GNU/Linux Administration Tool for Attached Display Devices
Klang, Petr ; Procházka, Boris (referee) ; Kněžík, Jan (advisor)
The aim of this thesis is to create an application for monitor administration in GNU/Linux system which would be able to save the set configuration and recall that setting later. When a new monitor is connected, the application evaluates all configurations and chooses the most convenient one. The application is run after the screen manager has been started. The thesis is also concerned with the selection of suitable tools, description of implementation, and testing.

Augmented User Interface
Zahrádka, Jiří ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
This thesis falls into a field of user interface design. It focuses on tangible user interfaces which utilize a camera and projector to augment physical objects with a digital information. It also includes description of calibration of those devices. The primary object of this thesis is the implementation of an augmented user interface for application windows management. The system consists of a stationary camera, overhead projector and movable tangible objects - boards. The boards are equipped with fiducial markers, in order to be tracked in a camera image. The projector displays the conventional desktop onto the table and the tangible objects. For example, application windows can be projected onto some boards, while the windows move and rotate simultaneously with the boards.

Establishment of the graphic interface for firewall using Qt4 framework
Štefany, Martin ; Jelínek, Mojmír (referee) ; Matocha, Tomáš (advisor)
The aim of this thesis is to design an application, which will serve as a~graphical interface to the terminal application iptables. iptables is an application which uses the Netfilter framework for managing firewall in operating system GNU/Linux. Graphical interface is a~way how to raise a~comfort of firewall configuration and management, because user doesn't have to remember all of the commands and graphical interface also shows him actual structure and contents of the firewall in a~tree view. Thesis describes format and options of the commands and also the firewall structure and its function in Linux. Designed application is written in C++ language using aspects of object oriented programming and uses Qt4 framework. Qt4 is a~great framework for creating graphical user interfaces, brings a~lot of new classes and methods and extends programmer's possibilities during designing graphical or terminal applications for lots of platforms. Thesis also includes a~manual to designed graphical interface, to the application qIPtables, which user can use to learn the basics of using this application and firewall management.

Technology for comprehensive support of multimedia services in heterogeneous networks
Dosoudil, Petr ; Krkoš, Radko (referee) ; Novotný, Vít (advisor)
The theses explains the Evolution Packet System (EPS) and subsystem IP Multimedia Subsystem (IMS). It also informs how these systems cooperate and through which interfaces the main data and signals between these two technologies are transfered. The thesis includes practical section, in which installation and configuration of sections of the IMS system including its "core", and application and medial server. For verification of the functionality of the system, two dissimilar clients are installed, and emulator WAN is applied for simulation of Internet. The product of the theses is the design of the laboratory exercise drafted in such a way that it can be solved by students less knowledgeable of the issues.

Design and realization of a developement board for BeagleBoard
Ťapucha, Andrej ; Hanák, Pavel (referee) ; Krajsa, Ondřej (advisor)
Contents of the thesis is to design and create an expansion board for the BeagleBoard computer one plate . The first and very important part was to find out all the possibilities for an extension of the computer itself . Choose the right expansion port . To study the possibility distribution of individual pins . Followed by the appropriate extension election districts that demonstrate the function of each enlargement . Test was designed PCB that contains circuits that change the voltage level of the BeagleBoard to protect a mini computer to the testing of each gusset periphery prevent damage to itself or part of the BeagleBoard . The peripherals themselves bind different parts of theoretical introduction. More specifically the extension of the LCD display is selected segment and includes two lines of 16 characters . When the possibility to add additional components were necessary to deal with the shortcomings of the output pins , this problem was solved by using an expander . He extends itself BeagleBoard by another 16 pins . On these pins are connected together on the LCD matrix keyboard . The creation of the board are two circuit temperature sensors , but have a different type of communication using I2C and one second using 1 -Wire bus . The board also contains various other bus outputs , for example, UART bus. It also contains an output pin which can be controlled PWM modulation . The remaining pins are versatile GPIO pins which can be programmed to define a function using the Linux operating system . The result is a final board of the package control programs which make it possible to verify the individual peripherals.

Security of Linux OS
Polách, Milan ; Vychodil, Petr (referee) ; Vymazal, Michal (advisor)
This thesis is focused on the possibility of better networking security operating system GNU/Linux with an appropriate set of rules Netfilter. There was established a program to allow easy configuration of rules for IP Address versions 4 and 6. This program not only allows to set individual rules, but also interfere with the newly required service and decide, how it will be further worked with. The first is the theoretical part describes the network communication with the model TCP/IP, the following is the introduction of Netfilter and outlining the local security. The practical part describes the various technologies and methods used for programming. The result of this work is easy to use program to set firewall rules for IP Address versions 6 with the possibility of deciding on the new established network traffic. The program is designed for new users of the operating system, who want to better secure their computer without the knowledge of Netfilter.

Bezpečnost a ochrana soukromí v informační době
Suda, Jiří
The thesis is focused on personal computer security from the perspective of an ordinary user. This text in the theoretical part mainly introduces the reader to the most common risks associated with the use of a personal computer connected to the Internet. In the practical part based on the collected knowledge was created application used to configure and secure operating system Ubuntu.

How to work with graphics in LaTeX
BOUČEK, Pavel
This work deals with the work with graphics in LaTeX and METAFONT . Are given graphic image formats that are appropriate and possible change to be put in the LaTeX . There is a familiarity with METAFONT and its setting up in Linux (Ubuntu 8.04 LTS distribution). Then there is explained and shown examples of ways you can create images (square, rectangle, circle, ellipse, etc.). In appendix of this work is composed of these individual files one resulting image.
