Microgravity Superagglomerates Produced by Silane and Acetylene

February 19, 2017
Author(s)
Matthew Bundy, George Mulholland, Samuel Manzello, Jiann C. Yang, J H. Scott
A study of acetylene and silane diffusion flames was performed in normal gravity (1-g) and microgravity ([mu]-g) to determine the evolution of soot and silica agglomerates. The objective of this study was to understand the process of gas phase

Toward Integrating Distributed Energy Resources and Storage Devices in the Smart Grid

February 1, 2017
Author(s)
Guobin Xu, Wei Yu, David W. Griffith, Nada T. Golmie, Paul Moulema
The smart grid, as one of typical applications supported by Internet of Things, denoted as a re-engineering and a modernization of the traditional power grid, aims to provide reliable, secure, and efficient energy transmission and distribution to consumers

Generalized entropy theory of glass-formation in fully flexible polymer melts

December 21, 2016
Author(s)
Jack F. Douglas, Wensheng Xu, Karl Freed
The generalized entropy theory (GET) offers many insights into how molecular parameters influence polymer glass-formation. Given the fact that chain rigidity often plays a critical role in understanding the glass- formation of polymer materials, the GET

Rheological Measurement of Suspensions Without Slippage: Experimental and Model

December 13, 2016
Author(s)
Alex Olivas, Michelle A. Helsel, Nicos Martys, Chiara C. Ferraris, William L. George, Raissa Ferron
The conclusion of international studies was that the optimal approach to calibrate concrete rheometers would be to develop a non-Newtonian standard reference material (SRM) that contained inclusions similar in size to aggregates used commonly in concrete

Continuous-feed optical sorting of aerosol particles

June 15, 2016
Author(s)
John J. Curry, Zachary H. Levine
We consider the problem of sorting, by size, spherical particles of order 100 nm radius. The scheme we analyze consists of a heterogeneous stream of spherical particles flowing at an oblique angle across a Gaussian mode optical standing wave. Sorting is

Considerations of Environmentally-Relevant Test Conditions for Improved Evaluation of Ecological Hazards of Engineered Nanomaterials

June 8, 2016
Author(s)
Patricia Holden, Jorge Gardea-Torresdey, Frederick Klaessig, Ronald Turco, Monika Mortimer, Kerstin Hund-Rinke, David Avery, Damia Barcelo, Renata Behra, Yoram Cohen, Laurence Deydier-Stephan, Barbara Harthorn, Danail Hristozov, John Johnston, Agnes Kane, Larry Kaputska, Arturo Keller, Hunter Lenihan, Wess Lovell, Catherine Murphy, Roger Nisbet, Elijah Petersen, Martin Scheringer, Monita Sharma, David Speed, Yasir Sultan, Jason White, Eva Wong, Baoshan Xing, Meghan Steele Horan, Hilary Godwin, Andre Nel
Engineered nanomaterials (ENMs) entering the environment could impact biological populations or entire ecosystems. Ecotoxicology aims to determine effective concentrations, which often exceed those in the environment. ENM behaviors in complex media impede

CONTAM RESULTS EXPORT TOOL

March 9, 2016
Author(s)
Brian Polidoro, Lisa Ng, William Stuart Dols
CONTAM is a multizone indoor air quality and ventilation analysis program developed by the National Institute of Standards and Technology (NIST). Since CONTAM simulation files are binary and not human-readable, the CONTAM Results Export Tool was created to

Measuring Systematic and Random Error in Digital Forensics

July 24, 2015
Author(s)
Alexander J. Nelson, Simson L. Garfinkel
Recognized sources of error in digital forensics include systematic errors arising from implementation errors, and random errors resulting from faulty equipment. But as digital forensic techniques expand to include statistical machine learning, another

Gd(sub 90)Co(sub 2.5)Fe(sub 7.5) Alloy Displaying Enhanced magnetocaloric Properties

July 3, 2015
Author(s)
Virgil Provenzano, Robert D. Shull, G Kletetschka, Paul E. Stutzman
Because of its attractive magnetocaloric properties, gadolinium (Gd) metal is currently the refrigerant of choice in the development of near-room temperature magnetic cooling prototypes (refrigerators, heat pumps, and air conditioners). The overwhelming

Research Roadmap for Smart Fire Fighting

June 11, 2015
Author(s)
Anthony P. Hamins, casey grant, Nelson P. Bryner, Albert W. Jones, Galen H. Koepke
… systems through the fusion of emerging sensor and computing technologies with building control systems, …

The impact of current CH4 and N2O atmospheric loss process uncertainties on calculated ozone abundances and trends

May 29, 2015
Author(s)
Vladimir L. Orkin, Eric L. Fleming, Christian George, Dwayne E. Heard, Charles H. Jackman, Michael J. Kurylo , Abdelwahid Mellouki , J B. Burkholder
The atmospheric loss processes of N2O and CH4, their estimated uncertainties, lifetimes, and impacts on ozone abundance and long-term trends are examined using atmospheric model calculations and updated kinetic and photochemical parameters and uncertainty

Structures and thermoelectric properties of double-filled (CaxCe1-x)Fe4Sb12 skutterudites

July 9, 2014
Author(s)
Yonggao Y. Yan, Winnie Wong-Ng, James A. Kaduk, Matthew Suchomel, Xiang Sun, Gangjian Tan, Xinfeng Tang, Lan (. Li, Igor Levin
The structures and thermoelectric properties of double-filled (CaxCe1-x)Fe4Sb12 series (x=0, 0.25, 0.5, 0.75, and 1) have been investigated using the combination of experimental and computational approaches. Structural analysis shows that single phases of

Evaluating the Uncertainty of Input Quantities in Measurement Models

May 28, 2014
Author(s)
Antonio M. Possolo
The Guide to the Expression of Uncertainty in Measurement gives guidance about how values and uncertainties should be assigned to the input quantities that appear in measurement models. This contribution offers a concrete proposal for how that guidance may

Report on High-Rise Fireground Field Experiments

April 10, 2013
Author(s)
Jason D. Averill, Lori Moore-Merrell, Raymond T. Ranellone Jr., Craig G. Weinschenk, Nicole Taylor, Randy Goldstein, Robert Santos, Doug Wissoker, Kathy Notarianni, Kathryn Butler
In order to balance community expectations with limited resources, the fire service and community leaders require scientific data that quantifies the effects of changes in fire service deployment on the safety of the public and firefighters. This report

Logic Minimization Techniques with Applications to Cryptology

April 1, 2013
Author(s)
Joan Boyar, Philip Matthews, Rene Peralta
A new technique for combinational logic optimization is described. The technique is a two-step process. In the rst step, the non-linearity of a circuit as measured by the number of non-linear gates it contains is reduced. The second step reduces the number
