Finally some physics! Ok, so it took 27.5 years to convert this to pdf, but worth the wait I hope: shallow_water_v16. The problem is the propagation of sound waves in shallow water and I will just quote from the note I added near the front of this first electronic version of the original hardcopy document:
“Green’s functions, emergence of geometrical acoustics from partial differential equations, Euler polynomials, asymptotic series, absorption handling in reflection coefficients together lead to analytical solutions and fast algorithms. This is a complete work: It includes all derivations and all programs and does not overly reference external material.”
Feedback welcome. Either here or at my email firstname.lastname@example.org.
