Precision Navigation Using Pre-Georegistered Map Data, Frederick C. Webber
Precision Navigation Using Pre-Georegistered Map Data, Frederick C. Webber
Theses and Dissertations
Navigation performance in small unmanned aerial vehicles (UAVs) is adversely affected by limitations in current sensor technology for small, lightweight sensors. Because most UAVs are equipped with cameras for mission-related purposes, it is advantageous to utilize the camera to improve the navigation solution. This research improves navigation by matching camera images to a priori georegistered image data and combining this update with existing image-aided navigation technology. The georegistration matching is done by projecting the images into the same plane, extracting features using the techniques Scale Invariant Feature Transform (SIFT) [5] and Speeded-Up Robust Features (SURF) [3]. The features are matched …
Ion Channel Modulation By Photocaged Dioctanoyl Pip2, Junghoon Ha
Ion Channel Modulation By Photocaged Dioctanoyl Pip2, Junghoon Ha
Theses and Dissertations
Phosphatidylinositol bisphosphate (PIP2) directly regulates electrophysiological activity in a diverse family of ion channels whether the effect is stimulatory or inhibitory. Much has been unveiled about the apparent affinity and modulatory function of PIP2 using a chemically modified dioctanoyl PIP2 (diC8), a membrane delimited cytosolic co-factor in inside-out macropatch experiments. Yet, the scarcity of molecular tools that permit fine external control in whole-cell systems has precluded future studies from probing the physiological role of PIP2 in cells in the presence of a fully intact cytoplasm. Here we introduce light as an external control for PIP2 through photocaging of diC8, and …

The purpose of the study was to identify factors that affect whether or not students persist in completion of the GED. Exploration of characteristics of participants that do/do not persist and obtain their GED not only assists the high school dropout, potential GED recipient, and GED program staff, but also society as a whole. More information was needed in order to effectively address issues that adversely affect students enrolled in GED programs at rural community colleges. Therefore, examination of the GED program’s student database contributed in finding factors that both help and impede student success. Factors identified were investigated in …
Use Of High Resolution Microscopy (Fesem And Tem) To Investigate Carbonate Precipitates In Association With Organic Matter From Hot Spring, Salt Pond, And Reef Environments, Margaret Elizabeth Corley
Use Of High Resolution Microscopy (Fesem And Tem) To Investigate Carbonate Precipitates In Association With Organic Matter From Hot Spring, Salt Pond, And Reef Environments, Margaret Elizabeth Corley
Theses and Dissertations
Carbonate precipitates in biofilm were investigated from hot springs near Viterbo, Italy; Salt Pond, San Salvador; and Fowl Cay Reef, Abaco, Bahamas. Features shared by hot springs and salt ponds are supersaturation with CaCO3, abundant Spirulina, and clustered acicular aragonite crystals termed “fuzzy dumbbells.” TEM and FESEM microscopy show fuzzy dumbbells contain a core of amorphous organic matter and subhedral CaCO3 microcrystals arranged in linear fabrics. Micron- to millimeter-scale microenvironments are identified by localized dissolution, the occurrence of gothic calcite inter-grown with organic filaments, and the presence of calcite in biofilm where aragonite is chemically favored. Spherical CaCO3 precipitates in …

Spatial Dispersion Of The Fungus Aspergillus Flavus In Corn Ears: A Spatial Analysis Of Ubiquitin Mrna, Leif Saxon Mylroie
Theses and Dissertations
Aflatoxin is a carcinogen produced by the fungus Aspergillus flavus that causes millions of dollars in agriculture losses in the southeastern US. This thesis examines the dispersal of A. flavus on two corn inbred lines, resistant (Mp313E) and susceptible (B73), which differ in total aflatoxin accumulation after infection with A. flavus. After inoculating corn kernels with the fungus an RNA analysis was used to determine the location (number of kernels away from inoculation site) and abundance of A. flavus at weekly intervals. A. flavus started its spread at 7 days after inoculation (DAI) on both corn lines. The B73 corn …

Intercategory And Interbasin Comparison Of Storm Surge Height, Ashley Nicole Mcdonald
Intercategory And Interbasin Comparison Of Storm Surge Height, Ashley Nicole Mcdonald
Theses and Dissertations
Hurricanes strike the coast along the Gulf of Mexico and eastern seaboard of the United States annually. With each hurricane that makes landfall there is potential for significant damage and destruction with the majority of coastal devastation occurring from storm surge. It is accepted that hurricane strength, classified byt the Saffir-Simpson scale, and storm surge height are directly proportional. However, this scale my prove to be a false representation of surge height, especially according to location of landfall. This study will discuss the correlation between category 2, and greater, hurricanes and corresponding storm surge heights between the Gulf Coast and …

Stable carbon isotope analyses of the humin fraction of the soil organic matter were conducted on more than 160 soil profiles from Tikal, Guatemala. The profiles were collected from near areas associated with the earthworks of Tikal; an ancient ditch and parapet construction hypothesized to have formed ancient boundaries of the polity. In addition to the isotope analyses, the physical and chemical characteristics of the horizons were determined. Maize, a C4 plant, formed an integral part of the ancient Maya diet and is the only known C4 plant cultivated by the Maya. Prior to and subsequent to the ancient Maya …
Map, Manuscript, And Memory: The Emergence Of An Anglo-Saxon Identity Between Origins And Apocalypse, Juliana Marie Chapman
Map, Manuscript, And Memory: The Emergence Of An Anglo-Saxon Identity Between Origins And Apocalypse, Juliana Marie Chapman
Theses and Dissertations
As the only extant detailed world map of the Anglo-Saxon period, the Anglo-Saxon map, c. 1025, presents a unique opportunity to explore a sense of Anglo-Saxon social identity as evidenced in this graphic worldview. The Anglo-Saxon map has most often been dismissed as an ill-fitting illustration when viewed solely in its manuscript context or an equally poor navigational tool when considered in the context of modern cartography. The purpose of this thesis is to present the argument that the Anglo-Saxon world map is neither simply a bad illustration nor a poorly rendered map intended for travel, but is rather a …

This recent shift in focus to more long- duration missions has moved researchers in the direction of analyzing crew performance aspects associated win, crew dynamic development on such long missions. More recently researchers have been analyzing past expeditions carried out on Earth, as these expeditions kept records of crew performance, which have been compared and analyzed to those reported on space missions. Purpose: This study …
Solar Variability And Climate Processes: The Influence Of Fluctuating Solar Spectral Irradiance On Differential Surface Heating As A Function Of Soil Geochemistry And Radiation Absorption Characteristics, Susan Wahl
Theses and Dissertations
The influence of solar variability on climate has received increasing attention. Much of the research has dealt with fluctuating ultraviolet radiation and its effects in the stratosphere; decadal signatures in cloud cover and their relationship to cosmic rays; and correlations of surface air temperature with various proxies (e.g., sunspot numbers; 10Be from ice cores and marine sediments). Much of the research has focused on changing solar radiation within the upper atmosphere and the propagating effects into the troposphere. However, there is a missing component involving differential surface heating as a function of soil composition and corresponding spectral radiation absorption properties …
North Dakota's Monuments: What They Reveal Of The State's People And Their Character, Jennifer D. Heth
North Dakota's Monuments: What They Reveal Of The State's People And Their Character, Jennifer D. Heth
Theses and Dissertations
Monuments and memorials are found in every society and civilization throughout history. These structures serve as commemorations of people, events, wars, victories, and disasters. The building of monuments allows the people of a society to express for posterity their jubilation, reverence, and grief. In turn, monuments and memorials reflect the values and beliefs of the society. As a result, historians study monuments and memorials to gain a better understanding of the people, culture, and values of a society or civilization. The study of monuments and memorials, as well as commemoration in general, is a growing field in both American and …
Genetic Differentiation Of The Parasitoid, Cotesia Congregata (Say), Based On Host-Plant Complex, Georgia Karns
Genetic Differentiation Of The Parasitoid, Cotesia Congregata (Say), Based On Host-Plant Complex, Georgia Karns
Theses and Dissertations
Endoparasitoids of herbivorous lepidopterans have intimate relationships with their host species as well as the plant on which their host develops. Characteristics of both hosts and plants can affect parasitoid success in tri-trophic systems and thus, drive diversification. Genetic differentiation was estimated for Cotesia congregata (Say) collected from two distinct host-plant complexes, Manduca sexta L. on tobacco (Nicotiana tabacum L.) and Ceratomia catalpae, (Haworth) on catalpa (Catalpa bignonioides Walker), in the mid-Atlantic region of North America using seven microsatellite loci and the mitochondrial COI locus. Microsatellite allele frequencies were differentiated based on host-plant complex, and COI haplotypes from individuals on …
Patterns Of Differential Involvement In Terrorist Activities: Evidence From Dhkp/C And Turkish Hezbollah, Ismail Yilmaz
Patterns Of Differential Involvement In Terrorist Activities: Evidence From Dhkp/C And Turkish Hezbollah, Ismail Yilmaz
Theses and Dissertations
This study examines the patterns of involvement in terrorist activities for the Revolutionary People’s Liberation Party/Front (DHKP/C) and Turkish Hezbollah members. The study is based on the assumption that terrorists differ in terms of their involvement in terrorist activities. In this sense, there are full-time and part-time terrorists. Full-time terrorists act professionally and do the assignments given by their commanders. Part-time terrorists, on the other hand, act on a non-professional basis and have their own motivations to participate in terrorist activities. For part-timers, there are various factors that may have an effect on their degree of involvement in terrorist activities. …
Visualizing And Modeling Mining-Induced Surface Subsidence, Marcor Gibbons Platt
Visualizing And Modeling Mining-Induced Surface Subsidence, Marcor Gibbons Platt
Theses and Dissertations
Ground subsidence due to underground coal mining is a complex, narrowly-understood phenomenon. Due to the complicated physical processes involved and the lack of a complete knowledge of the characteristics of overlying strata, the reliability of current prediction techniques varies widely. Furthermore, the accuracy of any given prediction technique is largely dependent upon the accuracy of field measurements and surveys which provide input data for the technique. A valuable resource available for predicting and modeling subsidence is aerial survey technology. This technology produces yearly datasets with a high density of survey points. The following study introduces a method wherein these survey …
The Culture Of Habits And Dispositions: Associationist Psychology And Unitarian Education In Gaskell's Wives And Daughters, Lori Ann Dickson
The Culture Of Habits And Dispositions: Associationist Psychology And Unitarian Education In Gaskell's Wives And Daughters, Lori Ann Dickson
Theses and Dissertations
Although Victorian psychology has been the subject of much recent scholarship, Elizabeth Gaskell's work has not been considered in relation to nineteenth-century theories of mind. In this thesis, I argue that Gaskell's final novel, Wives and Daughters, deals with associationism, an early branch of psychology that played a key role in public debates over cognition that took place throughout the century. Gaskell was exposed to associationism through her Unitarian faith, and Unitarian educators in particular articulated associationist principles in their writings about cognitive development. Gaskell was preoccupied with a similar model of learning throughout her fiction, and I read …

Images Of Corsica In France: Travel Memoirs And 19th Century Writers, James Oliver Mayo
Images Of Corsica In France: Travel Memoirs And 19th Century Writers, James Oliver Mayo
Theses and Dissertations
Considered an integral part of Metropolitan France, the island of Corsica is situated nonetheless on the very periphery of the modern state that claims it. Actually situated geographically closer to Italy than to any part of France, its culture and its people are likewise more closely related to their Italians neighbors than to the rest of what Corsicans term "Continental France." Following the acquisition of Corsica, both government officials and bourgeois travelers would seek to visit the island, often recording their findings and publishing these memoirs for others to know of their travels. This concept of travel memoirs, specifically those …
