A machine learning method is developed which capable of making predictions nonlinear ship motions in a range wave conditions when trained on response data from only single seaway. The formulated around the equations motion time domain, but are augmented with data-driven terms that act to correct force-balance equations. forcing modeled using Long Short-Term Memory (LSTM) recurrent neural networ...

Studies of the effects of the Central American Seaway’s closure on microfossil taxa and stable isotopes of foraminifera previously addressed the timing of emplacement of the Caribbean–tropical eastern Pacific sill, changes in marine nutrients, evolutionary and paleobiogeographic events associated with closure, and rates of uplift in Central America. However, there have been no quantitative stud...

The Upper Cretaceous was a period when reefs and reef mounds were abundant in many parts of the world (JAMES, 1983). One of the most remarkable features of the Cretaceous carbonate platforms in tropical and subtropical environments of the Tethyan realm, was the development of facies complexes dominated by rudists, with or without associated corals (MASSE & PHILIP, 1981; ROSS & SKELTON, 1993; GI...

In this paper, the large amplitude nonlinear rolling motion and capsizing behavior of an offshore supply vessel hull-form is analyzed. In order to investigate the importance of damping, a dynamical perturbation technique (Vishnubhotla, Falzarano and Vakakis, 1998) is applied to the hull using various approximations to the roll damping. The offshore supply vessel (OSV) is probably one of the mos...

S MAA SEAWAY FALL MEETING SUNY PLATTSBURGH, 2010 Friday night speaker Andrew Granville, University of Montreal The anatomy of integers and permutations Different mathematical subjects have different basic objects -for example, integers for numbers, permutations in combinatorics and group theory. At first sight these objects come from such different worlds that they seem to have very little in c...
