Porosity of different rocks in relation to capturing/moving of gases and liquids
Řimnáčová, Daniela ; Vöröš, Dominik ; Natherová, Vendula ; Přikryl, R. ; Lokajíček, Tomáš
Variability in the porosity of natural rocks and waste have been investigated in relation to the influence on the\npermeability of gases and water. The samples were of sedimentary or igneous rocks, carbon-rich rocks, and solid\nporous waste material after thermal conversion. Using mercury intrusion porosimetry, porosity values and pore\nsize distribution varied with the origin of materials. These results have been compared and a connection between\nthe origin and porosity of material was observed. Total porosity values of selected samples ranged from ca. 0.2%\nfor granite to 55% for waste porous material. Lower porosity values demonstrate the connectivity between\nmesopores or micropores and are related to the capturing of greenhouse gases, while higher porosity is caused\npredominantly by the presence of macropores and coarse pores, which serve as pathways for permeability of\ngases and liquids.

Evaluation of rock masses on planetary surfaces
Boldbaatar, Dayansetsen ; Kletetschka, Günther (advisor) ; Mikuláš, Radek (referee)
The understanding of rock mass has great benefits in engineering and geology. This understanding can benefit in the field of colonizing and terraforming other planetary bodies. To achieve this task, we can begin by using current methods to see if we can evaluate rock mass and if these can be inferred to understanding rock mass on other planetary bodies. Therefore, this bachelor's thesis is sought to examine if the use of compositional and volume information in order to figure out the mass of a rock pebbles on planetary bodies. For this purpose, 3D computing Photogrammetry method and X-ray Fluorescence methods were used to derive the necessity physical quantities for the mass computing. Five rocks where used in this study. Data was collected and analyzed using the two methods, software program and instruments. The results showed use of the two methods were accurate and efficient. Compare to the classic methods, these two methods proved as efficient and accurate.

Evaluation of rock masses (pebbles) on planets
Boldbaatar, Dayansetsen ; Kletetschka, Günther (advisor) ; Mikuláš, Radek (referee)
This research is science engineering topic based on compositional and volume information to figure out the mass of a rock pebbles on a planetary surface. For this purpose, 3D computing Photogrammetry method and X-ray Fluorescence methods were used to derive the necessity physical quantities for the mass computing First section discusses the moon, its characteristics and possibility of terraforming. The second half of this bachelor's thesis is focused on modeling and its techniques. The final part summarizes the results derived from modeling chapter.

Integration of climbing databases with the state map series
Lněničková, Petra ; Lysák, Jakub (advisor) ; Gamrát, Jakub (referee)
INTEGRATION OF CLIMBING DATABASES WITH THE STATE MAP SERIES Abstract This thesis is about the role of inegartion of climbing databases with the state map series and vice versa. I tis based on the web claimbing databases of rocks and state topographic databases Geonames and ZABAGED®. Thesis was created with the help of software tools Oracle SQL Developer and ArcGIS for Desktop. At first, basic terms are explained and a method for integration of data into climbing databases is described and tested. Subsequently, means for completion of coordinates from publicly available sources is described. At last, the process of using climbing data in topographic databases is designed. key words rocks, climbing, topographic database, ZABAGED®, Geonames
