Combinatorial Peel Tests for the Characterization of Adhesion Behavior of Polymeric Films

February 1, 2005
Author(s)
R Song, Martin Chiang, A J. Crosby, Alamgir Karim, Eric J. Amis, Naomi Eidelman
The self-adhesion behavior of an optically smooth poly(methyl methacrylate) (PMMA) thin film (ca.. 100 nm) on different evaporated metal substrates has been investigated using a combinatorial method approach. In this investigation through high-throughput

Conformance Testing of the Government Smart Card

February 1, 2005
Author(s)
Barbara Guttman
The National Software Reference Library (NSRL) of the U.S. National Institute of Standards and Technology (NIST) collects software from various sources and publishes file profiles computed from this software (such as MD5 and SHA-1 hashes) as a Reference

Conformance Testing of the Government Smart Card

February 1, 2005
Author(s)
Elizabeth N. Fong
A conformance Test suite helps to ensure consistency between a specification and the behavior of a product. This paper presents the conformance testing methodology for the Government Smart Card Interoperability Specification. It starts with some basic

Effect of Image Size and Compression on One-to-One Fingerprint Matching

February 1, 2005
Author(s)
Craig I. Watson, Charles L. Wilson
NIST has conducted testing of one-to-one fingerprint matching systems to evaluate the effect of image size and compression on the accuracy of the one-to-one matching process. Images from three live-scan fingerprint scanners collected by the Departments of

General Purpose Calculator for Outdoor Propagation Loss

February 1, 2005
Author(s)
Leonard E. Miller, Camillo Gentile, D Kaspar
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Home Smoke Alarm Tests, Series 1, Report of Test FR 4016

February 1, 2005
Author(s)
Richard D. Peacock, Jason D. Averill, Richard W. Bukowski, Paul A. Reneke
This report documents the first test series in the program conducted to characterize the test environment. Data presented include CO, CO2, O2, smoke obscuration, and temperature. Additional measurement of smoke particle size and concentration, additional

Living With Uncertainty

February 1, 2005
Author(s)
Carl C. Miller, Yoshihiro Ohno
This article discusses measurement uncertainty. Definitions that are used in describing measurement uncertainty along with terms that should not be used. The significance and the procedure for calculating measurement uncertainty are presented.

Measurement of the Optical Extinction Coefficient of Combustion-Generated Aerosol

February 1, 2005
Author(s)
J F. Widmann, J X. Duchez, Joseph M. Conny, George W. Mulholland
This note describes mesurements of the optical extinction coefficient of carbonaceous aerosol produced during hydrocarbon combustion. Measurements of the mass specific extinction coefficient were obtained by laser extinction at 632 nm wavelength. The

Measuring the Permittivity and Permeability of Lossy Materials: Solids, Liquids, Metals, and negative-Index Materials

February 1, 2005
Author(s)
James R. Baker-Jarvis, Michael D. Janezic, Billy F. Riddle, Robert T. Johnk, Christopher L. Holloway, Richard G. Geyer, Chriss A. Grosvenor
The goal of this report is to be a comprehensive guide for researchers int he area of dielectric and magnetic measurements of lossy materials. The goal is to assemble the relevant information needed to perform and interpret dielectric measurements on lossy

Mixture Proportioning for Internal Curing

February 1, 2005
Author(s)
Pietro Lura, J W. Roberts
A methodology is presented for the mixture proportioning of ordinary Portland cement concretes to supply internal curing via the addition of saturated lightweight fine aggregates. The necessary internal curing water is calculated to balance the water
