Analysis of Variability in the Design of Wood Products Under Imprecision

July 1, 1997
Author(s)
Ronald Giachetti, R Young
The design and analysis of many products is performed with imprecisely known parameters, relationships, and environmental conditions. This is especially true for wood products which exhibit greater variability than most materials. Fuzzy set theory applied

Atomic Collisions in Ultracold Atomic Gases

July 1, 1997
Author(s)
Paul S. Julienne, Kevin Jones, Paul D. Lett, William D. Phillips, Eite Tiesinga, U Volz, Carl J. Williams
Cold collisions between trapped atoms are very important in the context of Bose-Einstein condensation. The meaning of the scattering length, and its determination through the precision measurements of photoassociation spectroscopy, are described. This is

Biological Macromolecule Crystallization Database

July 1, 1997
Author(s)
G L. Gilliland
The NIST/CARB Biological Macromolecule Crystallization Database (BMCD) includes crystal and crystallization data on all forms of biological macromolecules that have produced crystals suitable forX-ray diffraction studies. The data include information on

Conference Report: Workshop on Advanced Methods and Models for Appearance of Coatings and Coated Objects, Gaithersburg, MD, May 20, 1996

July 1, 1997
Author(s)
M E. McKnight, J Martin, Michael Galler, Fern Y. Hunt, R Lipman, Theodore V. Vorburger, A Thompson
To help NIST researchers better understand industry''s needs, four NIST laboratories held a Workshop on Advanced Methods and Models for Appearance of Coatings and Coated Objects on May 20, 1996. The four NIST laboratories are Building and Fire Research

Dimensional Metrology at the Nanometer Level: Combined SEM and PPM

July 1, 1997
Author(s)
Michael T. Postek, H Ho, L Harrison
The National Institute of Standards and Technology (NIST) is currently exploring the potentials afforded by the incorporation of a commercial proximal probe microscope (PPM) operating in the scanning tunneling or atomic force mode into a high resolution

Growth morphologies of heteroepitaxial rutile films on sapphire substrates

July 1, 1997
Author(s)
P. A. Morris-Hotsenpiller, Alexana Roshko, J. B. Lowekamp, G. S. Rohrer
The growth morphologies of (1 0 0), (1 0 1) and (0 0 1) rutile films grown on sapphire substrates by the ion-beam sputter deposition technique have been examined as a function of film/substrate orientation, film thickness, substrate surface preparation

Managing Tcl's Namespaces Collaboratively

July 1, 1997
Author(s)
Don E. Libes
The NIST Identifier Collaboration Service (NICS) is a proposed service to encourage collaboration among researchers and developers when choosing identifiers, far in advance of when it might ordinarily occur. This would support and enhance standards

Measurement of Heat Conduction Through Stacked Screens

July 1, 1997
Author(s)
T Kuriyama, F Kuriyama, Michael A. Lewis, Ray Radebaugh
This paper describes the experimental apparatus for the measurement of heat conduction through stacked screens as well as some experimental results taken with the apparatus. Screens are stacked in a fiberglass-epoxy cylinder, which is 24.4 mm in diameter

Microstuctural Characterization of Hardened Steel by Nondestructive Methods

July 1, 1997
Author(s)
P T. Purtscher, B Igarashi, Donna C. Hurley, K W. Hollman
This paper describes the application of a variety of methods to the nondesctructive characterization (NDC) of microstructure in hardened steels. The measurements include ultrasonic velocity, nonlinear ultrasonics, resonant ultrasonic spectroscopy (RUS)
