Acoustical simulation of going car
Lacko, Tomáš ; Horka, Michal (referee) ; Sigmund, Milan (advisor)
This project includes an overview of different processing methods phonograms. It focuses primarily on time - frequency analysis carried out using Fast Fourier Transform (STFT). The main essence is to evaluate the time - frequency analysis of recorded motor vehicle, driving at different options, together with an analysis of driver activity in these variants. Based on the results of the analysis deals with the creation of synthetic audio signals of motor vehicle records. Further addresses the creation of the program for acoustic simulation engine is running smoothly when driving a car. Processing recorded signals and their evaluation is transferred using Matlab 7.7.0 ( R2008 )

Suppression of powerline interference in ECG signals
Lacko, Michal ; Hrubeš, Jan (referee) ; Kozumplík, Jiří (advisor)
This project includes survey of various methods ECG signal filtering, to suppress of powerline interference. It is specialized especially on properties which affecting the quality of filtration. The main essence of project is evaluation of the proposed methods in terms of quality and the least possible distortion of the resulting ECG signal. The work is focused on linear, adaptive filtering and filtering using discrete wavelet trans-form. Signal processing and evaluation of descriptive parameters are transferred using the graphical interface GUI in the program Matlab 7.7.0 ( R2008b ).

Dictionary Data Management System
Šimek, Petr ; Kouřil, Jan (referee) ; Smrž, Pavel (advisor)
The bachelor's thesis deals with electronic dictionaries that are stored in the format Lexical Markup Framework. It deals with their analysis of the correctness of the conversion to other formats, the unification of used terminology and mass changes data. The scripts in Python3 were created for these purposes.

Impedance matching of a transmission line in Matlab
Straka, Zdeněk ; Láčík, Jaroslav (referee) ; Štumpf, Martin (advisor)
This bachelor’s thesis is aimed at the impedance matching of transmission lines and at understanding of the Smith chart plotting. In the text are described the basic features of the transmission line theory, i.e. the behavior of voltage and current along the lines in different situations. The construction of the Smith chart is described in detail. The Smith chart serves for the transformation of impedance and reflection coefficient along the transmission line. In conclusion, advantages and disadvantages of the matched transmission line are discussed. The project presents a demonstration program using examples. The program is used for illustrative example of the matched impedance and the behavior of voltage and current along the lines in different situations
