Faster, Better, Cheaper: Solutions to the Atmospheric Shipping Emission Compliance and Attribution Conundrum

Global concerns regarding air quality have over the past decade led to the introduction of regulations by the International Maritime Organisation curbing the emissions of sulphur and nitrogen oxides (SOx, NOx). These limits were implemented initially in so-called “emission control areas”, defined where the density of shipping activity combines...

A Reference Spectrum Model for Estimating Source Levels of Marine Shipping Based on Automated Identification System Data

Underwater sound mapping is increasingly being used as a tool for monitoring and managing noise pollution from shipping in the marine environment. Sound maps typically rely on tracking data from the Automated Information System (AIS), but information available from AIS is limited and not easily related to vessel noise emissions. Thus, robust...

Multi-sensor information extraction and combination in a large harbor surveillance experiment

Review of antenna technologies for very high frequency Data Exchange Systems

Analyzing Vessel Behavior Using Process Mining

In the maritime domain, electronic sensors such as AIS receivers and radars collect large amounts of data about the vessels in a certain geographical area. We investigate the use of process mining techniques for analyzing the behavior of the vessels based on these data. In the context of maritime safety and security, the goal is to support...

Threats and Vulnerabilities of RFID and Beyond

This chapter discusses both security and privacy threats to RFID systems, in a balanced way. We first outline the general architecture of an RFID system, the stakeholders managing the different components, and identify the specific properties of RFID systems relevant for privacy and security. We then discuss threats aimed at the tag itself, at...

Inference of vessel behaviour in the Dutch Coastal North Sea

About one year of coastal AIS (Automatic Identification System) data are analysed for vessel behaviour. The data are obtained from thousands of vessels along the Dutch North Sea coast including the entrance to the main port of Rotterdam. Vessel behaviour is described by a number of basic indicators that can be obtained directly from the AIS...

Electromagnetic interference from radio frequency identification inducing potentially hazardous incidents in critical care medical equipment

Context: Health care applications of autoidentification technologies, such as radio frequency identification (RFID), have been proposed to improve patient safety and also the tracking and tracing of medical equipment. However, electromagnetic interference (EMI) by RFID on medical devices has never been reported. Objective: To assess and classify...

Ship detection with Envisat's alternating polarization mode

A ship detection algorithm is developed that uses Envisat ASAR imagery in alternating polarisation mode. From airborne data it is shown that of the two co-polarisations, HH is preferred over VV because of a larger ship-to-clutter ratio. Combining the HH and HV images of alternating polarisation mode, it is found that the correlation between the...

AIS in naval environment

From the first of July 2002 the Automatic Identification System (AIS) is introduced as part of the carriage requirements for all ships of 300 CT and larger, falling under the SOLAS convention. An introductory phase is planned to equip these ships with an AIS mobile station. Every ship with AIS, at sea as well as in a VTS environment, will...
