Parametric curves with Pythagorean binormal
Advances in Computational Mathematics, 2014 The authors present a new class of rational spatial curves with rational binormal. They call this new class PB curves. Also, the construction of this kind of curves (PB curves) is presented based upon the dual curve representation and the Euler-Rodrigues frame obtained from quaternion polynomials.

Radical parametrizations of algebraic curves by adjoint curves
Journal of Symbolic Computation, 2011 We present algorithms for parametrizing by radicals an irreducible curve, not necessarily plane, when the genus is less o equal to 4 and they are defined over an algebraically closed field of characteristic zero. In addition, we also present an algorithm for parametrizing by radicals any irreducible plane curve of degree $d$ having at least a point of ...

Catchments do not strictly follow Budyko curves over multiple decades, but deviations are minor and predictable [PDF]
Hydrology and Earth System SciencesQuantification of precipitation partitioning into evaporation and runoff is crucial for predicting future water availability. Within the widely used Budyko framework, which relates the long-term aridity index to the long-term evaporative index ...

Biharmonic Curves in a Strict Walker 3-Manifold
International Journal of Mathematics and Mathematical Sciences, 2022 In this paper, we study the geometry of biharmonic curves in a strict Walker 3-manifold and we obtain explicit parametric equations for biharmonic curves and time-like biharmonic curves, respectively.

Parametric Based Controller for Rapid Prototyping Applications [PDF]
, 1998 A methodology aiming at reproducing in Rapid Prototyping applications, exact parametric curves from CAD data is presented. The approach consists of converting the space-based parametric curves from the CAD system into time-base, such that the equations

Constructing parametric quadratic curves
Journal of Computational and Applied Mathematics, 1999 Constructing a parametric spline curve to pass through a set of data points requires assigning a knot to each data point. In this paper the authors discuss the construction of parametric quadratic splines and present a new method to assign knots to a set of planar data points.

Journal of Numerical Analysis and Approximation TheoryIn this paper, we consider the global optimization problem of non-smooth functions over an \(n\)-dimensional box, satisfying the H\"{o}lder condition. We focus our study on the case when the H\"{o}lder constant is not a priori known.
