Enhanced Road Crack Segmentation Using Self-Supervised Learning in Motion-Blurred Images
Abstract With the increasing deployment of autonomous inspection platforms [e.g., unmanned aerial vehicles (UAVs) and robots], the segmentation performance of learning-based road inspection methods is facing severe challenges due to motion blur. In response, an innovative image s...

Wingtip Vortex Statistics and Multiscale Evolution in Grid-Generated Turbulent Flow
Freestream turbulence (FST) exerts a pronounced influence on the evolution of wingtip vortices through interactions between multiscale vortex structures. In this study, the vortex statistics and multiscale dynamics of an isolated wingtip vortex subjected to three levels of FST ar...
