Research on Extraction Method of Multiple Narrow Channel Vessel Trajectory Feature in Yangtze River Based on VITS Data

open access: yesJournal of Advanced Transportation, Volume 2022, Issue 1, 2022., 2022
Vessel big data play a significant role in understanding vessel behaviors and thus facilitating the prosperity of waterway transportation. However, relevant research regarding vessel trajectory recognition in a broad range of narrow channels still lacks, especially using VITS data.

A Novel Ship‐Ship Distance Model in Restricted Channel via Gaussian‐TRR Identification

open access: yesMathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
Very large ships are crucial cargo ships that are relatively difficult to manoeuvre, and ship‐ship distance is a vital manoeuvring parameter in restricted channel. To ensure ship safety and improve scheduling efficiency, this study established a ship‐ship distance model in restricted channel by ship manoeuvring motion simulation, collision detection ...

Evaluating air emission inventories and indicators from cruise vessels at ports [PDF]

open access: yes, 2017
This paper provides an estimation of air emissions (CO2, NOX, SOX and PM) released by cruise vessels at the port level. The methodology is based on the Bfull bottom-up^ approach and starts by evaluating the fuel consumed by each vessel on the basis of

Tracking of a Manoeuvering Target Ship using Radar Measurements

open access: yesIndian Journal of Science and Technology, 2015
For on sea water measurements of range on bearing in naval operations various types of Kalman filters including extended Kalman filter have been used. In this paper ,input estimation techniques applied normally to in air applications are applied to on sea measurements using chi – square distribution random sequence residual techniques.

Building Flexible Organizations for Fast-moving Markets [PDF]

open access: yes, 1997
By considering flexibility as a valuable strategic option in turbulent environments, this article distinguishes four types of effective response to strategic change. From this typology different trajectories of revitalization are derived. On the basis of

Iterated Nonlinear Control of Ship's Manoeuvring Models [PDF]

open access: yes, 2013
This paper addresses the control design for a nonlinear vessel manoeuvring model. The authors consider a highly nonlinear vessel 4 DOF model. The proposed control algorithm consists of a combination of an iteration technique that approximates the ...
