GSM alarm for motorcycles
Beníček, Martin ; Fedra, Zbyněk (referee) ; Urban, Josef (advisor)
The main target of this work is to design and to implement unfailable safety appliance for motocycles with use any GSM technology. In my masters’s thesis I applied to individaul fields which I had to knows for realization of this work. The introductory chapter tells the reader about evaluation of former semestral projects and about brief description of the realized mechanism. It is followed by descripctoin of principles of communication between PC and mobile phone. The main part of my work is dedicated to application itself. The applicaton is called motoalarm. The last chapter creates description service of localisation mobil phones which is called Kde je... The conclusion includes evaluation of this master´s project and general description of the realized mechanism.

Self-priming pump
Urban, Jiří ; Hudec, Martin (referee) ; Pochylý, František (advisor)
Diploma thesis is focused on self-priming pump 25 - OVE Sigma pumpy Hranice s.r.o., for its function is essential the ejector which is placed in the body of the pump. On the basis of the results of measurements there are designed construction modifications using a mathematical model. For the first time were made measurements to verify the self-priming capability with determining the maximum suction height.

PAPR reduction in OFDM and simulation in Scilab
Maňák, David ; Maršálek, Roman (referee) ; Urban, Josef (advisor)
Main goal of this dissertation is read over principal and properties of the OFDM modulation. Onward we become acquainted with basic methods for PAPR dynamics reduction in OFDM such as Clipping or Interleaving. Simulation of reduction methods will be realized in Scilab environment, in which are made basic functions for OFDM modulator and demodulator. Furthermore there are created functions for PAPR reduction methods. All established functions are implemented in the GUI.

Communication Strategy for Company Ježek
Urban, Jan ; Zatloukal, David (referee) ; Šimberová, Iveta (advisor)
The goal of the submitted thesis: “Analysis of company´s communication mix” is the analysis of the company´s present communication mix and proposal of a new mix. The study is divided into two parts, theoretical and practical. Theoretical part discusses the established methods of analysis a company´s internal and external environment, describes and compares particular tools of marketing communication and its principles in the theoretical level. Introduction of practical part introduces selected company. Main part analyses company´s environmental and particular tools of promotion. Last part gives proposals of the new communication mix.

Optical characterization of perovskite nanostructures
Urban, Jakub ; Kvapil, Michal (referee) ; Dvořák, Petr (advisor)
The present bachelor's thesis focuses on the optical characterization of CsPbBr3 nanocrystals ranking among the group of materials called perovskites which are remarkable for their high photoluminescence (PL) quantum yield. An algorithm for a correlation of experimental data measured by PL mapping with morphological and topological properties obtained by using Scanning Electron Microscopy and Atomic Force Microscopy has been developed which clears the way for a particular crystal detection and their spectrum analysis. Specifically, crystals the shape of which can be approximated by a cuboid have been detected and the volume dependence of the centre of mass of their PL, which is proportional to V^(-2/3) as predicted by the theorethical model, has been discovered. The measurement of PL dependency on temperatures ranging from 40 to 60 °C has also been conducted and in this temperature interval linear dependence of the full width at half maximum of their PL spectral line that rises with rising temperature has been confirmed. On the contrary, the centre of mass of PL has been found to be temperature independent.

Variants of the first separation stage with two-stage water treatment
Urban, Jaromír ; Látal,, Milan (referee) ; Biela, Renata (advisor)
The subject of this bachelor thesis is to introduce the possibilities of the first separation stage with the two-stage treatment of raw water for drinking water. The thesis is divided into the theoretical and practical part. At the beginning of the theoretical part, I make research of raw water sources, requirements for their quality, the possibilities of water treatment for raw drinking water and the distribution of water treatment plants according to the number of separation stages. In addition, the first separation stage for two-stage water treatment is described in more detail, equipment and technology used for a given level of treatment and detail information of the individual types of the first separation stage. In the practical part of the thesis, two selected types of the first separation stage - settling tank and clarifier for specified design flow Q = 80 l/s are calculated. The following drawings are based on previous calculations. For the proposed rectangular settling tank with a horizontal flow and a clarifier with a mechanical float cloud, the ground plan, longitudinal and cross section are processed.

Urban viaduct in Povazska Bystrica
Kaut, Tomáš ; Urban, Jiří (referee) ; Nečas, Radim (advisor)
The content of the diploma thesis is design urban bridge in Považská Bystrica. From three possible options was selected one, which represents cable stayed bridge-extradosed with four spans. This selected option was elaborated in detail in this diploma thesis. Design procedures and assessments were performed to comply with ultimate limit state and serviceability limit state according to valid europeans standarts. The calculation model was performed in program Midas Civil in logitudinal axis and in SCIA Engineer in transversal axis. Structural assessment were done manually. The part of the diploma thesis are detailed drawings and visualizations.
