Control system used in autonomous solar system
Slezák, Pavel ; Dolenský, Jan (referee) ; Vaněk, Jiří (advisor)
This thesis dealing with description and of autonomous solar systems and algorithms for control of decision-making mechanism. Optimal set of these machanism has effeect in raise of efficiency in hole autonomous system. In practical purposes propose create one by using microprocesor ATMEGA8, which measure all electrical data in system and control all decisions of implemented algorithm.

Measurement of the blood pressure using LabView
Slezák, Pavel ; Chmelař, Milan (referee) ; Kolář, Radim (advisor)
This thesis deals with the design of system for blood pressure measurement. The system consists of microphone, amplifier and real time acquisition program using LabView. For determining systolic and diastolic blood pressure origin and ending of Korotkov's sounds is used. The algorithm for this detection is based on bandpass filtering and thresholding also implemented in LabView. As a result of this work, the measured sounds are presented and whole system is described in detail. In conclusion advantages and disadvantages of method are resumed.

Wavelet Filtering of ECG Signal
Slezák, Pavel ; Vítek, Martin (referee) ; Smital, Lukáš (advisor)
The thesis deals with possibilities of using wavelet transform in applications dealing with noise reduction, primarily in the field of ECG signals denoising. We assess the impact of the various filtration parameters setting as the thresholding wavelet coefficients method, thresholds level setting and the selection of decomposition and reconstruction filter banks.. Our results are compared with the results of linear filtering. The results of wavelet Wieners filtration with pilot estimation are described below. Mainly, we tested a combination of decomposition and reconstruction filter banks. All the filtration methods described here are tested on real ECG records with additive myopotential noise character and are implemented in the Matlab environment.

Desulphurisation of flue gas fuidized bed boiler.
Miklík, Tomáš ; Slezák, Pavel (referee) ; Skála, Zdeněk (advisor)
The aim of this thesis is to design a desulphurization device for the fluid boiler. In the fluid boiler, fuel with extremely high sulphur content is burnt and the combustion products are not desulphurized to the required level, therefore it is necessary to build a desulphurization device. The thesis consists of two parts – theoretical and practical. In the theoretical part I stated the emission limits of sulphur dioxide, elaborated possible desulphurization methods and described the sorbets suitable for desulphurization. In the practical part I chose a dry desulphurization method with fluid reactor, to which a dry sorbent on the basis of lime hydrate is dosed. For the required parameters, I designed the whole desulphurization equipment including cloth filters, all necessary silos and major components. It is a design proposal with a layout and a spatial model.

Studie protipovodňové ochrany části povodí Litavy
Slezák, Pavel
The thesis Study of flood prevention in a part of the Litava river catchment describes flood prevention built in May 2012, based on charting of the target location in the area of Slavkov u Brna town. The bulletin of the thesis describes characteristics of the flood, historical events of the most important flood in Czech republic and the topic of flood is debated as well. It also includes flood prevention characteristics. The next part of the thesis analyzes the target area and the flood which happened in Slavkov in 2010. It describes the catchment of Litava river which lies in South Moravia region. The main part if the thesis describes flood prevention systems built in the target area. The last part of the thesis describes current flood prevention systems, concept and suggestions of possible improvements in the Slavkov town.
