Semantic differential as a method of detecting positioning and its dependence on contextual conditions
Petrová, Dominika ; Kincl, Tomáš (advisor) ; Novák, Michal (referee)
Thesis deals with measurement of positioning in marketing, specifically the method of semantic differential. The main objective of this work is to verify how it changes the semantic profile of selected wine samples tasted by young wine consumers in changing contextual conditions of this experiment. The experiment consists of two separate measurements, during which there is a change in the contextual conditions. The theoretical part is description of his positioning and measurement, which continuously follows the method of semantic differential, where he presented Seman-tick differential as a tool by which we can measure and record the positioning of his value by creating semantic profiles. The practical part explains the connection and answer research questions determined through experiment, where it was shown that the change in the contextual conditions tasted wine samples young wine consumers, changes the semantic profile of the wine samples.

Computational analysis of the dynamic behavior of the thrust bearings
Žatko, Miroslav ; Kos, Pavel (referee) ; Malenovský, Eduard (advisor)
This master´s thesis solves the problem of stationary viscous flow of incompressible fluids in thin layers of fluid film lubrication in fixed pad thrust bearings. The parametric computational model of oil domain was created for investigation the distribution of pressure, velocity and thermal fields together with the determination of the basic parameters as axial force, heating up and friction loss. Subsequently this model was applied for investigation influence of uneven bearing clearance. The problem task was solved by final volume method in Ansys CFX 12.0 software.

Agent-based Simulation of Processes in Medicine
Bošanský, Branislav
Process modelling has proven itself as a useful technique for capturing the work practice in companies. In this paper, we focus on its usage in the domain of medical care.We analyze the problem of the simulation of processes and present an approach based on agent-based simulations. We formally define an enhanced process language, the algorithm transforming these enhanced processes into the definition of agents’ behavior, and the architecture of the target multi-agent system simulating the modeled processes in some environment. The example of usage is given in the form of a critiquing expert system proposal that uses formalized medical guidelines as the knowledge base.

Dilemmas in Social Work with Job Seekers
FENCLOVÁ, Lucie
Thesis entitled "Dilemmas in Social Work with Job Seekers" deals with ethical dilemmas reflection of labour office employees with clients. In the text we encounter issues, which connect the practical implementation of the profession of labour office workers working with ethics. The thesis contains the terminology associated with the topic, defines the personality of the worker and his relationship with the client. It shows also list of clients with whom the workers meet and what dilemmas of these meetings may arise. The content of the work also deals with the basic concepts of professional ethics. Further, there are various forms of dilemmas defined in relation to working with clients. The thesis summarizes three specific ethical theories applicable to the issue of labour offices. Significant part is devoted to specific dilemmas with which workers encounter during their job with unemployed clients. Dilemmas are presented in the conclusion, in relation to the previous text supplemented by means of practical examples dealing with clients. It indicates possible reflection of the problem and behavior on the part of the worker. At the end of text there is presented a set of dilemmas that can bring negotiations with unemployed clients. The usability of this work is in the field of education in subjects related to ethical dilemmas and its solutions. It is also possible to extend the text for a doctoral thesis in the topic of dilemmas of employees from a specific department in comparison with other departments.

Data Security in Biomedicine
Horňáková, Anna
This thesis analyzes current state of use of biometrics in computer security. It provides an overview of the most commonly used anatomical-physiological and behavioral biometric identification methods. The result of the work will be a new set of methods, which allows reliable identification of the user in the most comfortable way. These new principles of data security will be used to enhance the protection of specialized health record. This will contribute to expansion of generally conceived EHR MUDR concept to other application areas.

Simulation of saltation motion using LBE based methods
Dolanský, Jindřich
The numerical model of the motion of the circular particle close to the bed in an open channel with a rugged bed based on the lattice Boltzmann method (LBM) is presented. The LBM is used as a DNS approach in which hydrodynamic forces are expressed as sum of contributions from fluid elements interacting with the moving particle. The corresponding numerical simulation for the saltation motion which represents a dominant mode of the bed load transport is developed. Flow is driven by the logarithmic velocity profile at the inlet of a two dimensional channel with a bed formed by semi-circles of variable radii in a bed of particles. Translational and rotational movements of the particle are induced by gravitational force on one hand, and by hydrodynamic forces on the other hand. The LBE (lattice Boltzmann equation) based simulation provides the opportunity to study the behavior of saltation motion in the moderate and high Reynolds number regimes. Most of the input parameters, including boundary conditions or flow conditions, are adjustable within a range of values. Stability issues of the simulation are considered and a resolution using a combination of different LBE models and the extension of computational resources is proposed. Finally, an enhancement of the simulation for more complex processes is suggested.

Some comments on frequency selective excitation in newly proposed MRSI sequences
Starčuk jr., Zenon ; Horký, Jaroslav ; Starčuk, Zenon ; Mlynárik, V. ; Gruber, S. ; Moser, E.
In many pathologies it is desirable to compare the metabolism inside a lesion, near the lesion, and in healthy tissue. The diagnostic value of MRS is enhanced by spectroscopic imaging (MRSI), permitting the simultaneous acquisition of spatially resolved spectra. In this way, assessing metabolic information about different brain regions within a single examination is possible. As with all in vivo spectroscopy, low signal-to-noise ratio (SNR) is the fundamental limiting factor in MRSI due to very low concentrations of metabolites of interest. Proton spectroscopic imaging, however, offers additional technical challenges as compared to single-voxel techniques, especially if acquisition of short echo time (TE<30 ms) is required. Critical to the success of proton MRSI studies of the human brain is the elimination of the very intense water and lipid signals arising from outside the volume of interest (VOI). Water suppression in MRSI can be very problematic in MRSI, in which the achievable degree of water suppression is limited by B.sub.0./sub. and B.sub.1./sub. inhomogeneities and water T.sub.1./sub. variations, invariably present throughout the larger VOIs. Suppression of liquid signals (from bone marrow and subcutaneous fat) is often severely complicated due to the fact that their relaxation behavior differs substantially from that of water. One of the basic approaches used to reduce the undesired contamination if the MRSI signals of interest consists in the use of the STEAM or PRESS selective excitation of the VOI. Both STEAM and PRESS techniques suffer from some drawbacks. STEAM reduces the sensitivity of measurement, PRESS has higher RF power requirements.
