Anti-aliasing with stratified B-spline filters of arbitrary degree [PDF]

open access: yes, 2006
A simple and elegant method is presented to perform anti-aliasing in raytraced images. The method uses stratified sampling to reduce the occurrence of artefacts in an image and features a B-spline filter to compute the final luminous intensity at each ...

A quasi-experimental coastal region eddy diffusivity applied in the APUGRID model [PDF]

open access: yesAnnales Geophysicae, 2020
In this study, Taylor statistical diffusion theory and sonic anemometer measurements collected at 11 levels on a 140 m high tower located in a coastal region in southeastern Brazil have been employed to obtain quasi-empirical convective eddy ...

Implicit Reconstruction of Vasculatures Using Bivariate Piecewise Algebraic Splines [PDF]

open access: yesIEEE Transactions on Medical Imaging, 2012
Vasculature geometry reconstruction from volumetric medical data is a crucial task in the development of computer guided minimally invasive vascular surgery systems. In this paper, a technique for reconstructing the geometry of vasculatures using bivariate implicit splines is developed.

Geometric realizations and duality for Dahmen-Micchelli modules and De Concini-Procesi-Vergne modules

open access: yes, 2015
We give an algebraic description of several modules and algebras related to the vector partition function, and we prove that they can be realized as the equivariant K-theory of some manifolds that have a nice combinatorial description.

Modeling of solitary waves via higher-order predictor-corrector scheme

open access: yesJournal of Taibah University for Science
The combination of the sextic b-spline collocation method and the predictor-corrector method is employed to discretize the Regularized Long Wave Equation (RLWE) fully into two systems of linear algebraic equations.

A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...
