Bearing Metrics for Health Monitoring of Machine Tool Linear Axes

June 13, 2019
Author(s)
Gregory W. Vogl, Brian C. Galfond, Jordan Jameson
Diagnostics and prognostics of rotating machinery ball bearings is quite mature with an abundance of available methods and algorithms. However, extending these algorithms to other ball bearing applications is challenging and may not yield usable results

Tunable Mechanical Anisotropy, Crack Guiding, and Toughness Enhancement in Two-Stage Reactive Polymer Networks

June 13, 2019
Author(s)
Lewis M. Cox, Adrienne K. Blevins, Jasper A. Drisko, Yifu Ding, Callie I. Higgins, Rong Long, Christopher N. Bowman, Jason P. Killgore
Photopolymers are a versatile group of materials that enable intricate geometric control over printed part geometries in advanced manufacturing processes. However, manufacturing methods attempting to spatially control material heterogeneity within printed

A single-beam slower and magneto-optical trap using a nanofabricated grating

June 11, 2019
Author(s)
Daniel S. Barker, Eric B. Norrgard, Nikolai N. Klimov, James A. Fedchak, Julia K. Scherschligt, Stephen P. Eckel
We demonstrate a compact (0.25 L) system for laser cooling and trapping atoms from a heated dispenser source. Our system uses a nano-fabricated diffraction grating to generate a magneto- optical trap (MOT) using a single input laser beam. An aperture in

CASFinder: Detecting Common Attack Surface

June 11, 2019
Author(s)
Meng Zhang, Yue Xin, Lingyu Wang, Sushil Jajodia, Anoop Singhal
Code reusing is a common practice in software development due to its various benefits. Such a practice, however, may also cause large scale security issues since one vulnerability may appear in many different software due to cloned code fragments. The well

Coherently displaced oscillator quantum states of a single trapped atom

June 11, 2019
Author(s)
Katherine C. McCormick, Jonas Keller, David J. Wineland, Andrew C. Wilson, Dietrich Leibfried
Coherently displaced harmonic oscillator number states of a harmonically bound ion can be coupled to two internal states of the ion by a laser-induced motional sideband interaction. The internal states can subsequently be read out in a projective

Foundations of information governance for smart manufacturing

June 11, 2019
Author(s)
KC Morris, Yan Lu, Simon P. Frechette
The manufacturing systems of the future will be even more heavily dependent on the data than they are today. More and more data and information are being collected and communicated throughout product development lifecycles and across manufacturing value

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
