The ship sailing performance while ramming ice is difficult to predict under complex ice conditions. To provide an accurate prediction of the ship sailing performance during the ramming operation under thick level ice conditions, we constructed a model ship in an ice tank to simulate a polar ...

A comparative analysis between the Decision Tree and Random Forest machine learning algorithms, evaluated using performance metrics such as F1-score, revealed that the latter is more effective at predicting pallet collapse. This study is pioneering in identifying new critical predictive variables, ...
However, when the value of shrinkage parameter reaches to a certain level, the model performance begins to deteriorate. Taking DWL subway station as an example, the model performance with C = 1 becomes better as the shrinkage parameter value decreases from ξ = 0.10 to ξ = 0.01. However, ...
Ship performance in Arctic watersShip stuck in iceProbabilistic risk assessmentBayesian belief networksRecently, the melting of sea ice due to global warming has made it possible for merchant ships to navigate through Arctic Waters. However, Arctic Marine Transportation System remains a very demanding,...
A hierarchical Gaussian process model was used to study how the load distribution parameters change in different conditions. The operational conditions are described by ship speed, whereas the ice conditions varied from thin, first-year ice, to thick, multiyear ice. Because of this variation, the ...
In this study, a Bayesian Network model is developed to predict the probability of ship besetting in ice in a convoy operation along the Northern Sea Route (NSR). The model focuses on the first-assisted ship and is based on expert elicitation. Correspondingly, four scenarios that may result ...
3.1.1. The Study Area The first road project concerned part of the planned A1 motorway section in Pyrzowice; the section is located along the northern border of the Silesian Voivodship and is about 75 km long (Figure 2). The field research involved a strip of land with a width of 500 ...
