Coordinate Metrology and the Proposed E57.02 Static Pose Determination Standard

March 29, 2013
Author(s)
David MacKinnon, J.-Angelo Beraldin, Tsai H. Hong, Jeremy Marvel
We present the Proposed Standard ASTM E57.02 "Standard Test Method for Evaluating Static Pose Measurement Systems" (Work Item ASTM WK31638) and explain why it should be considered important by coordinate metrologists. The stated purpose of the standard is

Ground Truth Systems for Object Recognition and Tracking

March 29, 2013
Author(s)
Afzal A. Godil, Roger D. Eastman, Tsai H. Hong
In this report we discuss different types of ground-truth systems used for evaluation of object recognition and tracking systems in industrial manufacturing environments. We discuss three main ways for acquiring ground truth for object recognition and

Explosive Standards Forum Recommendations

March 28, 2013
Author(s)
William G. Billotte, Sharon B. Nakich
From September 2011 to September 2012, the NIST Law Enforcement Standards Office (OLES), sponsored by the U.S. Department of Homeland Security Science and Technology Directorate (DHS S&T), collected recommendations for the adoption and/or development of

Paving the Way for a More Sustainable Concrete Infrastructure: A Vision for Developing a Comprehensive Description of Cement Hydration Kinetics

March 28, 2013
Author(s)
Joseph J. Biernacki, Jeffrey W. Bullard, Constantiner Constantiner, Richard Meininger, Maria Juenger, Josephine H. Cheung, William Hansen, R. D. Hooton, Andreas Luttge, Jeffrey J. Thomas
Hydration of portland cement is the cornerstone of the process responsible for microstructure development in concrete and ultimately controls the kinetics of all materials properties that make concrete such a useful product for society (properties such as

Correlation for the Viscosity of Hydrogen obtained from Symbolic Regression

March 27, 2013
Author(s)
Chris D. Muzny, Marcia L. Huber, Andrei F. Kazakov
We report the results of a symbolic regression methodology to obtain both the functional form and the coefficients for a wide-ranging correlation for the viscosity of normal hydrogen. The correlation covers the temperature range from the triple point

Evaluation of Pacific White Shrimp (Litopenaeus vannamei) Health During a Superintensive Aquaculture Growout using NMR-based Metabolomics

March 27, 2013
Author(s)
Tracey B. Schock, Dan Bearden, Jessica Duke, Abby Goodson, Daryl Weldon, Jeff Brunson, John Leffler
Success of the shrimp aquaculture industry requires technological advances that increase production and environmental sustainability. Indoor, superintensive, aquaculture systems have been developed that permit year-round production of farmed shrimp at high

Graphene as Transparent Electrode for Direct Observation of Hole Photoemission from Silicon to Oxide

March 27, 2013
Author(s)
Rusen Yan, Qin Zhang, Oleg A. Kirillov, Wei Li, James I. Basham, Alexander G. Boosalis, Xuelei X. Liang, Debdeep Jena, Curt A. Richter, Alan C. Seabaugh, David J. Gundlach, Huili G. Xing, Nhan V. Nguyen
The outstanding electrical and optical properties of graphene make it an excellent alternative as a transparent electrode. Here we demonstrate the application of graphene as collector material in internal photoemission (IPE) spectroscopy; enabling the

Interfacial Reaction of Co-Fe Films with SiO_{2} Substrates

March 27, 2013
Author(s)
Leonid A. Bendersky, N. V. Kazantseva, Ursula R. Kattner, M K. Kang, Vladimir P. Oleshko, Dwight Hunter, Ichiro Takeuchi
The interdiffusion reaction between Co(1-x)Fex deposited films of various compositions (x = 0.27, 0.32 and 0.50) and an amorphous SiO2 substrate during annealing in vacuum at 800o C was identified by analytical transmission electron microscopy. The

The MEMS 5-in-1 Test Chips (Reference Materials 8096 and 8097)

March 27, 2013
Author(s)
Janet M. Cassard, Jon C. Geist, Craig D. McGray, Richard A. Allen, Muhammad Y. Afridi, Brian J. Nablo, Michael Gaitan, David G. Seiler
This paper presents an overview of the Microelectromechanical Systems (MEMS) 5-in-1 Reference Material (RM), which is a single test chip with test structures from which material and dimensional properties are obtained using five documentary standard test

Analyzing Surfactant Structures on Length and Chirality Resolved (6,5) Single-Wall Carbon Nanotubes by Analytical Ultracentrifugation

March 26, 2013
Author(s)
Jeffrey A. Fagan, Ming Zheng, Jeffrey R. Simpson, Vinayak Rastogi, Constantine Y. Khripin, Carlos A. Silvera Batista, Angela R. Hight Walker
The structure and density of the bound interfacial surfactant layer and associated hydration shell were investigated using analytical ultracentrifugation for length and chirality purified (6,5) single-wall carbon nanotubes (SWCNTs) in three different bile

Camera Recognition

March 26, 2013
Author(s)
Michelle P. Steves, Brian C. Stanton, Mary F. Theofanos, Dana E. Chisnell, Hannah Wald
The Department of Homeland Security’s (DHS) United States Visitor and Immigrant Status Indicator Technology (US-VISIT) program is a biometrically-enhanced identification system primarily situated at border points of entry such as airports and seaports. In
