Effect of Adjacent Hydrophilic Polymer Thin Films on Physical Aging and Residual Stress in Thin Films of Poly(butylnorbornene-ran-hydroxyhexafluoroisopropyl norbornene)

June 22, 2019
Author(s)
Elizabeth A. Lewis, Christopher Stafford, Bryan D. Vogt
The properties of thin supported polymer films can be dramatically impacted by the substrate upon which it resides. A simple way to alter the properties of the substrate (chemistry, rigidity, dynamics) is by coating it with an immiscible polymer. Here we

An Implementation Proposal for IEEE 802.11ay SU/MU-MIMO Communication in ns-3

Structural characterization and X-ray reference powder pattern determination have been condcuted for the Co- and Zn-containing tridymite derivatives Ba(Co1-xZnx)SiO4 (x = 0.2, 0.4, 0.6, 0.8). The bright blue series of Ba(Co1-xZnx)SiO4 crystallized in the

Decision Support for Smart Grid: Using Reasoning to Contextualize Complex Decision Making

June 20, 2019
Author(s)
Edward R. Griffor, David A. Wollman, Patrick Kamongi, Claire Vishik, Michael Huth, Marcello Balduccini
The smart grid is a complex cyber-physical system (CPS) that poses challenges related to scale, integration, interoperability, processes, governance, and human elements. The US National Institute of Standards and Technology (NIST) and its government

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
