STEP File Analyzer Software

March 30, 2017
Author(s)
Robert R. Lipman
The STEP File Analyzer is a software tool that generates a spreadsheet or CSV files from a STEP (ISO 10303 –STandard for Exchange of Product model data) Part 21 file. STEP files are used to represent product and manufacturing information (PMI) and for data

Assessing the wavelength extensibility of optical patterned defect inspection

March 29, 2017
Author(s)
Bryan Barnes, Hui Zhou, Mark-Alexander Henn, Martin Sohn, Richard M. Silver
Qualitative comparisons have been made in the literature between the scattering off deep- subwavelength-sized defects and the scattering off spheres in free space to illustrate the challenges of optical defect inspection with decreasing patterning sizes

Evaluating the Effects of Modeling Errors for Isolated Finite3-D Targets

March 29, 2017
Author(s)
Mark-Alexander Henn, Bryan Barnes, Hui Zhou
Optical 3-D nanostructure metrology utilizes a model-based metrology approach to determine critical dimensions (CDs) that are well below the inspection wavelength. Our project at the National Institute of Standards and Technology is evaluating how to

GAUSSIAN PROCESS REGRESSION (GPR) REPRESENTATION IN PREDICTIVE MODEL MARKUP LANGUAGE (PMML)

March 29, 2017
Author(s)
Jinkyoo Park, David Lechevalier, Ronay Ak, Max K. Ferguson, Kincho H. Law, Yung-Tsun Lee, Sudarsan Rachuri
This paper describes a Predictive Model Markup Language (PMML) representation of Gaussian Process Regression (GPR) models. PMML is an XML-based standard language used to represent data mining and predictive analytic models, as well as pre- and post

Chained Bell inequality experiment with high-efficiency measurements

March 28, 2017
Author(s)
Ting Rei Tan, Stephen D. Erickson, Peter L. Bierhorst, Daniel Kienzler, Scott C. Glancy, Emanuel H. Knill, Dietrich G. Leibfried, David J. Wineland, Yong Wan
We report correlation measurements on two 9Be+ ions that violate a chained Bell inequality obeyed by any local-realistic theory. The correlations can be modeled as derived from a mixture of a local-realistic probabilistic distribution and a distribution

Elucidating the Structural and Electronic Properties of Solution-Synthesized 2D SnS Crystals

March 28, 2017
Author(s)
Adam J. Biacchi, Brian G. Alberding, Son T. Le, Joseph A. Hagmann, Sugata Chowdhury, Curt A. Richter, Edwin J. Heilweil, Angela R. Hight Walker
The vast majority of nanoscale 2D materials are synthesized by exfoliation or gas phase deposition techniques. Alternatively, bottom-up colloidal solution syntheses offer a scalable and cost-efficient means of producing 2D nanomaterials in high yield

High Strain Rate Mechanical Characterization of Carbon Fiber Reinforced Polymer Composites using Digital Image Correlations

March 28, 2017
Author(s)
Louise A. Ahure Powell, William E. Luecke, Matthias J. Merzkirch, Timothy J. Foecke, Katherine Avery
The introduction of carbon fiber reinforced polymer (CFRP) composites to structural components in lightweight automotive structures necessitates an assessment to evaluate that their crashworthiness dynamic response provides similar or higher levels of

Magnetic field imaging with microfabricated optically-pumped magnetometers

March 28, 2017
Author(s)
Orang Alem, Rahul Mhaskar, Ricardo Jimenez-Martinez, Dong Sheng, John LeBlanc, Lutz Trahms, Tilman Sander, Svenja A. Knappe
A multichannel imaging system is presented, consisting of 25 microfabricated optically-pumped magnetometers. The sensor probes have a footprint of less than 1 cm2 and a sensitive volume of (1.5 mm)3. They are connected to a control unit through optical

NIST Handbook 150-1, NVLAP Energy Efficient Lighting Products, 2017 Revision

March 28, 2017
Author(s)
C Cameron Miller, Timothy Rasinski
The NIST Handbook 150 publication series sets forth the procedures, requirements, and guidance for the accreditation of testing and calibration laboratories by the National Voluntary Laboratory Accreditation Program (NVLAP). NIST Handbook 150-1, NVLAP

On the Structure and Dynamics of Water Associated with Single-Supported Zwitterionic and Anionic Membranes

March 28, 2017
Author(s)
A. Miskowiec, Z. N. Buck, F. Y. Hansen, H. Kaiser, H. Taub, Madhu Sudan Tyagi, S. O. Diallo, Eugene Mamontov, K. W. Herwig
We have used high-resolution quasielastic neutron scattering (QENS) to investigate the dynamics of water molecules (time scale of motion 10 u-11-10 -9 s) in proximity to singe-supported bilayers of the zwitterionic lipid DMPC (1,2-dimyristoly-sn-glycero-3

Rapid determination of nanowire electrical properties using a dielectrophoresis-well based system

March 28, 2017
Author(s)
Sergiy Krylyuk, Albert Davydov, Marios Constantinou, Kai F. Hoettges, Grigorios P. Rigas, Vlad Stolojan, Maxim Shkunov
The use of high quality semiconducting nanomaterials for advanced device applications has been hampered by the unavoidable variability in the growth of one-dimensional (1D) nanomaterials such as nanowires (NWs) and nanotubes, resulting in highly variable

Report on Lightweight Cryptography

March 28, 2017
Author(s)
Kerry McKay, Lawrence E. Bassham, Meltem Sonmez Turan, Nicky Mouha
NIST-approved cryptographic standards were designed to perform well using general-purpose computers. In recent years, there has been increased deployment of small computing devices that have limited resources with which to implement cryptography. When
