GNS: A generalizable Graph Neural Network-based simulator for particulate and fluid modeling
Krishna Kumar, Joseph Vantassel
We develop a PyTorch-based Graph Network Simulator (GNS) that learns physics and predicts the flow behavior of particulate and fluid systems. GNS discretizes the domain with nodes…
DAS for 2D MASW Imaging: A Case Study on the Benefits of Flexible Sub-Array Processing
Michael B. S. Yust, Brady R. Cox, Joseph P. Vantassel +1
Distributed acoustic sensing (DAS) is a relatively new technology for recording stress wave propagation, with promising applications in both engineering and geophysics. DAS's abili…
Mapping Depth to Bedrock, Shear Stiffness, and Fundamental Site Period at CentrePort, Wellington using Surface Wave Methods: Implications for Local Seismic Site Amplification
Joseph P. Vantassel, Brady R. Cox, Liam Wotherspoon +1
Wellington's port (CentrePort) experienced significant damage from the 7.8 Kaikōura earthquake as a result of soil liquefaction, lateral spreading, and shaking-induced damage…
A Frequency-Velocity CNN for Developing Near-Surface 2D Vs Images from Linear-Array, Active-Source Wavefield Measurements
Aser Abbas, Joseph P. Vantassel, Brady R. Cox +2
This paper presents a frequency-velocity convolutional neural network (CNN) for rapid, non-invasive 2D shear wave velocity (Vs) imaging of near-surface geo-materials. Operating in…
Minority Report: A Graph Network Oracle for In Situ Visualization
Krishna Kumar, Paul Navrátil, Andrew Solis +1
In situ visualization techniques are hampered by a lack of foresight: crucial simulation phenomena can be missed due to a poor sampling rate or insufficient detail at critical time…
Extracting High-Resolution, Multi-Mode Surface Wave Dispersion Data from Distributed Acoustic Sensing Measurements using the Multichannel Analysis of Surface Waves
Joseph P. Vantassel, Brady R. Cox, Peter G. Hubbard +1
We rigorously assess the potential for extracting high-resolution, multi-mode surface wave dispersion data from distributed acoustic sensing (DAS) measurements using active-source…
