Convex Obstacles from Travelling Times

We consider situations 10m Coaxial where rays are reflected according to geometrical optics by a set of unknown obstacles.The aim is to recover information about the obstacles from the travelling-time data of the reflected rays using geometrical methods and observations of singularities.Suppose that, for a disjoint union of finitely many strictly c

Experimental Determination of Non-Linear Roll Damping of an FPSO Pure Roll Coupled with Liquid Sloshing in Two-Row Tanks

Wave excited roll motion poses danger for moored offshore vessels such as Floating Production Storage and Offloading (FPSO) because they cannot divert to avoid bad weather.Furthermore, slack cargo tanks are almost always present in FPSOs by design.These pose an increased risk of roll instability due to the presence of free surfaces.The most common
