Interlaboratory Study of Alternate Filter Papers for Use in ASTM E 2187

December 11, 2009
Author(s)
Richard G. Gann, William F. Guthrie
ASTM E 2187 has become the internationally referenced standard for designing and specifying less fire-prone cigarettes. In this test method, a lit cigarette is laid on multiple layers of filter paper, and the observer identifies whether the cigarette burns

MEMS Parallel Plate Rheometer for Oscillatory Shear Micro Rheology Measurements

December 11, 2009
Author(s)
Gordon Christopher, Nicholas G. Dagalakis, Steven D. Hudson, Kalman D. Migler
Growing numbers of applications including proteomics, cosmetics, and thin film coatings use novel viscoelastic materials that derive their rheological properties from micro scale structure created by the inclusion of long chain molecules, nano particles

Compensation of Field-Induced Frequency Shifts in Ramsey Spectroscopy of Optical Clock Transitions

December 10, 2009
Author(s)
A. V. Taichenachev, V. I. Yudin, Christopher W. Oates, Barber W. Zeb, Nathan D. Lemke, Andrew Ludlow, U Sterr, Ch. Lisdat, F Reihle
We develop a modified version of Ramsey spectroscopy that uses an additional frequency shift to compensate frequency shifts induced by the excitation itself. In its simplest realization, this method uses a small step of the probe frequency during the two

Oersted Field Induced Magnetization Scissoring In Permalloy Bars

December 10, 2009
Author(s)
Lu Yuan, Fabio C. da Silva, Sean Halloran, Hamid Z. Fardi, David P. Pappas
We have systematically studied the magnetization behavior induced by the applied current in the permalloy (Ni81Fe19) bars using second and third harmonic analysis. Three types of sample were studied with layer structures of Al30/NiFe10, NiFe5/Al30/NiFe5

CT Assessment of Response to Therapy: Tumor Volume Change Measurement, Truth Data & Error

December 9, 2009
Author(s)
Charles D. Fenimore, Michael McNitt-Gray, Luc Bidaut, Samuel G. Armato, Charles R. Meyer, Marios A. Gavrielides, Geoffrey McLennan, Nicholas Petrick, Binsheng Zhao, Anthony P. Reeves, Reinhard R. Beichel, Grace Kim
Rationale and Objectives: This manuscript describes issues and methods that are specific to the measurement of change in tumor volume as measured from CT images and how these would relate to the establishment of CT tumor volumetrics as a biomarker of

Evaluation of the state-of-the-art measurement capabilities for selected PBDEs and decaBB in plastic by the international intercomparison CCQM-P114

December 9, 2009
Author(s)
Michele M. Schantz, Katrice A. Lippa, R. Zeleny, S. Voorspoels, M. Ricci, Dorit Becker, M. Sittidech, A.M.F. Wong, D.H. Kim, S. Mingwu, S. Matsuyama
An international intercomparison involving eight National Metrology Institutes (NMIs) was conducted to establish their current measurement capabilities for determining five selected congeners from the brominated flame retardant classes polybrominated

Organohalogen contaminants in blood of Kemp's ridley (Lepidochelys kempii) and green sea turtles (Chelonia mydas) from the Gulf of Mexico

December 9, 2009
Author(s)
Robert R. Swarthout, Jennifer Lynch, Margie Peden-Adams, Andre Landry, Patricia Fair, John Kucklick
The threat that exposure to organohalogen (OH) contaminants poses to endangered populations of Kemp's ridley (Lepidochelys kempii) and green sea turtles (Chelonia mydas) is not well understood, partly because few OH data are available. Blood samples from

Proceedings of the GSA 3D Imaging Workshop, February 28, 2011 (NIST TN 1699)

December 9, 2009
Author(s)
Geraldine S. Cheok, Marek Franaszek, Kamel S. Saidi
The General Services Administration (GSA) has been involved in 3D imaging since the early 2000s. Since 3D imaging was a relatively new technology at that time, GSA needed to develop and provide initial guidance to their project managers (PMs) on 3D imaging

Text Retrieval Conference (TREC)

December 9, 2009
Author(s)
Ellen M. Voorhees
This article summarizes the history, results, and impact of the Text Retrieval Conference (TREC), a workshop series designed to support the information retrieval community by building the infrastructure necessary for large-scale evaluation of retrieval

The effect of strain on grains and grain boundaries in YBa2Cu3O7-d coated conductors

December 9, 2009
Author(s)
Daniel C. van der Laan, John (Jack) W. Ekin, Timothy J. Haugan, Paul N. Barnes, Dmytro Abraimov, Fumitake Kametani, David C. Larbalestier, Marty Rupich
The role of grains and grain boundaries in producing reversible strain effects on the transport current critical current (Ic) of YBa2Cu3O7-δ coated conductors was investigated by comparing the strain ε dependence of full-width coated conductors with that

The TRECVid 2008 Event Detection Evaluation

December 9, 2009
Author(s)
Jonathan G. Fiscus, John S. Garofolo, Paul D. Over, Martial Michel, Richard T. Rose
This paper is a summary of the 2008 TRECVid Event Detection evaluation. TRECVid is a laboratory-style evaluation that aims to model real world situations or significant component tasks. The event detection evaluation was organized to address detection of a

An Automated Ionization Chamber for Secondary Radioactivity Standards

December 8, 2009
Author(s)
Ryan P. Fitzgerald
We report on the operation and characterization of a new ionization chamber system, called AUTOIC, featuring a commerical digital electrometer and a commerical robotic sample changer. The ralative accuracy of the electrometer was improved significantly

Experimental Verification of Z Antennas at UHF Frequencies

December 8, 2009
Author(s)
Christopher L. Holloway, Richard Ziolkowski, Peng Jin, J. A. Nielsen, M. H. Tanielian
Both 300 MHz and 570 MHz versions of the electrically small coaxially-fed Z antenna were designed and tested. These two cases demonstrate the ability to change the resonance frequency of the Z antenna by changing the value of its lumped element inductor
