This diploma thesis was focused on study of barrier and transport properties of selected polyelectrolytes in hydrogel matrices by using diffusion techniques. The study of these properties was performed in horizontal diffusion cells where is observed the change in diffusion probe concentration over time. Diffusion experiments were performed on an agarose hydrogel with the addition of alginate, hyaluronic acid, polystyrene sulfonate, humic acids and as a model probe rhodamine 6G was used. Important parts of this thesis are also the methods which characterize the substances and hydrogel matrices such as rheology and potentiometric titration. The main aim of this diploma thesis was to investigate the effect of interactions between passing model dye (rhodamine 6G) and the appropriate gel (agarose + polyelectrolyte) on the fundamental diffusion parameters (effective diffusion coefficient, lag time, etc.).

Transport phenomenon of gas and vapors through polymer barrier materials as well as the factors affecting permeability of gaseous and liquid toxic compounds were investigated and results are presented in this thesis. Permeation characteristics investigation methods were elaborated and verified with focusing on utilization of gas chromatographic method and its instrumental modifications.

The main aim of this thesis is in analyzing and empirically testing the various valuation models and hedging schemes of foreign exchange barrier options and their robustness with respect to changing of market conditions. The purpose of the main empirical section is to get a detailed understanding of the static and dynamic performance of the analyzed models for the barrier options payoff mainly in the extreme market conditions, where we performed a benchmarking of the various hedging schemes. As a by-product, we analyzed the accomplishment of some of the model assumptions in real world setting, and the model dependency of the barrier options.

Diplomová práce primárně řeší zda jsou exotické opce vhodné pro zajištění kurzových rizik a přináší návrh vhodné aplikace exotických opcí. Práce je zaměřena na úzkou skupinu exotických opcí, tzv. Path-Dependent opce. Tři často používané typy těchto opcí jsou analyzovány a testovány jak mezi sebou tak pro lepší porovnání i s klasickou vanilla opcí. Hlavním výstupem diplomové práce je návrh vhodného využití testovaných exotických opcí.

The area is located in the north part of Brno (Řečkovice a Mokrá Hora) and is surrounded by a housing estate. To the south of this area is a complex of former barracks. In our project we propose to use the area as a residential district with public amenities. Sports ground and the park are included. Currently there are terraced houses and separated family houses. We especially use low-floor blocks of houses with no more than four floors. Orientation of the blocks corresponds with the fact that this area is on the north slope. Family houses with gardens are situated on the east side of the area. The area is accessible from the Žilkova street (on the east) and from the Terezy Novákové street (on the west) – buildings on this street make a noise barrier. The square of our area is next to this street and represents a public place with public amenities (for example a retirement house and a school of art), underground car park and a pedestrian precint leading to the park. A tram stop is nearby. Sports ground and the park are situated in the north part of the area. In the central part we find the kindergarten. Underground car parks for the residents are under the blocks and its courtyards.
