Conservative numerical methods for model kinetic equations [PDF]

open access: yes, 2007
A new conservative discrete ordinate method for nonlinear model kinetic equations is proposed. The conservation property with respect to the collision integral is achieved by satisfying at the discrete level approximation conditions used in deriving the ...

A numerical evaluation of solvers for the periodic Riccati differential equation [PDF]

open access: yes, 2009
Efficient and accurate structure exploiting numerical methods for solving the periodic Riccati differential equation (PRDE) are addressed. Such methods are essential, for example, to design periodic feedback controllers for periodic control systems ...

From the Kirsch-Kress potential method via the range test to the singular sources method

open access: yes, 2022
We review three reconstruction methods for inverse obstacle scattering problems. We will analyse the relation between the Kirsch-Kress potential method 1986, the range test of Kusiak, Potthast and Sylvester (2003) and the singular sources method of ...

Shifted Jacobi collocation scheme for multidimensional time-fractional order telegraph equation [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2020
We propose a numerical scheme to solve a general class of time-fractional order telegraph equation in multidimensions using collocation points nodes and approximating the solution using double shifted Jacobi polynomials.

A Reliable Combination of Double Laplace Transform and Homotopy Analysis Method for Solving a Singular Nonlocal Problem with Bessel Operator

open access: yesAxioms, 2023
In this article, we present a numerical iterative scheme for solving a non-local singular initial-boundary value problem by combining two well known efficient methods. Namely, the homotopy analysis method and the double Laplace transform method.

A second-order numerical approximation of a singularly perturbed nonlinear Fredholm integro-differential equation [PDF]

open access: yes, 2023
We consider a singularly perturbed problem for a nonlinear first-order Fredholm integrodifferential equation. Our aim is to build and analyze a numerical approach with uniform convergence in the epsilon-parameter.

Distributed Input and State Estimation Using Local Information in Heterogeneous Sensor Networks

open access: yesFrontiers in Robotics and AI, 2017
A new distributed input and state estimation architecture is introduced and analyzed for heterogeneous sensor networks. Specifically, nodes of a given sensor network are allowed to have heterogeneous information roles in the sense that a subset of nodes ...

Numerical simulation of anomalous infiltration in porous media [PDF]

open access: yes, 2015
Nonlinear time-fractional diffusion equations have been used to describe the liquid infiltration for both subdiffusion and superdiffusion in porous media.
