Security system with mobile phone communication
Ulbrich, Jakub ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
This thesis deals with the question of electronic security systems. In the forepart are described electronic security system components such as keyboards, detectors, alarm devices etc. Various methods of security or de-security of properties, trespassing and other events detection methods, and ways of alarm calling are described there too. The next part of the master’s thesis focuses on the construction of an alarm system which is designed for security of a common-size flat with one entry. The system manages to control up to four movement detectors. The operation of the system is handled by a 16 button keyboard, and easy orientation is provided thanks to a liquid crystal display. The alarm is signaled by an indoor alert siren, however, other alarm announcing devices with an input matched for the log. 0 or log. 1 reception can be connected too. The system contains communication equipment (mobile phone) which signals alarm at a distance to the three telephone numbers. User can use a distance control by text message to unlock system or to determine its status. The system is controlled by the microcontroller AVR ATmega16, the product of Atmel company. A brief description of all components of the electronic alarm system is included in this work.

Small vehicle motion control
Štark, Zdeněk ; Valach, Soběslav (referee) ; Macho, Tomáš (advisor)
In this thesis, a simple small vehicle powered by differential chassis was projected and constructed. The vehicle is controlled manually with the help of user program on personal computer (PC). The software equipment allows recording trajectory run by the small vehicle and then repeating it automatically. The operation system of the small vehicle is based on microcontroller ATmega16 series. Communication between the microcontroller and PC is carried out through RS232 serial bus. The vehicle has digital compass and five reflex sensors that serve for obstruction detection in the closest vicinity of the vehicle. Power unit of the vehicle consists of seven NiCd cells with the capacity of 500 mAh. Propellant unit is powered directly from NiCd cells. Voltage of 5 V for feeding of the control electronics is gained through the set up clasp source of voltage connected to NiCd cells.

Spectral anlysis with superesolution
Vintera, Jiří ; Macho, Tomáš (referee) ; Čejka, Miloslav (advisor)
VINTERA, J. Spectral anlysis with superesolution. Brno: University of Technology, The Faculty of Electrical Engineering and Communication, 2008. 85 p. Master’s thesis. This thesis deals with the topic of super-resolution spectral analysis in the Signal Processing Toolset. The Signal Processing Toolset is a software component of the LabVIEW 8.1. program equipment. The thesis consists of three main parts. In the first part the basic theoretic concepts of the Model-Based Frequency Analysis are described. The second part serves as a user manual for the super-resolution spectral analysis in the Signal Processing Toolset. The last part describes the application of the theory introduced in the first part, by means of testing the properties of the methods used by the Toolset.

Comparison of technogies for creation of information systems
Hubený, Lukáš ; Macho, Tomáš (referee) ; Holek, Radovan (advisor)
The topic of this master thesis is a comparison of the technologies for information systems creation. There are compared four fundamental technologies: Php, ASP.NET, JSP and Perl. The comparison of these technologies have two main stages: The first stage is mostly theoretical and demonstrate theoretical advantages and drawbacks of these platforms. The second stage demonstrates on some short examples advantages of platforms during information systems programming. Co-operation with database systems is compared too.

Tools for Automating the Workflow Processes
Vančura, Tomáš ; Macho, Tomáš (referee) ; Holek, Radovan (advisor)
The the thesis deals with tools for workflow processes automation. It describes in general what workflow is. It also briefly describes tools such as MS BizTalk Server, SAP NetWeaver, IBM WebSphere, ORACLE BPEL. The main part deals with Windows Workflow Foundation. This tool is decribed in detail together with its parts workflow runtime, workflow instances and workflow activities. One part of the thesis is a application, which uses all the possibilities of Windows Workflow Foundation.

Inteligent thermometer
Wirt, Tomáš ; Valach, Soběslav (referee) ; Macho, Tomáš (advisor)
This graduation thesis deals with temperature sensors and theirs connection to the microcontroller MCF52233. In the introductory chapters there is description of the principles and characteristics of the heat sensitive elements and theirs abilities of connection to the microcontrollers. Further there is a real proposal and description of the connection realization with sensors DS1620 (intelligent temperature sensor which communicates via serial synchronous link), DS18B20 (intelligent temperature sensor which communicates via 1-Wire bus), LM335 (precise temperature sensor) and KTY81-210 (resistance temperature sensor which is made of silicon). There was a need to create software for the communication between sensors and microcontroller MCF52233. Communication with the superior PC computer was done by USB interface. Software background was created to show temperature readings on the PC computer. Besides the realized USB communication there was done theoretical analysis of the communication via Ethernet bus. On the enclosed CD you can find testing software for the microcontroller and PC computer which allows you to get temperature values from sensors and show them on the screen of the PC computer.

Multicinema information system
Baxa, Radek ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
The thesis deals with information system for multicinema. In general, it is about project and largely realization software which can manage relevant information in multicinema organization. The first part is introduction and study of programming platform for construct information systems. In general they are PHP, DOT NET and J2EE. There is also description of related technologies for remote desktop and web clients too. The second part is about analysis. The most important chapters contain determination requirements and database schema for persistent storage data. At the end of this part analysis class diagram is mentioned too. The third part is about projection and about software realization using J2EE technologies EJB, JSP and so on. Selected segments of the system are described using UML diagrams. The appendix contains index to abbreviations. Main addition is compact disk containing complete documentation and created software (source codes, binaries).

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.
