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.

Doppler blood flow indicator
Böhm, Richard ; Bubník, Karel (referee) ; Rozman, Jiří (advisor)
This bachelor‘s thesis deals with literature search of basis of ultrasonic and Doppler methods of measuring blood flow velocity. It also deals with the evaluation of Doppler signals and with the individual functional system blocks, with the indicator of blood flow with the operating frequency of 4 MHz, with the generated ultrasonic intensity of 100 mW/cm2 and with the average transmitting changer in shape of D = 8 mm. Furthermore, experimental verification of individual system components is included.

The Hidden Resources Detector for GNU/Linux
Nečas, Radek ; Rogalewicz, Adam (referee) ; Procházka, Boris (advisor)
The main goal of this thesis was to detect hide resources in GNU/Linux operating systems and analyse tools so called rootkits, which are used to hide system resources. This thesis is devided into two parts, theoretical and practical one. Theoretic part focusses on resource managment, representation, privilege levels and system calls. Practical part covers design and implementation of an abstract detector. Each new detection method is implemented as a plugin. Some of those methods are realized as linux kernel modules. The usability of the detector is compared against real rootkits.

Simulation and measurement of neutron field by Bonner spheres
Arbeit, Vít ; Šťastný, Ondřej (referee) ; Mičian, Peter (advisor)
The objective of this master’s thesis is introduction, explanation and practical demonstration of simulations conducted in program PHITS. The first part analyses neutrons and related issues regarding their detection as well as neutron sources. Next part is focused on program PHITS, both on it’s basic and advanced functions. Practical part of this thesis deals with the simulations of Bonner spheres and their responses to neutrons of different energies under different conditions. It also compares the results obtained through simulations with measured data.

Comparison of the imaging capabilities of the transmission and scanning electron microscope
Maňka, Tadeáš ; Šamořil, Tomáš (referee) ; Zlámal, Jakub (advisor)
The aim of this work is to compare the imaging capabilities of the transmission and scanning electron microscope. The theoretical part describes the construction and the principle of each type of microscope. There is a list of the signal detectors, and the principle of imaging is described. The samples and their preparation are described. The practical part is aimed to imaging possibilities of both microscopes. A standard calibration samples were used for comparison. The advantages and disadvantages of both microscopes were discussed.

Wavelet transform-based QRS complex detector
Nagyová, Lenka ; Vítek, Martin (referee) ; Smital, Lukáš (advisor)
This work aims to solve problems of ECG signal, or QRS complex and its detection. For understanding the activity of the heart and ECG it is necessary to describe the anatomy of the heart and all processes that are at the heart. Next part of the work is dedicated to the detection of the QRS complex. The greatest attention has the wavelet transform, which will be used in the implementation of the detector. This paper focuses on the following issues: the construction of the detector, options, use of the transform in Matlab. In the end, the results of this work, are evaluated.

Removal of Anesthesia Tube from Pediatric CT Data
Šejnohová, Marie ; Čmiel, Vratislav (referee) ; Walek, Petr (advisor)
The goal of this semestral thesis is to detect and subsequently to eliminate an anaesthesiological tube from a pediatric CT data using a Hough transform. It describes particular edge detectors based on the first and the second differences. In addition, it explains a principle of the edge detection using to this detectors. Then there is talked about the Hough Transform where is described a parametric space for lines and circles detection. Here follows a description of image to the parametric space. In a practical part there is implementation of the edge detection and the Hough transform. The Hough space must be normalized to better evaluation. At the evaluation there are found a concentric cicrles corresponding with edges of an anaesthesiological tube which is then possible to remove.

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).

Security System Management of the Company
Moravec, Lukáš ; Hajný, Jiří (referee) ; Ondrák, Viktor (advisor)
This master thesis deals with the design of complex security system for company area with using PZTS and CCTV system. The thesis is divided into three separate parts, first part is focused on analysis the company and the current physical security state. Second part of thesis deals with theoretical bases. And the final part covers the concept of the PZTS and CCTV system solution. Here are all the chosen elements which will be used for realization
