Modelling and HIL Simulation of Vehicle Boot Door Control
Musil, Filip ; Matějásko, Michal (referee) ; Brablc, Martin (advisor)
This diploma thesis focuses on an analysis, a model creation and simulations of a car boot door mechanism. The problem was analyzed on the basis of real measurements made on three different vehicles. Based on the measurements, computational models describing the real system at different levels of complexity were created. Matlab/Simulink was used to create and calculate the models. The output of the thesis is the simulator of a car boot door which also includes simplified model of a control unit. The simulator should provide an approximation of current and kinematic quantities of these mechanisms. The model is implemented on dSPACE platform that allows real-time simulations. The simulator can be modified in terms of changing the parameters of the mechanism and modifying some of its results.

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.

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.
