Hydrodynamická spojka / Fluid couplingVavrla, Zdenek January 2013 (has links)
This diploma´s thesis deals in the first part with hydrodynamic coupling, mainly on her construction and function description. In the second part of this diploma´s thesis is solved influence construction changes of the hydrodynamic coupling to the transmitted torque. Changes in the construction are determined by changing the number of blades and changing the value gap between the turbine and pump round. Finally, construction change is solved of the hydrodynamic coupling to increase the transmitted torque and force effects are evaluated on the hydrodynamic coupling.

Analýza obtokového kanálu turbodmychadla / Analysis of turbocharger waste gateOndrejka, Adam January 2015 (has links)
The aim of master’s thesis was to put forward calculation methodology of wastegate turbocharger bypass channel discharge coefficient. Designed methodology was based on discharge coefficient analysis conducted utilizing CFD simulations of turbocharger turbine-side parametric model. It was achieved to propose a calculation, which differentiates relatively in average 1,4% from CFD data. New methodology improves the accuracy bypass channel design and helps to choose appropriate wastegate valve actuator.

Pokročilý simulátor mikrokontrolérů rodiny MSP430 / Advanced Simulator of MSP430 MicrocontrollersKaluža, Jan January 2014 (has links)
The goal of this master's thesis is to provide an introduction to MSP430 microcontrollers and to design a simulator of these microcontrollers, focusing on easy implementation of extensions using peripherals. After a short introduction, the MSP430 microcontrollers are briefly described, including their internal peripherals and the formats used to store the binary executable code. The thesis continues with a description of discrete event simulation using the DEVS formalism. Based on previous chapters, the new simulator (consisting of a simulation core, graphical user interface and library for MSP430 microcontroller simulation) is designed and implemented. The implementation is tested by comparison with real microcontroller and in the end of the thesis, there is a summary and evaluation of the implemented simulator.

Interaktivní simulace chování tkaniny akcelerovaná pomocí GPU / Interactive Cloth Simulation Accelerated by GPUMelichar, Vojtěch January 2016 (has links)
This master thesis deals with interactive cloth simulation accelerated by GPU. In the first part there is a description of all technologies used during implementation of a program. The second part discusses various simulation methods. It is mainly focused on particle systems as a most used method. These parts are followed by a design of the program, which is implemented as a part of this thesis. The program was implemented in four variants. The first variant is CPU implementation, which was then optimalized with OpenMP. CUDA implementation is based on these implementations. Last variant implemented in this thesis is optimized CUDA implementation. All these implementations are evaluated from compute complexity point of view and suitability for real time graphics.

Modelování protokolů pro management na úrovni L2 / Modelling of L2 Management ProtocolsRajca, Tomáš January 2016 (has links)
This thesis deals with modelling and simulation of management protocols on the data-link layer in OMNeT++ tool. Namely protocol CDP, LLDP and ODR routing. These protocols are described in the first thesis' half and in the second half is described their design and implementation in ANSA project. Correctness of implementation is verified by comparison between simulated and real network examples. Also dependencies on module DeviceConfiguratoru were removed from ANSAINET library.

Spontánní asociace polyelektrolytů ve vodných roztocích (disipativní částicová dynamika) / Self assembly of polyelectrolytes in aqueous solution (dissipave particle dynamics)Šindelka, Karel January 2014 (has links)
Title: Self-assembly of polyelectrolytes in aqueous solutions (dissipative particle dynamics) Author: Karel Šindelka Department: Faculty of science, Charles University in Prague Supervisor: Doc. Ing. Zuzana Limpouchová, CSc. Consultant: Doc. Ing. Martin Lísal, DSc. Abstract In the thesis, the coarse-grained dissipative particle dynamics (DPD) is used for the study of self-assembly of equimolar mixtures of oppositely charged symmetric block PEs with one PE block (either strong polycation or strong polyanion) and one readily water-soluble neutral block in aqueous media. In the first part of the diploma thesis, the principles of DPD simulations are described and the correct implementation of electrostatic interactions in the DPD method is demonstrated on the example of counterion (Manning) condensation. In the second main part, the effect of the blocks solubility, incompatibility and the interplay of different forces on electrostatic assembly is investigated. The cor- responding neutral systems are also simulated for comparison. The study shows that the hydrophobicity of the PE backbone and the incompatibility of blocks sig- nificantly affects the electrsotatic co-assembly. The presence of opposite charges on different chains promotes the aggregation process and the aggregation number in- creases in comparison...
