Index of Refraction of Air

February 16, 2001
Author(s)
Jack A. Stone Jr., Jay H. Zimmerman
These Web pages are intended primarily as a computational tool that can be used to calculate the refractive index of air for a given wavelength of light and given atmospheric conditions (air temperature, pressure, and humidity). The calculations are

Textile Composites: Modeling Strategies

January 1, 2001
Author(s)
S V. Lomov, G Huysmans, Y Luo, Richard~undefined~undefined~undefined~undefined~undefined Parnas, A Prodromou, I Verpoest, Frederick R. Phelan Jr.
Textile materials are characterised by the distinct hierarchy of structure, which should be represented by a model of textile geometry and mechanical behaviour. In spite of a profound investigation of textile materials and a number of theoretical models

Percolation Aspects of Cement Paste and Concrete - Properties and Durability

August 1, 2000
Author(s)
Edward J. Garboczi, Dale P. Bentz
Synopsis: Portland cement concrete is a composite material, where the matrix consists of portland cement paste. Cement paste forms from the hydration reaction of portland cement with water. The microstructure of cement paste changes drastically over a time

Design for Tolerance of Electro-Mechanical Assembles

January 1, 1998
Author(s)
Sudarsan Rachuri, Yadati Narahari, Kevin W. Lyons, M R. Duffey
Tolerancing decisions during the design of electromechanical products profoundly affect cost and quality. Existing approaches to tolerance analysis and synthesis entail detailed knowledge of geometry of the assemblies and are mostly applicable during

Sources of Uncertainty for Near-Field Measurements

November 11, 2007
Author(s)
Michael H. Francis, Ronald C. Wittmann
We discuss the sources of uncertainty in near-field measurements and their impact on far-field antenna parameters. The methods of estimating these uncertainties can be considered in three broad categories: theoretical estimation (analytical), computer

The NIST EXPRESS Toolkit: Introduction and Overview

October 1, 1993
Author(s)
Donald E. Libes
The NIST EXPRESS Toolkit is a software library for building EXPRESS-related tools. This paper gives an introduction, overview, and history of the toolkit. This paper also describes how to get more information on the toolkit. No knowledge of EXPRESS or the

POLYMER99 - NIST Polymers Division Published Works for 1999

October 16, 2008
Author(s)
J D. Barnes, B M. Fanconi, Eric J. Amis
This publication is a compilation of 104 documents that were published by staff of the NIST Polymers Division during Calendar year 1999. The documents are in a Portable Document Format (PDF) so that they can be read on most computers. Indexes and

Volume Visualization of Bose-Einstein Condensates

April 1, 2001
Author(s)
Peter M. Ketcham, D L. Feder, Charles W. Clark, Steven G. Satterfield, Terence J. Griffin, William L. George, Barry I. Schneider, W P. Reinhardt
Theoretical aspects of Bose-Einstein condensates are investigated by conducting computer simulations of their behavior. Scientific visualization techniques are employed in order to examine the large amount of data generated by simulation. Visualization of

Temporal Memory with Magnetic Racetracks

December 1, 2020
Author(s)
Hamed Vakili, Mohammed N. Sakib, Samiran Ganguly, Mircea Stan, Matthew Daniels, Advait Madhavan, Mark D. Stiles, Avik W. Ghosh
Race logic is a relative timing code that represents information in a wavefront of digital edges on a set of wires in order to accelerate dynamic programming and machine learning algorithms. Skyrmions, bubbles, and domain walls are mobile magnetic
