C1 convexity-preserving piecewise variable degree rational interpolation spline
An explicit expression of a C1 piecewise variable degree rational interpolation spline is developed, which produces a convex (concave) interpolant to given convex (concave) data directly.

Shape Preserving Interpolation Using C2 Rational Cubic Spline
This paper discusses the construction of new C2 rational cubic spline interpolant with cubic numerator and quadratic denominator. The idea has been extended to shape preserving interpolation for positive data using the constructed rational cubic spline ...

An Improvement on the Upper Bounds of the Partial Derivatives of NURBS Surfaces
The Non-Uniform Rational B-spline (NURBS) surface not only has the characteristics of the rational Bézier surface, but also has changeable knot vectors and weights, which can express the quadric surface accurately.

Time-domain parametric sensitivity analysis of multiconductor transmission lines [PDF]
We present a new parametric macromodeling technique for lossy and dispersive multiconductor transmission lines (MTLs). This technique can handle design parameters, such as substrate or geometrical layout features, and provide time-domain sensitivity ...

Towards a More General Type of Univariate Constrained Interpolation With Fractal Splines
Recently, in [Electronic Transaction on Numerical Analysis, 41 (2014), pp. 420-442] authors introduced a new class of rational cubic fractal interpolation functions with linear denominators via fractal perturbation of traditional nonrecursive rational ...
