Instrument Interface Standards for Interoperable Ocean Sensor Networks

May 11, 2009
Author(s)
Kang B. Lee, Yuyin Song, Thomas O'Reilly, K. Headley, D. Edgington, C. Rueda, J. Zedlitz , J. Del Rio, E. Delory, S. Fairgrieve, L. Bermudez
The utility and cost-effectiveness of large scale instrument networks are enhanced by instrument interoperability. Today s oceanographic instruments are characterized by very diverse non-standard software protocols and data formats. This diversity of

Measurement of Small Birefringence and Loss in a Nonlinear Single-mode Waveguide

May 11, 2009
Author(s)
Daniel Rogers, Charles W. Clark, Christopher Richardson, Julius Goldhar
We design and fabricate a birefringent semiconductor waveguide for application to nonlinear photonics, demonstrating that it is possible to engineer a small birefringence into such a device using multiple core layers. We also demonstrate a simple technique

PARAMETER VALIDATION USING CONSTRAINT OPTIMIZATION FOR MODELING AND SIMULATION

May 11, 2009
Author(s)
Guodong Shao, Charles R. McLean, Alexander Brodsky, Paul Ammann
Modeling and simulation (M&S) techniques are increasingly being used to solve problems and aid decision making in many different fields. Results of simulations are expected to provide reliable information for decision makers. But potential errors may be

The Origin of Critical Relative Humidity in Adhesion

May 11, 2009
Author(s)
Christopher C. White, Kar T. Tan, Bryan D. Vogt, Donald L. Hunston
Water is ubiquitous in the atmosphere. Unfortunately, adhesive bonding is susceptible to the environmental attack of water leading to significant depreciation in joint strength and subsequently to premature failures [1-6]. This susceptibility of bonding to

Super-hydrophobic and/or Super-hydrophilic Surfaces Made by Plasma Process

May 8, 2009
Author(s)
Lei Chen, Gerard Henein, James A. Liddle
In this paper, a simple, fast, all-plasma surface modification (APSM) process, which can form super-hydrophobic and/or super-hydrophilic surfaces is introduced. The APSM process includes plasma-induced surface nano-pattern formation, substrate etching and

Ultraviolet degradation study of photomultiplier tubes at SURF III

May 8, 2009
Author(s)
Ping-Shine Shaw, Lindsay Hum, Zhigang Li, Keith R. Lykke, Michael Bishop
Photomultiplier tubes (PMTs) are used in biological detection systems in order to detect the presence of biological warfare agents. To ensure proper operation of these biological detection systems, the performance of PMTs must be characterized in terms of

A High-throughput Screening System for Thermoelectric Material Exploration Based on Combinatorial Film Approach

May 7, 2009
Author(s)
Makoto Otani, Evan L. Thomas, Winnie Wong-Ng, Peter K. Schenck, Nathan Lowhorn, Martin L. Green, Hiroyuki Ohguchi
A high-throughput system that consists of a combinatorial tool (a sputtering deposition tool and a pulsed laser deposition tool) and two property screening devices, developed at NIST, was used for thermoelectric material exploration. The thermoelectric

PicoWatt Infrared Power Measurement using an Absolute Cryogenic Radiometer

May 7, 2009
Author(s)
Stephen Carr, Solomon I. Woods, Timothy M. Jung, Adriaan C. Carter, Raju V. Datla
We report on initial measurements of the low-temperature thermal properties of a device that is similar to the experimental apparatus used for absolute cryogenic radiometry (ACR) within the Low Background Infrared Radiometry (LBIR) facility at NIST. The

Sensor Alert Web Service for IEEE 1451-Based Sensor Networks

May 7, 2009
Author(s)
Kang B. Lee, Yuyin Song
This paper describes the Sensor Alert Web Service (SAWS) for the Institute of Electrical and Electronics Engineers (IEEE) 1451-based sensor networks developed at the National Institute of Standards and Technology (NIST). The SAWS consists of the Sensor

Mobile Device Forensics - Tool Testing

May 6, 2009
Author(s)
Richard Ayers
The goal of the Computer Forensic Tool Testing (CFTT) project at the National Institute of Standards and Technology (NIST) is to establish a methodology for testing computer forensic software tools. The results provide information necessary for toolmakers

Report of Findings: Use of Language in Ballot Instructions

May 6, 2009
Author(s)
Janice G. Redish, Dana Chisnell, Ethan Newby, Sharon J. Laskowski, Svetlana Z. Lowry
In this study, we compared two ballots that differed only in wording and presentation of the language on the ballots. For Ballot A, we used conventional wording and presentation, taken from typical ballots. For Ballot B, we used plain language wording and

Testing and Analysis of Steel Beam-Column Assemblies under Column Removal Scenarios

May 6, 2009
Author(s)
Fahim Sadek, Joseph A. Main, Hai S. Lew, Stephen D. Robert, Vincent Chiarito
This paper presents an experimental and analytical assessment of the performance of steel beam-column assemblies with two types of moment-resisting connections under vertical displacement of a center column, simulating a column removal scenario. The

Weighted Means Statistics in Interlaboratory Studies

May 6, 2009
Author(s)
Andrew L. Rukhin
The usefulness of weighted means statistics as a consensus mean estimator in collaborative studies is discussed. A random effects model designed to combine information from several sourcesis employed to justify their appeal to metrologists. Some methods of
