Execution-Consistent Event-Responsive Truck–UAV Coordination Under Simulated Progressive Road Disruption

Progressively revealed road disruptions can invalidate truck–unmanned aerial vehicle (UAV) relief plans while deliveries and recovery operations are already under way. We develop ER-HLNS-PR, an event-responsive framework that reconciles realized task, vehicle, and material states...

Rapid Epicentral Distance and Magnitude Estimation via Collaborative Attention Network

ABSTRACT Rapid and reliable estimation of epicentral distance and magnitude are pivotal for damage assessment in earthquake early warning (EEW). However, conventional epicentral distance and magnitude estimation approaches for EEW rely primarily on manually defined features to co...

Pitting corrosion inversion of buried pipelines based on weak magnetic detection and interpretable SACCO-ELM

Buried pipelines play an important role in long-distance energy transportation. However, buried pipelines are prone to pitting corrosion due to harsh soil environment, making quantitative pitting corrosion inversion critical for safety. This paper proposes an interpretable invers...

Service-continuity-oriented assessment and closed-loop governance of compound flood-season risk at a piedmont hospital in Beijing

Abstract Healthcare facilities in piedmont transition zones can be exposed simultaneously to slope instability, hillslope runoff, local waterlogging, access disruption, and lifeline failures during extreme rainfall. This study examines a specialized kidney hospital in Beijing and...

Analysis of Smoke-Spread Characteristics in Electric Vehicle Fires in a Two-Lane Tunnel with an Arched Ceiling

With the rapid increase in electric vehicle ownership, fire risks associated with electric vehicles in tunnels have attracted increasing attention. In this study, a numerical model of an electric vehicle fire in a two-lane tunnel with an arched ceiling was established using the F...

A Saturation-Constrained Four-Phase Acoustic Screening Model for Shallow Gas-Bearing Permafrost: Coupled Effects of Ice Cementation, Gas Saturation, and Pore Pressure

Shallow free gas trapped within or beneath polar permafrost can be destabilized by drilling-induced thermal and pressure perturbations, but its acoustic response is difficult to separate from variations in lithology and freezing state. This study develops a saturation-constrained...

Structural performance of offshore wind turbines under wind and seafloor ground motions using a coupled seismic-aerodynamic analysis method

This study proposes a fully coupled seismic-aerodynamic analysis method of offshore wind turbines (OWT) through the modular coupling and bidirectional data exchange, which integrates synthesized seafloor ground motions, steel damage evolution model, and soil-structure interaction...

Surface Roughness and Chemical Weathering of Fluvial Geomorphic Surfaces: A Case Study from Qingyi River, Eastern Tibetan Plateau

River terraces and alluvial fans preserve important records of landscape evolution, yet establishing their relative chronology is often difficult where suitable materials for numerical dating are scarce. This study explores whether geomorphic-surface roughness and sediment chemic...
