Ranajay Ghosh: The Extreme Mechanics of Fish Scale Inspired Structures Abstract: Dermal scales appeared early in the evolutionary history of vertebrates, most notably in fishes. Their remarkable multi-functional roles include protection from predatory attacks, enhancement of locomotion, camouflaging and thermal regulation. This has led to a tremendous variation in scale type, material, shape, size and organization among species (e.g. fishes, snakes) as well as within […] Categories: Past Seminars |

Real-Time Sea-State Estimation From Measurement Of A Ship’s Motion in Waves Abstract: In standard seakeeping simulations of a ship in irregular seas, the rigid body motions of the ship are computed using a set of semi-analytic integro-differential equations, which model the response of the ship including non-linear and history dependent forces. Using this type of model allows one to model the response of the ship in […] Categories: Past Seminars |
