This Thesis deals with the convergence of European states and identifies the influence of the European union enlargement in 2014 on the course of convergence. Both real and price convergences are analyzed by using beta convergence and sigma convergence concepts. The Balassa Samuelson effect is tested as well. The Balassa Samuelson effect explains the existence of price convergence and also indicates the relationship between real and price variables. The existence of real and price convergence was verified for the whole period from 1995 to 2013. During 2004 the integration of European states was strengthened, which was significant for real convergence because the speed of convergence was positively influenced. As for the price convergence, the year 2004 was insignificant as the break point. Despite a similar course of both convergences, price convergence was more affected by the crisis in 2008. The presence of Balassa Samuelson effect was confirmed. Despite the complications during intensity measurement, caused by problematic dividing into tradable and non tradable sectors, corresponding values are realistic.

This master thesis deals with the greenhouse effect, various gases and methods of measurement. On the greenhouse effect is viewed from its historical dating, despite changes in atmospheric composition. It contains a theoretical analysis of the individual gases. It focuses on the most harmful greenhouse gases such as water vapor, carbon dioxide, nitrous oxide, methane, ozone, chlorofluorocarbons and halons. Analysis methods for detection of gaseous substances. Part of this work is focus on the detection of nitrogen dioxide, chloro-fluorocarbon and methane. The data is processed using a ATmega’s microcontroller and then sent to an Internet server thingspeak.com. If the device proves successful, will be used as a laboratory exercise in the course Ecology in electronics.

Dilapidated immovable cultural monuments, care for them, their salvation and any other use or conservation for future generations is the last time hot topic. Despite the xpensive maintenance and often significantly (whether awaited or already paid) investments in these objects we are more and more aware that these monuments are an integral part of the cultural heritage which uniquely demonstrates creative work, effort, attempt, way of thinking and craftsmanship of previous generations, making it an indispensable and irreplaceable source of knowledge of national history and it is our moral responsibility for the cultural heritage of the past to properly take care of. More and more it is true that the level of preservation of the monuments reflects the maturity of the social system, the public sentiment and democracy in the country. In this doctoral thesis the issue of cultural immovable monuments, definitions of basic concepts in terms of valid and prepared legislation and a general description of conservation including points of view on the value of historically valuable objects and the determination of this value, is introduced. Furthermore, the basic methods usable precisely for the quantification of value including examples of their use, description of the suitability for specific needs or drawbacks of each method, are processed. The proposed methodology for quantifying the value by using multipliers is carefully documented and then presented on a specific investment objective of reconstruction and further use of the dilapidated cultural immovable monument. The aim of the doctoral thesis is to prove or disprove that the use of the multiplier of production of the national economy can build the appropriate method for quantifying the value of investments in immovable cultural monument.

This term paper is focused on theory and calculation of an induction motor with solid rotor. It is divided into six chapters, the first one being an introduction and the last being a conclusion. Second chapter is dedicated to magnetism. There is briefly description of a skin depth of a conductor and calculation method for impedance of a conductive solid. Third chapter is focused on theory of an induction machines, their construction, equivalent circuit and some of their properties. Fourth chapter is dedicated to calculation of an induction motor with solid rotor and its parameters. Fifth chapter is comparing results of calculation done in fourth chapter for an already existing motor with measured values.

The aim of this diploma thesis is to compare the influence of the country of origin effect on Czech products between Czech and Austrian university students. The first part includes description of existing theories in this field and also presents theoretical possibilities of brand and product origin communication. The empirical part introduces both markets, selected brands Škoda Auto and Pilsner Urquell and presents the interpretation of the data obtained from the questionnaire and its quantitative analysis. In the proposal part, the conclusions of the hypotheses constructed based on the empirical research in the first chapter are interpreted, the differences between both groups of respondents are discussed and author’s proposals are presented.

This diploma thesis is aimed at the issue of monitoring the existence of synergic effects of the selected consolidating entities in the Czech Republic. The aim of the thesis is to assess the existence of positive financial synergy effects for entities operating in agronomy. The decision about influence of these effects is based on the analysis of the values of selected economic indicators of the parent company and the consolidation unit.

This thesis studies comparison and connection of two spectrometric methods – low energy ion scattering spektrometry (LEIS) and secondary ion mass spectrometry (SIMS). SIMS method, despite its many positive qualities, suffers of so called matrix effect, which makes quantifiaction of data very difficult. LEIS method on the other hand is immune to this effect and so it’s suitable completion of SIMS method. As a convenient sample have been chosen AlGaN samples with various concentration of gallium and aluminium. In the first part of thesis is introduced physical essence of SIMS and LEIS method, experimental details and studied samples. In second part of the thesis there’s a description of measurements and comparison of data gained by each method.

This diploma thesis deals with the issue of merger, the individual possibilities, which can be realized. Furthermore, the interest is directed towards the motives leading to this intention and the impact of these activities. One of the strongest motives of mergers is the synergistic effect, whose existence in the selected economic sector is the primary aim of this work or the assessment of its existence in the selected economic sector in specific business entities.

This thesis deals with multi-channel methods of speech enhancement. Multichannel methods of speech enhancement use a few microphones for recording signals. From mixtures of signals, for example, individual speakers can be separated, noise should be reduced etc. with using neural networks. The task of separating speakers is known as a cocktail-party effect. The main method of solving this problem is called independent component analysis. At first there are described its theoretical foundation and presented conditions and requirements for its application. Methods of ICA try to separate the mixtures with help of searching the minimal gaussian properties of signals. For the analysis of independent components are used different mathematical properties of signals such as kurtosis and entropy. Signals, which were mixed artificially on a computer, can be relatively well separated using, for example, FastICA algorithm or ICA gradient ascent. However, difficult is situation, if we want to separate the signals created in the real recording enviroment, because the separation of speech people speaking at the same time in the real environment affects other various factors such as acoustic properties of the room, noise, delays, reflections from the walls, the position or the type of microphones, etc. Work presents aproach of independent component analysis in the frequency domain, which can successfully separate also recordings made in the real environment.

This master’s thesis deals with the calculation of electrodynamic forces breaker BD250NE305. Main tasks in this semester project is to study the theoretical analysis of individual parts specified breakers. Processing theoretical analysis of these forces. Creating a 3D model current path and sheets quenching chamber single phase circuit breaker in Autodesk Inventor Professional 2012. Another challenge is the subsequent export the model into the simulation program ANSYS Maxwell. After simulation, the specified conditions must be processed and the results of the present work is to evaluate.
