Creation of Knowledge Database for Lighting Technology with the Possibility of Expert Query Processing
Krbal, Michal ; Sokanský, Karel (referee) ; Gašparovský, Dionýz (referee) ; Baxant, Petr (advisor)
This presented thesis is focused on the complex description of creation the database system for the lighting. The important static and dynamic parameters of light sources and luminaires are listed in the first part of thesis. These parameters are complemented by the measured values and their relationships. The next chapters of thesis are focused to description of obtained parameters, structural design, historical and expected development of individual representatives of light sources. In the following sections are described current state of used data formats of luminaires and the possibilities for describing of light sources. The database systems are created as a result of this thesis. These databases are used for collecting, sorting, searching and sophisticate comparison of the parameters of light sources and luminaires.

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.

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.

Lighting system reconstruction in the Sokol hall
Kattauer, Jakub ; Štěpánek, Jaroslav (referee) ; Škoda, Jan (advisor)
The thesis is focused on the problems of illumination of interior space, especially in object in Moravský Písek. The thesis is divided into two parts, where the first part deals in general with the basic quantities and terms which are used in illumination systems. Further, it is about general properties of lights and about general terms of illumination of interiors. The second part is only practical character. At the beginning, there is used manual measurement and modelling to evaluate initial state in program Relux. The measurement is not met in terms of standards. Thanks to the municipal council of Moravský Písek a new lighting system is created, which fully respects the valid normative regulations. Installation of control system of lighting is integrated to proposal, which would result in lower consumption, greater user comfort and greater versatility in the possible use of the object. In the end, there is financial evaluation of illuminating system and comparison classical with led technology.

Smart Home Control by Utilizing AllJoyn Platform
Resler, Tomáš ; Kováč, Dominik (referee) ; Hošek, Jiří (advisor)
This bachelor work concerns with system Alljoyn which tries to standardize the interface for communication in the frame of intelligent house. The basic principles and the structure of the framework Alljoyn including the recent proposal of the modules Lighting framework and Gateway Agent have been described in the theoretical oriented part of the work. The practical oriented part stars with the description of the getting the Alljoyn framework including the Lighting controller and the Gateway Agent to work on the hardware router provided with operating system OpenWRT. The following parts present own testing connector for the Alljoyn Gateway which have been written to allow the remote control of the lights via cloud service Twitter. The functionality of the router have been tested with software simulator of the Alljoyn lights Luminaire and an own ligths driving program developed utilizing the experimental Lighting SDK for mobile devices with operating system Android.

Volumetric Efects Accelerated on GPU
Kubovčík, Tomáš ; Tóth, Michal (referee) ; Starka, Tomáš (advisor)
This thesis deals with simulation and rendering of fluid based volumetric effects, especially effect of fire and smoke. Computations are accelerated on graphics card using modern graphics API with motivation to achieve realistic visual results as well as physically correct calculations. Implemented volumetric effects are distributed as dynamic library which allows addition of these effects to existing applications.

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.

Visual inspection of axial bearing
Sýkora, Vojtěch ; Richter, Miloslav (referee) ; Janáková, Ilona (advisor)
This thesis is about visual control and measurement of bearings by using image sensors and it is about providing appropriate conditions for this measurement. It describes the selection of suitable hardware to solve this case. A large part of the thesis is the design and creation of my own light. Furthermore, algorithms for processing the acquired images of bearings are proposed. The result of the processing is the determination of the type of bearing in the image and the finding of possible defects.

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.
