Image similarity measurement using points of interest
Jelínek, Ondřej ; Uher, Václav (referee) ; Burget, Radim (advisor)
This paper presents a new object detection method. The method is based on keypoints analysis and their parameters. Computed parameters are used for building a decision model using machine learning methods. The model is able to detect object in the picture based on input data and compares its similarity to the chosen example. The new method is described in detail, its accuracy is evaluated and this accuracy is compared to other existing detectors. The new method’s detection ability is by more than 40% better than detection ability of detectors like SURF. In order to understand the object detection this paper describes the process step by step including popular algorithms designed for specific roles in each step.

The possibilities of firm financing and insurance during the international market expansion
OCHOTNÁ, Jana
Nowadays, we may say that entrepreneurial activities include, among others, efforts aimed at searching and discovering new opportunities on the markets, the ability to make use of new chances and undertake any risks that may result to economic success as well as failure. The modern world is the world of constant changes and uncertainties. In such a world, those will win who will learn how to make use not only of opportunities on the market, but many times also the threats that uncertainty may bring along. The main aim was the analysis of the finance and insurance situation of the firm entering the international market. The other aim was the analysis of insurance and finance market and the concept of the best possibility for the firm. The result of this analytic part was the prediction, that the firm is able to enter the international market with direct business method, but first of all there is necessary to introduce it{\crq}s production, prices and the whole firm on the websites. During the analysis the firm has to specify it{\crq}s strategy and aims, makes calculations and decides of which insurance will be siutable for it. The next step was the decision of using the export financing, If it decides to finance the export, it{\crq}s necessary to chooze, if it will use the financing by private or state grant. For the firm the using of exports buyer or supplier credit will be two acceptably methods. The credit insurance by the state or private institutions is the other step to enter the international market. There are various kinds of other insurance (e.g. cargo, casco insuranc or the payment risk insurance).

Study of biological activity of isolated alkaloids from Corydalis cava (Fumariaceae)
Chlebek, Jakub ; Opletal, Lubomír (advisor) ; Drašar, Pavel (referee) ; Kuča, Kamil (referee)
Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Botany and Ecology Candidate: Mgr. Jakub Chlebek Supervisor: Doc. RNDr. Lubomír Opletal, CSc. Title of Doctoral Thesis: Study of biological activity of isolated alkaloids from Corydalis cava (Fumariaceae). Key words: Corydalis cava, isoquinoline alkaloids, DPPH, AChE, BuChE, BACE1, IMER. Tubers of Corydalis cava were selected on the basis of bio-guided spectrophotometric Ellman's method as a source of isoquinoline alkaloids for study of their selected biological activities. The tubers of Corydalis cava were extracted with ethanol and the mixture of summary tertiary alkaloids (fraction A) was fractionated in silica gel chromatography column using step gradient elution with hexane, chloroform and ethanol. Repeated column chromatography, preparative TLC and crystallization led to the isolation of fifteen isoquinoline alkaloids. The chemical structures of isolated compounds were determined on the basis of spectroscopic techniques and by comparison with literature data. Isolated alkaloids were tested on ability to inhibit AChE, serum BuChE (IC50), BACE1 and for its free-radical scavenging activity (EC50). The cholinesterase inhibitory activity was determined in vitro by modified spectrophotometric Ellman's...

The collaboration of the Catholic Church and priests with the socialist regime of the GDR in theological and ethical reflection
Buss, Gregor ; Rethmann, Albert-Peter (advisor) ; Ovečka, Libor (referee) ; Šrajer, Jindřich (referee)
The doctoral thesis tries to reflect the collaboration of Catholic priests with the Ministry for State Security (= Ministerium für Staatssicherheit; MfS or Stasi) in the former GDR from a theological perspective. This is done in two steps. The first part of the thesis illustrates the historical background. This includes an introduction into the history, ideology and working methods of the Stasi. The main goal, however, is to give an overview of the amount and charakter of the collaboration of Catholic priests. The first part ends with a typology of the different motives and reasons for cooperating with the Stasi. In the second part the problem of collaboration is reflected from an ethical perspective. It is not intended to evaluate individual cases, but to elaborate criteria for the evaluation of individual cases. The guiding assumption is that the cooperation with state security ether arose from a lack of willing, a lack of ability, or a lack of cognition. The priests were therefore either limited in their moral motivation, their freedom or their cognitive competence. To what extent these limitations were caused by the priests themselves or by the surrounding circumstances, can be regarded as a key question when it comes to evaluating cases of collaboration.

Financial analysis of LDM, Ltd.
Čečotka, Miroslav ; Boukal, Petr (advisor) ; Eisler, Jan (referee)
Dissertation is divided into two major parts -- the former is dedicated to theoretic approches to financial analysis, the latter to application of previously gained knowledge in a company. The introduction of work is dedicated to the purpose, usage and approaches to financial analysis with respect to various users of the analysis output. Moreover the document in a very detailed way deals with sources of data for financial analysis processing including weak points and their reflection in ability of calculated indicators of the financial analysis (FA) to give evidence. The most attention is of cource paid to individual steps in thorough financial analysis -- ie. vertical and horizontal analysis of statements and calculations of proportionate indicators including indicator examples from separate spheres of the analysis. Systems of indicators -- parallel but mainly pyramidal, concretely Du-pont's model is used. Dissertation thereinafter is devoted to another indicators that are useful for appreciation of the financial company health, concretely Altman's model, Kralicek's quicktest, Index IN and economic value added (EVA indicator). Comparision with branch of activity that is the company work in is a part of dissertation too. In the second part of the work, a specific company is being analysed -- in successive steps meant in the previous part. After statement analysis and calculations of proportionate indicators, I evaluate to what degree the company is successful. Simultaneously the results can indicate that outputs from the well elaborated financial analysis are of a very useful source of information for company management.

Optimization of Presentation with Regard to Maintaining the Auditors Attention and Enhancing the Ability to Keep the Presented Content in Mind
Hrkal, Marek ; Pauknerová, Daniela (advisor) ; Kočí, Ondřej (referee)
Presentation became an important communication phenomenon of today. However, its quick onset caused that presenting has been considered as an ability without theoretical fundamentals. This diploma thesis makes an effort to convince the readers about the opposite by connecting practical presentation procedures with theoretical knowledge based on literature concerned with psychology and social communication. The emphasis is put especially on application of the theory of perception, attention and memory. In the application part of this theses all stages of preparing and delivering a presentation are analyzed step by step. Belonging to the empirical part, an evaluation of presenters was carried out. For this very purpose an evaluation sheet was created as a formalized methodical tool. This thesis is usable by any communicator who wants to understand the theoretical phenomena on which presentation is based.

Non-specific preparation of figure skaters (5-14 years of age) during preparation period
Pavlovičová, Klára ; Perič, Tomáš (advisor) ; Prajerová, Květa (referee)
Title: Non-specific preparation of figure skaters (5-14 years of age) during preparation period Purpose of paper: In the diploma paper I am going to focus on the issue of non-specific preparation of figure skaters. I would like to point out the importance of establishing a wide basis of agility abilities in children (from the ages of 5 to 14) during training season. The purpose of this work is to create a model of non-specific preparation of children, which emphasizes the main non-specific agility abilities for later peak performance training of figure skaters. These include balance, coordination, flexibility, endurance, speed, and strength. These qualifications determine the measure of exact execution of specific elements on the ice (jumps, step variations, pirouettes, and spirals). It is clear that these agility abilities are interconnected in a direct and indirect way. By creating a coherent training approach, these connections can be discovered, named, and included in the preparation structure. The methods: The method of literature research was utilized for this work. The result: The result should be a proposal of a coherent training approach of non-specific preparation of figure skaters (from the ages of 5 to 14) during training season. KEY WORDS: Figure skating, preparation structure:...
