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.

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.

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.

Efficient numerical simulations with Tensor Networks: Tensor Network Python (TeNPy) [PDF]

open access: yesSciPost Physics Lecture Notes, 2018
Tensor product state (TPS) based methods are powerful tools to efficiently simulate quantum many-body systems in and out of equilibrium. In particular, the one-dimensional matrix-product (MPS) formalism is by now an established tool in condensed matter ...

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.

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.
