Numerical simulation of the fire diffusion in mining passage
Michalec, Zdeněk ; Kozubková, M. ; Bojko, M.
Numerical simulations of the stable stratified flow in a 3D passage affected by a thermal source have been calculated with a standard k-e model. Furthermore, the radiation heat transfer model is implemented and species transport equations are defined too. The model allows a correct stratification and produces fairly accurate heat wall transfer.
Numerical solution of some 2D incompressible flow using dynamical effects
Honzátko, R. ; Horáček, Jaromír ; Kozel, K.
The work deals with a numerical solution of 2D inviscid incompressible flow throuht a cascade and over a profile in a channel. The finite volume method in a form of cell-centered scheme at triangular and qudrilateral mesh is used. the composite scheme applied to a numerical solution consists of more dissipative part adn less dissipative par. Governign system of equations is the system of Euler equations.
Modelling of cavitated flows in hydraulic machinery using viscous flow computation and bubble dynamics model
Sedlář, M. ; Maršík, František ; Šafařík, Pavel
Numerical solution of the 3D Reynolds averaged Navier-Stokes equation is based on FEM. The turbulence is modelled through the high Reynolds number k-epsilon model. The cavitation region is modelled as a region of the lower density . The local radius of cavitating bubbles is obtained as a solution of Rayleigh-Plesset equation. The flow past the blades of an axial flow mixer is calculated.
Počítačová simulace a experimentální studie hydrodynamického chování toku tuhá fáze kapalina
Křišťál, Jiří ; Jiřičný, Vladimír ; Staněk, Vladimír
In this paper basic parameters of multiphase flow simulation and experimental determination of particle velocity profiles are described.
Analysis of modern instruments on capital markets
Matyáš, Radko ; Veselá, Jitka (advisor) ; Žilák, Pavel (referee)
This thesis is focused on some of the new instruments on capital markets -- specifically on Investment Certificates, Warrants, Exchange Traded Funds and Contracts for Difference. It shows fundamental principle of behavior, important specifications and comparison to other investment products. The text further examine overall instruments' offering especially on the European markets and compare trading possibilities of the main brokers in the Czech Republic. The work analyses price changes of the instruments and related underlying assets and examine risk and profitability with respect to the latest global financial crisis.
Investment products of ETF and CFD
Gordan, Branislav ; Witzany, Jiří (advisor) ; Witzany, Jiří (referee)
Bachelor work describes two independent investment products, ETF (exchange traded funds) and CFD (contract for differences). My work is divided into two parts. First part describes function, and development of ETF. Second part includes information about CFD and their function, advantages and disadvantages. In the end, we can find comparison between these products. and prediction of their future on the stock market.
Investments in selected commodities
Pecha, Martin ; Drozen, František (advisor) ; Filipová, Vladimíra (referee)
The goal of this bachelor thesis is to analyse selected commodities being as follows: Crude oil, Gold and Coffee. I tried to make a go of showing readers, potential traders how to invest in the above mentioned commodities in regard to risk. The thesis is made up of three chapters. First one introduces the readers to commodity exchange issues paying attention to trading those commodities, commodity exchanges, commodity investment tools, a typology of commodity traders and other particulars expanding on the given field. Second one is geared towards an analysis of the above stated commodities in today's globalized world and depicts how specifically to purchase or sell these commodities. At last, I shall sum up existing pieces of knowledge and state premisis to be fulfilled in order for the traders to be at least a little successful at commodity trading.
Měnové deriváty
Dolejš, Pavel ; Revenda, Zbyněk (advisor) ; Žďárek, Václav (referee)
Tato práce se zabývá problematikou derivátů se zaměřením na měnové deriváty. Věnuje se jejich vývoji, doplňuje současné charakteristiky derivátových trhů. Dále rozebíra v jednotlivých kapitolách měnové opce ( věnuje se historii vzniku, zmiňuje Garman-Kohlhagenův model pro jejich oceňení a zmiňuje problematiku implikované volatility, kde uvádí výsledky studií zabývajících se tímto tématem, dále futures a forwardové kontrakty a nakonec je zmíněn CFD kontrakt.
