Propagation of elastic waves through textured polycrystals: application to ice
(Royal Society Publishing, 2015)
The propagation of elastic waves in polycrystals is
revisited, with an emphasis on configurations relevant
to the study of ice. Randomly oriented hexagonal
single crystals are considered with specific, nonuniform,
probability ...
Streaming patterns in Faraday waves
(Cambridge University, 2017)
Waves patterns in the Faraday instability have been studied for decades. Besides therich dynamics that can be observed on the waves at the interface, Faraday waves hidebeneath them an elusive range of flow patterns —or ...
Sediment entrainment under fully developed waves as a function of water depth, boundary layer thickness, bottom slope and roughness
(ELSEVIER, 2010)
Many sediment entrainment equations for oscillatory waves are based on the linear (Airy) theory for deep
water, but at the depth where such waves begin to transport sediments they commonly have trochoidal or
cnoidal ...
Stability of an inverse problem for the discrete wave equation and convergence results
(Elsevier, 2015)
Using uniform global Carleman estimates for semi-discrete elliptic and hyperbolic equations, we study Lipschitz and logarithmic stability for the inverse problem of recovering a potential in a semi-discrete wave equation, ...
Nonlinear neumann boundary stabilization of the wave equation using rotated multipliers
(2010-04)
We study the boundary stabilization of the wave equation
by means of a linear or nonlinear Neumann feedback. The rotated
multiplier method leads to new geometrical cases concerning the active
part of the boundary where ...

(Elsevier, 2015)
Using uniform global Carleman estimates for semi-discrete elliptic and hyperbolic equations, we study Lipschitz and logarithmic stability for the inverse problem of recovering a potential in a semi-discrete wave equation, ...
A note on the stability and instability of travelling wave of Korteweg-de Vries type : the periodic case.
(2012-10-04)
In this paper we adapt the work of M. Grillakis, J. Shatah, and W. Strauss, or J. Bona, P.
Souganidis and W. Strauss to the periodic case in spaces having the mean zero property in order
to establish the orbital ...
Digital image correlation applied to the calculation of the out-of-plane deformation induced by the formation of roll waves in a non-Newtonian fluid
(Spie-Soc Photo-Optical Instrumentation Engineers, 2016)
A method based on digital image correlation (DIC) is implemented for measuring the height of the roll waves developed in a non-Newtonian fluid flowing on an inclined channel. A projector and a high-resolution digital camera, ...
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 ...
New parametric decays of proton beam-plasma electromagnetic waves
(Blackwell Publishing Ltd, 2002)
Ion beam-plasma interactions are the source of wave activity in several space environments. Therefore the study of these waves and their parametric decays are very important in space physics. Thus we study parametric decays ...
