Improving the Accuracy of Particle Analysis

July 1, 2000
Author(s)
John A. Small, J R. Michael, Dale E. Newbury
Historically the procedures for the quantitative X-ray analysis of particles in the electron probe have been similar to the methods used for bulk electron probe samples.The main difference was that corrections had to be made to the experimental k-ratios or

Information Technology for Engineering and Manufacturing

July 1, 2000
Author(s)
James E. Fowler, Mark G. Carlisle
This paper summarizes material presented at Information Technology for Engineering & Manufacturing, a conference organized by NIST's Systems Integration for Manufacturing Applications (SIMA) program office to examine problems facing manufacturers as they

Integration of Manufacturing Simulations Using High Level Architecture (HLA)

July 1, 2000
Author(s)
Charles R. McLean, Swee K. Leong, Frank H. Riddick
This paper presents an overview of a neutral reference architecture for integrating distributed manufacturing simulation systems with each other, with other manufacturing software applications, and with manufacturing data repositories. Other manufacturing

Internet Commerce for Manufacturing Data Staging

July 1, 2000
Author(s)
C Parks, Jim G. Nell
This paper describes the process-flow model as proposed for use in the Internet Commerce for manufacturing (ICM), a project of the National Advanced Manufacturing Test Bed program. This model will be used to identify those internet-facilitated transactions

Low-Frequency Impedance Calibrations at NIST

July 1, 2000
Author(s)
Andrew D. Koffman, Yui-May Chang
This paper presents an overview of the low-frequency impedance measurement services offered through the Impedance Calibration Laboratory (ICL) at the National Institute of Standards and Technology (NIST). Emphasis will be given to recent improvements as

Management Data Specification for Supply Chain Integration

July 1, 2000
Author(s)
Yung-Tsun Lee, Shigeki Umeda
This document specifies a framework of communication data in a supply chain system, which is viewed as a virtual enterprise. First presented is a requirement analysis to identify the information necessary to represent the communication for the produciton

Manufacturing Feature Recognition from Solid Models: A Status Report

July 1, 2000
Author(s)
Jung-Hyun Han, Mike Pratt, William Regli
Solid modeling refers to techniques for unambiguous representations of three-dimensional objects. Feature recognition is a sub-discipline focusing on the design and implementation of algorithms for detecting manufacturing information such as holes, slots

Manufacturing Planning and Execution Objects Foundation Interfaces

July 1, 2000
Author(s)
Shaw C. Feng
Process planning and manufacturing execution software systems provide two major functions in a product development cycle. Industries require the systems that support these two functions to be able to interoperate with other related manufacturing software

MatML: An XML for Standardizing Web-Based Materials Property Data

July 1, 2000
Author(s)
E F. Begley, C P. Sturrock
Hypertext Markup Language (HTML) may be current lingua franca of the World Wide Web, but it is poorly suited for exchanging multidimensional data for any kind, including materials property data. XML, or eXtensible Markup Language, provides for the

Measurements in Support of Research Accomplishments

July 1, 2000
Author(s)
D S. Pallett, John S. Garofolo, Jonathan G. Fiscus
This paper reviews the role provided by the National Institute of Standards and Technology (NIST) in the development of measurements in support of broadcast news-based technologies. The focus of these measurements was initially on specifying the word error

Michelson Interferometry With 10 PM Accuracy

July 1, 2000
Author(s)
John R. Lawall, Ernest G. Kessler
We demonstrate a new heterodyne Michelson interferometer design for displacement measurements capable of fringe interpolation accuracy of one part in 36,000. Key to this level of accuracy are the use of two accousto-opic modulators for heterodyne frequency
