Binary Programming Models Of Spatial Pattern Recognition: Applications In Remote Sensing Image Analysis, Thomas G. Reed Dec 1991

Binary Programming Models Of Spatial Pattern Recognition: Applications In Remote Sensing Image Analysis, Thomas G. Reed

Theses and Dissertations

The major purpose of this investigation was to implement subregion allocation objectives using a network model base on an existing subregion allocation binary programming model (Benabdallah and Wright (B&W), 1990), the ultimate goal being the application of subregion allocation concepts towards the spatial analysis of satellite imagery. The multi-objective aspects of subregion allocation can be accomplished via a network formulation, a formulation vastly simpler in complexity than the binary programming models previously used. Without a network programming package that could maintain integral flows, however, deriving the solution was a tiresome task for the user. Nonetheless, several new concepts and advantages …

Application Of Mixed H2/H∞ Optimization, John J. Kusnierek

Theses and Dissertations

A non-conservative optimization technique is utilized to examine the problem of minimizing the 2 norm of one transfer function subject to an ∞-norm bound on another transfer function. For single exogenous input/ single exogenous output systems this non conservative mixed solution is shown to be up to 5% better in a specific example. For single exogenous input/two exogenous output systems the mixed solution is shown to be up to 27% better than a previous technique for a specific example. Finally, a two exogenous input/two exogenous output practical system is examined to demonstrate the utility of this mixed optimization technique.

Comparative Analysis Of Guidance Algorithms For The Hyper Velocity Missile And Afti/F-16, Edward G. Rice Nov 1991

Comparative Analysis Of Guidance Algorithms For The Hyper Velocity Missile And Afti/F-16, Edward G. Rice

Theses and Dissertations

This project has provided me with endless intrigue. In considering the problem of guiding a hyper-velocity missile from a moving platform to a moving target, a common perception said it was just another Kalman Filtration design challenge. I began with lofty intentions of running a full up extended Kalman filter simulation but I became enthralled with the limited work available on the physical limitations of basic guidance algorithms. This became the emphasis of this project. The best filter scheme cannot overcome a guidance algorithms physical limitation. Only with an understanding of these limitations can one effectively integrate a guidance scheme …

Patterns Of Undermining: American And British Novels Set In Coal-Mining Locales., Julie Ann Maristuen-Rodakowski Oct 1991

Patterns Of Undermining: American And British Novels Set In Coal-Mining Locales., Julie Ann Maristuen-Rodakowski

Theses and Dissertations

This dissertation focuses on twenty novels--ten by men and ten by women--set in coal-mining locales circa 1840 to 1940. It analyzes power relationships and structures of oppression that emerge through the fictional techniques of setting, character, and theme, positing that a paradigm shift is visible in some texts. Hegemonic power relationships and the accompanying oppression of the "less important" entity in male/female, management/labor configurations are evident in many of the novels, but some texts treat the power relationships differently. In these texts, the role of the women and the role of the laborers shift from that of a marginalized Other …

Reality Monitoring And Schizophrenia., Richard Gammon Whitten Oct 1991

Reality Monitoring And Schizophrenia., Richard Gammon Whitten

Theses and Dissertations

Reality monitoring is a postulated cognitive process by which memories for sensation-based or "real" events are differentiated from memories for thoughts or imagination-based events. Past research indicates that when there is uncertainty about the source of memories (whether sensation or imagination), normal male adults are biased and tend to report an imaginal origin ("I must have thought it."). In contrast, male subjects diagnosed with schizophrenia who also exhibit psychotic speech or thought disorder, reportedly are biased toward reporting a sensation-based origin for uncertain memories ("I must have said it."). In order to further explore the relationship between different kinds of …
