Arctic navigation risk assessment using ICESat-2 and GIS-Based AHP

International Journal of Applied Earth Observations and Geoinformation
The Arctic Ocean is among the world’s most hazardous maritime regions, where sea ice, uncharted bathymetry, and limited emergency infrastructure threaten vessel safety. Recent advances in remote sensing now provide critical spatial data that can mitigate

Model tests of an icebreaking tanker in broken ice

International Journal of Naval Architecture and Ocean Engineering, 2019
Several model-scale tests with a ship model have been performed in the ice tank of the Marine Technology Group in the Aalto University. The ship model of ice going tanker Uikku was mounted rigidly to the main carriage and towed through ice fields.

Notes on Icebreaker

, 2021
Icebreaker [1] is new research from MSR that is able to achieve state of the art performance on inference in which there is inherent missing data. Using mutual information, Icebreaker is able to suggest which values in the data to impute for maximum benefit.

Icebreakers and Anxiety

WRIT: Journal of First-Year Writing, 2020
This project is based on a personal experience of feeling anxious during icebreakers. It is also incorporated the idea of shyness and sociability and related these to anxiety in general and during icebreakers. A survey was created with questions based on a previous survey, common symptoms of anxiety, and other personal symptoms with anxiety during ...

A Numerical Simulation Method for Investigating the Fluid–Structure–Ice Coupling Mechanism of a Wedge Breaking through Ice into Water

Applied Sciences
We aimed to investigate the fluid–solid–ice coupling mechanism as structures break through ice into water. Using LS–DYNA finite element software, a numerical simulation method is established, based on the ALE flow–solid coupling method, and the penalty ...
