Coalescence of Single Photons Emitted by Disparate Single Photon Sources: The Example of InAs Quantum Dots and Parametric Down-Conversion Sources

October 5, 2011
Author(s)
Sergey V. Polyakov, Andreas Muller, Alexander E. Ling, Natalia B. Rutter, Edward B. Flagg, Edward Van Keuren, Alan L. Migdall, Glenn S. Solomon
In quantum mechanics, particles in identical states are indistinguishable, giving rise to effects with no classical analog. Single photons produced by fundamentally dissimilar physical processes will in general not be indistinguishable. We show how photons

COMPARISON OF TWO DIMENSION-REDUCTION METHODS FOR NETWORK SIMULATION MODELS

October 5, 2011
Author(s)
Kevin L. Mills, James J. Filliben
Experimenters characterize the behavior of simulation models for data communications networks by measuring multiple responses under selected parameter combinations. The resulting multivariate data may include redundant responses reflecting aspects of a

Effect of Moisture on Copolymer Fibers based on 5-amino-2-(p-aminophenyl)-benzimidazole

October 4, 2011
Author(s)
Guillaume Messin, Stephanie S. Watson, Amanda L. Forster, John R. Sieber
In recent years, there has been concern in the soft body armor community that copolymer fibers based on 5-amino-2-(p-aminophenyl)-benzimidazole can release hydrochloric acid, which could potentially be detrimental to other fibers that might come in contact

Predicting Human Behavior during Fires

October 4, 2011
Author(s)
Erica D. Kuligowski
Evacuation models, including engineering hand calculations and computational tools, are used to evaluate the level of safety provided by buildings during evacuation. Building designs and occupant procedures are based on the results produced from these

Source Code Security Analysis Tool Test Plan

October 4, 2011
Author(s)
Hsiao-Ming M. Koo, Romain Gaucher, Charline Cleraux, Jenise Reyes Rodriguez
This document provides a set of metrics, including test suites and methods, to determine how well a particular source code security analysis tool conforms to the requirements specified in Source Code Security Analysis Tool Functional Specification Version

DNA ENTROPOPHORESIS: A BALANCE OF ENTROPY AND DIFFUSION IN COMPLEX NANOCONFINEMENT

October 3, 2011
Author(s)
Samuel Stavis, Jon Geist, Michael Gaitan, Laurie E. Locascio, Elizabeth Strychalski
Entropophoresis - motion caused by an entropy gradient - is a novel nanofluidic method to direct the self-transport of biopolymers that established a new paradigm of nanofluidic functionality with broad relevance to lab-on-a-chip technol-ogy. Here, the

Metamodels towards Improved Domain Modeling for Semantic Inferencing

October 3, 2011
Author(s)
Paul W. Witherell, Anantha Narayanan Narayanan, Jae H. Lee, Sudarsan Rachuri
As information requirements have increased, domain models have become increasing complex and difficult to manage. Though domain-specific languages have been developed for domain experts, increasing their expressivity and decreasing their complexity, their

SteelVis User's Guide

October 3, 2011
Author(s)
Robert R. Lipman
This guide describes how to use SteelVis and its associated programs. SteelVis has two main functions: (1) to translate a CIS/2 (CIMsteel Integration Standards) file into an interactive 3D model in the form of a VRML (Virtual Reality Modeling Language)

SWIR calibration of spectralon reflectance factor

October 3, 2011
Author(s)
Catherine C. Cooksey, Georgi T. Georgiev, James J. Butler, Leibo Ding, Kurtis J. Thome
Satellite instruments operating in the reflective solar wavelength region require accurate and precise determination of the Bidirectional Reflectance Factor (BRF) of laboratory-based diffusers used in their pre-flight and on-orbit radiometric calibrations

Carbon nanotube arrays for absolute IR and THz radiometry

October 2, 2011
Author(s)
John H. Lehman, Kerry N. Betz, Erich N. Grossman
We have assembled and evaluated a novel electrically calibrated thermopile having an array of 1.5 mm long multiwalled carbon nanotubes as the radiation absorber. We find very low reflectance at the 390 υm laser wavelength and excellent agreement between

Alternate Smoldering Ignition Sources: A Literature Review with Analysis

October 1, 2011
Author(s)
Richard G. Gann, Amanda P. Robbins
Current existing and proposed U.S. flammability standards for soft furnishings such as mattresses and upholstered furniture specify a “standard” cigarette as the ignition source in smoldering resistance performance tests. With the prevalence of reduced

High Frequency Characterization of Contact Resistance and Conductivity of Platinum Nanowires*

October 1, 2011
Author(s)
Kichul Kim, Paul Rice, Thomas M. Wallis, Dazhen Gu, SangHyun S. Lim, Atif A. Imtiaz, Pavel Kabos, Dejan Filipovic
Abstract— Individual platinum (Pt) nanowires (NWs) with 100 nm and 250 nm diameters, embedded in coplanar waveguide (CPW) structures are investigated. Three approaches for characterization of their contact resistance and conductivity at high frequencies

The Effect of Gravity on the Resolution of Small-Angle Neutron Diffraction Peaks

October 1, 2011
Author(s)
David F. Mildner, John G. Barker, Steven R. Kline
The resolution ellipses for neutron diffraction peaks at small vectors lie along lines that point to a position vertically above the beam center. This gravity effect is only noticeable for neutron beams at long wavelenghts and with large wavelength spreads
