System for Programming Minerva Platform
Dohnal, Michal ; Strnadel, Josef (referee) ; Bidlo, Michal (advisor)
Theoretical part of this thesis studies several concepts and interfaces being used for programming microcontrollers (MCUs) and reconfiguration of field programmable gate arrays (FPGAs) with closer look at those, which are available for MCU Kinetis K60 and FPGA Spartan-6 in circuitry given by the architecture of educational kit Minerva. This knowledge is employed in practical section which describes deployment of the supporting firmware belonging to group of firmwares so-called bootloaders. Finally the application QDevKit3 is introduced, that is based on this firmware, representing effective and fast way for easy programming of FLASH memory on Kinetis MCU using USB interface.

Laboratory model of a technological process
Macej, Maroš ; Pásek, Jan (referee) ; Zezulka, František (advisor)
In this thesis, there is implementation of the closed circuit mill model in the program Control Web. The model contains both logical and dynamical elements. There are four systems in the model. Three systems of the firsth degree are regulated by PI - controller, the fourth is regulated by a PSD - controller. The regulators were designed in the program Matlab using sisotool and simulink.

Router principles illustrating software for teaching support
Sobek, Jiří ; Vymazal, Michal (referee) ; Vychodil, Petr (advisor)
This bachelor thesis is mainly focused on the network functionality and its key component, the router. The main points of this work are an explanation of the network principles and router functions which are extended with information about routing protocols and its mutual separation. The practical part considers a realization of applets which should serve as a school software. In detail they explain the way of routing protocols work and its inner structure. Simultaneously consider the principles of two significant routing protocols such as Open Shortest Path First (OSPF) and Routing Information Protocol (RIP). All of the applets are finally loaded on the web page which helps to their visitors understand the complexity of routing and other infomation.

Signal Processing in Flarion System
Szajkó, Juraj ; Kejík, Petr (referee) ; Hanus, Stanislav (advisor)
Cílem bakalářské práce Zpracování signálů v systému Flarion bylo prostudovat způsoby zpracování signálu ve fyzické vrstvě a architekturu sítě Flarion. Na základě získaných poznatků při studiu fyzické vrstvy bylo za úkolem sestavit v prostředí Matlab model systému a simulace BER v závislosti na poměr vysílaného výkonu a výkonu rušivého signálu. V první části práce je detailní popis fyzické vrstvy Flarionu, probrána je baseband a OFDM modulace, LDPC kódování a frekvenční skákání. V druhém části práce je prostudována architektura sítě, ekvalizace, řízení výkonu, radiových zdrojů, a způsob handoffu. Ve třetí části práce je vytvoření downlink a uplink modelu v Matlab, dále je provedena simulace BER v závislosti na poměr vysílaného výkonu a výkonu rušivého signálu.

MRI Acquisition of Image Sequences for Preclinical Perfusion Imaging
Krátká, Lucie ; Bartoš, Michal (referee) ; Jiřík, Radovan (advisor)
The task of this thesis is to study methods for the acquisition perfusní imaging based on dynamic MR imaging with T1 contrast. It describes methods of measurement of T1 relaxation time and the possibility of evaluating the results. It further describes the phantoms and their use. And it is here mentioned for the dynamic acquisition protocol perfusní imaging. There is also described in detail created a program for automatic control of the NMR system. In the experimental measurements are performed on static and dynamic phantom, are also evaluated perfusion parameters from the Flash sequence.

MRI Acquisition and Preprocessing of Image Sequences for Clinical Perfusion Imaging
Krchňavý, Jan ; Bartoš, Michal (referee) ; Jiřík, Radovan (advisor)
This thesis describes the theory for static and dynamic magnetic-resonance imaging using contrast agents affecting T1 relaxation time. The available acquisition methods in the specified facility of Masaryk Oncological Institute in Brno are described. The sequences for subsequent experimental measurements are selected. The used phantoms are described. Acquisition protocol for measuring is described briefly and the evaluation method for the measured data is suggested. The best acquisition sequence and a method of measurements is chosen influenced by estimation of relaxation time T1, sensitivity and signal to noise ratio. Perfusion analysis is executed and perfusion parameters are calculated. The work was supported by the European Regional Development Fund and the State Budget of the Czech Republic (RECAMO, CZ.1.05/2.1.00/03.0101).

Software design support of burglar alarm system
Vymazal, Michal ; Pelka, Tomáš (referee) ; Burda, Karel (advisor)
This thesis deals with implementation of software support of alarm system design for security levels 1 and 2 based on web technologies. It was created intuitive and interactive graphical interface that allows to create high-quality alarm system design even for laymen. First of all the paper deals with standards and jurisdictions in the Czech Republic, according to which the alarm system design must be followed. In theoretical part there are described in detail characteristics of alarm systems and its components, proper functioning principles, installation principle, advantages and disadvantages of use, individual steps of alarm system design and proposed methodology of alarm system design for security level 1 and 2. In practical part there are described the technologies used for the implementation of this paper, structure of created webpage and detailed steps of alarm system design, as seen by user during creating. The result of this paper is a webpage, which is divided into two parts: theoretical and practical. The theoretical part provides information about the alarm system architecture, alarm system design and established methodology for the alarm system design for security level 1 and 2. In the practical part the user, on the basis of gained information and interactive help, can create high-quality alarm system design that meets all the conditions for reliable function in real traffic.

Simplified model of a axial cooled arc
Kasal, Ondřej ; Šenk, Josef (referee) ; Lázničková, Ilona (advisor)
Using of computer technology brings advantages of quick and well-arrange data. Computer technology offers change of transferring information the same way as that often using. Capacity and execution of computer technology is depending on kind and size of elaborated information. It is necessary to use to computer technology in application working with big data range and in application which needs many steps to finish calculation it means when we are using iterative methods. It is computer technology which creates main part of simulation, computation and visualization methods which are using in technical application. Plasma is using in many way of industry from technical manufacturing of materials to application in power electronics. Attention is paid to plasma. To description to fourth state of substance and for description to processes in plasma are used mathematic and physic equations. To solve to equations is hard and we need many steps to cover it. It is necessary to use computer technology to work up different method performs to describe electric arc.
