A public randomness service

July 21, 2011
Author(s)
Michael J. Fischer, Michaela Iorga, Rene Peralta
We argue for the deployment of sources of randomness on the Internet for promoting and enhancing electronic commerce. We describe, in rough detail, our planned implementation of such a source.

Diamagnetic correction to the 9 Be + ground-state hyperfine constant

July 21, 2011
Author(s)
Nobuyasu Shiga, Wayne M. Itano, John J. Bollinger
We report an experimental determination of the diamagnetic correction to the 9Be + ground state hyperfine constant A. We measured A = −625 008 837.371(11) Hz at a magnetic field B of 4.4609 T. Comparison with previous results, obtained at lower values of B

Gas Hydrate Research Database and Options for Data Exchange

July 21, 2011
Author(s)
Kenneth G. Kroenlein, Chris D. Muzny, Vladimir Diky, Robert D. Chirico, Michael D. Frenkel, E. D. Sloan
To facilitate advances in application of technologies pertaining to gas hydrates, a freely available data resource containing experimentally derived information about those materials was developed. This database is primary focused on thermophysical

IEEE RAS Standing Committee for Standards Activities: History and Status Update

July 21, 2011
Author(s)
Rajmohan Madhavan, Wonpil Yu, C Biggs, Craig I. Schlenoff, Hui-Min Huang
The Standing Committee for Standards Activities (SCSA) under the Industrial Activities Board (IAB) of the IEEE Robotics and Automation Society (RAS) is working together with the research and industrial communities and other Standards Developing

NIST Special Databse 32 - Multiple Encounter Dataset II (MEDS-II)

July 21, 2011
Author(s)
Andrew P. Founds, Nick Orlans, Whiddon Genevieve, Craig I. Watson
This document and associated dataset is an update to the Multiple Encounter Dataset I (MEDS-I), originally published by the National Institute of Standards and Technology (NIST) in May 2010. The MEDS is a test corpus organized from an extract of submission

Predicting Failure in Complex Systems by Perturbing Markov Chain Models

July 21, 2011
Author(s)
Christopher E. Dabrowski, Fern Y. Hunt
In recent years, substantial research has been devoted to monitoring and predicting performance degradations in real-world complex systems within large entities such as nuclear power plants, electrical grids, and distributed computing systems. Special

Structural Evidence for an Edge-Contaminated Vortex Phase in a Nb Crystal using Neutron Diffrraction

July 20, 2011
Author(s)
Helen A. Hanson, X. Wang, I. K. Dimitrov, J. Shi, X. S. Ling, Brian B. Maranville, Charles Majkrzak, M. Laver, U. Keiderling, M. Russina
We report the structural observation of a disordered vortex matter phase existing near the edge of a bulk type-II superconductor Nb using a novel position-sensitive neutron diffraction technique. This "edge-contaminated" vortex state was implicated in

Structure-property relationships for methyl-terminated alkyl self-assembled monolayers

July 20, 2011
Author(s)
Frank W. DelRio, Dave Rampulla, Cherno Jaye, Gheorghe Stan, Richard S. Gates, Daniel A. Fischer, Robert F. Cook
Structure-property relationships for methyl-terminated alkyl self-assembled monolayers (SAMs) are developed using near-edge X-ray absorption fine structure spectroscopy (NEXAFS) and atomic force microscopy (AFM). NEXAFS C K-edge spectra are used to compute

Timing in Telecommunications Networks

July 20, 2011
Author(s)
Judah Levine
I describe the statistical considerations used to design systems whose clocks are compared using dial-up telephone lines or the Internet to exchange timing informaiton. The comparison is usually used to synchronize the time of a client system to the time

Advanced Image Composition with Intra-Frame Drift Correction

July 19, 2011
Author(s)
Petr Cizmar, Andras Vladar, Michael T. Postek
Drift Corrected Image Composition (DCIC) is a real-time technique that allows for acquiring significantly more accurate images compare to traditional slow or fast imaging methods.[Ref.] It is especially useful in nanometer-scale imaging and metrology

Characterization of the non-uniform reaction in chemically-amplified calix[4]resorcinarene molecular resist thin films

July 19, 2011
Author(s)
Vivek M. Prabhu, Shuhui Kang, Regis J. Kline, Dean M. DeLongchamp, Daniel A. Fischer, Wen-Li Wu, Sushil K. Satija, Jing Sha, Christopher K. Ober, Peter V. Bonnesen
The ccc stereoisomer-purified tert-butoxycarbonyloxy (t-Boc) protected calix[4]resorcinarene molecular resists blended with photoacid generator exhibit a non-uniform photoacid catalyzed reaction in thin films. The surface displays a reduced reaction extent

Decision Support for Sustainable Manufacturing using Decision Guidance Query Language

July 19, 2011
Author(s)
Guodong Shao, Deogratias Kibira, Alexander Brodsky , Nathan Egge
Sustainability has become a very significant research topic as it impacts many different manufacturing industries. Therefore, the technologies for monitoring, analyzing, evaluating, and optimizing the sustainability performance indicators for manufacturing

Normal modes of trapped ions in the presence of anharmonic trap potentials

July 19, 2011
Author(s)
Jonathan Home, David Hanneke, John D. Jost, Dietrich Leibfried, David J. Wineland
We theoretically and experimentally examine the effects of anharmonic terms in the trapping potential for linear chains of trapped ions. We concentrate on two different effects, which become significant at different levels of anharmonicity. The first is a
