Raman Spectroscopic Monitoring of Droplet Polymerization in a Microfluidic Device

September 1, 2006
Author(s)
Susan E. Barnes, Zuzanna T. Cygan, Kathryn Beers, Eric J. Amis, Jesse K. Yates
Thiolene based microfluidic devices were used to generate droplets of benzyl methacrylate monomer and hexanediol dimethacrylate crosslinker mixtures suspended in a water/surfactant continuous phase. A gradient of droplet composition was established and the

Round Robin Study of Total Heat Flux Gauge Calibration at Fire Laboratories.

September 1, 2006
Author(s)
William M. Pitts, A V. Murthy, J L. Deris, J R. Filtz, K Nygard, D Smith, I Wetterlund
Total heat flux gauges are widely employed in fire research and fire testing laboratories. Several fire laboratories have developed systems for calibrating these gauges. There are major differences between these calibration facilities, and prior to this

SAMATE's Contribution to Information Assurance

September 1, 2006
Author(s)
Paul E. Black
The amount of software in today's information world is far too large to check manually. Automated tools are a must. These tools can help design and build the right software in the first place, but they can also help if the system being designed includes

Smart Card Authentication for Mobile Devices

September 1, 2006
Author(s)
Wayne Jansen, Serban I. Gavrila, Clement Seveillac
While mobile handheld devices provide productivity benefits, they also pose new risks. User authentication is the best safeguard against the risk of unauthorized use and access to a device¿s contents. This paper describes two novel types of smart card with

Software Assurance During Maintenance

September 1, 2006
Author(s)
Paul E. Black
Software testing and maintenance tools must yield widely accepted assurance information in a standardized form. We can then use this information as evidence to make a case assuring us that the software is adequate for its use and secure enough for the risk

Spindle Health Diagnosis Based on Analytic Wavelet Enveloping

September 1, 2006
Author(s)
Li Zhang, Robert Gao, Kang B. Lee
A new diagnostic technique for identifying structural defects in spindles was developed, based on the analytic wavelet transform. The new technique extracts defect-induced impulses from the spindle vibration signal and constructs their envelopes in a

Standards for Plasma and Serum Protoemics in Early Cancer Detection: A Needs Assessment Report From the NIST-NCI SMART Workshop, August 18-19, 2005

September 1, 2006
Author(s)
Peter E. Barker, Paul D. Wagner, Stephen E. Stein, David M. Bunk, S Srivastava, Gilbert Omenn
The National Institute of Standards and Technology (NIST) and the National Cancer Institute (NCI) co-sponsored a workshop on August 18-19, 2005 to examine needs for reference materials to support biomarker discovery for early cancer detection. Needs for

Stationary Distributions in the Atom-on-Demand Problem

September 1, 2006
Author(s)
I Bebu, Andrew L. Rukhin
In this note a probability model for the number of atoms in a magneto-optical trap is suggested. We study an ergodic Markov Chain for the number of atoms in the trap under a feedback regime for different load distributions. Formulas for the stationary

Structural Characteristics of Methylsilsesquioxane Based Porous Low-k Thin Films Fabricated with Increasing Cross-Linked Particle Porogen Loading

September 1, 2006
Author(s)
Hae-Jeong Lee, Christopher L. Soles, Da-Wei Liu, Barry J. Bauer, Eric K. Lin, Wen-Li Wu
Methylsilsesquioxane (MSQ) based porous low-k dielectric films with different porogen loading have been characterized using X-ray porosimetry (XRP) to determine their pore size distribution, average density, wall density and porosity. By varying the

The Study of the U.S. Measurement System for Micro Nano Technologies

September 1, 2006
Author(s)
Richard A. Allen, Craig McGray, Michael Gaitan
The National Institute of Standards and Technology (NIST) has launched an ambitious assessment of the nation''s decentralized measurement system, that is far more encompassing than the few studies done over the last several decades. The aim is to determine
