Aorta zero-stress state modeling with T-spline discretization

open access: yesComputational Mechanics, 2018
The image-based arterial geometries used in patient-specific arterial fluid–structure interaction (FSI) computations, such as aorta FSI computations, do not come from the zero-stress state (ZSS) of the artery.

Applying spline-based phase analysis to macroeconomic dynamics

open access: yesDependence Modeling, 2022
The article uses spline-based phase analysis to study the dynamics of a time series of low-frequency data on the values of a certain economic indicator. The approach includes two stages. At the first stage, the original series is approximated by a smooth

A Generalized Quasi Cubic Trigonometric Bernstein Basis Functions and Its B-Spline Form

open access: yesMathematics, 2021
In this paper, under the framework of Extended Chebyshev space, four new generalized quasi cubic trigonometric Bernstein basis functions with two shape functions α(t) and β(t) are constructed in a generalized quasi cubic trigonometric space span{1,sin2t,(

Multivariate Analysis-Suitable T-Splines of Arbitrary Degree

open access: yesComputational Methods in Applied Mathematics, 2023
Abstract This paper defines analysis-suitable T-splines for arbitrary degree (including even and mixed degrees) and arbitrary dimension. We generalize the concept of anchor elements known from the two-dimensional setting, extend existing concepts of analysis-suitability and show their sufficiency for linearly independent T-splines.

Automatic Generation of T-Splines with Extraordinary Points Based on Domain Decomposition of Quadrilateral Patches

open access: yesMathematics
Isogeometric analysis (IGA) is a numerical methodology for solving differential equations by employing basis functions that preserve the exact geometry of the domain. This approach is based on a class of mathematical functions known as NURBS (Non-Uniform

An Upper Bound of the Bezout Number for Piecewise Algebraic Curves over a Rectangular Partition

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012
A piecewise algebraic curve is a curve defined by the zero set of a bivariate spline function. Given two bivariate spline spaces (Δ) over a domain D with a partition Δ, the Bezout number BN(m,r;n,t;Δ) is defined as the maximum finite number of the ...

A new spline in compression method of order four in space and two in time based on half-step grid points for the solution of the system of 1D quasi-linear hyperbolic partial differential equations

open access: yesAdvances in Difference Equations, 2017
In this paper, we propose a new three-level implicit method based on a half-step spline in compression method of order two in time and order four in space for the solution of one-space dimensional quasi-linear hyperbolic partial differential equation of ...
