Modeling Information for Manufacturing-Oriented Supply-Chain Simulation

August 1, 2004
Author(s)
Guixiu Qiao, Frank H. Riddick
This paper discusses a new approach that facilitates the use of simulation in supply chain applications, especially for manufacturing-related activities. A neutral information representation methodology, which is based on the eXtensible Markup Language

Near-Field Polarimetric Characterization of Polymer Crystallites

August 1, 2004
Author(s)
Lori S. Goldner, S N. Goldie, Michael J. Fasolka, F Renaldo, Jeeseong Hwang, Jack F. Douglas
We use near-field polarimetry (NFP) to investigate thin film crystallites of isotactic polystyrene (iPS). NFP micrographs enabled quantitative optical characterization of the birefringence in these specimens with sub-diffraction limited resolution

Optical Excitation and Absorption Spectra of C 50 Cl 10

August 1, 2004
Author(s)
Rui-Hua Xie, Garnett W. Bryant, J Cheung, V H. Smith, J Zhao
Recent experiment has synthesized C 50Cl 10 [S.Y. Xie et al., Science 304, 699 (2004)] in a large quantity capturing the labile fullerene C 50. In this Communication, we report ab initio calculations on the optical excitation and absorption spectra of C

Organogelators and Their Application in Dental Materials

August 1, 2004
Author(s)
Elizabeth Wilder, Janet Quinn, Joseph M. Antonucci
Dibenzylidene sorbitol (DBS) is an organic molecule capable of inducing physical gelation in a wide variety of organic solvents and polymer melts by forming three-dimensional networks. Recent efforts in this laboratory have found that DBS is capable of

PC Modeling and Simulation Guidelines: Volume 1 - Overview

August 1, 2004
Author(s)
Charles R. McLean, Frank H. Riddick
The Navy is preparing to make significant investments in personal computer (PC) simulation-based learning systems. Presenting learning material in various formats and taking advantage of multimedia technologies has been shown to greatly benefit the learner

PDA Forensic Tools: an Overview and Analysis

August 1, 2004
Author(s)
Richard Ayers, Wayne Jansen
Adequate user authentication is a persistent problem, particularly with mobile devices such as Personal Digital Assistants (PDAs), which tend to be highly personal and at the fringes of an organization's influence. Yet these devices are being used

Phase Equilibria of Ba-R-Cu-O-F-OH for Coated-Conductor Applications (R=Lanthanides and Y)

August 1, 2004
Author(s)
Winnie K. Wong-Ng, Lawrence P. Cook, Igor Levin, J Suh, Ron Feenstra, T J. Haugan, P. D. Barnes
Phase diagrams of the Ba 2RCu 3O 6+x (R=Nd, Sm, Gd, Y, and Er) superconductors, prepared under 0.1 % 0 2 at 810 C, reflect the trend of the lanthanide contraction. The single-phase regions of Ba 2-x(Nd 1+x-yR y) Cu 3O 6+z for R=Gd, Y and Yb, and Ba 2-x(R 1

Proceedings of the Biometric Consortium Conference 2003, Vol 1, No 2)

August 1, 2004
Author(s)
Fernando L. Podio, J S. Dunn
This document contains the proceedings from the 2003 Biometric Consortium Conference held September 22-24, 2003, in Arlington, Virginia. The conference provides a forum to discuss government and commercial implementations and initiatives and recent

Quantum-Based Microwave Power Measurements: Proof-of-Concept Experiment

August 1, 2004
Author(s)
Thomas P. Crowley, E. A. Donley, T P. Heavner
An initial proof-of-concept experiment to measure microwave power based on quantum-mechanical principles is presented. Ground state cesium atoms exposed to 9.192631770 GHz microwave oscillate between two hyperfine states at a rate that is proportional to

R-22 Replacement Status

August 1, 2004
Author(s)
J M. Calm, Piotr A. Domanski
The next step in the transition to environmentally safer refrigerants is phase out of R-22. It is the most widely used refrigerant, both in the United States and on a global basis. Its application range in residential, commercial, industrial, and transport

Relativity of Explicit Conceptual Models

August 1, 2004
Author(s)
David W. Flater
Explicit conceptual models are supposed to capture knowledge of lasting value in a reusable form. Reuse of explicit conceptual models is hampered by arbitrary and application-specific constraints; any constraints that conflict with a new application must

Requirements on Information Technology for Product Lifecycle Management

August 1, 2004
Author(s)
Peter O. Denno, T Thurman
Good decision-making is founded on good information. Information technology supporting product lifecycle management ought to provide a high degree of information cohesion and traceability ? knowledge of the interrelations among data, and basis for belief

Standard Reference Material 1751 - A Gallium Melting-Point Standard

August 1, 2004
Author(s)
Gregory F. Strouse
The melting point of gallium %2829%2E7646%B0C%29 is a defining thermometric fixed point of the International Temperature Scale of 1990 %28ITS%2D90%29%2E Realization of this melting point is performed using a fixed%2Dpoint cell containing high%2Dpurity

Statistical Analysis of Key Comparisons with Linear Trends

August 1, 2004
Author(s)
Nien F. Zhang, Hung-Kung Liu, N Sedransk, W Strawderman
A statistical analysis for Key Comparisons with linear trend is proposed. The approach has the advantage that it is consistent with the case in which there is no trend. The uncertainties for KCRV and the degrees of equivalence are also provided. As an
