Variety interaction between k-lump and k-kink solutions for the generalized Burgers equation with variable coefficients by bilinear analysis

open access: yesResults in Physics, 2021
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]

open access: yes, 2003
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.

Simultaneous Imaging of Primaries and Multiples Based on Wavelet Estimation and Stereographic Imaging Condition

open access: yesIEEE Access, 2020
Multiple reflections contain abundant structural information about the subsurface because of their smaller reflection angles and wider coverage. Multiple imaging has increasingly attracted attention.

A solitary-wave solution to a perturbed KdV equation [PDF]

open access: yes, 2000
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

open access: yesResults in Physics, 2023
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

open access: yesResults in Engineering, 2022
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]

open access: yesApplied Numerical Mathematics, 2022
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
