A gymkhana to discover and generate curves in a cooperative work
Multidisciplinary Journal for Education, Social and Technological Sciences, 2014 The student who access the University understands a curve as a function represented by an equality involving the Cartesian variables x and y. But he does not know another great set of curves such as those described by parametric equations and polar ...

Equiareal Parameterization of Triangular Bézier Surfaces
Mathematics, 2022 Parameterization is the key property of a parametric surface and significantly affects many kinds of applications. To improve the quality of parameterization, equiareal parameterization minimizes the equiareal energy, which is presented as a measure to ...

Nonparametric IV estimation of shape-invariant Engel curves [PDF]
, 2003 This paper concerns the identification and estimation of a shape-invariant Engel curve system with endogenous total expenditure. The shape-invariant specification involves a common shift parameter for each demographic group in a pooled system of Engel

Parametric Regression on the Grassmannian [PDF]
, 2015 We address the problem of fitting parametric curves on the Grassmann manifold for the purpose of intrinsic parametric regression. As customary in the literature, we start from the energy minimization formulation of linear least-squares in Euclidean ...

Parametric Manifolds I: Extrinsic Approach [PDF]
, 1994 A parametric manifold can be viewed as the manifold of orbits of a (regular) foliation of a manifold by means of a family of curves. If the foliation is hypersurface orthogonal, the parametric manifold is equivalent to the 1-parameter family of ...

Effects of the core radius of an isothermal ellipsoidal gravitational lens on the caustics and the critical curves [PDF]
, 2004 We study the effect of the core radius of an isothermal ellipsoidal gravitational lens on the caustics and the critical curves. We derive an analytic expression of the caustics for an isothermal ellipsoidal gravitational lens via a sixth-order algebraic ...
