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 ... -
A State of Unfairs: A Case Study Concerning Respect for Teachers in Oklahoma
(2016-12)The purpose of this research study is to examine if and how Oklahoma teachers are disrespected within their profession. This study incorporates an online survey and in-depth interviewing to attempt to address the ... -
A STATE VECTOR AUGMENTATION METHOD FOR INCLUDING VELOCITY INFORMATION IN THE LIKELIHOOD FUNCTION OF THE SIR VIDEO TARGET TRACKING FILTER
(2016)This thesis is focused on visual target tracking. Visual target tracking has been widely studied. The main idea is to be able to determine the target's location from a video sequence. Techniques such as the Kalman Filter ... -
State-of-the-Art Scanning Electron Microscope for Multiple Applications: From Solar-Cells to Megaspores
(2016-05)The University of Oklahoma (OU) recently acquired a Zeiss Neon, a dual beam SEM/FIB Cross beam machine. This thesis focuses on its utilization via two independent projects, one involving the characterization of solar-cells ... -
Station management perceptions of barter syndication : a pilot study
(1992)Television stations may obtain off-network and other syndicated programing for little or no cash outlay. The practice of barter is used in nearly every commercial television station. In this pilot study, the barter industry, ... -
A Statistical Approach to Diagnosing Storm Mode
(2021-12-17)Determining storm mode (linear or isolated) is a crucial component of any severe weather forecast. Isolated storms are associated with a greater likelihood of significant (EF2+) tornadoes and very large (2”+) hail, while ...
