Inferring Intention Through State Representations in Cooperative Human-Robot Environments

June 7, 2013
Author(s)
Craig I. Schlenoff, Anthony Pietromartire, Zeid Kootbally, Stephen B. Balakirsky, Thomas R. Kramer, Sebti Foufou
In this paper, we describe a novel approach for inferring intention during cooperative human-robot activities through the representation and ordering of state information. State relationships are represented by a combination of spatial relationships in a

Laser-Machined Ultra-High-Q Microrod Resonators for Nonlinear Optics

June 7, 2013
Author(s)
Pascal P. Del'Haye, Scott B. Papp, Scott A. Diddams
Optical whispering-gallery microresonators are useful tools in microphotonics, and non-linear optics at very low threshold powers. Here, we present details about the fabrication of ultra-high-Q whispering-gallery-mode (WGM) resonators made by CO2-laser

The Impact of Characteristic Impedance on Waveform Calibrations

June 7, 2013
Author(s)
Dylan F. Williams, Jeffrey A. Jargon, Paul D. Hale
We examine the impact of the characteristic impedance on mismatch corrections for temporal waveform calibrations based on high-speed electro-optic sampling measurements. We show that failing to measure and account for the characteristic impedance of

We examine the impact of the characteristic impedance on mismatch corrections for temporal waveform calibrations based on high-speed electro-optic sampling measurements. We show that failing to measure and account for the characteristic impedance of

A Precision Millimeter-Wave Modulated-Signal Source

June 6, 2013
Author(s)
Catherine A. Remley, Paul D. Hale, Dylan F. Williams, Chih-Ming Wang
We develop and characterize a modulated-signal source for use at millimeter-wave frequencies. Components within the source are phase locked by a 10 GHz reference source to minimize drift and improve synchronization. The complex frequency response of the

SHREC13 Track: Large Scale Sketch-Based 3D Shape Retrieval

June 6, 2013
Author(s)
Afzal A. Godil, Bo Li , Yijuan Lu, Tobias Schreck
Sketch-based 3D shape retrieval has become an important research topic in content-based 3D object retrieval. The aim of this track is to measure and compare the performance of sketch-based 3D shape retrieval methods based on a large scale hand-drawn sketch

A Case Study of a Community Affected by the Witch and Guejito Fires: Report #2 Evaluating the Effects of Hazard Mitigation Actions on Structure Ignitions

June 5, 2013
Author(s)
Alexander Maranghides, Derek McNamara, William Mell, Jason Trook, Blaza Toman
The National Institute of Standards and Technology (NIST) has a suite of research projects addressing risk reduction in Wildland Urban Interface (WUI) communities. The NIST WUI Team was invited by CAL FIRE to collect post incident data from the California

Development of a Methodology to Determine Risk of Counterfeit Use

June 5, 2013
Author(s)
Mark Schaffer, Yaw S. Obeng
Counterfeit components have become a multi-million dollar, yet undesirable, part of the electronics industry. The profitability of the counterfeit industry rests in large part on its ability to recognize supply constraints and quickly respond, effectively

Glossary of Key Information Security Terms

June 5, 2013
Author(s)
Richard L. Kissel
The National Institute of Standards and Technology (NIST) has received numerous requests to provide a summary glossary for our publications and other relevant sources, and to make the glossary available to practitioners. As a result of these requests, this

Metrics and Test Methods for Industrial Kit Building

June 5, 2013
Author(s)
Stephen B. Balakirsky, Thomas R. Kramer, Zeid Kootbally, Anthony Pietromartire
The IEEE RAS Ontologies for Robotics and Automation Working Group is dedicated to developing a methodology for knowledge representation and reasoning in robotics and automation. As part of this working group, the Industrial Robots sub-group is tasked with

Transition Energies of the D-lines in Na-like Ions

June 5, 2013
Author(s)
John D. Gillaspy, Dmitry D. Osin, Yuri Ralchenko, Joseph Reader, S A. Blundell
The NIST electron beam ion trap (EBIT) was used to measure the D1 (3s-3p1/2) and D2 (3s-3p3/2) transitions in Na-like ions of xenon, barium, samarium, gadolinium, dysprosium, erbium, tungsten, platinum, and bismuth. New relativistic many-body perturbation

A Generative Model for Fingerprint Minutiae

June 4, 2013
Author(s)
Melissa K. Taylor, Nicholas G. Paulter Jr., Qijun Zhao, Yi Zhang, Anil K. Jain
Fingerprint minutiae are the most important features used by latent fingerprint examiners, as well as in automated fingerprint recognition systems. Hence, understanding the statistical distribution of minutiae is essential in many fingerprint recognition

A REFERENCE MEASUREMENT SYSTEM FOR ELECTROSHOCK WEAPONS

June 3, 2013
Author(s)
Nicholas G. Paulter Jr., Donald R. Larson
We have developed a measurement system to accurately measure the electrical current and high-voltage output of electroshock weapons (ESW) that are used to deliver an electrical stimulus to humans for the purpose of incapacitation. Since the output of

Dynamic Response of Metals Subject to Rapid DC Current Pulses

June 3, 2013
Author(s)
Steven P. Mates, Graham Cullen, Eran Vax, Eli Marcus, Brad Kinsey
Recent investigations indicate that metals will deform plastically at much lower stress levels when subject to high density DC currents due to an influence of electrical current on dislocation motion that is athermal in nature. Practical applications in

Effect of Organic SAMs on the Evolution of Strength of Silicon Nanostructures

June 3, 2013
Author(s)
Scott Grutzik, Brian G. Bush, Frank W. DelRio, Richard S. Gates, Melissa Hines, Alan Zehnder
The ability to accurately predict the strength of nanoscale, single crystal structures is critical in micro- and nano-electromechanical systems (MEMS and NEMS) design. Because of the small length scales involved failure does not always follow the same
