The overall goal of the thesis was to study available geographic information systems (GIS) and to explore the functionality they provide. The implementation was focused on module for vector data creation and data analysis. As examples were used existing systems like GRASS and ArcGIS. The result of this master thesis was a plug-in integrated into the GIS of DELINFO, spol. s r.o. company. The plug-in can open, modify and save vector data in shapefile format. The plug-in is also able to do some basic analysis of the vector data, such as a region intersection, a union, hit tests and a distance measurement. This thesis could be used as a pattern for vector data operations in GIS.

Indirect vector controlled induction motor drives are gaining acceptance because they allow the induction motor to be controlled like a separately excited dc motor, i.e. they achieve decoupling of torque and flux producing currents. But, the effectiveness of these drives is lost as they are highly parameter sensitive. Studies have indicated that the decoupling of the torque and the flux channels is lost when machine parameters change with temperature, saturation, etc. Many schemes have been proposed to overcome these parameter sensitivity effects. But most of these schemes themselves are parameter-dependent and hence inapplicable to high precision control applications. A new parameter compensation scheme which uses air gap power equivalence for sensing parameter changes is developed in this thesis. It is shown that this scheme is independent of key motor parameters and requires no additional transducers for implementation. / M.S.

The feasibility of using a vectorized banded direct solver for the compressible Euler and Navier-Stokes equations is examined for both single-grid and multi-grid strategies. A procedure is developed for comparing the computational effort required for the direct method with that of the vertical line Gauss-Seidel iteration scheme in order to provide a criteria for choosing between the two techniques. The direct method is shown to have a relatively wide range of application on a vector processor with large memory. Indeed, the primary limitation of the direct method at this time is machine memory. Results for both inviscid and viscous test problems over a range of Mach numbers and Reynolds numbers are examined for two dimensions. / Ph. D.
