Development of predictive modeling tools for estimating fuel use and emission rates for heavy-duty diesel construction equipment
(2014-05)
Heavy-duty diesel (HDD) construction equipment consumes a substantial amount of fuels and consequently emits a substantial amount of pollutants into the environment. This dissertation presents methodologies for estimating ...
Molecular characterization of aromatic hydrocarbon degradation in extreme halophiles

(2014-05)
Preparing healthcare providers for the realities of entry-level professional practice is critical. To this end, the traditional medical education model for a variety of disciplines mandates a period of supervised student ...
Accelerating convergence of leapfrogging optimization - Applications to nonlinear process modeling and nonlinear model predictive control
(2014-07)
Conventionally used optimization methods in chemical engineering applications such as linear programming (LP), Levenberg-Marquardt and sequential quadratic programming (SQP) handle nonlinear objective function (OF) surfaces ...
How pre-engagement factors and service product attribute complexity impact customer tenure with a retailer
(2014-12)
The purpose of this research is to look at how various cultural dimensions - power distance, uncertainty avoidance, and individualism/collectivism - are related to the actual tenure of a customer with a retail service ...
Antioxidant capacity, phenolic and volatile compound composition of blackberry wines produced using Korean traditional wine-making techniques
(2014-07)
This research project was designed to evaluate the winemaking potential of `Natchez' and `Triple Crown' blackberries grown in Oklahoma as well as to examine the measurable basic physical properties and potential health-benefits ...
Understanding the formation and maintenance of the conservative identity in Oklahoma
(2014-07)
This qualitative study explored how Oklahoma conservatives constructed and understood their conservative identities, as well as the ideas and people they attributed as influencing their identities. Drawing upon ethnographic ...
