Visible blindness in the urban world society's relation to light now and then
Pata, Václav ; Sedlák, Michal (advisor) ; Gajdošíková, Pavla (referee)
The diploma thesis is focused on city in time and age of artificial lighting. It takes the issue of light pollution as its starting point. Elementary sources and consequences of over- lighting are used as a base for the Forgotten Dark worksheets. The sheets were created in collaboration with Veřejný sál Hraničár (Public Hall Hraničář) as an educational material for the gallery cycle Light. Together with the sheets, a need to widen my knowledge and apply it to a specific situation arose. I picked Obchodní dům Prior and Kulturní středisko Corso (Shopping Mall Prior and Culture Center Corso) in the neighborhood of Krásné Březno for that purpose. The pick of the place directed the development of the themes of the theoretical part of the thesis. The middle part of the thesis is trying to show contemporary city from two essential angles. Firstly, I tried to answer the question about sources of the shape contemporary city has taken upon itself. The rest is focused on building public spaces in regard to their nighttime flow. The final chapter is exploring the object of Corso. At first It is trying to take a look at the context of the city part of Krásné Březno, then it is taking a look at the city part in context of Ústí nad Labem. The gathered information is used for a presentation of possible future of...

Scene Analysis Based on the 2D Images
Hejtmánek, Martin ; Drahanský, Martin (referee) ; Orság, Filip (advisor)
This thesis deals with an object surface analysis in a simple scene represented by two-dimensional raster image. It summarizes the most common methods used within this branch of information technology and explains both their advantages and drawbacks. It introduces the design of an surface profile analysis algorithm based on the lighting analysis using knowledge and experiences from previous work. It contains a detailed description of the implemented algorithm and discusses the experimental results. It also brings up options for the possible enhancement of the projected algorithm.

Microdots scanner
Červinka, Luděk ; Honec, Peter (referee) ; Horák, Karel (advisor)
The microdots are very small object. The microdots are applied in protection object. The project purpose is to find and to analyze the microdots. The project consists from two parts. A first part describes the hardware sensor construction and a second part describes the software solution. I selected the optics, camera module and illumination in the hardware part. I’m analyzing of the microdots on a picture in software part.

Design of a lifting mechanism for artificial lighting for hydroponic cultivation
Černoch, Lukáš-David ; Máša, Vítězslav (referee) ; Naď, Martin (advisor)
The work deals with the optimization of lighting for hydroponic systems in terms of energy efficiency, using a lifting mechanism. It is based on the selection of a suitable lighting, stroke solutions and the possibility of simple automation. The introductory part analyzes the basic principles and variants of hydroponic farms, their advantages, disadvantages and description of partial parts. The work is focused on the design of the light lifter mechanism, so it describes in more detail the different types of lighting for growing plants, and also summarizes the various lifting mechanisms from which it is chosen the most suitable. Subsequently, a 3D model of the selected mechanism was created including a motion study. The final part of the practical part was the price return calculation of the mentioned mechanism.

Electronic instrument for environment monitoring during plants growing
Žák, Jaromír ; Kuchta, Radek (referee) ; Hubálek, Jaromír (advisor)
The main goal of this project is to make electronic instrument for monitoring environment during plants growing for Mendel University of Agriculture and Forestry in Brno. The new device will replace current analog recorder of temperature and humidity. New device will be extended by measuring atmospheric pressure, illumination and CO2 concentration. Main advantage of electronic measuring is better lucidity of gained values. New concept allows easier comparison new values with earlier measured data.

Brightness control of light sources
Dostál, Lukáš ; Vorel, Pavel (referee) ; Huták, Petr (advisor)
Thesis is focus on brightness control of lighting sources. The first objective of the thesis is to determine basic concepts and explain interrealationships among particular magnitudes of lifting technology. Further is necessary describe functionality, particular light sources and thein possibility of use in practise. There is also outline issue of darkfall of particular types of sources and their evolution. The other part of thesis compare energy output of lighting sources and describe their possible future development. Further this thesis deals with options of regulating of brightness for LED moduls. There is also proposal of acceptable amperage regulator LED moduls including its software - microcontrol ATMEL AVG. Microcontrol ATMEL AVG Tiny 13 is programme in C language within computer environment AVR Studio 4 and will be record through the use of AVR Dragon.

Advanced laser diagnostic systems to measure flow field
Loutocký, Petr ; Lízal, František (referee) ; Jedelský, Jan (advisor)
The aim of this work is to give readers a comprehensive view of the present laser methods for measuring the velocity of fluid flow. The methods are classified and compared according to various criteria. Individual techniques are briefly outlined their principles of measurement, options and range of applications. Furthermore, this work discusses the advantages and disadvantages, appropriate areas of application and the basic parameters. At the end we can find a sample analysis of data measured by one method.

The Lighting of Liturgic Space
Jedličková, Veronika ; Přikryl, Miroslav (referee) ; Zdařil, Zdeněk (advisor)
The bachelor thesis deals with the lighting of aisles, chapel and space under the chior in St. John the Baptist’s church in Frýdek-Místek. The thesis has two parts. The first part focuses on whole concept of lighting, also location of lighting fixtures and its impact on the overall space effect. The second part is the design of the luminaire, respecting the specifics of the space. The luminaire is also trying to satisfy the lighting requirements established by the local parish council.

Light chromaticity sensor
Rejthar, Martin ; Boušek, Jaroslav (referee) ; Šteffan, Pavel (advisor)
Thesis is aimed on problematics and analysis of colorimetry, as an instrument of exploration of light and its characteristics. Research is made to find plausible methods of measurement and comparing light. First part is focused on theory, to discuss basic physical principles connected to lighting and colorimetry. Possible applications of these theoretical knowledge during the realization of the portable meter are studied. Next part speaks on construction and requirements on such a device and processing of results. Device is later assembled, and the basic measurements are performed.
