New mapping of post-industrial landscape in Czech Republic
Kolejka, Jaromír ; Klimánek, M.
Using additional databases on industrial architectural heritage, 128 examples of post-industrial landscapes (PILs) were identified on the Czech territory. These PILs were subdued to the genetic classification. One-to four-word-names were applied to describe individual PIL types. Their geographic distribution was analyzed in the Czech Republic.

Differentiation of dwarf pine covers in the Hrubý Jeseník Mts. with regard to their effects on mountain landscape and hazards related to its clearance
Buček, A. ; Culek, M. ; Friedl, M. ; Kirchner, Karel ; Maděra, P. ; Pecháček, J. ; Roštínský, Pavel ; Sedláček, A. ; Šenfeldr, M. ; Špinlerová, Z. ; Štykar, J. ; Tippner, A. ; Vavříček, D.
The report includes a collection of research studies dealing with selected effects of dwarf pine vegetation on abiotic and biotic natural components and potential hazards related to their clearance, proposed with regard to unoriginality of this species in mountain landscape of the Hrubý Jeseník Mts. Various subjects are solved, involving dwarf pine covers spatial extension, relations of dwarf pine vegetation to geomorphological processes, dominantly slope deformations, its effects on climate, hydrological and nival processes, soil conditions and spruce populations in upper timberline ecoton, geobiocenological typology of the Hrubý Jeseník Mts. summit positions, mapping dwarf pine covers, biotope evolution after their clearance and their biomass quantity.

Preparation procedure methodology of dwarf pine covers clearance in summit positions of the Hrubý Jeseník Mts
Buček, A. ; Culek, M. ; Friedl, M. ; Maděra, P. ; Matějíček, J. ; Pecháček, J. ; Roštínský, Pavel ; Šenfeldr, M. ; Špinlerová, Z. ; Tippner, A. ; Vavříček, D.
The study summarizes principal natural and social hazards related to planned clearance of dwarf pine covers in the Hrubý Jeseník Mts. and proposes preparation procedure of its future projects leading to their minimalization. The main hazardous factors include change of hydrological condidions, rill and sheet erosion, introskeletal erosion, snow movements, changes of soil rentention ability, increased motion of visitors, changes of timberline and spruce growth and biomass quantity of dwarf pine covers. The report is completed with calculation of damage amounts caused to forest owners due to dwarf pine clearance from forest grounds and some additional economic aspects of this activity.

Mass and energy inputs/outputs in the energy complex Dukovany-Dalešice and their impacts on the landscape
Hrádek, Mojmír
The Dukovany-Dalešice energy complex, situated west of Brno consist of the Dukovany nuclear power station (NPS) and of the Dalešice pumping power plant (PPP) with equalization reservoir. Geomorphic investigations were targeted the landforms and processes related with mass and energy inputs/outpust and their potential negative impacts. Individual landforms affected by negative impacts were analyzed in detail with using of a systém aproach. Inputs into NPS are limited to the water supply outputs are conncted with some negative response with direkt and indirect human impacts (erosion caused by waste water, equalization reservoir´s bank erosion, hillslopes stability exceeding and lanslide origin etc.).

Shading of Bézier Patches
Kolcun, Alexej ; Bocek, J.
There are well known shading algorithms (Gouraud, Phong) for the surfaces shading. The problem is that such algorithms just approximate the real shading. Precise shading algorithms require the values of normal vectors at all points of rendered surface. Computation of normal vector for Cartesian and triangular parametric surfaces is presented in the paper.
