Transdimensional 2D Full-Waveform Inversion and Uncertainty Estimation
Reetam Biswas, Mrinal K. Sen
Full-Waveform Inversion (FWI) has now become a widely accepted tool to obtain high-resolution velocity models from seismic data. Typically, the velocity model in its discrete form…
Accelerating Least Squares Imaging Using Deep Learning Techniques
Janaki Vamaraju, Jeremy Vila, Mauricio Araya-Polo +3
Wave equation techniques have been an integral part of geophysical imaging workflows to investigate the Earth's subsurface. Least-squares reverse time migration (LSRTM) is a linear…
Finite Difference Based Wave Simulation in Fractured Porous Rocks
Janaki Vamaraju, Mrinal K. Sen
Biot's theory provides a framework for computing seismic wavefields in fluid saturated porous media. Here we implement a velocity-stress staggered grid 2D finite difference algorit…
A stabilized radial basis-finite difference (RBF-FD) method with hybrid kernels
Pankaj K Mishra, Gregory E Fasshauer, Mrinal K Sen +1
Recent developments have made it possible to overcome grid-based limitations of finite difference (FD) methods by adopting the kernel-based meshless framework using radial basis fu…
On the idempotent semirings such that is the least distributive lattice congruence
M. K. Sen, A. K. Bhuniya, R. Debnath
Here we describe the least distributive lattice congruence on an idempotent semiring in general and characterize the varieties and of all ide…
An improved radial basis-pseudospectral method with hybrid Gaussian-cubic kernels
Pankaj K Mishra, Sankar K Nath, Gregor Kosec +1
While pseudospectral (PS) methods can feature very high accuracy, they tend to be severely limited in terms of geometric flexibility. Application of global radial basis functions o…
Hybrid Gaussian-cubic radial basis functions for scattered data interpolation
Pankaj K Mishra, Sankar K Nath, Mrinal K Sen +1
Scattered data interpolation schemes using kriging and radial basis functions (RBFs) have the advantage of being meshless and dimensional independent, however, for the data sets ha…
A study on the effect of age, gender and paralysis on sEMG signals
Abhishek Jha, Mrinal Sen
Surface Electromyography (sEMG) is a technology to measure the bio-potentials across the muscles. The true prospective of this technology is yet to be explored. In this paper, a si…
