SPATIAL ANALYSIS OF DROUGHT AND ITS IMPACTS IN THE CHICKASAW NATION
(2018-08-01)In the south central United States, drought is a prevalent natural disaster, and its impacts extend much farther than its drain on the region’s natural resources. Unfortunately, local impacts of drought may differ spatially ... -
A Spatial Analysis of Simulated Tornado Warning Decisions in the United States
(2021-12-17)The work presented in this thesis uses theories from risk perception and decision making to examine spatial variations of tornado warning decision making across the U.S. Decision-making as it relates to tornado warnings ... -
Spatial and Temporal Distribution of Obsidian in Oklahoma: Conveyance Zones on the Southern Plains
(2023-12-15)Obsidian is an exotic lithic resource rarely found in Oklahoma, yet it still occurs in the archaeological record. This project utilized Energy Dispersive X-ray Fluorescence (EDXRF) Mass Spectrometry to geochemically source ... -
Spatial comparisons among stream biota at national and regional levels
(2021-05-14)Streams are subjected to multiple anthropogenic stressors and will continue to be, far into the future. Biological monitoring is an important method for analyzing the effects of impacts on stream health and biotic communities, ... -
SPATIAL CONSEQUENCES OF PUBLIC POLICY ON THE EVOLUTION OF THE BLACK COMMUNITY; A CASE STUDY OF OKLAHOMA CITY, 1889-1974
(1977)Modern metropolitan centers and urban society in the United States are not only a cultural phenomenon of the twentieth century; they are the culmination of the past. At any point in time, the city's internal socio-spatial ... -
Spatial Ecology and Conservation of the Central American River Turtle (Dermatemys mawii)
(2021-05-14)Overexploitation of species is one of the primary causes of severe population declines. Conservation initiatives employ various strategies, such as protected land and captive breeding programs, to mitigate the effects of ... -
Spatially-Temporally Resolved Sampling System for Carbon Dioxide Concentration in The Atmospheric Boundary Layer: A Low-Cost UAS Approach
(2020-05-08)Given the consensus around the importance of atmospheric carbon dioxide (CO2) to human life on earth, its monitoring has grown significantly in the past 60 years. However, there is still a knowledge gap regarding the ... -
Spatiotemporal gap-filling of NASA Deep Blue aerosol optical depth over CONUS using the UNet 3+ architecture
(2024-05-10)Due to sensor and algorithmic constraints, satellite aerosol optical depth (AOD) retrievals are spatially incomplete over clouds, deserts, and other bright surfaces. These gaps in satellite AOD datasets represent a significant ... -
Speaking of Walls: Ontological Security Discourse and the West Bank Barrier
(2018)The official government justification for the construction of the West Bank barrier is that it was a security measure necessitated by an increase in Palestinian terrorism during the Second Intifada. There are many challenges ... -
Species Transformation and Social Reform: The Role of the Will in Jean-Baptiste Lamarck's Transformist Theory
(2021)Jean-Baptiste Lamarck is well known as a pre-Darwinian proponent of evolution; however, comparatively little has been published on his views of human physiology and development. This paper argues that the will was of ... -
Spectral Analysis of Seismic Data Using Wavelet Transform
(1999)Spectral analysis provides the frequency information of the data. Fourier tansform projects the data from time domain into frequency domain, while the time information is completely lost after the procedure. Time-frequency ... -
Spurious suppression techniques in integrated and embedded microwave components
(2021-08-05)To increase bandwidth and mitigate interference in a crowded electromagnetic spectrum, future microwave systems will move to higher operating frequencies. Because lumped elements perform poorly at high frequencies, designers ... -
The St. Johns River: An archival project investigating interior occupation of the St. Johns River Region by Native Americans during the Colonial Period
(2021-05-14)Abstract My project focuses on studying burial mounds along the St. Johns middle valley during the Colonial Period, ca. 1500-1845CE. Currently, little is actually known regarding the interior of the St. Johns or which ... -
Stability of aqueous foams at high pressure and the impact of contaminants
(2021-12-18)Foam is a mixture of gas bubbles dispersed in a continuous liquid phase that exhibits some form of structure. Foam is used in various oil and gas industry operations such as drilling, cementing, and fracking. The properties ... -
Stabilization of drilling foams using nanoparticles
(2023-05)Underbalanced drilling often uses foam because of its superior hole-cleaning capacity, low density, and reduced liquid requirements. However, it must be stable under borehole conditions to function as a drilling fluid. ... -
Stable nitrogen isotope signal in crude oils throughout geologic time
(2017-05-12)Stable nitrogen isotopic compositions of asphaltene and NSO hydrocarbon fractions from sixty-two crude oils derived from siliciclastic, carbonate/marl, hypersaline and lacustrine source rocks of known geologic age ranging ... -
STAGED THERMAL FRACTIONATION OF BIOMASS FOR SEGREGATION OF HEMICELLULOSE, CELLULOSE AND LIGNIN DERIVED PRODUCTS
(2016-05-14)The increasing industrialization and motorization of the world has led to a steep rise in the demand of petroleum-based fuels. However, negative environmental consequences of fossil fuels, natural limitation in their ... -
STAND-ALONE IMAGE RECONSTRUCTION FOR MULTI-SLICE ECHO-PLANAR IMAGING, WITH APPLICATIONS TO STUDY HUMAN BRAIN FUNCTIONS
(2016)Optimizing the speed of image acquisition in magnetic resonance imaging (MRI) is a significant consideration to reduce patient examination time and/or to increase temporal resolution in dynamic studies. The advancement of ... -
State of Health Estimation in Lithium-ion Batteries Using Experimental and Model Driven Approaches
(2024-05-10)Meeting the demand for clean, renewable energy in the future will require the use of batteries to meet power demand at times of low supply. Having batteries with a large enough capacity and power output to meet this ...
