Parametric PDEs: Sparse or Low-Rank Approximations?
, 2016 We consider adaptive approximations of the parameter-to-solution map for elliptic operator equations depending on a large or infinite number of parameters, comparing approximation strategies of different degrees of nonlinearity: sparse polynomial ...

Modeling static microstructure of shape memory alloy via Legendre wavelets collocation method
Journal of Physics: Conference Series, 2019 Abstract The static microstructures of square-to-rectangular phase transformations are modeled in the current paper. Governing equations are described by the static Navier equations. The analysis of the simulation has been finished via Legendre wavelets collocation method.
