Immediate diagnostics of aircraft jet engines
Valuch, Tomáš ; Molčan, Anton (referee) ; Šplíchal, Miroslav (advisor)
In this diploma thesis is elaborated design of diagnostic system for small jet engines. The aim is to describe the types of possible failures of jet engines, to determine important parameters characterizing the immediate state of engine and define methods for measurement of selected parameters. The first part is devoted to a description of selected types of small turbojet engines, followed by a summary of the most widely used diagnostic methods for assessing the health condition of the engine during operation. The next chapter contains calculation of the engine thermal cycle with characteristics of construction components. Then there is analysis of small jet engine failures with a description of their causes and possibilities of identification by diagnostic system. Thesis continues with a description of measurement methods and selection of the required sensors. Next chapter is focused on the proposed diagnostic system for condition monitoring of the engine. The last part is devoted to an excursion in laboratory for jet engine testing at the Technical University in Košice.

Analysis of dynamic effects acting on the turnout constructions
Hajniš, Jan ; Vukušič, Ivan (referee) ; Smutný, Jaroslav (advisor)
Author´s name: Jan Hajniš School: Technical University - VUT, Brno Faculty of Civil Engineering Veveří 331/95, 602 00 Brno Program: Construction and Transportation Engineering Title: Analysis of dynamic effects acting on the turnout constructions Consultant: Prof. Ing. Jaroslav Smutný, Ph.D. Number of pages: about 70 + attachments Number of attachments: about 40 Year: 2012 This work describes the size and the process of dynamic effect – vibrations and shift – cockles in crossing panel and switch panels of the turnout constructions on steel and concrete sleepers in time and frequency domain. It compares the results of the measurement between these turnout constructions. Dynamic effects are undesirable physical phenomena for operation each train. It is therefore necessary to eliminate these phenomena as much as possible. The result of this test will by means of software programm and measuring set help to determine precisely the advantages and disadvantages of using both turnout constructions, or even to propose their improvements or dimensions.

Bridge type of track shifter
Holomek, David ; Franek, Lešek (referee) ; Štohl, Radek (advisor)
This Bachelor thesis contains a description of a bridge type track shifter model, with the introduction including an analysis of the whole work. The first task describes the look and layout of individual parts of the track shifter model. There is also a description of the AS-Interface database, as well as a section with representations of the sensors and actuators of the track shifter. The fifth part describes the PLC software configuration, and is followed by a section dealing with the errors found in the AS- Interface database. After a description of the track shifter’s control program, the seventh section underlines the visualization aspect of the track shifter model. The final section includes samples of laboratory tasks.

Application for the HAWK regulator
Kvasnička, Petr ; Štohl, Radek (referee) ; Jirgl, Miroslav (advisor)
This bachelor’s thesis deals with the issue of intelligent buildings management and practical use of the control system HAWK from company Honeywell. The thesis describes the basic problem of intelligent building management, exactly why they created and how it is possible to implement building automation, including a listing of available equipment that can be used in these systems. The thesis also discusses one of the systems that can be used for building control. The control system is called HAWK and thesis describes the programming environment and connectable peripherals. For a given control system is formed in the scrubbing practical demonstration device wind tunnel, which is shown using the work of the control system.

Fuel Injection Analysis
Schnabl, Jan ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
The ignition and injection system in any form are an integral part of each car. The development of these systems goes hand in hand with the development of the automobile and his growing industry. Since the nineteenth century to the present occurred in this sector signifcant progress. This thesis is focused primarily on the description of the two systems and their partiton. The development has been recorded from the oldest systems to the newest systems.

Poka Yoke system for production oversee of CVS
Klabal, Petr ; Havlíková, Marie (referee) ; Štohl, Radek (advisor)
Bachelor’s thesis deals with the Poka Yoke system, which is used to achieve zero defects and limitations of quality control. There are different types of mistakes, of which the most common mistakes are caused by the operator. Using the method Poka Yoke it is possible to propose such measures to eliminate mistakes. In cooperation with IMI International s.r.o. company, a division Norgren CZ and led by Production Engineer Petr Štohl and Product Design Engineer Ondřej Kubernát I focuses on the assembly of CVS low valve. In this assembly I monitor to operator, who can make the different mistakes in the individual steps, which may negatively affect the function of CVS low valve. I evaluate the severity for each mistake and for the most serious of these mistakes I suggest the possibility of checking the work of the operator that would lead to its discovery.

Processing of Biosignals Using PC
Románek, Jakub ; Šebesta, Vladimír (referee) ; Sigmund, Milan (advisor)
The Bachelor thesis deals biosignal processing on the computer. In this work are given basic types of biological signals of their way to capture and access to a computer. There are selected examples of available sensors and their subsequent storage record. The project analyzes the software environment, Mathcad and followed to process external signals. Finally, there is a method of measuring the heart pulse and its changes with periods in the histogram.
