Numerical Simulation of an Icebreaker Ramming the Ice Ridge

open access: yesJournal of Marine Science and Engineering
During polar navigation, icebreakers frequently encounter ice ridges, which can significantly reduce navigation efficiency and even pose threats to structural safety. Therefore, studying the ramming of ice ridges by the icebreaker is of great importance.

Icebreaking ship

open access: yesEos, Transactions American Geophysical Union, 1990
The U.S. Antarctic Program will have a new ship for working in polar waters by early 1992. It will be the first U.S. ship with icebreaking capability dedicated to scientific research. The Polar Duke, currently leased by the National Science Foundation, which manages the program, is ice‐strengthened but cannot break ice.NSF announced in February that an

The Responsibiligated Status: Exploring the Experiences of Hearing Children With Deaf Parents

open access: yesChild &Family Social Work, EarlyView.
ABSTRACT An individual with a disability influences every member of a family. While research on families with children with disabilities is extensive, studies focusing on families with parents with disabilities remain limited. A common situation in the deaf community is a family with deaf parents and hearing children.

Prediction of ship resistance in level ice based on empirical approach

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2017
A semi-empirical model to predict ship resistance in level ice based on Lindqvist's model is presented. This model assumes that contact between the ship and the ice is a case of symmetrical collision, and two contact cases are considered.

Nuclear Propelled Vessels and Neutrino Oscillation Experiments [PDF]

open access: yes, 2002
We study the effect of naval nuclear reactors on the study of neutrino oscillations. We find that the presence of naval reactors at unknown locations and times may limit the accuracy of future very long baseline reactor-based neutrino oscillation ...

Transformative Learning and Participatory Approaches With Youth: A Discussion on Distinctions

open access: yesChildren &Society, EarlyView.
ABSTRACT Since the 1990s, participatory approaches have been regarded as effective and ethical in research and policy work involving children and youth. Recently, the term ‘transformation’ has gained traction in Childhood Studies. This article explores Transformative Learning (TL) methodology, which was introduced in the 1970s for adult education but ...

Prediction of ice resistance of icebreaker during continuous icebreaking

open access: yesZhongguo Jianchuan Yanjiu, 2021
ObjectiveIn order to accurately assess the ice resistance experienced by an icebreaker during continuous icebreaking when sailing in a level ice zone, and understand the characteristics of different prediction methods, this paper uses the empirical formula method, numerical simulation method and ship model test method to evaluate an icebreaker's ...
