Sorry for the downtime

, 2006
OAN was down all night last night. I discovered and fixed the problem first thing this morning. Apparently my last upload yesterday got far enough to delete the old file but no further. My apologies, and curses to the FTP gremlins.

Fault Diagnosis in an Induction‐Motor‐Driven Rotating Machinery Test Rig Under Unseen Operating Loads Using Multimodal Fusion and Multiagent Deep Reinforcement Learning

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Conventional fault‐diagnosis methods, largely grounded in one‐dimensional signal analysis and linear modeling, often fail to detect complex nonlinear faults in rotating machinery operating under variable loads. Data‐driven approaches also face challenges in extracting discriminative information from high‐dimensional multisensor measurements ...

Machine Learning‐Assisted Optimization for Dynamic Supply Network Design in the Additive Manufacturing Platform

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Distributed manufacturing enabled by additive manufacturing (AM) allows supply chains to rapidly adapt to changing market conditions through flexible facility relocation and capacity adjustment. However, existing studies largely overlook the logistical aspects of AM‐based supply chains and typically treat facility location and logistics ...

Application of Non‐Isothermal Network Theory With Curved‐Channel Element Characteristics to Predict Melt Conveying in High‐Performance Single‐Screw Extruders

Journal of Polymer Science, EarlyView.
This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older

Recommendations to enhance neurodiversity inclusivity in field‐based learning in plant biology higher education

PLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Field‐based learning is an important component of plant biology higher education, offering students valuable hands‐on in situ experiences to help students appreciate and understand plants within their environment. This nature‐based learning may be particularly valuable for students with neurodiversity conditions who might ...

Weibull Variational Autoencoder for Remaining Useful Life Prediction

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Remaining useful life (RUL) prediction is a critical technology for preventing unexpected failures and reducing maintenance costs in modern industrial systems. However, traditional model‐based approaches are limited by the need for explicit mathematical modeling of degradation mechanisms, while data‐driven methods often require large‐scale ...
