Intelligent Tepmperature Sensors Application
Bohutínský, Jaroslav ; Dlouhý, Jiří (referee) ; Čížek, Martin (advisor)
The aim of this study was to acquaint with smart temperature sensors from different producers and to study their properties. The following step was to choose a suitable temperature sensor and a microcontroller (MCU) for measuring and temperature processing. On the market there are products from different firms such as Analog Devices, Microchip, Dallas, Maxim, National Semiconductor, Texas Instruments, Smartec etc. All those firms offer not only temperature sensors, but also microcontrollers. Every producer has its own realization of the inter-sensors communication. In this study there are introduced a wiring diagram of a microcontroller driven module for a temperature measuring making use of a smart temperature sensor and also designs of printed circuit boards.

Modeling of solar power station parameters in GIS
Kučera, Josef ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
The work deals with the modeling of the parameters of solar power plants and the issue of solar energy with its use in the photovoltaic power plants. It uses the geographic information system named ArcGIS. In the beginning of the work, there is the theory. This theory is necessary to understanding the function of the photovoltaic cells, from the beginning to the photovoltaic panels construction. There were analyzed the conditions of the location of the photovoltaic panels in the Czech Republic. Furthermore, the work approaches the ArcGIS and its 3D modeling possibilities. The part of the work deals with the proposal for the selection process of the most suitable location to the photovoltaic panels installing. The main part of the work is the visualization of the 3D models of the locations of interest.

Noise map in GIS
Awadová, Thuraya ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
The aim of this thesis is to create a noise map in a geographic information system. First of all, physical features of sound and the basics concerning the spatial, physiological and atmospheric acoustics domain will be introduced. Furthermore, we will analyse noise and its possible influence on the health of people. Substantial part of this thesis will be devoted to the methodology of noise measurement in urban agglomerations and to the issue of creating noise maps. The methodology of noise measurement in a particular area will be determined on the basis of the theoretical background. Geographic information system ArcView 9.2 from the ARCDATA firm (Ltd.) will be used for creating the noise map. The final noise map will be compared to the current hygienic limits. For comparison reasons an analysis of noise map using software CadnaA, which is used in professional analysis of noise studies, will be included in this thesis too.

Model of tissue heating by KV diathermy
Bažantová, Lucie ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
This thesis deals with the basic theory of the electromagnetic field in the first part and the field interactions with biological tissues. Than describes shortwave diathermy as a technique used for purposes of medical treatment. The aim is to built a model of tissue heating in shortwave diathermy in COMSOL Multiphysics environment, so there is included a description of the programming environment, including the mathematical method that COMSOL uses for calculations. The output of the whole work is a model of the lower limb in the knee part and display the results after his diathermy heating.

Visualization of vocal cords movement
Kutálek, Libor ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
The main object of these work is show how does vocal organism of a man work and how can we examine it. We are familiarized with methods for objectification of investigation glottis by the help of modern videotechnology. In this work we could found draft of stroboscopic source of light, whitch would be used for investigation glottis in videolaryngosrtoboscopy. In the following part of this work is shown experimental examination functional section, whitch would me used for investigation in practice.

Analysis of AVG signals
Mikauš, Jakub ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
MIKAUŠ, J. Analysis of AVG signals. Brno: Brno University of Technology,The Faculty of Electrical Engineering and Communication, 2008. 33 s., 1 příl. Supervisor of bachelors’s thesis doc. Ing. Jiří Rozman, CSc. This thesis deals with AVG (arteriovelocitogram) signals analysis, that’s gained non-invasive measurment by the help ultrasound diagnostic equipments. The gained data of these signals are make use of specify diagnosis patients with ischemic disease. For this analysis is take advantage of algorithm using neural network of program enviroment MatLab. Variety topologies of multiply neural network were verified and results evaluated.

Eliminator of dental calculus
Halaš, Rostislav ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
Tato práce se zabývá návrhem ultrazvukového odstraňovače zubního kamene pracujícím na frekvenci 27 kHz s maximální intenzitou ultrazvuku 5W/cm2. Popisuje mechanismus vzniku zubního kamene, důsledky na zdraví a metody jeho odstraňování. Zaměřuje se na principy odstraňování s využitím ultrazvukového vlnění. Dále je sestaveno funkční a blokové schéma. Na základě těchto znalostí je proveden návrh a výpočet jednotlivých částí aplikátoru. Výkonové a napěťové poměry jsou vypočítány od aplikačního hrotu směrem ke generátoru. V neposlední řadě je popsán návrh obvodů buzení měniče i kontrolních obvodů. Schémata jsou doplněna výkresy desek plošných spojů a soupiskou součástek.

Position system design
Balogh, Jaroslav ; Čížek, Martin (referee) ; Čech, Petr (advisor)
The purpose of this diploma thesis was to explore possibilities, design and build 2D position system driven by PC via USB. ATmega16 and FT232R were used as the most important parts of hardware solution. Software for control of the position system was designed in C++ Builder and it can run under MS Windows XP. This work is based on semestral thesis and in future can be used in other applications or modified. 2D position system will be later used by UBMI in education and scientific applications.
