Design of Lunar Soil Simulant for Lunar Landing Applications and Its Mechanical Property Evolution under Impact Loading

This study develops a Changbai Mountain volcanic ash-based lunar soil simulant tailored for the Moon's far side and South Pole, demonstrating through impact tests on various slopes that landing gradients significantly alter the spatial distribution of post-impact mechanical properties, with shear strength weakening uphill and strengthening downhill until stabilizing beyond 8°.

Activation-Grade-Scheduled Predictive Control for Battery–Supercapacitor Electric-Vehicle Energy Management

This paper proposes an activation-grade-scheduled predictive controller with a candidate-screening extension (M6) for battery–supercapacitor electric vehicles that successfully eliminates supercapacitor reserve depletion violations but introduces a trade-off by increasing battery current stress and DC-link voltage errors compared to conventional fixed-weight control.

Elastic Strain Energy Redistribution and Ground Control through Large Diameter Borehole Pressure Relief in a Coal Roadway under Intense Mining Disturbance

This study utilizes numerical simulations and field monitoring to demonstrate that optimizing large-diameter borehole pressure relief parameters (specifically diameter, depth, and spacing) in conjunction with advanced support systems effectively redistributes elastic strain energy and significantly reduces roadway convergence in coal mines under intense mining disturbance.

A Hierarchical Stochastic Decision-Making Framework for Task Scheduling and Safety-Aware Human-Robot Collaboration

This paper proposes a hierarchical stochastic decision-making framework that integrates an upper-level Markov decision process for urgency- and fatigue-aware task scheduling with a lower-level partially observable Markov decision process for safety-oriented execution, enabling fast, coordinated human-robot collaboration through precomputed policies and bidirectional information exchange.

Assessment of Recycled Brick and Concrete Aggregate as Filter Media for Laundry Wastewater Treatment for Irrigation Purposes

This study demonstrates that recycled broken brick aggregate, particularly at a 900 mm bed depth, serves as a chemically stable and low-cost filter media for effectively treating laundry greywater to meet irrigation standards in resource-constrained settings, outperforming crushed concrete by avoiding the leaching of calcium and elevating pH, EC, and TDS levels.

Thermal-history and morphology-conditioned multimodal fusion for robotic MAG weld-quality classification

The authors propose HMCF-Net, a multimodal fusion network that enhances robotic MAG weld-quality classification accuracy by jointly conditioning visual, electrical, and acoustic features on calculated thermal history and explicit pool geometry descriptors, achieving 94.72% accuracy without requiring direct temperature measurements or extended observation windows.

Evaluating a post-incident drinking water quality monitoring network using consumer complaints and verified leak events​​

This study evaluates Incheon's post-incident drinking water monitoring network and finds that while high-frequency sensors successfully detected network-wide disturbances before consumer complaints peaked, their strategic placement was misaligned with local problem areas, covering only 16% of the complaint burden compared to a potential 89% if stations had been sited based on historical complaint data.
