Design and lay-out of high pressure pumping station.
Václavík, Tomáš ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
The aim of diploma thesis is design and lay-out of high pressure pumping station with plunger pumps for splash of scales from slabs of hot-rolled. Theoretic (introduction) part of this thesis contain description of formation of scales and description of ways how it is possible remove these scales. And this part contains also explication of effect of water jet on solid material. The practical part of diploma thesis is focused on design of pumping station including of dimensioning of machinery. Part of this work is also technical documentation for proposed pumping station and specification of main machines and devices.

Internet library of methods and algorithms used for medical image registration
Koňařík, Jakub ; Fedra, Petr (referee) ; Peter, Roman (advisor)
Image registration is a procedure which is heading to search for a geometric transformation, which ensures same position, orientation and size of coresponding objects in pictures. How does these methods work? These methods and principies are explained in first part of this work. Second part of this work is aimed to explain theory about information systems and practical creation of the internet databaze. These practical part was realized in editorial system called Drupal.

Computational analysis of residual stresses in autofrettaged high pressure rails
Blaha, Jakub ; Petruška, Jindřich (referee) ; Vrbka, Jan (advisor)
The master‘s thesis is aimed on numerical simulation of autofrettage of high pressure fuel vessel – rail in Common Rail system. First there is described Chaboche model, which is later used for simulation of autofrettage. There are described different approaches which can be used to obtain sufficient material model. Then there is observed influence of these different approaches on stress state of rail within the process of autofrettage. Suitability of Chaboche model for autofrettage and re-autofrettage simulations is assessed by comparing with more complex Jiang model. In the end there is a study of influence of autofrettage pressure on different properties, especially on residual stresses.

Fitting and Extrapolation of Turbocharger Turbine Maps
Vondrák, Adam ; Babák, Martin (referee) ; Novotný, Pavel (referee) ; Štětina, Josef (advisor)
Modelování turbínových charakteristik je nutným předpokladem pro detailní simulaci výměny náplně válce turbodmychadlem přeplňovaných spalovacích motorů. Kromě toho je možnost stanovení účinnosti a průtokové kapacity v libovolných pracovních bodech klíčová pro porovnání různých turbínových stupňů. Cílem této práce je předložit jednotnou metodu pro oba účely tak, aby bylo možné provést porovnání použitím přesně stejných modelů turbín jako při následné simulaci pracovního oběhu motoru. Zdrojem vstupních dat je obvykle měření na plynové zkušebně, které však umožňuje zachycení pouze omezeného pracovního rozsahu turbíny. V této práci jsou navrženy metody umožňující zvýšení věrohodnosti a robustnosti extrapolace turbínových charakteristik, přičemž optimalizace je využita k určení takových parametrů hledaných funkcí, které vedou k nejlepší shodě mezi modelem a vstupními daty.

Fittings of heating systems
Klus, Lukáš ; Adam, Pavel (referee) ; Počinková, Marcela (advisor)
The theme of this diploma thesis is fittings of heating systems and it is divided into three parts. The first part deals with this topic on theoretical level. In the second part, there is a calculations and drawings that deals with heating and water heating of the apartment building in Uherské Hradiště. This part is solved in two variants concerning hydraulic balancing and regulation of the heating system. The last part of the thesis is an experimental solution and processing of pressure loss results of selected valves. These results are compared with the values reported by the manufactures of the valve.

Synthesis of astronomical images
Sauer, Petr ; Babinec, Tomáš (referee) ; Červinka, Luděk (advisor)
The aim of this work is to create a program for fitting astronomical images. The input image is corrupted by atmospheric influences. The work describes the way the alignment and fitting methods. To select appropriately aligned images are used filtration method "Lucky imaging". The program is created in the "Matlab" and is controlled via a graphical user interface.

Heating of multifunkcional building
Kořenková, Veronika ; Formánek, Marian (referee) ; Počinková, Marcela (advisor)
The goal of this bachelor thesis is to introduce a heating system solution for multifunctional building. Thesis is divided into theroretical, calculation and project parts. Theoretical part is focused on the definition of fittings in heating systems. Second part depict the proposal of heating system and heat preparation of the multifunctional building, which contains veterinary clinic and housing units. Gas condensing boiler is chosen as a source of heat. The building is heated by steel panel radiators and towel rail radiators. Preparation of hot water is done by two indirect heating water storage tanks. Preheating of water is supported by solar collectors. Project part of the thesis contains technical report and drawing, based on the calculation part.

Impedance spectroscopy characterization of perovskite solar cell materials
Křečková, Jitka ; Vanýsek, Petr (referee) ; Novák, Vítězslav (advisor)
The Master‘s thesis deals with the topic of perovskite solar cells with the main focus on the materials used for the active layer. In the introductory part, the electrical and optical properties of halide perovskites are described and specific examples of perovskite crystals are introduced. The description of impedance and photoimpedance measurement methods used for characterization of perovskite solar cells is also included in the thesis. The measurement of electrochemical impedance spectroscopy was conducted on four perovskite crystals and equivalent circuit was formed to fit the obtained data. Parameters of the circuit elements were acquired using the fitting method and were further evaluated in experimental part of this thesis.
