The Bosporus Straits are among the most crowded and potentially dangerous, waterways in the world traversing urban areas of over 12 million people. Their narrow and winding shape, along with strong surface and counter deep water sea currents hinders the navigation. In this article, a queuing model of maritime traffic in the Bosporus Straits is presented. Physical characteristics of the waterway...

The crowd can provide a tremendous amount of data to help us understand the world around us. Data from social network sites, such as Twitter, allow us to implicitly mine data from the crowd, for example to understand different opinions on political issues, the important moments in an event, or the sentiment around particular brands. Other systems, such as CreekWatch, ask members of the crowd to...

ontemporary ethical theory begins with G. E. Moore (1873–1958). Moore opened up new issues for consideration and altered the focus of ethical discussion. Much of twentieth-century analytic ethics, at least until recently, treated issues that were raised by Moore or by philosophers responding either to him or to other respondents. Although analytic ethical philosophers discussed many questions t...

The vulnerabilities of global navigation satellite systems (GNSSs) to radio frequency jamming and spoofing have attracted significant research attention. In particular, the large-scale incidents that occurred in South Korea substantiate practical importance implementing a complementary system. This letter briefly summarizes efforts deploy an enhanced long-range (eLoran) system, which is terrest...

Abstract This paper describes the choice of Flemish waterway authority – De Vlaamse Waterweg for a new vision on remote operation its inland infrastructure. From now on, control is default mode. As 2019, was approved to remotely all our movable structures (ca.330) by 2032 from 3 centres. The innovative aspect that they will function as fully interconnected meshed network and can be used back-up...

Ship collision is a major type of accident in waterway transportation, with considerable annual occurrence that always causes serious casualty. Among the evidences that can facilitate the investigation, AIS data recorded during the context of the collision are highly informative. This paper exploits the contextual AIS data in a coupled spatial–temporal perspective. With the discrete waypoints s...

The Shipboard Automatic Identification System (AIS) is crucial for navigation safety and maritime surveillance, data mining and pattern analysis of AIS information have attracted considerable attention in terms of both basic research and practical applications. Clustering of spatio-temporal AIS trajectories can be used to identify abnormal patterns and mine customary route data for transportati...
