Master´s thesis deals with possibility of choice different legal forms of business in the economic environment of Czech republic and choice of the enterprise which is the most suitable from the sight of income tax. I deal with choice of an appropriate type of partnership and comparison of different legal forms, which are based on the analysis of individual types of partnership by important criteria. Especially I focused on the criterion of the tax burden. Besides of the criterion of the tax burden it´s necessary also mention and judge the proper place - seat of an individual/a legal entity which is connected with taxation to the individual country. And take possibility of international tax planning into consideration. The aim of the thesis is to find and choose the most appropriate legal form of the enterprise to the potential entrepreneur.

This work follows the studies focused on obesity, its global extent and its serious health and economic impact. At the same time, the work examines the unsuccessful fight of public policies which try to reverse growing prevalence of obesity. Nevertheless, the main goal of the thesis is a discussion about priorities of new orientation in the research on the causes of the obesity epidemic and effectiveness of precautions that were taken in many countries and international organizations with the main aim to stop the obesity and its consequences. The discussion leads to the more detailed description of the problems connected with obesity, for instance, environmental aspects, housing culture in relation to physical activities, lifestyle in relation to advertisement/marketing, psychological and socio- psychological aspects, combating stress, etc. My intention was to find out utility of contemporary research on obesity for setting of policy fighting against obesity. At the same time, I wanted to find out other possible directions in the research into this field and discover how the discussion about priorities of the research in the experimental community proceeds. Two international dimensions of paradigmatic approaches separated to the certain degree can be considered as relevant with regard to the global...

The dissertation thesis deals with the investigation of the coexistence of GSM–EDGE and UMTS systems with focus on the physical layer of the systems. The aim is to provide a set of recommendations for practical cooperation while the systems operate in both the separated and the common radio bands. A detailed description of signal processing of both the systems on the physical layer is presented. On the basis of this description, models of both systems were created and implemented in the MATLAB environment. The simulations are focused on the physical layer quality parameters, especially the bit error ratio evaluation for various ratios of useful signal power to noise power during the transmission over the radio channel. Simulation is also used to examine the quality of received useful signal while it is interfered by signals from the same and adjacent channels. The purpose is to determine the isolation between these adjacent channels, when the bit error ratio of the useful signal does not exceed a certain reference value. The simulation results are subsequently subjected to comparison with the results of the experimental measurements in laboratory conditions. Before the measurements are carried out, a study of possible interference types is performed. Consequently, the crucial parameters of the measuring equipment used are verified. From the results of simulations and measurements, the proposal of a minimum and recommended carrier separation between both the systems is presented in order to efficiently utilize the assigned frequency spectrum. Furthermore, for the cooperation in both the separated and the common radio bands, the necessary precautions are given for reaching the required isolation and thereby inter-system interference minimization.

The purpose of this master’s thesis is foremost to provide a simple guide how to build elements of optical metropolitan area network. The basic model consists to sequence of construction, network topology, passive and active parts. The collection contains examples of alternative technology such as Wireless LAN with different frequency. The optical network construction based on optical cable, fibres, splices, trays, adapters, connectors and active parts for example a lot of media convertor models. After that there are demonstrating type of wavelength division multiplexer used in metropolitan area network – passive planar PCL splitter. One of the passive planar splitter are used to increase optical fibre channel. At the end of the collection a simplified examples of used measurements – optical time domain reflectometry and optical fibre transmission. Contains standard protocols or reflectogram. The conclusion of this thesis summarizes costs of FTTb (Fibre To The Building) model of optical metropolitan area network in Czech republic and future contribution for society.
