The speed and beam of a ship from its wake's SAR images
TLDR
Estimates of the ship beam and its velocity are dealt with by processing SAR images of the Kelvin and turbulent wakes by employing a novel method that exploits the expansion of the turbulent wake aft a ship. Expand
On Detectability of a Ship's Kelvin Wake in Simulated SAR Images of Rough Sea Surface
TLDR
The influence of ships, wind, and SAR parameters on PMD and PFA is discussed and illustrated that PMD/PFA strongly depend on the sea state. Expand
Floating and fixed artificial habitats: Spatial and temporal patterns of benthic communities in a coral reef environment
TLDR
This study tested the hypothesis that floating and fixed artificial installations in a tropical reef system (Eilat, Red Sea) would support different benthic communities throughout space and time by examining differences in communities recruited onto settlement plates betweenfloating and fixed installations deployed at three different sites along a two-year monitoring period. Expand
Floating and fixed artificial habitats: effects of substratum motion on benthic communities in a coral reef environment
TLDR
Significant differences in the hydrodynamic features associated with habitats of different motion capabilities are found, predominantly in mass-transfer rate, current velocity and shear stress, which are suggested to determine the nature of the benthic communities on floating and fixed habitats.

DEAD-WATER EFFECTS OF A SHIP MOVING IN STRATIFIED SEAS
A linearised theory is presented for the dead-water phenomena. A two-layer fluid model of finite depth is assumed and the solutions for both wave resistance as well as the interface and free-surfaceExpand
Hydroelastic buoyant circular plate in shallow water : a closed form solution
This paper considers a circular buoyant elastic plate of homogeneous stiffness floating in shallow water. The edge of the plate is free of shear forces and bending moments. The plate deflection isExpand
How do larvae attach to a solid in a laminar flow?
TLDR
A hydrodynamic model explaining the mechanism of contact of marine larvae in vertical flows is presented and it is shown that flow vorticity causes a larva to rotate and change the direction of self-thrust, thus leading to its migration across the mean flow. Expand
Moth-inspired navigation algorithm in a turbulent odor plume from a pulsating source
TLDR
This work proposes a navigation strategy that enables a flier to locate an upwind pulsating odor source in a windy environment using a single threshold-based detection sensor, and suggests that in turbulent plumes from a pulsating point source, an instantaneously measurable quantity referred as a “puff crossing time” improves the success rate. Expand
Kelvin and V-like Ship Wakes Affected by Surfactants
Synthetic aperture radar (SAR) ship wake images in light wind and calm sea conditions frequently appear in the form of a bright V with a half-angle of 2 to 3 deg. Sophisticated and conflictingExpand
DEVELOPMENT OF CN MODELS AND THEIR APPLICATION IN SHIP MANOEUVRABILITY STUDIES
To describe ship motion in a horizontal plane, different mathematical models are used. The majority of them are obtained by extension of the hydrodynamic loads in Taylor's series of kinematicExpand
