A scattering layer is introduced at a horizontal water–bottom interface to account for effects of attenuation due to bottom volume scattering. Using a wide‐angle parabolic equation, a formula for the local mean intensity level is found for a shal

Trauma is a major cause of maternal death in pregnancy. The pregnant woman who has been involved in an episode leading to her arrival in an accident and emergency department presents with specific problems that often require specialist attention. The

Sensitivities of relative intensity, interference wavelength, and horizontal wave number predictions to input parameters in two-layer isospeed models of shallow-water, low-frequency (less than 100 Hz) acoustic propagation problems are examined. The i

Accuracy of relative intensity and horizontal wave‐number predictions from parabolic approximation models of shallow water, low‐frequency (less than 100 Hz) acoustic propagation problems is examined. Effects of input parameter uncertainties and b

The global and local stability of a one‐way, nth‐order, time‐domain paraxial equation (TDPEn) to an acoustic wave equation [M. D. Collins, J. Acoust. Soc. Am. 86, 1097–1102 (1989)] is resolved. An operator splitting technique is used to deter

One‐way narrow‐ and wide‐angle three‐dimensional time‐domain paraxial approximations to the wave equation are developed to model acoustic propagation. The approximate equations are designed to be appropriate for ocean applications including

Underwater acoustic signals are powerful scientific tools for probing large regions of the ocean which would otherwise be inaccessible. Oceanographers and other scientists use acoustic energy as a mechanism to examine the structure of ocean regions f

A new parabolic equation (PE) is presented that is independent of k0 and capable of handling relatively large range variations in the index of refraction. This equation is similar to, and ostensibly simpler than, an earlier range refraction PE (RAREP

In this chapter, it is argued that research involving adaptive educational hypermedia will be advanced by attention to two main areas: (a) the articulation of principled design features for adaptive hypermedia systems and (b) rigorous research docume
