Journal of Ocean Engineering and Science, 2022 In this work, the Benjamin-Bona-Mahony-Burgers (BBMB) equation is solved using an improvised cubic B-spline collocation technique. This equation describes the propagation of small amplitude waves in a nonlinear dispersive medium, in the modeling of ...

Journal of Computational and Applied Mathematics, 1994 The main subject of this paper is the convolution of spline functions. In particular, the author gives an expression for the convolution of a spline over nonuniform knots with \(B\)-splines as a linear combination of \(B\)-splines of higher order. The coefficients are expressed in terms of divided differences and can be evaluated by a stable recurrence

Isogeometric Resolution of the Brinkman-Forchheimer-Darcy [PDF]
Journal of Applied and Computational MechanicsIn this paper, we employ the finite element method based on non-uniform rational B-splines function approximation to solve the nonlinear Brinkman-Forcheimer-Darcy equation in a simply connected and bounded Lipschitz domain Ω.

A quadratic trigonometric B-Spline as an alternate to cubic B-spline
Alexandria Engineering Journal, 2022 The idea of the quadratic trigonometric spline (QTS) for the curve modeling approach inspired this paper using a quadratic trigonometric function presented in it. By creating B-spline-like local support basis functions, a competent freeform curve design approach is created.

B‐splines image approximation using resampled chordal parameterization
IET Image ProcessingImage processing often requires filtering, which can be effectively performed by using B‐spline surface approximation. This article presents a fast method of approximating data in rectangular (image) form using such surfaces. The method considers dynamic

LOCALLY REFINED SPLINES REPRESENTATION FOR GEOSPATIAL BIG DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 When viewed from distance, large parts of the topography of landmasses and the bathymetry of the sea and ocean floor can be regarded as a smooth background with local features.

A Reverse Non-Stationary Generalized B-Splines Subdivision Scheme
Mathematics, 2021 In this paper, two new families of non-stationary subdivision schemes are introduced. The schemes are constructed from uniform generalized B-splines with multiple knots of orders 3 and 4, respectively. Then, we construct a third-order reverse subdivision
