A numerical method to solve a nonlocal dispersive wave system.
(2011-10-13)
We use a spectral method to solve numerically a generalization of an integro-differential system
proposed by Choi and Camassa [4] as a model to describe internal waves propagating at the
interface of two immiscible ...
Spin-wave-theory analytic solution of a Heisenberg model with long-range interactions on a Bethe lattice
(1997)
An analytic solution for the Heisenberg Hamiltonian with arbitrarily long-range, ferromagnetic and/or antiferromagnetic, interactions on a Bethe lattice is obtained in the semiclassical approximation (S→∞). The density of ...
Summation of partial wave expansions in the scattering by long range potentials. I
(1977-01-01)
Punctual Padé approximants are considered as a summation method of the slowly convergent partial wave expansions associated with the scattering by long range potentials. The asymptotic behavior of the family of sequences ...

Meteorite impacts in the ocean: the danger of tsunamis on the coast of Buenos Aires Province, Argentina
(Springer, 2020-07)
Comets, meteorites, or asteroids impacting against the Earth are not unusual events. Such impacts on the ocean could produce tsunamis which can reach coastal areas. This paper aimed to analyze the tsunami wave heights on ...
Modulational instability analysis of surface-waves in the Bénard-Marangoni phenomenon
(1995-10-15)
By using the long-wave approximation, a system of coupled evolutions equations for the bulk velocity and the surface perturbations of a Bénard-Marangoni system is obtained. It includes nonlinearity, dispersion and dissipation, ...

Longshore wave energy flux: Variability and trends in the southern coast of Buenos Aires, Argentina
(Elsevier Science, 2017-11)
Variability and trends of the longshore wave energy flux were analyzed between Bahía Blanca and Mar del Plata, along the southern coast of Buenos Aires, Argentina. Longshore energy flux was assessed from wave parameters ...
Hydroelastic stationary problem on tsunami waves generation
(2004)
A two-layered system is considered: a compressible fluid layer of constant depth overlies an homogeneous elastic half-space containing a source of disturbances, which are assumed to be longitudinal steady waves. The vertical ...
