Realization and implemention of RDS message management software
Heralt, Jiří ; Zezula, Radek (referee) ; Koutný, Martin (advisor)
The purpose of this work was realization and implementation of two applications for the management of Radio Data System (RDS) messages. These applications will be subsequently used in the Czech Radio Ostrava to support two RDS services, namely the Traffic - Announcement Identification and Radiotext. Both applications are secured against unauthorized use by incompetent users through a password - protected access, access rights and encryption of passwords in initialization files. The text of this work is divided into three parts. The first describes the system RDS and services provided by it and implementation of RDS in the Czech Radio Ostrava. The second part deals with the realization of both applications and the last part describes the implementation itself. The work shows all applications windows. Work also includes all the flow charts. The list of all broken down by subroutines is given in the appendix.

Anti-Error Coding Systems with Block Codes
Pacher, Jakub ; Zezula, Radek (referee) ; Němec, Karel (advisor)
This work deals with selection and proven suitable error-correcting code securing aggregating errors. First we give analysis anti-error coding system and requirements rapid/fire at them. The next text is focusing on survey and characteristics often used codes, mainly Fire, Hamming and two BCHs codes. After an explanation of Hamming code use, the text describes verification of proper function anti-error system in the MathCad enviroment.

Marketing strategy for Fit Center
Zezula, Radek ; Snopek, Radek (referee) ; Mallya, Thaddeus (advisor)
This bachelor work focuses on analyzing limitations of marketing strategy of a fitness center. It tries to establish how these shortcomings could be eliminated and in achieving this goal different tools like marketing mix analysis and questionnaire are used. Based on the feedbacks from the customers who filled the questionnaire and discussion with the management of the center, some measures on how to properly react to each individual customer demand and increase attendance and popularity of fitness center were suggested.

I2C-RS232 converter
Bednařík, Martin ; Zezula, Radek (referee) ; Zeman, Václav (advisor)
The objective of this thesis is to get familiar with function of I2C bus and microcontrollers AVR and study the principle of connecting microcontroller with the other circuits via this bus. Another goal is to design a device which will enable a communication between personal computer and controlled circuits. A part of this project is production of necessary microcontroller software equipment and to develop own communication protocol. Another output of this project is getting an overview of applied technologies, study possibili-ties of their additional usage and potential enlargement of device with another components.

MHP application for remote control of actuating unit
Šot, František ; Zezula, Radek (referee) ; Kohoutek, Michal (advisor)
The aim of bachelor´s theses is reading up of general and transmitting string structure of digital video broadcasting terrestrial (DVB-T). Read up a possibilities of IRT- playout server and DVB-T modulator, further apprise of thermoregulation system ETATHERM and consequential creation of MHP application for system regulation. Thermoregulation system ETATHERM is possible to control by remote access, which means in our case by e-mail client. This system contains control unit ETH1 mod, KomWin program, Imodul program and regulation head of heating engineering. Created platform of home multimedia device (MHP application) is user interface, which communicate by simple mail transfer protocol (protocol for sending electronic mail) with thermoregulation system ETATHERM by remote access, User interface enables to set different characteristics of regulation such as room, temperature, time of the start and time of the end. The application is testing in simulation IRT MHP RI program and on set-top box DVB Strong 5510. By the help of application we create regulation command, which is possible to send to predefined e-mail, where it is worked up by Imodul program, which supplies receiving, confirming, cancelling and deleting regulation commands. Further it is worked up by KomWin program, which is linked to control unit ETH1 mod and this control unit starts configured regulation procedure. The application is create in Java code in development environment NetBeans 5.5.1.

Methods Decoding Convolucional Code
Vlček, Peter ; Zezula, Radek (referee) ; Křivánek, Vítězslav (advisor)
Convolutional codes belongs to among linear tree codes. There are codes used for channel coding. At build - up project, then comparison separate algorithms were gateway into the account Viterbiho algorithm, Stack algorithm, Stack- bucket algorithm, Fano algorithm and Feedback decoding. Was built-up suggestion convolutional encoder and decoder, which at his activities make use of Viterbiho algorithm and Stack algorithm, what serves for contrast of both methods. It turned out, that the Viterbiho algorithm get past in the main for codes with smaller compulsory longitude, because has stand-by cost quantity calculated effect. At Stack algorithms is quantity calculated effect dependent on longitude received sequence, what may result in much smaller number calculated effect, however at very noisy channel is able to state, that the calculated effect will much more as with Viterbiho algorithm. Nothing less is Stack algorithm or his variation Stack- bucket algorithm used primarily on codes with bigger compulsory longitude. Feedback decoding is gainst for simple construction decoder acceptable alternative toward decoding most likely and to sequential decoding.

Neural networks in audio signal watermarking algorithms
Kaňa, Ondřej ; Smékal, Zdeněk (referee) ; Zezula, Radek (advisor)
Digital watermarking is a technique for digital multimedia copyright protection. The robustness and the imperceptibility are the main requirements of the watermark. This thesis deals with watermarking audio signals using artificial neural networks. There is described audio watermarking method in the DCT domain. Method is based on human psychoacoustic model and the techniques of neural networks.
