Operation Tomodachi -Fire Research Special Issue

July 1, 2016
Author(s)
Samuel Manzello, Sayaka Suzuki
NIST's Engineering Laboratory (EL-NIST) hosted "Operation Tomodachi - Fire Research" on March 16-18, 2015 in Gaithersburg, MD USA. Tomodachi means friendship in Japanese. This workshop was organized by Dr. Samuel L. Manzello of EL-NIST in partnership with

Perfluorinated Alkyl Acids in the Plasma of South African Crocodiles (Crocodylus niloticus)

July 1, 2016
Author(s)
Jessica Reiner, John Bowden, Ian Christie, Matthew P. Guillette, Theresa M. Cantu, Russell H. Lowers, Hannes Botha, Wilmien Luus-Powell, Willem J. Smit, Danny Govender, Danie Pienaar, Louis J. Guillette Jr.
Perfluorinated alkyl acids (PFAAs) are environmental contaminants that have been used in many products for over 50 years. Interest and concern has grown since 2000 on the widespread presence of PFAAs, when it was discovered that PFAAs were present in

Recent Activities of the National Commission on Forensic Science

July 1, 2016
Author(s)
John Butler
In February 2013, the U.S. Department of Justice (DOJ) and the National Institute of Standards and Technology (NIST) announced a partnership that included formation of the National Commission on Forensic Science (NCFS) and what is now the Organization of

Stabilizing Lithium and Sodium Fast-Ion Conduction in Solid Polyhedral-Borate Salts at Device-Relevant Temperatures

July 1, 2016
Author(s)
Wan Si NMN Tang, Motoaki Matsuo, Hui Wu, Vitalie Stavila, Atsushi Unemoto, Shin-Ichi Orimo, Terrence J. Udovic
Mechanically milling a variety of lithium and sodium closo-borate compounds enables the room-temperature stabilization of their fast-ion-conducting, high-T-like disordered phases. This represents a viable strategy for better exploiting the impressive

Technical Data Packages (TDPs) from the Smart Manufacturing Systems (SMS) Test Bed

July 1, 2016
Author(s)
Thomas D. Hedberg, Moneer M. Helu, Allison Barnard Feeney
Data is collected from the Manufacturing Lab using the MTConnect standard. That data is aggregated and published internally and externally of NIST via web services. Three channels of data dissemination are available or becoming available from the SMS Test

TRECVid Semantic Indexing of Video: A 6-Year Retrospective

July 1, 2016
Author(s)
George M. Awad, Cees Snoek, Alan Smeaton, Georges Quenot
Semantic indexing, or assigning semantic tags to video samples, is a key component for content-based access to video documents and collections. The Semantic Indexing task has been run at TRECVid from 2010 to 2015 with the support of NIST and the Quaero

Uncertainties in Nanometer-Scale Dimensional Metrology

July 1, 2016
Author(s)
John S. Villarrubia
These are slides used for an oral presentation made at the NIST "Workshop on Quantification of Uncertainties in Material Science." In nanometer-scale dimensional metrology, correction of probing errors, which are caused by the characteristic left/right

Attractive Interactions between DNA-Carbon Nanotube hybrids in Monovalent Salts

June 30, 2016
Author(s)
Ming Zheng, Xiangyun Qiu, Fuyou Ke, Raju Timsina, Constantine Y. Khripin
DNA-carbon nanotube (DNA-CNT) hybrids are nanometer-sized, highly-charged, rod-like molecules with complex surface chemistry, and their behaviors in aqueous solutions are governed by multifactorial interactions with both solvent and co-solutes. We have

Crystal Plasticity Analysis of Constitutive Behavior of 5754 Aluminum Sheet

June 30, 2016
Author(s)
Minh-Son Pham, Anthony D. Rollett, Adam Abel Creuziger, Mark Iadicola, Timothy J. Foecke
Crystal plasticity constitutive equations for the multi-axial stress-strain behavior of aluminum alloy 5754 sheets have been developed. A Taylor model, a self-consistent visco-plastic model and an N-site model based on the Fast Fourier Transform were used

Fast Dynamic Programming for Elastic Registration of Curves

June 30, 2016
Author(s)
Javier Bernal, Gunay Dogan, Robert Hagwood
Curve registration problems in data analysis and com- puter vision can often be reduced to the problem of match- ing two functions defined on an interval. Dynamic Pro- gramming (DP) is an effective approach to solve this prob- lem. In this paper, we

Identifying uncertainty in Laser Powder Bed Fusion models

June 30, 2016
Author(s)
Felipe F. Lopez, Paul Witherell, Brandon Lane
A limitation frequently encountered in additive manufacturing (AM) models is a lack of indication about their precision and accuracy. Often overlooked, information on model uncertainty is required for validation of AM models, qualification of AM-produced
