Geometrical metrology for metal additive manufacturing

June 11, 2019
Author(s)
Richard Leach, David Bourell, Simone Carmignato, Alkan Donmez, Nicola Senin, Wim Dewulf
Metal additive manufacturing technologies facilitate the production of highly complex geometries - this presents designers with many opportunities for high-value sectors but results in manufactured geometries and surfaces that can be difficult to measure

Remote blubber sampling paired with liquid chromatography tandem mass spectrometry for steroidal endocrinology in free-ranging bottlenose dolphins (Tursiops truncatus)

June 11, 2019
Author(s)
Ashley S. Boggs-Russell, Jared M. Ragland, Eric Zolman, Tracey B. Schock, Jeanine S. Morey, Thomas M. Galligan, Greta Dalle Luche, Brian C. Balmer, Randall S. Wells, John R. Kucklick, Lori Schwacke
Liquid chromatography tandem mass spectrometry allows for the measurement of steroid hormone suites in the blubber of marine mammals. By combining this technology with minimally invasive techniques such as remote biopsy, endocrine profiles can be assessed

Configurable error correction of code-division multiplexed TES detectors with a cryotron switch

June 10, 2019
Author(s)
Joel C. Weber, Joseph W. Fowler, Malcolm S. Durkin, Kelsey M. Morgan, John A. Mates, Douglas A. Bennett, William B. Doriese, Daniel R. Schmidt, Gene C. Hilton, Daniel S. Swetz, Joel N. Ullom
The development of a superconducting analog to the transistor with extremely low power dissipation will accelerate the proliferation of low-temperature circuitry operating in the milliKelvin regime. The thin-film, magnetically actuated cryotron switch is a

Design Space Exploration for Wireless-Integrated Factory Automation Systems

June 10, 2019
Author(s)
Jing Jeng, Honglei Li, Yongkang Liu, Mohamed Hany, Rick Candell, Shuvra Bhattacharyya
Recent years have brought significantly increased interest in integrating wireless communication capabilities within factory automation systems. Such integration motivates the study of interactions among the physical layout of factory workcells, wireless

BotSifter: A SDN-based Online Bot Detection Framework in Data Centers

June 9, 2019
Author(s)
An Wang, Zili Zha, Yang Guo, Douglas Montgomery, Songqing Chen
Botnets continue to be one of the most severe security threats plaguing the Internet. Recent years have witnessed the emergence of cloud-hosted botnets along with the increasing popularity of cloud platforms, which attracted not only various applications

Creating Training Data for Scientific Named Entity Recognition with Minimal Human Effort

June 8, 2019
Author(s)
Roselyne B. Tchoua, Aswathy Ajith, Zhi Hong, Logan T. Ward, Kyle Chard, Debra Audus, Shrayesh N. Patel, Juan J. de Pablo, Ian Foster
Scientific Named Entity Referent Extraction is often more complicated than traditional Named Entity Recognition (NER). For example, in polymer science, chemical structure may be encoded in a variety of nonstandard naming conventions, and authors may refer

Bubble magnetometry of nanoparticle heterogeneity and interaction

June 7, 2019
Author(s)
Andrew L. Balk, Ian J. Gilbert, R. Ivkov, John Unguris, Samuel Stavis
Bubbles have a rich history as transducers in particle-physics experiments. In a solid-state analogue, we use bubble domains in nanomagnetic films to measure magnetic nanoparticles. This technique can determine the magnetic orientation of a single

Infrared electric-field sampled frequency comb spectroscopy

June 7, 2019
Author(s)
Abijith S. Kowligy, Henry R. Timmers, Alexander Lind, Ugaitz Elu, Flavio Caldas da Cruz, Peter Schunemann, Jens Biegert, Scott Diddams
Molecular spectroscopy in the mid-infrared portion of the electromagnetic spectrum (3--25 um) has been a cornerstone interdisciplinary analytical technique widely adapted across the biological, chemical, and physical sciences. Applications range from

Near-Unity Spin Hall Ratio in Ni$_x$Cu$_{1-x}$ Alloys

June 7, 2019
Author(s)
Mark W. Keller, Katy Gerace, Monika Arora, Justin M. Shaw, Thomas J. Silva
We report a large spin Hall effect in the 3$d$ transition metal alloy Ni$_x$Cu$_{1-x}$ for $x \in \{ 0.3,0.75\} $, detected via the ferromagnetic resonance of a permalloy (Py = Ni$_{80}$Fe$_{20}$) film deposited in a bilayer with the alloy. A thickness

VISCOSITY OF GASES

June 7, 2019
Author(s)
Marcia L. Huber
This is a chapter in CRC that contains tables with viscosity of gases

A SysML Representation of the Wireless Factory Work-cell

June 6, 2019
Author(s)
Richard Candell, Mohamed T. Hany, Yongkang Liu, Sebti Foufou
Smart Manufacturing, also known as Industry 4.0, provides a vision of future manufacturing systems that incorporate highly dynamic physical systems, robust and responsive communications systems, and computing paradigms to maximize efficiency, enable

Efficient volumetric non-destructive testing methods for additively manufactured parts

June 6, 2019
Author(s)
Anne-Francoise Obaton, Bryan Butsch, Ewen Carcreff, Nans Laroche, Jared B. Tarr, Alkan Donmez
As additive manufacturing (AM) moves towards industrial production in critical sectors such as aerospace and medical, the integrity of the fabricated AM parts need to be ensured in order for these parts to be certified. This requires quality controls

Magneto-optic trap using a reversible, solid-state alkali-metal source

June 6, 2019
Author(s)
Songbai Kang, Kaitlin R. Moore, James P. McGilligan, R. Mott, A. Mis, C. Roper, Elizabeth A. Donley, John E. Kitching
Fast, reversible, and low-power alkali-atom sources are desirable in both tabletop and portable cold-atom sensors. Here we demonstrate a magneto-optic trap (MOT) formed in conjunction with a reversible solid state Rb reservoir in a vapor cell. The results
