Generalized finite difference method applied to solve seismic wave propagation problems. Examples of 3D simulations

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 7706-7726, 15 May 2025.
The simulation of seismic wave propagation generally requires dealing with complex tridimensional geometries that are irregular in shape and have non‐uniform properties, features that make the application of the generalized finite difference method in this field interesting. This work continues the extensive developments by the research team focused on

Generalizing Traub's method to a parametric iterative class for solving multidimensional nonlinear problems

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 7861-7874, 15 May 2025.
In this work, we modify the iterative structure of Traub's method to include a real parameter α$$ \alpha $$. A parametric family of iterative methods is obtained as a generalization of Traub, which is also a member of it. The cubic order of convergence is proved for any value of α$$ \alpha $$.

Flexible development and evaluation of machine‐learning‐supported optimal control and estimation methods via HILO‐MPC

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 35, Issue 7, Page 2835-2859, 10 May 2025.
Abstract Model‐based optimization approaches for monitoring and control, such as model predictive control and optimal state and parameter estimation, have been used successfully for decades in many engineering applications. Models describing the dynamics, constraints, and desired performance criteria are fundamental to model‐based approaches. Thanks to
