B-Splines with Arbitrary Connection Matrices
, 2008 We consider a space of Chebyshev splines whose left and right derivatives satisfy linear constraints that are given by arbitrary non-singular connection matrices.

Shape Preserving Properties and Convergence of Univariate Multiquadric Quasi-Interpolation
, 1994 : With a suitable modification at the endpoints of the range, quasi--interpolation with univariate multiquadrics OE(x) = p c 2 + x 2 is shown to preserve convexity and monotonicity. If h is the maximum distance of centres, convergence of the quasi--

Energy wavelet analysis of time series
, 2002 In this paperwe will approach the analysis of time series by the discrete Haar wavelet trasnform and by the energy distribution. it is shown that the wavelet coefficients are strictly related to the scheme of finite differences, thus giving information ...

Generalized Taylor Series and Peano Kernel Theorem
<p>As in the polynomial case, non-polynomial divided differences can be viewed as a discrete analog of derivatives. This link between non-polynomial divided differences and derivatives is defined by a generalization of the derivative operator.

The Uniform Convergence of Thin Plate Spline Interpolation in Two Dimensions
, 1994 that is not a subset of a single straight line, then we prove that a sequence of thin plate spline interpolants converges to f uniformly on D. Specifically, we require h!0, where h is now the least upper bound on the numbers fd(x; V) : x 2 Dg and where

Approximation of Contact Geometry in the Dynamical Simulation of Wheel-Rail Systems
, 1996 Models for the geometrical contact of wheel and rail are a basic component of multibody system (MBS) models for wheel-rail systems. Approximations are used to get sufficiently differentiable contact conditions that can be evaluated efficiently.

Linear Independence and Stability of Piecewise Linear Prewavelets on Arbitrary Triangulations
, 1999 : In this paper we establish linear independence and stability of certain piecewise linear prewavelets over arbitrary bounded triangulations. These prewavelets are natural generalizations of the locally supported element constructed by Kotyczka and ...

The Apolar Bilinear Form in Geometric Modeling
, 1998 Some recent methods of Computer Aided Geometric Design are related to the apolar bilinear form, an inner product on the space of homogeneous multivariate polynomials of a fixed degree, already known in 19th century invariant theory.

An Adaptive Two-Level Method For The Coupling Of Nonlinear FEM-BEM Equations
, 1999 . In this paper an a posteriori error estimate for nonlinear coupled FEM-BEM equations is derived by using hierarchical basis techniques. Based on the properties of two-level additive Schwarz operators for (linearized) differential equations and weakly ...
