Graphical Educational System
Hotař, Roman ; Seeman, Michal (referee) ; Štancl, Vít (advisor)
The purpose of this thesis is the proposal of the issue of education software for learning algorithms. Work approach to the problem, both from a theoretical point of view, of education and learning to new things, so and more important from a practical point of view for introduction to the process algorithmization. It also discusses the problem of learning algorithms in Czech schools and describes the resulting program, which was created along with this thesis. Contribution of this thesis is the summary of the requirements for the software and implementing software of this type, where is possible to demonstrate the problems and requirements of the draft programs of this kind. This thesis also describes the reactions of teachers to created application.

SW for control tests and generating reports
Dočkal, Michal ; Šťastný, Ladislav (referee) ; Franek, Lešek (advisor)
The content of this work is the development of an application that serves as a graphical interface for running tests and generating reports. At first is marginally analyzed the process of measuring and recording, then the technology used in the development is described. As next, suitable implementations is proposed. Finally createed application is described, including outlining possibilities for further development.

Sniffer for power lines communication
Zapletal, Radek ; Šťastný, Ladislav (referee) ; Franek, Lešek (advisor)
This work deals with the design and development of universal software packet analyzer for capturing, analysis and filtering Power-line communication (PLC). The input data are provided by hardware packet analyzer over RS-232 interface. The application will find use in the area of Smart Grids and Smart Metering. This work describes both of these areas including sniffers and suggests several possible solutions with a selection of the best one and description of the development process.

System for the support of comparison of algorithms for noise reduction in audiosignal
Bartoš, Jan ; Smékal, Zdeněk (referee) ; Míča, Ivan (advisor)
The main purpose is to create a system for working with audio-signal, which is user-friendly and ready for next expansion. The program is developed in the Qt library of the Linux Ubuntu 7.4 operating system with using of C/C++ language. Another purpose is to demonstrate the functionality of the program on simple channel speech. To this aim there are implemented algorithms of the spectral subtraction and of the spektrogram's tresholding with using of FFT algorithm. The parts of the work are the teoretical part of the GUI implementation and the implementation of denoising methods, a partial description of the program and his structure and instruction manual.
