A Prototype IEEE 1451.4 Smart Transducer Interface for Sensors and Actuators

August 19, 2011
Author(s)
Yuyin Song, David M. Westbrook, Kang B. Lee
Analog transducers (sensors or actuators) are widely used in industry. The Institute of Electrical and Electronics Engineers (IEEE) 1451.4 standard defines a mixed-mode communication protocol and the Transducer Electronic Data Sheet (TEDS) formats for

Catalyst-free GaN nanowire growth and optoelectronic characterization

August 19, 2011
Author(s)
Kristine A. Bertness, Norman A. Sanford, John B. Schlager
We discuss the present state-of-the-art concerning the growth mechanism, optical luminescence and electrical properties for GaN nanowires grown with catalyst-free molecular beam epitaxy. These nanowires are essentially defect-free and display long

Accurate Nanometer-Scale Imaging and Measurements with SEM

August 18, 2011
Author(s)
Bradley N. Damazo, Bin Ming, Premsagar P. Kavuri, Andras Vladar, Michael T. Postek
Scanning electron microscopes (SEMs) are incredibly versatile instruments for millimeter to nanometer scale imaging and measurements of size and shape. New methods to improve repeatability and accuracy have been implemented on the so-called Reference SEMs

An Empirical Study of a Vulnerability Metric Aggregation Method

August 18, 2011
Author(s)
Su Zhang, Xinming Ou, Anoop Singhal, John Homer
Quantifying security risk is an important and yet difficult task in enterprise network risk management, critical for proactive mission assurance. Even though metrics exist for individual vulnerabilities, there is currently no standard way of aggregating

Determination of Fat-Soluble Vitamins and Carotenoids in Standard Reference Material 3280 Multivitamin/Multielement Tablets by Liquid Chromatography with Absorbance Detection

August 17, 2011
Author(s)
Jeanice M. Brown Thomas, Katherine Sharpless, Catherine Rimmer, James Yen
The concentrations of selected fat-soluble vitamins and carotenoids in Standard Reference Material (SRM) 3280 Multivitamin/Multielement Tablets have been determined by two independent liquid chromatographic methods with measurements performed by the

Dietary Supplement Laboratory Quality Assurance Program: The First Five Exercises

August 17, 2011
Author(s)
Melissa Phillips, Catherine Rimmer, Laura J. Wood, Katrice Lippa, Katherine Sharpless, David Duewer, Lane Sander, J. M. Betz
The National Institute of Standards and Technology (NIST) has established a Dietary Supplement Quality Assurance Program (DSQAP) in collaboration with the National Institutes of Health (NIH) Office of Dietary Supplements (ODS). Program participants measure

VISCOSITY AND DENSITY OF ALUMINUM OXIDE NANOLUBRICANT

August 17, 2011
Author(s)
Mark A. Kedzierski
This paper presents liquid kinematic viscosity and density measurements of a synthetic polyolester-based aluminum oxide (Al2O3) nanoparticle dispersion (nanolubricant) at atmospheric pressure over the temperature range 288 K to 318 K. The polyolester was a

4-bar-quasi-phasematching for second-harmonic generation in microdisks

August 15, 2011
Author(s)
Paulina S. Kuo, Glenn S. Solomon
We present a theoretical description of resonantly enhanced, 4-bar-quasi-phasematched, second-harmonic generation in microdisks made of materials possessing 4-bar symmetry, such as GaAs, GaP and ZnSe. The theory describes the interplay between quasi

A Note on Visualizing Smoke and Fire

August 15, 2011
Author(s)
Glenn P. Forney
Realistic visualization methods are important for applications where one wishes to observe data effects rather than examine data quantitatively. This note documents how the radiation transport equation (RTE) and associated numerical algorithms are used by
