Physical Simulation of a Cloth
Vavro, Ondrej ; Seeman, Michal (referee) ; Navrátil, Jan (advisor)
Thesis covers problematics of simulating cloth(textile) behaviour under different conditions. It explains basic principles used in construction of cloth computer model, describes inner and outer forces that act on cloth and shows different integration methods that forward simulation in time from the view of suitability and speed when used on cloth simulation. Work also includes description of implementation of a demo application in which is part of these problematics tested.

Simulation of Large Particle Systems
Štambachr, Jakub ; Navrátil, Jan (referee) ; Juránek, Roman (advisor)
This bachelor thesis adresses the problem of large-scale particle system simulations. Its main goal is to create an efficient simulation model of cosmological N-body systems and its consequent testing. I chose to implement a version of Barnes-Hut Tree-Code algorithm, which meets the requirement for a high-speed simulation method. The tests carried out within the scope of this thesis imply that tree-code method is of a logarithmic complexity. As an output of this simulation model I present several videos, demonstrating in an illustrative fashion a functionality of the model.

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.

Differential amplifiers with bipolar transistors
Vyroubal, Petr ; Boušek, Jaroslav (referee) ; Horák, Michal (advisor)
This bachelor thesis deals with the theory of differential amplifiers with bipolar transistors, an overview of the basic connections and inspection their properties with the help of computer simulation program OrCAD PSpice. The specific type of differential amplifier is carried out experimental measurements, which perform as verification of simulated properties. The aim of this work is to analyze and compare the results obtained using the simulation program and the results obtained by laboratory measurements.

Dimensional stability of investment Al castings
Úředníček, Lukáš ; Cileček, Jarmil (referee) ; Horáček, Milan (advisor)
The aim of this paper is to compare a bottom filling of a ceramic form made by lost wax process and a top filling conventional method. A computer simulation of filling and casting solidification will contribute to this comparison. The comparison includes evaluation of readings DAS and characteristic readings of porosity with chosen varieties of casting. The results show that the readings DAS did not change much but characteristic readings of porosity were much better at bottom filling. The computer simulation also showed a certain contribution in the field of model smelting technology.

Analysis of indoor climate of spa resort
Chadima, Tomáš ; Rubinová, Olga (referee) ; Horká, Lucie (advisor)
The thesis deals with the environmental assessment of buildings, concrete objects Letní lázně at Karlova Studánka. The first part describes the issue and legislation. There is also described a method of experimental measurement and methods of moisture measurement. The second part deals with the analysis of the specified object, description of selected renewable sources and description of possible modifications of the object. The third part is devoted to modeling and simulation of the specified object in DesignBuilder. Using the model were created various simulations with various modifications in order to reduce energy intensity of the object. Results were then evaluated and compared.

Motion control logic sequences making body in the topcoat
Křivánek, Filip ; Hloska, Jiří (referee) ; Škopán, Miroslav (advisor)
This thesis describes the finish-painting area at ŠKODA AUTO a.s. company in Mladá Boleslav. The logistic operations and transporter technology in this production hall are described here. Furthermore this thesis is concerned to sequence making of car body before the finish-painting area. The output evaluation is make of experiments and comparison of influence of an old logic of choosing a colored block with a new control logic for car body with influence on the correct shifting of car body according to a sequence number. The containers for car body including all other workplaces of the painting area are created in the Plant Simulation program.

Effect of steric constraint and surface interactions on the behavior of block copolymers (Computer study)
Blovský, Tomáš ; Limpouchová, Zuzana (advisor) ; Lísal, Martin (referee)
In this thesis, the influence of spatial confinement and interactions with solid surfaces on the conformational behavior of symmetric diblock amphiphilic copolymers A5B5 is stud- ied using dissipative particle dynamics (DPD). In the first two chapters, the motivation for studying such systems and the description of the simulation method are given. In the remaining chapters, the effect of spatial confinement on the association behavior of diblock copolymers is studied, as well as the effect of interactions between the solvophobic block B and the solid wall. The results are compared with simulations without spatial confinement. DPD simulations showed that the attractive interaction between block B and the wall significantly changes the association behavior of block copolymers in a se- lective solvent, whereas the purely steric effect is negligible in spatially confined systems with a non-interacting wall. Keywords: block copolymers, surface interactions, steric constraint, computer simula- tion, complex solution, dissipative particle dynamics

Physical aspects of cooling the surface (skin) of animals and the possibility of using computer simulations for their quantitative analysis
HOLÝ, Lukáš
The aim of the bachelor´s thesis was to create a basic version of a computer model, which will enable computer simulations of the cooling of a solid body by a flowing fluid, in our case specifically air. The computer model will then be further developed as part of the diploma thesis with the aim of simulating the cooling of the skin of living animals. The bachelor´s thesis also introduces the reader to the basics of working in the COMSOL Multiphysics program, especially to the individual steps in the preparation of a computer model. Physical aspects and phenomena at the basic level, which are applied during simulation, are also discussed in the thesis.
