Nail to Nail Fingerprint Challenge: Enrollment Set Size Variability

June 24, 2019
Author(s)
Gregory P. Fiumara, Kenneth Ko, Elham Tabassi, Patricia A. Flanagan, John D. Grantham, Karen Marshall, Matthew Schwarz, Bryan Woodgate
In September 2017, the Intelligence Advanced Research Projects Activity held a fingerprint data collection as part of the Nail to Nail Fingerprint Challenge. Thousands of latent fingerprint images collected at the Challenge were searched against rolled

pyMCR: A Python Library for Multivariate Curve Resolution Analysis

June 24, 2019
Author(s)
Charles H. Camp
In this work, a new software library is presented for performing multivariate curve resolution (MCR)analysis, a chemometric method for elucidating signatures of analytes ("endmember extraction") and their relative abundance (regression) from a series of

Optimization of Air-to-Refrigerant Evaporator with Low-GWP Refrigerants

June 23, 2019
Author(s)
Piotr A. Domanski
An analytical evaluation of the performance of low-GWP refrigerants in a finned-tube evaporator used for residential cooling applications will be presented. The study employed an evolutionary-computation optimization module to examine the effect of a

A Truth-Matrix View into Unary Computing

June 22, 2019
Author(s)
Advait Madhavan, Georgios Tzimpragos, Mark D. Stiles, Timothy Sherwood
Our community has been exploring Time-of-arrival based codes as a candidate for very low energy information processing. A ``space-time'' algebra has been recently proposed that captures the essential features of such a paradigm. In order to gain some

Effect of Adjacent Hydrophilic Polymer Thin Films on Physical Aging and Residual Stress in Thin Films of Poly(butylnorbornene-ran-hydroxyhexafluoroisopropyl norbornene)

June 22, 2019
Author(s)
Elizabeth A. Lewis, Christopher Stafford, Bryan D. Vogt
The properties of thin supported polymer films can be dramatically impacted by the substrate upon which it resides. A simple way to alter the properties of the substrate (chemistry, rigidity, dynamics) is by coating it with an immiscible polymer. Here we

An Implementation Proposal for IEEE 802.11ay SU/MU-MIMO Communication in ns-3

June 21, 2019
Author(s)
Hany Assasa, Joerg Widmer, Jian Wang, Tanguy Ropitault, Nada T. Golmie
Wireless communications in the millimeter-wave band bring unprecedented capabilities to achieve wireline performance in wireless networks and alleviate the congestion problem of current wireless technologies. However, efficient wireless networking in this

Analysis of Different Computational Techniques for Calculating the Polarizability Tensors of Stem Cells with Realistic Three-Dimensional Morphologies

June 21, 2019
Author(s)
Edward Garboczi, Jack Douglas, Beatriz Pazmino, Ahmed M. Hassan, Somen Baidya
Recent advances in synthetic biomaterial microenvironment design has enabled researchers to mimic the natural in vivo environment of the cell and, therefore, quantify the effect of the environment on the morphologies of stem cells. Recently, the National

Quantum amplification of motion of a mechanical oscillator

June 21, 2019
Author(s)
Shaun C. Burd, Raghavendra Srinivas, John J. Bollinger, Andrew C. Wilson, David J. Wineland, Dietrich G. Leibfried, Daniel H. Slichter, David T. Allcock
Detection of the weakest forces in nature and the search for new physics demand increasingly sensitive measurements of the motion of mechanical oscillators. However, the attainable knowledge of an oscillator’s motion is limited by quantum fluctuations that

Revealing the distribution of metal carboxylates in oil paint from the micro- to the nanoscale

June 21, 2019
Author(s)
Xiao Ma, Victoria Beltran, Georg Ramer, Georges Pavlidis, dilworth parkinson, Mathieu Thoury, Tyler Meldrum, Andrea Centrone, Barbara H. Berrie
Oil paints comprise pigments, drying oils, and additives that together confer desirable properties, but can react forming metal carboxylates (soaps) that, over time, may damage artworks. Despite substantial research to understand these phenomena, soap

The Art in Science of MicroTAS 2018

Author(s)
Gregory A. Cooksey
The 2018 MicroTAS conference (the 22nd International Conference of Miniaturized Systems for Chemistry and Life Sciences) took us to Kaohsiung, Taiwan, for an inspiring mix of science and culture. The Art in Science competition, sponsored by Lab on a Chip

Crystallographic and Optical Properties of Ba(Co1-xZnx)SiO4 (x = 0.2, 0.4, 0.6, 0.8)

June 20, 2019
Author(s)
Rola M. Derbeshi, Winnie Wong-Ng, Jude Anike, Wei Fang Liu, Nacole B. King, Shouyu Wang, James A. Kaduk, Yucheng Lan
Structural characterization and X-ray reference powder pattern determination have been condcuted for the Co- and Zn-containing tridymite derivatives Ba(Co1-xZnx)SiO4 (x = 0.2, 0.4, 0.6, 0.8). The bright blue series of Ba(Co1-xZnx)SiO4 crystallized in the

Decision Support for Smart Grid: Using Reasoning to Contextualize Complex Decision Making

June 20, 2019
Author(s)
Edward R. Griffor, David A. Wollman, Patrick Kamongi, Claire Vishik, Michael Huth, Marcello Balduccini
The smart grid is a complex cyber-physical system (CPS) that poses challenges related to scale, integration, interoperability, processes, governance, and human elements. The US National Institute of Standards and Technology (NIST) and its government

FEA solver integration framework

June 20, 2019
Author(s)
Conrad E. Bock, Jerome Szarazi
Integrating finite element analysis (FEA) with systems engineering (SE) would improve traceability, consistency, and interoperability between SE and FEA activities in multiple engineering disciplines. The first step in achieving this is a software
