Ck spline functions and linear operators

, 1994
We present in this article the structural and algebraic properties of the linear operators generated by Ck spline functions. These operators are commonly encountered in most numerical applications of linear dynamical systems. A program written in Reduce,

Numerical Study of Multi-Term Time-Fractional Sub-Diffusion Equation Using Hybrid L1 Scheme with Quintic Hermite Splines

Mathematical and Computational Applications
Anomalous diffusion of particles has been described by the time-fractional reaction–diffusion equation. A hybrid formulation of numerical technique is proposed to solve the time-fractional-order reaction–diffusion (FRD) equation numerically.

NURBS Approximations of Real Algebraic Curves

, 2007
We use a combination of both algebraic and numerical techniques to construct a C 1 - continuous, piecewise (m; n) rational B-spline ffl-approximation of a real algebraic plane curve of degree d.

Spline on a generalized hyperbolic paraboloid

, 2011
In this paper, we present an approach to produce a kind of spline, which is very close to G2-continuity. For a control polygon, we can construct a polyhedron.

Application of the method of spline-collocations to the solution of dynamic and static problems for structurally inhomogeneous cylindrical shells

Доповiдi Нацiональної академiї наук України, 2019
The method of spline collocation, in contrast to the use of double trigonometric series for the approximation of the displacements of points of the middle surface of a shell, allows us to significantly expand the class of applied problems and, in some ...

Real-Time Trajectory Generation for Constrained Nonlinear Dynamical Systems Using Non-Uniform Rational B-Spline Basis Functions

, 2008
The thesis describes a new method for obtaining minimizers for optimal control problems whose minima serve as control policies for guiding nonlinear dynamical systems to achieve prescribed goals under imposed trajectory and actuator constraints.

Generalized spline spaces over T-meshes: Dimension formula and locally refined generalized B-splines

, 2016
Univariate generalized splines are smooth piecewise functions with sections in certain extended Tchebycheff spaces. They are a natural extension of univariate (algebraic) polynomial splines, and enjoy the same structural properties as their polynomial ...

Algebraic structure of generalized splines

, 2019
G sonlu bir çizge, R birimli değişmeli bir halka ve α, G çizgesinin kenarlarını R halkasının idealleri ile etiketleyen bir kenar etiketleme fonksiyonu olsun. (G,α) ikilisine bir kenar etiketli çizge denir. Bir (G,α) kenar etiketli çizgesi üzerinde bir genelleştirilmiş spline, komşu köşelerin üzerindeki etiketlerin farkı bu köşeleri bağlayan kenar ...
