The Full Waveform Acoustic Log Inversion Problem [PDF]

, 1985
This paper presents the full waveform acoustic log inversion problem for a multisource - multireceiver tool logging a cylindrical fluid-filled borehole. The problem is formulated in the frequency-depth domain. A priori knowledge about the source array

Geometry‐Encoded Soft Strain Sensing via Liquid‐Metal Transmission Lines

Advanced Science, EarlyView.
This study presents a liquid‐metal transmission‐line strain sensor that achieves intrinsic decoupling by encoding axial elongation into propagation delay. The time‐domain readout remains stable under complex off‐axis. This enables reliable, repeatable, real‐time elongation measurement in dynamic, multiaxial loading environments for wearable electronics,

WaveInsight: A Source-Independent Full Waveform Inversion Application for Seismic Modeling

JGEET: Journal of Geoscience, Engineering, Environment and Technology
Full Waveform Inversion (FWI) is a key method in seismic exploration due to its ability to generate high-resolution subsurface velocity models. However, its success is highly dependent on the accuracy of the source wavelet, an incorrect wavelet ...

Closing the Loop: High‐Precision 3D Photofabrication in Living Tissues

Advanced Science, EarlyView.
Writing 3D microstructures inside living tissue demands more than laser access; It demands information. Hierarchical sensing captures thermal and mechanical states across pulse‐train, voxel, and structure timescales, feeding a controller that steers the laser in real time.

Ambient noise full waveform inversion for noise source distribution

, 2018
We use full waveform inversion of ambient noise to estimate noise source distributions and model parameters. We derive the sensitivity kernel with respect to a noise source distribution from ambient noise data.

Bio‐Inspired Internal Stress Engineering for Microscale Surface Cracking in Sensitive Strain Sensors

Advanced Science, EarlyView.
This study presents a bio‐inspired internal stress engineering strategy to fabricate highly sensitive crack‐based strain sensors. By harnessing the internal expansion energy of microspheres and the thickness‐dependent brittle‐to‐ductile transition of ultrathin gold films, tunable microscale cracks are generated.
