Landslides, Scree and the Other Unusual Terrain Features in Topographic Databases and Digital Cartography
Šákrová, Michaela ; Lysák, Jakub (advisor) ; Kubín, Tomáš (referee)
Landslides, scree and other specific terrain objects in topographical databases and digital cartography Abstract Topographic maps capture detailed information about terrain. In traditional analogous way of creating these maps, understandable and illustrating cartographic symbology was used. However, certain spheres of symbology were modified with transition to digital topographic databases and digital cartography. Now they carry less information and are less illustrative. Main cause of this inaccuracy is imperfection of the cartographic software, which is unable to create appropriate symbology. This diploma thesis tries to solve aforesaid problem for some specific terrain objects as scree and landslides. These shapes are distinctive geomorphologic phenomenon in terrain, but they are often neglected as their occurrence in our territory is infrequent. Key words: topographic maps, digital cartography, scree, landslide, specific terrain object
Analytic represantation of AC winding properties
Kubín, Tomáš ; Skalka, Miroslav (referee) ; Ondrůšek, Čestmír (advisor)
My bachelor thesis deals with the issue of overview diagram of magnetic fields of basic free-phase winding. It is divided into four parts.The first part focuses on basic winding types and types of their connection. The second part describes the issue of analytic calculation of the magnetic field intensity in the air gap of rotating machines. This description is easier and faster than modern method of final elements in some cases because it displays course of particular harmonics and their partial sums for selected magnetic fields. The third part presents Görges diagrams of basic winding types and finally there is a calculation of the winding factor shown on two examples in the fourth part.
Reluctance machine with permanent magnet on rotor
Kubín, Tomáš ; Mach, Martin (referee) ; Ondrůšek, Čestmír (advisor)
This master’s thesis is focuses on the reluctance motor, especially on the design of the rotor. It shows the development of the construction of rotors of reluctance motors. Furthermore, it shows the principle of reluctance machine and its basic mathematical description and the principle of improving the machine parameters by inserting permanent magnets into the rotor. It offers an overview of patents available from 2000 to present. Also it deals with the design of the rotor with permanent magnets for stator of induction motor.
Jet Grouting
Kubín, Tomáš ; Boštík, Jiří (referee) ; Glisníková, Věra (advisor)
The aim of this thesis is to describe jet grouting. There are specified base methods of ground improvement and described possibilities of jet grouting. Furthermore thesis is focused on certain constructions and reconstructions in Brno, where this method was used. In detail it is concerned on reconstruction of the palace of Chlumecky, where jet grouting was used as shoring of foundation pit. Next part of this thesis is a numerical model of this foundation pit and comparison of the results from different constitutive models of soil.
