Ellipse-based principal component analysis for self-intersecting curve reconstruction from noisy point sets
(SPRINGER, 2011-03-01)
Surface reconstruction from cross cuts usually requires curve reconstruction from planar noisy point samples. The output curves must form a possibly disconnected 1-manifold for the surface reconstruction to proceed. This ...
Sensitivity analysis in optimized parametric curve fitting
(EMERALD GROUP PUBLISHING LIMITED, 2015-03-02)
Purpose-Curve fitting from unordered noisy point samples is needed for surface reconstruction in many applications. In the literature, several approaches have been proposed to solve this problem. However, previous works ...
Divsion Algorithm and Construction of Curves with Many Points
(Universidad Nacional de Colombia, 2013-12)
We give a simple and effective method for the construction of
algebraic curves over finite fields with many rational points. The curves are
given as Kummer covers of the projective line.
Consistency of Extended Nelson-Siegel Curve Families with the Ho-Lee and Hull and White Short Rate Models
(Scientific Research Publishing, 2017-11)
Nelson and Siegel curves are widely used to fit the observed term structure of interest rates in a particular date. By the other hand, several interest rate models have been developed such their initial forward rate curve ...
IntCal, SHCal, or a mixed curve? choosing a 14C Calibration curve for archaeological and paleoenvironmental records from Tropical South America
(University of Arizona. Department of Geosciences, 2018-06)
Because the 14C calibration curves IntCal and SHCal are based on data from temperate latitudes, it remains unclear which curve is more suitable for archaeological and paleoenvironmental records from tropical South America. ...
Approximations by mini mixed finite element for the Stokes-Darcy coupled problem on curved domains
(Isci-inst Scientific Computing & Information, 2021-03)
In this work we solve a Stokes-Darcy coupled problem in a plane curved domain using curved elements. We approximate the velocity-pressure pair by applying the MINI-element method, for the whole coupled problem. We show ...
Minimal matrices and the corresponding minimal curves on flag manifolds in low dimension
(Elsevier Science Inc, 2009-04)
In general C*-algebras, elements with minimal norm in some equivalence class are introduced and characterized. We study the set of minimal hermitian matrices, in the case where the C*-algebra consists of 3 × 3 complex ...
Natural vibrations of anisotropic plates with an internal curve with hinges
(Pergamon-Elsevier Science Ltd, 2017-01)
The objective of this paper is to propose a general algorithm to obtain approximate analytical solutions for the study of the free vibrations of a rectangular anisotropic thin plate with an internal curved line hinge and ...
