Ocular and Iris Recognition Baseline Algorithm

November 7, 2011
Author(s)
Yooyoung Lee, Ross J. Micheals, James J. Filliben, P J. Phillips, Hassan A. Sahibzada
Due to its distinctiveness, the human eye is a popular biometricv feature used to identity a person with high accuracy. The Grand Challenge in biometrics is to have an effective algorithm for subject verification or identification under a broad range of

On Non-Linear Estimation of a Measurand

November 7, 2011
Author(s)
Chih-Ming Wang, Hariharan K. Iyer
We consider an estimation problem described in the Guide to the Expression of Uncertainty in Measurement (GUM). The problem is concerned with estimating a measurand that is a non-linear function of input quantities. The GUM describes two methods for

Protein characterization of a candidate mechanism SNP for Crohn's disease: the macrophage stimulating protein R689C substitution

November 7, 2011
Author(s)
Illarion V. Turko, Natalia Gorlatova, Kinlin L. Chao, Lipika Ray, Rawan Araj, Andrey Galkin, John Moult, Osnat Herzberg
Macrophage Stimulating Protein (MSP) is the ligand of RON receptor tyrosine kinase. MSP binding to RON activates a signaling pathway that plays a dual role in inflammation, initially stimulating macrophage chemotaxis and phagocytosis, but also changing

Report on Residential Fireground Field Experiments

November 7, 2011
Author(s)
Jason D. Averill, Lori Moore-Merrell, Adam M. Barowy, Robert Santos, Richard D. Peacock, Kathy Notarianni, Doug Wissoker
Service expectations placed on the fire service, including Emergency Medical Services (EMS), response to natural disasters, hazardous materials incidents, and acts of terrorism, have steadily increased. However, local decision-makers are challenged to

Service Model Driven Variations in Security Measures for Cloud Environments

November 6, 2011
Author(s)
Ramaswamy Chandramouli
With the increasing adoption of cloud computing service models - Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS), proper implementation of adequate and appropriate security protection measures has become a

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

"Just Try"

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
