    • A Confidence-Prioritization Approach to Data Processing in Noisy Data Sets and Resulting Estimation Models for Predicting Streamflow Diel Signals in the Pacific Northwest

    • Gustafson, Nathaniel Lee

    • Streams in small watersheds are often known to exhibit diel fluctuations, in which streamflow oscillates on a 24-hour cycle. Streamflow diel fluctuations, which we investigate in this study, are an informative indicator of environmental processes....

    • A Five-Zone Model for Direct Injection Diesel Combustion

    • Asay, Rich 1973-

    • Recent imaging studies have provided a new conceptual model of the internal structure of direct injection diesel fuel jets as well as empirical correlations predicting jet development and structure. This information was used to create a diesel...

    • A Generalized Two-Dimensional Model to Reconstruct the Impact Phase in Automobile Collisions

    • David, Regis Agenor 1981-

    • Automobile accident reconstruction has been facilitated by the development of computer based modules to allow evaluation of evidence gathered at the accident scenes. Although the computer modules are based in fundamental physical laws, an...

    • A New Model for Aqueous Electrolyte Solutions Near the Critical Point of Water Incorporating Aqueous Reaction Equilibria

    • Peterson, Craig J 1979-

    • Aqueous electrolyte solutions at temperature and pressure conditions near the critical point of water are difficult to describe using traditional equations of state based upon the excess Gibbs energy. Models based upon the residual Helmholtz...

    • A Novel Use of Digoxin Immune Fab Fragment in Identification and Isolation of an Endogenous Digitalis-like Factor Found in Preeclampsia

    • Hopoate-Sitake, Moana Lee

    • The mechanisms mediating the hypertension of preeclampsia (PE) are unclear. Endogenous digitalis-like factors (EDLFs) are specific sodium pump (SP) inhibitors implicated in essential and experimental hypertension, but they have not been fully...

    • A Numerical Model of the Friction Stir Plunge

    • McBride, Stanford Wayne 1980-

    • A Lagrangian finite-element model of the plunge phase of the friction stir welding process was developed to better understand the plunge. The effects of both modeling and experimental parameters were explored. Experimental friction stir plunges...

    • A PAM Decomposition of Weak CPM

    • Wardle, Mason B 1977-

    • The Enhanced Flight Termination System uses weak CPM as its modulation scheme and a limiter-discriminator as its demodulation scheme. A PAM representation of weak CPM was developed which representation provided the necessary componenents to build a...

    • A Provacative Test to Determine Brain Compliance in the Management of Patients with Hydrocephalus

    • Manwaring, Preston K 1978-

    • Non-invasive techniques to explore intracranial compliance and pressure have been extensively explored in recent years. Previous techniques have used expensive technologies to make these measurements, often with difficulty. We present a novel,...

    • A Qualitative Method for Dynamic Transport Selection in Heterogeneous Wireless Environments

    • Duffin, Heidi R 1978-

    • Computing devices are commonly equipped with multiple transport technologies such as IrDA, Bluetooth and WiFi. Transport switching technologies, such as Quality of Transport (QoT), take advantage of this heterogeneity to keep network sessions...

    • A Wideband Precision Quadrature Phase Shifter

    • Noall, Steve T

    • A new circuit is proposed that uses an RC-CR filter in a feedback configuration to achieve a wideband precision quadrature phase shift with constant amplitude response. Such a circuit can be used to perform image rejection in a low IF receiver...

    • Aerial Recovery of Micro Air Vehicles: Orbit Estimation and Tracking

    • Carlson, Daniel Clarke 1983-

    • Aerial recovery of autonomous micro air vehicles (MAVs) presents many unique challenges due to the difference in size and speed of the recovery vehicle and MAV. This thesis presents algorithms to enable an autonomous MAV to estimate the orbit of a...

    • An Adaptive Bayesian Approach to Bernoulli-Response Clinical Trials

    • Stacey, Andrew W 1982-

    • Traditional clinical trials have been inefficient in their methods of dose finding and dose allocation. In this paper a four-parameter logistic equation is used to model the outcome of Bernoulli-response clinical trials. A Bayesian adaptive design...

    • An Adaptive Bayesian Approach to Dose-Response Modeling

    • Leininger, Thomas J 1984-

    • Clinical drug trials are costly and time-consuming. Bayesian methods alleviate the inefficiencies in the testing process while providing user-friendly probabilistic inference and predictions from the sampled posterior distributions, saving...

    • An Analysis of the Influence of Lesson Study on Preservice Secondary Mathematics Teachers' View of Self-as Mathematics Expert

    • Stafford, Julie 1976-

    • This research seeks to investigate the influence of lesson study on preservice secondary mathematics teachers' view of self as mathematics expert. The study acknowledges the commonly held belief that prospective mathematics teachers have that they...

    • An Investigation of Positive Engagement, Continuously Variable Transmissions

    • Dalling, Ryan R 1982-

    • A Positive Engagement, Continuously Variable Transmission (PECVT) allows for a continuously variable transmission ratio over a given range using positively engaged members, such as gear teeth, to transmit torque. This research is an investigation...

    • An Optimization-Based Method of Traversing Dynamic s-Pareto Frontiers

    • Lewis, Patrick K.

    • The use of multiobjective optimization in identifying systems that account for changes in customer needs, operating environments, system design concepts, and analysis models over time is generally not explored. Providing solutions that anticipate,...

    • Analysis of Clinically Important Compounds Using Electrophoretic Separation Techniques Coupled to Time-of-Flight Mass Spectrometry

    • Peterson, Zlatuse Durda 1972-

    • Capillary electrophoretic (CE) separations were successfully coupled to time-of-flight mass spectrometric (TOFMS) detection for the analysis of three families of biological compounds that act as mediators and/or indicators of disease, namely,...

    • Analysis of Near-Infrared Phase Effects on Biometric Iris Data

    • Stevenson, Brady Roos 1974-

    • The purpose of this research is to ascertain potential iris scan data variations from near infrared waves derived from fluorescent illumination. Prior studies of iris data variances from infrared wave interference of halogen, incandescent, and...

    • Association Between Academic Performance and Electrocortical Processing of Cognitive Stimuli in College Students

    • Wolf, Mary Menn

    • Because event-related potentials (ERPs) can reflect individual differences in intellectual ability, individual differences in college grade-point average (GPA) may be associated with specific individual ERP waves, such as the P300. However, P300...
