Determination of climatic factor on the degradation of various solar cells types
Peroutka, Tomáš ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
In this work are discussed photovoltaic cells. There are also discussed basic concepts of radiation source for solar cells. Also mentioned the issue of semiconductors and even the history and evolution of the solar cells. A large part deals with possibilities of photovoltaic cells degradation. In one chapter is an attempt to bring some types of photovoltaic cells and a description of the production of these modules.The practical part deals with photovoltaic modules degradation and its evaluation. Following part compares measured values with the values provided by producer of photovoltaic modules.

Degradation of Photovoltaic Modules
Poledník, Tomáš ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
The bachelor diploma thesis is focused on the constructional technology of the solar modules as well as on the problems of the induced degradation under the influence of the potential. It specifies the key issues and possible elements that influence the effect of environment with regard to possible causes of the origin of degeneration. The thesis includes the description of measuring of the polycrystalline and monocrystalline technologies that are resistant to the leading potential. Furthemore, the measuring was carried out on the chosen testing pieces that had been affected by the degradation of the output

Bus wiring systems for complex building management
Mokrý, Lukáš ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
The aim of my thesis is to examine current opportunities of bus wiring systems for complex building management, mainly its power and economic evaluation. It can be simply called intelligent electrical installation. I will examine two systems from INELS and ABB company. These systems contain functional components, mainly modules and controllers. By means of other materials, I’ll create a panel. Components will be placed there and electrically connected. After this, systems will be put into operation and programmed by means of their software. The next step is measuring of quatities during the various conditions of systems and consumption, which is one of the main aims of the thesis. Two apparatuses will be used for measuring. This thesis itself will contain theoretical analysis of systems, their description, using the way of operation and main advantages and disadvantages. Single components and complete process of measuring and working in laboratory will be described. An overall evaluation and comparison of the systems from various points of view, including the price, will be put together from results.

Implementation of Mining Modules of Data Mining System on NetBeans Platform
Stríž, Rostislav ; Bartík, Vladimír (referee) ; Šebek, Michal (advisor)
Data collecting plays an important role in many aspects of today's businesses and quality information is the key to success. Process called Knowledge Discovery in Databases makes possible to extract hidden information that can be used further in our efforts. Main goal of this thesis is to describe an addition to such Data Mining System. Main objective is to create data mining module for NetBeans application, developed for demonstrational purposes by Faculty of Information Technology. New module is going to be able to mine information from Oracle database server via unusual use of Genetic Algorithm. This thesis describes the whole process of module implementation, begining with theoretical basics through coding details to final testing and summary.

Control Unit for Autonomous Vacuum Cleaner
Matějů, Jan ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
This paper is in introduction focused on review of robotic vacuum cleaning and evaluation of available products qualities. However the main focus of this paper is system design of all subsystems, control systems and PCD design of robot electronics. In this paper is also described a method for evaluating approximate distance of robot from the obstacle. There are also described problems of system design of IR proximity sensors. The last part of this work is development of control software for robot and its testing.

NEW ON THE „OLD“ – Brno, Bratislavská - Stará Corner
Červinková, Kateřina ; Odvárka, Antonín (referee) ; Marek, Jiří (advisor)
The territory is located in the city of Brno -center , on the corner position Bratislavska streets and Stara. It consists of several parcels that are currently undeveloped , or the construction of a temporary nature on them. Part of the defined area is now used as a parking lot of the Police of the Czech Republic . From the historic center it divides traffic - a small city street circuit leading to fluctuate. In the vicinity of the area are mostly townhouses with shopping level , built between the 19th - 1st half . 20th century. On the street in Bratislava theater is Joy and Puppet Museum and on the street a few old buildings that are registered in the central register of cultural monuments of the country. The old and the Bratislava streets are typical of the gallery houses with courtyards previously served as business premises . Today, these small companies but totally overcrowded scale and most low companies in this area collapsed or are in a neglected state. The whole area lacks public greenery and foliage is the closest city to the hamlet of liberation, located behind the traffic circle . The concept is based on the position of parcels - on the corner . The idea was to create a peaceful place to live and space for relaxation and meetings. The proposal consists of four masses , to bind and penetrate each other. Each material has its own separate function . Low - on the corner - allows infantry input to a depth of plot and thus offers a view of the surrounding historic facade. Compositions containing residential buildings are raised on the ground floor and the entire floor becomes a public space offers the opportunity to stroll through the old streets of Bratislavská on the street greenery, which in this area is insufficient.

Dynamic Memory Allocation in TinyOS
Križanský, Ján ; Zbořil, František (referee) ; Horáček, Jan (advisor)
This thesis aims for a theoretical and practical comparison of two different approaches to dynamic memory management in TinyOS operating system designated for simple programmable devices. For each of the approaches we were observing different aspects, among others the effectivity of usage of resources, allocation speed and usability from the programmers point of view. Thesis also extends the capabilities of dynamic allocation onto external flash memory. It shortly explains the principles behind dynamic memory allocation and it's application in the area of simple programmable devices with limited resources.
