Reading the forest through patents: A Europe-wide sector analysis

Innovation will shape how Europe's Forest sector responds to growing demand for low-carbon materials and bio-based products. However, the technological composition and geographical distribution of recent patenting activity in the sector remain insufficiently documented. This stud...

A battery life prediction method based on graph neural network assisted by deep reinforcement learning

With the wide utilization of new energy batteries, the accurate prediction of battery life has become an urgent technical issue that needs to be addressed. Studies have developed battery life prediction models based on correlation analysis for feature extraction. This study intro...

Numerical Generation of Mode I Stress Intensity Factors for Narrow Elliptical Cracks in Round Bars

ABSTRACT Linear elastic fracture mechanics (LEFM) allows for the analysis of crack propagation by combining remote stress fields in the solid with stress intensity factors (SIFs) obtained for specific crack configurations. To date, the use of tabulated SIFs has greatly facilitate...

Challenges in integrating sustainability into Overall Equipment Effectiveness (OEE): a trade-off-based Roadmap

Abstract Integrating operational excellence with sustainable performance has become a key priority in manufacturing systems. However, traditional performance metrics remain limited in their ability to capture sustainability dimensions. This study employs a systematic literature r...

Structure-property relationships in biopolyurethane/acrylate hybrid films: Role of chain extender and acrylic content

Waterborne polyurethane/acrylic (PU/AC) hybrid dispersions are widely used in coatings applications due to their low environmental impact and tailorable thermomechanical performance, and are typically composed of particles with a core-shell morphology. Controlling phase morpholog...
