Susceptibility Modeling And Mission Flight Route Optimization In A Low Threat, Combat Environment, Brett J. Machovina

Electronic Theses and Dissertations

Movement and transportation systems are a primary topic in the study of humans and their relationship with the environment. Only a few modes of transportation allow for nearly full freedom of movement that is unconstrained by rigid nodes and networks. Individual human travel (walking, climbing, swimming, etc.) is one example while rotorcraft travel is another. Although other criteria constrain movement, independence from a network allows for a unique examination of human spatial decision-making and choice behavior. This research analyzes helicopter flight route planning in a low threat combat environment with respect to geography. The particular problem addressed, which ultimately concerns …

Tracking Sources Of Enrollment At Etsu Through The Use Of Gis., Charles Thomas Phillips

Electronic Theses and Dissertations

The objective of this research is to look at fall freshmen enrollment data for East Tennessee State University and see if patterns in the enrollment exist. This paper focuses on fall freshmen enrollment during the years 1997, 2002, and 2007 at ETSU. Once the data were gathered, they were mapped and statistically analyzed using geographic information systems (GIS) and statistical analysis software.

Many things were learned from the GIS maps created and statistical analysis. First, the maps showed that from 1997 to 2007, ETSU's enrollment became more consolidated in the East Tennessee region and moved westward into Middle and Western …

United States Land Cover Land Use Change, Albedo And Radiative Forcing: Past And Potential Climate Implications, Christopher A. Barnes

Electronic Theses and Dissertations

Land Cover Land Use (LCLU) change affects Earth surface properties including albedo that impose a radiative forcing on the climate. Recent spatially explicit satellite derived contemporary LCLU, albedo, and projected LCLU data are used to study the impact of LCLU change from 1973 to 2000, and from 2000 to 2050, on albedo and surface radiative forcing for the conterminous United States. Four research hypotheses concerned with past and potential future climate implications of LCLU change are addressed. The research described in this dissertation makes an important contribution to advancing understanding of the role of LCLU change on the climate system, …
