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

Interlaboratory study to validate a STR profiling method for intraspecies identification of mouse cell lines

June 20, 2019
Author(s)
Jamie L. Almeida, Aleksandra Dakic, Karin Kindig, Maikan Kone, Deborah L. Letham, Scott Langdon, Ruth Peat, Jayamalini Holding-Pillai, Erin Hall, Mark Ladd, Megan Shaffer, Heath Berg, Jinliang Li, Georges Wigger, Steven P. Lund, Carolyn R. Steffen, Barbara Fransway, Bob Geraghty, Manuela Natoli, Beth Bauer, Susanne M. Gollin, Dale Lewis, Yvonne A. Reid
The Consortium for Mouse Cell Line Authentication was formed to validate Short Tandem Repeat (STR) markers for intraspecies identification of mouse cell lines. The STR profiling method is a multiplex polymerase chain reaction (PCR) assay comprised of

W -Band Vibrometer for Noncontact Thermoacoustic Imaging

June 20, 2019
Author(s)
Archita Hati, Craig Nelson
Noncontact thermoacoustic imaging (TAI) has several desirable characteristics for applications such as explosive detection in high-water-content media. In this letter, we report a detection technique using millimeter-wave interferometry based on sensitive

Archita Hati, Craig W. Nelson
Non-contact thermoacoustic imaging (TAI) has several desirable characteristics for applications such as explosive detection in high-water content media. In this paper, we report a detection technique using mm-wave interferometry based on sensitive phase

An Atom Probe Tomograph Incorporating a Wavelength-Tuneable Femtosecond-Pulsed Coherent Extreme Ultraviolet Light Source

June 19, 2019
Author(s)
Ann C. Chiaramonti Debay, Luis Miaja Avila, Paul T. Blanchard, David R. Diercks, Brian Gorman, Norman A. Sanford
Pulsed coherent extreme ultraviolet (EUV) radiation is a potential promising alternative to pulsed infra-red, visible, and near- ultraviolet laser sources for atom probe tomography. In addition to having the benefit of high absorption across the periodic

Bottom-up Gold Filling of High Aspect Ratio Trenches

June 19, 2019
Author(s)
Stephen J. Ambrozik, Thomas P. Moffat, Daniel Josell, Chen Zhang, Houxian Miao
This work demonstrates bottom-up superconformal Au filling of trenches as tall as seventeen micrometers. Deposition is conducted in a near-neutral Na3Au(SO3)2 + Na2SO3 electrolyte containing a micromolar concentration of Bi3+, known to accelerate the Au

Electron Doping BaZrO 3 via Topochemical Reduction

June 19, 2019
Author(s)
Thomas Orvis, Mythili Surendran, Yang Liu, Shanyuan Niu, Shinichiro Muramoto, Alexander Grutter, Jayakanth Ravichandran
We report the topochemical reduction of epitaxial thin films of the cubic perovskite BaZrO 3. Reduction with calcium hydride yields n-type conductivity in the films, despite the wide bandgap and low electron affinity of the parent material. X-ray

Measuring & Predicting Crystal Morphology in Fused Deposition Modeling

June 19, 2019
Author(s)
Claire McIlroy, Jonathan Seppala, Anthony Kotula
Semi-crystalline polymer melts are commonly used in fused deposition modeling. Although flows have a profound effect on polymer crystallization, the relationship between typical fused deposition modeling (FDM) deformation rates and printed-part crystal

Polymer Additive Manufacturing: Confronting Complexity

June 19, 2019
Author(s)
Anthony P. Kotula, Jonathan E. Seppala, Chad R. Snyder
Since its development and commercialization in the 1980s, polymer additive manufacturing (AM) has become a disruptive technology. In this chapter we describe the ever-increasing demands for polymer AM in industry, academia, and government, as well as the

Position- and Polarization-Specific Waveguiding of Multi-Emissions in Single ZnO Nanorods

June 19, 2019
Author(s)
Bonghwan Chon, Johnson Truong, Matthew Hansen, Jong-in Hahm, Young Jong Lee
We examine multiphoton-produced optical signals waveguided through single ZnO nanorods (NRs) using a newly developed, scanning offset-emission hyper- spectral microscopy (SOHM) technique. Specifically, we concurrently analyze waveguiding behaviors of sum

Pre-Fire and Post-Fire Data Studies in the WUI

June 19, 2019
Author(s)
Eric D. Link
Pre-Fire and Post-Fire Data Studies in the WUI are a systematic effort to document and understand the fire and ember exposure, and consequential damage, from a wildland fire which burned into a developed area. The purpose of such studies is to provide a

Attribute Considerations for Access Control Systems

June 18, 2019
Author(s)
Chung Tong Hu, David F. Ferraiolo, David Kuhn
Attribute-based access control systems rely upon attributes to not only define access control policy rules but also enforce the access control. Attributes need to be established, issued, stored, and managed under an authority. Attributes shared across

Estimating real-time infiltration for use in residential ventilation control

June 18, 2019
Author(s)
Lisa Ng, Stephen M. Zimmerman, Jeremy Good, Brian Tool, Steven Emmerich, Andrew Persily
Minimum outdoor air ventilation rates specified in standards such as ASHRAE Standard 62.2 are generally based on envelope airtightness, building floor area, geographical location, and number of occupants. To meet ventilation requirements in practice

Reducing Localization Error of Vision-Guided Industrial Robots

June 18, 2019
Author(s)
Marek Franaszek, Geraldine S. Cheok, Jeremy A. Marvel
In many manufacturing applications, such as automated drilling or inspection of large parts, accurate knowledge of both position and orientation is critical. In this paper, a method for reducing robot end-effector position and orientation error is

Spin Stripe Order in a Square Planar Trilayer Nickelate
