This Master’s thesis is dedicated to cavitation erosion of a material surface. First part of thesis describes basic principle of cavitation and its erosion consequences of solid objects. There are mentioned basic cavitation models used in CFD software. Second part incorporate concept design and numerical calculation of critical shape in reference to highest intensity of cavitation erosion at flow area. Last part of thesis is experimental and it is focused on cavitation erosion at flow area due to critical shapes from numerical calculation.

This thesis deals with investment analysis tools focused on real estate. Thesis describes investment instruments in the Czech Republic and abroad. The practical part is devoted to equity indices, which focus on Central and Eastern Europe. The thesis describes the possible causes of the financial bubble in real estate stock markets and the impact of financial crisis on the evolution of these equities.

Economic bubbles are playing an increasingly significant role in the current global economy. We believe these bubbles are to a certain extent dominating the real economy, and, therefore, research based on this specific economic phenomenon is becoming increasingly popular and important. The focus of this master's thesis is based upon analysis of stock price bubbles. This thesis contains author analyzed historical cases representative of stock price bubbles; summarizations of their traditional features; common factors causing their formation; and reasons leading to their bursting. Solutions to the dilemma of stock price bubbles are discussed in depth, and emphasis is placed upon clearly deciphering different theoretical approaches regarding this phenomenon-not only from the efficient market hypothesis viewpoint but also from the perspective of behavioral finance. The research contains testing and measuring methodologies of stock price bubbles, and the author's view concerning them is strongly supported by the results within the empirical data-testing chapter. Upon reading, one can expect to achieve a basic overview of this forefront science.

This thesis studies bubbles in the U.S. stock market and how they are influenced by monetary policy pursued by the FED. Using Kalman filtering, the log-real price of S&P 500 is decomposed into a market-fundamentals component and a bubble component. The market-fundamentals component depends on the expected future dividends and the required rate of return, while the bubble component is treated as an unobserved state vector in the state-space model. The results suggest that, mainly in recent decades, the bubble has accounted for a substantial portion of S&P 500 price dynamics and might have played a significant role during major bull and bear markets. The innovation of this thesis is that it goes one step further and investigates the effects of monetary policy on both estimated components of S&P 500. For this purpose, the block- restriction VAR model is employed. The findings indicate that the decreasing interest rates have a significant short-term positive effect on the market-fundamentals component but not on the bubble. On the other hand, quantitative easing seems to have a positive effect on the bubble but not on the market-fundamentals component. Finally, the results suggest that the FED has not been successful at distinguishing between stock price movements due to fundamentals or the price misalignment.

The thesis addresses the instabilities in stock markets in the USA. There are many factors that may increase the price volatility, or even cause a panic. During these turbulent times investors can seek shelter in investment safe havens that allow protecting their portfolio against significant financial losses. The focus is put on identifying the situations where it is appropriate to use the safe havens and how to properly time all transactions. Historical insight, events study and investigating economic cycles are the integral part of the work.

The aim of this thesis is to analyse the research area of omitted intangible assets from the balance sheet and consider rewards of their potential recognition in the statement of financial position. The theoretical part provides the reader with the current regulation in force and compares it to the regulation prior the standardization and convergence process. The empirical part focuses on valuation of equity of three companies from the pharmaceutical industry based on the model pursued by American professor Stephen Penman. The values obtained are subsequently compared to market prices which are believed to reflect also the possession of omitted intangible assets. Differences identified speak in favour of potential recognition, however these are believed to be marginal comparing to probable inherent risks, which include, inter alia, stock market run-ups and earnings management.

This master thesis is engaged in problematics of creation and compensation of geometric distortions in 1D agarose electrophoresis. This master thesis analyze the problematics of cause of these distortions and summarize the theory needed for compensation of these distortions. Based on acquired theory and created electrophoretic phantoms, the master thesis contains several suggestions for compensation of incurred distortions. These suggestions are recreated into functions, which are connected into a functional user interface for gel image analysis and geometric distortions compensation.
