Ball convergence of a stable fourth-order family for solving nonlinear systems under weak conditions
, 2017 We present a local convergence analysis of fourth-order methods in order to approximate a locally unique solution of a nonlinear equation in Banach space setting.

Approximation by Radial Basis Functions with Finitely Many Centers
, 1996 : Interpolation by translates of "radial" basis functions \Phi is optimal in the sense that it minimizes the pointwise error functional among all comparable quasi--interpolants on a certain "native" space of functions F \Phi .

On Multi-Level Bases for Elliptic Boundary Value Problems
, 1995 We study the multi-level method for preconditioning a linear system arising from a Galerkin discretization method of an elliptic boundary value problem of order 2r. The solution is approximated in the spline space S 0 1 (4 n ) when r = 1 and S r\Gamma1

A unified local convergence for Chebyshev-Halley-type methods in Banach space under weak conditions
, 2015 We present a unified local convergence analysis for Chebyshev-Halley- type methods in order to approximate a solution of a nonlinear equation in a Banach space setting. Our methods include the Chebyshev; Halley; super-Halley and other high order methods.

Analysis of Curve Reconstruction by Meshless Parameterization
, 2003 : This paper proposes and analyzes a method called meshless parameterization for reconstructing curves from unordered point samples. The method solves a linear system of equations based on convex combinations so as to map the sampled points into ...

Natural alternatives for one dimensional median filtering
, 2004 For practical purposes median smoothers have often been considered the basic components for the construction of simple non-linear smoothers for removing impulsive noise before any subsequent linear signal extraction from a sequence.
