Abstract The rapid growth of event‐based social networks (EBSNs) has generated great demand for personalized event recommendation. Indeed, new events are published every day in EBSNs. In this paper, we focus on the problem recommending (i.e., newly that have not yet received any user response) to registered users Notice collaborative filtering is ineffective due short lifetime and lack historical information, is, cold‐start problem. A straightforward approach address adopt content‐based...
The electrocaloric effect represents an adiabatic temperature change or isothermal entropy upon the application removal of external electric field. However, repetitive bipolar/unipolar field on in ferroelectrics is not well understood. In this work, after both bipolar and unipolar electrical cycling Pb0.92La0.08Zr0.65Ti0.35O3 relaxor thin films has been indirectly evaluated using Maxwell relationship. It was found that at room temperature, ΔT under higher fields decreases gradually from a...
As the Ubiquitous Power Internet of Things (UPIoT) is being developed, data volume collected by various terminals such as smart electricity meters increasing daily. The efficient extraction information from massive and provision value-added services to users, power grids, market entities are crucial aspects research directions. A analysis application framework for meter based on cloud-fog computing contextualization established, a model three-dimensional (3d) maturity industrial users...
Electromechanical resonances of ceramic multilayer capacitors are calculated mechanically free and clamped boundary conditions using vibration piezoelectric equations. BaTiO/sub 3/-based Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub have been used to check the theoretical calculation. Frequency spectra impedance phase angle, capacitance, loss tangent under DC bias fields were carefully measured. A sudden change around resonant frequency is observed in these spectra. damped resonance indicates a defective...
Abstract In this paper, we propose a defect detection method based on YOLOv5 for thermal images of high-voltage insulators, in which large number insulator photographs are taken by imager, followed model to detect the captured images. The function Meta-ACON is proposed replace original activation function. Finally, extracted features used condition identification and detection. Experimental findings demonstrate efficacy suggested approach successfully accomplishing feature extraction faults,...
