Engineering Aspects of the September 19, 1985 Mexico Earthquake (NBS BSS 165)

May 29, 1987
Author(s)
William C. Stone, Felix Y. Yokel, Mehmet Celebi, Thomas Hanks, Edgar V. Leyendecker
Following the September 19, 1985 Mexico earthquake, a team consisting of four engineers and one seismologist from the Naitonal Bureau of Standards (NBS)and the United States Geological Survey (USGS) was dispateched to Mexico City to provide technical

Finite-Element Analysis of Flexible Fixturing System

May 29, 1987
Author(s)
Jonathan W. Lee, L Haynes
A computer software has been developed for the analysis and design of fixtures. This software can lead the designer to the optimal design of the fixturing system which minimizes the total work done on the workpiece, the fixturing force, the deformation

Robot Sensor Language

May 14, 1987
Author(s)
S Leake
RSL (Robot Sensor Language) is a data-driven, semi-interpreted, hierarchical, user extensible, robot task description language. It provides four levels of task decomposition, with structures and syntax specialized for each level. The user can add commands

AMRF Process Planning System

May 1, 1987
Author(s)
Charles R. McLean, Peter Brown
As more intelligent automated control systems are introduced into discrete parts manufacturing facilities, it will become increasingly difficult to maintain the centralized process planning systems in use today. A new approach is required that will permit

Interface Concepts for Plug-Compatible Production Management Systems

May 1, 1987
Author(s)
Charles R. McLean
Currently, the integration of production management systems that have been built by different vendors is either costly and time-consuming or virtually impossible. If factory integration costs are to be reduced, it is essential that these systems be made

Scanning Electron Microscopy with Polarized Electrons

April 15, 1987
Author(s)
john unguris, G Hembree, Robert Celotta, Daniel T. Pierce
The recent joining of scanning electron microscopy and electron spin polarization analysis has greatly improved the ability to study magnetic microstructure. By measuring the spin polarization of secondary electrons, scanning electron microscopy with

A Cell Control Architecture for Flexible Manufacturing

April 1, 1987
Author(s)
Charles R. McLean
The software architecture of the cell control system in the Automated Manufacturing Research Facility (AMRF) at the National Bureau of Standards is presented. The cell control system manages production and support operations for an automated small batch

Control of an Automated Machining Workstation

April 1, 1987
Author(s)
Jay S. Jun, Charles R. McLean
The software architecture of the Vertical Machining Workstation (VWS) in the Automated Manufacturing Research Facility (AMRF) at the National Bureau of Standards is presented in this paper. This prototype system demonstrates flexible computer integrated

Measurement of the superconducting energy gap in La-Ba-Cu oxide and La-Sr-Cu oxide

April 1, 1987
Author(s)
Stephen E. Russek, P. E. Sulewski, A.J. Sievers, H. D. Hallen, D. K. Lathrop, R A. Buhrman
We report on far-infared (FIR) reflectivity measurements on sintered pressed poweder samples of La-Ba-Cu oxide and La-Sr-Cu oxide. THe best samples show fairly sharp transitions to zero measurable resistance with a transition midpoint of 28 K for the Ba
