Seismic velocity models are effective for imaging subsurface structures, yet resolving shallow features at depths less than 100 m remains challenging due to the limited availability of high-frequency signals and the need for closely spaced channels. We addressed this using distributed acoustic sensing (DAS) to image...

Predicting underwater acoustic transmission loss rapidly and accurately is crucial for real-time ocean acoustic applications. While Fourier Neural Operators (FNO) have emerged as powerful surrogate models due to their global receptive fields, they suffer from spectral bias. The frequency truncation mechanism in FNO fil...

This work proposes GRAW, an adversary system, acting as a privacy defender, that degrades the human activity recognition (HAR) system at the user device by perturbing the router's signals that the device uses to estimate CSI.

This work presents real-world experimental results from a Bayesian underwater simultaneous localization and mapping (SLAM) system deployed on a remotely operated vehicle (ROV) and evaluated in both controlled pool experiments and ocean settings. The SLAM system uses a feature-based visual SLAM approach that extracts re...
