Combined approximation algorithms for interactive design of road routes in CAD
Российский технологический журнал, 2023 Objectives. The aim of the work is to create algorithms for approximating a sequence of points on a plane by arcs of clothoids and circles. Such a problem typically arises in the design of railroad and highway routes.

Polynomial splines as examples of Chebyshevian splines [PDF]
Numerical Algorithms, 2012 Spaces of geometrically continuous (piecewise defined) functions are considered in this paper. Such functions in use for approximation purposes of all sorts may be piecewise polynomials or more generally coming from extended Chebyshev spaces. The latter are natural generalisations of polynomial spline structures.

New approach for solution of volterra integral equations using spline quasi-interpolant [PDF]
Journal of Hyperstructures, 2019 In this paper, we present quadratic rule for approximate solution of integrals using spline quasi-interpolant. The methodis applied for solving the linear Volterra integral equations. Also the convergence analysis of the method is given.

Verification of the Spline Method and its Application to Curvilinear Objects
Technical Transactions, 2019 Two methods of interpolation are presented in this article: interpolation with the help of orthogonal polynomials and interpolation on a cubic spline path (with the help of glued-together functions).

Comparison Between T-Spline Surface and NURBS Surface [PDF]
Engineering and Technology Journal, 2015 This research uses T-spline for surface modeling and compares it with NURBS modeling to get the best modeling points between the two methods. The comparison will be through surface analysis and manufacturing process.T-Splines surfaces typically have 50 ...

Implicit cubic B-spline scheme for the fractional Black-Scholes model with Caputo-Hadamard derivative [PDF]
Journal of Mahani Mathematical ResearchIn this study, we introduce a novel numerical scheme for solving the Black–Scholes equation endowed with a Caputo-Hadamard fractional time derivative. The temporal derivative is discretized via a finite-difference approach, ensuring both stability and ...
