Turbocharger Regulating VNT Mechanism Load Simulation
Cetkovský, Martin ; Svída, David (referee) ; Vančura, Jan (advisor)
This diploma thesis deals with turbochargers with a focus on the ways of their regulation. The main subject is to design CFD simulation for a turbocharger with VNT mechanism at specific positions. Simulation is based on the turbocharger Garrett by Honeywell, for which measurement was realized. Finally torques acting on the vanes are evaluated from the simulation. The means of results improvement are considered at the end of the thesis.

Crank mechanism of in-line three-cylinder diesel engine
Cetkovský, Martin ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective bachelor’s thesis, which will be achived is, for scheduled elementary geometric, thermodynamic and operation parameters cylindrical unit of in-line three-cylinder diesel engine, perform calculation of thermodynamic cycle, design elementary dimensions of piston group and for schedule operation modes perform strength check of connecting-rod eye. Consequently rating value compare with value of real true diesel engine. In introduction is explained basic principle of diesel engine and their design concept. The bachelor’s thesis is consisted of description of calculation and supplement, where the calculation is done. The calculation is accomplished in three parts. Thermodynamic cycle is solved in the first part. Forces acting on piston group are solved in the second part and strength calculation and check of connecting-rod eye is solved in the third part. The end is focused on evaluation of calculation and recent solution of diesel engine.

Clustrovací framework
Cetkovský, Martin ; Žemlička, Michal (referee) ; Galamboš, Leo (advisor)
A clustering framework (Egocentric) is presented in this thesis. It was programmed in the Java 1.5 SE language and its time and memory requirements are lower than those of all similar open source projects found by the author. The thesis provides information about the implementation, includes a demonstration of the project's operation, its options, user's guide and a comparison with an existing framework.
