Ship’s Trajectory Planning Based on Improved Multiobjective Algorithm for Collision Avoidance

open access: yesJournal of Advanced Transportation, 2019
With vigorous development of the maritime trade, many intelligent algorithms have been proposed to avoid collisions due to resulting casualties and increased costs. According to the international regulations for preventing collisions at sea (COLREGs) and

Numerical and Experimental Investigation of the Performance of Dynamic Wing for Augmenting Ship Propulsion in Head and Quartering Seas

open access: yesJournal of Marine Science and Engineering, 2021
Flapping-foil thrusters arranged at the bow of the ship are examined for the exploitation of energy from wave motions by direct conversion to useful propulsive power, offering at the same time dynamic stability and reduction of added wave resistance.

The NOMAD system : expectation-based detection and correction of errors during understanding of syntactically and semantically ill-formed text [PDF]

open access: yes, 1983
Most large text-understanding systems have been designed under the assumption that the input text will be in reasonably "neat" form (for example, newspaper stories and other edited texts).

Leveraging synthetic imagery for collision-at-sea avoidance

open access: yes, 2018
Maritime collisions involving multiple ships are considered rare, but in 2017 several United States Navy vessels were involved in fatal at-sea collisions that resulted in the death of seventeen American Servicemembers.

Linear time-domain strip method for ship motion prediction

open access: yesZhongguo Jianchuan Yanjiu, 2019
[Objectives] In order to study the nonlinear strip method for prediction of ship motions in waves, this paper develops a linear time-domain strip method to make a preliminary exploration.[Methods] Under the assumptions of strip theory,the boundary ...

LyGDI, a novel SHIP-interacting protein, is a negative regulator of FcγR-mediated phagocytosis. [PDF]

open access: yesPLoS ONE, 2011
SHIP and SHIP-2 are inositol phosphatases that regulate FcγR-mediated phagocytosis through catalytic as well as non-catalytic mechanisms. In this study we have used two-dimensional fluorescence difference gel electrophoresis (DIGE) analysis to identify ...

Time domain analysis of ship motion and wave loads by boundary integral equations [PDF]

open access: yes, 2000
In this presentation, we like to discuss some aspects of a more general computational algorithm for the prediction of ship motion and loads induced by the interaction with wave systems.

Ship Wake Detection in SAR Images via Sparse Regularization [PDF]

open access: yes, 2019
In order to analyse synthetic aperture radar (SAR) images of the sea surface, ship wake detection is essential for extracting information on the wake generating vessels.
