Community-Scale Fire Spread

July 1, 2002
Author(s)
Ronald G. Rehm, Anthony P. Hamins, Howard R. Baum, Kevin B. McGrattan, D D. Evans
This paper addresses community-scale fires, which have also been called urban/wildland interface or intermix fires. These fires arise when wildlandfires invade the built environment and attack structures as well as wildland fuels. The prediction of the

Comparison of Measured Optical Image Profiles of Silicon Lines with Two Different Theoretical Models

July 1, 2002
Author(s)
Richard M. Silver, Ravikiran Attota, Michael T. Stocker, Jay S. Jun, Egon Marx, Robert D. Larrabee, B Russo, M P. Davidson
In this paper we describe a new method for the separation of too-induced measurement errors and sample-induced measurement errors. We apply the method to standard overlay target configurations. This method is used to separate the effects of the tool and

Creation of a Molecular Condensate by Dynamically Melting a Mott Insulator

July 1, 2002
Author(s)
D Jaksch, V Venturi, J I. Cirac, Carl J. Williams, W.H. Zoller
We propose creation of a molecular Bose-Einstein condensate (BEC) by loading an atomic BEC into an optical lattice and driving it into a Mott insulator (MI) phase with exactly two atoms per site. Molecules in a MI state are then created under well defined

Crystal Structure of Ba 27 Fe 16 Ti 33 O 117

July 1, 2002
Author(s)
T Siegrist, Terrell A. Vanderah, C Svensson, Robert S. Roth
Single-crystal X-ray diffraction studies indicate that the compound Ba 27Fe 16Ti 33O 117- crystallizes in the rhombohedral space group R-3m, with a hexagonal unit cell a=5.7400(8) , c=127.11(3) ; Z=1.5. The arrangement may be described as a 54-layer (54L)

Direct Measurement of the Reaction Front in Chemically Amplified Photoresists

July 1, 2002
Author(s)
Eric K. Lin, Sushil K. Satija, Wen-Li Wu, Christopher L. Soles, D L. Goldfarb, B C. Trinque, S D. Burns, Ronald L. Jones, Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, M Angelopoulos, C G. Willson
The continuing drive by the semiconductor industry to fabricate smaller structures with photolithography will soon require dimensional control at length scales, (2 to 5) nm, comparable to the size of the polymeric molecules in the materials used to pattern

Document Understanding Conferences Website

July 1, 2002
Author(s)
Ellen M. Voorhees
This paper demonstrates that, for large-scale tests, the match and non-match similarity scores have no specific underlying distribution function. The forms of these distribution functions require a nonparametric approach for the analysis of the fingerprint

Dynamic Range Limitations in Phase Doppler Interferometry Measurements

July 1, 2002
Author(s)
J F. Widmann, Cary Presser, Stefan D. Leigh
It has been well established that the dynamic range of phase Doppler interferometry (PDI) size measurements is limited by the photomultiplier tubes (PMT). A statistical method is presented to overcome this limitation by combining data sets collected over

Dynamics in a Two-Level Atom Magneto-Optical Trap

July 1, 2002
Author(s)
X Xu, T Loftus, M J. Smith, John L. Hall, Alan Gallagher, Jun Ye
Alkaline earth metal atoms present an ideal platform for exploring magneto-optic trap (MOT) dynamics, enabling unique and definitive tests of laser cooling and trapping mechanisms. We have measured the trapping beam intensity, detuning, magnetic-field

Fabricating Planar Nanoparticle Assemblies With Number Density Gradients

July 1, 2002
Author(s)
R R. Bhat, Daniel A. Fischer, Jan Genzer
We report on preparing assemblies of gold nanoparticles with continuous gradients in number density on flat silica-covered substrates. The methodology consists of: i) first forming a one dimensional molecular gradient of amino groups (-NH2) on the

Fabrication and Characterization of In-Situ Grown Epitaxial Ba 1-x Sr x Ti0 3 ) Composition Spreads

July 1, 2002
Author(s)
K S. Chang, M A. Aronova, O Famodu, Jason Hattrick-Simpers, S E. Lofland, Ichiro Takeuchi, C J. Lu, Leonid A. Bendersky, H C. Chang
We have used our combinatorial pulsed laser deposition system to in-situ fabricate epitaxial Ba(sub1-x)Sr(sub x)Ti)(sub 3) thin film composition spreads on (100) LaAl0(sub3) substrates. Multimode quantitative microwave microscopy was used to perform

Fire Research: Providing New Tools for Fire Investigation

July 1, 2002
Author(s)
Daniel M. Madrzykowski
Researchers at the National Institute of Standards and Technology's (NIST) Building and Fire Laboratory (BFRL) are working with the U.S. Fire Administration (USFA); the Bureau of Alcohol, Tobacco and Firearms (ATF); and the U.S. Department of Justice to

Fire Safety Research at NIST

July 1, 2002
Author(s)
Anthony P. Hamins
The Fire Research Division is one of four Divisions in the Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST). The Division is composed of approximately 58 full time employees, 25 guest scientists and

First Results From the Updated NIST/DARPA EUV Reflectometry Facility

July 1, 2002
Author(s)
S Grantham, Charles Tarrio, M B. Squires, Thomas B. Lucatorto
Currently the most demanding application of extreme-ultraviolet (EUV) optics is in lithography. A commercial extreme-ultraviolet stepper will likely have six or more normal-incidence reflective optics, and the largest of these will be tens of cm in
