Geometric convergence rates for cardinal spline subdivision with general integer arity

open access: yesJournal of Numerical Analysis and Approximation Theory, 2019
A rigorous convergence analysis is presented for arbitrary order cardinal spline subdivision with general integer arity, for which the binary case, with arity two, is a well-studied subject.

Efficient spline regression for neural spiking data.

open access: yesPLoS ONE, 2021
Point process generalized linear models (GLMs) provide a powerful tool for characterizing the coding properties of neural populations. Spline basis functions are often used in point process GLMs, when the relationship between the spiking and driving ...

Cardinal interpolation by multivariate splines [PDF]

open access: yesMathematics of Computation, 1987
The purpose of this paper is to investigate cardinal interpolation using locally supported piecewise polynomials. In particular, the notion of a commutator is introduced and its connection with the Marsden identity is observed. The order of a commutator is shown to be equivalent to the Strang and Fix conditions that arise in the study of the local ...

Sampling from a system-theoretic viewpoint: Part II - Noncausal solutions [PDF]

open access: yes, 2010
This paper puts to use concepts and tools introduced in Part I to address a wide spectrum of noncausal sampling and reconstruction problems. Particularly, we follow the system-theoretic paradigm by using systems as signal generators to account for ...

Nasal and temporal curvatures of lamina CRIBROSA in myopic eyes

open access: yesScientific Reports, 2022
Little is known about the myopic characteristics of lamina cribrosa (LC) curvature. As such, we investigated nasal and temporal LC curvatures in myopia.

An advanced variant of an interpolatory graphical display algorithm [PDF]

open access: yes, 2004
In this paper an advanced interpolatory graphical display algorithm based on cardinal B-spline functions is provided. It is well-known that B-spline functions are a flexible tool to design various scale rapresentations of a signal.
