The goal of this masters thesis is focused on segmentation of the organic food market in the Czech Republic based on analysis of similarities or differences among consumers in Czech organic food market and also find out who is a typical organic food consumer. The thesis is divided into three parts, the theoretical, the methodological and the practical part. Process of the market segmentation, methods and approaches of the segmentation, the basic concepts and legislation on the matter are described in the theoretical part. Furthermore, mapping the situation of the contemporary state of the Czech organic food market. Marketing research is introduced in methodological part of the thesis. The practical part includes market segmentation by using secondary data MML - TGI (with Data Analyzer software) and primary data from quantitative research (with SPSS software). Variables were reduced to the four factors by using factor analysis. Then consumers were put into five clusters based on cluster analysis. Segments were characterized in detail using a general analysis, contingency tables, MCART analysis and multivariate statistical methods. Finally, there were elaborated appropriate marketing recommendations for the individual segments to effective marketing communication with them.

Drdla, Adam ; Vančura, Jan (referee) ; Svída, David (advisor)
The aim of this thesis is to provide research into turbocharger regulation, and analyze the force load of vanes in the VNT mechanism of Garrett turbocharger by CFD simulation. In the thesis there is one model with two different mesh densities. It describes the relevance of supercharging vehicle engines and the kinds of supercharging aggregates in the introduction. Then, the thesis is divided into two chapters. The first chapter provides research, describing primary principle of supercharging, turbocharger construction and kinds of air regulation. The practical part of the thesis solves the force load of VNT mechanisms. It was necessary to optimalize the 3D Garrett turbocharger model, create two meshes with different element densities, specify boundary conditions and analyse the results of both cases. A general description of solved problems, comparison of results of force load vanes and propose simplifying and verifying the CFD calculation are included in the conclusion.

Ultrasonographic evaluation of cardiovascular abnormalities in patients with Fabry disease
Paleček, Tomáš ; Bultas, Jan (advisor) ; Pudil, Radek (referee) ; Kittnar, Otomar (referee)
Fabry disease is an X-linked glycosphingolipid storage disorder caused by deficient activity of the lysosomal enzyme α-galactosidase A. This leads to progressive intracellular accumulation of neutral glycosphingolipids, mainly globotriaosylceramide. Besides various extracardiac disease-related abnormalities, cardiovascular involvement represents a typical manifestation of Fabry disease. The primary underlying mechanism relies on pathological substrate accumulation in cardiomyocytes, conduction system cells, valvular fibroblasts, endothelial cells and vascular smooth muscle cells. The development of cardiac and vascular hypertrophy represents a characteristic cardiovascular feature of Fabry disease. The aim of our studies was to describe in detail cardiovascular abnormalities in patients with Fabry disease using ultrasonography, which currently represents basic noninvasive imaging modality in cardiology. We focused on structural and functional abnormalities of ventricles, valvular apparatus and their relationship to vascular involvement expressed on common carotid arteries. We also compared the diagnostic accuracy of the two novel echocardiographic methods used for the left ventricular diastolic function assessment. The possible existence of circulating proliferative factor, which might be associated with...

STRAIN ENGINEERING OF THE ELECTRONIC STRUCTURE OF 2D MATERIALS
del Corro, Elena ; Peňa-Alvarez, M. ; Morales-García, A. ; Bouša, Milan ; Řáhová, Jaroslava ; Kavan, Ladislav ; Kalbáč, Martin ; Frank, Otakar
The research on graphene has attracted much attention since its first successful preparation in 2004. It possesses many unique properties, such as an extreme stiffness and strength, high electron mobility, ballistic transport even at room temperature, superior thermal conductivity and many others. The affection for graphene was followed swiftly by a keen interest in other two dimensional materials like transition metal dichalcogenides. As has been predicted and in part proven experimentally, the electronic properties of these materials can be modified by various means. The most common ones include covalent or non-covalent chemistry, electrochemical, gate or atomic doping, or quantum confinement. None of these methods has proven universal enough in terms of the devices' characteristics or scalability. However, another approach is known mechanical strain/stress, but experiments in that direction are scarce, in spite of their high promises.\nThe primary challenge consists in the understanding of the mechanical properties of 2D materials and in the ability to quantify the lattice deformation. Several techniques can be then used to apply strain to the specimens and thus to induce changes in their electronic structure. We will review their basic concepts and some of the examples so far documented experimentally and/or theoretically.

Methods of carbon dioxide emission reduction
Mališ, Jan ; Kermes, Vít (referee) ; Bébar, Ladislav (advisor)
Master's Thesis is focused on production of CO2 from fossil fuels combustion and the methods of CO2 emission from fossil fuels combustion reduction, resp. pre-combustion and post-combustion separation of CO2. Recapitulation of world consumption of primary energetic resources and carbon dioxide production as a result of theirs combustion in years 1971 - 2006 was made using a number of information sources. Whilst combustion o fossil fuel is related with production of CO2, calculation of emission rate of CO2 from fossil fuels (natural gas, crude oil and coal) was demonstrated. The Case Study of energy and material balances of gas turbine cycle with synthesis of methane from CO2 and from hydrogen which is produced in water splitting was made, using CHEMCAD software.

Oscillatory Power Generator Base on Mechanical Resonant Element
Mihalík, Vlastimil ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
This work deals with the power supply of wireless sensors. When using a wireless sensor is desirable application of alternative energy sources, because the primary cells or batteries may reduce the extent or length of service of the sensor itself. Ambient energy can be used as a suitable alternative source. This energy must be in an appropriate form, which allows its conversion to electric energy. These appropriate, already used types include: solar en., temperature gradient en., en. of flowing liquids, vibration, etc. The advantage of vibrations is its presence in almost all mechanical systems. One of the possibilities for using the vibration of machine systems for power supply wireless sensors is using the vibration power generator with oscillating component. The generator must be designed so that its resonance frequency coincides with the frequency of vibration in the machine system. This method can be used only if the machinery system vibrations at least partially constant. Another option is to use the vibrations caused by, for example, transit transport, or different step acting factor. In this case, it is desirable that the generator is designed with variable resonant frequency, which can partly be achieved, for example, integrating several oscillating component in the body of generator. After the general analysis of the problem, graduation theses will be concerned with the possibility of use of energy from the short damped oscillation and step impulse. Focusing on a proposal of multi-element structures.
