An Improved VO Method for Collision Avoidance of Ships in Open Sea

open access: yesJournal of Marine Science and Engineering
In order to effectively deal with collisions in various encounter situations in open water environments, a ship collision avoidance model was established, and multiple constraints were introduced into the velocity obstacle method, a method to determine ...

A new model for solution of complex distributed constrained problems

open access: yes, 2009
In this paper we describe an original computational model for solving different types of Distributed Constraint Satisfaction Problems (DCSP). The proposed model is called Controller-Agents for Constraints Solving (CACS). This model is intended to be used

Waveform-level time-domain simulation comparison study of three shipboard power system architectures [PDF]

open access: yes, 2012
Detailed waveform-level modeling and simulation of three alternative shipboard power system architectures is presented herein. The three system architectures are based on conventional 60Hz medium-voltage ac (MVAC), higherfrequency 240Hz medium-voltage ac

A Noise-Robust Method with Smoothed \ell_1/\ell_2 Regularization for Sparse Moving-Source Mapping

open access: yes, 2016
The method described here performs blind deconvolution of the beamforming output in the frequency domain. To provide accurate blind deconvolution, sparsity priors are introduced with a smooth \ell_1/\ell_2 regularization term. As the mean of the noise in

A Fully Nonlinear, Dynamically Consistent Numerical Model for Ship Maneuvering in a Seaway

open access: yesModelling and Simulation in Engineering, 2011
This is the continuation of our research on development of a fully nonlinear, dynamically consistent, numerical ship motion model (DiSSEL). In this paper we report our results on modeling ship maneuvering in arbitrary seaway that is one of the most ...

Time Domain Simulation of Ship Motion in Irregular Oblique Waves

open access: yesJournal of Applied Fluid Mechanics, 2020
Ship harmonic motion is an important and practical characteristic in ship design and performance evaluation. The development and optimization of hull-form, ship’s dynamic effects, seakeeping performance, and motion control, all require the motion data ...
