Uncertainty Intervals for Polarized Beam Scattering Asymmetry Statistics

July 1, 1993
Author(s)
Kevin Coakley, Jabez McClelland, Michael H. Kelley, Robert Celotta
In many scattering experiments, the quantity of most direct physical interest is a measure of the difference between two closely related scattering signals, each generated by a Poisson scattering process. This difference is often expressed in terms of an

The Use of Vision and Touch Sensors for Dimensional Inspection Tasks

June 2, 1993
Author(s)
M Nashman
The purpose of dimensional inspection is to verify the geometry of a manufactured part. A machined part is either accepted or rejected based upon the sensed errors between the object and its specified geometry as defined in a CAD (Computer Aided Design)

A Tribometer for Measurements in Hostile Environments

June 1, 1993
Author(s)
Andrew Slifka, J Chaudhuri, R Compos, James D. Siegwarth
A tribometer at the National Institute of Standards and Technology in Boulder, Colorado is used to measure the coefficient of friction and the wear rate for various specimens in a controlled atmosphere of oxygen or non-corrosive gas. The wide range of

AP Validation Workshop

June 1, 1993
Author(s)
Mary Mitchell
During the course of the ISO/IPO meeting held in Seattle, Washington, in April of 1992, a one-day workshop was held on AP validation requirements and procedures. Included in this workshop were representatives from all approved AP projects and planning

Computer-Aided Manufacturing System Engineering

June 1, 1993
Author(s)
Charles R. McLean
A new type of computer-aided engineering environment is envisioned which will improve the productivity of manufacturing/industrial engineers. This environment would be used by engineers to design and implement future manufacturing systems and subsystems

Dimensional Inspection Planning Based on STEP and DMIS

June 1, 1993
Author(s)
Shaw C. Feng
An international standard on product data representation and exchange for dimensional inspection planning is being developed. This paper provides a review of fundamental technology enabling the standard development and describes the current status of an

Fire Evacuation by Elevators

June 1, 1993
Author(s)
J H. Klote, Scott Deal, E. A. Donoghue, Bernard M. Levin, N Groner
There is a rising concern for the safety of persons from fire who cannot travel building emergency exit routes in the same manner or as quickly as expected of able persons. One proposed solution for providing safety for these people is the use of elevators
