Journal of Approximation Theory, 1996 The authors define certain combinations of multiquadrics, denoted as \(\Psi\)-splines, and investigate their properties. In particular, the strong analogy between these \(\Psi\)-splines and the usual polynomial B-splines is pointed out at several places.

Numerical approximation for inverse problem of the Ostrovsky–Burgers equation [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2022 This article considers a nonlinear inverse problem of the Ostrovsky–Burgers equation by using noisy data. Two B-Splines with different levels, the quintic B-spline and septic B-spline, are used to study this problem. For both B-splines, the stability and

Binary basic splines in MRA [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021 $B$-splines were introduced by Carry and Schoenberg. Constructed on a uniform mesh and defined in terms of convolutions, such splines generate a Riesz MRA.

Adaptive Nonparametric Density Estimation with B-Spline Bases
Mathematics, 2023 Learning density estimation is important in probabilistic modeling and reasoning with uncertainty. Since B-spline basis functions are piecewise polynomials with local support, density estimation with B-splines shows its advantages when intensive ...

Finite Element Analysis based on A Parametric Model by Approximating Point Clouds
Remote Sensing, 2020 Simplified models are widely applied in finite element computations regarding mechanical and structural problems. However, the simplified model sometimes causes many deviations in the finite element analysis (FEA) of structures, especially in the non ...

Spline-Based Dense Medial Descriptors for Lossy Image Compression
Journal of Imaging, 2021 Medial descriptors are of significant interest for image simplification, representation, manipulation, and compression. On the other hand, B-splines are well-known tools for specifying smooth curves in computer graphics and geometric design.

Random regression analyses using B-splines to model growth of Australian Angus cattle
Genetics Selection Evolution, 2005 Regression on the basis function of B-splines has been advocated as an alternative to orthogonal polynomials in random regression analyses. Basic theory of splines in mixed model analyses is reviewed, and estimates from analyses of weights of Australian ...
