This newest edition adds new material to all chapters, especially in mathematical
propagation models and special applications and inverse techniques. It has updated …

An ocean-ice-acoustic coupled model is configured for the Beaufort Sea. The model uses
outputs from a data assimilating global scale ice-ocean-atmosphere forecast to drive a …

A three-dimensional (3D) finite difference (FD) model with formal fourth-order accuracy has
been developed for the ocean acoustic Helmholtz equation (HE), which can be used to …

This chapter presents some common sound propagation modeling methods: ray tracing,
wave number integration, normal-mode expansion, parabolic equation approximation, and …

Parabolic equation (PE) method is an efficient tool for modelling underwater sound
propagation, particularly for problems involving range dependence. Since the PE method …

A numerical approach for the treatment of irregular ocean bottoms within the framework of
the standard parabolic equation is proposed. The present technique is based on the …

This thesis deals with the propagation of infrasonic waves above irregular boundaries using
a numerical approach based on the parabolic equation (PE) method. The first part of the …

A computer program for simulation of electromyographic (EMG) signal, which represents the
electric activity of a muscle during contraction, has been built. Some of the simulation …

Let the D value in a reasonable position can make the application of progressive scoring
equation more rationally. In this research, D is set on the basis of 0.5 s spacing, and then the …
