The Crested Ibis Nipponia nippon was once thought to be extinct in the wild until seven birds were discovered in a remote mountain village in China in 1981. Studies suggested that winter-flooded rice fields play an essential role in nest site selection by the Crested Ibis and hence in their survival. Considerable efforts were therefore made to conserve the winter-flooded rice fields, but these ...

Predictions of the wave-induced response floating structures that are moored in a harbour or coastal waters require an accurate description (nonlinear) evolution waves over variable bottom topography, interactions with structure, and dynamics mooring system. In this paper, we present new advanced numerical model to simulate structure is arbitrary nearshore region. The based on non-hydrostatic a...

6 The scaled boundary finite-element method (SBFEM) is a novel semi-analytical method 7 developed in the elasto-statics and elasto-dynamics areas that has the advantages of com8 bining the finite-element method with the boundary-element method. The SBFEM method 9 weakens the governing differential equation in the circumferential direction and solves the 10 weakened equation analytically in the ...

Coarse-grained beaches are particularly prevalent in the UK, composed of accumulations of either gravel, or mixed sand and gravel sediments. Understanding and predicting their morphological behaviour in response to short-term and long-term forcing has been the subject of recent research. Despite the focus on sandy beaches, it is important to understand that the balance of processes that govern ...

This paper presents a theoretical modeling of power and energy transduction of structurally-bonded piezoelectric wafer active sensors (PWAS) for structural health monitoring (SHM). After a literature review of the state of the art, we developed a model of power and energy transduction between the PWAS and a structure containing multimodal ultrasonic guided waves. The use of exact Lamb waves mod...

We study properties of solitary wave solutions of three evolution equations arising in the modeling of internal waves Our experiments indicate that broad classes of initial data resolve into solitary waves but also suggest that solitary waves do not interact exactly thus suggesting two of these equa tions are not integrable In the course of our numerical simulations interesting meta stable quas...
