UAV path planning based on improved Whale Optimization Algorithm in multi-obstacle scenarios

Abstract To address the issues of poor convergence performance and susceptibility to local optima in the traditional Whale Optimization Algorithm (WOA) for 3D path planning of unmanned aerial vehicles (UAVs), we propose an improved Whale Optimization Algorithm (R*WOA) that integr...

TPHH: a long-term (1901–2023) high-resolution (1∕30°) near-surface humidity dataset for the Tibetan Plateau generated via spatial downscaling based on hybrid-structure deep learning

The Tibetan Plateau acts as the “Asian Water Tower” and faces regional amplified warming compared to the global climate change baseline. Given the Tibetan Plateau's pronounced alpine terrain, i.e., significant elevation gradients within short horizontal distances, studies on clim...

Low-Light Micro-Vibration Sensing on Satellite Platforms via Physical Encoding Self-Supervised Learning

Micro-vibrations of satellite platforms can reduce the pointing accuracy of space optical communication links, leading to a reduction in link margin and even link interruption. Traditional methods rely on accelerometers to obtain vibration labels, leading to hardware deployment d...

Ultra-Short Hollow-Core Anti-Resonant Fiber Polarization Filter Covering C+L Band Based on SPR Effect

This paper proposes an ultra-short hollow-core anti-resonant fiber (HC-ARF) polarization filter covering the C+L communication band based on the surface plasmon resonance (SPR) effect. The structure consists of six composite tubes, each formed by nesting an elliptical cladding tu...

Location-private traffic flow prediction via an encrypted geometric recruitment framework

Accurate traffic flow prediction at specific road segments is essential for optimizing signal control, mitigating congestion, and improving the efficiency of urban transportation systems. Mobile Crowdsensing (MCS) enables large-scale monitoring by collecting geotagged data from p...
