Domain Images of Ultrathin Fe Films on Ag(100)

May 30, 1988
Author(s)
J L. Robins, Robert Celotta, john unguris, Daniel T. Pierce, B Jonker, G Prinz
Scanning electron microscopy with electron polarization analysis has been used to image domains of ultrathin Fe films grown epitaxially on a Ag(100) substrate. Room-temperature measurements show clearly the existence of large domains of in-plane

Message Authentication Code (MAC) Validation System: Requirements and Procedures

May 1, 1988
Author(s)
Miles E. Smid, Elaine B. Barker, David Balenson, Martha E. Haykin
The National Bureau of Standards Message Authentication Code (MAC) Validation System (MVS) tests message authentication devices for conformance to two data authentication standards: Federal Information Processing Standard Publication (FIPS PUB) 113,

Exploiting Computational Parallelism with a Hierarchical Robot Control System

April 29, 1988
Author(s)
John L. Michaloski, Thomas E. Wheatley, Ronald Lumia
Sequential machines do not provide enough computational perfomance for a real-time robot control system. Hierarchical structuring will be considered not only as a software development methodology, but also as a means for implementing a robot control system

Analysis of the Influence of Piston Effect on Elevator Smoke Control

April 1, 1988
Author(s)
J H. Klote
This paper is part of a joint project between the United States and Canada to evaluate the feasibility of using elevators for the evacuation of the handicapped during a fire. The transient pressures produced when an elevator car move in a shaft are a

Electron Spin Polarization Analyzers for Use with Synchrotron Radiation

April 1, 1988
Author(s)
Daniel T. Pierce, Robert Celotta, Michael H. Kelley, John Unguris
The measurement of the spin polarization of photoelectrons emitted from a magnetic material is discussed. An important consideration is the acceptance phase space of the spin analyzer relative to the phase space of the photoemitted electrons to be measured
