Bayesian finite element model updating based on Markov chain population competition

Jixie qiangdu
The traditional Markov chain Monte Carlo(MCMC） simulation method is inefficient and difficult to converge in high dimensional problems and complicated posterior probability density.In order to overcome these shortcomings, a Bayesian finite element model ...

Finite Element Modelling and Model Updating of Riveted Joint Structure

Journal of Physics: Conference Series, 2019
Abstract Nowadays, the applications of rivet joints are dramatically increasing because of its capability and efficiency to assemble the engineering structure such as aerospace and mechanical structures. However, every joint such as riveted joint has a significant effect to the overall dynamic behaviour of the assembled structure.

In Situ Integrated Titanium Oxide Synaptic Phototransistor Enabling Multimodal Plasticity and Noise‐Robust Selective Attention

Advanced Materials Technologies, EarlyView.
An in situ integrated TiO2/SiOx/Al2O3 synaptic phototransistor couples ultraviolet and electrical stimuli within a scalable, CMOS‐compatible oxide stack. Multimodal plasticity, spike‐timing‐dependent learning, and bee‐inspired associative conditioning are achieved through trap‐mediated temporal dynamics.
