X-Ray Transition Energies -- New Comprehensive Evaluation

June 1, 1998
Author(s)
R Deslattes, Ernest G. Kessler, Paul Indelicato, E Lindroth
In this brief report we describe some of the background for our continuing efforts toward a new comprehensive data base for x-ray transitions, and indicate the present status of this effort, one that is still a work in progress. In contrast to previous

Quality Control Procedures for the NIST/EPA/NIH Mass Spectral Library

May 31, 1998
Author(s)
C L. Clifton, S G. Lias, Anzor I. Mikaia, O D. Sparkman, Stephen Stein, Dmitrii Tchekhovskoi, Damo Zhu, Vladimir G. Zaikin
The goal of quality control procedures is to produce the best possible spectra for library searching. The role of a panel of data evaluators is presented, and the plans for further improvements of the NIST/EPA/NIH mass spectral library is presented.

Software Testing: Protocol Comparison

May 29, 1998
Author(s)
James H. Yen, D L. Banks, Leonard J. Gallagher, Paul E. Black, Robert C. Hagwood, Raghu N. Kacker, Lynne S. Rosenthal
Software testing is hard, expensive, and uncertain. Many protocols have been suggested, especially in the area of conformance verification. In order to compare the efficacy of these protocols, we have implemented a designed simulation experiment that

Water Additives for Increased Efficiency of Fire Protection and Suppression

May 28, 1998
Author(s)
Daniel M. Madrzykowski
The Building and Fire Research Laboratory at the National Institute of Standards and Technology, under the sponsorship of the United States Fire Administration, has examined methods for demonstrating the fire protection and suppression effectiveness of

Adapting to Bandwidth Variations in Wide-Area Data Combination

May 26, 1998
Author(s)
Mudumbai Ranganathan, A Acharya, J Saltz
Efficient data combination over wide-area networks is hard as wide-area networks have large variations in available network bandwidth. In this paper, we examine the utility of changing the location of combination operators as a technique to adapt to

Replicated Architecture for Application Sharing in Desktop Conferencing Systems

May 26, 1998
Author(s)
J B. West, P Kabore, Okhee Kim, J Favreau
Multimedia desktop conferencing systems are gaining momentum and increasingly becoming a reality. In these systems, besides using audio, video and multi-user applications like a white board, users can share a vast number of single-user applications for

High bandwidth-efficiency resonant cavity enhanced Schottky photodiodes for 800-850 nm wavelength operation

May 25, 1998
Author(s)
M. S. {Umlat}nl{umlat}, M. Gvkkavas, B. M. Onat, E. Ata, E. Vzbay, Richard Mirin, K. J. Knopp, Kristine A. Bertness, David H. Christensen
High-speed resonant cavity enhanced Schottky photodiodes operating in 800-850 nm wavelength region are demonstrated. The devices are fabricated in the AlGaAs/GaAs mate1ial system. The Schottky contact is a semitransparent Au film which also serves as the

Observation of antiparallel magnetic order in weakly coupled Co/Cu multilayers

May 23, 1998
Author(s)
Julie Borchers, Joseph Dura, John Unguris, D Tulchinsky, Michael H. Kelley, Charles Majkrzak, S. Y. Hsu, R Loloee, W Pratt, J Bass
Polarized neutron reflectivity and scanning electron microscopy with polarization analysis are combined to determine the magnetic structure of Co(6 nm)/Cu(6 nm) multilayers. These data resolve a controversy regarding the low-field state of giant

An Apparatus for Evaluating Liquid Fire Suppressants

May 12, 1998
Author(s)
Jiann C. Yang, Michelle K. Donnelly, William L. Grosshandler, N C. Prive
Cup burners have been extensively used as a fire suppression efficiency screening tool for gaseous halon alternatives. In the search for alternatives to halons in fire suppression, it is likely that several types of condensed-phase compounds will be

Completing Our Panel's Work.

May 12, 1998
Author(s)
Richard N. Wright
Our 30th Joint Meeting provides an opportunity to reflect on our work and accomplishments and establish our view for the future of our U.S./Japan Panel on Wind and Seismic Effects. The Panel has helped us, in the United States, in Japan, and in the world
