The Elliott wave principle and its significance in technical analysis
Gorol, Tomáš ; Blaheta, Petr (advisor)
The main goal of the thesis is to introduce the reader to the Elliott wave principle as a part of technical analysis, its fundamentals and exploitation in contemporary markets. At the beginning of the thesis basic tenets of technical analysis and the characteristics of common trading tools are described. The next chapter determines the fundamentals of the Elliott wave principle, its rules for trading, possible risks and disadvantages. The reader is also introduced to the mathematical background, exploitation in trading and other factors which influence the Elliott waves. The conclusion of the thesis is directed to application of the Elliott waves on real markets in combination with other tools of technical analysis and its evaluation.

Eliptic indexing of multidimensional databases
Danko, Ondrej ; Hoksza, David (referee) ; Skopal, Tomáš (advisor)
In this work variation of R-tree, which hierarchically partition indexed space using minimum volume covering ellipsoids (MVCE) instead of usually used minimum bounding rectangles, is presented. Main aspects, which determine R-tree index structure performance, are studied from the available resources at the beginning. Base on this studies "e-Rtree" (ellipsoid R-tree) is designed. Afterward algorithms of MVCE construction are carefully analyzed, as the choice of the algorithm is crucial for the efficiency of indexing and retrieval. At the end of the work, eR-tree implementation over ATOM framework is presented along with experiments done on synthetic and real data sets.

Mathematical Analysis and Numerical Computation of Volume-Constrained Evolutionary Problems Involving Free Boundaries
Švadlenka, Karel ; Feistauer, Miloslav (advisor) ; Křížek, Michal (referee) ; Knobloch, Petr (referee)
The object of study of the present thesis are evolutionary problems satisfying volume preservation condition, i.e., problems whose solution have a constant value of the integral of their graph. In particular, the following types of problems with volume constraint are dealt with: parabolic problem (heat-type), hyperbolic problem (wave-type), parabolic free-boundary problem (heat-type with obstacle) and hyperbolic free-boundary problem (degenerate wave-type with obstacle). The key points are design of equations, proof of existence of weak solutions to them and development of numerical methods and algorithms for such problems. The main tool in both the theoretical analysis and the numerical computation is the discrete Morse flow, a variational method consisting in discretizing time and stating a minimization problem on each time-level. The volume constraint appears in the equation as a nonlocal nonlinear Lagrange multiplier but it can be handled elegantly in discrete Morse flow method by restraining the set of admissible functions for minimization. The theory is illustrated with results of numerical experiments.

Real Estate IPOs. Theory and Analysis focused on the Polish market
Makovec, Martin ; Marek, Petr (advisor) ; Musílek, Petr (referee) ; Fárek, Jiří (referee)
The doctoral thesis examines real estate IPOs and consists of a theoretical part and an empirical part focused on Polish market. The theoretical part offers an overview of theories concerning IPO and the three well-known phenomena related to initial public offerings, i.e. short term underpricing, long term overpricing and occurrence of IPO in waves. In case of short term underpricing and long term overpricing the theories presented are namely the theories based on information asymmetry, institutional theories, agency theories and behavioral theories. In case of IPO waves the theories presented are capital demand hypothesis, information asymmetry hypothesis and investor sentiment hypothesis. Some of the theories, namely the information asymmetry theory, are then applied to the specific case of real estate IPOs. The starting-point for the empirical part is an assumption that valuation of real estate IPOs is less complex than valuation of other companies and therefore information asymmetry among issuers and investors should be presented to a lesser extent. The valuation of real estate IPOs via their Net Asset Value ("NAV") requires less inputs and parameters compared to the corporate valuations with sophisticated financial modelling of the generators of value. Such lower complexity of valuation should be reflected in better ability of the investors to value the emission of the real estate company shares. Subsequently a lower underpricing of the IPOs should be reached and worse long term performance of the IPOs should be eliminated. In relation to the occurrence of the real estate IPOs the existence of IPO waves is assumed. In addition, subject to the assumption that the economical cycles on the real estate markets are longer than on the other markets, longer periods with higher occurrence of IPOs and longer periods with lower or no occurrence of IPOs are expected. The analysis investigates real estate IPOs which in USA means IPOs of so called REIT -- "Real Estate Investment Trusts". REIT is a special institute that guarantees to the companies that adopt this statute, obviously upon meeting several conditions, exemption from the corporate income tax. The REIT are regularly dividend into so called equity REIT, investing in real properties, mortgage REIT, investing in mortgage loans and hybrid REIT, investing in both. With regard to the fact that the analogy of the REIT institute does not exist in Poland, the analysis investigates real estate companies of similar characteristics to the equity REIT. The analyzed markets are polish capital market and real estate market, which both could have been until very recently called emerging markets. It is assumed that the emerging market environment could have impacted the result of the analysis significantly. The analyzed period is basically identical with the modern period of functioning of the Warsaw Stock Exchange, meaning years 1992 -- 2012. The size of the analyzed sample has reached limited but acceptable size of 22 titles. The subject of the analysis are all three major phenomena related to IPOs -- IPO waves, initial underpricing and long term underperformance. The analysis confirmed occurence of a real estate IPO wave on the Polish market in the year 2007 as the market was featuring characteristics of a "hot" market and investors were overly optimistic about real estate titles. In addition, the analysis supported the assumption of a positive correlation between IPO occurence and GDP growth and also between IPO occurence and the volume of real estate investment on the market. Further, the hypothesis test confirmed existence of initial underpricing in case of the real estate IPOs, however to a smaller extent compared to the other corporate IPOs. Subsequent tests were looking to find correlation between the rate of initial underpricing and several factors of the emission such as size, segment of the real estate market etc. In case of long term underperformance, based on the gather evidence, the test could not reject the null hypothesis about the same of better performance of the real estate IPOs compared to the WIG stock indice. Long term underperfomance was thus not confirmed in case of real estate IPOs. Subsequent tests were again investigating impact of several characteristics of the offerings on their long term performance.

Standing-wave-grazing-incidence x-ray diffraction from polycrysrtalline multilayers
Krčmář, jan
Title: Standing-wave-grazing-incidence x-ray diffraction from polycrystalline multilayers Author: Jan Krčmář Department: Institute of Condensed Matter Physics, Masaryk University Supervisor: prof. RNDr. Václav Holý, CSc. Supervisor's e-mail address: holy@mag.mff.cuni.cz Abstract: In this dissertation we present a new method, which uses the concept of x-ray standing wave in the grazing-incidence geometry, in which both the incidence and exit angles αi,f are close to the critical angle αc of total external reflection. If the angle of incidence αi of the primary x-ray wave onto a periodic multilayer is close to αc or to a "Bragg-like" maximum on the reflectivity curve, the interference of the transmitted and reflected waves creates a standing wave pattern in the multilayer volume, the period of which equals the multilayer period. If the multilayer contains crystalline grains (crystallites), the intensity of diffraction from these crystallites depends on the mutual position of the crystallites and the antinodes of the standing wave. Similarly, the wave diffracted by the crystallites is reflected from the multilayer interfaces, which results in a standing wave pattern as well. The standing wave pattern is shifted by changing αi or αf so that from the measured dependence of the diffracted intensity on αi,f it is...

New trends in the automotive industry
Martan, David ; Smrčka, Luboš (advisor) ; Zámečník, Petr (referee)
This thesis describes new trends in the automotive industry. It investigates how these trends altered the automotive market and industry and what are the reasons of it. The thesis then ascertains an impact on the new cars business, in which stress is put on new technologies and automotive market development in the world, with emphasis on the Czech Republic within the crisis period. The thesis follows 2 trend groups, namely the trends that already appear for a longer time as well as the quite new trends influencing substantially the automotive market. The first named group deals with the technological innovations as well as for example with the problem concerning car factories model families expanding with the aim to maximize volume of sale; problems of the car new models safety and performance is another topic of this thesis. As another important topic of this group diesel drive phenomenon problems in the European Union can be taken into account as well as additional burden of taxation for cars with higher fuel consumption connected with it. A significant part of the second group comprises financial crisis development and impact on the new cars sale in a given period. In addition to it, it describes quite new trends, e.g. engine capacity decreasing with the use of supercharged engines (downsizing), coming wave of SUV cars and a phenomenon of four-wheel drive cars. In the final part of this diploma paper problems are analyzed and finally hybrid cars development as well.

Hemodynamics in the early stages of the critical illness and in the perioperative setting
Beneš, Jan ; Kasal, Eduard (advisor) ; Málek, Jiří (referee) ; Kroužecký, Aleš (referee) ; Adamus, Milan (referee)
Beneš J.: HEMODYNAMIKA V ČASNÉ FÁZI KRITICKÝCH STAVŮ A PERIOPERAČNÍ MEDICÍNĚ - Využití méně invazivních monitorovacích prostředků k cílené hemodynamické péči ABSTRACT Hemodynamic instability occurs very often in critically ill patients and during the perioperative period. Insufficiency in the preload, contractility and afterload contribute in major part to this phenomenon. Hemodynamic monitoring allows clinicians to recognize and to intervene early the underlying cause. Due to new technologies development in recent years it is possible to provide continuous monitoring of hemodynamic parameters with diminished invasivity. Hemodynamic optimization and goal directed therapy show treatment benefit in some groups of critically ill patients and mainly during the perioperative period. Aim of hemodynamic optimizations is to attain the best obtainable hemodynamic conditions with use of fluid loading and inotropic support. In many studies in recent years goal-directed therapy was associated with morbidity and mortality reduction. According to the results of our clinical research hemodynamic optimization using stroke volume variation and minimally invasive device based on the pressure wave analysis is feasible and show the same results as other works with more invasive devices. Key words Hemodynamic monitoring,...
