Ships Maneuvering Simulations in a Seaway: How close are we to reality?

This paper provides overview of the currently available theoretical methods and their capabilities in relation to simulations of the maneuvering behavior of displacement type of ships in a seaway. It has been considered that the ships are engaged in typical type of maneuvers such are for example Zig-Zag and Turning maneuvers according to IMO...

Numerical solution of nonlinear acoustic wave problems employing a green's function approach

The design of phased array transducers for medical diagnostic ultrasound asks for an understanding of the nonlinear propagation of acoustic wavefields. Most existing numerical models are based on the linearized model equations, but in the recent decades several numerical models have been developed that incorporate weak nonlinear propagation as...
