Background Radiation Measurements at High Power Research Reactors

January 11, 2016
Author(s)
Hans P. Mumm
Research reactors typically host a wide range of activities that make use of the intense neutron fluxes generated at these facilities. Recent interest in performing measurements with relatively low event rates, e.g. reactor antineutrino detection, at these

Fast Lithium-Ionic Conduction in a New Complex Hydride-Sulphide Crystalline Phase

January 11, 2016
Author(s)
Atsushi Unemoto, Hui Wu, Terrence J. Udovic, Motoaki Matsuo, Tamio Ikeshoji, Shin-Ichi Orimo
A new crystalline phase derived from a 90LiBH 4:10P 2S 5 mixture displays high lithium-ionic conductivity of log(ς/S cm -1) = 3.0 at 300 K. It is stable up to 473 K and has both a wide potential window of 0-5 V and favorable mechanical properties for

Securing Interactive and Automated Access Management Using Secure Shell (SSH)

January 11, 2016
Author(s)
Murugiah P. Souppaya, Karen Scarfone, Larry Feldman
This bulletin summarizes the information presented in NISTIR 7966, "Security of Interactive and Automated Access Management Using Secure Shell (SSH)". The publication assists organizations in understanding the basics of SSH interactive and automated access

A metamodel for optimization problems

January 8, 2016
Author(s)
Ibrahim Assouroko, Peter O. Denno
In mathematics, computer science, and operations research, mathematical optimization is the process of finding best feasible values (oftentimes maxima or minima) of a given objective that is modeled mathematically. This paper introduces the concept of a

Calibration and Measurement Procedures for a High Magnification Thermal Camera

January 8, 2016
Author(s)
Brandon M. Lane, Eric P. Whitenton
Infrared thermography is a relatively mature measurement science, however systematic evaluation of measurement uncertainty for multi-point measurement (an infrared focal plane array) is very limited, or, does not follow uncertainty evaluation guidelines

DBSR_HF: A B-spline Dirac-Hartree-Fock program

January 8, 2016
Author(s)
O Zatsarinny, Charlotte F. Fischer
A B-spline version of a general Dirac-Hartree-Fock program is described. The usual differential equations are replaced by set of generalized eigenvalue problems of the form (Ha . åa B)Pa = 0, where Pa designates the two-component relativistic orbital in B

Fe-catalyzed etching of exfoliated graphite through carbon hydrogenation

January 8, 2016
Author(s)
Guangjun Cheng, Christina A. Hacker, Curt A. Richter, Angela R. Hight Walker
We present an investigation on the etching of graphite catalyzed by the particles produced by dewetting Fe thin films on graphite in forming gas. Raman mapping of the etched graphite shows the thickness variation in the etched channels and reveals that the

Surface-directed Nanoepitaxy on a Surface with an Irregular Lattice

January 8, 2016
Author(s)
Elias J. Garratt, Babak Nikoobakht
Understanding and developing metrics on how nanocrystals respond to local external surface stimuli at their interfaces during growth or operation is a key step in advancing scalable and deterministic approaches for fabricating functional one- and two

Survey Statistics of Automated Segmentations Applied to Optical Imaging of Mammalian Cells

January 8, 2016
Author(s)
Peter Bajcsy, Antonio Cardone, Joe Chalfoun, Michael W. Halter, Derek Juba, Marcin Kociolek, Michael P. Majurski, Adele P. Peskin, Carl G. Simon Jr., Mylene H. Simon, Antoine Vandecreme, Anne L. Plant, Mary C. Brady
The goal of this survey paper is to overview cellular measurements using optical microscopy imaging followed by automated image segmentation. The cellular measurements of primary interest are taken from mammalian cells and their components. They are
