Methods for detection of QRS complex
Lysák, Karel ; Chrobák, Martin (referee) ; Smital, Lukáš (advisor)
This bachelor’s thesis deals with methods for detection of QRS complex in the ECG signal. There are described selected detection approaches, basic information about ECG and electrical activity of cardiac muscle. There is also described detailed procedure for the implementation of the three methods of detection in MATLAB and an assessment is made of the detectors tested on the CSE database. There are described some methods of cluster analysis and their possibilities of usage. There is also a description of detectors created by using cluster analysis and their efficiency is tested on the CSE database. Finally, there is a comparison of detection rates of all created detectors.

QT Interval Measurement
Váňa, Tomáš ; Chrobák, Martin (referee) ; Kozumplík, Jiří (advisor)
This semestral thesis deals with QT interval measurement. The theoretical part of the work describes ECG delineation, QT interval and methods for detection Q onset and T offset. The practical part of the work describes R wave detection, preprocessing of ECG signal and implementation of selected methods for QT interval measurement. Selected algorithms were evaluated on the standard CSE database. Detected positions were compared with reference values. Result of this work is evaluation of results.

Cluster Analysis
Chrobák, Martin ; Ronzhina, Marina (referee) ; Kozumplík, Jiří (advisor)
This master’s thesis is engaged in usage of cluster analysis for ECG signal to separate normal QRS complexes from abnormal ones. For this, it is used two algorithms created in professional computing interface MATLAB. The outputs from this master’s thesis are dendrograms, which divide QRS complexes into abnormal and normal clusters, and Pearson correlation coefficients.

Sampling Rate Conversion
Chrobák, Martin ; Provazník, Ivo (referee) ; Kozumplík, Jiří (advisor)
This bachelor’s thesis is engaged in design of procedure for change of sampling rate of EKG signal using 3 methods: with positive integer factor D/I, with any factor (I=8) and with any factor (I=16). Sampling rate conversion should be realized from 500 to 360 Hz and from 360 to 500 Hz in time and frequency part of signal. For this, it is used a professional computing interface of MATLAB, which is perfect for processing of signals. The output from this work should be recommendation which filters (with how long impulse characteristics) are useful for this change of sampling rate.

Production of aquariums Brno Pavlica
Chrobák, Milan ; Kotek, arch Jakub (referee) ; Boleslavská, Yvona (advisor) ; Bečkovský, David (advisor)
This bachelors final project is based on an atelier project of the sixth semester of the bachelors study program of architecture of civil engineering. This project is based on the original design. The task was to design an object suitable for production and show of large-sized interior aquarias made by company PAVLICA Akvária, originaly located in Uherský Ostroh, and its administration. The plot, where the object has to be located, is labeled as brownfield no. 0811. This area is situated in Horní Heršpice, Brno. Designed object respects the surrounding terrain and copies it with its staging volume. The building is reflecting personal and profesional approach of the company to every contract. The building is two-storey. On its ground floor, there is situated showroom for presetation of company and for event happenings. On the second floor, there is administration offices, staff facilities, support areas, production itself including stock.

Cluster Analysis of ECG Signals
Dvořáček, Tomáš ; Chrobák, Martin (referee) ; Kozumplík, Jiří (advisor)
This bachelor thesis is engaged in problematics of automatic cluster analysis for ECG sinals. This bachelor thesis contains theory of pathology in cardiac rhythm and problematics of cluster analysis. Based on a gained knowledge, set of symptoms is made, which are used for cluster analysis using MATLAB interface and which results are evaluated.

Analysis of the gaming performance in professional football
Chrobák, Marek ; Buzek, Mario (advisor) ; Frýbort, Pavel (referee)
Název: Analýza herního výkonu v profesionálním fotbale Cíle: Hlavním cílem této práce je detailní rozbor všech vstřelených branek v české nejvyšší fotbalové lize v ročníku 2010/2011. Následně tyto vstřelené branky zpracovat z kvantitativního a kvalitativního hlediska podle vytvořených kritérií, popis modelových situací a komparace s obdobnými analýzami ze světového fotbalu. Metody: V naší práci jsme použili metody kvalitativní a kvantitativní analýzy a metodu pozorování. Pomocí detailního pozorování a rozboru jsme všechny vstřelené branky rozdělili podle daných kritérií z kvantitativního hlediska. V kvalitativní analýze jsme se snažili najít modelové situace nejčastějších vstřelených branek a popsat je jak z obranného tak i útočného pohledu. Výsledky: Výsledkem jsou grafické znázornění všech vstřelených branek v české nejvyšší fotbalové lize v ročníku 2010/2011 a porovnání výsledku s výsledky z vrcholným soutěží světového fotbalu. Dalším výsledkem je nalezení nejčastěji se objevujících modelů útoku při úspěšném zakončení vstřelenou brankou a jejich popis z útočného a obranného pohledu. Klíčová slova: fotbal, vstřelené branky, typologie střelby, herní systémy
