Noncontact conductivity and dielectric measurement for high throughput roll-to-roll nanomanufacturing

November 23, 2015
Author(s)
Nathan D. Orloff, Christian J. Long, Jan Obrzut, Laurent Millaud, Francesca Mirri, Thomas R. Kole, Robert D. McMichael, Mattei Pasquali, Stephan J. Stranick, James A. Liddle
Advances in roll-to-roll processing of graphene [1] and carbon nanotube [2] have at last led to the continuous production of high-quality coatings and filaments, ushering in a wave of applications for flexible [3], [4] and wearable [5] electronics, woven

A Constrained L2 Based Algorithm for Standardized Planar Datum Establishment

November 18, 2015
Author(s)
Craig M. Shakarji, Vijay Srinivasan
For years (decades, in fact) a definition for datum planes has been sought by ASME and ISO standards writers that combines the contacting nature of traditional surface plate mating with a means of balancing rocking conditions when there is a centrally

On the Internet Connectivity in Africa

November 18, 2015
Author(s)
Assane Gueye, Peter Mell, Desire Banse, Faical Y. Congo
This study measures and documents growth of Internet connectivity in Africa from 2010 to 2014 with a focus on inter-country relationships. We evaluate both intra-continent connectivity as well as connectivity to other continents. An initial analysis

Quantification of Borrelia burgdorferi membrane proteins in human serum: a new concept for detection of bacterial infection

November 17, 2015
Author(s)
Sao F. Cheung, Kyle Anderson, Kenia Benitez, Mark J. Soloski, John N. Aucott, Karen W. Phinney, Illarion Turko
The low abundance of bacterial proteins in human serum upon infection imposes a challenge for the early proteomic detection of bacterial infection. To address this challenge, we propose to take advantage of detecting membrane proteins released from

Hydrogen Field Test Standard: Laboratory and Field Performance

November 10, 2015
Author(s)
Jodie G. Pope, John D. Wright
The National Institute of Standards and Technology (NIST) developed a prototype field test standard (FTS) that incorporates three test methods that could be used by state weights and measures inspectors to periodically test retail hydrogen dispensers, much

Applications of the Spline Filter for Areal Filtration

November 4, 2015
Author(s)
D Ott, Hao H. Zhang, Daniel B. Ott, Wei Chu, Jun-Feng Song
This paper proposes a general use areal isotropic spline filter. This new areal spline filter can achieve isotropy by approximating the transmission characteristic of the Gaussian filter. It can also eliminate the effect of void areas using a weighting

Electrostatic Microprobe for Determining Charge Domains on Surfaces

November 2, 2015
Author(s)
Robert A. Fletcher
The electrostatic microprobe is a laboratory constructed instrument with the design purpose to measure charge content on wipe and various control surfaces. The device is constructed on an optical microscope platform, with a computer automated XY stage

Evaluation of the Range Performance of Laser Scanners Using Non-planar Targets.

November 1, 2015
Author(s)
Prem K. Rachakonda, Balasubramanian Muralikrishnan, Craig M. Shakarji, Vincent D. Lee, Daniel S. Sawyer
The Dimensional Metrology Group (DMG) at the National Institute of Standards and Technology (NIST) is supporting the development of documentary standards for performance evaluation of Laser scanners. This evaluation could be performed by determining the

Design and calibration of an artifact for evaluating laser scanning articulating arm CMMs used for measuring complex non-concurrent surfaces

October 30, 2015
Author(s)
Vincent D. Lee, Steven D. Phillips, Craig M. Shakarji, Jeffrey Hosto, Jeffrey Huber, Gillich Barbara
Dimensional metrology is a foundational science finding applications throughout modern technology, including the testing of human-worn body armor designed to mitigate damage from kinetic projectiles fired from small arms. We describe the design and
