Flame Spread Along Fences Near a Structure in a Wind Field

October 20, 2017
Author(s)
Kathryn M. Butler, Erik L. Johnsson, Marco G. Fernandez, Mariusz Zarzecki, Eric Auth
Combustible fences have been identified in post-fire investigations of wildland-urban interface (WUI) fires as potential threats to homes and other structures. They may ignite due to direct fire contact or firebrands, they may conduct fire along their

Evaluating the Effects of Modeling Errors for Isolated Finite 3-D Targets

October 19, 2017
Author(s)
Mark Alexander Henn, Bryan M. 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

Two determinations of the Ge-68 half-life

October 19, 2017
Author(s)
Denis E. Bergeron, Jeffrey T. Cessna, Brian E. Zimmerman
In nuclear medicine, 68Ge is used to generate 68Ga for imaging by positron emission tomography (PET) and sealed sources containing 68Ge/68Ga in equilibrium have been adopted as long-lived calibration surrogates for the more common PET nuclide, 18F. We

Algorithm for rapid determination of optical scattering parameters

October 18, 2017
Author(s)
Zachary H. Levine, Adam L. Pintar, Richelle H. Streater, Anne-Michelle R. Lieberson, Catherine C. Cooksey, Paul Lemaillet
Preliminary experiments at the NIST Spectral Tri-function Automated Reference Reflectometer (STARR) facility have been conducted with the goal of providing the diffuse optical properties of a solid reference standard with optical properties similar to

Development of A New Atom-Based SI Traceable Electric-Field Metrology Technique

October 18, 2017
Author(s)
Christopher L. Holloway, Matthew T. Simons, Joshua A. Gordon
We are developing a fundamentally new atom-based approach for Electric (E) metrology. This technique has the capability of becoming a new international standard for E-field measurements and calibrations. Since this new approach is based on atomic

Growth-Induced In-Plane Uniaxial Anisotropy V 2 O 3 /Ni Films

October 18, 2017
Author(s)
Dustin Allen Gilbert, Juan Gabriel Ramirez, T. Saerbeck, J. Trastoy, Ivan K. Schuller, Kai Liu, J. de la Venta
We report a microstructure-induced uniaxial anisotropy in V 2O 3/Ni hybrid thin films obtained from temperature and angular dependence of the magnetization. X-ray diffraction and reciprocal space maps identify the in-plane crystalline axes of the V 2O 3

Interference Tests at Room Temperature Applied to Deployed Low-Noise Receivers

October 18, 2017
Author(s)
Daniel G. Kuester, Duncan A. McGillivray, Adam J. Wunderlich, William F. Young
Wireless interference tests are often performed in shielded anechoic and semi-anechoic chambers near room temperature. The corresponding test condition experienced by a receiver DUT is antenna noise temperature equal to physical room temperature (barring
