Diagnostics for Light Measuring Devices in Flying-spot Display Measurements

January 31, 2000
Author(s)
Paul A. Boynton, Edward F. Kelley, S. Highnote, R. Hurtado
Flying-spot displays, such as some laser projection displays, use a high-energy beam as a light source that scans the image across the display screen. Each pixel can be a narrow, high-energy pulse. When such displays are measured with convential light

Unified Advanced CD-SEM specification for Sub-0.18um Technology (1999 Version)

January 31, 2000
Author(s)
J Allgair, C Archie, W Banke, H Bogardus, A Delaporte, Michael T. Postek, J Schlesinger, B Singh, Andras Vladar, A Yanof
The Advanced Metrology Advisory Group (AMAG) comprised of representatives from: the International SEMATECH (ISEMATECH) consortium member companies; the National Institute of Standards and Technology; and ISEMATECH assignees have joined to develop a unified

Design of 3-D Visualization of Search Results: Evolution and Evaluation

January 25, 2000
Author(s)
John V. Cugini, Sharon J. Laskowski, M M. Sebrechts
We discuss the evolution of the NIST Information Retrieval Visualization Engine (NIRVE). This prototype employs modern interactive visualization techniques to provide easier access to a set of documents resulting from a query to a search engine. The

Orientation of Surface Bound Proteins Studied by Near Edge X-Ray Absorption Fine Structure

January 25, 2000
Author(s)
L Gamble, J R. Long, P S. Stayton, Daniel A. Fischer, S Sambasivan, David G. Castner
The orientation of surface bound proteins may play an important role in the function and properties of materials to which they are adsorbed. Near edge absorption fine structure (NEXAFS) is a technique which allows the user to determine the presence of

The Case for Simulation-Based Evaluation of Ubiquitous Computing Environments

January 25, 2000
Author(s)
Alden A. Dima, L P. Clarletta
Ubiquitous computing (a.k.a. pervasive computing) is ill-defined due to its novelty and the community's current emphasis on its technological aspects. This can lead to serious \existential issues during the evaluation of ubiquitous computing technologies

Assurance Protocols and Small Web Retailers

January 24, 2000
Author(s)
Gordon E. Lyon
Many Web areas are in an early technological period of rapid evolution and intense competitive selection. Nowhere is this truer than with electronic commerce. While much is being considered today for business-to-business transactions, the Web also

Ab-Initio Energetics of Transition Metal Ordering in Decagonal Al-Co-Cu

January 21, 2000
Author(s)
M Widom, I Al-Lehyani, Yijun Wang, Eric J. Cockayne
We perform ab-initio total energy calculations for approximants to a model of decagonal A1CoCu. These calculations support previously proposed chemical ordering of Co and Cu atoms along tile edges. Preferred arrow orientations are identified and shown to

Generation of Quasicrystals Via a Single Cluster

January 21, 2000
Author(s)
Eric J. Cockayne
We present a columnar cluster with 46 atoms per repeat distance which forces a quasicrystal when space is filled by interpenetrating copies of itself. The atomic positions in the resultant quasicrystal are remarkably similar to those in models for real

Pressure Dependence of Instabilities in Perovskite PbZrO 3

January 21, 2000
Author(s)
Eric J. Cockayne, K M. Rabe
We have computed the frequencies of selected normal modes in perovskite PbZrO 3 (PZ) as a function of lattice parameter using local density functional theory variational linear response. The most significant instabilities that freeze in to give the

In Situ Characterization of Catalytic Propylene Oxidation on the Pt (111) Surface

January 17, 2000
Author(s)
A M. Gabelnick, A T. Capitano, D J. Burnett, Daniel A. Fischer, J L. Gland
The catalytic oxidation of propylene with both propylene and oxygen in the gas phase has been characterized on the Pt(111) surface. In situ soft x-ray kinetic and spectroscopic measurements using fluorescence detection have been used to characterize this

Gapless Mean-Field Theory of Bose-Einstein Condensation

January 15, 2000
Author(s)
D A. Hutchinson, Karen G. Burnett, K Dodd, S A. Morgan, M Rusch, M Zaremba, N P. Proukakis, A Griffin, Mark A. Edwards, Charles W. Clark
We present a topical review of the development of finite-temperature field theories of Bose-Einstein condensation in weakly interacting atomic gases. We highlight the difficulties in obtaining a consistent finite-temperature theory that has a gapless

Converting System Failure Histories Into Future Win Situations

January 7, 2000
Author(s)
D Wallace, David R. Kuhn
Most complex systems today contain software, and systems failures activated by software faults can provide lessons for software development practices and software quality assurance. This paper presents an analysis of software-related failures of medical

A User's Guide for FAST: Engineering Tools for Estimating Fire Growth and Smoke Transport

January 3, 2000
Author(s)
Richard D. Peacock, Paul A. Reneke, Walter W. Jones, Richard W. Bukowski, Glenn P. Forney
FAST is a collection of fire modeling tools which uses the underlying fire model CFAST and adds the routines of FIREFORM to provide engineering calculations of fire phenomena in compartmented structures. This manual provides documentation and examples for
