Multicarrier modulator and demodulator for software defined radio
Klučka, Jaroslav ; Urban, Josef (referee) ; Maršálek, Roman (advisor)
This thesis deals with computer simulation of the communication chain using the OFDM modulation. In the beginning of my thesis there is a brief description of digital modulations, especially OFDM. The model of the transmitter, radio channel and receiver, including a simple timing and frequency synchronization and equalization is designed and simulated in the Matlab environment. There is a designed communication system implemented into USRP development board in the Simulink environment. The development board could not work simultaneously as a transmitter and as a receiver. Function of the transmitter was verified by measuring on spectrum analyzer. Testing OFDM signal using the arbitrary waveform generator CompuGen 4302 was generated for the verification of the function of the receiver. Testing signal was received and demodulated on the development board which works as a receiver.

Prestressed bridge No. 202 on the expressway R2 in Slovakia
Janek, Tomáš ; Urban, Jiří (referee) ; Koláček, Jan (advisor)
My diploma thesis deals with design of the bridge number 202 on expressway in Slovakia. The bridge leads across the road number I50 (between Trenčín and Bánovce nad Bebravou) and railway number 130 (between Trenčín and Chynorany). For each course there is a separate super-structure. Only left super-structure is considered for the work. The box girder with four spans is chosen from three variations. This bridge is designed according to limit states, construction´s influence on design is taking into consideration. Structural model of construction is made as a spatial bar model. Structural analysis, well arranged drawings and visualization are elaborated in this thesis too.

The study of the reconstruction of the pool water treatment plant of the summer swimming pool Břeclav
Urban, Jaromír ; Látal,, Milan (referee) ; Biela, Renata (advisor)
The subject of the diploma thesis is to introduce the problems of communal spas, namely the treatment of water for swimming pools. Following is a proposal of reconstruction of the treatment plant for a real, operated area of the summer swimming pool. The thesis is divided into theoretical and practical part. At the beginning of the theoretical part I make research of the history of balneology, the effects of bathing and swimming on the human body, possible resources for spa purposes and hygiene requirements for these waters. I also describe commonly used methods of treatment of swimming pool water. In the practical part I first describe the summer swimming pool in the town of Břeclav. There is a description of the swimming pool, its history and equipment. In the next chapter I present the currently operated technological line. Based on a personal visit, the next chapter evaluates the technical condition of the plant. Based on this evaluation, a new technological line for treatment of swimming pool water of the Břeclav summer swimming pool is proposed.

Study of Distribution Logistics in K-BREWERY TRADE
Navrátil, Ondřej ; Urban, Jan (referee) ; Bartošek, Vladimír (advisor)
In my bachelor thesis is a subject the study of distribution logistics in K Brewery Trade. The study is separated into three parts, theoretical, analysis and my own proposal of solution. The first part is focused on the theory of clasification of transport, logistics of transportation and characteristics of carriers and transport services. Analysis is focused on the form of distribution networks and the criteria for transport of goods between distribution centers of the selected company. My own proposal of solution is developed according to materials from the company.

Inovation of laboratory tasks from BLOS
Urban, Jakub ; Valach, Soběslav (referee) ; Holek, Radovan (advisor)
This thesis deals with innovation of tasks from bachelor subject Logical systems. Three tasks in total in VHDL language were designed and tested for development kit Digilent Nexys 3 and peripheries Pmod which are connected to it. First task is focused on reading pressed key on matrix keyboard. Second and third tasks targets on displaying pressed key on OLED display, they differ by used controller for this display. Instructions for all tasks were created.

OFDM demodulator implementation in FPGA
Solar, Pavel ; Urban, Josef (referee) ; Maršálek, Roman (advisor)
The master's thesis briefly analyses the principle of OFDM modulation, possibilities of the synchronization and channel estimation in OFDM. The simply model of OFDM system is made in MATLAB. Because of the implementation in FPGA is generated the behavioral description of the OFDM demodulator through the combination of the schematics description and the description in the VHDL language. The ISE development environment is used.

Trailer frame PILLAR for transport concrete pillars
Urban, Jiří ; Kašpárek, Jaroslav (referee) ; Kašpárek, Jaroslav (advisor)
The aim of this thesis is an analysis of the construction of a trailer used for transporting concrete pillars. The main part of the thesis is focused on frame construction. For the calculation of load states a multi body system was used, whereby a simulation of transport in terrain was performed. The results from these calculations will be used as limiting conditions for strength control. The method of solution is the finite element method. All acquired results will be analysed and according to them changes will be made to the frame construction. In addition to this, the thesis contains drawings documenting the above-mentioned changes.
