Numerical Analysis of a Benjamin–Bona–Mahony Type Equation in a Noncylindrical Domain

Mathematical Methods in the Applied Sciences, Volume 49, Issue 2, Page 818-834, 30 January 2026.
ABSTRACT Numerical analysis and simulation for the approximate solution of a Benjamin–Bona–Mahony type equation defined in a noncylindrical domain are presented in this article. The approximate problem is defined using the linearized Crank–Nicolson Galerkin method, which results in a linear algebraic system at each time step while maintaining quadratic

An Inverse Source Technique as a Preliminary Tool to Localize Persons in Indoor Spaces

Mathematical Methods in the Applied Sciences, Volume 49, Issue 1, Page 304-320, 15 January 2026.
ABSTRACT This paper considers an inverse heat source localization problem with applications to indoor person localization from temperature measurements. In particular, this inverse problem consists in the reconstruction of the intensity and position of heat sources from observed temperature data.

Microlayer Model: A Nonlinear Finite Strain Viscoelastoplastic Formulation for Asphalt

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT The microlayer framework is an innovative and powerful approach for the numerical simulation of heterogeneous materials, such as aggregate‐matrix composites across multiple scales. In this study, the microlayer framework is extended for the first time to account for viscoelastic‐elastoplastic material behavior.

Data‐Driven Distributed Safe Control Design for Multi‐Agent Systems

International Journal of Adaptive Control and Signal Processing, Volume 40, Issue 1, Page 137-150, January 2026.
This paper presents a data‐driven control barrier function (CBF) technique for ensuring safe control of multi‐agent systems (MASs) with uncertain linear dynamics. A data‐driven quadratic programming (QP) optimization is first developed for CBF‐based safe control of single‐agent systems using a nonlinear controller. This approach is then extended to the
