Univariate approximating schemes and their non-tensor product generalization

Open Mathematics, 2018
This article deals with univariate binary approximating subdivision schemes and their generalization to non-tensor product bivariate subdivision schemes. The two algorithms are presented with one tension and two integer parameters which generate families

Implicit Curvilinear Interpolation [PDF]

, 2008
The shifting operator is applied to generate implicit interpolating equations for curves defined by three and four equidistant data. The equations trade the abscissa of the interpolated point for another curvilinear measurement.

Applications of operational calculus: Trigonometric interpolating equation for the nine-point prism and robust center point formulas

, 2020
A general method for obtaining a trigonometric-type interpolating equation for the eight-point cubical array is illustrated. It can often be used to reproduce a ninth datum at an arbitrary point near the center of the array by adjusting a variable ...

On The Computation Of Periodic Spline Wavelets

, 1995
For many applications in signal processing and numerical analysis, it is important to use periodic scaling functions and wavelets. The aim of this paper is a constructive approach to periodic spline wavelets and to related decomposition and ...

Chaotic dynamics in the generalized Cheeger problem: Numerical analysis of Lyapunov exponents with varying distributions

Results in Control and Optimization
This study examines chaotic behavior in the generalized Cheeger problem, also known as the constrained isoperimetric problem, by deriving a dynamical system based on the evolution of the generalized Cheeger constant under time-varying mass and shear ...
