Medium voltage substation automation using control system COM600 and standard IEC61850
Havelka, Tomáš ; Štaffa, Jan (referee) ; Háze, Jiří (advisor)
This work deals with problematic of standard IEC61850, mainly with chapter IEC 61850-9-2 LE which is commonly known as Process bus communication. There are described advanced tools of the control system COM600 with detail description of their configuration in this work. It also deals with configuration of IEC 61850-9-2 LE with Relion family protection relays and its implementation to the control system COM600. The main aim of this work is focused on configuration of IEC 61850-9-2 standard with protection relays, configuration and detail description of COM600 advanced tools, description of Logic processor, further custom design and appliaction configuration global reset of Logic procesor in control system COM600.

Spectral Analysis of Electromyography Data of Power Lifters
Kofránková, Vlasta ; Otáhal, Jakub (advisor) ; Tlapáková, Eva (referee)
Title: Spectral Analysis of Electromyography Data of Power Lifters Objectives: The aim of this thesis is a description of muscle activity and its measu- rement using electromyography (EMG), description of parameters of EMG signal and their relationship to neuromuscular physiology. The aim of the practical part is an implementation of spectral analysis of EMG data of power lifters when performing 4 series of 5 split-squats carrying loading in one hand. Methods: The spectral analysis of EMG data of 35 athletes is presented. The athletes performed 4 series of 5 split-squats with one sided loading. The loading was 25% and 50% of their body mass and the carrying position was homolateral and contralateral to stance leg. Muscles chosen for measurement were vastus medialis obliquus, vastus lateralis obliquus, gluteus medius and biceps femoris of both sides. The implementation of digital signal proces- sing algorithm was done using Matlab and its Signal Processing Toolbox. The spectral analysis was implemented using discrete Fourier transform with sliding 256-sample window size and 32-sample window increment. The resulting spectrogram was divided into parts based on smoothed EMG. Median frequency for each split-squat was calculated. For the statistical processing we used median frequency differencies...

Localization of individual opioid receptor subtypes in CNS
Lišháková, Michaela ; Hejnová, Lucie (advisor) ; Bendová, Zdeňka (referee)
In last decades, the research focused on opioid receptors has been intensively conducted in order to determine their role in various homeostatic functions, control of movement, neurotransmission and drug addiction. An important factor determining the pharmacologic role of opioid receptors is their distribution within the brain regions as well as at the cellular level. Over the past 40 years, a great deal of information concerning their distribution in the central nervous system has been collected, allowing us to determine their localization and mechanisms of their action. In general, results obtained from previous studies are in agreement. However, there are some inconsistencies that impede the accurate determination of receptor distribution and need to be clarified. This paper aims to summarize results of the previously published studies observing the localization of opioid receptors in the rat CNS. Emphasis is placed on the comparison of results obtained by all available methods.

Study Information Systems at Selected Universities
Cestr, Jan ; Benáčanová, Helena (advisor) ; Černá, Andrea (referee)
The aim of the thesis is to analyze and compare study information systems of four selected universities in the Czech Republic (University of Economics in Prague, Masaryk University in Brno, Jan Evangelista Purkyně University in Ústí nad Labem and Technical University in Liberec) are made from a student's point of view. Important components of the systems, which students needs all the time will be compared in the thesis. One part of the thesis is dedicated to interesting possibilities in the various information systems. The main contributin of the thesis lies in introducing individual components of the information systems, their mutual comparison and the way of their usage. There will be an analysis of their weaknesses and outline of their future development of the information system.
