Visualization of forward error correction securing by block and cyclical codes
Fančal, Petr ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
This bachelor thesis provides an introduction to the principles of forward error correction securing by linear block and cyclical systematic codes and its visualization by educational application. First part of the thesis contains comprehensive theoretical base of principles of forward error correction securing and capability of linear block and cyclical systematic codes. Second part describes the educational application, realized in graphical user interface GUI of MATLAB. This application step by step visualizes parts of procedures of securing, error detection and correction. Its main benefit is its usability as illustrative teaching aid.

Multifunction data acquisition, measurement and control device
Trávníček, Ivo ; Vlachý, David (referee) ; Grepl, Robert (advisor)
The thesis deals with and tests the Multifunction data acquisition, measurement and control device. The unit is based on the microcontroller ATmega, which was programmed in the language C. The unit contains functions for the measurement of physical quantify, filtering record, regulation of the dynamic systems and communication with PC. Configuration of the unit is real-time in special software created in the language Matlab or by a terminal. The purpose of the unit is controlling a DC motor by the PID regulator, long-term measurement of temperature or measurement of acceleration by an accelerometer.

Photopolymer length variation measurement
Novotný, Jan ; Vejlupek, Josef (referee) ; Matějásko, Michal (advisor)
This thesis deals with development of a special measuring device designed to measure changes in lenght of a photoactuation polymer. The length of a sample of the polymer shortens by tenths of a milimetre by being lit by intensive light. The sample has to be preloaded by force. The data are processed by designed electronics and recorded in a computer in a utility application, developed for this purpose. The thesis is realized in cooperation with the Centre of polymer systems of the Tomas Bata Univerzity in Zlín.

Instance based learning
Martikán, Miroslav ; Polách, Petr (referee) ; Honzík, Petr (advisor)
This thesis is specialized in instance based learning algorithms. Main goal is to create an application for educational purposes. There are instance based learning algorithms (IBL), nearest neighbor algorithms and kd-trees described theoretically in this thesis. Practical part is about making of tutorial application. Application can generate data, classified them with nearest neighbor algorithm and is able of IB1, IB2 and IB3 algorithm testing.

Turbo codes and their applications
Ploštica, Stanislav ; Krajsa, Ondřej (referee) ; Šilhavý, Pavel (advisor)
This Diploma thesis aims to explain the data coding using turbo codes. These codes belong to the group of error correction codes. We can reach the high efficiency using these codes. The first part describes process of encoding and decoding. There are describes parts of encoder and decoder. Principle of encoding and decoding demonstrate a simple example. The end of this part contains description of two most frequently used decoding algorithms (SOVA and MAP). The second part contains description of computer program that was made for using as teaching aid. This program was created in Matlab GUI. This program enables to browse error correction process step by step. This program contains graphic interface with many options and display results. In the third part is described program created in Matlab Simulink that was implemented into the TMS320C6713 kit and there is description of measuring procedure. For verification of efficiency of turbo codes was measured any parameters. Some of these parameters are: number of decoding iterations, generating polynoms and using of puncturing. The last part contains measured value and result evaluation.

Analysis of oscillations of single-mass systems with two degrees of freedom
Scerbina, Vadim ; Marcián, Petr (referee) ; Lošák, Petr (advisor)
The focus of this bachelor's thesis is the division, modelling, simulation, and subsequent analysis of single-mass systems with two degrees of freedom, which can replace various mechanical systems under certain assumptions. Part of the system division involves deriving general cases that involve situations where the interdependence between mutually perpendicular coupling elements is considered. The Simulink environment, based on the MATLAB platform, was used for computational simulation. The simulation results were processed using MATLAB. To enhance user experience, applications were developed in the MATLAB GUI environment for each case of the examined systems. The results of the analysis indicate that the mutual interaction of coupling elements has a significant impact on the simulation, with the position of the main system resonances being most affected. The developed method for solving systems of differential equations using Simulink and MATLAB could be applied to systems with a larger number of differential equations.
