Toward Self-Integrating Software Applications for Supply Chain

August 1, 2001
Author(s)
Michael Gruninger, Nenad Ivezic, Albert W. Jones
Each paper in this special issue deals with a particular aspect of supply chain management. Nevertheless, they all point to a common need for meaningful and timely information exchange across the supply chain. The Internet and the existing Web technologies

Understanding TREC Results - the Role of Statistics

August 1, 2001
Author(s)
Walter S. Liggett Jr, Paul D. Over
The challenge in empirical development of information retrieval systems at TREC is obtaining general conclusions from IR system responses to a sample of perhaps 50 topics, that is, 50 statements of information need. Treating such a sample as a simple

Basic Procedures in Force Calibration at NIST

July 29, 2001
Author(s)
Ricky L. Seifarth, Samuel L. Ho
Force calibrations obtainable at the National Institute of Standards and Technology (NIST) continue to focus on extracting the maximum performance from the primary force standard deadweight machines, the ratiometric electrical readout systems and the

The Effect of Query Choice on Information Retrieval

July 20, 2001
Author(s)
Walter S. Liggett Jr, C E. Buckley
Analysis of the Query Track of the Eighth Text Retrieval Conference (TREC-8) shows how the presence or absence of a word or two in a query can make a large difference in information retrieval performance. The Query Track contains results from 8 systems

PVT Measurements for Toluene in the Near-Critical and Supercritical Regions

July 19, 2001
Author(s)
Asbat E. Bazaev, Ilmutdin Abdulagatov, Joe W. Magee, Emil Bazaev, Michail Rabezkii
The PVT relationships of toluene were measured in the near-critical and supercritical regions. Measurements were made using a constant-volume peizometer immersed in a precision thermostat. The volume of the piezometer V PT was corrected for both

The Policy Machine for Security Policy Management

July 17, 2001
Author(s)
Chung Tong Hu, Deborah A. Frincke, David F. Ferraiolo
Many different access controls policies and models have been developed to suit a variety of goals: these include Role-Based Access Control, One-directional Information Flow, Chinese Wall, Clark-Wilson, N-person Control, and DAC, in addition to more

Study of Moisture and Binder Content of Spray Dried Alumina Granules

July 16, 2001
Author(s)
James F. Kelly, S Jahanmir
A round robin testing program for IEA Annex II Subtask 12 was carried out to test procedures for measurement of moisture and binder content of alumina granules. The granules provided by Japan, were produced with 1.0% binder by mass and contained

A Capacitance Measurement System Using an Inductive Voltage Divider (IVD) Bridge

July 1, 2001
Author(s)
Bryan C. Waltrip, Andrew D. Koffman, S. Avramov
A new system to characterize the magnitude and phase characteristics of 1 pF to 1 uF capacitance standards over the 50 Hz to 100 kHz frequency range is described. The system has been developed to provide measurement support for LCR meters and general

A Genetic Programming System with a Procedural Program Representation

July 1, 2001
Author(s)
John G. Hagedorn, J E. Devaney
We describe the status of a genetic programming system that is based on a procedural program representation. The procedural representation is closely related to the high level programming languages used by human programmers; it includes features such as

A Predictive Ionization Cross Section Model for Inorganic Molecules

July 1, 2001
Author(s)
John W. Hastie
To resolve a long-standing lack of experimental data for electron impact ionization cross sections for inorganic molecules, or the availability of a reliable predictive method, we have developed a modified classical model. The model relies on the know or
