Abstract: In this paper we aim to proof the possibility to reconstruct a bicomplex sparse signal, with high probability, from a reduced number of bicomplex random samples. Due to the idempotent representation of the bicomplex algebra… read more here.

Abstract: We propose a new method for including sparsity constraints into potential field data inversion using a Laplacian kernel. The method obtains three-dimensional density distributions, which are at best a proxy for geological structures. Compressive sensing… read more here.
