Three-Dimensional Array Interpolation Imaging Algorithm of Water Holdup by the Capacitance Array Tool of Oil–Water Two-Phase Flow in Horizontal Wells [PDF]
SensorsDue to the gravitational differentiation effect, the oil–water two-phase flow in the horizontal well exhibits significant asymmetry and inhomogeneity in terms of phase distribution and velocity field.

On integro quartic spline interpolation
Journal of Computational and Applied Mathematics, 2012 Let \([a,b] \subset \mathbb R\) be a compact interval and let \(x_j = a + jh\) \((j=0,\dots, n)\) with \(h =(b-a)/n\) be equidistant knots. The authors consider the following problem of integro spline interpolation: For given integral values \(I_j\) of a function \(y: [a,b] \to \mathbb R\) on \([x_j,x_{j+1}]\) \((j=0,\dots,n-1)\) and given values \(y_k

Stretch-Energy-Minimizing B-Spline Interpolation Curves and Their Applications
Mathematics, 2023 In this paper, we propose a new method to construct energy-minimizing cubic B-spline interpolation curves by minimizing the approximated stretch energy. The construction of a B-spline interpolation curve with a minimal approximated stretch energy can be ...

Convergence of Integro Quartic and Sextic B-Spline interpolation [PDF]
Sahand Communications in Mathematical Analysis, 2018 In this paper, quadratic and sextic B-splines are used to construct an approximating function based on the integral values instead of the function values at the knots.

Linear/linear rational spline interpolation
Mathematical Modelling and Analysis, 2010 For a strictly monotone function y on [a, b] we describe the construction of an interpolating linear/linear rational spline S of smoothness class C 1. We show that for the linear/linear rational splines we obtain ¦S(xi ) − y(xi )¦8 = O(h 4) on uniform ...

Interpolation by Complex Splines [PDF]
Transactions of the American Mathematical Society, 1978 In this paper we solve the problem of interpolation by certain class of cardinal complex splines. This solution is used to complete the study of cardinal trigonometric splines started in [ 10 ] and also to give shorter proofs and to complete the results found for the interpolation problem by ...

The EH Interpolation Spline and Its Approximation
Abstract and Applied Analysis, 2014 A new interpolation spline with two parameters, called EH interpolation spline, is presented in this paper, which is the extension of the standard cubic Hermite interpolation spline, and inherits the same properties of the standard cubic Hermite ...
