In this paper, we propose an extended Levenberg-Marquardt (ELM) framework that generalizes the classic Levenberg-Marquardt (LM) method to solve the unconstrained minimization problem min where ρ(r(x)) ...

A coupled boundary element (BEM) - finite element (FEM) approach is presented to accurately model structure-acoustic interaction systems. The coupled BEM/FEM analysis is compared with existing ...
