Towards a Virtual Factory Prototype

December 5, 2015
Author(s)
Sanjay Jain, David Lechevalier, Jungyub Woo, Seungjun Shin
A virtual factory should represent most of the features and operations of the corresponding real factory. Some of the key features of the virtual factory include the ability to assess performance at multiple resolutions and generate analytics data similar

Crossover behavior of the thermal conductance and Kramers' transition rate theory

December 4, 2015
Author(s)
Kirill Velizhanin, Subin Sahu, Chih-Chun Chien, Yonatan Dubi, Michael P. Zwolak
Kramers' theory frames chemical reaction rates in solution as reactants overcoming a barrier in the presence of friction and noise. For weak coupling to the solution, the reaction rate is limited by the rate at which the solution can restore equilibrium

Uranium removal from seawater by means of polyamide 6 fibers directly grafted with diallyl oxalate through a single-step, solvent-free irradiation process

December 4, 2015
Author(s)
Travis C. Dietz, Claire E. Tomaszewski, Zois Tsinas, Dianne L. Poster, Aaron Barkatt, Mohammad Adel-Hadadi, Fred B. Bateman, Lonnie Cumberland, Erich Schneider, Karen Gaskell, Jay LaVerne, Mohamad Al-Sheikhly
To test the effectiveness of oxalate-based polymeric adsorbents in the recovery of uranium from seawater, diallyl oxalate (DAOx) was grafted onto polyamide 6 fabrics by exposing the fabric, immersed in pure liquid DAOx or in a surfactant stabilized

Microwave characterization of ink-jet printed CPW on PET substrates

December 3, 2015
Author(s)
Thomas M. Wallis
This paper describes microwave characterization of coplanar waveguide (CPW) lines formed by ink-jet printed technology on flexible polyethylene terephthalate (PET) substrates. The reel-to-reel printing process uses inkjet printing as a precursor for 2$\mu

Energy Use Consequences of Ventilating a Net-Zero Energy House

December 2, 2015
Author(s)
Lisa C. Ng, William V. Payne
A Net-Zero Energy Residential Test Facility (NZERTF) has been constructed at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland to demonstrate that a home similar in size, aesthetics, and amenities to those in the

Observation of Iron Spin-States using Tabletop X-ray Emission Spectroscopy and Microcalorimeter Sensors

December 2, 2015
Author(s)
Young Il Joe, Galen C. O'Neil, Luis Miaja Avila, Joseph W. Fowler, Kevin L. Silverman, Daniel S. Swetz, Joel N. Ullom, Ralph Jimenez
X-ray emission spectroscopy (XES) is a powerful probe of the electronic and chemical state of elemental species embedded within more complex compounds. X-ray sensors that combine high resolving power and high collecting efficiency are desirable for photon

Smart Electronic Laboratory Notebooks for the NIST Research Environment

December 2, 2015
Author(s)
Richard S. Gates, Mark McLean, William A. Osborn
Laboratory notebooks have been a staple of scientific research for centuries for organizing and documenting ideas and experiments. Modern laboratories are more and more reliant on electronic data collection and analysis so it seems inevitable that the

A Labile Hydride Strategy for the Synthesis of Heavily Nitridized BaTiO 3

December 1, 2015
Author(s)
Takeshi Yajima, Fumitaka Takeiri, Kohei Aidzu, Hirofumi Akamatsu, Koji Fujita, Wataru Yoshimune, Masatoshi Ohkura, Shiming Lei, Venkatraman Gopalan, Katsuhisa Tanaka, Craig Brown, Mark Green, Takafumi Yamamoto, Yoji Kobayashi, Hiroshi Kageyama
Oxynitrides, which have been explored extensively in the last decade, exhibit various novel properties beyond oxides, including visible light absorption, photocatalytic activity and high dielectric constants. The synthesis of these oxynitrides generally

Catastrophic Event Phenomena in Communication Networks: A Survey

December 1, 2015
Author(s)
Christopher E. Dabrowski
With the rise of the Internet, there has been increased interest in the use of computer models to study the dynamics of communication networks. An important aspect of this trend has been the study of dramatic, but relatively infrequent, events that result

Datum Planes Based on a Constrained L1 Norm

December 1, 2015
Author(s)
Craig M. Shakarji, Vijay Srinivasan
This paper has two major goals. First, we present an algorithm for establishing planar datums suitable for a default in tolerancing standards. The algorithm is based on a constrained minimization search based on the L_1 (L1) norm after forming a convex
