OOMMF User's Guide, Version 1.0

September 1, 1999
Author(s)
Michael J. Donahue
This manual describes OOMMF (Object Oriented Micromagnetic Framework), a public domain micromagnetics program developed at NIST. The program is designed to be portable, flexible, and extensible, with a user-friendly graphical interface. The code is written

Photometry The CIE V(l) Function and What Can Be Learned from Photometry

September 1, 1999
Author(s)
Yoshihiro Ohno, E A. Thompson
The V(l) function, used in photometry, is an average action spectrum for the visual response of the human eye, and the matching of the spectral responsivity of photometers to V(l) is the most important criterion of photometers. Techniques have been

Polarization Distribution in Ceramic-Polymer Nanocomposites

September 1, 1999
Author(s)
P Bloss, A S. DeReggi, H J. Glasel, E Hartmann, D Hirsch, H Schafer
We report pyroelectric responsivity versus depth profiles in nanocomposites of powdered barium titanate and tripropylene glycol diacrylate obtained by using the thermal pulse (TP) method. The ceramic nanopowder (mean particle size 270 nm) was prepared by

Radiometric Measurement Comparisons Using Transfer Radiometers in Support of the Calibration of NASA's Earth Observing System (EOS) Sensors

September 1, 1999
Author(s)
James J. Butler, B. Carol Johnson, Steven W. Brown, Howard Yoon, R Barnes, B L. Markham, S F. Biggar, E F. Zalewski, P R. Spyak, J W. Cooper, F Sakuma
EOS satellite instruments operating in the visible through the shortwave infrared wavelength regions (from 0.4 um to 2.5 um) are calibrated prior to flight for radiance using integrating spheres at a number of instrument builder facilities. The

Spectroscopic Ellipsometry of Ta 2 0 5 On Si, in Ultrathin SiO 2 and High-K Materials for ULSI Gate Dielectrics, edited by H. R. Huff, C. A. Richter, M. L. Green, G. Lucovsky, and T. Hattori

September 1, 1999
Author(s)
Curt A. Richter, Nhan Van Nguyen, G A. Alers
In this paper, we present the results of spectroscopic ellipsometry (SE) studies of Ta 20 5 films on Si. Based on these results, we have experimentally determined an effective method for analyzing SE measurements of Ta 20 5. A set of CVD-grown Ta 20 5

Standards-Based Software Testing in a Net-Centric World

September 1, 1999
Author(s)
KC Morris, David Flater
Automation for product development and manufacturing is changing to take advantage of the recent expansion of the Internet and the computing technologies supporting it. These processes are becoming more software independent, and the software used is

Structured Markup on the Web: A Tale of Two Sites

September 1, 1999
Author(s)
Joshua Lubell
Business and organizations are increasingly finding that HTML (Hyper-Text Markup Language)offers no help whatsoever in managing the information on their web sites. SGML (Standard Generalized Markup Language) provides the flexibility and reuse lacking in

Switching Mechanism of Single Domain Particles in a Two-Dimensional Array

September 1, 1999
Author(s)
Martha Pardavi-Horvath, G Vertesy, B Keszei, Z Vertesy, Robert D. McMichael
The mechanism of switching of uniaxial, single domain, single crystalline epitaxial garnet particles on a 2D square array was investigated. The anisotropy field of the sample is 2 kOe, while the gaussian switching field distribution is 280 85 Oe. The

The Representation of Function in Computer-Based Design

September 1, 1999
Author(s)
Simon Sykman, Ram D. Sriram, J Racz
This paper proposes a standardized representation of function for use by the research community, industry, and eventually commercial software vendors. This includes schemata (information models) for representation of function and associated flows, as well

The Use of XML to Describe Function and Taxonomies in Computer-based Design

September 1, 1999
Author(s)
Simon Sykman, Ram D. Sriram, Jocelyn Senfaute
This paper presents a mapping of a standardized representation of a function, consisting of schemata for functions and associated flows. Along with taxonomies of generic functions and flows, into the Extensible Markup Language (XML). A language similar in

Thermophysical Properties of Natural Refrigerants

September 1, 1999
Author(s)
Joe W. Magee
Natural refrigerants are candidates to replace halogenated hydrocarbons as working fluids in refrigeration systems. This class of substances is loosely defined to include carbon dioxide, ammonia, water, air, nitrogen, hydrogen, helium, light hydrocarbons
