A novel 1D iFEM framework for structural health monitoring under degrading boundary conditions

The inverse finite element method (iFEM) reconstructs full-field displacements from strain data without prior knowledge of loads or material properties. However, unknown or time-varying boundary conditions can degrade shape-sensing accuracy.

Robust Image Watermarking via Clustered Visual State-Space Modeling

Applied Sciences
Most existing DNN-based image watermarking methods adopt an “encoder–noise–decoder” paradigm, where the watermark is typically replicated and expanded in a straightforward manner and then directly fused with image features, which limits robustness under ...
