Scanning a analysing of heart electrical activity and blood pressure before and after the load
Vích, Daniel ; Kolářová, Jana (referee) ; Kratochvíla, Jiří (advisor)
The aim of bachelor’s thesis is familiarization with anatomy and physiology of heart, with setting to electrical activity, scanning EKG before and after the load with Biopac system, scanning of blood pressure before and after the load with auscultation, statistical analysis of acquired data and presentation of measured data in graphical interface Guide of Matlab system. According to the protocol of measurement, scanning of heart electrical activity with the Biopac system, and scanning of blood pressure, with auscultation, was realized before and after the load. Measured data was statistically analyzed with t-test to verify hypothesis, that there is an influence of the load on the watched parameters, and to show the process of statistical verification. Application of this method assumes normal distribution of data, that’s why data was at first tested by Chi-squared and Kolmogorov-Smirnov test to verify their normal distribution. In the next step data was imported into Matlab system. The presentation of measured data is realized in graphic interface Guide. The program contains time domain and spectral analysis, automatic detection of heart rate and analysis of heart rate variability.

Processing of Operating Load Data for Electrodynamic Test Bench
Prouza, Jiří ; Němec, Martin (referee) ; Novotný, Pavel (advisor)
This master's thesis deals with data processing for an electrodynamic test bench. The thesis presents a theoretical overview of signal distribution, determination of fatigue damage from random vibrations and a description of test benches. The next part deals with setting up the test time reduction in GlyphWorks software. The aim of this thesis is to process and create a procedure for an accelerated fatigue test from data measured during an operational test on a polygon. The data are then verified on an electrodynamic test rig using a Skoda Auto dynamic test room. The final part of the thesis contains data evaluation and a guide explaining how to easily create a test in the relevant software.

Real-time spectral analysis in LabVIEW software environment
Vašátko, Karel ; Průša, Zdeněk (referee) ; Rášo, Ondřej (advisor)
This bachelor thesis deals with issues of signal processing and display its spektrum in the environtment LabVIEW. Here is description signal processing theory, description of a block diagram of a spectral analysis and description of the methods for compute power spectral density. In the main part is a description of program developed for real-time spectral analysis. Part contains block diagrams and measurements.

The Applicability of the JONSWAP Spectrum for Wave Events at Small Water Surfaces
Gřegoř, Adam
Task of the research was to determine whether the spectral density (i.e. spectrum) of wind wave events at Hulínská štěrkovna reservoir is the same as the JONSWAP spectrum, which was based at the wave events at partially developed sea. Data about the time course of the water surface elevation at reservoir were processed with use of the MATLAB and WAFO toolbox that was developed by the Lund University.
