Technical and economic comparison of usability of different types of cements
Kováč, Michal ; Ťažký, Tomáš (referee) ; Hela, Rudolf (advisor)
This bachelor thesis deals with comparison of properties of different types of cements. The theoretical part is devoted to the distribution of cements, their composition and production. Various properties of cements are detected and compared in the practical part. Furthermore, concrete formulas are created which are also mixed and tested. Finally, the proposed area for the test cements and economic evaluation per 1 m3 of concrete mix.

Stereometric LED display
Kováč, Michal ; Macháň, Ladislav (referee) ; Bohrn, Marek (advisor)
The bachelor thesis deals with the design of stereometric display made of the mesh of RGB LED arranged to the matrix of 8x8x8. The thesis copes with the options of diodes’ arrangement according to minimization of number of leads as well as building process of desired mesh. The device is controlled by FPGA circuit on the development board Spartan-3 Starter Kit and control circuit is described in the thesis. The information about displayed text and animations are transmitted into the circuit from computer through USB interface. The display is created, apart from Spartan-3 Starter Kit, by two connected boards which design is also described in the thesis. The first one presents the stereometric display itself with essentials components and the second one provides communication with the computer.

System for Serial Communication Monitoring
Perný, Jan ; Kováč, Michal (referee) ; Kolouch, Jaromír (advisor)
There is a need for a serial communication testing tool when software or hardware developers have to solve serial communication problems. This tool must accurately catch and record the whole communication. Some type of timestamps in the record is necessary for future analysis. This diploma thesis deals with programming a serial communication monitoring equipment software with the possibility of the insertion of timestamps. Possible timestamps types and inserting methods are also discussed. The programmed monitoring software for the FOX Board hardware platform is able to catch and record the serial communication at RS232 ports and add timestamps to the record in accordance to three independent rules. The record is saved to a standard USB flash drive.

Algorithms for analysis and processing of RFID signals in FPGA
Harvánek, Michal ; Kováč, Michal (referee) ; Derbek, Vojtěch (advisor)
The result of this thesis is the architecture design for a software-defined radio, which is used to analyze the signal emitted by RFID tags in real time. The aim of this analysis is to measure the frequency characteristics of the RFID tag. The main means for achieving the objective of optimizing signal processing algorithms and reduce the time needed to control the hardware compared to the classical concept of SW radio USRP. It is described how to obtain and display digitally sampled signals using a graphical programming language LabVIEW and subsequent processing of these data in MATLAB. Further described is the skeleton of the proposed solution.

Thermal sensors communication with CPLD using SMBUS
Tonar, Karel ; Rumánek, Jaroslav (referee) ; Kováč, Michal (advisor)
The goal of bachelor’s thesis is the introduction with two - wire circuit communication on the SMBUS, it is concretely related to alternate communication of FPGA with thermal sensors. The bachelor’s thesis also contains the choice of optimal thermal sensor, the proposal of module for measuring the temperature and proposal of programme for Programmable Logical Device. The programme processes data from the modules of temperature measurement and data are indicate on LED display. The programme makes it possible to display minimum, maximum and average temperature during certain time interval. All of programmes are implemented for logical device in VDHL language. The thermometer sends data to Personal Computer over UART interface. There is temperature displayed and storaged once again. During working on this bachelor’s thesis was used SPARTAN-3 starter board and design system Xilinx ISE 9.2i.

High speed acquisition system
Svoboda, Tomáš ; Kováč, Michal (referee) ; Kubíček, Michal (advisor)
This master's thesis is focused on the design of a highspeed aquizition system which is based on FPGA and a highspeed AD converter with modern JESD204B interface. Considering the requirements, such as high samplig rate, the current range of available devices is limited. Therefore the market overview of the modern IC and modules was made. The resulting design is based on available modules, so the rached sampling rate is up to 5 GSa/s with 12bits resolution. Data from measurement are send to PC via Ethernet which uses lwIp stack and TEMAC core on Microblaze proccessor.

Business Plan - Introduction of a New Product on the Market
Hajtmar, Adam ; Kováč, Michal (referee) ; Heralecký, Tomáš (advisor)
The diploma thesis is focused on the elaboration of a business plan for placing a product on the market. It is a robotic device for the maintenance of single-wheel rails. The equipment will be placed on the Czech market by companies that will be newly created for this purpose. The business plan will be based on experience from joint machine research as well as relevant analyzes. The plan is therefore aimed at the company successfully completing its entry into the Czech market.

Stepper motor control using CPLD
Daněk, Jan ; Kolouch, Jaromír (referee) ; Kováč, Michal (advisor)
The aim of my bachelor thesis was the control of CPLD stepper motor. To create a radio controlled antenna rotator. The controlling is done by a computer using RF circuits. The thesis includes a construction and principles of stepper motor. Basic structures of CPLD circuits were applying to create the control circuit. The possibilities of sensing the position and the data storage circuit were discussed. The control program in VHDL was implemented in development boards. The development board is connected to radio receiver circuit and the stepper motor driver. A transmitting board was connected to a personal computer or other device using RS232 interface. Printed circuit boards for transmitter and receiver circuits were created. The PC program was designed for data transmission. The program sends data and communicates via RS232 interface.
