Ray tracing in a turbulent, shallow‐water channel

Christian Bjerrum‐Niese, René Lützen, Leif Bjo/rno/
1998 Journal of the Acoustical Society of America  
For closed, axisymmetric geometries, the boundary-value problem can be expressed as a one-dimensional integral equation. Bound-ary shapes can be represented exactly in this formalism.  ...  However, because the leaky modes are not bounded in the lower half-space, the overlap integrals involved in computing the coupling coefficients are undefined.  ...  of 1 m above.  ...

Objective evaluation of vowel pronunciation

Mark J. Bakkum, Reinier Plomp, Louis C. W. Pols
1991 Journal of the Acoustical Society of America  
A simple mode-inversion technique is used to determine bottom-reflection coefficients for the sediments in the pond.  ...  These data provide a means for determining mechanisms for the concentration of methane gas and the formation of gas hydrate.  ...  Plans for the next meetings of ISO/TC43 (in Australia in December 1991 ), and for IEC/TC 29 (in New Zealand, from 25-29 November 1991 } will be discussed.  ...
