Towards Rogue Wave Characterization in False Bay, South Africa
Rogue waves are extreme oceanic waves which exceed twice the significant wave height of the wave record. In False Bay, South Africa, a shallow sea mount called rocky bank was suggested by Shipley (1964) to be the cause for increased wave energy along the eastern periphery of False Bay, where it is …

Enhanced Fabrication of Microdroplet Generator Nozzle Arrays: Optimizing KOH Etching for Microfluidic Applications
… A tapering geometry is preferred for acoustic wave focusing and efficient droplet generation, and KOH etching naturally yields pyramids due to preferential removal of the (100) plane versus the (111) plane of single-crystal silicon. Though wet etching is less precise than dry etching, it is …

Analytical and Numerical Studies of the Generation and Propagation of Nonlinear Water Waves by a Wavemaker
… to predict the nonlinear effects of extreme wave events is paramount for the preparation of modern experimental tests in large wave basins. Currently, linear theory is routinely used, hence nonlinear wave-wave interactions between propagating waves are often ignored. In addition, the …

Wave management in 1D and 2D granular systems: designs for stress wave mitigation and control
Controlling stress waves during impact beyond merely dissipating their energy through material fracture, fragmentation, yielding etc., has been a significant focus of research in recent years. Materials exhibiting stress wave control characteristics would enable novel applications, such as for …
