The Shortest Path Problem and Its Critical Edge in Uncertain Environment

open access: yesIEEE Access, 2019
In order to make strategic, tactical and operational decisions for the shortest path in an uncertain environment. Firstly, the information transmission time expectation-variance shortest path model in uncertain environment is proposed. Secondly, to avoid

Simulation of Supersymmetric Models with a Local Nicolai Map [PDF]

open access: yes, 1998
We study the numerical simulation of supersymmetric models having a local Nicolai map. The mapping can be regarded as a stochastic equation and its numerical integration provides an algorithm for the simulation of the original model.

Some non monotone schemes for Hamilton-Jacobi-Bellman equations [PDF]

open access: yes, 2018
We extend the theory of Barles Jakobsen to develop numerical schemes for Hamilton Jacobi Bellman equations. We show that the monotonicity of the schemes can be relaxed still leading to the convergence to the viscosity solution of the equation.

Multilevel ensemble Kalman filtering for spatio-temporal processes

open access: yes, 2020
We design and analyse the performance of a multilevel ensemble Kalman filter method (MLEnKF) for filtering settings where the underlying state-space model is an infinite-dimensional spatio-temporal process.

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 ...

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 Complete Framework for Acousto-Electric Tomography With Numerical Examples

open access: yesIEEE Access, 2020
Acousto-electric tomography (AET) involves three steps to retrieve the distribution of conductivity in a domain of interest (DOI): measure the potential on the DOI boundary (usually with a limited number of electrodes set there), compute the power ...
