Evaluation of Uncertainties in Fundamental Radiometric Measurements

October 1, 1998
Author(s)
Benjamin K. Tsai, Bettye C. Johnson
The uncertainty of measurements is critical in furthering the development of radiometric science and acquiring an increased understanding of its principles. Proper analysis of measurement uncertainties provides an indication of how well the measurements

Federal Register Document Image Database 25, Volume 1

October 1, 1998
Author(s)
Michael D. Garris, Stanley Janet, W Klein
A new, fully-automated process has been developed at NIST to derive ground truth for document images. The method involves matching optical character recognition (OCR) results from a page with typesetting files for an entire book. Public domain software

Ferromagnetic Resonance Studies of NiO-Coupled Thin Films of Ni 80 Fe 20

October 1, 1998
Author(s)
Robert D. McMichael, Mark D. Stiles, P J. Chen, William F. Egelhoff Jr.
This paper describes ferromagnetic resonance (FMR) and magnetoresistive measurements of thin magnetic films coupled to antiferromagnetic films. First, FMR results for films of Ni 80Fe 20 show that coupling to NiO produces the angular variation in the

Flammability Studies of Polymer Layered Silicate (Clay) Nanocomposites (NISTIR 6242)

October 1, 1998
Author(s)
Jeffrey W. Gilman, Takashi Kashiwagi, Marc R. Nyden, James E. Brown, C L. Jackson, S M. Lomakin, E P. Giannelis, E Manias
In the pursuit of improved approaches to fire retarding polymers a wide variety of concerns must be addressed, in addition to the flammability issues. First, the low cost of commodity polymers requires that the fire retardant (FR) approach also be of low

Gapped Arresters Revisited: A Solution to Cascade Coordination

October 1, 1998
Author(s)
A. Mansoor, Francois D. Martzloff, K. O. Phipps
This paper provides a brief perspective on how the coordination of cascaded surge-protective devices (SPDs) has become an issue. We propose an approach where the 'ancient' technology of gapped arresters may well be the answer to the dilemma of the

GenCAM Syntax Checker

October 1, 1998
Author(s)
Michael McLay
A conformance test module (CTM) for the GenCAM file format is being developed by National Institute of Standards and Technology to support an industry effort to develop the GenCAM standard. GenCAM is a product data exchange standard for information used in

High Frequency Limitations of the JEDEC 123 Guideline

October 1, 1998
Author(s)
Dylan F. Williams
Abstract: This paper assesses certain systematic high frequency measurement errors inherent in the procedures described in the JEDEC 123 Guideline for Measurement of Electronic Package Inductance and Capacitance Model Parameters.

Influence of Surface Silica on the Pyrolysis of Silicones (NISTIR 6242)

October 1, 1998
Author(s)
R R. Buch, John R. Shields, Takashi Kashiwagi, Thomas Cleary, Kenneth D. Steckler
Silicones encompass a wide variety of noval materials that find applications in virtually every major industry sector. The dominant polymer in the silicone industry is polydimethylsiloxane (PDMS). The combustion of long chain PDMS exhibits a low heat

Initial Results of the Bidirectional Reflectance Characterization Round-Robin in Support of EOS

October 1, 1998
Author(s)
Bettye C. Johnson, P Y. Barnes, Thomas R. O'Brian, James J. Butler, C J. Bruegge, S F. Biggar, P R. Spyak, M M. Pavlov
Laboratory measurements of the bidirecitonal reflectance distribution function (BRDF) of diffusely reflecting samples are required to support calibration in the National Aeronautics and Space Administration's (NASA's) Earth Observing System (EOS) program

InSb Working Standard Radiometers

October 1, 1998
Author(s)
George P. Eppeldauer, Alan L. Migdall, Leonard M. Hanssen
Standard quality InSb radiometers have been developed and characterized at the national Institute of Standards and Technology (NIST). The InSb radiometers will hold the recently realized spectral response scale of the NIST and will serve as working

Lessons Learned Developing Protocols for the Industrial Virtual Enterprise

October 1, 1998
Author(s)
Martin Hardwick, KC Morris, D L. Spooner, T Rando, Peter O. Denno
The National Industrial Infrastructure Protocols (NIIIP) Consortium formed in 1994 to develop protocols to allow for manufacturers and their suppliers to develop products across the internet. The protocols selected and developed by the NIIIP Consortium
