An ultra-weak three-field finite element formulation for the biharmonic and extended Fisher--Kolmogorov equations
Rekha Khot, Bishnu P. Lamichhane, Ricardo Ruiz-Baier
This paper discusses a so-called ultra-weak three-field formulation of the biharmonic problem where the solution, its gradient, and an additional Lagrange multiplier are the three…
Efficient Data-Driven Leverage Score Sampling Algorithm for the Minimum Volume Covering Ellipsoid Problem in Big Data
Elizabeth Harris, Ali Eshragh, Bishnu Lamichhane +2
The Minimum Volume Covering Ellipsoid (MVCE) problem, characterised by observations in dimensions where , can be computationally very expensive in the big data reg…
A priori and a posteriori error bounds for the fully mixed FEM formulation of poroelasticity with stress-dependent permeability
Arbaz Khan, Bishnu P. Lamichhane, Ricardo Ruiz-Baier +1
We develop a family of mixed finite element methods for a model of nonlinear poroelasticity where, thanks to a rewriting of the constitutive equations, the permeability depends on…
Swell induced vibrations of a thickening ice shelf over a shoaling seabed
Michael Meylan, Muhammad Ilyas, Bishnu Lamichhane +1
A solution method is developed for a model of ice shelf vibrations in response to ocean waves, in which the ice shelf thickness and seabed beneath the ice shelf vary over distance,…
Approximation of noisy data using multivariate splines and finite element methods
Elizabeth Harris, Bishnu Lamichhane, Quoc Thong Le Gia
We compare a recently proposed multivariate spline based on mixed partial derivatives with two other standard splines for the scattered data smoothing problem. The splines are defi…
Energy Resolved Neutron Imaging for Strain Reconstruction using the Finite Element Method
Riya Aggarwal, Mike Meylan, Bishnu Lamichhane +1
A pulsed neutron imaging technique is used to reconstruct the residual strain within a polycrystalline material from Bragg edge strain images. This technique offers the possibility…
