Forward propagation of acoustic pressure pulses in 3D soft biological tissue [PDF]
A simulation method for forward propagation of acoustic pressure pulses in a medium with three-dimensional (3D) spatially-variable acoustic properties is presented.

In this paper, we study the generalized Burgers equation with variable coefficients which is considered in soliton theory and generated by considering the Hirota bilinear operators. We retrieve some novel exact analytical solutions, including 2-lump-type

A pseudodifferential equation with damping for one-way wave propagation in inhomogeneous acoustic media [PDF]
A one-way wave equation is an evolution equation in one of the space directions that describes (approximately) a wave field. The exact wave field is approximated in a high frequency, microlocal sense.

A solitary-wave solution to a perturbed KdV equation [PDF]
We derive the approximate form and speed of a solitary-wave solution to a perturbed KdV equation. Using a conventional perturbation expansion, one can derive a first-order correction to the solitary-wave speed, but at the next order, algebraically ...

Vector combined cnoidal wave and soliton solutions for a 3D partially nonlocal CNLSE
A 3D distributed-coefficient coupled nonlinear Schrödinger equation(CNLSE) with the partially nonlocal nonlinearity(PNN) for locality in two transverse directions and non-locality in the longitudinal direction becomes the center of attention in this ...

Water waves resonance and its interaction with submerged breakwater
Wave resonance phenomena in a basin can cause enormous damage to the environment. Resonance is caused by external forces coming into the basin with a similar period as the natural period of the basin.

A three-dimensional Laguerre one-way wave equation solver [PDF]
A finite difference algorithm based on the integral Laguerre transform in time for solving a three-dimensional one-way wave equation is proposed. This allows achieving high accuracy of calculation results. In contrast to the Fourier method, the approach does not need to solve systems of linear algebraic equations with indefinite matrices. To filter the
