Damage Evolution Equation Considering Three Dimensional Growth of Void

Void Avoidance in Three-Dimensional Mobile Underwater Sensor Networks

Mobile underwater sensor networks are usually featured with three-dimensional topology, high node mobility and long propagation delays. For such networks, geographic routing has been shown to be very suitable. However, routing voids pose great challenges on the greedy policy used in most geographic routing protocols. The problem is more severe for underwater sensor networks because of node mobi...

Neumann Problem Three - Dimensional Helmholtz Equation

A method for explicitly solving the exterior Dirichlet problem for the threedimensional Helmholtz equation in terms of the Dirichlet Green's function for Laplace's equation has recently been found [6]. The present work shows how a similar technique may be used to solve the exterior Neumann problem in terms of the corresponding Neumann-Green function for Laplace's equation. The existence of the ...

Three-Dimensional Evolution of the Galactic Fountain

Gas that escapes from the Galactic disk, rises into the halo, cools and falls back, constitutes a “Galactic fountain”. Three-dimensional simulations show that such a fountain model reproduces many of the features that have been observed in the Galaxy and other galaxies such as M31 and M33. Here, these results are reported.

Evolution of three-dimensional unsteady wave modulations

A numerical investigation of nonlinear interaction mechanisms producing large wave energy concentrations, which lead to episodic transient waves, is performed using both a Higher Order Spectral (HOS) model and a three-dimensional (3D) fully nonlinear Numerical Wave Tank (NWT). Self-focusing of wave energy is achieved through modulating a periodic wave train along two orthogonal directions. Nonl...
