Numerical solution of incompressible Navie-Stokes equations on domains with moving boundaries
Šedivý, Petr
Autor: Petr Sedivy Nazev prace: Numericke feseni nestlacitelnych Navierovych-Stokesovych rovnic v oblastech s pohybujici se hranici Abstrakt: V praci nejprve pfedstavime rovnice popisujici proudeni tekutin a pote formulujeme jejich zjednoduseni, tedy Navierovy-Stokesovy rovnice, pripomeneme nektere potfebne vety a definice a zavedeme znaceni, ktere budeme v cele praci pouzivat. Navierovy-Stokesovy rovnice fesime raetodou konecnych prvku, kterou podrobne popisujerae auvadlmejednoduchypfiklad, feseny touto metodou. Dale resime stacionarni Navierovy-Stokesovy rovnice, definujeme slabe feseni a doka2aijeme jeho existenci a jednoznacnost pro homogenni okrajove podminky. Zabyvame se take nehomogennimi okrajovymi podminkami a nakonec se zabyvame nalezenim pfiblizneho feseni. Je zde take diskutovana problematika nelinearity Navierovych-Stokesovych rovnic. Pozdeji fesime nestacionarni Navierovy-Stokesovy rovnice, zabyvame se casovou diskretizaci a pfibliznym feseninx V dalsi casti fesime problematiku pohybujici se oblasti. Popisujeme metodu ALE a aplikujeme ji na Navierovy-Stokesovy rovnice. Zaver prace je venovany popisu metod, ktere jsme zvolili k feseni Navierovych- Stokesovych rovnic., a vysledkum. Na pfikladu, jehoz feseni znarae, porovnavame pfiblilne a pfesne feseni a ukazujeme, proc je vhodna volba...

Experimental analysis of air stream from a car blower using smoke method and design of the blower quality assessment
Krška, Lukáš ; Šedivý, Petr (referee) ; Jedelský, Jan (advisor)
The aim of this work was the analysis of air current from the right outlet, using the smoke method and the subsequent determination of a method for application. A further task was to establish a method for determining the upper and lower vertical routing, yaw angle (ß) and angle of inclination (?) of the air current. The experiment aims to approximate conditions as close to those experienced in the actual vehicle. After assembling a track with a soot blower (outlet) in the laboratory and defining the coordinates of the vehicle, the air current was subjected to visualization within the range of five positions of the vanes. Visualization was achieved by the use of technology for the smoke method. We used a light plane with a customized system of coordinates, a smoke generator for visualizing the air current being emitted and a camera for recording images. During our research we established the upper and lower cut off at the specific closures of the horizontal vanes of the soot blower. We determined a common analogy between the experimental track used in the experiment and the circumstances in the actual vehicle. We acquired the yaw angles (ß) and the angles of inclination (?) in the light plane and, after conversion, in the system of coordinates of the vehicle for all five settings of the vanes. The assessment of the given soot blower was undertaken according to the values achieved.

Valuation of Měšťanský pivovar v Poličce, a.s.
Šedivý, Petr ; Kislingerová, Eva (advisor) ; Strouhal, Jiří (referee)
The main aim of the thesis is to determine market value of the equity of Měšťanský pivovar v Poličce, a.s. to the date of 1. 1. 2015. There is a secondary goal to determine whether a small industrial brewery is capable to compete with large brewing groups. In the first part, the theoretical and methodological sections explain the basic concepts and procedures that are used in the practical part. The practical part itself is then devoted to the strategic and financial analysis, forecast of value drivers and financial plan. The actual valuation is performed using the method of income, assets and market value. The conclusion corresponds to the objectives set out in the introduction and discusses the relevance and usefulness of the results in practice.

Selection of the optimal loan for the selected client
ŠEDIVÝ, Petr
This thesis is divided into two parts. The first part is dealing with the theoretical definition of the research issues - loans and multicriteria decision making. The second part focuses on the factual selection of the optimal variant for the selected client's loan. In this selection was used methods of multicriteria comparison. It were also compared loans from banks and loans which are provided by non-banking companies.
