Experimental workplace of controlled drive with high dynamics
Rozkošný, Miroslav ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
My diploma thesis deals with the basic principle of the frequency inverter and his construnction. In the next section are analyze the basic properties and characteristics of the using equipment. The main part of this thesis is to investigate the dynamic properties of asynchronous electric motor controlled by a frequency inverter using STARTER. The results of experiments are compared and analyzed.

Digitally controlled filter
Rez, Jan ; Szabó, Zoltán (referee) ; Friedl, Martin (advisor)
This bachelor's thesis deals with design of a functional prototype universal digitally controlled analog frequency filter 2th order. Part of the design is the selection of appropriate filter topology diagram and selection of an integrated circuit. Universal filter will contain lowpass, highpass, bandpass and notch filter. The filter is tuned in cutoff frequency from 100 Hz to 15 kHz. The bachelor's thesis focuses on the circuit analysis of selected concrete structure of universal filter and possibilities of digital control filters. The practical part of this thesis includes PCB design, control software for filter and graphical representation of measured results.

Measurement of wind oscilatory waves on reservoir
Kotaška, Stanislav ; Pelikán,, Petr (referee) ; Špano, Miroslav (advisor)
This diploma thesis deals with the measurement of wind oscillation waves on reservoirs, especially with regard to the determination of wave properties with a focus on the spectral density. The thesis presents the basics of the theory of creation and propagation of wind oscillation waves, the recherche of measuring devices and a description of the pilot measurement with the processing of measured data in the MATLAB environment using the software tool WAFO. Attached to the CD are sample scripts for data processing from the resistance sensor.

Comparing of the parameters for the determination of cardiac dyssynchrony from the ultra-high-frequency electrocardiogram
Jančová, Ivana ; Viščor,, Ivo (referee) ; Jurák, Pavel (advisor)
This thesis deals with the analysis of high-frequency ECG, namely by parameters for the determination of cardiac asynchrony from the amplitude envelopes ultra-high-frequency ECG. In the theoretical part is described the conventional and high-frequency ECG, procedure of their scanning and parameters of the acquired record. Also is described the electrical conduction system of the heart and its blockade. This issue is followed by chapters about cardiac asynchrony and its treatments by biventricular pacemaker – resynchronization therapy. The chapter about resynchronization includes a description of the methods used for the indication for therapy based on conventional and high-frequency ECG. In the practical part are proposed new parameters for determining heart asynchrony from high-frequency ECG, programmed their detection in environment MATLAB and described realization of detection and obtained results. In the last part of thesis is described statistical evaluation of data and is decided about suitability of use the proposed parameters.

Plethysmography for retinal video processing
Plavcová, Daniela ; Valterová, Eva (referee) ; Kolář, Radim (advisor)
Sight is one of the five human senses and is very important for exploring near and far surroundings. However, this is prevented by various eye defects, which may be related to the vascular system of the retina and the pulsations that are observable on it. This work deals with the study of the relationship between the mentioned pulsations and glaucoma. To search for connections between these two aspects, video recordings from the retina are used, the pulsation of which is further worked in the form of a 1D signal, especially in the spectral region.

The framework for application of phase allocation of consumers
Franěk, Vít ; Koudelka, Jan (referee) ; Vyčítal, Václav (advisor)
The aim of this work is to introduce the issue of the smart grids concept, as well as the issue of phase identification sorting from implementation smart grids. The issue of phase identification sorting is described by several possible methods. The work continues by calculating the theoretical network and processing the values measured from the low voltage network and applying the phase identification method based on voltage events. Based on the results, a laboratory task proposal is prepared.

Respiratory biofeedback
Jína, Miroslav ; Chmelař, Milan (referee) ; Janoušek, Oto (advisor)
The aim of this study is to analyze biological feedback, its use and types of biofeedback, which can be used. There is also enumeration of different types of games, which are used for the therapeutic treatment. This work describes in detail the measurement of respiratory biofeedback with chest strap. MP35 acquisition unit and a LabView program, in which the signal is transmitted through the measuring card, is used for measure. This work also describes the role of protocol for measuring respiratory biofeedback. The other important part of this study is the own draft of games made in LabView 2010. This program includes four theapeutic games.
