Spline functions are polynomials that are cut into pieces with care. Although spline functions date back to work of Euler and Bernoulli, it was Iso Schoenberg who began to study them in earnest. In la...
This paper presents a cubic spline trajectory generation algorithm that produces continuous position, velocity, and acceleration proˉles for 3-axis CNC machines with conˉned axis jerk and tracking err...
This paper, we develop a numerical method for solving a unilateral obstacle problem by using the cubic spline collocation method and the generalized Newton method. This method converges quadratically ...
In the first part of this companion volumes, we present a new flexible alignment model and an iterative algorithm based on an L2-gradient flow. In this second part of the companion volumes, we focus...
In this first part of the companion volumes, we present a new flexible alignment method to align two or more similar images, especially biological images. By minimizing an energy functional measurin...
We use collocation methods to solve fractional boundary value problems. Analytically, we study the existence and uniquenes theorem of the collocation solutions, and discuss some error estimates. We ...
In this paper, we propose a dynamic B-spline technique using general form fourth order geometric PDEs. Basing on discretizaions of Laplace-Beltrami operator and Gaussian curvature over triangular an...
Variational formulations of three fourth order geometric partial di甧rential equations are derived, and based on which mixed 痭ite element methods are presented for constructing G1 smooth B-spline sur...
By a d-dimensional B-spline object (denoted as Od), we mean a B-spline curve (d = 1), a B-spline surface (d = 2) or a B-spline volume (d = 3). By regularization of a B-spline object Od we mean a pro...
Abstract: The usual power function error estimates do not capture the true order of uniform accuracy for thin plate spline interpolation to smooth data functions in one variable. In this paper we prop...
In this study, we use B-spline functions to solve the linear and nonlinear special systems of differential equations associated with the category of obstacle, unilateral, and contact problems. The pro...
In this piece of work, using three spatial grid points, we discuss a new two-level implicit cubic spline method of O(k2 + kh2 + h4) for the solution of quasi-linear parabolic equation , 0< x <1, t > 0...
We consider numerical approximations of the Monge-Ampere equation det D2u = f; f > 0 with Dirichlet boundary conditions on a convex bounded domain in Rn; n = 2; 3. We make a comparative study of thr...
We analyze the space S_{m, m'}^{r, r'} (T) of bivariate functions that are piecewise polynomial of bidegree (m, m') and class C^{r, r'} over a planar T-subdivision. We give a new formula for the dime...
