17. Fully Nonlinear Unsteady Three-Dimensional Boundary Element Method for Ship Motions in Waves
Abstract : The prediction of the behavior of ships in a seaway has been an important topic in ship design since the beginning of modern naval architecture. In recent years, computer simulations using numerical methods based on mathematical models of the ship hydrodynamics problem has become a valuable tool for researchers and engineers working in this field.

18. Nonlinear Propagation of Partially Incoherent Light
Abstract : This thesis deals with consequences of partial incoherence on light propagation in nonlinear media. A new approach, based on the Wigner transform method, has beed developed and used to investigate several important problems in nonlinear light propagation. READ MORE

19. Nonlinear pulse propagation and saturation gain grating phenomena in optical fiber devices
Abstract : Nonlinear effects are known to influence the propagation ofoptical waves in fibers already at modest power levels. Thisprovides us with a unique tool to observe nonlinear phenomenaunder comparatively simple experimental conditions and alsoopens the door to numerous important applications. READ MORE

20. Nanomechanical Phenomena in Low-Dimensional Structures
Abstract : This is a compilation thesis which investigates various mechanical phenomena in different low-dimensional nanoscale systems. In the first part, we consider a purely mechanical phenomenon: the sensitivity of the dispersion of a Love-type surface acoustic wave (SAW) to geometry and material parameters. READ MORE
