Quantifying Stability of Trace Explosives under Different Environmental Conditions

April 1, 2017
Author(s)
Edward R. Sisco, Marcela N. Najarro, Daniel V. Samarov, Jeffrey A. Lawrence
This work investigates the stability of trace deposits of six explosives (ETN, PETN, RDX, HMX, TNT, and Tetryl) to determine environmental stabilities and lifetimes. Explosives were inkjet printed directly onto PTFE coated fiberglass substrates and exposed

Biofilm Over Teeth and Restorations, What Do We Need to Know?

March 31, 2017
Author(s)
Nancy Lin
Objectives The goal of this paper is to provide an overview of biofilms and biofilm measurements in the context of studying biofilms on tooth and dental material surfaces to improve oral health. Methods A historical perspective and terminology is presented

Broadband spectral measurements of diffuse optical properties by an integrating sphere instrument at the National Institute of Standards and Technology

March 30, 2017
Author(s)
Paul Lemaillet, Jeeseong Hwang, Heidrun Wabnitz, Dirk Grosenick, Lin Yang, David W. Allen
Diffuse materials that approximate the optical properties of human tissue are commonly used as phantoms. In order to use the phantoms in a manner that provides consistent results relative to independent measurements, the optical properties need to be tied

IFC File Analyzer Software

March 30, 2017
Author(s)
Robert R. Lipman
The IFC File Analyzer software generates a spreadsheet or CSV files from an IFC file. IFC (Industry Foundation Classes) is the data exchange standard used to facilitate interoperability in the building and construction industry. IFC is developed by

Progress in Development of Prepared Foods for Red Drum, Sciaenops ocellatus, That Minimize Inclusion of Fish Meal and Reduce Environmental Impacts of Effluent Discharges

March 30, 2017
Author(s)
Michael R. Denson, Paul A. Sandifer, John Leffler, Justin Yost, Dan Bearden, Thomas R. Zeigler
We conducted a 16-week feeding trial with juvenile red drum (Sciaenops ocellatus). Four diets were randomly assigned to six replicate tanks per treatment. A Basal Diet (Diet 1) contained 19.60% fishmeal and 21.42% poultry meals as primary protein sources

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
