Near-Field, Spherical-Scanning Antenna Measurements With Nonideal Probe Locations

October 12, 2021
Author(s)
Ronald C. Wittmann, Bradley Alpert, Michael H. Francis
We introduce a near-field, spherical-scanning algorithm for antenna measurements that relaxes the usual condition requiring data points to be on a regular spherical grid. Computational complexity is of the same order as for the standard (ideal-positioning)

Fire Dynamics Simulator (Version 4) - Technical Reference Guide

March 1, 2006
Author(s)
Kevin B. McGrattan
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The software described in this document solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an

A Representation of Acoustic Waves in Unbounded Domains

October 1, 2002
Author(s)
Bradley K. Alpert, Yu-Hsuan Chen
Compact, time-harmonic, acoustic sources produce waves that decay too slowly to be square-integrable on a line away from the sources. We introduce an inner product, arising directly from Green's second theorem, to form a Hilbert space of these waves, and

Measuring Performance and Intelligence of Intelligent Sytems White Paper 2001

August 4, 2001
Author(s)
Elena R. Messina, Alex Meystel, Larry H. Reeker
Is the measurement of performance for intelligent systems different than that of non-intelligent systems? In this white paper, we explore the various dimensions of evaluation of intelligence and performance. The main areas we tackle are the testing of

Report of Scoping the Apparel Manufacturing Enterprise

May 1, 1993
Author(s)
Howard T. Moncarz, Yung-Tsun Lee
This paper identifies a set of manufacturing data interfaces that could be standardized for the effective computer integration of the information required to operate an apparel manufacturing enterprise. The interfaces are called Application Protocols. A

Data-driven approaches to optical patterned defect detection

September 5, 2019
Author(s)
Mark-Alexander Henn, Hui Zhou, Bryan M. Barnes
Computer vision and classification methods have become increasingly popular in recent years due to ever-increasing computation power. While advances in semiconductor devices are the basis for this growth, few publications have probed the benefits of data

Quantum interference enables constant-time quantum information processing

July 19, 2019
Author(s)
Thomas Gerrits, Sae Woo Nam, Adriana E. Lita, M. Stobinska, A. Buraczewski, M. Moore, W.R. Clements, J.J. Renema, W.S. Kolthammer, A. Eckstein, I.A. Walmsley
It is an open question how fast information processing can be performed and whether quantum effects can speed up the best existing solutions. Signal extraction, analysis, and compression in diagnostics, astronomy, chemistry, and broadcasting build on the

CHARACTERIZING ENERGY CONSUMPTION OF THE INJECTION MOLDING PROCESS

June 14, 2013
Author(s)
Jatinder Madan, Mahesh Mani, Kevin W. Lyons
Presently available systems for sustainability assessment do not fully account for aspects related to a product’s manufacturing. In an effort to make more sustainable decisions, today’s industry seeks reliable methods to assess and compare sustainability

Measures, Uncertainties, and Significance Test in Operational ROC Analysis

January 31, 2011
Author(s)
Jin Chu Wu, Alvin F. Martin, Raghu N. Kacker
In operational ROC (receiver operating characteristic) analysis of fingerprint-image matching algorithms on large datasets, the measures and their accuracies are investigated in the three scenarios: 1) the true accept rate (TAR) of genuine scores at a

Validation of Two-Sample Bootstrap in ROC Analysis on Large Datasets Using AURC

October 11, 2010
Author(s)
Jin Chu Wu, Alvin F. Martin, Raghu N. Kacker
Sampling variability can result in uncertainties of measures. The nonparametric two-sample bootstrap method has been used to compute uncertainties of measures in receiver operating characteristic (ROC) analysis on large datasets, such as the standard error

Recognizing Small Circuit Structure in Two-Qubit Operators

March 20, 2003
Author(s)
V V. Shende, Stephen Bullock, I L. Markov
This work describes numerical tests which determine whether a two-qubit quantum computation has an atypically simple quantum circuit. Specifically, we describe forumulae, written in terms of matrix coefficients, characterizing operators implementable with
