Water wave interactions with perforated elastic disks: Quadratic pressure discharge condition

Wave Propagation in Generalized Thermodiffusion Elastic Medium with Impedence Boundary Condition

In the present investigation, we study the reflection of plane waves, that is, Longitudinal displacement wave(P-Wave), Thermal wave(T-Wave) and Mass Diffusive wave(MD-Wave) in thermodiffusion elastic-half medium which is subjected to impedence boundary condition in context of one relaxatioon time theory given by Lord and Shulman theory (L-S) and the Coupled theory (C-T) of thermoelasticity. The...

Wave Energy Dissipation Using Perforated and Non Perforated Piles

The indispensable vital structure in any harbor is a breakwater in order to make available calm water region inshore. Pile breakwater can be employed as a small coastal protection structure where tranquility required is low. This study is concerned with CFD study on the performance of perforated hollow pile to dissipate wave energy and the novelty of this investigation is the role of perforatio...

Experimental Studies of Wave Transmission through Single Perforated Sheets and Upright Perforated Wave Filters

Solitary water wave interactions

Our concern in this talk is the problem of free surface water waves, the form of solitary wave solutions, and their behavior under collisions. Solitary waves for the Euler equations have been described since the time of Stokes. In a long wave perturbation regime they are well described by single soliton solutions of the Korteweg deVries equation (KdV). It is a famous result that multiple solito...

Quadratic Siegel Disks with Rough Boundaries.

In the quadratic family (the set of polynomials of degree 2), Pe-tersen and Zakeri [PZ] proved the existence of Siegel disks whose boundaries are Jordan curves, but not quasicircles. In their examples, the critical point is contained in the curve. In the first part, as an illustration of the flexibility of the tools developped in [BC], we prove the existence of examples that do not contain the ...
