<p>U disertaciji je izvršena karakterizacija sliv nosioca flekso<br />štamparskih formi i predstavljena su istraživanja uticaja promene<br />mehaničkih i adhezivnih svojstava slivova na parametre kvaliteta<br />štampe kartonske ambalaže. Korišćene su dve grupe samolepljivih<br />slivova (potpuno novi i slivovi korišćeni za štampu 5.000.000 m<br />materijala). Ciljevi istraživanja su povećanje predvidivosti i<br />konstantnosti kvaliteta štampanog proizvoda i procesa proizvodnje<br />kartonske ambalaže, formiranje preporuka za upotrebu slivova<br />različitih svojstava i nivoa eksploatisanosti i otkrivanje u kojim<br />fazama i kojim procesima dolazi do promena svojstava slivova.</p> / <p>Research presented in this dissertation includes characterization of<br />flexographic sleeves and the study of the influence of the changes in<br />mechanical and adhesive properties of the sleeves on print quality<br />parameters of the cardboard packaging. Two groups of self-adhesive sleeves<br />were used (entirely new and sleeves used for printing of 5.000.000 m of<br />material). Aims of the research are the increase in predictability and stability<br />of the printed product quality and the production process of cardboard<br />packaging, forming of the recommendations for the use of sleeves with<br />different properties and levels of exploitation, as well as defining the phases<br />and processes responsible for the changes in sleeve properties.</p>

This diploma thesis deals with the separation of aerosol particles on membranes from polypropylene hollow fibers. As a source of particles, a desktop 3D printer using polymer filaments was used. Filtration efficiency and a pressure drop on a hollow polypropylene fiber membrane and a high efficiency particulate filter (HEPA filter) were monitored during filtration of particles from 3D print using filaments of acrylonitrile butadiene styrene, acrylonitrile styrene acrylate, polylactic acid and polyethylene terephthalate glycol at nearly the same air flow. The results achieved by both filer media are then compared and discussed. The results show that the hollow fiber membrane achieves better filtration efficiency at higher particle concentrations, while using the less emitting materials, the efficiency of the HEPA filter was higher or the same. The total filtration efficiency calculated from all experiments with all filaments was higher for the hollow fiber membrane with higher pressure drop at the same time.

This thesis called "Printed Media Photographs ahead the Elections (Chamber of Deputies of the Czech Parliament, 2006)" brings an analysis of politicians'picture in the five quality-press newspapers ahead of the elections to the lower chamber of the Czech Parliament. This analysis uses the quantitative content analysis, follows up emergence of issues and draws comparisons among the newspapers and political parties. This thesis sums up the main aspects of the photographs in the printed media ahead of the Elections. There are up to 90 graphs that simply show the outcomes even of the multilevel analysis. Analysed daily newspapers were the following: Hospodářské noviny, Mladá fronta Dnes, Lidové noviny, Právo and Haló noviny. The analysis was done by means of the SPSS statistical software.

This master thesis deals with a study of directional antennas, followed by their design and optimalization of horn antenna based on SIW for Ka band (26,5- 40 GHz). The first part of the thesis contains the theoretical analysis of the different types of directional antennas, also the SIW technology is described here. It also describes the 3D printing technology by means of which the final antenna should be made. The next part of this work is about design of horn antenna based on SIW. Simulation and optimization of the antenna will be done using the CST Microwave Studio. The final part of the thesis deals with evaluation of achieved results.

The aim of the work was design and realization of device to simplify and speed up the testing of AWS / TPWS train protection system. The first chapter is addressed to description and division of train protection systems. The next chapter describes the process of commissioning the AWS / TPWS system and possible applycation of the device to this process. The final chapters deal with design, specification of components, realization of device and verification of its functionality.

This thesis concerns automation of software and hardware testing using the robotic testing system called RQA. It aims to design an interface to produce test scenarios using the robotic testing system. Next it elaborates metrics measured during testing used for quality assurance of the system uder test. One of the topics covered is a visualization of test data and measurements for an easy overview of quality.

This thesis deals with 3D printing, materials used for 3D printing, testing of the materials and learning their real parameters. Goal of the thesis is comparing selected materials, executing series of mechanical test and selecting suitable material for printing high-quality plastic parts for use in automobiles, especially for reproduction of parts that are no longer made for oldtimers and for use in motorsport.

This master thesis is about design and construction of FDM delta 3D printer which consists of 32-bit electronics, magnetics printer head and other necessary peripheries. Opening chapters of this thesis are about theory of 3D printing and its methods with description of FDM 3D printers and summarization of FDM plastic materials used for 3D printing. The next part is about used electronics and problematic of heat transfer. The main part of this thesis describes design and construction of 3D printer and its necessary peripheries, which includes creation of its 3D model and application for 32bit controller. 3D model of delta 3D printer and its heating components was created in CAD software SolidWorks. The last part includes description of commissioning and calibration of delta 3D printer with summarization of economic aspects of its creation.

It also describes the 3D printing technology by means of which the final antenna should be made. The next part of this work is about design of horn antenna based on SIW. Simulation and optimization of the antenna will be done using the CST Microwave Studio. The horn antenna was modeled with three different dielectric loads. The horn antenna with an experimental triangular dielectric load was chosen for fabrication. The fabricated antenna has reached almost the whole bandwidth to cover Ka. The antenna gain was 9,38 dBi for 33 GHz frequency.

This thesis deals with the application of smart cameras and verification of its functions. In the first part the term smart camera is defined, the parts of it and the most common applications are presented. A review of smart cameras from the different manufactures on the market is made. After selection of the proper camera model three task from real industrial application are specified – inspection of capacitor print, inspection of beer label and dimension measurement. With the picked camera the tasks are performed, including the layout of workplace, scene and lighting. Further the reliability is tested together with the successfulness and the speed of designed solution.
