Measurement of Dialyser-Membrane Diffusion Coefficient
Kašák, Pavel ; Bartoš, Michal (referee) ; Jiřík, Radovan (advisor)
This thesis focuses on the measurement of diffusion coefficient of dialysis membrane. The first part describes possibilities of membrane modelling. Basic models, which allow us to determine the basic characteristics of dialysis membranes like permeability and diffusion coefficient, are described. Next chapter deals with basic types and properties of membranes. The main part focuses on making the experimental installation, which is used to simulate permeance of contrast agent, used in DCE-MRI, through dialysis membrane. The last theoretical chapter describes calculations used to estimate diffusion coefficient. Practical part of this thesis uses a designed experimental installation for estimation of diffusion coefficient for two contrast agents Gadovist® and Multihance®.

MRI Acquisition of Image Sequences for Preclinical Perfusion Imaging
Krátká, Lucie ; Bartoš, Michal (referee) ; Jiřík, Radovan (advisor)
The task of this thesis is to study methods for the acquisition perfusní imaging based on dynamic MR imaging with T1 contrast. It describes methods of measurement of T1 relaxation time and the possibility of evaluating the results. It further describes the phantoms and their use. And it is here mentioned for the dynamic acquisition protocol perfusní imaging. There is also described in detail created a program for automatic control of the NMR system. In the experimental measurements are performed on static and dynamic phantom, are also evaluated perfusion parameters from the Flash sequence.

Image Formats
Wolanský, David ; Bartoš, Michal (referee) ; Jiřík, Radovan (advisor)
The thesis deals with a detailed analysis of the GIF file format. It is divided into two basic parts, theoretical and practical. The theoretical part includes a thorough analysis of the internal file structure, i.e. the description of the individual block types, of which the file consists. Each block-type characteristic includes properties and a detailed description of its individual items. This part also includes a brief description of the most common compression methods applied in the field of image compression. The practical part includes the design and implementation of an edutainment application for synoptic viewing of the internal structure for a chosen GIF file and its parameters. The implementation of the application covers algorithms for selection of individual block types and realization of a graphical user interface.

MRI Acquisition and Preprocessing of Image Sequences for Clinical Perfusion Imaging
Krchňavý, Jan ; Bartoš, Michal (referee) ; Jiřík, Radovan (advisor)
This thesis describes the theory for static and dynamic magnetic-resonance imaging using contrast agents affecting T1 relaxation time. The available acquisition methods in the specified facility of Masaryk Oncological Institute in Brno are described. The sequences for subsequent experimental measurements are selected. The used phantoms are described. Acquisition protocol for measuring is described briefly and the evaluation method for the measured data is suggested. The best acquisition sequence and a method of measurements is chosen influenced by estimation of relaxation time T1, sensitivity and signal to noise ratio. Perfusion analysis is executed and perfusion parameters are calculated. The work was supported by the European Regional Development Fund and the State Budget of the Czech Republic (RECAMO, CZ.1.05/2.1.00/03.0101).

Audiovisual stimulator
Bartoš, Michal ; Čech, Petr (referee) ; Hrozek, Jan (advisor)
The main objective of this study is to learn about the audiovisual stimulator and to create hardware resolution of stimulation LED glasses and in environment of the program LabView application, which operate this stimulation LED glasses and in the same time create sound of stimulation. Use environment of the program LabView. Application, which is create in environment of the program LabView, enable operate stimulation LED glasses and arrange sound from three source with two different method, which use modern AVS. Application contains a lot of security, informative and agreement components.

Deconvolution in perfusion imaging
Líbal, Marek ; Havlíček, Martin (referee) ; Bartoš, Michal (advisor)
The purpose of this study is to introduce the methods of the deconvolution and to programme some of them. For the simulation, the tissue homogeneity model and the model of arterial input fiction were used. These models were engaged as the test procedures with the aim of verify the functionality and utility of the Wiener filter, the Lucy-Richardson algorithm and the Singular value decomposition.

Business abroad
Bartoš, Michal ; Tyll, Ladislav (advisor) ; Eysseltová, Sylvie (referee)
The thesis is devoted to the issue of Czech-Russian trade relations and highlight Russia as a country suitable for Czech exporters. The aim of this thesis is to comprehensively analyze the business environment in Russia as a prior country for czech exporters, evaluate the potential of Russian market for Czech exporters, further characterize Czech-Russian business relations, describe the state institutions involved in promoting exports and provide comprehensive information to potential investors . The work is divided into three chapters. The first chapter analyzes Czech-Russian trade relations, with the emphasis on foreign trade.The second chapter deals with a comprehensive macroeconomic analysis of the RF with an outline of possible business opportunities for Czech exporters on the Russian market,a third chapter is devoted to pro-export policy of the Czech Republic.

Mezipodnikové srovnávání
Bartoš, Michal ; Vávrová, Hana (advisor) ; Doláková, Helena (referee)
Ve své diplomové práci jsem provedl mezipodnikové srovnávání společnosti Staropramen a.s. s konkurenčními společnostmi v odvětví pivovarnictví za období 2006 - 2008. Byly použity jak metody finanční analýzy (vertikální analýza účetních výkazů, analýza čistého pracovního kapitálu) tak i metody mezipodnikového srovnání: pořadí, bodovací, normované proměnné a vzdálenosti od fiktivního objektu.

acquirement and assessment of the empolyees in the ČSOB a.s. company
Bartoš, Michal ; Šikýř, Martin (advisor) ; Stříteský, Marek (referee)
In this bachelor thesis I analyze process of acquirement and assessment of the empolyees in the ČSOB a.s. company. I explained this process according to interview which i had in this company and according to opinions and experiences of the people, which are employed there. I also analyze the most utilized metods of this process, their advantages and disadvatages, and in the case of disadvantages, I suggest solutions. In the applied part I, in detail, analyze a job interview which i passed.
