Metro station roofing
Filip, Radim ; Štrba, Michal (referee) ; Horáček, Martin (advisor)
The subject of the bachelor's thesis is the design and assessment of the steel supporting structure of the metro station roof. The roof is designed as a cylindrical surface. The building is designed for the Brno–Veveří location. The dimensions of the roof are 50.23 x 21 m, height 3.65 m. The structure is made of rectangular hollows, which are welded. It creates the network of equilateral triangles in the plan. Cladding is designed from glass panels.

Study of optical nonlinearities in semiconductors and semiconductor nanostructures
Chlouba, Tomáš ; Trojánek, František (advisor) ; Filip, Radim (referee) ; Herynková, Kateřina (referee)
In the main part of this thesis I study the relaxation mechanisms of charge carriers in silicon nanocrystals in SiO2 matrix. One of the potential applications of these structures lies in photovoltaics, specifically in construction of all-silicon tandem solar cells. I studied the dynamics of carriers in these structures by methods of ultrafast spectroscopy which helped to unravel the microscopic behaviour of carriers, their transport, localization etc. Furthermore I investigated the doping of such structures as the technology of doping is crucial for manufacture of pn- junctions which are the core component of solar cells. At the end I delve into the dissipative Jaynes-Cummings model by mathematical modeling and theoretical calculations which describes among others microlasers and as such comes under a field of cavity quantum electrodynamics.
