Drupal editing system
Procházka, Jaroslav ; Koutný, Martin (referee) ; Martinásek, Zdeněk (advisor)
My Diploma thesis deals with the content management system Drupal, further explores the open source content management systems and puts the attention on Drupal 7. Analyzed the possibility of migration of Drupal version 6 to version 7. When you migrate, you must be aware of already existing structure, Web presentations already created user accounts, Web sites, databases. In the practical part of the Thesis is carried out on the migration of the Web slide show version of Drupal 7. After the migration, checked the correctness and functionality of all modules and Web content. Deployed a new content management system Joomla 2.5. The final presentation is supplemented by the necessary modules to optimize SEO. Configured with all necessary parameters for SEO. Influence of optimization tested and evaluated in detail the results obtained. Analysis and testing focused on Google and Seznam. The results of the analysis carried out optimization of Web presentation. All of the implemented modules updated and tested for functionality. In the website is implemented a language switch, and revised the contents of the pages. Carried out a complete testing of a Web presentation.

Realization of narrowband powerline modems
Kubíček, Lukáš ; Krajsa, Ondřej (referee) ; Koutný, Martin (advisor)
This master's thesis deals with a narrowband power line communication technology (PLC) and focuses on the potential use in the sensor networks. This thesis addresses both the structure and basic properties of PLC standard and possible use of this application in practice. The main part of this work is implementation of the PLC networks with IC ST7570 of STMicroelectronics. As an example of practical use of PLC technology, this network is connected to the computer where the data from the sensor (meter) connected to a PLC modem, stored in a database using a PHP script as presented by the Internet. Problem solving in this thesis focuses primarily on the simplicity and universality of the resulting applications.

Automatic counting of people
Mitáček, Štěpán ; Číž, Radim (referee) ; Koutný, Martin (advisor)
This effort deals with the problem of effective counting of people in the room. Although more companies deal with this problem at present, but their systems are very expensive. For this reason I strive to find a cheaper solution for counting people using active infra- red sensors by which I want to perceive the passage of a person through the door or his presence in the room. In addition it is necessary to take into consideration the other various situations that may occur when a person comes into the room or when he/she leaves. These situations can be in many cases similar, but the output should be able correctly distinguish the possibilites. The result of this effort is detector which is able to detect correctly one person or more people passing the door. People can browse through a door one behind the other, but they also can pass in the doorway in random combinations.

Security of real time multimedia data transmission
Otoupalík, Petr ; Koutný, Martin (referee) ; Hošek, Jiří (advisor)
This thesis deals with technology and security of real-time multimedia data transmission. The possibilities of the security of a multimedia data transfer and the mechanisms defined for the security of the signaling protocols SIP and H.323 are described with the view of security. The possible attacks on the real-time transfers are also mentioned. The basic requirements on the safe and reliable data transfer are specified. The main part of this thesis is focused on the security analysis of the data transmission of the selected communication clients, which use different security methods. The last part of the thesis deals with realization of simple attacks on multimedia data transmission and also on the SIP protocol.

Design of practical tutorials for the OPNET IT Guru simulation environment
Matzová, Martina ; Koutný, Martin (referee) ; Hošek, Jiří (advisor)
This thesis deals with the design of three labs in the simulation environment OPNET IT Guru. The first lab demonstrates the differences between the RM OSI transport layer protocols - TCP and UDP. The second lab discusses the role of ICMP protocol and its most famous feature - PING. The third lab is devoted to Application Characterization Environment (ACE) module, which is included in OPNET IT Guru. Theoretical background is provided for all of the mentioned topics. All designed labs can be used to teach at the Faculty of Electrical Engineering and Communication of BUT on subjects dealing with network technologies.

Modelling the wireless transmission channel in OPNET Modeler simulation environment
Spiglazova, Světlana ; Koutný, Martin (referee) ; Hošek, Jiří (advisor)
This diploma thesis deals with modeling wireless transmission in simulation environment OPNET Modeler. In theoretical part, there is described the very substance of spreading the signal via electromagnetic wave including impact of the surroundings that affects the spreading. These impacts have an influence on described selected parameters of wireless transmission of the signal characterizing its quality. Furthermore, there is described the OPNET Modeler setting, which allows designing the wireless transmission and by means of simulation verifies its functionality and acquires it is parameters. The transmission of the signal from transmitter to receiver itself is divided to individual steps, which are described in detail considering the implementation in aforementioned environment. In practical part, there is configured the basic model of wireless network and also executed series of simulations with different variants of commonly adjustable basic parameters of the transmission, as signal modulation, antenna types and network topology. Additionally, attention is turned to the stages of transmission itself, philosophy of their cooperation based on sharing the information via data units called TDA and their implementation in source code of the C++ language called transmission models. Based on these foundations is beyond beforehand defined created new user TDA and by means of simulation verified its correct implementation within packet switching. Values of the selected including user TDA are written in the window of simulation console with the help of the C++ language. Acquired results of the simulations are analyzed and documented in the conclusion. Source codes are available in the diploma thesis appendix.
