Renewable resources utilisation by execution of the Photovoltaic Power Plant Drásov
Novotný, Tomáš ; Spáčil, Lukáš (referee) ; Kříž, Jiří (advisor)
This master’s thesis discuss the renewable energy source utilisation, to be more precise it describes the Photovoltaic Power Plants. These sources are not only capable of contributing to the regeneration of the environment and to the electricity production, but they are also capable of generating the investor’s economic profit. The individual chapters describe the external factors affecting the project, present condition of the project’s realization, the theory of photovoltaic cells and systems, CCTV camera systems, which are necessary for the power plant security.

Optical character recognition from image data
Marinič, Michal ; Uher, Václav (referee) ; Burget, Radim (advisor)
The thesis is concerned with optical character recognition from image data with different methods used for character classification. In the first theoretical part it focuses on explanation of all important parts of system for optical character recognition. The latter practical part of the thesis describes an example of image segmentation, the implementation of artificial neural networks for image recognition and create simple training set of data for the evaluation of the network. It also describes the process of training Tesseract tool and its implementation in a simple application EasyTessOCR for character recognition.

Interactive teaching aids for 3D computer graphics
Balusek, Radim ; Průša, Zdeněk (referee) ; Rajmic, Pavel (advisor)
This diploma thesis deals with the creation of interactive tools for 3D computer graphics. The introduction of the thesis focuses on general theory of curves and surfaces and its mathematical description. The topics of Geometric transformation, Perspective projection and Parametric description of 3-dimensional surface are analysed in more detail. The successive chapter deals with the subject of visualisation of spatial objects in Java platform interface. The practical part describes the implementation of individual applets. JAVA programming language, which uses the library functions JOGL, was employed for the very realization of the interactive tools. The goal of the diploma thesis is the creation of a set of interactive applets in the field of computer graphics. These applets will be placed on the website of the faculty and they will serve students of VUT in Brno to improve the quality of education.

Proposal of wireless sensor network for indoor monitoring of people and objects
Záděra, Zdeněk ; Mráz, Ľubomír (referee) ; Morávek, Patrik (advisor)
This thesis describes the design of wireless sensor network (WSN) for monitoring of people and objects in a building. The work deals with issues of localization and tracking in sensor networks and algorithm implementation to sensor nodes. It also contains a description of the aplication requirements. These requirements form the basis for the proposal. The hardware part of the network consists of sensor nodes IRIS from Crossbow company. The work describes the properties of these nodes. Next part deals with of propagation model and design of the localization algorithm. The paper also describes the communication in the network. The thesis also includes a practical realization of the proposed network, the localization system and its testing. In the work is included a CD with the building schematic in AutoCAD and with source code of created applications.

Automatic system of the central air circulation
Nedoma, Pravoslav ; Pavlík, Michal (referee) ; Havlíček, Tomáš (advisor)
Project is target on design and realisation of device for control of central ventilation and air distribution. Control unit evaluates air quality in habitable rooms and assure automatic air change. System is driven by microprocessors and uses electronically controlled valves and ventilator regulation. Project is focused on evaluation of carbon dioxide concentration and detection of fire in rooms. Control unit cooperate and communicate via data bus with already designated control unit of hot water heating. Whole unit can be easing connected to the PC using ethernet.

An Intelligent camera system
Gogol, František ; Macho, Tomáš (referee) ; Valach, Soběslav (advisor)
An intelligent camera includes a processor, which can extract information from images without the need for an external processing unit, and interface devices used to make the results available to other devices. This paper describes the intelligent camera design and implementation into the Field Programmable Gate Array (FPGA). The implemented architecture contains a camera controller, a memory controller, an IIC controller, a VGA controller, and an execution unit. The camera controller communicates with a CMOS chip. The memory controller communicates with a DDR SDRAM memory. The IIC controller is the interface between a PLB bus and an IIC bus. The VGA controller takes data from the memory and transform them into the VGA format (640x480, 60 Hz). The execution unit extracts the image data from the memory. These data are processed by hardware pixel by pixel, which results in a modified image. The camera units has been implemented in the VHDL and Verilog languages.

Insulation influence on heat consumption
Gregor, Jiří ; Bokišová, Lenka (referee) ; Hejčík, Jiří (advisor)
The aim of this bachelor thesis is to analyzethe energy budget of a house before and after heat cladding and to assess whether the heat cladding is perspective, if the invested money returns and to show the main advantages and disadvantages of cladding. Measured values from 1992 to 2012 are used in this thesis. Heat cladding in our house was done at the turn of 2003-2004 and in the same yearsthe old wood windows were replaced with new plastic ones.

Family house environmental-friendly heating
Kocman, Luděk ; Neterda, Zdeněk (referee) ; Němec, Zdeněk (advisor)
The bachelor’s thesis deals with problem of family house environmental-friendly heating. The theoretic part contains an introduction and it describes options of heating with heat pumps, biomass boilers and solar systems. The practical part rates economy of heat pump working in years 2004-2009. It contains proposal of heating solution in 2010.
