Modeling the Links Between the Chemical, Electrical and Contractile Calcium Dynamics in a Heart Cell

, 2016
Calcium dysregulation is a signi cant cause of fatal cardiac arrythmias, but it is an incompletely understood phenomenon and diffcult to predict. Cardiac calcium levels can be modelled as a system of partial differential equations linking the electrical,

Efficient Computation for a Reaction-Diffusion System with a Fast Reaction in Two Spatial Dimensions Using COMSOL Multiphysics

, 2009
We study a reaction-diffusion system of three chemical species, where two chemicals react with a much faster rate than the other reaction in the model. We are interested in the asymptotic limit as the rate becomes in finite.

Performance Studies of the Blossom V Algorithm

, 2015
The Blossom V algorithm is used in graph theory to compute a perfect matching of minimum cost. We conducted performance studies on the algorithm using the maya cluster in the UMBC High Performance Computing Facility to better understand the performance ...

FEM Convergence Studies for 2-D and 3-D Elliptic PDEs with Smooth and Non-Smooth Source Terms in COMSOL 5.1

, 2015
Numerical theory provides the basis for quanti cation on the accuracy and reliability of a FEM solution by error estimates on the FEM error vs. the mesh spacing of the FEM mesh. This paper presents techniques needed in COMSOL 5.1 to perform computational
