Abstract: We develop three-dimensional electromagnetic inverse scattering methods to reconstruct buried objects in layered media. The nonlinear inverse problem is solved iteratively via conjugate gradient approach; within each iteration, the problem is linearized by Born and Distorted Born approximations. The forward solution for layered media is provided by the stabilized biconjugate-gradient ...

Multi-level transactions are a variant of open nested transactions in which the subtransactions correspond to operations at different levels of a layered system architecture. The point of multi-level transactions is that the semantics of high-level operations can be exploited in order to increase concurrency. As a consequence, undoing a transaction requires compensation of completed subtransact...
