Shape sensing with iFEM on a type IV pressure vessel based on experimental measurements

e-Journal of Nondestructive Testing
The service life of a ship depends on its structural integrity, which can be undermined through time via different loading conditions. The incorporation of a Structural Health Monitoring (SHM) system could enhance the safety of the vessel because information about its health condition could potentially lead to the avoidance of catastrophic scenarios ...

Balancing Feature Symmetry: IFEM-YOLOv13 for Robust Underwater Object Detection Under Degradation

Symmetry
This paper proposes IFEM-YOLOv13, a high-precision underwater target detection method designed to address challenges such as image degradation, low contrast, and small target obscurity caused by light attenuation, scattering, and biofouling. Its core innovation is an end-to-end degradation-aware system featuring: (1) an Intelligent Feature Enhancement ...
