Cyber-Physical Systems Framework

November 2, 2015
Author(s)
David A. Wollman
Two worlds that have operated independently—the digital and physical worlds—are now merging, creating opportunities that will transform many sectors of our society. These new smart systems are based on engineered interacting networks of physical and

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

Injection Locking of a Semiconductor Double Quantum Dot Micromaser

November 2, 2015
Author(s)
Michael Gullans, Y.-Y. Liu, J. Stehlik, Jacob M. Taylor, Jason Petta
The semiconductor double quantum dot (DQD) micromaser generates photons through single electron tunneling events. Charge noise couples to the DQD energy levels, resulting in a maser linewidth that is 100 times larger than the Schawlow-Townes prediction. We

Photomask Linewidth Comparison by PTB and NIST

November 2, 2015
Author(s)
Detleff Bergmann, Bernd Bodermann, Harald Bosse, Egbert Buhr, Gaoliang Dai, Ronald G. Dixson, W H?er-Grohne
We report the initial results of a recent bilateral comparison of linewidth or critical dimension (CD) calibrations on photo-mask line features between two national metrology institutes (NMIs): the National Institute of Standards and Technology (NIST) in

The Fiber Break Evolution Process in a 2-D Epoxy/Glass Multi-Fiber Array

November 2, 2015
Author(s)
Edward D. McCarthy, Jae H. Kim, N. Alan Heckert, Stefan D. Leigh, Jeffrey W. Gilman, Gale A. Holmes
The mechanical integrity of a structural composite is strongly affected by the strength and toughness of the fiber-matrix interface/interphase [1], with interfacial shear strength (IFSS) being the accepted quanti-fying metric. However, the value of the

Analysis and Optimization in Smart Manufacturing based on a Reusable Knowledge Base for Process Performance Models

November 1, 2015
Author(s)
Alexander Brodsky, Guodong Shao, Mohan Krishnamoorthy, Anantha Narayanan Narayanan, Daniel Menasce?, Ronay Ak
In this paper, we propose an architectural design and software framework for fast development of descriptive, predictive, diagnostic, and prescriptive analytics solutions for dynamic production processes. The proposed architecture and framework are based

Combinatorial Analysis of Diagonal, Box and Greater-Than Polynomials as Packing Functions

November 1, 2015
Author(s)
Pepe Torres Jimenez, Nelson Rangel-Valdez, Raghu N. Kacker, James F. Lawrence
Packing functions (PFs) are bijections between a set of m-dimensional vectors V over N m and nonnegative integers N. PFs have several applications, e.g. in partitioning schemes or text compression. Two important categories of PFs are diagonal polynomials

DNA Extraction and DNA Damage Measurement in the Nematode Caenorhabditis elegans

November 1, 2015
Author(s)
Leona D. Scanlan, Pawel Jaruga, Sanem Hosbas Coskun, Jamie L. Almeida, David N. Catoe, Jennifer McDaniel, Miral M. Dizdar
Little is known about endogenous DNA damage in the nematode. In this work, we standardized the growth of the nematode in two different growth media (axenic CeHR supplemented with 20% milk and S-basal with E. coli), and developed a novel high-salt, phenol

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
