This study has the objective of assessing the feasibility of using LiDAR (Light Detection and Ranging) and laser communications techniques for localization of moving undersea targets using coordinated multiple UUV operations. This coordination includ

Finite element techniques for the simulation of electromagnetic wave propagation are, like all conventional element based approaches for wave problems, limited by the ability of the polynomial basis to capture the sinusoidal nature of the solution. T

We present a finite element model for acoustic scattering from an elastic object situated near (or intersecting) the surface separating two fluid domains, each of semi-infinite extent. The fluid domains are truncated using a perfectly matched layer (

We demonstrate the advantages of using p-version finite element approximations for structural-acoustics problems in the mid-to-high frequency regime. We then present a sub-domain-based a posteriori error estimation procedure to quantify the errors in

We present new infinite element formulations for solving acoustic scattering and radiation problems in the exterior of long, slender bodies. The new infinite elements are geometrically constructed from a prolate spheroid inscribed by the scatterer. T

A high-order finite element infrastructure is described for the numerical solution of the vibratory response of fluid–structure systems in the mid-frequency range. Underlying variational forms along with the use of an unstructured, topology-based,

We compare the accuracy of a variety of approximate boundary conditions (ABCs) and two versions of an infinite element method (IEM) for approximating solutions of exterior Helmholtz problems. The infinite elements are of variable order in the radial

A rapidly convergent boundary‐element method that has a high‐accuracy capability is developed for the solution of the exterior Neumann problem for the Helmholtz equation. The approach makes use of the boundary‐operator combination idea of Burto
