Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Hybrid Filters To Damp Harmonic Resonance In Power Transmission Systems
Eletrônica de Potência, 2006 Problems related to harmonic propagation in transmission systems have been noticed in the last years. Passive filters, commonly used to attenuate noncharacteristic harmonics in HVDC systems, stay at risk of disconnection from the system due to ...

Adaptive Filter and Resonant Controller Applied to Hybrid Series Active Power Filter [PDF]
, 2012 This paper proposes a control strategy for Hybrid Active Series Power Filter (HASPF) based on a P+Resonant compensator. The proposed control uses Adaptive Notch Filter to isolate the harmonic content of the source current and a P+Resonant regulator to calculate the harmonic voltage signal necessary to properly tune the hybrid branch.

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.
