Numerical simulation of capillary gravity waves excited by an obstacle in shallow water; pp. 278–284 [PDF]
Proceedings of the Estonian Academy of Sciences, 2015 Capillary gravity waves excited by an obstacle are investigated by numerical simulations. Under the resonant condition for which large-amplitude solitary waves are generated, solutions of the Euler equations show that the capillary effects induce the ...

On the generation of solitary waves observed by Cluster in the near-Earth magnetosheath [PDF]
Nonlinear Processes in Geophysics, 2005 Through case studies involving Cluster waveform observations, solitary waves in the form of bipolar and tripolar pulses have recently been found to be quite abundant in the near-Earth dayside magnetosheath.

Numerical Study on Collisions of Solitons of Surface Waves in Finite Water Depth
Fluids, 2023 Head-on collisions between two solitary waves in the framework of the nonlinear Schrödinger (NLS) equation were investigated using the Fourier spectral method. When solitary waves undergo collision, the peak value of surface elevation (hereafter referred

Brief communication: Multiscaled solitary waves [PDF]
Nonlinear Processes in Geophysics, 2017 It is analytically shown how competing nonlinearities yield multiscaled structures for internal solitary waves in stratified shallow fluids. These solitary waves only exist for large amplitudes beyond the limit of applicability of the Korteweg–de ...

Solitary-wave propagation and interactions for a sixth-order generalized Boussinesq equation
International Journal of Mathematics and Mathematical Sciences, 2005 We study the solitary waves and their interaction for a six-order generalized Boussinesq equation (SGBE) both numerically and analytically. A shooting method with appropriate initial conditions, based on the phase plane analysis around the equilibrium ...

The solitary wave of asexual evolution [PDF]
Proceedings of the National Academy of Sciences, 2003 Using a previously undescribed approach, we develop an analytic model that predicts whether an asexual population accumulates advantageous or deleterious mutations over time and the rate at which either process occurs. The model considers a large number of linked identical loci, or nucleotide sites; assumes that the selection coefficient per site is ...

Large amplitude solitary waves in and near the Earth’s magnetosphere, magnetopause and bow shock: Polar and Cluster observations [PDF]
Nonlinear Processes in Geophysics, 2003 Solitary waves with large electric fields (up to 100's of mV/m) have been observed throughout the magnetosphere and in the bow shock. We discuss observations by Polar at high altitudes ( ~ 4-8 RE ), during crossings of the plasma sheet boundary and ...
