high speed trains are an indispensable part of rapid transportation systems in many countries. as the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

Since the spread of coronavirus disease 2019 (COVID-19) pandemic, transportation cargo by ship has been seriously impacted. In order to prevent and control maritime COVID-19 transmission, it is great significance track predict sailing behavior. As nodes networks, ports call can reflect behavior ship. Accurate hierarchical division help clarify navigation law ships with different types scales. F...

Over the past two decades or so, Multi-Word Expressions (MWEs; also called Multi-word Units) have been an increasingly important concern for Computational Linguistics and Natural Language Processing (NLP). The term MWE has been used to refer to various types of linguistic units and expressions, including idioms, noun compounds, phrasal verbs, light verbs and other habitual collocations. However...

We consider the problem of finding a route that minimises the expected sailing time between two points on the ocean under uncertain weather conditions. This has applications in long distance offshore yacht racing. The uncertainty in the weather is modelled by a branching scenario tree that captures the serial correlation inherent in the evolution of weather systems over time. The stochastic sol...

monkey with vision occluded obtain information about its own motor activities, as would be necessary, for example, when learning new movements? In this regard it is worth considering the possibility of the operation of central feedback mechanisms. Intracentral loops located appropriately could provide a means of monitoring central efferent activity before it has emerged into the periphery. Seve...
