Process Specification Language: An Analysis of Existing Representations

May 1, 1998
Author(s)
Amy Knutilla, Craig I. Schlenoff, Steven R. Ray, Stephen T. Polyak, Austin Tate, S C. Cheah, Richard C. Anderson
The goal of the National Institute of Standards and Technology (NIST) Process Specification Language (PSL) project is to investigate and arrive at a neutral, unifying representation of process information to enable sharing of process data among

Sample-Angle Feedback for Diffraction Anomalous Fine-Structure Spectroscopy

May 1, 1998
Author(s)
J O. Cross, W Elam, V G. Harris, J P. Kirkland, Charles E. Bouldin, L B. Sorensen
Diffraction anomalous fine-structure (DAFS) experiments measure Bragg peak intensities as continuous functions of photon energy near a core-level excitation. Measuring the integrated intensity at each energy makes the experiments prohibitively slow

Small-Area Black Luminance Measurements on White Screen Using Replica Masks

May 1, 1998
Author(s)
Paul A. Boynton, Edward F. Kelley
Luminance measurements of small areas of black pixels on white-screen backgrounds are often used as metrics in display measurements, such as character-stroke contrasts or deep modulation transfer functions. Serious errors may be made in measurements and

Trapped Ions, Entanglement, and Quantum Computing

May 1, 1998
Author(s)
C J. Myatt, B E. King, D Kielpinski, Dietrich Leibfried, C S. Turchette, Chris S. Wood, Wayne M. Itano, C Monroe, David J. Wineland
A miniature, elliptical ring rf (Paul) ion trap has been used in recent experiments toward realizing a quantum computer in a trapped ion system. With the combination fo small spatial dimensions and high rf drive potentials, around 500 V amplitude, we have

Ultrasonic Characterization in Advanced Processing of Ceramic Powders

May 1, 1998
Author(s)
Vincent A. Hackley
A world wide web (www) site focussing on NIST efforts in ultrasonic applications development for ceramic processing in fluid-based systems. This site contains information related to facilities, instrumentation, research, and ultrasonic techniques in

Viewing Angle: A Matter of Perspective

May 1, 1998
Author(s)
T. G. Fiske, L. D. Silverstein, C. Penn, Edward F. Kelley
Setting viewing angle requirements and specifications for displays depends on how viewing angle is defined. There is significant confusion in the industry regarding the definition and use of horizontal and vertical viewing angle. Moreover, the relations

Monitoring Composites with Optical Fiber Sensor Systems

April 26, 1998
Author(s)
Richard~undefined~undefined~undefined~undefined~undefined Parnas, Joy Dunkers, R A. Neff
An inexpensive optical fiber has been interfaced with high-speed fluorescence and near infrared spectrometers to provide real-time monitoring of fast-reacting systems. Cure monitoring measurements were conducted in high volume fraction, glass reinforced

TREC-6 Interactive Track Report

April 24, 1998
Author(s)
Paul D. Over
This report is an introduction to the work of the TREK-6 Interactive Track with its goal of investigating interactive information retrieval by examining the process as well as the results.Twelve interactive information retrieval (IR) systems were run on a

A Federal Public Key Infrastructure With Multiple Digital Signature Algorithms

April 22, 1998
Author(s)
William E. Burr, William T. Polk
Several digital algorithms are coming into general use. A certificate containing a key for one algorithm can be signed with a different algorithm. This paper discusses the interoperability issues where different digital signature algorithms are used in one

NIST/NBS Fire Research and FRCA: 25 Years of Progress

April 16, 1998
Author(s)
Richard G. Gann
The National Bureau of Standards' Center for Fire Research and the Fire Retardant Chemicals Association were formed within a year of each other. The former has undergone major organizational changes, NBS having become NIST, and fire research now being part

The Surgeon's Assistant

April 14, 1998
Author(s)
K Gallagher, D Wallace, Frederick E. Boland Jr., D W. Binkley, James R. Lyle
The Surgeon's Assistant is a tool for the maintainers of ANSI C programs. Using the Surgeon's Assistant, a software maintainer (a surgeon) can isolate program components for change; assess the impact of contemplated changes on components that are to remain
