Design of the electrochemical detector for detection of heavy metals
Sedláková, Jana ; Jelenčík, Branislav (referee) ; Škaroupka, David (advisor)
The topic of this master’s thesis is design of detector for electrochemical detection of heavy metals. Design meets the technical, aesthetic and ergonomic requirements and is developed in collaboration with other members of the research team involved in the grant project TACR named DETEKO TH01030389.
Detection of ionize radiation with Geiger-Müller tube
Dědina, Radim ; Macků, Jan (referee) ; Musil, Vladislav (advisor)
This work deals with problems related with detection and measuring of the ionisated radiation. First part of this work is devoted to theoretical problems of detection, particulary to measuring with Geiger Muller tubes. Second part of the work contains proposal of electronical circuit using Geiger Muller tube as well as description of results experimentally acquired while using the detector, which was manufactured according to the proposed scheme. On the basis of those results it appears that proposed apparatus can be used for significant indication range extension.
Spectrum sensing implementation in FPGA
Maňas, Ondřej ; Povalač, Karel (referee) ; Maršálek, Roman (advisor)
The aim of this thesis is a software modelling and hardware implementation of spectral sensing algorithm based on cyclostationary based detection. A proposed detector is fully implemented in FPGA and further tested under measurements in real RF environment.
Security Conception of Brno Turany Airport
Loučka, Karel ; Sedláček, Jaromír (referee) ; Janík, Radomír (advisor)
In my thesis I address improvement of safety system of an international airport in Brno-Turany. I perform an analysis of current legislative safety needs and description of EU airport issues. I define particular safety requirements in reference to Brno-Turany airport. In the last part of my paper I suggest safety system that takes advantage of up to date technologies and recommendation to secure safety.
GSM alarm for motorcycles
Beníček, Martin ; Fedra, Zbyněk (referee) ; Urban, Josef (advisor)
The main target of this work is to design and to implement unfailable safety appliance for motocycles with use any GSM technology. In my masters’s thesis I applied to individaul fields which I had to knows for realization of this work. The introductory chapter tells the reader about evaluation of former semestral projects and about brief description of the realized mechanism. It is followed by descripctoin of principles of communication between PC and mobile phone. The main part of my work is dedicated to application itself. The applicaton is called motoalarm. The last chapter creates description service of localisation mobil phones which is called Kde je... The conclusion includes evaluation of this master´s project and general description of the realized mechanism.
Indikator position behind the wall
Pecha, Václav ; Marcoň, Petr (referee) ; Szabó, Zoltán (advisor)
The work sums up the basic measurement principles for different kinds of searching devises. It deals with measurement using resonance. The feature of resonance and measurement techniques are described to set the location of the radiating circuite. The work contains the design of a locator of position behind a wall itself as well as the concrete switch connection, schema and description of receiver and emitter in the circuit.
Fluctuations and noises analysis in free space optics
Pokorný, Aleš ; Křivák, Petr (referee) ; Hudcová, Lucie (advisor)
This project is directed at fluctuations and noises analysis in free space optics. These distorting effects go with laser beam propagation through random media. The next assignment is to project method to measure them. Finally project is to make a measurement to acknowledge accuracy this method.
BER Meter for Video Signals
Šimoník, Petr ; Frýza, Tomáš (referee) ; Říčný, Václav (advisor)
The diplomma thesis is dealing with possibilities of Signal to noise ratio measurement by method, which is based on direct measurement. It is chosen the most suitable method – signal and noise separation to two different parallel signal branches, where is measured signal strength in one branch and root mean square value in the other. The thesis is consisted of a concept of detail block scheme of Signal to noise ratio meter, which was designed in terms of theoretical knowledge. Particular functional blocks were circuit-designed, the active and passive parts were chosen and their function were described. There were made simulation and displayed input and output time flows. There is designed the whole connection of engineered Signal to noise ratio meter in the last part of my thesis. The double-sided board of printed circuit is contained too. It was created simple programme for supervisor micro-processor. Thereby were constructed complete bases for realization.
Security System Using FITkit Platform
Macek, Miroslav ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The first part of this thesis describes the principles of detectors and other components used in electronic security systems. Then presents a general design of the new security system, followed by detailed design and description of the hardware. Finally, the thesis describes the software implementation of all the modules of the system.
Automatic measurement of the motor vehicles distance.
Juřica, Lukáš ; Chmelař, Milan (referee) ; Říčný, Václav (advisor)
This work deals with evaluation of equipment used for non-contact measurement of distance between vehicles. First are discussed various principles of measuring and after the selection of the most appropriate solution is proposed a detailed block diagram of modulation, demodulation and evaluation of the whole system and its mathematical description. Another part is devoted to describing the activities of the microprocessor controller, with which is controlled evaluation part and to the control program. It also analyzes the maximal attainable accuracy of measurement and the errors that affect it. The last part includes a circuit design and simulation of selected functional block, which is a coincidence /quadrature/ detector and construction documents for evaluation and demodulation part of the measurement instrument.
