OOF3D: An Image-Based Finite Element Solver for Materials Science

March 28, 2012
Author(s)
Valerie R. Coffman, Andrew C. Reid, Stephen A. Langer, Gunay Dogan
Recent advances in experimental techniques (micro CT scans, automated serial sectioning, electron back-scatter diffraction, synchrotron radiation x-rays) have made it possible to characterize the full, three dimensional structure of real materials. Such

Comment on "Magnetic Structure of Gd 2 Ti 2 O^d7"

March 27, 2012
Author(s)
J. R. Stewart, G. Ehlers, A. S. Wills, S.T. Bramwell, Jason S. Gardner
M. W. Long and collaborators [Phys. Rev. B, 83 054422 (2011)] recently proposed solutions to the magnetic structure of gadolinium titanate that differ to those previously reported bu us [J. R. Stewart, G. Ehlers, A. S. Wills, S. T. Bramwell and J. S

A Matter of Policy

March 26, 2012
Author(s)
David F. Ferraiolo, Jeffrey M. Voas, George Hurlburt
This paper discusses system security policies. System policies are the set of rules that when implemented afford a strategy for the protection of information. The policy objectives are diverse and span the social-economic spectrum. System policies govern

Time-Resolved Infrared Spectroscopy of an [FeFe]-Hydrogenase Model Compound

March 26, 2012
Author(s)
Edwin J. Heilweil
Naturally occurring hydrogenases catalyze the reaction of H+ to form H2 gas. To develop a hydrogen source that is not reliant on fossil fuels, synthetic [FeFe]-hydrogenase model species are being studied. These compounds have a wing-like structure with a

In Situ Raman Monitoring of Ring-Opening Copolymerizations

March 25, 2012
Author(s)
Matthew T. Hunley, Santanu S. Kundu, Peter M. Johnson, Kathryn Beers
Recent advances in enzyme, metal, and organic catalysts have enabled the development of advanced functional polymers from cyclic ester and cyclic carbonate monomers. In this work, we present an in situ technique to monitor ring-opening polymerization using

Flexible polyurethane foam with well characterized and reproducible smoldering

March 24, 2012
Author(s)
Mauro Zammarano, Szabolcs Matko, Rick D. Davis, Roland H. Kraemer
Smoldering is a self-sustaining heterogeneous oxidation reaction that induces a slow, low temperature, flameless combustion.1 Flexible polyurethane foams (PUF) are particularly prone to smoldering due to their high air permeability and low density. In this

Modeling the effects of acid amplifiers on photoresist stochastics

March 23, 2012
Author(s)
Gregg M. Gallatin, Patrick Naulleau, Robert Brainard
The tradeoff between Resolution, Line Edge Roughness (LER) and Sensitivity, the so called RLS tradeoff, continues to be a difficult challenge, especially for EUV lithography. Acid amplifiers have recently been proposed as a method to improve upon the

2011 Solutions in Perception Challenge Performance Metrics and Results

March 22, 2012
Author(s)
Jeremy Marvel, Tsai H. Hong, Elena R. Messina
The 2011 Solutions in Perception Challenge (SPC) presented an international collection of teams with the opportunity to develop algorithms that could positively identify and accurately locate in space an arbitrary collection of artifacts. Researchers at

A Keyed Sponge Construction with Pseudorandomness in the Standard Model

March 22, 2012
Author(s)
Donghoon Chang, Morris Dworkin, Seokhie Hong, John M. Kelsey, Mridul Nandi
The sponge construction, designed by Bertoni, Daemen, Peeters, and Asscheis, is the framework for hash functions such as Keccak, PHOTON, Quark, and spongent. The designers give a keyed sponge construction by prepending the message with key and prove a

An IEEE 1588 Performance Testing Dashboard for Power Industry Requirements

March 22, 2012
Author(s)
Julien M. Amelot, YaShian Li-Baboud, Clement Vasseur, Jeffrey Fletcher, Dhananjay Anand, James Moyne
The numerous time synchronization performance requirements in the Smart Grid entails the need for a set of common metrics and test methods to verify the ability of the network system and its components to meet the power industry�s accuracy, reliability and

Development of Ballistics Identification - From Image Comparison to Topography Measurement in Surface Metrology-

March 22, 2012
Author(s)
Jun-Feng Song, Theodore V. Vorburger, Robert M. Thompson, Thomas Brian Renegar, Xiaoyu Alan Zheng, James H. Yen, Richard M. Silver, Wei Chu
Fired bullets and ejected cartridge cases have unique ballistics signatures left by the firearm. By analyzing the ballistics signatures, forensic examiners can trace these bullets and cartridge cases to the firearm used in a crime scene. Current automated

Emergency Response Robot Evaluation Exercise

March 22, 2012
Author(s)
Adam S. Jacoff, Hui-Min Huang, Ann Virts, Anthony Downs, Raymond Sheh
More than 60 robot test methods are being developed by a team lead by the National Institute of Standards and Technology (NIST) with the sponsorship of U.S. Department of Homeland Security (DHS). These test methods are being specified and standardized

Functional Requirements of a Model for Kitting Plans

March 22, 2012
Author(s)
Stephen B. Balakirsky, Zeid Kootbally, Thomas R. Kramer, Rajmohan Madhavan, Craig I. Schlenoff, Michael O. Shneier
Industrial assembly of manufactured products is often performed by first bringing parts together in a kit and then moving the kit to the assembly area where the parts are used to assemble products. Kitting, the process of building kits, has not yet been
