Colorimetric Accuracies and Concerns in Spectroradiometry of LEDs

October 2, 1999
Author(s)
C Jones, Yoshi Ohno
LEDs are narrow-band emission sources and present special problems in colorimetric characterization. Chromaticity space is mapped using Gaussian spectral models to represent narrow-band emission sources. The Gaussian maps show that the spectral regions are

Author(s)
Alden A. Dima, John P. Wack, S A. Wakid
… step towards validating security for components of computing devices. We will focus on software because, as we …

Design of a Digital Mathematical Library for Science, Technology and Education

February 26, 1999
Author(s)
Daniel W. Lozier, Bruce R. Miller, Bonita V. Saunders
The concept of a digital library is of proven worth because of its ability to provide dramatic capabilities that are impossible with traditional print media. We are interested in providing such capabilities for scientific, technical and educational users

A Molecular Dynamics Study of a Reversed-Phase Liquid Chromatography Model

February 1, 1999
Author(s)
J T. Slusher, Raymond D. Mountain
We describe a molecular dynamics simulation study of a model of the reverse-phase chromatographic system. The model consists of a slab of aqueous solvent sandwiched between two walls having attached C 8 hydrocarbon chains at a surface coverage of 5.09 mol

A Fast Pulse Oscilloscope Calibration System

October 1, 1998
Author(s)
J. P. Deyst, Nicholas Paulter, T. Daboczi, Gerard N. Stenbakken, T. M. Souders
A system is described for calibrating high-bandwidth oscilloscopes using pulse signals. The fast pulse oscilloscope calibration system (FPOCS) is to be used to determine the step response parameters for digitizing oscilloscopes having bandwidths of 20 GHz

Statistical Measure for the Sharpness of the SEM Image

July 1, 1997
Author(s)
Nien F. Zhang, Michael T. Postek, Robert D. Larrabee
Fully automated or semi-automated scanning electron microscopes (SEM) are now commonly used in semiconductor production and other forms of manufacturing. Testing and proving that the instrument is performing at a satisfactory level of sharpness is an

On Multiple Interpretations

May 1, 1997
Author(s)
Jung-Hyun Han
Literature of feature recognition, there has been a wall between feature recognition and process planning, Manufacturing knowledge which is typically used in process planning is rarely incorporated into feature recognition, and there is little

A Decision-based Framework for Exploring Assembly Configuration

April 1, 1995
Author(s)
Gerard Kim
In most engineering design processes, there are three major phases of design: functional, conceptual, and detailed design (Gui94). However, most current computer-aided design (CAD) systems are oriented toward support in detailed design (e.g. geometry

Pipe Flow Characteristics of Alternative Agents for Engine Nacelle Fire Protection

January 1, 1995
Author(s)
Thomas G. Cleary, Jiann C. Yang, William L. Grosshandler, Michelle King, C I. Boyer
As part of the U.S. Air Force, Army, Navy and FAA Halon Replacement Project at NIST, the pipe flow characteristics were investigated for three engine nacelle alternative candidates: HFC-227ea, HFC-125 and CF31. The flow regime in suppression system piping

Simulating the Effect of Flat Beamed Ceiling on Detector and Sprinkler Response

November 6, 1994
Author(s)
Glenn P. Forney, Richard W. Bukowski, William D. Davis
This paper documents a portion of the work performed during the first year of the International Fire Detection Research Project sponsored by the National Fire Protection Research Foundation (NFPRF). The first task was to confirm that fire sensor response

An Introduction to the NIST PDES Toolkit

June 1, 1990
Author(s)
Steve Clark
The PDES (Product Data Exchange using STEP) activity is the United States' effort in support of the Standard for the Exchange of Product Model Data (STEP), an emerging international standard for the interchange of product data between various vendors' CAD

Report of the NIST MEL Architecture Task Force

December 29, 2000
Author(s)
Harry A. Scott, John Evans, Steven R. Ray, E C. Teague, James S. Albus, Herbert T. Bandy, Edward J. Barkmeyer Jr., Neil Christopher, M A. Donmez, Hui-Min Huang, Albert W. Jones, Elena R. Messina, Jim G. Nell, Frederick M. Proctor, Evan K. Wallace
The NIST Manufacturing Engineering Laboratory undertook a series of internal working meetings to examine all of its architecture efforts. A survey of work was performed, and recommendations were identified. This document, initially compiled in 1999

Smart Home Device Loss of Support: Consumer Perspectives and Preferences

July 23, 2023
Author(s)
Julie Haney, Susanne M. Furman
Unsupported smart home devices can pose serious safety and security issues for consumers. However, unpatched and vulnerable devices may remain connected because consumers may not be alerted that their devices are no longer supported or do not understand

Design Patterns for Visualization-Based Tools in Sustainable Product Design

November 5, 2017
Author(s)
Deverajan Ramanujan, William Z. Bernstein, Karthik Ramani
Most design activities involve exploring and comparing similar existing designs. Thus, adopting an eco-conscious approach in the design exploration process can aid environmentally sustainable product design (SPD). A promising approach for supporting
