Graphics Scene Visualization Using OGRE Library
Ondrejíček, Marián ; Navrátil, Jan (referee) ; Pečiva, Jan (advisor)
The goal of this thesis is to investigate the possibilities of the OGRE visualization library and to implement an application which utilizes both simple and advanced OGRE features. Furhtermore there are explained basics of creating effects using Cg language and connecting them with OGRE library. The Bullet library which is often used in visualization applications for physics calculations is analyzed as well. The second part describes implementation of the demo application. In the end, the results are discussed, including possibilities of future development.

Manufacture of centrifugal castings from iron and non-ferrous alloys
Virgl, Vítězslav ; Kaňa, Václav (referee) ; Cupák, Petr (advisor)
The goal is to give a comprehensive explanation of centrifugal casting technology. It describes the process and its parameters, the forces acting on the molten metal, the basic principles and methods. There are also mentioned the types of forms used. Emphasis is placed on the cast materials. Furthermore, there are covered all benefits and drawbacks of centrifugal method and shown some larger Czech foundries with their current production capabilities.

Safety Management System for Transport of Materials and Dangerous Substances
Klímová, Zdeňka ; Krejčí, Libor (referee) ; Adamec, Vladimír (advisor)
The task this master’s thesis was evaluated present status safety management system for transport of materials and dangerous substances. I looks this issues like whole in The theoretical part. I want to find all kritical locations. I analysis type of transport, transport routs, driver training, legislation and label the most transport of materials and dangerous substances. I want to found the risk to remove or cushion. I want to proposed preventive measures in the practical part.

POF - polymer optical fibres
Mikulec, Matěj ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
This work focuses on polymer optical fiber (POF). It describes basic properties of polymer optical fibers, materials for production and methods of manufacturing processes. In following chapters are given individual fibers that vary different refractive indexes and diameter of fiber. Also there are analyse connectors which are used for joining. As very suitable solution for home installation seems to be using the system Optolock without connectors. In the work is also written several areas where it is possible to use the POF. It can break through in automotive industry, home networks or as a sensor. The practical part contains measuring polygon draft and FTTH proposal using POF for distribution system in the house, where P2P topology is choosen. It´s also made a proposal for distribution of POF in the apartment. For installation in the apartment prices of network components are compared between POF distribution and UTP cat.6 cabling. UTP cat.6 is in this comparison many times more cheaply. Final chapter evaluate demands on work with POF fibers. Describes preparation of fiber before communication and creation of small experimental network. Important findings of the work are summarized in the conclusion.

Audio speaker system with baffle made from alternative materials
Hüttl, Ondřej ; Schimmel, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This thesis firstly consists of an analysis and a description of materials suitable for construction of loudspeaker enclosures and a design of the loudspeaker system with the enclosure made of a synthetic stone. Electro – acoustics drivers have been described with a focus to a frequency range, a principle and a construction for an explanation of their function. Drivers based on electrodynamic principle have been described closely. An analysis of materials used for the loudspeaker enclosure production has been done and tradicional and alternative materials have been described as well. Specific modulus, density and stiffness have been taken as an objective evaluative criterion. An evaluation indicates appropriate properties of plastic, aluminum and stone based materials. The function and kinds of loudspeaker enclosures have been described. The function, properties and design of a vented box loudspeaker system have been described closely. The last part of this thesis is individual design of a two-way vented box loudspeaker system with the enclosure made of synthetic stone. A simulation of a driver behavior built in the enclosure and compensation circuits and crossovers design and simulation have been done. The enclosure has been designed with high stress to minimize negative effect of the enclosure to the final sound quality.

Piston Rings of Modern Diesel Engines
Homola, Petr ; Knotek, Jiří (referee) ; Raffai, Peter (advisor)
This bachelor thesis concentrates on piston rings and is divided into several points. First point deals with the functions of piston rings and with the demands for them, in the second point there is a division according to the type of the ring and constructing solution. Another chapter deals with materials that are used the most when fabricating piston rings and the last chapter deals with the surfacing that is used the most.

Piston Rings of Modern Petrol Engines
Cupák, Václav ; Maršálek, Ondřej (referee) ; Raffai, Peter (advisor)
This bachelor thesis deals with issues of piston rings used in modern petrol engines. The first part is focused on describing of functions and requirements with which piston rings must deal with. Next part is aimed on shapes of piston rings. Materials from which are piston rings made of are part of third chapter. For proper function, it is important to make some surface treatment. The last chapter contains surface treatment of piston rings.

Pressure vessels pressurized water reactors
Horváth, Radovan ; Martinec, Jiří (referee) ; Suk, Ladislav (advisor)
The aim of this bachelor thesis is the development of research on the topic of the pressure vessels of pressurized water reactors. Next is to outline the various design solutions of pressure vessels of pressurized water reactor. The thesis is divided into five chapters, contains 1 chart and 7 graphics. The theoretical part is dedicated to the history of nuclear energy and the development itself in the world. The description of the classifications of nuclear reactors is also included in the theoretical part. Summary of the theoretical part consists of a detailed description of the pressure vessel and pressurized water reactor itself. Practical part of this thesis contains the design of 3D assembly model and its modification in the program Catia V5. The overall model is composed of a main assembly, namely the body of the reactor and sub-assemblies, which were gradually installed.
