Switching Mechanism of Single Domain Particles in a Two-Dimensional Array

September 1, 1999
Author(s)
Martha Pardavi-Horvath, G Vertesy, B Keszei, Z Vertesy, Robert D. McMichael
The mechanism of switching of uniaxial, single domain, single crystalline epitaxial garnet particles on a 2D square array was investigated. The anisotropy field of the sample is 2 kOe, while the gaussian switching field distribution is 280 85 Oe. The

Diode Lasers in Length Metrology: Application to Absolute Distance Interferometry

January 1, 1999
Author(s)
Jack A. Stone Jr., Lowell P. Howard, Alois Stejskal
Diode lasers are becoming increasingly important in length metrology. In particular, the tunability of diode lasers makes them attractive for applications such as absolute distance interferometry (ADI). In this paper we describe the current status of our

The FERET Verification Testing Protocol for Face Recognition Algorithms

October 1, 1998
Author(s)
S A. Rizvi, P. Jonathon Phillips, H Moon
Two critical performance characterizations of biometric algorithms, including face recogntion, are identification and verification. In face recognition, FERET is the de facto standard evaluation methodology. Identification performance of face recognition

Production Systems Engineering: Requirements Analysis for Discrete-Event Simulation

June 1, 1998
Author(s)
Anna Bartolotta, Charles R. McLean, Yung-Tsun T. Lee, Albert W. Jones
This document describes the results of the requirement analysis phase for a neutral interface specification to discrete event simulation software. The interface specification should provide a neutral mechanism capable of describing input data to a discrete

Vibration of a Room-Sized Airspring-Supported Slab

APDE Demonstration System Architecture

August 1, 1993
Author(s)
Steve Clark, Allison Barnard Feeney
The National PDES Testbed project at NIST is focused on the development and implementation of the emerging international Standard for the Exchange of Product Model data (STEP). One sub-project within the Testbed is the effort to establish an Application

Frequency stabilization of a tunable erbium-doped fiber laser

January 1, 1991
Author(s)
Sarah L. Gilbert
A single-frequency Er-doped fiber laser that is tunable from 1.52 to 1.58 μm has been constructed. The laser linewidth was determined to be less than 1.6 MHz FWHM by observing the spectrum of the beat between the fiber laser and a 1.523-μm He-Ne laser. The

A note on flow rate and leak rate units

April 28, 1986
Author(s)
Charles D. Ehrlich
The confusion in the literature and in the laboratory surrounding the terminology and units of gas flow rates, particularly as applied to calibrated leak artifacts, has prompted this discussion of leak rate units. Special attention is paid to conflicting
