Extended Darboux frame curvatures of Frenet curves lying on parametric 3-surfaces
Kuwait Journal of Science, 2019 In this paper, we consider a Frenet curve lying on a parametric hypersurface in 4-dimensional Euclidean space and obtain the expressions of its curvatures with respect to the ...

REVISITING THE ORDERED FAMILY OF LORENZ CURVES [PDF]
Lorenz curve; Gini index Abstract: Sarabia et al. (1999) present a basic model to create ordered families of Lorenz curves, along with basic theorems that describe the conditions for the models to satisfy the definition of the Lorenz curve.

Low level direct interpolation for parametric curves [PDF]
, 2012 This article presents an algorithm for the direct interpolation of parametric planar curves C(u) with a CNC machine. It expresses parametric planar curves as sequences of machine tool axes discrete movements of BLU size.

Carbon Abatement Leaders and Laggards Non Parametric Analyses of Policy Oriented Kuznets Curves [PDF]
We study the eventual structural differences of climate change leading ‘actors’ such as Northern EU countries, and ‘lagging actors’ - southern EU countries and the ‘Umbrella group’ - with regard to long run (1960-2001) carbon-income relationships ...

TASK Quarterly, 2002 The paper presents a new modeling method of boundary geometry in boundary valueproblems by ν-spline curves. To define a smooth boundary geometry both B´ezier and B-spline curves are applied. At the segment join points B´ezier curves ensure continuity C1,
