A novel time-domain Green?s function is developed for dealing with two-dimensional interaction between water waves and floating bodies with considering viscous dissipation effects based on the ?fairly perfect fluid? model. In the Green?s function, the te...

A carbonaceous material obtained from wood wastes (SW-Mn) was initially used for the removal of pharmaceuticals in water by a carbocatalytic system. The SW-Mn material adsorbed only 41% of the diclofenac (DCF) and 3% of the valsartan (VAL). Interestingly...

In this paper, we study the variations of holograms of a moving source in an inhomogeneous ocean waveguide. It is assumed that intense internal waves (internal solitons) are the reason for the inhomogeneities of the shallow water waveguide. The results o...

Flapping foils for augmenting thrust production have drawn attention as a means of assisting ship propulsion in waves due to their high efficiency rate compared to traditional screw propellers. However, they can also offer substantial resistance reductio...

This paper secures solitary waves and conservation laws to the familiar Korteweg?de Vries equation and Gardner?s equation with three dispersion sources. The traveling wave hypothesis leads to the emergence of such waves. The three sources of dispersion a...
