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

Wideband Large-Signal RF Measurements Applied to Behavioral Model Extraction

September 1, 2006
Author(s)
Kate Remley, M. Myslinski, Dominique Schreurs, Bart Nauwelaers
This work presents for the first time wideband Large Signal Network Analyzer (LSNA) measurements used to extract a large-signal behavioral model of an RF amplifier. The methodology together with some important issues concerning the data processing is

Personal Identity Verification Demonstration Summary

August 31, 2006
Author(s)
Erika McCallister, Hildegard Ferraiolo
This paper provides a summary of the NIST Personal Identity Verification (PIV) Demonstration. The PIV Demonstration took place from May 15 to June 14, 2006. Forty-four companies voluntarily participated through a Cooperative Research and Development

THE LAGR PROJECT - Integrating Learning Into the 4D/RCS Control Hierarchy

August 31, 2006
Author(s)
James S. Albus, Roger V. Bostelman, Tsai H. Hong, William P. Shackleford, Michael O. Shneier
The National Institute of Standards and Technology s (NIST) Intelligent Systems Division (ISD) has been a part of the Defense Advanced Research Project Agency (DARPA) LAGR (Learning Applied to Ground Robots) Project. The NIST team s objective for the LAGR

Comparison of MPEG-2 and AVC Coding on Synthetic Test Materials

August 30, 2006
Author(s)
Charles D. Fenimore, John W. Roberts
The available resources for evaluation of moving imagery coding include a variety of subjective and objective methods for quality measurement. These are applied to a variety of imagery, ranging from synthetically-generated to live capture. NIST has created

Multiple Description Video Coding Over Multiple Path Routing Networks

August 29, 2006
Author(s)
Shaoshuai Gao, Hamid Gharavi
This paper presents a multiple description (MD) video-coding scheme, which uses interlaced high signal to noise ratio (H-SNR) and low signal to noise ratio (L-SNR) coded frames to produce two bit-streams. At the decoder, when both bit-streams are received

Analysis of Admixed CeO 2 Nanoparticles via TEM and X-Ray Diffraction Techniques

August 28, 2006
Author(s)
Andrew Vella, Rhys Whitley, N G. Armstrong, A Dowd, James Cline
The techniques used to identify nanoparticle size and shape characteristics are of vital importance in the development of functional nanoparticles. Each technique offers different advantages; this work compares the two techniques of transmission electron

A single-photon pump

August 25, 2006
Author(s)
Kevin Osborn, Mark W. Keller
We describe a gated quantum dot device called a single-photon pump that produces single photons on demand through the controlled tunneling of individual electrons and holes. Simulations using an InGaAs/GaAs dot show that two modes of operation are possible

HEMT Amplified SET Measurements of Individual InGaAs Quantum Dots

August 25, 2006
Author(s)
Kevin Osborn, Mark W. Keller, Richard Mirin
A High Electron Mobility Transistor (HEMT) is used with a Single Electron Transistor (SET) to measure single electrons tunnelling into individual InGaAs quantum dots. The SET detects the charge motion as an electron tunnels from an underlying n-doped layer
