TV Remote Controller
Bordács, Balázs ; Hála, Ondřej (referee) ; Hermany, Jiří (advisor)
This master’s thesis deals with parameters of the TV Remote Controller. Aim of this work is studying standards of remote controling of TV receiver by the way of infra-red light. For succesful solving of this project is important to learn about the theory of IrDA. In the second part ot this thesis is designed measurement unit for measuring the parameters of the remote control. The measurement unit includes an integrated IR receiver and photodiode for receive IR signals from remote control. The description of measurement unit blocks and principles of measuring parameters are also placed there. The final part is devoted to processing the measurement results of measuring levels and time waveforms of signal in the receiver module, directional characteristics of remote control and receiver. For measuremented unit is created laboratory task including the role specification and protocol.

Possibilities of increasing the durability of concrete products based technologies hardening their surface
Minaříková, Kateřina ; Eger, Lukáš (referee) ; Hubáček, Adam (advisor)
In the last years, we focus on higher quality of surfaces in the field of vibro-pressed concrete products. Therefore, there are products with specially modified backing layer in the market where there is implemented impregnation coating on the surface that is cured by ultraviolet and infrared radiation. The primary objective of my thesis is summary of the existing knowledge about vibro-pressed concrete products that are modified by these technologies. I will especially focus on description and efficiency of using particular methods, principals of curing surfaces and other modification of concrete product’s surfaces with emphasis on its durability. There will be examined in the laboratory conditions some of the characteristics of these vibro-pressed concrete products as resistance of surfaces against water effects and chemical defrosting substances, water absorption of surfaces, abrasion resistance, slip resistance, as well as risk reduction of creating lime efflorescence on the concrete surfaces.

Analysis of infrared acquisition parameters
Zembol, Filip ; Drastich, Aleš (referee) ; Čech, Petr (advisor)
The topic of my thesis is the analysis of parameters of the infrared imaging and the usage of these parameters for the design of a thermographic equation and a programme in the MATLAB environment in which the termography formula and the influence of the particular quantities, which take part in it, will be graphically depicted. In the thesis we will first of all introduce the infrared radiation, its types and features. With the help of the particular radiation laws and distracting elements of the infrared radiaton a formula trimming the distracting elements of the thermal relief will be designed. This formula will enable us to count the emission surface temperature of the scanned scene (grey body) and thus eliminate the elements influencing the resulting temperatures of the scanned scene. Furthermore, a programme which will image the IR acquisition model (thermogram) on the basis of the thermography equation will be designed. The thermogram will change in dependence on the changes of the thermography equation quantities. The change will be expressed by the shift of the color spectrum (thermographic scale). This programme graphically presents the changes of the quantities influencing the resulting scene and provides a better grasp of the influence and the function of particular quantities in the thermographic equation.

Assessing the impact of the closing of paint and lacquer surfaces on the durability of concrete products
Zubkova, Ekaterina ; Eger, Lukáš (referee) ; Hubáček, Adam (advisor)
This diploma thesis is focused on studying the influence of different types of surface treatments on vibropressed product. The main goal is to characterize surface treatments consisting of application of surface coatings that are hardened by infrared or ultraviolet radiation. Theoretical part gives specifications already known methods for surface finishing. Briefly describes selected types of prefabricated concrete parts and specificate the requirements for these products. It also describes used test methods. The experimental part was aimed at establishing the effectiveness of changing properties concrete products by adding coatings on their surface. This was achieved by testing the properties of concrete paving blocks with modified surfaces and testing of reference blocks that did not have any surface treatment followed by mutual comparison of the results.

Study efficiency of modern thermal insulation for buildings
Šot, Petr ; auditor, Karel Trojan, Brno, energetický (referee) ; Šťastník, Stanislav (advisor)
The bachelor´s thesis deals with the problem of thermoreflect insulation. The small part of thesis focuses on the energy demand of buildings and its problems. Then the greater extent is analysed problems by heat transfer of material. It includes effects arising from the individual methods of heat transfer and defines the level of expression of individual methods of heat transfer in materials. The thesis presents an overview of experimental methods for determining thermal insulating properties of insulators. Then there is shown a selection of the most widespread insulation materials used in today´s construction. It includes the division of insulators in terms of used materials and subsequent classification of the most used materials in these groups. Another part of thesis deals with the thermoreflect isolation. There are mentioned the necessary concepts for the study of thermoreflect thermal insulation, which include the emissivity surface, the coefficient of mutual radiation and translucency of the material. Then there is described the method heat transfer of thermoreflect isolation. On the next there are presented experimental methods of determining thermal insulating properties thermoreflect thermal-insulating material. The thesis also includes a practical part, which contains the measurement results on a small range of samples taken termoreflection insulators. In the end there is mentioned a brief realization of thermoreflection thermal insulation materials in buildings.
