HIGHLY CHARGED ION INTERACTIONS WITH THIN INSULATING FILMS

June 1, 2011
Author(s)
Joshua M. Pomeroy, Russell E. Lake, C E. Sosolik
The electrical conductance of magnetic tunnel junction (MTJ) devices whose ultra-thin aluminum oxide tunnel barrier was irradiated by highly charged ions (HCIs) increases linearly with the fluence of HCIs, while retaining a current-voltage relationship

Identity Management and Privacy: A Rare Opportunity To Get It Right

June 1, 2011
Author(s)
Ari M. Schwartz
Since 1976, when Whitfield Diffie and Martin Helleman, first surmised the possibilities for the potential uses for digital signatures in an IEEE publication, there has been ongoing discussion of building an online identity management structure. As use of

INDENTATION AND ADHESION AT SMALL LENGTH SCALES

June 1, 2011
Author(s)
Robert F. Cook
Indentation and adhesion are considered in the context of the two experimental methods predominantly used to measure contact behavior at small length scales, instrumented indentation testing and atomic force microscopy. The typical loads and displacements

Large Scale Fire Dynamics in Spacecraft in Reduced Gravity

June 1, 2011
Author(s)
Gregory T. Linteris
Numerical fire codes are being widely used for understanding normal gravity fires. The goal of the present project was to modify one such code, the National Institute of Standards and Technology Fire Dynamics Simulator, so that it can be used to accurately

Linear Dispersion Codes for Asynchronous Cooperative MIMO Systems

June 1, 2011
Author(s)
Hamid Gharavi
In this treatise, we propose a novel family of Asynchronous Cooperative Linear Dispersion Codes (ACLDCs), which is capable of maintaining full diversity in cooperative scenarios even at the presence of asynchronous reception. The linear dispersion

Mathematical Modeling of Wildland-Urban Interface Fires

June 1, 2011
Author(s)
Randall J. McDermott, Ronald Rehm
This paper presents a simple model to demonstrate the effect on grass-fire propagation of the winds induced by structural fires in a Wildland-Urban Interface (WUI) setting. The model combines an empirical formula for wind-driven grass-fire spread and a

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
