Author(s)
Jun-Feng Song, Eric P. Whitenton, David R. Kelley, Robert A. Clary, L Ma, Susan M. Ballou, M Ols
The National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) 2460/2461 standard bullets and casings project will provide support to firearms examiners and to the National Integrated Ballistics Information Network (NIBIN) in

A PDA Security Policy Enforcement Tool

July 9, 2002
Author(s)
Athanasios T. Karygiannis, Wayne Jansen, Serban I. Gavrila, Vlad Korolev
This paper describes a proof-of-concept implementation of a Personal Digital Assistant (PDA) Security Policy Enforcement Tool developed by NIST. This tool can assist enterprise security administrators in setting, updating, monitoring, and enforcing group

A Bose-Einstein Condensate in an Optical Lattice

July 1, 2002
Author(s)
J Denschlag, J E. Simsarian, H Heffner, C R. McKenzie, A Browaeys, D Cho, Kristian Helmerson, S L. Rolston, William D. Phillips
We have performed a number of experiments with a Bose-Einstein condensate (BEC) in a one dimensional optical lattice. Making use of the small momentum spread of a BEC and standard atom optics techniques a high level of coherent control over an artifical

A Facility for Nanoscience Research: An Overview

July 1, 2002
Author(s)
Joseph A. Stroscio, E Hudson, Steven R. Blankenship, Robert Celotta, Aaron P. Fein
We describe the development of an experimental system, consisting of a low temperature scanning tunneling microscope coupled to UHV tip and sample preparation chambers, with the goal of providing new measurement capabilities for the study of quantum and

A Monolithic Implementation of Interface Circuitry for CMOS Compatible Gas-Sensor System

July 1, 2002
Author(s)
Muhammad Afridi, John S. Suehle, Mona E. Zaghloul, David W. Berning, Allen R. Hefner Jr., Stephen Semancik, Richard E. Cavicchi
A monolithic CMOS micro-gas-sensor system, designed and fabricated in a standard CMOS process, is described. The gas-sensor system incorporates an array of four microhotplate-based gas-sensing structures. The system utilizes a thin film of tin-oxide (SnO 2

A New Analytical Model of Shared Backup Path Provisioning in GMPLS Networks

July 1, 2002
Author(s)
Sanghun Lee, David W. Griffith, N-O Song
As GMPLS and its supporting set of protocols develop into aviable control plane for optical networks, an important function that they will need to support will be the protection and restoration function that has been a major feature of legacy optical

A New Classification of Information: A Step on the Road to Interoperability

July 1, 2002
Author(s)
Albert T. Jones, Larry H. Reeker
Complex systems, such as manufacturing supply chains, are often modeled as a collection of interacting components with information flows between them. These components are frequently responsible for making a wide range of decisions that are implemented

A Priority Agenda for Energy-Related Indoor Environmental Quality Research

July 1, 2002
Author(s)
W J. Fisk, G Brager, M Brook, H Burge, J Cole, J Cummings, H Levin, V Loftness, T Logee, M J. Mendell, Andrew K. Persily, S Taylor, J Zhang
A multidisciplinary team of IEQ and energy researchers is working together to define a program of priority energy-related IEQ research. This paper describes the methods employed, ten high priority broad research and development (R&D) goals, and 34 high

Ab Initio Calculation of KLV Auger Spectra in Si

July 1, 2002
Author(s)
E K. Chang, Eric L. Shirley
We present an ab initio Green's function formalizm for predicting CCV Auger spectra for solids. The formalizm takes into account core-hole screening final-state interaction effects, and angular-momentum dependence. it is applied to calculate the KLV Auger

Advanced Numerical Methods for Polymer Mass Spectral Data Analysis

July 1, 2002
Author(s)
William E. Wallace, Charles M. Guttman, Anthony J. Kearsley, Javier Bernal
A mathematical algorithm is presented that accurately locates and calculates the area beneath peaks using only reproducible mathematical operations and a single user-selected sensitivity parameter.

An Empirical Approach to Determining Rockwell Hardness Measurement Uncertainty

July 1, 2002
Author(s)
Samuel R. Low III, Walter S. Liggett Jr
Characteristics of the empirically developed Rockwell hardness test make it difficult to determine measurement uncertainty using methods traditionally applied to other metrological measurements. An empirical approach to determining Rockwell hardness

An XML Namespace for IUPAC

July 1, 2002
Author(s)
Stephen E. Stein
The author presented two talks at the IUPAC/CAS conference of Chemical identifiers and XML in Chemistry, on July 1, 2002 in Columbus Ohio. He will be sending PowerPoint presentations of these talks, both concerning on-going projects at NIST, to IUPAC for

Anatomy of Spin-Transfer Torque

July 1, 2002
Author(s)
Mark D. Stiles, A Zangwill
Spin-transfer torques occur in magnetic heterostructures because the transverse component of a spin current that flows from a non-magnet into a ferromagnet is absorbed at the interface. We demonstrate this fact explicitly using free electron models and

Autonomous Mobility for the Demo III Experimental Unmanned Vehicles

July 1, 2002
Author(s)
Alberto Lacaze, Karl Murphy, M DelGiono
This paper will describe the autonomous mobility controller used under the U.S. Army sponsored Demo III eXperimental Unmanned Vehicle (XUV) project. The controller is designed for avoiding obstacles and traversing highly unstructured outdoor environments

Bridging the Gap Between Structure and Properties in Nano-Particle Filled Polymers

July 1, 2002
Author(s)
Erik K. Hobbie, Francis W. Starr, Jack F. Douglas, Charles C. Han
On May 29-30, 2002, a workshop on polymer nanocomposites was held at NIST in Gaithersburg, Maryland. The workshop was entitled Bridging the Gap Between Structure and Properties in Nanoparticle-Filled Polymers and focused primarily on the interrelation

Chemical Ionization of Saturated Hydrocarbons Using Organometallic Ion Chemistry

July 1, 2002
Author(s)
H M. Byrd, Charles M. Guttman, D P. Ridge
Introduction: The potential for quick and direct measurement of chemical composition, absolute molecular mass (MM), MM distribution of linear and branched saturated polyolefins makes mass spectrometry especially attractive to the polymer industry. However
