The NIST Data Gateway is a Web portal that provides easy access to NIST scientific and technical data, which cover a broad range of substances and properties from many different scientific disciplines. Users can search for specific keywords, properties

NIST RM (Reference Material) 8240/8250 Standard Bullets and Casings Project

September 1, 2002
Author(s)
Jun-Feng Song, Theodore V. Vorburger, Susan M. Ballou, M Ols
The NIST RM (Reference Material) 8240/8250 Standard Bullets and Casings Project aims to support the National Integrated Ballistics Information Network (NIBIN) in the U.S. Two prototype standard bullets were developed in 1998 with all six lands manufactured

Noise Temperature for Nb DHEB Mixer Receiver for Far-Infrared Spectroscopy

September 1, 2002
Author(s)
Eyal Gerecht, Carl D. Reintsema, Erich N. Grossman, A. L. Betz, R. T. Boreiko
We are reporting a noise temperature measured on a diffusion-cooled hot electron bolometeric (DHEB) mixer designed for a heterodyne focal plane array to study lines with frequencies of 2 THz and above. Our fabrication process utilizes selective ion milling

Normal Mode Mixing and Ferromagnetic Resonance Linewidth

September 1, 2002
Author(s)
A B. Kunz, Robert D. McMichael
This spin wave modes for a uniform film are perturbed by the inclusion of inhomogeneities into the system. The resulting perturbed Hamiltonianis diagonalized to create a new set of spin waves modes. The effect of the strength of the perturbations is

Optical Reflectance of Metallic Coatings: Effect of Aluminum Flake Orientation

September 1, 2002
Author(s)
Li Piin Sung, Maria E. Nadal, M E. McKnight, Egon Marx, B Laurenti
The orientation of platelet-like pigments in coatings is affected by the processing conditions resulting in appearance variations of the final product. A set of aluminum-flake pigmented coatings having different flake orientations was pre-pared using

Passively Mode-Locked Waveguide Laser with Low Residual Jitter

September 1, 2002
Author(s)
John B. Schlager, Berton Callicoatt, Richard Mirin, Norman Sanford
Picosecond pulses at 1.53 υm with low residual jitter are generated from a passively mode-locked erbium/ytterbium co-doped planar waveguide laser in an extended cavity configuration. The round-trip frequency of the laser cavity is actively referenced to

Polarized Light Scattering by Dielectric and Metallic Spheres on Silicon Wafers

September 1, 2002
Author(s)
Jae H. Kim, S H. Ehrman, George W. Mulholland, Thomas Germer
The Polarization and intensity of light scattered by monodisperse polystyrene latex and copper spheres, with diameters ranging from 92 to 218 nm, deposited on silicon substrates were measured with 442-, 532-, and 633-nm light. The results are compared with

Polarized Ultraviolet Raman Spectroscopy of B-Si 3 N 4

September 1, 2002
Author(s)
R Vogelgesang, M Grimsditch, Jay S. Wallace
We have studied single crystals of Β-Si 3N 4 with polarization-resolved Raman spectroscopy in order to unambiguously obtain the symmetry character of zone center optical phonon modes. By applying ultraviolet excitation radiation, approaching resonance

Prediction of Cement Physical Properties by Virtual Testing

September 1, 2002
Author(s)
Dale P. Bentz, C Haecker, X Feng, Paul E. Stutzman
Assuring the quality of the massive quantities of cement produced worldwide each year is a daunting task. Currently, the cement industry performs extensive physical testing to assess the quality of their product, resulting in large costs for both materials

Preisach-Arrhenius Model for Thermal Aftereffect

September 1, 2002
Author(s)
Edward Della Torre, Lawrence H. Bennett, R A. Fry, O A. Ducal
tereffect, that is, decay of magnetization with time at a fixed holding field, is often linear in log-time for a limited time window. The slope at the holding field that maximizes the decay rate, normally near the field that maximizes the irreversible

Proceedings of the Biometric Consortium Conference|| September 23-25, 2002

September 1, 2002
Author(s)
Fernando L. Podio, J S. Dunn
¿¿¿The Biometric Consortium Conference examines rapid advances in biometric technologies and applications and explores new developments in the areas of metrology, assurance, and standards. The Conference proceedings include presentations in a series of

Prototype Implementation of an Automated Structural Steel Tracking System

September 1, 2002
Author(s)
K M. Furlani, D T. Latimer, David E. Gilsinn, Alan M. Lytle
This paper discusses the prototype implementation of a system developed by researchers at the National Institute of Standards and Technology (NIST) for the transfer of real-time on-site metrology and metrology-based data for tracking steel frame

Reconstructing Images of Bar Codes for Construction Site Object Recognition

September 1, 2002
Author(s)
David E. Gilsinn, Geraldine S. Cheok, Dianne M. O'Leary
This paper discusses a general approach to reconstructing ground truth intensity images of bar codes that have been distorted by LADARoptics. The first part of this paper describes the experimental data collection of several bar code images along with

Author(s)
Alan M. Lytle, Kamel S. Saidi, William C. Stone, John L. Gross
The Building and Fire Research Laboratory of the National Institute of Standards and Technology, in cooperation with the American Institute of Steel Construction, sponsored a workshop on automated steel construction. The purpose of the workshop was to

Review of Traceable Temperatures and Temperature Measurement

September 1, 2002
Author(s)
Dean C. Ripple
Traceable Temperatures outlines the most common methods of measuring temperature and teaches the reader practical skills in assuring that those measurements are made with confidence at a known level of uncertainty. For a beginning user of thermometers or
