Odrazná plocha osobních automobilů / Radar cross section of passenger cars

Hanslík, Radovan January 2020 (has links)
This diploma thesis is aimed at radar cross section of passenger cars. Basic scattering parameters of simple targets are described. Selected numeric methods used for computing radar cross section are discussed. Shape and size of simplified vehicle models is investigated. Simulations are verified by computing RCS of objects with well-known characteristics. Radar cross section of Skoda Octavia was simulated using selected numeric methods. Results of all performed simulations are shown in included graphs. Experimental measurment of radar cross section of a vehicle was performed so the measured data can be compared with the simulations.

Změna palivové základny uhelného kotle / Changing the fuel base of the coal boiler

Přikryl, Josef January 2020 (has links)
The diploma thesis contains calculations of gasification of coal boiler. The first part of thesis contains stochiometric calculations, heat balance and calculations of combustion chamber. In the next part are calculations of heat exchange surfaces and at the end of this part are calculations of regenerative air heater and total boiler balance. Calculations are made by regard to investments costs, preservation of the steam parameters and keeps emissons limits.

Návrh projekčního osvětlovače / Design of projection illuminator

Přikrylová, Ivana January 2016 (has links)
The aim of this diploma thesis is to design a suitable reflector concentrating a light beam into a circular hole in a gobo. The light beam behind the screen should have good efficiency and at the same time good homogeneity. For the reflector design and analysis a software for designing optical systems called LightTools was used. The reflector was designed by six different methods. Several smooth and several faceted reflectors were designed. The selected reflector was analyzed in combination with a varifocal lens. For selected reflector was designed mechanical store with respect to the anticipated operating conditions. This thesis serves as the basis for the producing of the reflector.

Biomass estimation of European beech stands

Veselský, Marek January 2017 (has links)
Forest ecosystems plays an important role in the global carbon cycle of carbon sinks of terrestrial ecosystem. Carbon sequestered or stored in forest trees is mostly referred to as the biomass of tree, site or forest. This diploma thesis deals with biomass estimation of European beech stands at the Holíkov (the Drahanská vrchovina Highlands) and Štítná nad Vláří (the Bílé Karpaty Mts.) study sites in the Czech Republic. Study was conducted in the period of 2010 to 2015. 65 allometric equations were tested for the purpose of determining the most suitable candidate for the estimation of aboveground and belowground biomass of stands and of all the major tree compartments. It is obvious from the results that the allometric equations performed very differently from each other. It was also found, based on the obtained results, that the most suitable allometric equations for the study sites are by Vejpustková et al. 2013 and Wutzler et al. 2008.

Současné možnosti regenerace veřejných prostorů v panelových sídlištích / Current options for the regeneration of public places at the urban settlements

Vraníková, Radmila January 2013 (has links)
is thesis deals with the new approach to solving the usage of the urban places located at the current build-up area of the block of flats. On experiences from long-term processing of concrete designs there are introduced principles and fundamentals for the regeneration of public places at block of flats, including new structure of functional areas. These principles and fundamentals will serve as the methodical aid for the public service, self-government and for the designers conversant with regeneration of public places.

Univerzální pracovní plocha ve webovém prohlížeči / Universal Working Sheet in Web Browser

Máčel, Lukáš January 2009 (has links)
This master thesis is engaged in analyzing working desktop accessible from internet by web browser. It describes technologies required for building web interfaces such as DOM, document event model and AJAX. This master thesis contains also design of working desktop prototype. The desktop is implemented as web application based on client-server architecture. The client part of application represents web interface for managing document links placed on desktop. The desktop content is classified by panels and tabs. User can change link arrangement using drag & drop. Server part of application guarantees persistence of desktop configuration and making link offer. Working desktop prototype is implemented by Javascript library Dojo.
