AVERAGING OF DIFFERENCE SCHEMES

Mathematics of the USSR-Sbornik, 1987
The author considers the family of difference operators \(A_{\epsilon}u=\epsilon^{-2}(\sum_{y}p^{\epsilon}(x,y)u(y)-u(x))\) on the uniform grid of the mesh \(\epsilon\) ; x,y\(\in Q\), a bounded domain in \(R^ n\). Here \(p^{\epsilon}(x,y)=p^{\epsilon}(y,x)\geq 0\) (x\(\neq y)\); \(| p^{\epsilon}(x,x)| c,\epsilon\); \(\sum_{i}p^{\epsilon}(x,x+\epsilon ...

Reminiscences about Difference Schemes

Journal of Computational Physics, 1999
The article is the keynote address given by the author at the symposium ``Gudunov's method for gas dynamics: Current applications and future developments'' held at Michigan University in May 1997 in honour of S. K. Godunov. It is concerned with which is nowadays called ``Godunov's scheme'' and its later modifications.

Difference schemes or element schemes?

International Journal for Numerical Methods in Engineering, 1979
AbstractSeveral examples are presented to illustrate how standard finite differnce schemes for the wave eqation (e.g. Lax–Wendroff, Leafrog, etc.) can be developed from finite element analysis. The development of the diffrence schemes from the element schemes is made possible by using Galerkin's method on both the spacial and temporal dimensions.

$\epsilon$-convergent splines difference scheme

Publicationes Mathematicae Debrecen, 1994
A singular boundary value problem \(- \varepsilon u'' + p(x)u = f(x)\), \(x \in [0,1]\), \(u(0) = u_ 0\), \(u(1) = u_ 1\) is solved where \(0 < \varepsilon \ll 1\), \(p,f \in C^ 2 [0,1]\), \(p(x) \geq \beta > 0\) and \(p'(0) = p'(1) = 0\). A method is given for which the truncation error \(R\) is bounded by \(\| R \| < Mh \sqrt \varepsilon\) in the ...

Different schemes for different teams

Computer Fraud & Security, 2009
There has been a lot of talk recently about ‘parceling’ or ‘parcel mule scams’ whose victims are ‘mules’ who pass on goods acquired with dirty money. Parceling is a variant of ‘money mule scams’, differing from them in terms of dynamics and type of ‘hook’ (job offers, dating services, or even fake charitable organisations that ask the victim to help ...
