November 1, 2007
Author(s)
Steven W. Brown, S Flora, M Feinholz, M Yarbrough, Terrance Houlihan, D Peters, Yong S. Kim, J Mueller, Bettye C. Johnson, Dennis Clark
For the past decade, the Marine Optical Buoy (MOBY), an autonomous radiometric buoy stationed in the waters off Lanai, Hawaii, has been the primary in-water oceanic observatory for the vicarious calibration of U. S. satellite ocean color sensors, including

The role of metallurgy in the NIST investigation of the world trade center towers collapse

November 1, 2007
Author(s)
Stephen W. Banovic, Timothy J. Foecke, William E. Luecke, Joseph D. McColskey, Christopher N. McCowan, Thomas A. Siewert, Frank W. Gayle
On August 21, 2002, on the direction of the U.S. Congress, the National Institute of Standards and Technology (NIST) initiated an investigation into the collapse of the World Trade Center (WTC) towers. In support of the overall investigation goals, the

Time for a Better Receiver: Chip-Scale Atomic Frequency References

November 1, 2007
Author(s)
John E. Kitching
Atomic clocks and precision timing are at the core of almost every aspect of global navigation satellite systems (GNSS). A GNSS receiver determines its position with respect to a subset of the constellation of orbiting satellites by measuring the time

Young's Modulus Measurements in Standard IC CMOS Processes using MEMS Test Structures

November 1, 2007
Author(s)
Janet M. Cassard, David L. Herman, Paul T. Vernier, Don DeVoe, Michael Gaitan
This letter presents a method to measure the Young?s moduli of the individual thin film layers in a commercial integrated circuit (IC) foundry process. The method is based on measuring the resonance frequency of an array of micromachined cantilevers and

Development of Ultra-Low Magnetic Field Sensors With Magnetic Tunnel Junctions

October 31, 2007
Author(s)
Philip Pong, John E. Bonevich, William F. Egelhoff Jr.
The discovery of tunneling magnetoresistance (TMR) has enhanced the magnetoresistance (MR) ratio from the giant magnetoresistance (GMR) regime of around 10% to over 400% at room temperature. A combination of magnetic tunnel junctions with high

Investigating Resource Allocation in a Standards-Based Grid Compute Economy

October 31, 2007
Author(s)
Christopher E. Dabrowski
This paper reports work investigating resource allocation in a simulated grid compute economy where consumers and providers employ software components implemented with emerging WS and grid standards. The investigation employs a model to simulate inter

Critical Role of Side-Chain Attachment Density on the Order and Device Performance of Polythiophenes

October 30, 2007
Author(s)
Regis J. Kline, Dean DeLongchamp, Daniel A. Fischer, Eric K. Lin, Lee J. Richter, Michael L. Chabinyc, Martin Heeney, Iain McCulloch
High performance, solution processable semiconductors are critical to the realization of low cost, large area electronics. We show that a signature molecular packing motif - side-chain interdigitation - correlates to high performance for a large and

VAST 2007 Contest - Blue Iguanadon

October 30, 2007
Author(s)
Georges Grinstein, Catherine Plaisant, Theresa O'Connell, Sharon J. Laskowski, Jean Scholtz, Mark Whiting
Visual analytics experts realize that one effective way to push the field forward and to develop metrics for measuring the performance of various visual analytics components is to hold an annual competition. The second Visual Analytics Science and

Compositional Control in Electrodeposited Ni (subscript x) Pt (subscript 1-x) Films

October 29, 2007
Author(s)
J Mallett, Erik B. Svedberg, John E. Bonevich, Alexander J. Shapiro, William F. Egelhoff Jr., Thomas P. Moffat
Electrochemical co-deposition of a series of fcc Ni(subscript x)PT(subscript 1-x) alloys is demonstrated. The alloy composition is a monotonic function of potential. The Pt-rich Ni(subscript x)PT(subscript 1-x) alloys are formed at potentials positive to

Effect of Static Analysis Tools on Software Security: Preliminary Investigation

October 29, 2007
Author(s)
Vadim Okun, William F. Guthrie, Romain Gaucher, Paul E. Black
Static analysis tools can handle large-scale software and find thousands of defects. But do they improve software security? We evaluate the effect of static analysis tool use on software security in open source projects. We measure security by

Joseph C. Woicik, M A. Sahiner, Timothy Kurp, Jeffrey Serfass, Marc Aranguren
The continuous downward scaling of the complementary metal oxide semiconductor (CMOS) devices has enabled the Si-based semiconductor industry to meet the technological requirements such as high performance and low power consumption. However, the ever

Technical Variation in Modeling the Joint Expression of Several Genes

October 25, 2007
Author(s)
Walter S. Liggett Jr
Biological studies based on expression microarrays often depend crucially on comparison of expression measurements that are subject to technical variation associated with changes in time, laboratory or other measurement conditions. If a biological study

The Common Vulnerability Scoring System (CVSS)
