An alternative approach is proposed here to investigate the problem of scattering surface water waves by a vertical permeable plate submerged in deep within framework linear wave theory. Using Havelock’s expansion potential, associated boundary value reduced second kind hypersingular integral equation order 2. The unknown function expressed as product suitable weight and an polynomial. 2 evalua...

an analytical study was performed to study effects of thermo-diffusion and chemical reactions on a three-dimensional mhd mixed convective flow of dissipative fluid along an infinite vertical porous plate with transverse sinusoidal suction velocity. the parabolic partial differential equations governing the fluid flow, heat transfer, and mass transfer were solved using perturbation technique and...

The analytical solutions of wave induced horizontal and vertical forces on perforated caissons resting on porous elastic seabed have been established. The solution in the seabed is divided into a symmetric part and an anti-symmetric part. A numerical experiment has been carried out to examine the effects on horizontal forces, vertical forces and phase lags between them due to the relative wave ...

A 1500mm 1200 mm silicon scanning mirror for laser display has been designed and fabricated by deep inductively coupled plasma reactive ion etching (ICPRIE) and flip chip bonding technology. It is a vertically driven electrostatic scanner and composed of two structures having vertical comb fingers. The upper structure is composed of a scanning mirror plate, two torsion bars, a supporting frame ...

a transversely isotropic half-space with axis of material symmetry perpendicular to the free surface supports a flexible circular plate. the contact area of the plate and the half-space is considered to be both frictionless and unbonded (tensionless). the foundation is affected by a vertical static axisymmetric load. detailed analysis of the interaction of these two systems is the target of thi...
