TLDR
In this paper, a discussion of the behavior of the solution as the mesh width tends to zero is presented, and the applicability of the method to more general difference equations and to those with arbitrarily many independent variables is made clear.Abstract:
Problems involving the classical linear partial differential equations of mathematical physics can be reduced to algebraic ones of a very much simpler structure by replacing the differentials by difference quotients on some (say rectilinear) mesh. This paper will undertake an elementary discussion of these algebraic problems, in particular of the behavior of the solution as the mesh width tends to zero. For present purposes we limit ourselves mainly to simple but typical cases, and treat them in such a way that the applicability of the method to more general difference equations and to those with arbitrarily many independent variables is made clear.read more

Predictive-corrective incompressible SPH
TL;DR: This work presents a novel, incompressible fluid simulation method based on the Lagrangian Smoothed Particle Hydrodynamics model that clearly outperforms the commonly used weakly compressible SPH (WCSPH) model by more than an order of magnitude while the computations are in good agreement with the WCSPH results.

Shape recovery algorithms using level sets in 2-D/3-D medical imagery: a state-of-the-art review
TL;DR: This paper is an attempt to explore these geometric methods, their implementations and integration of regularizers to improve the robustness of these topologically independent propagating curves/surfaces in medical image segmentation.

Forward-and-backward diffusion processes for adaptive image enhancement and denoising
TL;DR: The proposed structure tensor is neither positive definite nor negative, and switches between these states according to image features, resulting in a forward-and-backward diffusion flow where different regions of the image are either forward or backward diffused according to the local geometry within a neighborhood.
