Modeling Geographic Population Dispersion Utilizing Geospatial Information System Environment Agents In An Agent Based Model, Karl D. Liebert
Modeling Geographic Population Dispersion Utilizing Geospatial Information System Environment Agents In An Agent Based Model, Karl D. Liebert
Computational Modeling & Simulation Engineering Theses & Dissertations
New capabilities in agent based model (ABM) environments are opening the door to the creation of ABM that may incorporate high-quality, real world environment data in the form of Geospatial Information System (GIS) files . In the past, GJS environments were only possible through extensive software development efforts focused on specific model applications.
This thesis explores the value and issues of using GIS data to provide an ABM environment. It examines the ability of ABM development environments (DE) to support GIS environment data. The selected ABM DE is then used to model population behavior in an environment defined by authoritative …

Statistical Methods For Polarimetric Imagery, Daniel A. Lemaster
Statistical Methods For Polarimetric Imagery, Daniel A. Lemaster
Theses and Dissertations
Estimation theory is applied to a physical model of incoherent polarized light to address problems in polarimetric image registration, restoration, and analysis for electro-optical imaging systems. In the image registration case, the Cramer-Rao lower bound on unbiased joint estimates of the registration parameters and the underlying scene is derived, simplified using matrix methods, and used to explain the behavior of multi-channel linear polarimetric imagers. In the image restoration case, a polarimetric maximum likelihood blind deconvolution algorithm is derived and tested using laboratory and simulated imagery. Finally, a principal components analysis is derived for polarization imaging systems. This analysis expands upon …
Predicting The Longevity Of Dvdr Media By Periodic Analysis Of Parity, Jitter, And Ecc Performance Parameters, Daniel Patrick Wells
Predicting The Longevity Of Dvdr Media By Periodic Analysis Of Parity, Jitter, And Ecc Performance Parameters, Daniel Patrick Wells
Theses and Dissertations
For the last ten years, DVD-R media have played an important role in the storage of large amounts of digital data throughout the world. During this time it was assumed that the DVD-R was as long-lasting and stable as its predecessor, the CD-R. Several reports have surfaced over the last few years questioning the DVD-R's ability to maintain many of its claims regarding archival quality life spans. These reports have shown a wide range of longevity between the different brands. While some DVD-Rs may last a while, others may result in an early and unexpected failure. Compounding this problem is …
Developing A Repeatable And Reliable Methodology To Determine Return-On-Investment, Mark Cullen Nesselrode
Developing A Repeatable And Reliable Methodology To Determine Return-On-Investment, Mark Cullen Nesselrode
Computational Modeling & Simulation Engineering Theses & Dissertations
The high costs of modern weapons systems, fuel, personnel, and increasing environmental awareness is forcing U.S. forces to rely on simulation for training. Further, the need to train in a robust and theater specific environment is critical to ensure operational readiness immediately upon reaching the combat theater. Finally, the rapidly changing nature of the conflicts, crises, or contingencies in which U.S. forces are involved requires a new approach to training.
The purpose of this research is to develop and demonstrate the feasibility of a methodology that can provide a reliable, consistent method for determining ROI in various forms, focusing on …
A System Dynamic Model Of Leader Emergence, Paul S. Wever
A System Dynamic Model Of Leader Emergence, Paul S. Wever
Theses and Dissertations
The purpose of this thesis is to develop a system dynamics model of leader emergence. Longitudinal social network and personality data were collected in a class of enlisted military professionals attending a 6-week leadership development course. Findings support known relationships in existing leadership research. The thesis demonstrates the applicability of system dynamics toward the complex social phenomena of leader emergence.
Evaluation Of An Image Processing Algorithm For Scene Change Detection, Daniel Flores
Evaluation Of An Image Processing Algorithm For Scene Change Detection, Daniel Flores
Open Access Theses & Dissertations
Despite the efforts to reduce traffic accidents by government entities and automobile manufactures, the numbers of accidents are not considerably reduced. An evaluation of an algorithm based on the fly's eye is done on this research applying its principles to detect scene change on images for printed circuit boards providing initial steps to implement this algorithm on vehicular traffic to keep track of objects moving on the field for collision avoidance purposes. The effectiveness of the algorithm is addressed through a comparison of its performance with that found in experimental data.
Allocating Emergency Response Vehicles To Cover Critical Infrastructures, Hao Lei
Allocating Emergency Response Vehicles To Cover Critical Infrastructures, Hao Lei
Open Access Theses & Dissertations
Optimal deployment of limited emergency response service units in a metropolitan area is of interests to public agencies. The limited emergency units not only have to respond to the demand for service by residents and businesses, but also cover Critical Infrastructures (CIs). This Thesis formulates an improved optimization model to allocate different types of Emergency Response Service (ERS) units among their candidate base stations. The allocation of units must ensure maximum coverage to CIs, subject to the capacities of the base stations, service standard in terms of time to reach the CIs, and the availability of the ERS units (when …
Expert System Design Guide For Lower Classification Roads Over High Pi Clays, Yaqi Wanyan
Expert System Design Guide For Lower Classification Roads Over High Pi Clays, Yaqi Wanyan
Open Access Theses & Dissertations
This research was focused on low-volume roads over expansive clayey soils in Texas. In spite of the redundant pavement designs recommended and widely used in Texas for roads in high PI clay areas, these pavements often fail prematurely. This failure occurs primarily because of the highly variable properties of the clayey subgrade throughout the year due to moisture fluctuations. The problematic nature of high PI clays, despite the fact that volumetric changes such as heaving are sometime considered in the design, is of concern since they contribute to roughness and longitudinal shrinkage cracking of the road, and as such the …
Effects Of Leader Relationship Quality (Lmx), Supervisor Support, And Upward Influence In National Science Foundation Industry /University Cooperative Research Centers, Janet L. Bryant
Psychology Theses & Dissertations
The Industry/University Cooperative Research Center (I/UCRC) is a type of partnership between industries and universities supported by the National Science Foundation. These partnerships enable the transfer of leading-edge technology developed in universities to industrial firms. Leadership plays a powerful role in the success of these research partnerships by creating an environment that is conducive to innovation. Directors of I/UCRCs must be able to successfully lead upward, that is, develop and maintain strong relationships with the university administrators to whom they report, to obtain the necessary support to sustain the center and foster innovation. This study uses leader-member exchange (LMX) theory …
