The GOES Time Code Service, 1974 - 2004: A Retrospective

February 27, 2005
Author(s)
Michael A. Lombardi, D. W. Hanson
After nearly 30 years of continuous operation, NIST ended its Geostationary Operational Environmental Satellites (GOES) time code service at 0 hours, 0 minutes Coordinated Universal Time (UTC) on January 1, 2005. This event marked the end of an important

Traceable Pico-Meter Level Step Height Metrology

December 1, 2004
Author(s)
Ndubuisi G. Orji, Ronald G. Dixson, Joseph Fu, Theodore V. Vorburger
The atomic force microscope (AFM) increasingly being used as a metrology tool in the semiconductor industry where the features measured are at the nanometer level and continue to decrease. Usually the height sensors of the AFM are calibrated using step

Isotopic Metrology of Carbon Dioxide. I. Interlaboratory Comparison and Empirical Modeling of Inlet Equilibration Time, Inlet Pressure, and Ion Source Conductance

June 1, 2003
Author(s)
R M. Verkouteren, C E. Allison, S A. Studley, K J. Leckrone
We report a pilot study of high-precision differential isotopic ratio measurements made on replicate samples of pure carbon dioxide using three instruments of identical manufacture. Measurement protocols were designed to explore the effects of sample size

Energy Consumption Measurements Using AHAM HRF-1 and ISO 8561

March 10, 2003
Author(s)
David A. Yashar
This investigation compares the energy consumption ratings obtained for refrigerators using the Association of Home Appliance Manufacturers (AHAM) HRF-1 test procedure, as adopted by the United States Department of Energy (DOE), and the International

Refrigeration Methods for Superconductors

December 1, 2002
Author(s)
Ray Radebaugh
This chapter reviews various methods commonly used for achieving the cryogenic temperatures required of superconducting materials. The problems associated with cryogenic refrigerators (cryocoolers), such as poor reliability, low efficiency, electromagnetic

Review of Residential Sprinkler Systems: Research and Standards

December 1, 2002
Author(s)
Daniel M. Madrzykowski, R P. Fleming
Automatic sprinkler systems have been successfully used to protect industrial and commercial buildings and their occupants for more than 100 years. Historically, the place which has offered the least amount of fire protection to occupants, was and still is

Triggered Image Capture for High Speed Display Characterization

January 1, 2002
Author(s)
John W. Roberts
¿¿¿Precision display measurements often involve the integration of light measurements over many frames. Newer display technologies with high speed light modulators such as micromirrors are able to make sophisticated use of temporal modulation. This may

The Stability of Nb/Nb 5 Si 3 Microlaminates at High Temperatures

September 1, 2001
Author(s)
D van Heerden, A J. Gavens, P R. Subramanian, Timothy J. Foecke, Timothy P. Weihs
The chemical, phase and microstructural stability of Nb/Nb 5Si 3 microlaminates was investigated at temperatures ranging from 1200 C to 1600 C. The microlamintes were vapor deposited at room temperature and subsequently annealed at 1200 C to crystallize

High Temperature Lead-free Solder for Microelectronics

June 1, 2001
Author(s)
Frank W. Gayle, G Becka, J Badgett, G Whitten, TG Y. Pan, A Grusd, B B. Bauer, R Lathrop, J Slattery, I Anderson, J Foley, D Napp, J D. Mather, C Olson
This paper reports the result of a four-year industrial consortium effort to develop Pb-free solders for high temperature applications (up to 160 degrees c). Work included preliminary evaluation of 32 Sn-based alloys, a screening of the thermomechanical

Heat Flux Transducer Calibration: Summary of the 2nd Workshop

November 1, 1999
Author(s)
William L. Grosshandler
The second workshop on heat flux gauge calibration was organized to share the results of an effort to expand competence at NIST, and to examine the recommendations made at a previous workshop on heat flux gauge calibration. Over 40 attendees were drawn

Cyanate Ester Clay Nanocomposites: Synthesis and Flammability Studies

May 23, 1999
Author(s)
Jeffrey W. Gilman, Richard H. Harris Jr., Douglas Hunter
New goals outlined by the U. S. Federal Aviation Administration (FAA) Advanced Fire-Safe Aircraft Materials Research Program enumerate an order-of-magnitude improvement in aircraft cabin-material fire safety. In the pursuit of improved approaches to the

Advancing forensic SNP typing: Insights from an interlaboratory study of the FORCE panel
