In these sections we outline some basic ideas underlying the solution of statistical problems in conductivity, acoustics and elasticity. The problems we consider are both static and dynamic and the statistical nature of the problems sterns from the f

Delay of gratification in 3 chimpanzees (Pan troglodytes) was examined by using a paradigm based on research with children. The chimpanzees either pressed a door-bell button during a trial and received one reward (the immediate reward) or did not pre

The objectives of this AASERT grant effort were (1) to incorporate an absorptive bottom into the study of mode energy transfer and decay induced by volume scattering in a shallow channel and (2) to incorporate a piecewise linear sound speed profile i

Methods of solution were considered for solving the generalized coherence function when there is a general bottom impedance condition. In this case the equation contains a diffusion term. Three types of solution were considered: (1) a multi-scale sol

The calculations for considering linear sound-speed profiles in channels have been generalized to treat piece-wise linear sound-speed profiles. Calculation of the scattering coefficients for the linear profile was begun. The case of a channel with a

When a transverse plane wave propagates through a shallow‐water channel with random sound‐speed fluctuations, the waveforms at different transverse separations no longer correlate perfectly. The associated coherence falls as the in‐line propaga

In order to properly determine the volume scattering in a channel, it is necessary to know the characteristic vertical and horizontal correlation lengths associated with the random index‐of‐refraction fluctuations. The results we have obtained fo

Random dynamic excitation of plates in contact with fluids generally extends over a finite region of the plate. Consequently both excitation and response fields are spatially inhomogeneous. Two‐point correlations of such fields are here described a

Using a three‐scale expansion, we solved the equation governing the propagation of the coherence function in a random medium with a mean index of refraction profile. An expression for the intensity distribution near a caustic was obtained including
