Abstract Using the framework of random walks in random scenery, Cohen and Samorodnitsky (2006) introduced a family of symmetric α-stable motions called local time fractional stable motions. When α = 2, these processes are precisely fractional Brownian motions with 1/2 < H < 1. Motivated by random walks in alternating scenery, we find a complementary family of symmetric α-stable motions which we...

The operability of a vessel in the sea environment, i.e. the capability to accomplish its mission is a major performance indicator of the vessel. It is well known that adverse sea conditions induce significant dynamic motions, velocities, accelerations and loads, which deteriorate the performance of both the crew and the various subsystems onboard, including the hull form itself. For example, t...

The prediction of ship motions and quiescent periods, is paramount importance for the maritime industry. capability to predict these events sufficiently in advance has potential improve safety efficiency several marine operations, such as landing take-off on aircraft carriers, transfer cargo, mating operations between ships. Several models have been proposed literature period. This work will re...
