Objective Characterization of In-line Phase Contrast X-ray Imaging Prototype Using a Mid-energy Beam
(2019-08)The purpose of the research presented in this thesis is the characterization of an in-line phase contrast x-ray imaging prototype operating at mid-energy, and to compare the data to that of high energy imaging with the ... -
Observations and Simulations of a Multistatic Weather Radar Network
(2022-05)Multistatic radar architectures have the potential to provide a cost-effective source of 3D wind information from both operational and research radars, owing to a system design of one transmitter and several receivers. A ... -
Observations of Cold Front Features at High Spatiotemporal Resolution Using the Atmospheric Imaging Radar
(2016-08-12)Over the past 40+ years, cold front vertical structure has been studied for the purpose of increased understanding of convection initiation and aviation safety. Traditional scanning radars tend to not be well-suited for ... -
Observations of Mars analogous basalt in near saturated brines
(2020-05)The Mars 2020 rover and the ExoMars rover will include a Raman spectrometer as part of the suite of instruments onboard the rovers and will be the first times a Raman spectrometer will take direct measurements on the surface ... -
Observations of Tropical Cyclone Vortex Rossby Waves and Their Role in Inner Core Rainbands
(2016-08-12)Vortex Rossby Waves (VRWs) are hypothesized to exist in tropical cyclones (TCs), acting as an axisymmetrizing mechanism to the inner core TC flow and restored by the radial gradient of storm vorticity. In addition, they ... -
Observing system simulation experiment studies on the use of small UAV for boundary-layer sampling
(2018)A long-desired component to the U.S. operational observing systems is the capability to measure vertical profiles of wind, temperature and moisture in the lower troposphere at high spatial and temporal resolution. This ... -
Observing System Simulation Experiments on Assimilation of Multistatic Passive Radar Network Observations into the Warn-On Forecast System to Improve Short-Term Prediction of Thunderstorm Hazards
(2022-12-16)The Warn-on-Forecast System (WoFS) assimilates radar and satellite observations to produce initial conditions for short-term forecasts of individual convective storms. The accuracy of the WoFS analysis is a function of the ... -
Observing System Simulation Experiments Using Small Unmanned Aerial Vehicles in Various Configurations to Improve High-Resolution Forecasts of Convection
(2021)There has been a lot of interest and development of small Unmanned Aerial Vehicles (sUAVs) to obtain atmospheric measurements for research and operations. Some have proposed a 3D Mesonet concept to add vertical profiling ... -
OIL POTENTIAL OF THE ASQUITH MARKER, LEWIS SHALE, GREATER GREEN RIVER BASIN, WYOMING.
(2016-05-13)Large volumes of gas and some oil have been produced from the Cretaceous Lewis Shale, and it is often considered a regional source of gas in the Greater Green River Basin. However, the Lewis Shale has never been studied ... -
Oklahoma and World War I: Over Here and Over There
(2023-12-15)The State of Oklahoma, one of the United States’ newest states, entered the First World War, along with the rest of the nation in April 1917. This study elucidates the role of Oklahoma’s participation in the United States ... -
The Oklahoma Canon: A Need for Multicultural Literature in the ELA Classroom
(2020)This study examines the frequency with which Oklahoma English teachers include multicultural literature into their curriculum. In addition, this study explores teachers’ attitudes and beliefs toward multicultural literature, ... -
Oklahoma Earthquakes and Their Effects on Highway Bridges
(2017-05-13)Oklahoma is presently experiencing a higher rate of earthquake activity than historically observed. Historical data on earthquake-induced damage to Oklahoma bridges is limited, so the Oklahoma Department of Transportation ... -
OKLAHOMA EDUCATION BUDGET CUTS: PERSPECTIVES OF EARLY CHILDHOOD EDUCATORS IN LOW-INCOME SCHOOLS
(2017)This study investigated the lived experiences of early childhood educators in low-income Oklahoma public schools during a time of budget crisis. The state’s education system is floundering in terms of funding with an ... -
The Oklahoma Hispanic Cultural Center: A History of the Latina/o Community in Oklahoma City
(2021-05-16)The purpose of this thesis is to reinsert the Latina/o community and the Oklahoma Hispanic Cultural Center into the history of Oklahoma. The Latina/o community has contributed to the overall history of Oklahoma. However, ... -
ON THE FATE OF THE FRACTURING FLUID AND ITS IMPACT ON LOAD RECOVERY AND WELL PERFORMANCE
(2016-08-01)The complexity of the shale system coupled with the mystery of low fracturing fluid recovery has puzzled many researchers. Field reports from hydraulic fracturing operations performed on shale formations have highlighted ... -
On the Reciprocal Nature of Active Publics in Divisive Social Issues: Opinion Climate and the Road to Stalled Social Conversations
(2022-05-13)This thesis investigated active publics’ communicative course of action by evaluating variables such as individual ethical orientation and perceived opinion climate, providing insight on the justification of the communicative ... -
On the use of Odonata as ecological indicators
(2018)The insect order Odonata, the dragonflies and damselflies, is unique to use as an ecological indicator for water quality because of its close relationship with aquatic ecosystems and relative ease of observation and ... -
