Stabilization of Ponca City shale.
(1982)
Preliminary characterization of the Ponca City shale for highway construction purposes, and its amenability to lime, cement, fly ash and conjunctive stabilization were investigated in this study. After numerous screening ...
Development of a novel apparatus to determine the multiaxial tensile failure criteria for ultra-high performance concretes
(2021-12)
The use of ultra-high performance concrete (UHPC), a stronger and more durable class of concrete, has increased in recent years. Large-scale production has been limited due to the cost of proprietary UHPC products, but the ...
Iron Transport and Removal Dynamics in the Oxidative Units of a Passive Treatment System
(2016-12)
Abstract
Mine drainage is threat to water systems in legacy mining districts as elevated concentrations of dissolved iron, sulfate, and trace metals have an unmitigated impact on water quality. Changes in pH due to ...
Determination of volatile hydrocarbon emissions from land treatment of petroleum oily sludges /
(1984)
Experimental soil-disposal tests were conducted in the laboratory in a controlled environment and on the field plots. Approximately 4792 kg sludge was spread on the six experimental plots in the field over a six-month test ...
DEVELOPMENT AND EVALUATION OF AN ADVANCED REGIONAL AND GLOBAL HYDROLOGICAL PREDICTION SYSTEM ENABLED BY SATELLITE REMOTE SENSING, NUMERICAL WEATHER FORECASTING, AND ENSEMBLE DATA ASSIMILATION
(2013-12)
This dissertation advanced the traditional hydrological prediction via multi-sensor satellite remote sensing products, numerical weather forecasts and advanced data assimilation approach in sparsely gauged or even ungauged ...
Anisotropic poromechanics of the wellbore coupled with thermal and chemical gradients.
(2002)
A generalized anisotropic porothermoelastic formulation incorporating fully coupled thermo-hydro-mechanical response of saturated porous media is developed. Governing equations are tailored for transversely isotropic media ...
Development of a Web-based infrastructure management system for Oklahoma's general aviation airports, and, Exploring the use of spectral analysis of surface waves and impulse response for pavement health monitoring.
(2007)
The transportation infrastructure of the United States consumes over 17% of its Gross National product annually and is currently valued at $1.75 trillion. With the interstate system now 50 years old, the emphasis of the ...
MECHANISTIC INPUT PARAMETERS AND MODEL CALIBRATION FOR DESIGN AND PERFORMANCE EVALUATION OF FLEXIBLE PAVEMENTS IN OKLAHOMA
(2017-12)
The Mechanistic-Empirical Pavement Design Guide (MEPDG) – a product of research and experience involving more than 20 years of traffic, climate and materials data from different regions in the U.S. – has elevated pavement ...
Characterization of cement-kiln-dust stabilized base/subbase aggregate.
(1998)
In this study, a laboratory testing program was undertaken to determine the resilient modulus and other properties of a cement-kiln-dust (CKD) stabilized aggregate that are important to the design and rehabilitation of ...
Quantification of chlorophyll in small reservoirs using airborne video imagery.
(1998)
The primary objective of this study was to develop a rapid, economic method of assessing water quality and productivity in surface impoundments. Airborne video cameras equipped with narrow band filters were used to assess ...
