Online Tool for Monitoring and Processing of Searching Engine Results
Sedlář, Petr ; Samek, Jan (referee) ; Martínek, Zdeněk (advisor)
The aim of this work was to design and implement the application that is easily, quickly and effectively able to determine the position in the www search engines based on the given World Wide Web pages and theirs key words. The application is accessible by the web interface and it enables comparison of the position statements from the archives, comparison of the graph outputs, as well as sending of PDF format files containing regular results statements. Together with the position it is stored the number of references of particular word in the search engine. Furthermore, it is possible to display also the position changes compared with the former statements. As stated above, it is possible to store the outputs in the PDF format documents and therefore it is easy to shore the entire development in your personal computer, in case online system is insufficient.
Digital controlled resistor
Sedlář, Petr ; Petržela, Jiří (referee) ; Šotner, Roman (advisor)
This master´s thesis deals with the design of the control circuits for digital potentiometers and their application in analog systems. Digital potentiometers are three-terminal resistors with an adjustable center connection. The digital potentiomneters enable to drive logic gates, LED drivers, LCD drivers, analog switches etc. Controlling of these mentioned devices is possible by the I2C 2- wire serial bus (invented by Philips). The digital potentiometers are used to control of the primary parameters like cut-off frequency and quality factor in the state variable filter and cut-off frequency in a passive filter. Both filters are simulated in PSpice and then compared with the measured results. Next parts of this master's thesis are a computer program and a exemplary protocol.
Network Protection Using NetFlow Data
Sedlář, Petr ; Žádník, Martin (referee) ; Tobola, Jiří (advisor)
This document provides information about Cisco NetFlow technology and its usage to protect networks from different types of attacks. Part of the document is a summary of common security risks in term of their detection on network and transport layer. There are specified characteristics of NetFlow data containing samples of security risks. On the basis of these characteristics, an application for detection these risks is designed and implemented.
Change of magnetic susceptibility during the germination of plants
Sedlář, Petr ; Fiala, Pavel (referee) ; Vlachová Hutová, Eliška (advisor)
The work examines the changes in the magnetic susceptibility during the early germination of the somatic embryo (RSE) of the Norway spruce. Susceptibility is in the physically view the property, which can be used to determine a variety of parameters and properties of the measured objects. The aim of this work was to create a automatic to evaluate the susceptibility of the tissue RSE and take measurements to prove or disprove the contrary of the accuracy of this assessment. This work contains the results obtained by modeling a script in Matlab, in which can be shown the correctness of the theoretical concepts.
Design and Realization of the Bird Cage Coil for MRI
Sedlář, Petr ; Drexler, Petr (referee) ; Nešpor, Dušan (advisor)
The work deals with the design and experimental production of the model type Birdcage coil used for magnetic resonance imaging system (MRI). The work deals with the design and behaviour of the model type Birdcage coil volume designed for imaging system for magnetic resonance imaging (MRI). Volume coils are generally very useful for use in MRI, because in transversal design allow easy access into the cavity when the flow vector of magnetization. The aim of the work was to construct a numerical model of transversal coil type Birdcage of the predefined dimensions. The created the coil tuned the desired resonant frequency having regard to maximize performance in the measured sample migrated. The modeling coil experimentally produced and measurements also confirm the accuracy of the numerical model.
