Cosmological Non-Gaussian Signature Detection: Comparing Performance of Different Statistical Tests

EURASIP Journal on Advances in Signal Processing, 2005
Currently, it appears that the best method for non-Gaussianity detection in the cosmic microwave background (CMB) consists in calculating the kurtosis of the wavelet coefficients.

Multiscale Simulations for Coupled Flow and Transport Using the Generalized Multiscale Finite Element Method

Computation, 2015
In this paper, we develop a mass conservative multiscale method for coupled flow and transport in heterogeneous porous media. We consider a coupled system consisting of a convection-dominated transport equation and a flow equation.

Learning Algorithms for Coarsening Uncertainty Space and Applications to Multiscale Simulations

Mathematics, 2020
In this paper, we investigate and design multiscale simulations for stochastic multiscale PDEs. As for the space, we consider a coarse grid and a known multiscale method, the generalized multiscale finite element method (GMsFEM).
