Model for Reversible Nanoparticle Assembly in a Polymer Matrix

January 8, 2008
Author(s)
Andrew Rahedi, Jack F. Douglas, Francis W. Starr
The clustering of nanoparticles (NP) within solutions and polymer melts depends sensitively on the strength and directionality of the NP interactions involved, as well as the molecular geometry and interactions of the dispersing fluids. Since clustering

A Common Operator Control Unit Color Scheme for Mobile Robots

December 28, 2007
Author(s)
Michael O. Shneier, Roger V. Bostelman, James S. Albus, William P. Shackleford, Tommy Chang, Tsai Hong Hong
… a very difficult experience evalu-ating what the robot was computing based on stereo image, instrumented bumper, and …

Development of the Aerosol Particle Mass Analyzer

October 17, 2007
Author(s)
Nobuhiko Fukushima, Naoko Tajima, Kensei Ehara, Hiromu Sakurai, Kevin Coakley
The Aerosol Particle Mass Analyzer (APM), can classify particles according to their mass-to-charge ratio. The utility of the APM has been confirmed; the APM has been applied to atmospheric aerosol research and engine exhaust measurements. The operating

Federal Building and Fire Safety Investigation of the World Trade Center Disaster: Final Report of the National Construction Safety Team on the Collapses of the World Trade Center Towers (NIST NCSTAR 1)

December 1, 2005
Author(s)
Sivaraj Shyam-Sunder, Richard G. Gann, William L. Grosshandler, Hai S. Lew, Richard W. Bukowski, Fahim Sadek, Frank W. Gayle, John L. Gross, Therese P. McAllister, Jason D. Averill, James R. Lawson, Harold E. Nelson, Stephen A. Cauffman
This is the final report on the National Institute of Standards and Technology (NIST) investigation of the collapse of the World Trade Center (WTC) towers, conducted under the National Construction Safety Team Act. This report describes how the aircraft

What a User Should Know When Selecting an Evacuation Model.

December 1, 2005
Author(s)
Erica D. Kuligowski, Steve M. Gwynne
In recent years, evacuation models have been increasingly applied in an attempt to understand the outcome of emergency egress scenarios. This has been due to the increased use of performance-based design and the availability of cost-effective, high

Experimental Determination of Electron Inelastic Mean Free Paths in 13 Elemental Solids in the 50 eV to 5000 eV Energy Range by Elastic-Peak Electron Spectroscopy

May 1, 2005
Author(s)
S Tanuma, T Shiratori, Tetsuya Kimura, K Goto, S Ichimura, Cedric J. Powell
We have determined electron inelastic mean free paths (IMFPs) in C (graphite), Si, Cr, Fe, Cu, Zn, Ga, Mo, Ag, Ta, W, Pt and Au by elastic-peak electron spectroscopy (EPES) using Ni as a reference material for electron energies between 50 eV and 5000 eV

Monte Carlo Strategies for Simulations of Electron Backscattering from Surfaces

May 1, 2005
Author(s)
Aleksander Jablonski, Cedric J. Powell, S Tanuma
Reliable algorithms for simulation of electron trajectories in solids are needed for quantification of Auger electron spectroscopy, particularly for determination of the backscattering factor (BF). The computational schemes for this purpose should be

Assembled Designs for Estimation of Location, Dispersion, and Random Effects

March 1, 2005
Author(s)
A Aviles, B E. Ankenman, J C. Pinheiro
In many experimental settings, different types of factors affect the measured response. The factors that can be set independently of each other are called crossed factors. Nested factors cannot be set independently because the level of one factor takes on

Linewidth Measurement from a Stitched AFM Image

January 1, 2005
Author(s)
Joseph Fu, Ronald G. Dixson, Ndubuisi G. Orji, Theodore V. Vorburger, C Nguyen
Image stitching is a technique that combines two or more images to form one composite image, which provides a field of view that the originals cannot. It has been widely used in photography, medical imaging, and computer vision and graphics. For such

XML Schema Design Quality Test Requirements

October 1, 2004
Author(s)
Boonserm Kulvatunyou, KC Morris
Consistent design of XML schema within an organization or single integration project can reduce the number and the severity of interoperability problems. In addition, this consistency makes the XML schema easier to extend, understand, implement, and

Fire Safety of Passenger Trains. Phase 3. Evaluation of Fire Hazard Analysis Using Full-Scale Passenger Rail Car Tests (NISTIR 6563)

April 1, 2004
Author(s)
Richard D. Peacock, Jason D. Averill, Daniel M. Madrzykowski, D W. Stroup, Paul A. Reneke, Richard W. Bukowski
Fire safety is an area of particular interest for both conventional intercity and commuter passenger trains, and new high-speed trains. A systems approach to fire safety addresses passenger rail car design and materials, detection and suppression

Spatial Methods for Event Reconstruction in CLEAN

April 9, 2003
Author(s)
Kevin Coakley, D N. Mckinsey
In CLEAN (Cryogenic Low Energy Astrophysics with Noble gases), a proposed neutrino and dark matter detector, background discrimination is possible if one can determine the location of an event with high accuracy. Here, we develop spatial methods for event

Face Recognition Vendor Test 2002: Evaluation Report

March 1, 2003
Author(s)
P J. Phillips, Patrick J. Grother, Ross J. Micheals, D M. Blackburn, Elham Tabassi, M Bone
The Face Recognition Vendor Test (FRVT) 2002 is an independently administered technology evaluation of mature face recognition systems. FRVT 2002 provides performance measures for assessing the capability of face recognition systems to meet requirement for
