Velocity Reconstruction from Flow-Induced Magnetic Fields

Yacine Mokhtari, Christina Frederick, Yunan Yang +1

We study the inverse problem of reconstructing an incompressible velocity field $v$ from observations of the induced magnetic field $b$ . In the presence o…

Numerical methods for multiscale inverse problems

Christina Frederick, Bjorn Engquist

We consider the inverse problem of determining the highly oscillatory coefficient $a^{ε}$ in partial differential equations of the form $- \nabla \cdot (a^{ε} \nabla u^{ε}) + b u^{ε} = f$ from gi…
