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 ...

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.

Numerical solution of fractional Sturm-Liouville equation in integral form [PDF]

open access: yes, 2014
In this paper a fractional differential equation of the Euler-Lagrange / Sturm-Liouville type is considered. The fractional equation with derivatives of order $\alpha \in \left( 0,1 \right]$ in the finite time interval is transformed to the integral form.

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 ...

Towards a Spectral Method of Moments using Computer Aided Design [PDF]

open access: yesAdvances in Radio Science, 2019
We present first numerical examples of how the framework of isogeometric boundary element methods, in the context of electromagnetism also known as method of moments, can be used to achieve higher accuracies by elevation of the degree of basis functions.
