Interval linear systems with linear dependencies
Král, Ondřej ; Hladík, Milan (advisor) ; Rada, Miroslav (referee)
The main problem discussed in this thesis is about finding an enclo- sure of the solution set of an interval linear system with linear dependencies. We get familiar with definitions from interval arithmetic and analysis. Then we extend them to matrices and linear systems, where we introduce several modern approaches to finding an enclosure and divide them thematically. Most of them are implemented in MATLAB using INTLAB library. We compare their precision and computational time on Toeplitz, symmetric and random matrices. For depen- dencies we design our memory saving representation. The results are interpreted and the final function, which can compute either fast, sharp or memory efficient, is build on individual methods. Powered by TCPDF (www.tcpdf.org)
Design of steam boiler with grate firing burning contaminated wood
Král, Ondřej ; Křemínský, Pavel (referee) ; Baláš, Marek (advisor)
The master´s thesis deals with steam boiler design that burns contaminated wood with output 55 tons of steam per hour, steam pressure 4,2 MPa and temperature 423 °C. First two chapters focuses on stoichiometry and calculation of heat losses and boiler efficiency. Great part of thesis constitutes of thermal and dimensional calculations of every heat transfer surface. Some specific boiler parts are described considering special fuel properties. Final chapters contain pressure losses calculation of flue gas and heated medium for pumps and fans design. Drawing is also part of the work which is included as an attachment.
Application of modern technologies for the production of spare parts airsoft guns
Král, Ondřej ; Zemčík, Oskar (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis describes design and manufacture of airsoft spare parts. Selected spare parts were hammer and spring holder, which were designed in 3D parametric software Autodesk Inventor 2016. Chosen method to manufacture spare parts, was Fused Modeling Deposition, which is part of Rapid Prototyping technology. The device for producing parts was 3D printer uPrint. The manufacture of silicon mould was based on printed spring holder, which was used for parts manufacture, by casting plastic materiál. Thesis is completed with a technical-economical evaluation, in which it was found that the silicon mould casting is more profitable in the production of more parts.
Wind energy
Král, Ondřej ; Brázdil, Marian (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis discuss wind energy sector. The first chapter focuses on basic construction types of wind power plants, their classification and description of the main parts. Basic physical principles by which electrical energy is produced, presents the next section, which deals with the lifetime of wind turbines, too. The final chapter describes the development of wind power in history, wind energy is here compared with other energy sources, and finally it is dedicated to matter of wind turbines’ energy payback.
Power analysis
Král, Ondřej ; Malá, Ivana (advisor) ; Bílková, Diana (referee)
This thesis examines the issues of analysis of statistical power of a test. It introduces a subject of hypotheses testing which is closely related. The goal is to expose the effect of parameters' alteration on the power test size. By using an application on examples, the thesis graphically illustrates the differences caused by the parameters' alteration. The results show how is the power of a test influenced by the effect of type one error, type two error, the number of observations, the formulation of alternative hypothesis and effect size on test power. The thesis further elaborates on effect size forms. In conclusion, all the explained theories are tested by an example that illustrates the size, which is achieved by changing the parameter.
Internationalization of the renminbi in the context of building the foundations of Chinese hegemony
Král, Ondřej ; Jiránková, Martina (advisor) ; Bejkovský, Jan (referee)
In the 21st century, the Chinese currency gradually gains its position in the international monetary and financial system. The pace of making structural reforms in China is accelerating. These reforms are supposed to start a new growth model of the local economy. The base of this development is the internationalization of the renminbi. It is among the means by which China wants to achieve sustainable growth and in a longer term attack on hegemonic position in the world economy. This thesis examines the extent to which the renminbi becomes the world's tender and the impact this fact would have on the layout of the world economy, hence on China itself.
