Lab tasks for dynamic code analysis
Košina, Petr ; Přinosil, Jiří (referee) ; Sysel, Petr (advisor)
The thesis focuses on static and dynamic analysis in software engineering. Static analysis involves examining the source code without executing it, whereas dynamic analysis focuses on executing the code and testing its runtime behavior. The thesis explores various techniques and tools for both types of analysis, including their advantages and limitations. Additionally, the content includes research on the implementation of dynamic code analysis methods across different operating systems. Emphasis is placed on comparing both methods and their application in real-world software environments. Specifically, it provides practical laboratory exercises designed to help students better understand the issues related to dynamic analysis.

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.

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.

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.
