Polarization mode dispersion
Turský, Aleš ; Dostál, Otto (referee) ; Filka, Miloslav (advisor)
The work deals with dispersive effects of single mode fibers. We learn about the chromatic dispersion, the main attention is paid to the Polarization Mode Dispersion. We clarify the root cause origin of the Polarization Mode Dispersion describing parameters and its effect on transmitted data. Further on, the works dedicates to measure methods of the Polarization Mode Dispersion which is the interferometric method or the POTDR method. We explain the ways of the PMD removal at contemporary optic routes and options of PMD compensation by using compensators of various types. There is also mentioned the possibility of profiting from the soliton transmission. The last chapter deals with measuring of a real optic route. It includes measured data and its evaluation due to the ITU-T demands.

Designing circularly polarized antenna for frequency band 2,4 GHz
Jiříček, Zbyněk ; Oliva, Lukáš (referee) ; Lukeš, Zbyněk (advisor)
Diploma thesis is focused to design of a system with circularly polarized wave for frequency band 2.4 GHz. The thesis introduces question of the microwave antennas, matching circuits and circular polarization circuit. It also includes a design of a circuit for available chip antenna (2450AT45A100) measurement and its measuring with connected chip antenna. Design and measurement of a circular polarization circuit using available chip antennas are also included in this thesis.

The social-economic polarization in Czech Republic
Kozáková, Lucie ; Macháček, Jaroslav (advisor) ; Říhová, Gabriela (referee)
This thesis main topic is the social-economic polarization in Czech Republic and its development process within past two decades. The main aim is to define growth poles with positive social-economic development and peripheric areas with stagnating or negative development. Consequently the secondary aim of this thesis is to confirm or disprove hypothesis resulting from Myrdal's theory of cumulative causation: "Growth poles grow faster over time and conversly peripheric areas decline further over years." In next step growing and peripheric regions are described and the possible causes of develepment within this areas are interpreted. Leading theories of regional development focusing on social-economic growth polarization are described in the theoretical part. The emphasis is on core -- periphery theories with main focus on theory of cummulative causation by Gunnar Myrdal.

Polarization of Economic Growth in the European Union
Martincová, Eva ; Damborský, Milan (advisor) ; Říhová, Gabriela (referee)
The theme of diploma thesis "Polarization of Economic Growth in the European Union" belongs to fundamental issues of recent regionalistics. The main aim is to demark poles of economic growth and periphery areas within the EU territory. This aim is followed by hypothesis that "at recent economic circumstances, economic activities are concentrated in the central part of the EU". First part of the thesis focuses on theoretic approaches, including economic growth poles definition, finding general factors of economic attractiveness of the region, their evolution and yet known findings about concentration of economic growth in the EU in economic, social and environmental dimension. In the following practical part, the main economic, social and environmental indicators are established. Using these indicators, areas that feature strong polarization of economic growth and in opposite, areas that can be marked as periphery, are defined within the EU.
