CFD simulation of refrigerant flow inside the semihermetic compressor
Tuhovčák, Ján ; Knotek, Stanislav (referee) ; Katolický, Jaroslav (advisor)
The CFD simulation of cooling piston compressor Stream, manufactured by Emerson company, is the topic of this diploma thesis. Analysis of moving parts (piston, valves) and refrigerant or physical settings for simulation were based on experimental data provided by Emerson. The goal of the thesis is to test opportunities of Star-CCM+ in simulating the flow inside the compressor. In the end there will be a comparison of experimental data and results from the simulation. The thesis also contains a theoretical background of piston compressors and phenomenon following the operating compressor.

Machinery frame for rewinding electric cable
Palík, Milan ; Kašpárek, Jaroslav (referee) ; Kašpárek, Jaroslav (advisor)
The topic of this thesis is a frame of rewind device of the electric cabels. The main aim is the analysis of the load conditions of the frame and defining figures for those conditions. The method of final elements will be used to check the firmness of the frame followed by the analysis of the particular results. Drawing documentation of the frame set and other parts according to the instructions of head of this thesis are also components of this thesis.

Process performance improvement
Večeřa, Michal ; Musil, Martin (referee) ; Fiala, Alois (advisor)
This diploma thesis deals with preparation of quality management system for certification according to the standard ISO/TS 16949:2009. In the theoretical part of the thesis a various concepts of quality management system are described as well as certification process of ISO/TS 16949:2009. The last theoretical chapter is dedicated to the auditing of quality management system. The practical part is focused to the analyse of the current quality management system as well as performing of internal audits of quality management system. The last chapter is focused on evaluation of effectiveness of internal audits and realization of the first phase of certification audit according to the ISO/TS 16949:2009.

The design of sand mixer with output range 3-5 TPH
Haluza, Lukáš ; Pavlík, Jan (referee) ; Bradáč, František (advisor)
The subject of this diploma thesis is engineering design of the continuous mixer with output range 3-5 TPH. Mixer is instrumental to mixing sand mixture intended to non-permanent sand forms in foundry. Proposed construction has to fulfill the specified functional requirements and parameters. Parts of solution are also necessary analytical and FEA calculations.

Analysis of potential active damping for vehicles
Svoboda, Jakub ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
Diploma thesis deals with the issue of active and semi-active damping and its possible applications in the context of vehicles. The beginning of the document is focused on the actual state, major applications and patents in the field. As each of the individual ways of usage is relatively specific, the next part is aimed particularly at the damping unit of bicycle. Given the choice, real measurements and simulations were made in order to verify the applicability of such a device in practice.

Analysis of data transfer security issues at particular OSI model layers
Kňazovický, Pavel ; Růčka, Lukáš (referee) ; Sobotka, Jiří (advisor)
The aim of this Bachelor's thesis is the analysis of secured data transfer protocols. The very first part is dedicated to the short description of the reference model ISO/OSI. The second one is focused to the secured protocols at particular layers of ISO/OSI model, of which SSL/TLS protocol is closely analysed in the third part. The last part is about often used attacks in the area of computer networks and their services and the basic protection against them is also mentioned.

Operation measurement optimization
Barták, Pavel ; Doňarová, Jana (referee) ; Fiala, Alois (advisor)
This diploma work is aimed to measuring process, by measuring laboratory, during serial productions in international company Bosch Diesel s.r.o. Jihlava producer of common rail. Target of this diploma work is cross-check of evaluated dimensions, reengineering of incomming parts flow from production to measuring laboratory, measuring process, evaluation of results and pass results back to production. This will speedup all process and minimalist risk of production not O.K. products because of latest results from measuring laboratory. Is done analysis of present situation and base on it proposed different variants of solutions for reengineering of measuring laboratory.

Functional Hazard Assessment (FHA) of 4-seat aircraft
Jakl, Jan ; Weisman, Andrej (referee) ; Hlinka, Jiří (advisor)
At the beginning this master's thesis includes of a comprehensive review of aircraft accidents in this category, 2-6-digit aircraft for passenger transport. Since this work focused on autopilot, so naturally there is a basic overview of most common autopilots, which can be found in these aircraft now, but in the future. Functional hazard analysis (FHA) for the 4-seater plane for passenger services primarily investigates cases of catastrophic malfunction, which in most cases accompanied by the likelihood taken from different databases. The airplane, which is created for this analysis will preferably equipped with instruments for IFR flights. There is also a brief overview of the regulations necessary for the installation of these systems in the airplane. At the end of this work is to design the dashboard, a design layout of equipment for future aircraft, with an emphasis on maximum transparency.
