Establishment of the graphic interface for firewall using Qt4 framework
Štefany, Martin ; Jelínek, Mojmír (oponent) ; Matocha, Tomáš (vedoucí práce)
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.

Zigbee node for monitoring of electric energy consumption
Štefany, Martin ; Mráz, Ľubomír (oponent) ; Šimek, Milan (vedoucí práce)
Master's thesis designs a device for monitoring of electric energy consumption with ability to send measured data wirelessly using ZigBee technology. Theoretical part describes basic principles for measuring electric power and energy and also a possibility of digital measurement. Thesis provides short overview of already existing solutions for electric consumption measurement available on the market as well. Further the ZigBee standard is described together with one of its software implementations named BitCloud from Atmel Corporation. Design of the device deals with the selection of suitable integrated circuit for the consumption measurement and optimal voltage and current sensors. Then also its connection with the wireless module named ZigBee using SPI bus, power supply for the entire device and also the design of PCB. There is also a firmware implementation for the designed device based on BitCloud. Description of the firmware together with calibration process implemented is also part of the thesis. Finally, basic device testing and packet analysis of communication between designed device and ZigBee network coordinator is described.
