Time-reversal acoustics and maximum-entropy imaging

Target location is a common problem in acoustical imaging using either passive or active data inversion. Time-reversal methods in acoustics have the important characteristic that they provide a means of determining the eigenfunctions and eigenvalues of the scattering operator for either of these problems. Each eigenfunction may often be approximately associated with an individual scatterer. The...

A review of finite element methods for time-harmonic acoustics

State-of-the-art finite element methods for time-harmonic acoustics governed by the Helmholtz equation are reviewed. Four major current challenges in the field are specifically addressed: the effective treatment of acoustic scattering in unbounded domains, including local and nonlocal absorbing boundary conditions, infinite elements, and absorbing layers; numerical dispersion errors that arise ...

Empirical Maximum Entropy Methods

A method, which we suggest to call the Empirical Maximum Entropy method, is implicitly present at Maximum Entropy Empirical Likelihood method, as its special, non-parametric case. From this vantage point the entropy-based empirical approach to estimation is surveyed.

Galerkin Generalized Least Squares Finite Element Methods for Time{harmonic Structural Acoustics

Grosh and Pinsky GGLS methods for structural acoustics 1 Abstract Galerkin Generalized Least Squares (GGLS) nite element methods are developed and implemented for modeling the response of uid{loaded structures. A general formalism for the application of this methodology to problems in structural acoustics (the vibration of and elastic structure in contact with an acoustic medium) is presented. ...

Maximum entropy methods for generating simulated rainfall

We desire to generate monthly rainfall totals for a particular location in such a way that the statistics for the simulated data match the statistics for the observed data. We are especially interested in the accumulated rainfall totals over several months. We propose two different ways to construct a joint rainfall probability distribution that matches the observed grade correlation coefficien...
