Simulating Occupancy in The NIST Net-Zero Energy Residential Test Facility

November 21, 2013
Author(s)
Farhad Omar, Steven T. Bushby
The Net-Zero Energy Residential Test Facility (NZERTF), at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland, is a research house that is comparable in size and aesthetic to the houses in the greater Washington DC metro

The Process of Verification and Validation of Building Fire Evacuation Models

November 21, 2013
Author(s)
Enrico Ronchi, Erica D. Kuligowski, Paul A. Reneke, Richard Peacock, Daniel Nilsson
To date, there is no International standard on the methods and tests to assess the verification and validation (V&V) of building fire evacuation models, i.e., model testers adopt inconsistent procedures or tests designed for other model uses. For instance

TOWARDS THE SYNTHESIS OF PRODUCT KNOWLEDGE ACROSS THE LIFECYCLE

November 21, 2013
Author(s)
Paul W. Witherell, Boonserm Kulvatunyou, Sudarsan Rachuri
Product lifecycle management is an important aspect of today’s industry, as it serves to facilitate information exchange and management between most, if not all, stages of a product’s existence. As exchanged product information is inevitably subjected to

Componentization in the Systems Modeling Language

November 20, 2013
Author(s)
Conrad E. Bock
This paper describes new capabilities in the Systems Modeling Language that reduce the complexity of specifying systems through componentization, and increase the range of systems that can be specified. Modelers can identify portions of components

Web Based 3D Visualization and Interaction for Whole Body Laser Scans

November 20, 2013
Author(s)
Sanford P. Ressler
A web based system that allows the user to select, sort, and measure 3D bodies using displays inside of ordinary web browsers without the use of 3D plug-ins is presented. Our system, AnthroWeb3DMeasure (AW3DM), allows the user to visually explore a set of

Chirality from interfacial spin-orbit coupling effects in magnetic bilayers

November 19, 2013
Author(s)
Kyoung-Whan Kim, Hyun-Woo Lee, Kyung Jin Lee, Mark D. Stiles
Spin-orbit coupling causes many properties that make magnets technologically important as well as properties that interfere with optimal performance. As nanomagnetic devices scale to smaller sizes, spin-orbit coupling due to the broken structural inversion

Infrared Laboratory Oscillator Strengths of Fe I in the H-Band

November 19, 2013
Author(s)
Matthew Ruffoni, J C. Pickering, C. Allende Prieto, Gillian Nave
We report experimental oscillator strengths for 28 infrared Fe I transitions, for which no previous experimental values exist. These transitions were selected to address an urgent need for oscillator strengths of lines in the H-band (between 1.4 μm and 1.7

Switching the Adhesive State of Catacholic Hydrogels using Phototitration

November 19, 2013
Author(s)
Evan M. White, Jonathan Seppala, Parker M. Rushworth, Suraj Sharma, Jason Locklin
A polyacrylamide hydrogel system that can be liquefied by remote activation using UV irradiation was investigated as a degradable adhesive. The linear polyacryamide copolymer, formed by conventional free-radical polymerization, contains biomemetic catechol

Efficient quantification of experimental evidence against local realism

November 18, 2013
Author(s)
Yanbao Zhang, Scott C. Glancy, Emanuel H. Knill
To statistically quantify the evidence against local realism in an experiment, it is desirable to bound the probability according to local realism of a violation at least as high as that observed. We describe an efficient protocol for computing such a

Identification and elimination of anomalous thermal decay in gamma-ray microcalorimeters

November 18, 2013
Author(s)
Robert D. Horansky, Douglas A. Bennett, Daniel R. Schmidt, Barry L. Zink, Joel N. Ullom
Microcalorimeter detectors rely on superconducting components and cryogenic temperatures to provide over an order-of-magnitude improvement in energy resolution compared to semiconducting sensors. Resolution improvements impact fields from gamma-ray

Isnt it time to get serious about standards?

November 18, 2013
Author(s)
Kristine A. Bertness
Current methods of composition measurement lack the ability to produce consistent results from laboratory to laboratory and across companies. NIST has developed AlGaAs SRMs to make standardization possible, but the standards need to be used. This opinion

Quest for a Highly Connected Robust Porous Metal-Organic Framework on the Basis of a Bifunctional Linear Linker and a Rare Heptanuclear Zinc Cluster

November 18, 2013
Author(s)
Wen-Yang Gao, Rong Cai, Le Meng, Lukasz Wojtas, Wei Zhou, Taner N. Yildirim, Xiaodong Shi, Shengqian Ma
A strategy for achieving high-connected robust MOFs by linear ligands is exemplified by the construction of MTAF-4, a rare (6, 9)-connected 10 MOF based upon the custom-designed bifunctional linear ligand, 4-(1,2,3-triazol-4-yl)-benzoate that connects two

Absolute individual line intensities of numerous transitions of the fundamental ν2 and ν10 bands of oxirane (ethylene oxide, c-C2H4O) have been measured in the 1420-1560 cm-1 region using seven high- resolution Fourier transform spectra recorded at 0.002

Walter J. Lafferty, Jean-Marie Flaud, Fridolin Kwabia, A. Perrin, M. Ngom
Seven Fourier transform spectra of the ν3 band of oxirane (ethylene oxide) have been recorded with different pressures and used to derive individual line intensities. These line intensities were satisfactorily fit leading to accurate transition moment
