Stabilized Finite Element Formulations for Flow Problems
… on developing novel stabilized finite element formulations for flow problems suitable for monolithic approaches to fluid-structure interaction. In addition to the challenges produced by the poor performance of the classical Galerkin method for mixed finite elements, monolithic methods for …

Magnetic resonance image reconstruction from highly undersampled K-Space data using dictionary learning
… we explore the use of an additive multiscale dictionary formulation. This formulation enforces sparsity of the reconstructed image simultaneously at multiple scales (patch sizes) and combines the results at those scales to obtain superior reconstructions. The multiscale dictionary …

A variational multiscale a-posteriori error estimation method for nearly incompressible elasticity
… elasticity that is based on variational multiscale concepts. The displacement field is decomposed into coarse scales captured by the finite element mesh and fine scales representing the part of the physics unresolved by the mesh. This solution field decomposition addresses the artificial …
