A posteriori corrections for cubic and quintic interpolating splines at equally-spaced knots [PDF]
, 1985 The method proposed recently by Lucas [13], for the a posteriori correction of odd degree interpolating periodic splines is extended to non-periodic cubic and quintic ...

Polynomial cubic splines with tension properties [PDF]
, 2010 In this paper we present a new class of spline functions with tension properties. These splines are composed by polynomial cubic pieces and therefore are conformal to the standard, NURBS based CAD/CAM ...

Mathematical Modelling and Analysis, 2017 In this paper we study the problem of the diffusion of one substance through the pores of a porous multi layered material which may absorb and immobilize some of the diffusing substances with the evolution or absorption of heat. As an example we consider

Construction of a family of non-stationary biorthogonal wavelets
Journal of Inequalities and Applications, 2019 The family of exponential pseudo-splines is the non-stationary counterpart of the pseudo-splines and includes the exponential B-spline functions as special members.

Reconstruction Algorithm of Signals from Special Samples in Spline Spaces [PDF]
, 2005 In this paper, we introduce integral sampling and study the reconstruction of signals based on non-uniform average samples in spline subspace. By using a new method, we obtain a new reconstruction formula.

Two-Stage Spline-Approximation with an Unknown Number of Elements in Applied Optimization Problem of a Special Kind [PDF]
Mathematics and Statistics, 2021 Being a continuation of the paper published in Mathematics and Statistics, vol. 7, No. 5, 2019, this article describes the algorithm for the first stage of spline- approximation with an unknown number of elements of the spline and constraints on its parameters. Such problems arise in the computer-aided design of road routes and other linear structures.
