Automation of the cultivation process in term of program control of temperature and moisture
Beneš, Vojtěch ; Papežová, Stanislava (advisor) ; Neděla, René (referee)
Theoretical part of this thesis describes different kinds of sensors used for measuring temperature and humidity of air. These sensors are categorized according to the principle on which they operate. It also describes their characteristics like range, accuracy and other aspects important for determining suitability for a glasshouse automation system.
Practical part of this work covers design of this system which can be used for auto-mated controll over temperature and humidity. It reasons about suitability of different kinds of sensors and materials. It also describes a software system capable of maintaining and changing humidity and temperature based on user input. Results of different mea-surements done during the system's operation in a variable environment are evaluated to draw conclusions about the system's ability to maintain constant temperature and humidi-ty levels inside the glasshouse.

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.

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.

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.

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.

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.
