Discrete Cubic Interpolatory Splines

Publications of the Research Institute for Mathematical Sciences, 1992
In the present paper, existence, uniqueness and convergence properties of a discrete cubic spline which satisfies certain averaging interpolatory condition are established. This type of interpolatory condition has been studies earlier for usual cubic splines in [3].

Stereo matching based on segmented B‐spline surface fitting and accelerated region belief propagation

IET Computer Vision, 2015
The authors propose a new stereo matching algorithm based on an iterative optimisation framework including bi‐cubic B‐spline surface fitting and accelerated region belief propagation (BP).

A Two-Stage Estimation Approach to Cox Regression Under the Five-Parameter Spline Model

Mathematics
The Cox proportional hazards model is one of the most popular regression models for censored survival data. In the Cox model, the baseline hazard function is often modeled by cubic spline functions.

Impact of modified B-splines on particle-in-cell modeling for electron-ion nonlinear dynamics

Cogent Engineering
The present study explores the impact of implementing a third-order B-spline as a kernel function with random modifications in Particle-In-Cell (PIC) simulations for nonlinear electron-ion dynamics.

Cubic spline functions revisited

Journal of Computational and Applied Mathematics
In this paper a fourth order asymptotically optimal error bound for a new cubic interpolating spline function, denoted by Q-spline, is derived for the case that only function values at given points are used but not any derivative information. The bound seems to be stronger than earlier error bounds for cubic spline interpolation in such setting such as

A novel stochastic ten non-polynomial cubic splines method for heat equations with noise term

Partial Differential Equations in Applied Mathematics
In this paper, a new numerical method for solving a class of stochastic partial differential equations is presented. The proposed method is based on a non-polynomial cubic spline algorithm with an O(h4) local truncation error.
