A generalized regularization scheme for solving singularly perturbed parabolic PDEs
Many problems in science and engineering can be modeled as singularly perturbed partial differential equations. Solutions to such problems are not generally continuous with respect to the perturbation parameter(s) and hence developing stable and ...

Elliptic reconstruction and a posteriori error estimates for fully discrete linear parabolic problems [PDF]
We derive a posteriori error estimates for fully discrete approximations to solutions of linear parabolic equations. The space discretization uses finite element spaces that are allowed to change in time. Our main tool is an appropriate adaptation of the

We establish the well-posedness of boundary value problems for a family of nonlinear higherorder parabolic equations which comprises some models of epitaxial growth and thin film theory. In order to achieve this result, we provide a unified framework for

A Strongly A-Stable Time Integration Method for Solving the Nonlinear Reaction-Diffusion Equation
The semidiscrete ordinary differential equation (ODE) system resulting from compact higher-order finite difference spatial discretization of a nonlinear parabolic partial differential equation, for instance, the reaction-diffusion equation, is highly ...

STUDY OF AMMONIA VOLATILIZATION IN SOME NORTHERN IRAQ SOILS [PDF]
Ammonia volatilization phenomena from urea fertilizer was studied by using three different textures of calcareous soil(loamy sand ,clay loamand clay) from Mosul city – northern Iraq, classified as calciorthids .Urea was added at three rates (100,200 and ...

Method of lines transpose: High order L-stable O(N) schemes for parabolic equations using successive convolution [PDF]
We present a new solver for nonlinear parabolic problems that is L-stable and achieves high order accuracy in space and time. The solver is built by first constructing a single-dimensional heat equation solver that uses fast O(N) convolution.
