Biometric system for retina and iris recognition
Hájek, Josef ; Derawi, Mohammad (referee) ; Provazník, Ivo (referee) ; Drahanský, Martin (advisor)
Tato disertační práce se zabývá biometrickým a medicínským zařízením pro simultánní snímání duhovky a sítnice oka v jednom kroku. V případě biometrického zaměření je práce rozšířena o vzájemnou fúzi těchto dvou biometrik do jedné šablony, kdy multimodální systém vykazuje mnohem lepší parametry než systém unimodální, a to především ve větší unikátnosti, univerzálnosti a velmi obtížně proveditelnému útoku (až téměř nemožnému) na senzor. V případě medicínského využití práce dále rozvíjí detekci a klasifikaci nemocí pro základ expertního systému pro oftalmologické účely, který bude umožňovat pomoc lékaři při stanovení diagnózy nálezu v obrazu sítnice (či duhovky) oka.
Application for Mikrotik RouterOS Remote Management
Doležal, Jiří ; Novotný, Tomáš (referee) ; Hájek, Josef (advisor)
This bachelor´s thesis deals with design and implementation of an application for remote management MikroTik RouterOS. Within this thesis has been created an application which allows to configure network router services. The thesis contains design and implementation of an application written in programming language C#. The application is runnable under operation systems MS Windows and Linux by using framework Mono. The application uses a user friendly graphical interface for simple management devices with MikroTik RouterOS.
Wireless Voting System
Slezák, David ; Hájek, Josef (referee) ; Korček, Pavol (advisor)
This thesis deals with designing and implementation of wireless voting system based on the IQRF technology. The thesis describes mentioned IQRF technology and compares its features with others wireless technologies. It also describes the architecture design and communication protocol of the proposed system. The system consists of device conected to computer which collects data from the voting stations. The core of the thesis is the implementation of this components and implementation of control application for the computer. In conclusion, discussed the achievements and possible improvements.
Management of UPS Supplies with GSM Technology
Hájek, Josef ; Slaný, Karel (referee) ; Šimek, Václav (advisor)
Theme of the Master's thesis is issue of backup power units and its attributes. There is also complete proposal of UPS power unit which can be used to control and monitor backup batteries. Power supply is fully controlled via Ethernet interface using TCI/IP protocol. The other chapter describes complete development of TCI/IP GSM unit which can be used for communication interface between GSM and Ethernet protocol. UPS and GSM modules are developed in details. The Master.s thesis includes all needed information for HW unit development and also for controlling software as well. Universal solution of the modules allows number possibilities of further development.
Ethernet to RS-232 Converter
Dreiseitel, Jiří ; Novotný, Tomáš (referee) ; Hájek, Josef (advisor)
The thesis deals with construction of a convertor between Ethernet a RS-232 serial interface using a single-chip microcontroller. The aim is to make the reader acquainted with the technology of an Ethernet network and serial transfer based on RS-232 protocol. The embedded systems for the convertor construction are also explained. The thesis contains a complete design of Ethernet to RS-232 convertor including firmware analysis and implementation in C language using LwIP TCP/IP stack. The convertor has been built on STM3210C-eval development kit, equipped with STM32 family microcontroller. The conclusion describes testing in model situations and recommended usage.
Development of Platform for Three-Rotor Helicopter
Votava, Martin ; Rozman, Jaroslav (referee) ; Hájek, Josef (advisor)
The goal of this master's thesis is design and built of platform for three-rotor helicopter development. The helicopter is also known as tricopter. Theoretical part describes principle of tricopter's flight and stabilization. There is also described basics inertial navigation system and sensors which are required for correct functionality. Practical part is dedicated to development of tricopter's frame, schematics diagram, communication between subsystems and stabilization system development. Flight stablization system is base on ATmega128A an using PID Controller. In the end is described testing of developed platform.
Implementation of Algorithm for Recognition of Eye Retina
Ondroušek, Jan ; Stružka, Jaroslav (referee) ; Hájek, Josef (advisor)
Vessel structure is a very important element in medical sience for diagnosis of eye and cardiovascular diseases. Therefore, its automatic segmentation is very important too. In introduction there is a short description of eye retina. After that, method of implementation is presented according to Ing. Jan Odstrčilík's thesis - Analyze of colour retinal images aimed to segmentation of vessel structures created under the auspices of Brno University of Technology - Faculty of Electrical Engineering and Communication, Department of Biomedical Engineering in 2008. This method is based on filtering input image with properly designed filtering masks, followed by thresholding with properly calculated value and finally cleaning result image from artefacts. Algorithm was written in C++ language. All important functions were implemented for purpose of given method with consideration on speed and accuray. Main sections of source code with description of user interface are introduced next in this thesis. At the end, the implementation was tested on real images from ÚBMI and DRIVE databases, results were recorded, expansions and adjustments possibilities of implementation were debated.
Guard System for Household with Usage of GSM Communication
Křesal, Tomáš ; Drahanský, Martin (referee) ; Hájek, Josef (advisor)
Theme of the Bachelor's thesis is the issue of security of households. Discusses the current methods of protection, of their typical characteristics and shortcomings. Based on information gathered from the opening chapters is designed and engineered an electronic security device with alarm transmission to the mobile phone. Remote control of electrical appliances and supervision households via the Internet extends the applicability of the system. The conclusion of this work is devoted to the hardware implementation of the proposed security system. Software implementation is not discussed here and will be part of further development.
Extension of Intelligent Home by Thermoregulation Control
Köszegy, Lukáš ; Hájek, Josef (referee) ; Viktorin, Jan (advisor)
This bachelor thesis is focused on the integration of the heat regulator VPT made by the company Thermona into the system for intelligent home control called BeeeOn. In the theoretical part, the most specific components of BeeeOn system and heat regulator VPT are described. The most important part of this thesis consists of the design and implementation. It focuses on gather values measured by the VPT regulator by means of the HTTP protocol. The measured values are provided in a separate JSON data file. In these parts there are also described the necessary elements, which have to be integrated into the BeeeOn system and VPT regulator.
Electronic Platform of the System for Eye Retina Acquirement
Malaník, Petr ; Hájek, Josef (referee) ; Drahanský, Martin (advisor)
This work deals with a control of the platform which is used for scanning of the eye retina. The purpose of this platform is the three-axis motion, camera sharpening and a controlling of LEDs to illuminate the eye. Within this is solved the issue of stepper motor control, LED brightness control and communication with a microcontroller. Part of the thesis is the programming of STM32, i.e. 32-bit microcontroller of STMicroelectronics in C/C ++ using HAL abstraction layer and Python 3 demo application.
