Viscoelastic Property Mapping with Contact Resonance Force Microscopy

November 4, 2011
Author(s)
Jason P. Killgore, Donna C. Hurley, Dalia Yablon, Joseph Turner, Philip Yuya, Roger Proksch, Anil Gannepalli, Andy Tsou
We demonstrate accurate nanoscale mapping of loss and storage modulus on a polystyrene-polypropylene blend with contact resonance force microscopy (CR-FM). The viscoelastic properties are extracted from spatially resolved maps of the contact resonance

An Efficient Target Monitoring Scheme with Controlled Node Mobility for Sensor Networks

November 3, 2011
Author(s)
Vladimir V. Marbukh, Kamran Sayrafian, Hamid Mahboubi, Ahmadreza Momeni, Amir G. Aghdam
This paper is concerned with target monitoring using a network of collaborative mobile sensors. The objective is to compute (online) the desired sensing and communication radii of sensors as well as their location at each time instant, such that a set of

Data Dependency on Measurement Uncertainties in Speaker Recognition Evaluation

November 3, 2011
Author(s)
Jin Chu Wu, Alvin F. Martin, Craig S. Greenberg, Raghu N. Kacker
The National Institute of Standards and Technology (NIST) has been conducting an ongoing series of Speaker Recognition Evaluations (SRE). Speaker detection performance is measured using a detection cost function defined as a weighted sum of the

An Information Model Standard for Facility Integration With A Smart Grid

November 1, 2011
Author(s)
Steven T. Bushby
The National Electrical Manufacturer's Association (NEMA) and the American Society of Heating Refrigerating, and Air-Conditioning Engineers (ASHRAE) are working to cooperatively develop a national Facility Smart Grid Information Model standard. This

Annual Report of the National Earthquake Hazards Reduction Program for Fiscal Year 2010

November 1, 2011
Author(s)
John(Jack) R. Hayes Jr., Steven L. McCabe, Edward Laatsch, Joy Pauschke, David Applegate, John Filson, Tina M. Faecke
This annual report of the National Earthquake Hazards Reduction Program (NEHRP) for fiscal year 2010 is submitted to Congress by the Interagency Coordinating Committee (ICC) of NEHRP, as required by the Earthquake Hazards Reduction Program Reauthorization

Common-Arm Counter-Propagating Interferometer for Fiber Vibration Measurements

November 1, 2011
Author(s)
Craig W. Nelson, Archita Hati, David A. Howe
We propose and demonstrate a novel technique to measure the vibration sensitivity of two-port fiber-based optical components. It uses a common-arm counter-propagating frequency-shifted interferometer that cancels the vibration induced phase noise of the

Discovery of giant magnetostriction in annealed Co1-xFex thin-films

November 1, 2011
Author(s)
Dwight Hunter, William Alexander Osborn, Ke Wang, Nataliya Kazantseva, Jason Hattrick-Simpers, Richard Suchoski, Ryota Takahashi, Marcus L. Young, Apurva Mehta, Leonid A. Bendersky, Sam E. Lofland, Manfred Wuttig, Ichiro Takeuchi
Chemical and structural heterogeneity and resulting interaction of coexisting phases can lead to extraordinary behaviors in oxides as observed in piezoelectric materials at morphotropic phase boundaries and relaxor ferroelectrics. But such phenomena are

Effect of Neutron Irradiation on Dosimetric Properties of the TLD-600H (Lif6:Mg,Cu,P)

November 1, 2011
Author(s)
Alexander A. Romanyukha, Ronaldo Minniti, M. Moscovitch, Alan Keith Thompson, F. Trompier, Ronald Colle, A Sucheta, S. P. Voss, L. A. Benevides
Ideally, dosimeters should measure the dose without their dosimetric properties being affected by the radiation type being measured. Industry-wide occupational radiation workers that can be potentially exposed to neutron radiation fields are routinely

Findings and Recommendations from the Joint NIST AGA Workshop on Odor Masking

November 1, 2011
Author(s)
Thomas J. Bruno, Nancy Rawson, Ali Quaraishi
Since the days of the alchemist, the observation that some substances have a smell while other substances do not has been a source of fascination. The sense of smell, or olfaction, is our least understood sense, however it is important for many human

Home Cooking Fire Mitigation: Technology Assessment. Final Report.

November 1, 2011
Author(s)
Joshua Dinaburg, Daniel T. Guttuk
Cooking related fires are a leading cause of U.S. fire loss. Beginning in the mid 1980's, the National Institute of Standards and Technology, Consumer Product Safety Commission, and the home appliance industry undertook a comprehensive review 1 of

Local Weak Ferromagnetism in Single-Crystalline Ferroelectric BiFeO 3

November 1, 2011
Author(s)
M. Ramazanoglu, M. Laver, William D. Ratcliff, Shannon M. Watson, Wangchun Chen, Andrew Jackson, Karunakar NMN Kothapalli, Seongsu Lee, S.- W. Cheong, V. Kiryukhin
Polarized small-angle neutron scattering studies of single-crystalline multiferroic BefeO 3 reveal a long-wavelength spin density wave generated by 1° spin canting of the spins out of the rotation plane of the antiferromagnetic cycloidal order. This
