Experimental Characterization of the Advanced Liquid Hydrogen Cold Neutron Source Spectrum of the NBSR Reactor at the NIST Center for Neutron Research

August 1, 2015
Author(s)
Jeremy C. Cook, John G. Barker, J. Michael Rowe, Robert E. Williams, Cedric V. Gagnon, Richard M. Lindstrom, Richard Michael Ibberson, Dan A. Neumann
The recent expansion of the NIST Center for Neutron Research facility has offered a rare opportunity to perform an accurate measurement of the cold neutron spectrum at the exit of a newly-installed neutron guide. Using a combination of a neutron time-of

ANALYSES OF ERRORS ASSOCIATED WITH PHOTOMETRIC DISTANCE IN GONIOPHOTOMETRY

Yoshihiro Ohno, V. Jacobs, Peter Blattner, Tony Bergen, Udo Krueger, P. Rombauts, F. Schmidt, Peter Hanselaer
In lighting calculations and simulations, the emission of a light source is conventionally modelled using the far-field intensity, also termed luminous intensity distribution (LID). Previous studies have indicated that the traditional limiting photometric

Atomically thin layers of B-N-C-O with tuneable composition

Ann C. Chiaramonti Debay, Birol Ozturk, Andres de Luna Bugallo, Eugene Panaitescu, Fangze Liu, Anthony Vargas, Xueping Jiang, Ozgur Yavuzcetin, Majed Alnaji, Yongui Zhao, Nicholas King, Madan Dubey, Saroj Nayak, Srinivas Sridhar, Swastik Kar
Atomically thin ternary compounds/alloys of boron, nitrogen and carbon have generated significant excitement as they provided the first instance of a tuneable 2D material that affords rich physics as well applications potentials. Interestingly, the crucial

VISION EXPERIMENT ON CHROMA SATURATION FOR COLOR QUALITY PREFERENCE

July 31, 2015
Author(s)
Yoshihiro Ohno, Carl C. Miller, Mira Fein
Color Rendering Index (CRI) often does not correlate well with visual evaluation of color rendering of light sources at real illuminated scenes. The main reason is that CRI measures color fidelity, while general users judge color rendering based on their

Analysis of Network Segmentation Techniques in Cloud Data Centers

Ramaswamy Chandramouli
Cloud Data centers are predominantly made up of Virtualized hosts. The networking infrastructure in a cloud (virtualized) data center, therefore, consists of the combination of physical IP network (data center fabric) and the virtual network residing in

Ignition of Wood Fencing Assemblies Exposed to Continuous-Wind Driven Firebrand Showers

July 30, 2015
Author(s)
Sayaka Suzuki, Erik L. Johnsson, Alexander Maranghides, Samuel Manzello
A series of experiments were conducted to examine ignition of wood fencing assemblies subjected to continuous, wind-driven firebrand showers. Specifically, Western Red Cedar and Redwood fencing assemblies were exposed to continuous, wind-driven firebrand
