Geodynamical Map of Moravian and surrounding.
Rajnoha, Milan ; prof. Švábenský (referee) ; Pospíšil, Lubomil (advisor)
Result of this graduation theses is Geodynamic map of Moravia in scale 1:500 000. There were used available data from GPS measurements, seismic, geomorphologic and other data to construct map. Map is worked in GIS software. On the backround of researched data, there are determinated some locations, which are characterized by recent tectonic activity. These are analyzed for more detail.

Map of geodynamic phenomena in Lower Tatra area
Jackulíková, Denisa ; Bartoněk, Dalibor (referee) ; Pospíšil, Lubomil (advisor)
This investigative thesis provides an overview of the structural and kinematic formation of the Low Tatras in Slovakia. Numerous geological and geomorphological data from previous studies of the researched area were available. These were processed in a graphical user interface ArcMap to produce the Geodynamic map of Low Tatras at a scale of 1:200 000. By illustrating geodetic, geomorphologic, geophysical and other similar data on this map, it was possible to undertake a detailed analysis of the area and allow an assessment of the overall tectonic activity. This revealed two regions with higher than normal stress levels and therefore an associated increase in the risk of future seismic activity.

Use of starch and glycerin in polymer films with controlled life span
Almásyová, Zuzana ; Pospíšil, Ladislav (referee) ; Jančář, Josef (advisor)
This diploma thesis deals with preparation and testing of biodegradable materials for use in the packaging indrustry. The task of this work is to prepare set of laboratory made films based on wheat starch, glycerol, polyvinyl alcohol with the addition of a suitable additive, which has been selected as citric acid. A suitable composition meeting the requirements of the packaging foils has been found. Quaternary blends from all components achieve the best results. It has been found that citric acid can influence the chemical structure and thus affect the mechanical and thermal properities and also the degree of solubility. The films were characterized in terms of mechanical properities by tensile testing and thermal stability by means of thermogravimetric analysis with respect to the phase structure. The structure was characterized by Fourier transform infrared spectroscopy and confocal laser scanning microscopy. The biodegradability of the film was tested by its solubility in aqueous medium.

GPS measurements at the Tetčice polygon
Darmopilová, Jana ; Švábenský, Otakar (referee) ; Pospíšil, Lubomil (advisor)
This thesis deals with periodical measurements at the Tetčice polygon to confirm geological activity caused by geological shift that pass through the center of the village. This work was focused on the third phase of measurement by long static GNSS observation in summer 2013 to monitor horizontal shifts on both edges of Boskovice furrow. Points are stabilized on pillars with forced centring. Part of the thesis is summary of present results, the differences between the various stages and graphical representations of shifts. The theoretical part deals with the geological conditions in the area and description of GNSS technology.

Map of geodynamic phenomena in the Slanské vrchy Mts., and surrounding.
Lazoríková, Monika ; Weigel, Josef (referee) ; Pospíšil, Lubomil (advisor)
The aim of the diploma thesis has been evaluation of available geodetic, geomorphological, geological and geophysical data and other possible map data, which are related to the motion and geodynamic properties in this part of Western Carpathians. The purpose has been also to evaluate possible kinematic relations and design appropriate areas for further GNSS monitoring. Especially Slanské vrchy area is located in the zone where there are no supporting GNSS points, despite the area is situated on the main tectonic breaks of eastern Slovakia. The results and all supporting materials have been processed in the GIS program and summarized in the basic geodynamic map of Slanské vrchy and the surroundings.

GIS ANALYSIS IN BUILDING INFORMATION MODELS
Černý, Martin ; Kubíček,, Petr (referee) ; Vyhnálek,, Rudolf (referee) ; Bartoněk, Dalibor (referee) ; Pospíšil, Lubomil (advisor)
This dissertation thesis are concerned about the Geographic Information Systems (GIS) and spatial analyses inside of the Building Information Models (BIM). BIM and GIS are compared from different points of view like data organization, geometry types and modelling paradigms. Results of this comparisons are applied in the first case study where BIM data in IFC format are converted to the SHP format usable for spatial analyses in GIS. The results of the case study are evaluated and new approach for spatial analyses in BIM models is proposed based on the results. The new proposed approach is based on the semantic relations existing in the BIM models. Thesis are concluded with the future development which is in line with authors actual focus.

Single Stage Steam Turbine
Koutný, Filip ; Pospíšil, Lukáš (referee) ; Fiedler, Jan (advisor)
This diploma thesis aims to thermodynamic calculation, carbon ring seal calculation and integrated gearbox calculation of single stage mechanicl drive steam turbine. The theoretical part of this work presents general classification of steam turbines, mechanicl drive steam turbine, types of blading and design of turbine seals. In the second part, we further discuss difference between carbon and labyrinth packing.
