Energy assessment of building of municipality
Janíková, Hana ; Maurerová, Lenka (referee) ; Hirš, Jiří (advisor)
The main objective of the master’s thesis is elaboration of energy audit within the theme of energy rating of buildings. Work consists of the beginning to the given theme including the actual legislative regulations. Another part is elaboration of the energy audit of building municipality with design and rating the measures of reduction of energy consumptions. In experimental part work deals with evaluation of building thermal envelope with use of thermograph measurement, also with quality of indoor environment within the use of building by measurement of concentration of CO2 and with heat and humidity balance.

Contactless measurement of surface temperatures during turning
Merenda, Jiří ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
The goal of this thesis is the incorporation of the contactless measurement of surface temperature among other methods of temperature measurement. Technical preparation for experimental measuring on the machine-tool. Comparison of influence of cutting conditions on the development of surface temperature of workpiece during the machining process with usage of the camera ThermaCAM CS2000. The economical analysis of the contactless measurement of surface temperature is determined in the last part of this thesis.

Utilization of infrared camera for temperature measurement of electrical machines
Líbal, Jan ; Aubrecht, Vladimír (referee) ; Kuchyňková, Hana (advisor)
The master‘s thesis deals with utilization of infrared camera for temperature measurement of electrical machines. The first part describes non-contact temperature measuring, the second part describes principle of sensors that evaluate quantity of incident infrared radiation. In the next part there is termovision camera SAT-HY 6800 presented and the instructional manual for SAT Report computer programme created. This computer programme is used for analyzing of termovision pictures from the SAT-HY 6800 termovison camera. The chapter 7 describes temperature measuring of one-phase asynchronous motor type J22TO484. The chapter 8 describes temperature measuring of semiconductor components of EC motor G6 series. Both of these motors are produced by ATAS elektromotory Náchod a.s. The last part of the thesis describes creation of animation of one-phase asynchronous motor type J22TO455. The animation was created in 3ds Max computer programme.

Proposal of measures for reducing energy demands of food stores
Julinová, Patricie ; Vlach, František (referee) ; Bečkovský, David (advisor)
The master thesis deals with measures to reduce energy performance of grocery store building. Model of the grocery store is evaluated according to a recommended energy values specified by Czech standards and according to the real values of the actual consumption. These values are compared. Final building analysis for a proposal measures to reduce energy consumption is based on the invoices of the real consumption and on the experimental assignments. Experimental measurements are the Blower door test of the tightness of the building envelope, the measures with the thermovision camera and the measuring of the illumination intensity. The most efficient proposal is extended to the whole model network of the food shops in the Czech Republic.

Measurement of surface temperatures in mechanical engineering
Stránský, Marek ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
This work deals with contact and non-contact methods of surface temperature measurement. The work contains a list and formulations of basic terms and laws of thermodynamics. Furthermore, the work deals with the description and comparison of the properties and use of certain devices for contact and non-contact surface temperature measurement. The experimental part is focused on dependence of the turning speed on the turning knife thermal stress. Subsurface thermocouples, surface thermocouples and thermovision were used for the temperature detection. The subsurface temperatures were afterwards used (as data inputs) for the inverse calculation of surface temperatures. All results obtained were then compared to each other.

Contactless thermography in clinic medicine
Langerová, Jana ; Staffa, Erik (referee) ; Bernard, Vladan (advisor)
This thesis deals with the theory of infrared thermography in medicine and its subsequent practical application in the creation of the program. As part of this diploma thesis, researches were carried out on the topic of thermovision imaging techniques, its use mainly in clinical medicine and also research in the field of image data processing. Theoretical knowledge is written into the first three chapters of this thesis. The next chapter deals with the design of a web application for the analysis of thermographic images of patients with vascular disease lower limbs and the PHP program environment with its particulars. In the second half of the thesis there is a detailed description of the practical creation of the mentioned application in PHP environment with the use of some PHP libraries. One chapter is also devoted to the discussion of the method of obtaining thermographic images for testing the created application and to the statistical evaluation of acquired data. This thesis is divided into 8 different chapters and also into many sub-chapters.

Contactless measurement of surface temperatures in mechanical engineering
Gorčica, Jakub ; Forejt, Miloslav (referee) ; Polzer, Aleš (advisor)
This diploma thesis is focused on the theory of contactless measurement of surface temperatures with thermovision camera Flir SC2000 and on the principles of imaging the camera is based on. The tablets and the applications making work with camera easier are processed in the Visual Basic in practical part. The stand for fine taking emissivity is compiled and described, and emissivity of different materials and different milling cutters is taken in this diploma thesis.

Prevence škod působených zemědělskou technikou na zvěři
Palacký, Jan
The subject of the work is the prevention of damage caused by agricultural machinery to game. Attention in the solution was focused on agricultural machinery and mechanization used in pre-sowing soil preparation. Based on the identification of conflicts between small game and the used agricultural mechanization, related significant environmental aspects were identified. The thesis deals with the levels of biodiversity, environmental agricultural mechanization, which is conflicting from the point of view of wildlife. Individual species of small game that are injured or killed during these works are also identified. Based on the identified environmental aspects, related legal requirements were set. The result of the work is the determination of suitable methods for the prevention of these damages. As part of the design of technology, a suitable perspective method was selected for verification - measures to prevent and minimize damage to game. The method of monitoring with observational thermovision was chosen for the research, thanks to which it was possible to search for endangered young hares in selected localities together with the nesting grounds of the Lapwing with the aim of expelling them or marking them enabling subsequent fixation. Based on the performed monitoring, it was found that the use of manual thermal imaging can be used for active protection of small game.
