Chebyshev Functional Link Spline Neural Filter for Nonlinear Dynamic System Identification

IEEE Transactions on Circuits and Systems - II - Express Briefs, 2022
In order to increase the nonlinear fitting performance of functional link neural network (FLNN), a novel chebyshev functional link spline neural filter (CFLSNF) to apply in system identification is proposed.

Pseudospectral method for solving the fractional one-dimensional Dirac operator using Chebyshev cardinal functions

Physica Scripta, 2023
In this paper, a numerical method is introduced to find the eigenvalues and eigenfunctions of the Caputo fractional Dirac operator. To this end, the problem reduces to a Volterra integral equation with a weakly singular kernel.

Chebyshev Systems of Minimal Degree

SIAM Journal on Mathematical Analysis, 1984
Let \(\{f_ i\}^ n\!_ 0\) be a set of continuous real valued functions on [a,b]. In the paper it is proved that the functions \(f_ if_ j\), \(i,j=0,...,n\) form a Chebyshev system of minimal degree \(2n+1\) iff the functions \(f_ i\) are of the form \(f_ i(x)=\omega(x)(u(x))^ i, i=0,...,n\) where \(\omega\) (x)\(\neq 0\), \(x\in [a,b]\) and u(x) is a ...

Chebyshev Expansion Applied to Dissipative Quantum Systems

The Journal of Physical Chemistry A, 2016
To determine the dynamics of a molecular aggregate under the influence of a strongly time-dependent perturbation within a dissipative environment is still, in general, a challenge. The time-dependent perturbation might be, for example, due to external fields or explicitly treated fluctuations within the environment. Methods to calculate the dynamics in

Vandermonde systems on Gauss–Lobatto Chebyshev nodes

Applied Mathematics and Computation, 2005
Methods for factorization of the inverses of the Vandermonde matrices on Gauss-Lobatto Chebyshev nodes are presented and an algorithm for solving the primal and the dual system is given. Asymptotic estimates of the Frobenius norm of both the Vandermonde matrix and its inverse and an explicit formula for its determinant are derived. Results of numerical
