#ModConFlex researcher Vicente Ocqueteau co-authored a study of small oscillations of a floating cylinder:
"On an Initial Value Problem Describing the Small Oscillations of a Floating Cylinder" (V.Ocqueteau and M.Tucsnak) establishes #existence, #uniqueness and #regularity results for the #solutions of the governing #equations.

We study a coupled PDE-ODE system modeling the small oscillations of a floating cylinder interacting with small water waves. We consider the case when the floating is supposed to be an infinite circular cylinder, so that the equations of the free surface of the fluid can be written in one space dimension. The governing equations are formulated as an abstract evolution equation in a suitable Hilbert space, and we establish the well-posedness of the associated initial value problem. A key element of the proof is the analysis of a partial Dirichlet-to-Neumann map on an unbounded domain with a non-smooth boundary.
Last few days (deadline: January 18) for this call for an 18-month paid research internship (“assegno professionalizzante”) at #INGV #OsservatorioEtneo in #Catania to work on the modelling of plastic transport by water waves:
Feel free to share it within and outside of the Fediverse, especially if you know people who are looking and may be interested.

Rogue wave (Oceanography 🌊)
Rogue waves are unusually large, unpredictable, and suddenly appearing surface waves that can be extremely dangerous to ships and isolated structures such as lighthouses. They are distinct from tsunamis, which are often almost unnoticeable in deep waters and are caused by the displacement of water due to other phenomena. A rogue wave at the s...

Can a computer learn from the past and anticipate what will happen next, like a human? You might not be surprised to hear that some cutting-edge AI models could achieve this feat, but what about a computer that looks a little different—more like a tank of water?
