Abstract: Cooperative obstacle avoidance of multiple unmanned surface vessels (multi-USV) is an important issue in unmanned vessel safety. This study aims to solve dynamic safety collision avoidance problems, especially decision ...

Abstract: Ship trajectory prediction plays an important role in ensuring ship safety; through accurate ship positioning, the future trajectory of ships and their encounter time and location can be obtained, which facilitates the ...

Abstract: This study proposes a path planning algorithm for maritime navigation that combines global trajectory extraction from a ship’s automatic identification system (AIS) data with local dynamic collision avoidance using the ...

Abstract: The rapid development of the shipping industry and the increasingly complex maritime traffic pose potential risks, potentially leading to serious accidents and substantial economic losses. Identifying seafarer fatigue is ...

Abstract: Public resources such as transportation, hospitals, parks, and schools are important factors in housing prices. However, studies on property value have mainly concentrated on transportation, and few studies have focused ...

Abstract: Urban green space distribution has been extensively investigated; however, few studies have examined how these distributions are linked to anthropogenic activities at very fine scales. Here, the authors investigated the ...
