Model Consideration for Blind Source Separation of Medical Image Sequences
Tichý, Ondřej
The problem of functional analysis of medical image sequences is studied. The obtained images are assumed to be a superposition of images of underlying biological organs. This is commonly modeled as a Factor Analysis (FA) model. However, this model alone allows for biologically impossible solutions. Therefore, we seek additional biologically motivated assumptions that can be incorporated into the model to yield better solutions. In this paper, we review additional assumptions such as convolution of time activity, regions of interest selection, and noise analysis. All these assumptions can be incorporated into the FA model and their parameters estimated by the Variation Bayes estimation procedure. We compare these assumptions and discuss their influence on the resulting decomposition from diagnostic point of view. The algorithms are tested and demonstrated on real data from renal scintigraphy; however, the methodology can be used in any other imaging modality.

Lam Van, Duyet ; Vodňanský, Daniel (advisor) ; Zumr, Jiří (referee)
Lack of knowledge of the Czech language means a serious problem for foreigners living in the Czech Republic. Czech language should help them in communication, business, studying, but for some people it is also the necessary condition for obtaining a permanent residence. The aim of this bachelor thesis is to design and implement a web application that should serve as a source of learning the Czech language for foreigners. To achieve this goal, the thesis first deals with the analysis of the existing solutions for Czech language e-learning. A design of a web application, user interface and the structure of the database model is suggested based on the finishing analysis. After designing the web application, its development follows, in which the client/server architecture and selected web technologies including Laravel Framework, jQuery and MySQL database system are used. The output of this work is a detailed web-based application that provides an access to educational lessons, instructions and exercises for users, who need to improve in Czech language. They can test their knowledge and determine their skill level.

Analysis and design of intranet structure
Novák, Miroslav ; Pour, Jan (advisor) ; Šedivá, Zuzana (referee)
Nowadays, Intranet is an inseparable part of every company, notwithstanding of their size or field of activity. Both, in my work and personal life, I often come across different intranets that usually do not get a positive response. But they usually have the same source of the problem, which is based on their wrong structure. This is why is chose this topic for my thesis. The goal of my thesis is to perform an analysis of an existing intranet of a particular company and subsequently create a design of the intranet new structure using the card-sorting method. This thesis primarily represents a generalized method of how to proceed during such realization and which areas to look into. Theoretical part of this thesis covers the topics of information architecture and also the term intranet itself, where the most frequent issues I came across in the intranets are pointed out. Practical part covers the analysis itself, where I focus on the structure of the existing intranet, categorization of its content, connections with other systems, customization, permission management, surveys of contentment, and intranet usage. The analysis is performed manually by scanning through the existing intranet of the company, since other methods or approaches could not be applied due to technical limitations or insufficient permis-sions. Based on the outputs of the analysis, web categorizations and the card-sorting method, a design of a structure of the new intranet has been proposed. The design itself is a demonstration of the method how to approach the new intranet design.

The way of consumerism in the interwar Czechoslovakia nn the example of consumption of coffee, cocoa, chocolate and tea.
Syrová, Tereza ; Jakubec, Ivan (advisor) ; Jančík, Drahomír (referee) ; Štemberk, Jan (referee)
Dissertation thesis discusses the consumption of cocoa, coffee, tea and chocolate in the interwar period in the Czechoslovakia. On the basis of statistical data and examination of archival sources comes with the definition of the middle classes of the population, which those commodities consumed. The thesis shows the distribution of consumption of commodities based on the survey in blue-collar and white-collar families. Furthermore provides insight into the lives of families, distribution of their spending and the size of income. It refers to the representation of cocoa, coffee, tea and chocolate in the consumer basket and shows the elasticity of the mentioned commodities. For the central part of the research of the dissertation thesis chose the Czech territory only, because here were without difficulty accessible data sources. The Dissertation thesis clarifies the causes of consuming cocoa, coffee, tea and chocolate and concludes that each was consumed from another purpose, which resulted status of these commodities. Tea consumption has been designed especially for the higher classes of the population, chocolate bought mostly white-collar family, but over twenties speared consumption of chocolate products also among the middle and lower classes into the population. The chocolate products were subject to early 20s of the luxury tax. Cocoa was used in connection with cooking and baking, but families didnt use this product frequently. Coffee drank all layers of the population, but consumption was based on the social status of the consumer. Very frequently families consume rye coffee and chicory coffee. Dissertation thesis also highlights the regional differences between the classes, which were further intensified. Thesis examines in detail the amount of the duties of the commodity, which in the interwar period varied widely, and concludes that the duty to disproportionately increase the price of products and made it impossible for consumers to buy more of cocoa, coffee, tea and chocolate.

Řízení IS/ICT se zaměřením na sourcing služeb informačního systému
Šebesta, Michal ; Voříšek, Jiří (advisor) ; Havlíček, Zdeněk (referee) ; Příklenk, Oldřich (referee) ; Král, Jaroslav (referee)
Research on outsourcing has been around for several decades, while recent evolution in the information systems discipline towards ICT service commoditization significantly changes the context of decision-making. Services that are available on-demand via the Internet allow organizations implementing functions they demand in a fraction of time. This trend represents a chance for organizations seeking to use advanced ICT services without a need of major investments. Problem is the current lack of guidelines and tools for managing ICT services and their outsourcing. Given the trends on the ICT service market, it is expected that much of the IT management in the future will encompass the ICT services and utilize service-level structures. Methods currently available are either too broad or encompass only small part of the whole problem. Ad-hoc or unsound decisions in this area might cause major complications in terms of quality, usability, integration, and consequently influence total cost of organizational IT. Organizations need to either revise existing models or propose and implement completely new models to manage their IS/ICT. This thesis deals with the management of IS/ICT with focus on the ICT services outsourcing. It discusses available sourcing models in the literature and links them to the various interconnected areas. Based on these areas, it presents an integrated view on IT outsourcing strategies. Most importantly the thesis proposes an original concept for decision-making about outsourcing of ICT services named the SOURCER framework. This approach utilizes the presented outsourcing strategies, and introduces a complex methodology and decision-making criteria that will assist organizations with selection of ICT services in order to maintain and manage a most suitable ICT service portfolio. The decision-making is based on four essential viewpoints: function, costs, time, and quality. These viewpoints are discussed, individually analyzed, and serve as a basis for further research. The whole framework is developed and validated according to Design Science Research Methodology (DSRM). Individual components are evaluated using a survey among a group of selected IT managers. Proof of concept is then established by a case study on framework use in a real organization. This case study covers strategy specification, business--IT alignment, specifying service architecture and its interconnections, outsourcing, and management of the ICT service portfolio.

Růst Mycobacterium smegmatis na agarovém médiu a agarovém médiu pokrytém celofánovou folií - morfologická a proteomová studie
Ramaniuk, Volha ; Weiser, Jaroslav (advisor) ; Beranová, Jana (referee)
Biofilm formation is one of the most common bacterial survival strategies. Majority of bacterial species are able to form these three-dimensional structures, including pathogens like Mycobacterium tuberculosis. Representatives of Mycobacterium genus widely occur in the nature, although they can cause serious problems when they appear in medical equipment and artificial replacements of the human body. Non-pathogenic Mycobacterium smegmatis mc2 155 was used as a model organism in our experiments. We investigated morphology of the three- and six-day-old colonies (in fact biofilms) on agar and agar covered with cellophane using Stereo microscope and Scanning Electron Microscope. We found that a type of surface as well as a carbon source has a great influence on the morphology of the M. smegmatis colonies. We isolated proteomes from the agar and cellophane cultures and from planktonic culture. Two-dimensional electrophoresis was used as the main proteomic method. Proteomic data were analyzed using PDQuest software. Then the sets of proteins detected by qualitative and quantitative analyses were compared using Venn diagrams. As a result, we recognized 7 unique proteins that might be specific for recognition and adhesion of bacteria to the cellophane, no unique protein in agar proteome and 46 unique...

World Trade in Crude Oil
Benešová, Nela ; Čajka, Radek (advisor) ; Bolotov, Ilya (referee)
This master´s thesis deals with trade with crude oil and its impact on the world economy. Everyone, who wants to start to trade with crude oil, should find out basic terminology and information about crude oil that is characterized in the first chapter. The hunt for oil started many years ago, therefore the history is also mentioned in this master´s thesis. The second chapter focuses on the world trade with crude oil. Territorial structure and trade flows are described in this part of the master´s thesis. Nevertheless, the crude oil also has an impact on the world economy and economies of single states. The third chapter analyses states, where the inhabitants live beyond means of people from other countries but these states are so depended on crude oil that if this trade stopped, these countries would go bankrupt. However, there are also exceptions. Even though, there are states that have huge sources of crude oil, they still have to deal with financial problems. The forth chapter characterizes the trade with crude oil of the Czech Republic because it is a net importer of crude oil and the last chapter focuses on new trends in crude oil such as shale oil and trading at a crude oil market.
