Global and Partial Phase Synchronizations in Arrays of Piecewise Linear Time-Delay Systems

, 2012
In this paper, we report the identification of global and partial phase synchronizations in linear arrays of unidirectionally coupled piecewise linear time-delay systems with two different coupling configurations.

Phase‐Change Solvents for Thermally Switchable Ion Conduction in Organogels

Advanced Materials, EarlyView.
Organogels containing salts dissolved in phase‐change solvents exhibit thermally switchable ion conduction. The organogels, which display an over 10 000‐fold on‐off ratio and high cycling stability, can be synthesized with a wide range of salts and customizable conductivity/temperature relations for applications in ionotronics and energy storage ...

Real‐time emission and cost estimation based on unit‐level dynamic carbon emission factor

Energy Conversion and Economics, 2023
The real‐time carbon emission estimation of generators helps quantify the carbon emission costs and reduce power system emissions of power generation. Accurate estimation relies on the accuracy of the carbon emission factors (EFs) and power generation ...

Mixed-Mode Oscillations in a Stochastic, Piecewise-Linear System

, 2010
We analyze a piecewise-linear FitzHugh-Nagumo model. The system exhibits a canard near which both small amplitude and large amplitude periodic orbits exist.

Recent Progress on Flexible Multimodal Sensors: Decoupling Strategies, Fabrication and Applications

Advanced Materials, EarlyView.
In this review, we establish a tripartite decoupling framework for flexible multimodal sensors, which elucidates the underlying principles of signal crosstalk and their solutions through material design, structural engineering, and AI algorithms. We also demonstrate its potential applications across environmental monitoring, health monitoring, human ...

Square-mean piecewise almost automorphic mild solutions to a class of impulsive stochastic evolution equations

Advances in Difference Equations, 2020
In this paper, we introduce the concept of square-mean piecewise almost automorphic function. By using the theory of semigroups of operators and the contraction mapping principle, the existence of square-mean piecewise almost automorphic mild solutions ...

Learning of Continuous and Piecewise-Linear Functions With Hessian Total-Variation Regularization

IEEE Open Journal of Signal Processing, 2022
We develop a novel 2D functional learning framework that employs a sparsity-promoting regularization based on second-order derivatives. Motivated by the nature of the regularizer, we restrict the search space to the span of piecewise-linear box splines ...

Piecewise-linear-basis-function expansions

Electronics Letters, 1973
A new method of representing a signal using piecewise-linear basis functions has been described. The letter provides a very simple method of determining the expansion coefficients as linear combinations of samples of the signal.

Pattern Formation in Non‐Equilibrium Architected Materials

Advanced Materials Technologies, EarlyView.
This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.
