MODELING THE BURNING OF COMPLICATED OBJECTS USING LAGRANGIAN PARTICLES

July 4, 2010
Author(s)
Kevin B. McGrattan, Randall J. McDermott, William E. Mell, Glenn P. Forney, Jason E. Floyd, Simo A. Hostikka
A methodology is described for representing complicated objects within a computational fluid dynamics model. These objects are typically collections of similar items that are too small to define on the numerical grid that is used to solve the governing

The Solidification of an Ideal Ternary Alloy in a Mushy Layer

March 24, 2010
Author(s)
Daniel M. Anderson, Geoffrey B. McFadden, Sam R. Coriell, Bruce Murray
We consider a model for the solidification of an ideal ternary alloy in a mushy layer that incorporates the effects thermal and solutal diffusion, convection and solidification. Our results reveal that although the temperature and solute fields are

Atmospheric Retention of Man-made CO 2 Emissions

June 8, 2009
Author(s)
Bert W. Rust
Rust and Thijsse have shown that global annual average temperature anomalies T(t i) vary linearly with atmospheric CO 2 concentrations c(t i). The c(t i) can be related to man-made CO 2 emissions F(t i) by a linear regression model whose solution vector

GaN nanowire carrier concentration calculated from light and dark resistance measurements

January 30, 2009
Author(s)
Lorelle Mansfield, Kristine A. Bertness, Paul T. Blanchard, Todd E. Harvey, Aric W. Sanders, Norman A. Sanford
We obtained limits on the carrier concentration and mobility of silicon-doped gallium nitride nanowires at room temperature with light and dark resistance data. Current-voltage measurements were performed on single-nanowire devices in the dark and under

Fiducial Intervals for the Magnitude of a Complex-Valued Quantity

December 19, 2008
Author(s)
Chih-Ming Wang, Hariharan K. Iyer
This paper discusses a fiducial approach for constructing uncertainty intervals for the distance between k normal means and the origin. When k=2 this distance is equivalent to the magnitude of a complex-valued quantity. Uncertainty intervals for the

Modeling Molecular Recognition: Theory and Application

October 16, 2008
Author(s)
K L. Mardis, R Luo, L David, M Potter, A J. Glemza, G F. Payne, M K. Gilson
Efficient, reliable methods for calculating the binding affinities of noncovalent complexes would allow advances in a variety of areas such as drug discovery and separation science. We have recently described a method that accommodates significant physical

… with technologies such as network communication, local computing, and distributed objects. This paper describes an …

Measuring the Overall Security of Network Configurations Using Attack Graphs

July 27, 2007
Author(s)
Lingyu Wang, Anoop Singhal, Sushil Jajodia
Today?s computer systems face sophisticated intrusions during which multiple vulnerabilities are combined for reaching an attack goal. To quantitatively assess the security of a network, one must first understand the interplay between vulnerabilities and

An Exact, Algebraic Solution for the Incubation Period of Superfill

January 1, 2004
Author(s)
Daniel Josell, Thomas P. Moffat, Daniel Wheeler
Recent publications have used the impact of area change coupled with conservation of adsorbed catalyst to quantify the superfill effect of bottom-up feature filling during electrodeposition and chemical vapor deposition. This work describes how that

Virtual Environment for Manipulating Microscopic Particles with Optical Tweezer

July 1, 2003
Author(s)
Thomas W. LeBrun, Kevin W. Lyons, Yong-Gu Lee
In this paper, we use virtual reality techniques to define an intuitive interface to a nanoscale manipulation device. This device utilizes optical methods to focus laser light to trap and reposition nano-to-microscopic particles. The underlying physics are

Technical Aspects of the Digital Library of Mathematical Functions

May 1, 2003
Author(s)
Bruce R. Miller, Abdou S. Youssef
The NIST Digital Library of Mathematical Functions (DLMF) Project, begun in 1997, is preparing a handbook and Web site intended for wide communities of users. The contents are primarily mathematical formulas, graphs, methods of computation, references, and

Moving Object Prediction for Off-road Autonomous Navigation

April 25, 2003
Author(s)
Rajmohan Madhavan, Craig I. Schlenoff
The realization of on- and off-road autonomous navigation of Unmanned Ground Vehicles (UGVs) requires real-time motion planning in the presence of dynamic objects with unknown trajectories. To successfully plan paths and to navigate in an unstructured

Probe-Force Calibration Experiments Using the NIST Electrostatic Force Balance

January 1, 2003
Author(s)
Jon R. Pratt, David B. Newell, John A. Kramar, J Mulholland, Eric P. Whitenton
The sensitivity of a piezoresistive cantilever force sensor has been determined by probing the weighing pan of the NIST prototype electrostatic force balance. In this experiment, micronewton contact forces between a force probe and the balance''s weighing

Noise-Parameter Uncertainties: A Monte Carlo Simulation

October 1, 2002
Author(s)
James P. Randa
This paper reports the formulation and results of a Monte Carlo study of uncertainties in noise-parameter measurements. The simulator permits the computation of the dependence of the uncertainty in the noise parameters on uncertainties in the underlying
