Compound flooding in eastern North Carolina: Understanding stakeholder perceptions and needs

March 29, 2021
Author(s)
Scott Curtis, Jamie Kruse, Anuradha Mukherji, Jennifer Helgeson, Kelley DePolt, Philip Van Wagoner, Ausmita Ghosh
While our scientific understanding of compound flood risk has made great strides in recent years, there is a lack of studies related to stakeholder awareness of the non-linear combination of pluvial, fluvial, and tidal flooding, which often occur in

Noble-metal dark-edge fermiology: core-hole memory and the "Zeeman Auger" effect

January 12, 2022
Author(s)
Eric L. Shirley, Joseph Woicik, Conan Weiland, Ahmed Rumaiz, Charles Cardot, Joshua Kas, John Rehr
Gold and platinum have the face-centered-cubic crystal structure, are considered noble metals, and differ by one in atomic number. Near-edge M4,5 x-ray absorption and resonant M4,5N6,7N6,7 Auger spectroscopy reveal "dark" edges and a photon-energy

Learning to Recognize Distributional Functions

October 12, 2021
Author(s)
J E. Devaney, L Hunter, James J. Filliben
This paper introduces a novel methodology that enables recognition of distributional functions without doing a fit of the data to the distribution. This methodology combines the technique of equation signatures, which uses coefficient independent

Performance of Coriolis Meters in Transient Gas Flows

Jodie G. Pope, John D. Wright
… discharged 3 kg of helium in 3 minutes at flows between 45 g/s and 10 g/s (Re = 6.0 X 105 to 1.4 X 106) through the coriolis meters and the TFF’s standards. … level) for totalized mass during this cascade fill was 0.45 %. For the same simulated cascade fill, both evaluated …

Bicubic B-Spline Surface Approximation of Invariant Tori

October 20, 2010
Author(s)
Sita Ramamurti, David E. Gilsinn
The invariant torus of a coupled system of Van der Pol oscillators is approximated using bicubic B-splines. The paper considers the case of strong nonlinear coupling. In particular, the shapes of invariant torii for the Van der Pol coupling parameter $

A Novel Multiaxial Wear Tester for Accelerated Testing of Materials

December 1, 1999
Author(s)
M C. Shen, Stephen M. Hsu, John A. Tesk, A Christou
A versatile wear tester has been designed and built. The initial study showed that that with this tester, tes procedures can be developed to achieve clinically relevant simulations in a short time. With the continuously monitored force traces, this tester
