The weak-form of Helmholtz differential equation, in conjunction with vector test-functions (which are gradients of the fundamental solutions to the Helmholtz differential equation in free space) is… Expand

In order to solve the problem that the existing wireless resource allocation strategies only concern a single wireless base station rather than the entire network, this paper proposed a two-stage wireless networking resource allocation algorithm.Expand

The fine structure of compound eye in Portunus tritubereulatus under different wavelength lights adaptation was studied with electron microscopy. The Portunus tritubereulatus were trained in a… Expand

To predict the sound field in an acoustic problem, the well-known non-uniqueness problem has to be solved. In a departure from the common approaches used in the prior literature, the weak-form of the… Expand

Novel non-hyper-singular (i.e., only strongly-singular) boundary-integral-equations for the gradients of the acoustic velocity potential, involv- ing only O(r −2 ) singularities at the surface of a… Expand
