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.

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.
