Hladík, René ; Zuth, Daniel (referee) ; Věchet, Stanislav (advisor)
This bachelor’s thesis obtains a kind and possibility of communication, which single board computer offers. Check range of communications using mobile robotics and summary for this system. The result of this work provides a configuration all peripherals for Beagleboard system using. The introductory part of work is focuses on the definition and summary single board computer systems. Description main differences single board systems. Next point is competition and summary single board computers from the world's leading manufacturers and hardware differences. The next part is making complete description and summary of using single board computer Beagleboard xm Rev C. Practical realization obtains the most important interface of communication, which we can use in case of prototypes mobile systems. Realization of USB camera, multifunctional interface GPIO, serial communication of CMUcam3 camera module and in conclusion I2C communication using GPIO SRF08 ultrasonic sensor. Demonstration of Beagleboard system diversity, what can use all users of embedding systems in mobile robotics. Modern mobile robotics systems are complex analog and digital devices like different kind of sensors, sensing elements, cams and else. Bachelor work describe basic configuration some possibility communication with using cameras, sensors and systems elements.

Use of FRP Composites as Reinforcing Material for Concrete
Kratochvílová, Denisa ; Prokeš,, Jan (referee) ; Bodnárová, Lenka (advisor)
Because FRP composites have high fiber strength and good durability, they are increasingly used for repairs, modernisation and reconstruction of concrete structures. In practice, however there is a risk of premature separation of FRP reinforcement from concrete. This can be avoided by appropriate selecting the fibers and the matrix and the appropriate shape of the reinforcement. The actual materials and consistency of FRP reinforcement with concrete are also covered by this diploma thesis.

User-Friendly Animated Communication with OLAP System
Kupčík, Jaroslav ; Šuška, Boris (referee) ; Hruška, Tomáš (advisor)
Complexity of multidimensional data models and its usage does not have positive influence on quality of user-friendliness of application working with them. The option of solution of negative influence of this fact on laic end-user is usage of visualisation technics for upgrade of user interface of the system. Nowadays there are powerful tools usable for impressive manipulation of originally static document on the client side. By using them, interface of the system can be enhanced with an interactive help. Usability of this modul has to satisfy maximal portability requirements. Important aspect is also range and methods of configurability of result of practical part of thesis.

Component Interconnection Inference
Olšarová, Nela ; Rychlý, Marek (referee) ; Křivka, Zbyněk (advisor)
The Master Thesis deals with the design of hardware component interconnection inference algorithm that is supposed to be used in the FPGA schema editor that was integrated into educational integrated development environment VLAM IDE. The aim of the algorithm is to support user by finding an optimal interconnection of two given components. The editor and the development environment are implemented as an Eclipse plugin using GMF framework. A brief description of this technologies and the embedded systems design are followed by the design of the inference algorithm. This problem is a topic of combinatorial optimization, related to the bipartite matching and assignment problem. After this, the implementation of the algorithm is described, followed by tests and a summary of achieved results.

Surface modification of glass fibers for polymer composites
Knob, Antonín ; Marek,, Aleš (referee) ; Burša, Jiří (referee) ; Čech, Vladimír (advisor)
The doctoral thesis is aimed at preparation of glass fiber reinforced polymer composites with controlled interphase formed by plasma-polymerized tetravinylsilane and tetravinylsilane/oxygen thin films. The thin polymer films of specific physico-chemical properties and thickness were deposited to improve interfacial adhesion of glass fiber/polyester composites. The fiber surface modification was performed by using plasma enhanced chemical vapor deposition in low-temperature RF plasma operating in an various effective power range and different treatment time. Test results were examined in relation to the interlayer thickness and different treatment conditions. The prepared interlayers were analyzed to evaluate physico-chemical composition and properties (XPS, RBS, ERDA, FTIR and spectroscopic elipsometry). Selected mechanical properties were evaluated by AFM. Mechanical response of plasma interlayers was evaluated by short beam shear test and direct method of testing the interfacial shear strength using microindentation. The interphase shear failure was controlled by the shear strength at the interlayer/fiber interface as follows from experimental and model data.

Interfaces of Web-Services
Kubát, David ; Rychlý, Marek (referee) ; Weiss, Petr (advisor)
The objective of this thesis was to get acquainted with the proposition of the service-oriented architecture and its real representation web services. To understand the principles of their functioning, creation, communication and the ways to finding and using them. To be specific, the goal of this project was to analyse a current program, design its transfer to the web service description language and to implement a web service interface layer upon this program. The system is demonstrating the basic principles of the web services and the function of the interface during the communication between its provider and customer.
