Rossby wave propagation tracks in southern hemisphere mean basic flows associated to generalized frosts over southern South America
(CENTRO CIENCIAS ATMOSFERA UNAM, 2010)
Based on previous observational studies on cold extreme events over southern South America, some recent studies suggest a possible relationship between Rossby wave propagation remotely triggered and the occurrence of frost. ...
Wave friction factor rediscovered
(Springer, 2012)
The wave friction factor is commonly expressed
as a function of the horizontal water particle semi-excursion
(Awb) at the top of the boundary layer. Awb, in turn, is
normally derived from linear wave theory by UwbTw
2p ...
Entrainment threshold of sand- to granule-sized sediments under waves
(Elsevier, 2015)
An improved method is presented to determine the threshold boundary velocity required to entrain sediments under waves, using the non-dimensional group settling velocity of sediments ranging from very fine sand to granules ...
Robust tori in a double-waved Hamiltonian model

Optimal control of infinite dimensional bilinear systems: application to the heat and wave equations
(Springer Verlag, 2018)
In this paper we consider second order optimality conditions for a bilinear optimal control problem governed by a strongly continuous semigroup operator, the control entering linearly in the cost function. We derive first ...
Ocean Buoy for Energy Production: Short Comments on Its Irregular Behavior
(2022-01-01)
Purpose: We investigated the non-linear dynamic behavior of a system for energy production using ocean wave motion. The compound consists of a linear electromagnetic system coupled to a float to move under the action of ...
Orbital stability of standing waves for a system of nonlinear schrödinger equations with three wave interaction
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE MATEMÁTICAUFMG, 2018-01)
Nós estudamos a existência e estabilidade de soluções de ondas estacionárias de um sistema Schrödinger não linear três acoplado relacionado à amplificação Raman em um plasma. Por meio do método da concentração-compactação, ...
Optimal Boussinesq model for shallow-water waves interacting with a microstructure
(2007-10-12)
In this paper, we consider the propagation of water waves in a long-wave asymptotic regime, when the bottom topography is periodic on a short length scale. We perform a multiscale asymptotic analysis of the full potential ...
Effect of nonlinear circularly polarized waves on linear instabilities triggered by an alpha particle beam
(Blackwell Publishing Ltd, 2006)
It is shown that nonlinear left-hand polarized waves can either stabilize or destabilize linear right-hand polarized instabilities triggered by an alpha particle beam in a magnetized electron proton plasma. For differential ...
