L0 Regularization parameter for sparse DOA estimation of coherent signals with modeling errors

Sparse methods have been recently introduced in Direction-Of-Arrival (DOA) estimation as an alternative to subspace-based methods and Maximum Likelihood (ML) techniques. This paper proposes a low complexity sparse L0-regularized method for DOA…

Co-optimization of a high temperature thermal storage as per its modeling accuracy

Coupling energy networks becomes unavoidable in order to decarbonize human usages, increase global energy efficiency and ensure flexibility in so-called “multi-energy” network. In such a network, high temperature thermal energy storage (HTTES) can…
