Multiple-knot and rational cubic beta-splines
, 1989 Goodman (Properties of Beta-splines. J. Approx. Theory 44 , 2 (June 1985), 132-153) gave an explicit formula for cubic Beta-splines on a uniform knot sequence with varying β1 and β2 values at the knots.

About a family of C2 splines with one free generating function [PDF]
Computer Science Journal of Moldova, 2005 The problem of interpolation of discrete set of data on the interval [a, b] representing the function f is investigated. A family of C*C splines with one free generating function is introduced in order to solve this problem.

A cubic spline technique for the one dimensional heat conduction equation
, 1971 A new method is developed for the numerical solution of the heat conduction equation in one space dimension by replacing the space derivative with a cubic spline approximation and the time derivative with a finite- difference approximation. The method is

Systemic Lipid Peroxidation and Colorectal Cancer Risk: A Time‐Varying Relationship
International Journal of Cancer, EarlyView.Experimental studies in animals suggest that oxidative stress (OxS) declines as cancer progresses. Whether this occurs in humans, however, remains unclear. The authors of the present study addressed this question by analyzing lipid, DNA, and RNA oxidation biomarkers in relation to colorectal cancer (CRC) risk in patients from Shanghai and the United ...

A rational cubic spline with tension
, 1989 A rational cubic spline curve is described which has tension control parameters for manipulating the shape of the curve. The spline is presented in both interpolatory and rational B-spline forms, and the behaviour of the resulting representations is ...
