Climate-driven endemic cholera is modulated by human mobility in a megacity

Andrea Rinaldo, Francisco Javier Perez Saez

Although a differential sensitivity of cholera dynamics to climate variability has been reported in the spatially heterogeneous megacity of Dhaka, Bangladesh, the specific patterns of spread of the resulting risk within the city remain unclear. We build on ...

Fluid-structure interaction during hydraulic transients in pressurized pipes: experimental and numerical analyses

David Ferràs Segura

Pressurized pipes may be endangered by failure due to excessive hydraulic transients, the so-called waterhammer. These pressure waves are strongly affected by fluid-structure interaction (FSI), unsteady skin friction, dry friction or pipe-wall viscoelastic ...
