Modular linear axis
Chlapečka, Tomáš ; Bilík, Martin (referee) ; Pavlík, Jan (advisor)
This thesis contains a structural design of linear axis with a stroke up to 800mm and a maximum load of 800N. The thesis also deals with a modular assembly system of the linear axis based on the structural design. Linear axes can be fitted with rolled, whirled and grinded ball screws with thread pitch 5, 10, 16mm and rolled trapezoidal screws on pitch 4 and 8mm. The stroke of the linear axes can be selected in the range from 200 up to 800 mm, with a maximum load of 800N in all linear dimensions. The feed of linear axis is provided by shaped rolling guide way and four trucks. The modular system offers two servo motors with direct and indirect measuring four stepper engines with indirect measuring. The thesis also includes strength and functional calculations of principal components, graphs of the possible load on linear axis in different positions , durability of the ball screws, maximum speed and feed rate of the chosen screws, data sheet, 3D model, drawings and assembly drawings of the nodes.

Wireless modular system for device control and data acquisition
Pejchal, Luboš ; Tošovský, Petr (referee) ; Kubíček, Michal (advisor)
The aim of this project is to design a cheap and simple modular wireless system. Its purpose is wireless control of remote devices and transmission of short information blocks (temperature data, status of controlled devices…). The whole system is controlled by a PC. It utilizes hybrid wireless modules for transmission of information and control of remote devices. The project shows practical usage of a digital thermometer communicating via a 1-Wire bus. A solar cell in conjunction with a DC/DC up converter is used to power low-power temperature sensor device.

Deploying Virtual Servers for ISP
Zelený, Jan ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
This thesis describes principals of virtualization based on the Xen project. Text focuses mainly on putting system into service for purpose of it's subsequent use by ISPs. The goal of this work is also to explore the possible usages of virtualized systems based on the Xen by ISPs. One of these possibilities will be specified to the point when it will by usable or it will be able to be developed independently of author of this work. This work also designs and mostly implements system, which can be used as a base for wide spectrum of of services, when installing these services doesn't effect the rest of the system.

ARM Cortex M4 Development board
Volek, Lukáš ; Macho, Tomáš (referee) ; Burian, František (advisor)
In this work I aimed at designing a universal system for testing either STM32F407/417 by STMicroelectronics and later various sensors and communication buses. The result then is a main board with many specific connectors for individual buses even with connectors making all I/O pins accessible at the same time. Thanks to advanced switching regulators the power supply is capable of accepting a wide range of sources like single Li-Ion cell, pair of alkaline cells, 12V Lead battery, common wall power adapters (both DC and AC up to 15 Vpp ), USB, laboratory power supplies with multiple outputs and finally POE (Power Over Ethernet). Supply voltages are supervised by voltage comparators with an optical signalisation. (It is possible to determine the sick branch without a measuring instrument and blowing components in the most cases.) Another important parameter was a robustness of the supply and communication lines. There is a number of TVSs, chokes, and big and low ESR capacitors A PC software is intended for a basic functionality demonstration only.

Graphical User Interface in JavaFX
Fusek, Zdeněk ; Nagy, Ľuboš (referee) ; Karásek, Jan (advisor)
The aim of of this thesis is creation of the simple computing system. In the first part will be processed research, which involves comparison of RIA platforms. The result of research is the analysis of advantages and disadvantages of each platform. Due to orientation of the thesis, JavaFX platform will be described in detail in a separate chapter. For creating the application, which is presented as a simple computing system, is necessary create modular kernel at first, then propose a user interface, which prescribes the basic look of the application. Subsequently is created function drag & drop. Modules of arithmetic operations and their input will be transmitted by using this function. Calculation of the result is possible after connecting inputs with the arithmetic operations. Creation of computing system is described in detail in the practical part of thesis. Bachelor thesis is implemented in a development environment e(fx)clipse, and CSS Cascading Style Sheets are used for the styling of thesis.

DCS for building control
Kopeček, Petr ; Beran, Jan (referee) ; Bradáč, Zdeněk (advisor)
This thesis deals with DCS for bulding control. The main aim was to develop a general system, which can be adapted according to the individual requirements and which should minimize costs too. Hardware modules, communication bus, communication protocol, system topology and regulation mechanisms, have been designed. Regulators have been set. There are introduced current realization and possible future extensions too. The high security and the high functionality topics are included.

Design and implementation of a wireless transmission system using USRP
Vaclík, Michal ; Mlýnek, Petr (referee) ; Krajsa, Ondřej (advisor)
This thesis is focused on design and possibilities of implementation of modular wireless communications system based on software defined radio. This system uses USRP1 kits from Ettus Research and is controlled by GNU Radio Companion software. Final Python script is used to controll and modify parameters of modulation schemes, encoder properties and used bitrate. Thesis also describes possibilities and challenges of using radio HW for transmitting and receiving. Final chapter summerizes and analyzes achieved transmission qualities.

Easily Upgradable Graph Editor
Sysel, František ; Martinek, David (referee) ; Smrčka, Aleš (advisor)
The bachelors thesis deals with design and implementation of graph editor. The emphasis is put on division of the whole application into independent plug-ins which can be replaced by other plug-ins or extended with new plug-ins and thus to add its functionality. Theoretical part deals with techniques for development of module applications while practical part describes design and implementation of particular plug-in modules of a program. The thesis also contains automatic tests for module development.
