A numerical solution for the source identification telegraph problem with Neumann condition
In this paper, the source identification problem for the telegraph equation is studied. We propose the first order of accuracy absolute stable difference scheme for the numerical solution of the one-dimensional identification problem for the telegraph ...

dynoGP: Deep Gaussian Processes for Dynamic System Identification
International Journal of Adaptive Control and Signal Processing, EarlyView.This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

IDENTIFICATION OF A SOURCE TERM AND A COEFFICIENT IN A PARABOLIC DEGENERATE PROBLEM
, 2012 The globally in time existence and uniqueness of solutions to inverse problems is one of the most difficult questions to be answered. Even though the direct problems are well-posed in the sense of Hadamard (i.e. existence, uniqueness and stability results hold true), the inverse ones generally are not.

Advanced Engineering Materials, EarlyView.Sustainability assessment requires methodologies that appropriately distinguish between additive and non‐additive material properties. A toxicity‐weighted scoring system is developed and applied that accounts for the disproportionate influence of highly toxic constituents through nonlinear weighting functions, providing more realistic estimates than ...
