Methods of Identification of Vehicle Brake System Temperatures
Jaroň, Dominik ; Fojtášek, Jan (referee) ; Hejtmánek, Petr (advisor)
The work is aimed at measuring temperature of main parts of vehicle braking system. The first part is theoretical background for temperature measuring by thermocouples, IR pyrometers and paint pyrometers. There are also introduced devices and products, which are nowadays available to buy and which can be used for measuring. In the second part of this thesis there are shown methods of measuring by mentioned thermometers and evaluation of their pros and cons.

Control of heating a house
Hnyk, Marek ; Musil, Vladislav (referee) ; Šteffan, Pavel (advisor)
This paper deals with a proposal of a system which will control and regulate the heating and warming of hot water in an old detached house. Although this system is designed for a particular object, to a certain extent it should be variable and capable of adaptation. Current control system 3, 6 or 9kW is too rough, making the overall operating uneconomic. This project should be created with emphasis on economic side of individual components.

Thermal analysis of electric machine
Ječmínek, Tomáš ; Ondrůšek, Čestmír (referee) ; Janda, Marcel (advisor)
This masters thesis is focuse for measuring devices of temperature and their usability and accuraci in the event of asynchronous engine in operation. The values from meusuring of engine are used for preparing optimalization of construction. The right proposal of construction is check in numerical program and the results are validation.

Brake Disc Temperature Measurement on Moving Vehicle
Mužák, Jaroslav ; Rasch, František (referee) ; Blaťák, Ondřej (advisor)
Subject of this diploma work is to complete preliminary report of possibilities and problems with brake disks monitoring on moving vehicle. A vital condition is to choose appropriate temperature sensor as well as assembling complete measuring set and it’s fastening to the vehicle. Temperature readings from driving tests, after specific brake maneuvers, will be evaluate and according to them a sensor will be determined as appropriate or inappropriate for this kind of tests.

Design of system control and diagnostics water heating using solar energy
Kužel, Kristián ; Zuth, Daniel (referee) ; Vdoleček, František (advisor)
This thesis deals with problems related to heating of hot service water. It focuses on solar water heating, describes individual types of solar panels and summarizes the existing information about solar water heating. It demonstrates actual problems of solar system solution on a specific example of a two-generation family house, where it analyses possibilities of diagnostics and control of such system. It also deals with suggestions of possible expansion of the current solar system.

Measurement of thermal field in electric machines
Dostálek, Martin ; Vítek, Ondřej (referee) ; Janda, Marcel (advisor)
Diagnosis temperature is one of the most important disciplines. We meet it in everyday life, but it is very important for all sectors of industry. This is a measurement providing an immediate state of the measured object. Contact measurement of different temperature sensors and contactless measurement using thermal imagers. The important part is the measurement of temperature rise of induction motor. Part of the work deals with losses in the electric motor. These losses are converted into heat, which affects from various parts of the machine. Correct identification of the temperature field is important in helping to design the cooling system of the instrument. Virtually the data obtained are compared with theoretical data. We will capture part of the device and realize thermal simulations in a suitable simulation program. We propose modifying the cooling machine and the resulting data from the simulation compares.

Longitudinal index structures in optical fibers
Polreich, Štěpán ; Čučka, Milan (referee) ; Urban, František (advisor)
This thesis describes basic concepts, principles and properties of optical fibers. Considerable part is devoted to fiber gratings that are created by a change in the refractive index in the optical fiber core. In this work is described description, principle, method od production and distribution of gratings on Bragg gratings, gratings with long period and chirped gratings. In this thesis are also presented different types of lasers and their advantages over other lasers. A large part deals with the description of the femtosecond laser, with which the structures will be later made into the material. In addition, the laser modes are differentiated, this is a mode of micro-machining and modification or a change in refractive index of the material. The last part deals with change the refractive index in planar technology, the creation of a groove for fastening the fiber and attempts to write the gratings into the optical fiber. Created fiber sensor are tested for temperature and tensile changes. Finally, the practical use of sensors made by femtosecond laser and the advantages over UV laser and phase mask techniques are presented.
