dat s použitím zobecněných Laguerrových funkcí a porovnána s metodou nejmenších čtverců. Je diskutována volba optimálních parametrů p a alpha pro konečné Fourierovy řady se zobecněnými Laguerrovými funkcemi. Na příkladech je porovnána navržená identifikační metoda s metodou nejmenších čtverců. Je zavedena diskrétní Laguerrova transformace a její rozšíření s použitím zobecněných Laguerrových funkcí. Na příkladech je předvedena aplikace diskrétní Laguerrovy transformace na kompresi dat. Je ukázáno, že použití diskrétní Laguerrovy transformace může vést k lepším výsledků při kompresi dat než tradiční postup s využitím diskrétní kosinové transformace.

Models of public transport in the GIS environment
Loukotka, Tomáš ; Grill, Stanislav (advisor) ; Brůha, Lukáš (referee)
Models of Public Mass Transportation in GIS Environment Abstract The thesis tries to describe and categorize models of public mass transportation. A new model is built upon these models and based on authors' thoughts. This model is constructed to work with headways only instead of timetables. Therefore one cannot precisely estimate the passengers' behaviour. The model works also with street network aside from public transportation lines. An application is built upon these model and allows network editing and processing of shortest-path analysis and accessibility analysis. Technologies used: ExtJS, OpenLayers, CGI, Shapely, STORM, PostgreSQL. This application is then used for building a public transportation network of Prague 6 region and for performing analysis upon this network.

Procedurální generování měst
Beneš, Jan ; Wilkie, Alexander (advisor) ; Křivánek, Jaroslav (referee)
This thesis proposes a novel method for procedural generation of urban street networks. A simple traffic simulation, based on observations made about the social-geographic nature of cities, that is able to drive the temporal evolution of city road networks by creating new major roads, as well as a modified generation algorithm for minor roads, are described. The presented method is highly automated.

Numerical model of NATM tunnel in stiff clays
Svoboda, Tomáš ; Mašín, David (advisor) ; Hilar, Matouš (referee) ; Barták, Jiří (referee)
Disertační práce představuje aplikaci hypoplastického konstitučního modelu při realizaci NRTM tunelu v prostředí městské zástavby s cílem obdržet "class A" predikce chování zeminového masivu. Tunely Královo Pole tvoří hlavní konstrukci severní části Velkého městského okruhu v Brně. Tunely o šířce 14 m a výšce 12 m jsou raženy v prostředí tuhých brněnských jílů s výškou nadloží v rozmezí 6 až 21 metrů. Materiálové parametry hypoplastického modelu kalibrované na výsledky laboratorních experimentů byly optimalizovány využitím dat geotechnického monitoringu a následně použity při simulacích tunelu. Po průchodu ražby profilu tunelu zvoleným úsekem staničení došlo k vyhodnocení prediktivních schopností a vhodnosti konstitučního modelu. Druhým konstitučním modelem použitým při simulacích průzkumné štoly a plain strain analýze tunelu je Mohr - Coulombův model. Metoda redukce napětí využitá v procesu optimalizace parametrů byla vyhodnocena formou porovnání s 3D simulacemi. K vyhodnocení posloužily simulace třech skutečných podzemních konstrukcí s nízkým nadložím realizovaných v prostředí tuhých jílů. Abstract The thesis demonstrates the application of a hypoplastic model in class A predictions of a NATM tunnel in an urban environment. The Kralovo Pole tunnel is a main construction of a northern part of a...

Beneš, Martin ; Zápotocký, Martin (advisor) ; Hejnová, Lucie (referee)
The purpose of this thesis is summing up the information about olfactory transduction of vertebrates. This review is divided into four parts, each part focuses on a different aspect of olfactory transduction. First there is an overview of basic electrophysiological methods used for transduction research, followed by a description of a complete transduction on a molecular level. Next is a summary of model types and their use in olfactory transduction simulation, including a detailed description of two models: One of them describes the beginning of olfactory transduction, from the odorant binding on the receptor to the cAMP production, the other deals with the negative feedback of Ca2+. Finally there is an overview of software products designed to create and analyze the models from the preceding section.
