Users' Guide for Hand-Held and Walk-Through Metal Detectors

January 1, 2001
Author(s)
A G. Lieberman, Kathleen M. Higgins, Nicholas Paulter
The guide provides the law enforcement and corrections (LEC) community with information concerning the theory and limits of operation of hand-held and walk-through metal weapon detectors. This guide is also intended to supplement National Institute of

Using Intelligent Agents to Assess Pervasive Computing Technologies

January 1, 2001
Author(s)
L P. Ciarletta, Alden A. Dima, V P. Iordanov
Pervasive Computing (a.k.a. Ubiquitous or Ambient Computing) is a new field of computer science generally considered to lie at the intersection of desktop computing, networking, and embedded systems. Related to pervasive computing are Intelligent

Using Self-Assembled Monolayer Technology to Probe the Fiber-Matrix Interface

January 1, 2001
Author(s)
Gale A. Holmes, E Feresenbet, D T. Raghavan
hesion at the fiber matrix interface of composite specimens is often ascribed to the following factors (Sharpe and Drzal): (1) mechanical interlocking, (2) physicochemical interactions, (3) chemical bonding, and (4) mechanical deformation of the fiber

Visible Fluoride Fiber Lasers

January 1, 2001
Author(s)
David S. Funk, J. G. Eden
The advent of low-loss fluoride fibers has led to the demonstration of numerous room-temperature lasers based on rare-earth transitions at wavelengths ranging from 0.38 to 3.45 υm. Fluoride fiber lasers are of interest because they provide a means of

Wavelength References for Wavelength Division Multiplexing

January 1, 2001
Author(s)
Sarah L. Gilbert, Tasshi Dennis, William C. Swann
We describe NIST research on wavelength standards for optical fiber communications. We have developed transfer standrds that can be used to calibrate instruments in the 1510-1560 nm region and a investigating references for other regions.

Wavelength standards for optical communications

January 1, 2001
Author(s)
Sarah L. Gilbert, William C. Swann, Tasshi Dennis
We review wavelength accuracy and calibration issues for wavelength division multiplexed (WDM) optical fiber communication and describe our work on wavelength calibration references. We have developed wavelength references for National Institute of
