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

Fragility Curves, Damage Matrices, and Wind-Induced Loss Estimation

June 1, 2002
Author(s)
James J. Filliben, K Gurley, J P. Pinelli, Emil Simiu, M Subramanian
This note presents a conceptual framework for the definition of basic damage states and of the corresponding fragility curves and conditional probabilities, and its use for the estimation of damage matrices. The framework is designed with two

Non-Equilibrium Pattern Formation in the Crystallization of Polymer Blend Films

April 1, 2002
Author(s)
V Ferreiro, Jack F. Douglas, James A. Warren, Alamgir Karim
The crystallization of polymeric and metallic materials normally occurs under conditions far from equilibrium. The morphologies formed reflect a competition between order associated with the symmetries of the equilibrium crystal geometry and disorder

Intrinsic Viscosity and the Electric Polarizability of Arbitrarily Shaped Objects

December 1, 2001
Author(s)
M Mansfield, Jack F. Douglas, Edward Garboczi
The problem of calculating the electrical polarizability tensor αe of objects of arbitrary shape has been reformulated in terms of path integration and implemented computationally. The method simultaneously yields the electrostatic capacity C and the

The Conformational Structures and Dipole Moments of Ethyl Sulfide in the Gas Phase

August 1, 2001
Author(s)
David F. Plusquellic, R D. Suenram, B Mate, J O. Jensen, A C. Samuels
The pure rotational spectrum of ethyl sulfide has been measured from 12 gHz to 21 GHz in a 1 K Jet-cooled expansion using a Fourier-transform microwave (FTMW) spectrometer. Prominent features in the spectrum are assigned to transitions from three

CASSCF Investigation of Electronic Excited States of 2-Aminopurine

January 11, 2001
Author(s)
E L. Rachofsky, J B. Ross, Morris Krauss, R Osman
2-aminopurine is a highly fluorescent analog of adenine that can be incorporated synthetically into DNA with little perturbation of the native double-helical structure. The sensitive dependence of the quantum yield of this fluorophore on nucleic acid

Full-Scale House Fire Experiment for InterFIRE VR, May 6, 1998. Report of Test.

April 10, 2000
Author(s)
Anthony D. Putorti Jr., Jay A. McElroy
A public/private partnership involving multiple federal agencies and private industry was assembled to develop a comprehensive fire investigation training tool. The partnership consisted of the following federal agencies: the Bureau of Alcohol, Tobacco and

Mosquito Noise in MPEG-compressed Video: Test Patterns and Metrics

January 1, 2000
Author(s)
Charles D. Fenimore, John M. Libert, Peter Roitman
Mosquito noise is a time dependent video compression impairment in which the high frequency spatial detail in video images having crisp edges is aliased intermittently. A new synthetic test pattern of moving spirals or circles is described which generates

Volume 4, The 1997 Prelaunch Radiometric Calibration of Sea WiFS

April 1, 1999
Author(s)
Bettye C. Johnson, Howard W. Yoon, Sally S. Bruce, Ping-Shine Shaw, E A. Thompson, S B. Hooker, R Eplee, R Barnes, S Maritorena, J Mueller
The Sea-viewing Side Field-of-view Sensor (SeaWiFS) was originally calibrated by the instrument's manufacturer, Santa Barbara Research Center (SBRC), in November 1993. In preparation for an August 1997 launch, the Sea WiFS Project and the National

Is Your Scanning Electron Microscope Hi-Fi?

December 7, 1996
Author(s)
Andras Vladar, Michael T. Postek, S Davilla
The scanning electron microscope (SEM) historically has been used mainly as an image-producing device and, in spite of certain obvious and sometimes serious electronics problems, serves in this function as an acceptable and effective instrument for many

Suppression of Engine Nacelle Fires (NIST SP 890)

November 1, 1995
Author(s)
Anthony P. Hamins, Thomas G. Cleary, P. Borthwick, N Gorchkov, Kevin B. McGrattan, Glenn P. Forney, William L. Grosshandler, Cary Presser, L Melton
A series of experimental measurements were conducted and simple models were developed in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame stability in engine nacelle applications. The

Oxidation of Soot and Carbon Monoxide in Hydrocarbon Diffusion Flames

January 1, 1994
Author(s)
R. Puri, R J. Santoro, K C. Smyth
Quantitative OH concentrations and primary soot particle sizes have been determined in the soot oxidation regions of axisymmetric diffusion flames burning methane, methane/butane, and methane/1-butene in air at atmospheric pressure. The total carbon flow

Cybersecurity Framework Manufacturing Profile

September 8, 2017
Author(s)
Keith A. Stouffer, Timothy A. Zimmerman, CheeYee Tang, Joshua Lubell, Jeffrey A. Cichonski, John McCarthy
[Superseded by NISTIR 8183 (September 2017, Includes updates as of May 20, 2019)]This document provides the Cybersecurity Framework (CSF) implementation details developed for the manufacturing environment. The "Manufacturing Profile" of the Cybersecurity
