Multimode Fiber Transceiver Launch Distribution: Results of an Industry Round Robin

September 1, 1999
Author(s)
John B. Schlager, M. J. Hackert, M. Pepeljugoski, Mike Murphy, R. Neumann, J. Gwinn
An industry round robin conducted by the Telecommunications Industry Association FO-2.2 Task Group on the Modal Dependence of Bandwidth demonstrates good inter-laboratory agreement for measurements of transceiver encircled flux.

NIST Response to MES Request for Information

September 1, 1999
Author(s)
Edward J. Barkmeyer Jr., Peter O. Denno, Shaw C. Feng, Evan K. Wallace, Albert T. Jones
This is a response from the National Institute of Standards (NIST) to OMG's Request for Information concerning the Manufacturing Execution System (MES) area [RFI3]. There has been quite a bit of previous work at NIST, related to this RFI which influenced

Non-Intrusive Scanning Technology for Construction Assessment

September 1, 1999
Author(s)
Geraldine S. Cheok, William C. Stone
Work at the National Institute of Standards and Technology on laser radar imaging of a construction site is described. The objective of the research is to make measurements required in a construction project quicker and cheaper than current practice and to

Non-Self-Similar Modes of Vibration of a Bose-Einstein Condensate

September 1, 1999
Author(s)
M Brewczyk, Charles W. Clark, M Lewenstein, K Rzazewski
A hydrodynamical version of the time-dependent Gross-Pitaevskii equation is used to describe driven vibrations of a Bose-Einstein condensate of 87Rb atoms in a magnetic trap. If the trap frequency is suddenly decreased, and later is suddenly returned to

Object Retrieval and Access Management in Electronic Commerce

September 1, 1999
Author(s)
S A. Wakid, John Barkley, Mark Skall
Electronic commerce over the Internet is now tens of billions of dollars per year and growing. This article describes how objects used in EC can be located and protected from unauthorized access. It discusses the three kinds of EC: customer interactions

Onset of Fermi Degeneracy in a Trapped Atomic Gas

September 1, 1999
Author(s)
B. L. DeMarco, Deborah S. Jin
An evaporative cooling strategy that uses a two-component Fermi gas was employed to cool a magnetically trapped gas of 7 x 10 5 40K atoms to 0.5 of the Fermi temperature T f. In this temperature regime, where the state occupation at the lowest energies has

OOMMF User's Guide, Version 1.0

September 1, 1999
Author(s)
Michael J. Donahue
This manual describes OOMMF (Object Oriented Micromagnetic Framework), a public domain micromagnetics program developed at NIST. The program is designed to be portable, flexible, and extensible, with a user-friendly graphical interface. The code is written

Photometry The CIE V(l) Function and What Can Be Learned from Photometry

September 1, 1999
Author(s)
Yoshihiro Ohno, E A. Thompson
The V(l) function, used in photometry, is an average action spectrum for the visual response of the human eye, and the matching of the spectral responsivity of photometers to V(l) is the most important criterion of photometers. Techniques have been

Polarization Distribution in Ceramic-Polymer Nanocomposites

September 1, 1999
Author(s)
P Bloss, A S. DeReggi, H J. Glasel, E Hartmann, D Hirsch, H Schafer
We report pyroelectric responsivity versus depth profiles in nanocomposites of powdered barium titanate and tripropylene glycol diacrylate obtained by using the thermal pulse (TP) method. The ceramic nanopowder (mean particle size 270 nm) was prepared by

Radiometric Measurement Comparisons Using Transfer Radiometers in Support of the Calibration of NASA's Earth Observing System (EOS) Sensors

September 1, 1999
Author(s)
James J. Butler, B. Carol Johnson, Steven W. Brown, Howard Yoon, R Barnes, B L. Markham, S F. Biggar, E F. Zalewski, P R. Spyak, J W. Cooper, F Sakuma
EOS satellite instruments operating in the visible through the shortwave infrared wavelength regions (from 0.4 um to 2.5 um) are calibrated prior to flight for radiance using integrating spheres at a number of instrument builder facilities. The

Spectroscopic Ellipsometry of Ta 2 0 5 On Si, in Ultrathin SiO 2 and High-K Materials for ULSI Gate Dielectrics, edited by H. R. Huff, C. A. Richter, M. L. Green, G. Lucovsky, and T. Hattori

September 1, 1999
Author(s)
Curt A. Richter, Nhan Van Nguyen, G A. Alers
In this paper, we present the results of spectroscopic ellipsometry (SE) studies of Ta 20 5 films on Si. Based on these results, we have experimentally determined an effective method for analyzing SE measurements of Ta 20 5. A set of CVD-grown Ta 20 5

Standards-Based Software Testing in a Net-Centric World

September 1, 1999
Author(s)
KC Morris, David Flater
Automation for product development and manufacturing is changing to take advantage of the recent expansion of the Internet and the computing technologies supporting it. These processes are becoming more software independent, and the software used is

Structured Markup on the Web: A Tale of Two Sites

September 1, 1999
Author(s)
Joshua Lubell
Business and organizations are increasingly finding that HTML (Hyper-Text Markup Language)offers no help whatsoever in managing the information on their web sites. SGML (Standard Generalized Markup Language) provides the flexibility and reuse lacking in
