Reliable H∞ filtering for discrete time-delay systems with randomly occurred nonlinearities via delay-partitioning method [PDF]

, 2011
The official published version can be found at the link below.In this paper, the reliable H∞ filtering problem is investigated for a class of uncertain discrete time-delay systems with randomly occurred nonlinearities (RONs) and sensor failures. RONs are

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Oscillation Criteria of Higher-order Neutral Differential Equations with Several Deviating Arguments

Mathematics, 2020
This work is concerned with the oscillatory behavior of solutions of even-order neutral differential equations. By using the technique of Riccati transformation and comparison principles with the second-order differential equations, we obtain a new ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

Advanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Razumikhin-type theorem for neutral stochastic functional differential equations with unbounded delay

, 2011
This paper establishes the Razumikhin-type theorem on stability for neutral stochastic functional differential equations with unbounded delay. To overcome difficulties from unbounded delay, we develop several different techniques to investigate stability.

Oscillations Of Systems Of Neutral Delay Parabolic Equations

Demonstratio Mathematica, 1998
The authors use an averaging technique in order to obtain oscillation criteria for the solutions of the systems of neutral delay parabolic equations \[ \begin{multlined} {\partial\over\partial t}[U_i(x,t)- b(t) U_i(x,t-\gamma)]= a_i(t)\Delta U_i(x,t)+ \sum^s_{j=1} a_{ij}(t)\Delta U_k(x,t- \tau_j)- p_i(x, t)U_i(x,t)-\\ \sum^m_{k=1} \sum^l_{h=1} \int^b_a

Current Decoupling and Controller Design for Induction Motors Based on Neutral Delay System

MATEC Web of Conferences, 2019
In the AC power transmission system, in order to reduce the loss of switching devices, the switching frequency of the traction converter is generally low, and a large digital control delay will occur, which will aggravate the cross coupling between the ...
