Granular Synthesis in Music Production
Pečinka, Pavel ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
Cílem této práce je navrhnout a vytvořit aplikaci pro granulární syntézu, využitelnou v hudbení produkci. Aplikace je implementována jako VST3 zásuvný modul s využitím frameworku JUCE a programovacího jazyka C++ a je schopná propojení s programy typu Digital Audio workstation, zkráceně DAW, což jsou programy sloužící jako centrální bod pro hudební producenty, kde mohou mimo jiné vytvářet nové zvuky, provádět mixování skladeb a vytvářet zvukové nahrávky. Tento zásuvný modul je navržen jako sampler a je schopen nahrát zvukový soubor obsahující audio data, která dále využívá pro další zpracování a následné přehrávání. Z vyhodnocení uživatelského testování vyplývá, že je tato aplikace použitelná pro hudební produkci jako nástroj pro granulární syntézu.

Signal processing in ZigBee system
Miloš, Jiří ; Bradáč, Zdeněk (referee) ; Hanus, Stanislav (advisor)
Master's thesis The Signal Processing in ZigBee System is focused on properties of Physical Layer of ZigBee (standard IEEE 802.15.4 - 2003). The work consists of three parts. The first part contains common view on using and properties of ZigBee. The next part focuses on the Medium Access Control Layer and in detail on the Physical Layer. There described signal processing in the Physical Layer in individual radio bands. The last part of the project contains the process of modeling in the MATLAB for both models of system ZigBee (bands 868/915 MHz and 2450 MHz). The last part of thesis deals with the simulations of BER depending on Carrier-to-Noise Ratio. Also examined the coexistence of systems operating in the same or a nearby frequency band. Based on the results of simulations there are given recommendations for the use of the ZigBee system in minimizing BER.

Development And Verification Of A New Method For Measuring The Stiffness And Damping Properties Of Joints In Parallel Kinematic Structures
Kolouch, Martin ; Tomáš, Jiří (referee) ; Knoflíček, Radek (advisor)
In this dissertation is presented the development of a new measurement method for the stiffness and damping characteristics of a joint in a parallel kinematic machine tool. The main contribution of this method is specially for applications, that demand accurate information about stiffness and damping parameters from assembled parts of machines tool. Methods for compensation of deformations in machines tool, that are carried out by control, belong to these applications. Another contribution of this work is the technical implementation of the proposed principle of the new method. At this point the focus of the work was devoted to signal processing, that differs in a certain degree from other types of signal processing methods, that are used in other dynamic measurements, e.g. modal analysis. One of the main requirements was the possibility to consider the nonlinear behavior of the measured structure. In another chapter the modified signal processing method was used for measuring a joint in a test rig. The results were compared with results from other measurement methods. On account of this comparison the statement was made that the new method can be used for measuring the stiffness and damping parameters of machine parts. Finally the new method was applied to measure the properties of a joint, which was built in a machine tool. Moreover, the problems, that appeared during the measurement, were also described.

Time Frequency Analysis of ERP Signals
Bartůšek, Jan ; Provazník, Ivo (referee) ; Černocký, Jan (advisor)
Tato práce se zabývá vylepšením algoritmu pro sdružování (clustering) ERP signálů pomocí analýzy časových a prostorových vlastností pseudo-signálů získaných za pomocí metody analýzy nezávislých komponent (Independent Component Analysis). Naším zájmem je nalezení nových vlastností, které by zlepšily stávající výsledky. Tato práce se zabývá použitím Fourierovy transformace (Fourier Transform), FIR filtru a krátkodobé Fourierovy transformace ke zkvalitnění informace pro sdružovací algoritmy. Princip a použitelnost metody jsou popsány a demonstrovány ukázkovým algoritmem. Výsledky ukázaly, že pomocí dané metody je možné získat ze vstupních dat zajímavé informace, které mohou být úspěšně použity ke zlepšení výsledků.

Radar Signal Processing
Komora, Matúš ; Maršík, Lukáš (referee) ; Zemčík, Pavel (advisor)
This work is devoted to signal processing and evaluation of Doppler radar. By Signal processing is specifically means to calculate the velocity of the object based on the responses received from the radar. Mathematical method used is a discrete Fourier transform, which is one of the standards in the analysis of signals. Because of the radar signal is random, discrete Fourier transform itself is not sufficient to obtain accurate results, so it is necessary to use other methods that try to minimize weaknesses.
