Stark Spectroscopy at Metal Surfaces

August 1, 2000
Author(s)
Adolfas Gaigalas, Lili Wang
The paper summarizes the theoretical and experimental work on the effects of electric fields on the spectroscopic properties of molecules confined at metal electrodes. Both absorption and fluorescence are discussed in a unified manner. The first order

Status of the Revision of ASHRAE Standard 62

August 1, 2000
Author(s)
Andrew K. Persily
The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is in the process of revising Standard 62 Ventilation for Acceptable Indoor Air Quality. Because Standard 62 has been designated as a high profile standard by ASHRAE

Strength Evaluation of Connectors for Intermodal Containers

August 1, 2000
Author(s)
Hai S. Lew, Fahim Sadek, E D. Anderson
Intermodal containers are used widely in marine cargo handling. In order to facilitate unloading of empty containers from ship to shore, two containers are lifted frequently in tandem. This operation is referred to as vertical tandem lifting. In this

Suppression of Fatigue Cracking With Nanometer-Scale Multilayered Coatings

August 1, 2000
Author(s)
Mark R. Stoudt, R C. Cammarata, Richard E. Ricker
(Scripta Materialia doesn't use an Abstract -- Took 1st sentence of Intro) Fatigue crack initiation in initally smooth samples of ductile metals free of surface defects almost always occurs at the free surface a sa result of surface rioughening and the

The Effect of Anisotropy on the Second Virial Coefficient of H 2

August 1, 2000
Author(s)
Allan H. Harvey, M P. Hodges
Recently, Diep and Johnson 1 developed a pair potential for H 2-H 2 fitted to ab initio calculations at the coupled-cluster (CCSD(T)) level extrapolated to the complete basis set limit. They compared second viral coefficients B(T) from their potential to

The Fundamental Physical Constants

August 1, 2000
Author(s)
Peter J. Mohr, Barry N. Taylor
The Committee on Data for Science and Technology (CODATA) was established in 1966 as an interdisciplinary committee of the International Council of Science (ICSU, formerly the International Council of Scientific Unions). Soon thereafter, in 1969, CODATA

The IMS Mission Architecture for Distributed Manufacturing Simulation

August 1, 2000
Author(s)
Frank H. Riddick, Charles R. McLean
This paper presents an overview of a neutral reference architecture for integrating distributed manufacturing simulation systems with each other, with other manufacturing software applications, and with manufacturing data repositories. Other manufacturing

The NIST RS274NGC Interpreter - Version 3

August 1, 2000
Author(s)
Thomas R. Kramer, Frederick M. Proctor, Elena R. Messina
This report describes an interpreter which reads numerical control code and produces calls to a set of canonical machining functions. The interpreteris a software system written in the C++ programming language. The output of the interpreter may be used to

Theory of Four-Wave Mixing of Matter Waves from a Bose-Einstein Condensate

August 1, 2000
Author(s)
M Trippenbach, Y B. Band, Paul S. Julienne
A recent experiment [Deng et al., Nature 398, 218 (1999)] demonstrated the four-wave mixing of matter wavepackets created from a Bose-Einstein condensate. The experiment utilized light pulses to create two high-momentum wavepackets via Bragg diffraction

Time Synchronized Measurements in Cluster Computing Systems

August 1, 2000
Author(s)
Alan Mink, Robert J. Carpenter, M M. Courson
We describe hardware time synchronization instrumentation that we have developed which achieves time synchronization of better than one microsecond. The purpose of this instrumentation is for Quality of Service characterization of parallel and distributed

Ventilation Strategies for U.S. Manufactured Homes

August 1, 2000
Author(s)
S R. Martin, Andrew K. Persily
The HUD Manufactured Home Construction and Safety Standards contain requirements intended to provide adequate levels of outdoor air ventilation in U.S. manufactured homes. In the implementation of these standards, questions have arisen regarding the impact

Vortex Pinning in Microindented Yba 2 Cu 3 O 7-x Single Crystals

August 1, 2000
Author(s)
Marina Turchinskaya, Douglas T. Smith, Alexander L. Roytburd, Debra L. Kaiser
A high resolution magneto-optical technique with a magnetic indicator film was used to study the effect of a regular array of micrometer-sized mechanical indentations on magnetization dynamics at the surface of a twinned single crystal of Yba 2Cu 3O 7-δ as

Wind-Induced Peak Bending Moments in Low-Rise Building Frames

August 1, 2000
Author(s)
M Gioffre, Mircea Grigoriu, M Kasperski, Emil Simiu
We present a procedure for estimating peaks of non-Gaussian processes representing fluctuating internal forces induced by wind in low-rise building frames. The procedure is designed for inclusion in computer programs that use surface pressure data bases to
