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.

Antenna for universal transmitter
Daněk, Jan ; Láčík, Jaroslav (referee) ; Láčík, Jaroslav (advisor)
This work describes an electrically small antennas used for mobile devices in the ISM band. The aim of this work is to select an antenna for a universal transmitter/receiver working in the 868 MHz band. The work contains description of the universal transmitter/receiver, and a list of suitable antennas. Tolerance analysis is performed by numerical model. The proposed antenna is manufactured and measured.

System for Bibliography Database Management on the Internet
Daněk, Jiří ; Janovič, Filip (referee) ; Rajmic, Pavel (advisor)
The aim of this master´s thesis was to create a web interface for working with bibliographic quotations. This whole project was created to easy writing bibliographic quotations in author´s piece. The system allows inserting, searching and managing bibliographic quotations. These quotations can also be exported into four types of files : RTF, XML, HTML, a database bib file. The czech norms CSN ISO 690-1 and also CSN ISO 690-2 are fully supported. Whole the system is based on language like PHP which is used for developing dynamic web pages. The system contains graphical user interface, which is simple to use. The web interface is fully functional and it is ready for using by autors of scientific publications or students in schools.

Effect of growing openness of Turkish economy on income distribution
Daněk, Jakub ; Jiránková, Martina (advisor) ; Kačírková, Eliška (referee)
Turkey is a country that in the last three decades has undergone significant changes and developments leading to greater openness of the economy. It is also a member of OECD exhibiting one of the highest levels of inequality of income distribution. The purpose of this thesis is to analyze the relationship between the openness of the Turkish economy and the distribution of income and verify whether this relationship develops analogously to the Kuznets curve. First, this paper deals with political and economic developments in Turkey between 1980 and 2012. Then, I approach the problem of inequality of income distribution and using the Gini index quantify and comment the income inequality. The final part is devoted to examining the relationship of openness of the economy and inequality of income distribution and verifies the assumption of an analogy to the Kuznets curve.

Options effective use of private insurance for chosen agricultural company
Daněk, Jan ; Šlajs, Jan (advisor) ; Vebrová, Ludmila (referee)
This aim of this thesis is to tackle the effective use of risk management within private insurance for a selected agricultural company. The paper suggests that it is fundamental to identify such a risk and subsequently define it. Consequently, the identified risk is analysed along with the concept of insurance, which is also essential for work. After an analysis of agricultural insurance in the Czech Republic, the paper further compares the variety of insurance available as offered by local insurance companies. The state's point of view is scrutinized in relation to the variety of insurance offered, as the state provides the Support and Guarantee Fund and Agricultural and Forestry Fund, Inc., which provides subsidies to the farmers. Subsequently, the paper demonstrates the importance of the insurance broker, who acts as a mediator between the insurance company and the farmer. In conclusion, the paper will contemplate to illustrate a real-life example in an agrarian society.
