this study deals with the 3d recovering of magnetic susceptibility model by incorporating the sparsity-based constraints in the inversion algorithm. for this purpose, the area under prospect was divided into a large number of rectangular prisms in a mesh with unknown susceptibilities. tikhonov cost functions with two sparsity functions were used to recover the smooth parts as well as the sharp ...

Sparse stealth attack constructions that minimize the mutual information between state variables and observations are proposed. The construction is formulated as design of a multivariate Gaussian distribution aims to while limiting Kullback-Leibler divergence under without attack. sparsity constraint incorporated support distribution. Two heuristic greedy algorithms for first algorithm assumes ...
