The Discrete Adjoint Method for Exponential Integration
Kai Rothauge, Eldad Haber, Uri Ascher
The implementation of the discrete adjoint method for exponential time differencing (ETD) schemes is considered. This is important for parameter estimation problems that are constr…
A Framework for the Upscaling of the Electrical Conductivity in the Quasi-static Maxwell's Equations
Luz Angelica Caudillo-Mata, Eldad Haber, Lindsey J. Heagy +1
Electromagnetic simulations of complex geologic settings are computationally expensive. One reason for this is the fact that a fine mesh is required to accurately discretize the el…
An oversampling technique for the multiscale finite volume method to simulate electromagnetic responses in the frequency domain
Luz Angelica Caudillo Mata, Eldad Haber, Christoph Schwarzbach
In order to reduce the computational cost of the simulation of electromagnetic responses in geophysical settings that involve highly heterogeneous media, we develop a multiscale fi…
A fast marching algorithm for the factored eikonal equation
Eran Treister, Eldad Haber
The eikonal equation is instrumental in many applications in several fields ranging from computer vision to geoscience. This equation can be efficiently solved using the iterative…
Joint Hydrogeophysical Inversion: State Estimation for Seawater Intrusion Models in 3D
K. Steklova, E. Haber
Seawater intrusion (SWI) is a complex process, where 3D modeling is often necessary in order to monitor and manage the affected aquifers. Here, we present a synthetic study to test…
Full waveform inversion guided by travel time tomography
Eran Treister, Eldad Haber
Full waveform inversion (FWI) is a process in which seismic numerical simulations are fit to observed data by changing the wave velocity model of the medium under investigation. Th…
