A Framework to Canonicalize Manufacturing Service Capability Models

May 15, 2015
Author(s)
Boonserm Kulvatunyou, Yunsu Lee, Nenad Ivezic, Yun Peng
The ability to share precise models of suppliers’ manufacturing service capability (MSC) information is necessary to develop reliable methods that enable Original Equipment Manufacturers (OEMs) to efficiently configure agile and responsive supply chains

Improving infiltration modeling in commercial building energy models

May 15, 2015
Author(s)
Lisa C. Ng, Andrew K. Persily, Steven J. Emmerich
As building envelope performance and HVAC equipment efficiencies are increasingly improved to reduce building energy use, a greater percentage of the total energy loss of a building can occur through envelope leakage. Although the energy impacts of

Net-Zero and Beyond! Design and Performance of NIST’s Net-Zero Energy Residential Test Facility

May 15, 2015
Author(s)
Arthur H. Fanney, William V. Payne, Tania Ullah, Lisa C. Ng, Matthew T. Boyd, Farhad Omar, Mark W. Davis, Harrison M. Skye, Brian P. Dougherty, Brian J. Polidoro, William M. Healy, Joshua D. Kneifel, Betsy Pettit
A Net-Zero Energy Residential Test Facility has been constructed at the National Institute of Standards and Technology in Gaithersburg, Maryland. The facility is being used to demonstrate that a home similar in size, aesthetics, and amenities to those in

Spectral homogenization techniques for the hyperspectral image projector

May 15, 2015
Author(s)
Joseph P. Rice, Logan E. Hillberry
In an effort to improve technology for performance testing and calibration of multispectral and hyperspectral imagers, the National Institute of Standards and Technology (NIST) has been developing a Hyperspectral Image Projector (HIP) capable of projecting

A near-infrared 64-pixel superconducting nanowire single photon detector array with integrated multiplexed readout

May 14, 2015
Author(s)
Michael S. Allman, Varun B. Verma, Martin J. Stevens, Thomas Gerrits, Robert D. Horansky, Adriana E. Lita, Francesco Marsili, A. Beyer, Matthew Shaw, D. Kumor, Richard P. Mirin, Sae Woo Nam
We demonstrate a 64-pixel free-space-coupled array of superconducting nanowire single photon detectors optimized for high detection efficiency in the near-infrared range. An integrated, readily scalable, multiplexed readout scheme is employed to reduce the

An Experimental Approach to A Definition of The Mesopic Adaptation Field

May 14, 2015
Author(s)
Tatsukiyo (. Uchida, Yoshihiro Ohno
The CIE 191 mesopic luminous efficiency function depends on the luminance of visual adaptation field, therefore, it must be measured to implement the mesopic photometry method. However, the size and shape of the adaptation field are not defined in CIE 191

Authentication Considerations for Public Safety Mobile Networks

May 14, 2015
Author(s)
Nelson Hastings, Joshua M. Franklin, Larry Feldman, Greg Witte
This bulletin summarizes the information presented in NISTIR 8014, Considerations for Identity Management in Public Safety Mobile Networks, written by Nelson Hastings and Joshua Franklin. The publication analyzes approaches to identity management for

Density-Functional Theory Investigation of Oxidative Corrosion on the UO2(111) Surface

May 14, 2015
Author(s)
Anne M. Chaka, Gloria A. Oxford, Joanne E. Stubbs, Peter J. Eng, John R. Bargar, Thomas P. Trainor
Corrosion and weathering of uranium dioxide (UO2) is a serious concern in a broad range of technological and environmental systems. Oxidation of UO2 can destroy the integrity of nuclear fuel rods, as well as result in the bioavailability of uranium in

New section of the HITRAN database: Collision-Induced Absorption (CIA)

May 14, 2015
Author(s)
Walter J. Lafferty
This paper describes the addition of Collision-Induced Absorption (CIA) into the HITRAN compilation. The data from different sources have been cast into a consistent format and formalism. The implementation of these new spectral data into the HITRAN

Quantitative scheme for full-field polarization rotating fluorescence microscopy (PROM) using a liquid crystal variable retarder

May 14, 2015
Author(s)
John F. Lesoine, Ji Y. Lee, Hyeong G. Kang, Matthew L. Clarke, Robert C. Chang, Ralph Nossal, Jeeseong C. Hwang
We introduce real-time, full-field, polarization rotating fluorescence microscopy (PROM) to monitor the absorption dipole orientations of fluorescent molecules. A quarter-wave plate, in combination with a liquid crystal variable retarder (LCVR), provides a

Raman and Infrared spectra of the ?1 band of oxirane

May 14, 2015
Author(s)
Walter J. Lafferty, Jean-Marie Flaud, F. K. Kwabia Tchana
Fourier transform spectra of oxirane (ethylene oxide, c-C2H4O) have been recorded in the 3.17 μm - 3.5 μm region with a resolution of 0.005 cm-1. In addition, a Raman spectrum covering the same spectral region was recorded at a resolution of 0.44 cm-1

Revealing Integrated Intensity Distributions (RIID)

May 14, 2015
Author(s)
John F. Lesoine
Measuring the distribution of a light sources intensity fluctuations is important to many scientific disciplines. However, these integrated intensity distributions are hidden in noisy experimental photon counting data because of the photometric detection

SI-Traceable Calibrations of Celestial Objects

May 14, 2015
Author(s)
Keith R. Lykke, Claire E. Cramer, John T. Woodward IV
Photometric calibration is currently the leading source of systematic uncertainty in supernova surveys that aim to determine the nature of dark energy. The bulk of this uncertainty is due to imperfect knowledge of the spectral energy distribution of stars

May 14, 2015
Author(s)
K. Tsumura, T. Aria, J. Battle, J. Bock, Steven W. Brown, A. Cooray, V. Hristov, B. Keating, M. G. Kim, D. H. Lee, L. R. Levenson, Keith R. Lykke, P. Mason, T. Matsumoto, S. Matsuura, K. Murata, U. W. Nam, T. Renbarger, Allan W. Smith, I. Sullivan, K. Suzuki, T. Wada, M. Zemcov, U. W. Nam, B. Shultz, I. Sullivan, P. M. Korngut
Absolute spectrophotometric measurements of diffuse radiation at 1−2 μm are crucial to our understanding of the radiative content of the Universe from nucleosynthesis since the epoch of reionization, the composition and structure of the Zodiacal dust cloud
