This diploma thesis deals with the control calculation of fluid biomass boilers with circulating fluidized bed. The introduction briefly introduced fluidized bed boilers and explained what biomass is. Furthermore there is a stoichiometric calculation of combustion. The calculation of the losses and the efficiency of the boiler is following. Desulphurization is calculated briefly. The main part is devoted to the design and calculation of individual heat exchanging surfaces: superheater P1, superheaters 2 and 3, the wall superheater, the return chamber, hanging tubes, economizer and air heater. At the end is calculated total tolerance boiler. Work is completed with a diagram of temperature of working media and combustion.

Nájemné bytu a faktory, které je ovlivňují ve vybrané lokalitě v Brně. / Apartment rent and the factors that influence it in a selected Brno location.Hlavenka, Roman January 2015 (has links)
Diploma thesis on the subjekt ,,Apartment rent and the factors that influence it in a selected Brno lokativ“ is dedicated to the analysis and comparison of the amount of the rent in the offered flats in certain aboriginal sites. It deals with the factors that have an effect on the varying amount of the lease. The obtained data are divided into categories according to size, and 1+1 and 1+kk, 2+1, 2+kk, 3+1, 3+kk, 4+1 and 4+kk. For each category is created map. The results are summarized in tables and charts, and finally, evaluated and textually.

Porovnání cen obvyklých a cen zjištěných porovnávacím způsobem u bytů v Ostravě / Comparison of normal prices and the prices identified by the comparison method for apartments in OstravaByrtusová, Ivana January 2016 (has links)
Locations of interest Poruba nad Ostrava-Jih are described in this master thesis. The analyse of real estate market is made in these Ostrava districts. The main result of this analyse is to define the range where the price of flat is with the high probability and to estimate the market value. Both locations are compared. After that the identified price and market value are calculate for two apartments of 3+1 disposition in these districts. The identified price and market value are compared. In evaluation is included the comparison of prices between both districts with clarification of specific reasons of differences.

Optimalizace výroby součástky z konstrukční oceli tl. 20 mm technologií laserového dělení / Optimization of a part production made of a structural 20 mm thick steel using laser cutting technologyŠoukal, Hynek January 2017 (has links)
The thesis deals with the optimization of process parameters in the oxidative laser cutting of structural 20 mm thick steel with regard to the type of material, the resulting roughness of the cut and the resulting price of the product. In line with the literary study and the Taguchi method, an experiment was developed. The cutting speed, laser performance, cutting gas pressure, and focal position were controlled during the experiment. Sample sets were cut with 7.5" and 10" focusing lens from the TATA STEEL S355MC and SSAB LASER 355 MC steels. According to ČSN EN ISO 9013, the samples were evaluated for roughness. Then micro and macro structures were evaluated, and compare the hardness according to Vickers. In conclusion, technical and economic evaluation was determined.

Energie ze zemědělské půdy / Energy from Agricultural LandŠatra, Jan January 2010 (has links)
Thesis is concerned with relation of usable energy and space as it's widely spread source. For this purpose are introduced not only a few indicators suitable to energy management description, but also principles of environmental assessment thinking are expained, as these help to distinguish the really sustainable ways of deriving energy from space. As examples of energy-from-space extraction are introduced photovoltaics, liquid biofuels and fast growing energy plants. After a brief entry to heat supply problematics, focus is remains on a simple case study: quantifying relationship between local heat demand and local potential production of solid biomass from short rotation coppice. This so far rather hypothetic relation is examined at the municipal level, while Central and South Bohemia regions are the target area. Soil characteristics and population census data (2001) about residental habitats are used.

Spline křivky s pythagorejským hodografem / Pythagorean hodograph splinesKadlec, Kryštof January 2020 (has links)
In this thesis the main object of our concern is a Pythagorean hodograph B- spline curve. We recall notions of both Pythagorean hodograph (PH) curves and B-spline functions separately first. Then we put these fields together to generalize PH curves to their B-spline instances. We encapsulate these curves in various spaces under one algebraic structure using the formalism of Clifford algebras. We consider both Euclidean and Minkowski spaces of lower dimensions which give room for real applications and use of these curves. We support our results by giving numerous examples. 1

Budoucnost brněnského výstaviště / Brno Trade Fairs FutureBeltiukov, Ilia January 2019 (has links)
The architectural project of Exhibition Hall is located in a part of Brno-Pisárky, in northern area of BVV. The objective of the land-use planning and architectural proposal was to integrate the Hall in proximity to the second entry of BVV. The pavilion is situated on the primary northen axe, which perpendiculary join the pedestrian bridge. The binding foot-bridge is used for path between the entry of BVV and the western entry into the exhibition section. Surrounding the building is situated green park. There are open areas for pedestrian, tree-hemmed paths and relaxation spots around the entire building. The exhibition hall combines four basic parts: the western entrance connected with the pedestrian bridge, public part, storage part and the multi-purpose exhibition space in between. There are two-floor restaurant and snack bars with an open view to the south part of BVV, in particular to the Hall Z. The pavilion was concieved as a ruled rectangular volume. The creative proposal was to involve the ruled surface geometry, which is formed by connecting two curves with a series of straight lines and covers the entire building. The outer curtain wall is implied «the Curtains», reveals a lightness and airiness by dynamic effect. Geometrical curved profiles clearly point the basic entry spaces outside the exhibition hall. The western entry section allows two different points of entrance: from the pedestrian bridge to the first level and from the ground level. In time of trade fairs there are possibilities to use industrial doors along northern and southern elevations as a secondary entrances. There is a lobby space with the monumental staircase in the centre of public section. The circular shape of staircase rises towards atrium. A collaboration of atrium and natural lighting optically extends and makes easier the foyer space. In addition to the trade fairs, the multi-purpose exhibition hall permits diverse possibilities of using – in time of cultural and sports events u

Vliv individuálních vlastností samců páskovce kroužkovaného (Cordulegaster boltonii) na jejich epigamní chování / Golden-ringed Dragonfly (Cordulegaster boltonii): Effect of individual male characteristics on their epigamic behaviorRohlíková, Barbora January 2018 (has links)
My study researches the individual male characteristics of Cordulegaster boltonii in relation to their epigamic behavior. The first part of this study analyzes the relations of the measured characteristics (length and height of the wing, wings area, body weight, age), in the second part I assess their possible effect on the epigamic behavior of males of Cordulegaster boltonii, specifically how they affect the intensity of searching for females. Males of this species perform distinctive scanning flights over a stream to find an ovipositing female to mate with her. I used individually marked males to quantify their performance which can be interpreted as reproductive success because more active males are more likely to meet and mate females. My work includes 3 methods of evaluating activity. The first is based on the actual number of flights, the second on the average daily order of the males (based on the number of flights in days when the males have been seen). The third method combines the average daily order with number of days when the males could be seen. In the second part of the study I evaluate the effect of the above-mentioned individual characteristics on the flight activity of males. The outcome of the GLM indicates that the only characteristic with significant effect is the age of the...
