Characterization of Nitinol Produced by Laser Powder Bed Fusion for Mechanical Metamaterial Applications

open access: yesAdvanced Engineering Materials, EarlyView.
Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Tail asymptotics of signal-to-interference ratio distribution in spatial cellular network models

open access: yes, 2017
We consider a spatial stochastic model of wireless cellular networks, where the base stations (BSs) are deployed according to a simple and stationary point process on $\mathbb{R}^d$, $d\ge2$.

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

A Path Loss Model for Non-Line-of-Sight Ultraviolet Multiple Scattering Channels

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
An ultraviolet (UV) signal transmission undergoes rich scattering and strong absorption by atmospheric particulates. We develop a path loss model for a Non-Line-of-Sight (NLOS) link.

The disease mutation A77V in Ryanodine receptor RyR2 induces changes in energy conduction pathways in the protein [PDF]

open access: yes, 2011
Energetically responsive residues of the 217 amino acid N-terminal domain of the cardiac Ryanodine receptor RyR2 are identified by a simple elastic net model. These residues lie along a hydrogen bonded path through the protein.

A Tractable Model for Non-Coherent Joint-Transmission Base Station Cooperation

open access: yes, 2014
This paper presents a tractable model for analyzing non-coherent joint transmission base station (BS) cooperation, taking into account the irregular BS deployment typically encountered in practice.

Further investigation of empirical path-loss modeling for short forested paths

open access: yesProceedings of the 2012 IEEE International Symposium on Antennas and Propagation, 2012
This paper reports an experimental study of path-loss modeling in foliage environments for VHF and UHF short-range applications. Through the investigation, it is found that although the path loss in a forest can be conveniently modeled using linear regression, it is difficult to apply the extracted information to other forests due to the variety of ...

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

open access: yesAdvanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Downlink Analysis for a Heterogeneous Cellular Network

open access: yes, 2014
In this paper, a comprehensive study of the the downlink performance in a heterogeneous cellular network (or hetnet) is conducted. A general hetnet model is considered consisting of an arbitrary number of open-access and closed-access tier of base ...
