Uncertainty‐Quantified Primary Particle Size Prediction in Li‐Rich NCM Materials via Machine Learning and Chemistry‐Aware Imputation

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
This study demonstrates a machine learning framework that predicts the primary particle size of Lithium‐rich Nickel‐Cobalt‐Manganese (Li‐rich NCM) materials from synthesis conditions, even with incomplete literature data. By combining chemistry‐aware imputation with uncertainty‐quantified modeling, it identifies sintering temperature and time as ...

Optimal Design of One-Sided Exponential EWMA Charts With Estimated Parameters Based on the Median Run Length

open access: yesIEEE Access, 2019
One-sided exponential exponentially weighted moving average (EWMA) charts are useful tools for monitoring high-quality processes. Average run length ($ARL$ ) is usually used as the only criterion to evaluate the performance of a control chart.
