Sparsity for parametric PDEs with log-gamma random inputs and applications
Dinh Dũng, Van Kien Nguyen, Viet Ha Hoang
We propose a novel method for establishing the sparsity of the coefficients of the Laguerre generalized polynomial chaos expansion of solutions to parametric elliptic PDEs with log…
Bayesian inversion for Electrical Impedance Tomography by sparse interpolation
Quang Huy Pham, Viet Ha Hoang
We study the Electrical Impedance Tomography Bayesian inverse problem for recovering the conductivity given noisy measurements of the voltage on some boundary surface electrodes. T…
Optimal finite elements for ergodic stochastic two-scale elliptic equations
Viet Ha Hoang, Chen Hui Pang, Wee Chin Tan
We develop an essentially optimal finite element approach for solving ergodic stochastic two-scale elliptic equations whose two-scale coefficient may depend also on the slow variab…
Homogenization of a multiscale multi-continuum system
Jun Sur Richard Park, Viet Ha Hoang
We study homogenization of a locally periodic two-scale dual-continuum system where each continuum interacts with the other. Equations for each continuum are written separately wit…
Hierarchical multiscale finite element method for multi-continuum media
Jun Sur Richard Park, Viet Ha Hoang
Simulation in media with multiple continua where each continuum interacts with every other is often challenging due to multiple scales and high contrast. One needs some types of mo…
