Microprocessor controled security system for house or flat.
Kozák, Matěj ; Petyovský, Petr (referee) ; Macho, Tomáš (advisor)
This thesis deals with security systems used in houses or flats. It contains descriptions and principles of most sensors for detecting a thief, but also protect the dwelling against fire. It explained the selection of appropriate solutions and sensor control unit described the proposal for the evaluation of information from sensors and communicate with computer.

A Proposal for a Security System of the Company Premises
Černý, Jan ; Sedlák, Petr (referee) ; Ondrák, Viktor (advisor)
The content of this thesis is the complex security system proposal, specifically of PZTS system and CCTV system. The thesis is divided into three parts. The first part is analysis of the current state, the second is theoretical part and the third part is a practical part. The first part deals with the analysis of the current state of physical security and technical protection of the premises. The theoretical part deals with theoretical solutions for security system proposal. The practical part is focused on separate PZTS and CCTV systems proposal, that will meet all the requirements and standards of the customer.

Measurement of optic detector properties
Smrž, Martin ; Harabiš, Vratislav (referee) ; Odstrčilík, Jan (advisor)
Purpose of this master thesis is get acquainted with laboratory components designated for measurment of optical detectors, study principials of function of each detector and learn how to work with measuring machines. On the base of this knowledge will be measured spectral, frequency and dynamic characteristics of each detectors. The outcome of the thesis will draft of the laboratory exercise for subject Microscopy imaging technique teaching at the first semestr of follow-up masters studies of Biomedical engineering and bioinformatics at DBME, FEEC, Brno University of technology.

QRS detection based on wavelet transform
Zedníček, Vlastimil ; Ronzhina, Marina (referee) ; Smital, Lukáš (advisor)
This thesis deals with implementation of detector QRS complex with use of wavelet transform. The first part is focused on formation and possibility to measure cardiac activity. The other part of thesis we will familiarise with the different possibilities of detection QRS complex and we intimately focus on wavelet transform that will be used for a project of detection QRS complex. The practical part of thesis focuses on the project of detector in programming language Matlab and his different setting. This projected detector has been tested with CSE database. Achieved results of projected detector are evaluated with the results of others authors.

Digital Signal Processor based Baby Cry Detector
Sobotková, Šárka ; Rozman, Jiří (referee) ; Sekora, Jiří (advisor)
The thesis discusses the baby cry. Processing of literary research in dealing with children crying and processing of audio signals. Based on information gathered propose an algorithm for detecting child's cry, which was verified using Matlab programming environment. Based on the identified parameters of the input signals and the proposed algorithms was selected appropriate digital signal processor. The hardware device was realized to detect and initialize the child crying, and its functionality has been verified in the recorded sound recordings child crying.

Facial features recognition of unknown persons
Bartončík, Michal ; Babinec, Tomáš (referee) ; Horák, Karel (advisor)
This paper describes the various components and phases of the search and recognition of facial expressions of unknown persons. They are presented here as well as possible solutions and methods of addressing each phase of the project. My master’s thesis is designed to recognize facial expressions of unknown persons. For this thesis, I was lent industrial video camera, computer, and place in a laboratory. Furthermore, we introduce the color spaces and their use. From the lead representatives selects the most appropriate assistance for the use of Matlab and the proposed algorithm. After finding a suitable color space segments skin color in the image. The skin, however, surrounds the entire body and so need to be found, the separated parts of the image representing the color of skin, a face. Once you find a face is needed to find relevant points for the identification subsequent deformation to definition of facial expressions. We define here the actual muscle movements in different expressions.

Project of comprehensive security objects
Michálek, Libor ; Burda, Karel (referee) ; Herman, Ivo (advisor)
In my thesis I go about principles and methods of security systems, then I go about analysis of avalaible types of security systems (EPS, EZS and CCTV). I have written about their possibile use in design security building. I have described levels of project documentation and its different parts including process service of production a project documentation for security system. I used all knowledges in the end of my thesis, when I designed and integrated security system for a special building.

Using Cosmos FloWorks for analyse the detector.
Bordovský, Petr ; Špinka, Jiří (referee) ; Maxa, Jiří (advisor)
This work deal with the analysis of influence of pressure‘s sizes in vacuum chamber of specimen Evironmental Scanning Electron Microscope and the influence of sizes of aperture diaphragm by scintillation detector. The analysis proceeds in detector of secondary electrons. The detector is modelled by system 3D CAD SolidWorks with the help of system CAE Cosmos FloWorks.

QRS detection in ECG signals
Kuna, Zdeněk ; Vítek, Martin (referee) ; Kozumplík, Jiří (advisor)
This project considers methods of construction QRS detectors. It focus in detection complexes of QRS single leads and space speed, which are calculated from three orthogonal leads. In theory was refer to various methods, which lead to design detector. It were designed two algoritms (constant and adaptive detecting threshold), which were implemented into detector and the signal was preprocessed by Hilbert transformation. Toward algoritms were completed by modification, which improved detection effectivity. Function of algoritms were tested in all signals of CSE (V2,V5,aVF).
