NOVEL ZIRCONIA MATERIALS IN DENTISTRY

October 16, 2017
Author(s)
Yu Zhang, Brian R. Lawn
Zirconias, the most durable of the dental ceramics, are increasingly being fabricated in monolithic form for a range of clinical applications, circumventing issues associated with weak porcelain veneers. Yttria-based tetragonal zirconia polycrystal (Y-TZP)

Integrated Optical Waveguides for in situ Microflow Measurements

October 15, 2017
Author(s)
James R. Hands, Gregory A. Cooksey
The need for quantitative microscale chemical and biological experiments has resulted in the increasing utilization of microfluidics with integrated sensors, allowing such architectures to synergistically enhance function and performance [1]. This work

Serial Robotic Arm Joint Characterization Measurements for Antenna Metrology

October 15, 2017
Author(s)
Michael S. Allman, David R. Novotny, Joshua A. Gordon, Alexandra Curtin, Scott Sandwith
We developed an accurate kinematic model of our six-axis serial robotic arm used for antenna characterization measurements. The model was calibrated over a 0.4 m3 working cell. We validated the calibration using a 1 m2 plane embedded within the calibration

Channel De-embedding and Measurement System Characterization for MIMO at 75 GHz

October 14, 2017
Author(s)
Alexandra Curtin, David R. Novotny, Alex Yuffa
Abstract—We explore the development of a sparse set of measurements for array calibration, relying on coherent multi- channel data acquisition of wideband signals at 75 GHz, and the hardware characterization and post-processing necessary to perform channel

Observation of spin-orbit effects with spin rotation symmetry

October 13, 2017
Author(s)
Alisha Humphries, Tao Wang, Eric R. Edwards, Shane Allen, Justin Shaw, Hans Nembach, John Xiao, Thomas J. Silva
The spin-orbit interaction in a nonmagnetic/magnetic multilayer has been intensively studied due to its efficient conversion between a spin current and a charge current. In the spin Hall/Rashba-Edelstein effects (SHE/REE) and inverse spin Hall/Rashba

A Multistate Single-Connection Calibration for Microwave-Microfluidics

October 12, 2017
Author(s)
Xiao Ma, Charles A. Little, Chris Long, Jordi Mateu, James Booth, James Hwang, Nate Orloff
With emerging medical, chemical, and biological applications of microwave-microfluidic devices, many researchers desire a fast, accurate calibration that can be achieved in a single connection. However, traditional on-wafer or coaxial calibrations require

Applying Measurement Science to Evaluate Ground, Aerial, and Aquatic Robots

October 12, 2017
Author(s)
Adam S. Jacoff, Rick Candell, Anthony Downs, Hui-Min Huang, Kenneth Kimble, Kamel Saidi, Ann Virts
This paper reports on three measurement science field exercises for evaluating ground, aerial, and aquatic robots. These events, conducted from February to June 2017, were conducted in close co-ordination with the responder community, standards

Cloud Security Automation Framework

October 12, 2017
Author(s)
Cihan Tunc, Salim hariri, Mheni Merzouki, Charif Mahmoudi, Frederic J. de Vaulx, Jaafar Chbili, Robert B. Bohn, Abdella Battou
Cloud services have gained tremendous attention as a utility paradigm and have been deployed extensively across a wide range of fields. However, Cloud security is not catching up to the fast adoption of its services and remains one of the biggest
