Log-optimal investment
Král, Stanislav ; Dostál, Petr (advisor) ; Večeř, Jan (referee)
Suppose we have capital, which we will redistribute into investment oppor- tunities. The financial valuation of these investments will form a sequence of independent, identically distributed random vectors taking values in some clo- sed, positive interval. We will have full knowledge of the entire history of these valuations before each investment. It turns out that if our strategy is to always maximize the mean value of the logarithm return on these investments, then this strategy is in a sense asymptotically optimal. 1

Matějka, Milan ; Horáček, Miroslav ; Meluzín, Petr ; Chlumská, Jana ; Král, Stanislav ; Kolařík, Vladimír ; Krátký, Stanislav ; Knápek, Alexandr
Development in the field realization of precise relief structures in the silicon dedicated to the testing of the scanning electron microscopes (SEM) deflection field and accuracy. Micro-lithographic techniques for the recording of patterns in the silicon were used. New tools for handling during technological operations of resist deposition and etching were developed. Optimization was reached in the process of transfer of the relief structure into silicon via anisotropic etching, due modification of etching apparatus. Standardized procedures for inspection and quality control were developed.

Krátký, Stanislav ; Matějka, Milan ; Chlumská, Jana ; Horáček, Miroslav ; Kolařík, Vladimír ; Meluzín, Petr ; Král, Stanislav
Development of phased gratings manufacturing for use in transient grating spectroscopy. Possible approaches for phased gratings design were studied during the development to achieve the maximum efficiency for two different wavelengths. Theoretic simulations showed that the grating has to be adjusted for the value of wavelength (the depth of the grating) between two desired values of wavelength to achieve the maximum efficiency in first diffractive orders. The samples were manufactured with use of e-beam lithography and reactive ion etching.

The development of sandwich nanostructures on doped silicon substrate. The dimension of nanostructures and their pitch is very close to the capability of used e-beam system Raith EBPG5000+. Thin silicon nitride layer was prepared on doped silicon substrate. This layer is needed for wet etching of silicon. The golden markers needed for direct writing of multiple patterns were prepared by the way of e-beam lithography and vacuum evaporation. Mask in the resist layer was exposed for etching of the silicon nitride mask by reactive ion etching in the next step. Wet etching of silicon was carried out after the mask was prepared. Small pyramids were created by the etching process. The last lithography step was preparation of the mask over the pyramids. Thin aluminum layer in the areas where the pyramids are presented was prepared by the way of vacuum evaporation and lift-off technique.
