This two-volume work contains the collected papers of F. Ursell, dating from 1946-1992, on ship hydrodynamics, the linear theory of water waves, aerodynamics and acoustics, mathematical methods and oceanography. Ursell's work on ship hydrodynamics is mainly concerned with ships at zero forward speed. It includes the author's pioneering work on the frequency dependence of virtual mass and damping and his contributions to such topics as slender-body theory, decay of the free motion of a floating body, diffractions of head seas, the Kelvin shipwave patterns and the analytic form of the Kelvin...

This is an analysis of multi-dimensional nonlinear dissipative Hamiltonian dynamical systems, subjected to parametic and external stochastic excitations by the Fokker-Planck equation method.
