Tunnelling in České Středohoří
Rychnovský, Vojtěch ; Mašín, David (advisor) ; Ježek, Jan (referee)
This work contains the information about the Prackovice tunnel, tunnel across the České středohoří highland on highway D8, geological structure of the area, advanced works and the process of construction. The work also includes a 2D numerical analysis of the Prackovice tunnel using the finite element method. Parametric study and back analysis were carried out, therefore an original model could be modified to comply with the results of geotechnical monitoring. This led to better compliance between the model and reality.

Revision of Lepidodendron lycopodioides and L. selaginoides from Czech Carbon...
Rychnovský, Vojtěch ; Opluštil, Stanislav (advisor) ; Kvaček, Zlatko (referee)
The diploma thesis is focused on revision of the type collection of two similar arborescent Carboniferous lycopsids Lepidodendron lycopodioides and Lepidodendron selaginoides. Both species are often misinterpreted in the literature due to their obscure definition by Sternberg. Both species were revised morphometrically, allowing for their redefinition based on morphological characters. The emended diagnosis of both species is provided. Using of existing names of the species was solved in accordance with the International botanical code. Changes in various parametres during ontogenetic development of L. lycopodioides and L. selaginoides were described in detail by using morphometric analysis and both species were redefined. Klíčová slova: Lepidodendron lycopodioides, Lepidodendron selaginoides, pennsylvan, Intra-Sudetic Basin, Radnice Basin, morphometric analysis.
