Application Analysis Of A Cellular Geographic Information System, Michael Edward Wehde
Application Analysis Of A Cellular Geographic Information System, Michael Edward Wehde
Electronic Theses and Dissertations
AREAS, the Area REsource Analysis System, was developed by the author as an analytical tool for resource data manipulation in a spatial context. The data base and processing software design factors relevant to economical application are reviewed. The investigation seeks to define a procedure for selection and justification of the grid cell size used to quantify the spatial domain. The performance of a cellular information system is measured in terms of mapping and inventory accuracy. These measures of performance are evaluated for various cellularizations of a single map. The interboundary distance distribution is justified as the only unique characterization of …

Audio Triamplification System., John James Mccure
Electronic Theses and Dissertations
This thesis is for the purpose of determining if active filters are useful as audio crossover networks and in particular if they are better than passive crossover networks. An entire audio reproduction system was constructed with the express design intent of linear operation in two separate modes. These two modes being, first, a conventional single power amplifier passive crossover system, and second, an active filter triamplification system. Both systems were subjected to three different objective tests and one subjective test. The subjective testing included a wide spectrum of listeners ranging from rank amateurs to highly trained recording and mixing engineers. …
