MECHANICS OF ADHESION

June 1, 2011
Author(s)
Robert F. Cook
Abstract. A framework of increasing complexity is developed to describe the mechanics of adhesion and its reverse, de-adhesion or separation, during indentation contact cycles. The importance of the indentation probe stiffness in determination of system

Metrology Needs and NIST Resources for the Forensic DNA Community

June 1, 2011
Author(s)
Michael D. Coble, Margaret C. Kline, John M. Butler
With the advent of Forensic DNA profiling in the mid-1980s, this technology has had a positive impact on the criminal justice system, helping to convict the guilty and exonerate the innocent. The field has evolved from focusing on multi-locus markers

Multigate Communication Network For Smart Grid

June 1, 2011
Author(s)
Hamid Gharavi
It is envisioned that one of the most important issues in Smart Grid will be to design a network architecture that is capable of providing secure and reliable two-way communication from meters to other Smart Grid domains. While networking technologies and

Origin and Early History of Die Methode des Eichzusatzes or The Method of Standard Addition with Primary Emphasis on Its Origin, Early Design, Dissemination, and Usage of Terms

June 1, 2011
Author(s)
William R. Kelly, Kenneth W. Pratt, William F. Guthrie, Keith R. Martin
The Method of Standard Additions or the Standard Addition Method, often referred by its acronym as just SAM, is now a proverbial workhorse in both inorganic and organic quantitative analytical chemistry and in related disciplines such as geochemistry. Its

Pulse Metrology, Part 1

June 1, 2011
Author(s)
Nicholas G. Paulter Jr., Donald R. Larson
Pulse metrology refers to the science of the measurement of pulses, which are transient phenomena. This article describes concepts important for pulse metrology, namely, reproducibility and repeatability of measurement, measurement uncertainty, and

Scanning the Issue Smart Grid: The Electric Energy System of the Future

June 1, 2011
Author(s)
Hamid Gharavi
This is an editorial article for a special issue on smart grid. The main objective is to report on some, if not all, of smart grid future technical challenges. While acknowledging its limited coverage, this issue offers a wide range of interesting

Selective Pixel Interpolation for Spatial Error Concealment

June 1, 2011
Author(s)
Hamid Gharavi, Yi Ge, Bo Yan, Kairan Sun
This paper proposes an effective algorithm for spatial error concealment with accurate edge detection and partitioning interpolation. Firstly, a new method is used for detecting possible edge pixels and their matching pixels around the lost block. Then

Computer Security Division 2010 Annual Report

May 31, 2011
Author(s)
Patrick D. O'Reilly
This annual report covers the work conducted within the National Institute of Standards and Technology's Computer Security Division during Fiscal Year 2010. It discusses all projects and programs within the Division, staff highlights, and publications.

May 31, 2011
Author(s)
Liora Alschuler
The methodology described in this document was produced and developed by Lantana Consulting Group for the National Institute of Standards and Technology (NIST). It is part of a series of suitability analsyses on four healthcare standards performed under

Templated CDA:Key Concept for Interoperability

May 31, 2011
Author(s)
Liora Alschuler
This document supplements information about “templated CDA” in the context of the Healthcare Information Technology (HIT) Standards Analysis Project carried out by Lantana Consulting Group for the National Institute of Standards and Technology (NIST).

Mimicking Biological Design & Computing Principles in Artificial Olfaction

May 27, 2011
Author(s)
Baranidharan Raman, Stephen Semancik
Biology has been an inspiration for designing solutions to many engineering problems including chemical sensing. Modern approaches to chemical sensing have been based on the biological principle of combining cross-selective chemical sensors with a pattern

A Traceable Scatterometry Measurement of a Silicon Line Grating

May 26, 2011
Author(s)
Thomas A. Germer, Heather J. Patrick, Ronald G. Dixson
In this paper, we present a spectroscopic Mueller matrix ellipsometry measurement of a silicon line grating with nominal pitch of 600 nm and line width 100 nm. An uncertainty analysis is performed on the measurement results. The results are compared to

Effects of JPEG 2000 Image Compression on 1000ppi Fingerprint Imagery

May 26, 2011
Author(s)
Shahram Orandi, John M. Libert, John Grantham, Kenneth Ko, Stephen S. Wood, Jin Chu Wu
This paper presents the findings of a study conducted to measure the impact of JPEG 2000 compression on fingerprint imagery at various levels of compression. The impact of compression is measured in terms of impact to both Galton and non-Galton based

Effects of Roughness on Scatterometry Signatures

May 26, 2011
Author(s)
Martin Foldyna, Thomas Germer, Brent Bergner
We used azimuthally-resolved spectroscopic Mueller matrix ellipsometry to study a periodic silicon line structure with and without artificially-generated line edge roughness (LER). Grating profiles were determined from multiple azimuthal configurations

High-Resolution Passive Video-Rate Imaging at 350 GHz

May 26, 2011
Author(s)
Daniel T. Becker
We are developing a 350 GHz cryogenic passive video imaging system for use in standoff security applications. This demonstration system uses 800 photon-noise-limited superconducting transition edge sensor bolometers, read out using a time-division
