A First realization of ASTM E3125-17 test procedures for laser scanner performance evaluation

February 1, 2020
Author(s)
Ling Wang, Balasubramanian Muralikrishnan, Vincent D. Lee, Prem K. Rachakonda, Daniel S. Sawyer, Joe Gleason
Spherical coordinate three-dimensional (3D) imaging systems, such as Terrestrial Laser Scanners (TLS), are already used widely in different fields. Their measurement performance evaluation is a topic of active research. In 2017, the first comprehensive

Alignment of Worm-like Micelles at Intermediate and High Shear Rates

February 1, 2020
Author(s)
Brisa Arenas-Gomez, Cristina Garza, Yun Liu, Rolando Castillo
Hypothesis. Rheology combined with Small Angle Neutron Scattering (Rheo-SANS) can determine the local structural order in Worm-like Micelle (WLM) solutions, when the shear rate increases beyond the ending of the gradient shear banding, where the micellar

Emergent Electric Field Control of Phase Transformation in Oxide Superlattices

February 1, 2020
Author(s)
Di Yi, Yujia Wang, Olaf M. J. van t'Erve, Liubin Xu, Hongtao Yuan, Michael J. Veit, Purnima P. Balakrishnan, Yongseong Choi, Alpha T. N'Diaye, Padraic Shafer, E. Arenholz, Alexander Grutter, Haixuan Xu, Pu Yu, Berend T. Jonker, Yuri Suzuki
Electric fields have been shown to transform materials with respect to their structure and properties, thus enabling many applications ranging from batteries to spintronics. Recently electrolytic gating, which can generate large electric fields and voltage

Field-Only Surface Integral Equations: Scattering from a Dielectric Body

February 1, 2020
Author(s)
Qiang Sun, Evert Klaseboer, Alex Yuffa, Derek Y. Chan
An efficient field-only nonsingular surface integral method to solve Maxwell's equations for the components of the electric field on the surface of a dielectric scatterer is introduced. In this method, both the vector wave equation and the divergence-free

Field-Only Surface Integral Equations: Scattering from a Perfect Electric Conductor

February 1, 2020
Author(s)
Qiang Sun, Evert Klaseboer, Alex Yuffa, Derek Y. Chan
A field-only boundary integral formulation of electromagnetics is derived without the use of surface currents that appear in the Stratton--Chu formulation. For scattering by a perfect electrical conductor (PEC), the components of the electric field are

Leveraging Side-channel Information for Disassembly and Security

February 1, 2020
Author(s)
JUNGMIN Park, Fahim Rahman, Apostol Vassilev, Domenic Forte, Mark Tehranipoor
With the rise of Internet of Things (IoT), devices such as smartphones, embedded medical devices, smart home appliances as well as traditional computing platforms such as personal computers and servers have been increasingly targeted with a variety of

Methods to calibrate a three-sphere scale bar for laser scanner performance evaluation per the ASTM E3125-17

February 1, 2020
Author(s)
Ling Wang, Balasubramanian Muralikrishnan, Vincent D. Lee, Prem K. Rachakonda, Daniel S. Sawyer, Joe Gleason
A scale bar with sphere targets is one way of realizing the symmetric and asymmetric length tests to evaluate terrestrial laser scanner (TLS) performance per the ASTM E3125-17 standard. The length of the scale bar is required to be known with an expanded

Moment subset sums over finite fields

February 1, 2020
Author(s)
Tim LAI, Alicia Marino, Angela Robinson, Daqing Wan
The k-subset sum problem over finite fields is a classical NP-complete problem. Motivated by coding theory applications, a more complex problem is the higher m-th moment k-subset sum problem over finite fields. We show that there is a deterministic

Pressure-Thresholded Response in Cylindrically Shocked Cyclotrimethylene Trinitramine (RDX)

February 1, 2020
Author(s)
Leora E. Dresselhaus-Cooper, Dmitro Martynowych, Fan Zhang, Charlene Tsay, Jan Ilavsky, SuYin Wang, Yu-Sheng Chen, Lara Leininger, Keith A. Nelson
We demonstrate a strongly thresholded response in cyclotrimethylene trinitramine (RDX) that is cylindrically shocked using a novel waveguide geometry. Using ultrafast single-shot multi-frame imaging, we demonstrate that a 100-μm diameter single crystal of
