Influence of PA66 fiber content on porosity of porous aluminum based ceramic core
Cailiao gongcheng, 2020 In order to solve the problem that alumina based ceramic core is not easy to remove core, a certain amount of PA66 fiber was added as pore forming material to prepare porous aluminum based ceramic core by hot pressing. The influence of PA66 fiber content

International Journal of Adaptive Control and Signal Processing, EarlyView.This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
