A time-domain formulation for sound propagation in rigid-frame porous media, including waveform attenuation and dispersion, is developed. The new formulation is based on inversion of the relaxation functions from a previous model [Wilson DK, Ostashev

Finite-difference, time-domain (FDTD) calculations are typically performed with partial differential equations that are first order in time. Equation sets appropriate for FDTD calculations in a moving inhomogeneous medium (with an emphasis on the atm

New fusion methods for an operationally adaptive (OA) system for prediction of acoustic transmission loss (TL) in the atmosphere are developed in this paper. The OA system uses expert neural network predictors, each corresponding to a specific range

Simulating the stable atmospheric boundary layer (SABL) presents a significant challenge to numerical models due to the interactions of several processes with widely-varying scales. The goal of this Challenge Project is to more clearly define the rol

Formulation and implementation of time-domain boundary conditions (TDBCs) at the surface of a reactive porous material are made challenging by the slow decay, complexity, or noncausal nature of many commonly used models of porous materials. In this p
