Automatic Control and Routing of Marine Vessels

Due to the intensive development of the global economy, many problems are constantly emerging connected to the safety of ships’ motion in the context of increasing marine traffic. These problems seem to be especially significant for the further development of marine transportation services, with the need to considerably increase their efficiency and reliability. One of the most commonly used approaches to ensuring safety and efficiency is the wide implementation of various automated systems for guidance and control, including such popular systems as marine autopilots, dynamic positioning systems, speed control systems, automatic routing installations, etc. This Special Issue focuses on various problems related to the analysis, design, modelling, and operation of the aforementioned systems. It covers such actual problems as tracking control, path following control, ship weather routing, course keeping control, control of autonomous underwater vehicles, ship collision avoidance. These problems are investigated using methods such as neural networks, sliding mode control, genetic algorithms, L2-gain approach, optimal damping concept, fuzzy logic and others. This Special Issue is intended to present and discuss significant contemporary problems in the areas of automatic control and the routing of marine vessels

Training of Crisis Mappers and Map Production from Multi-sensor Data: Vernazza Case Study (Cinque Terre National Park, Italy)

This aim of paper is to presents the development of a multidisciplinary project carried out by the cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action). The goal of the project was the training in geospatial data acquiring and processing for students attending Architecture and Engineering Courses, in order to start up a team of "volunteer mappers". Indeed, the project is aimed to document the environmental and built heritage subject to disaster; the purpose is to improve the capabilities of the actors involved in the activities connected in geospatial data collection, integration and sharing. The proposed area for testing the training activities is the Cinque Terre National Park, registered in the World Heritage List since 1997. The area was affected by flood on the 25th of October 2011. According to other international experiences, the group is expected to be active after emergencies in order to upgrade maps, using data acquired by typical geomatic methods and techniques such as terrestrial and aerial Lidar, close-range and aerial photogrammetry, topographic and GNSS instruments etc.; or by non conventional systems and instruments such us UAV, mobile mapping etc. The ultimate goal is to implement a WebGIS platform to share all the data collected with local authorities and the Civil Protectio

Automatic Maritime Traffic Anomalous Behaviors Detection

Maritime traffic plays a very important role in the world economy, with over 90% of global trading done through naval transportation. The high amount of vessel traffic, mainly due to cargo transportation, leads to several new risks, threats, and concerns, such as increased criminal activity in the sea. The OVERSEE project is proprietary software developed by Crit ical Software and used by Marinha Portuguesa, Irish Coast Guard, and Papua New Guinea’s Coast Guard. The OVERSEE project displays vessel information in real-time through AIS messages, which are mandatory for most cargo vessels to report consistently. Anomaly de tection and behavior monitoring tools are computer-based systems that analyse real-time data to detect anomalous behaviors. This project aims to develop a solution capable of detecting anomalous behaviors committed by vessels using AIS messages, which will be re ported in real-time automatically via e-mail and the extant OVERSEE graphical interface. The solution is developed with the use of Long Short-Term Memory Recurrent Neural Net works, and a deeper analysis is provided to compare the obtained results with the ideal results. The network training and testing are done with real data, with cross-classification techniques to improve the trustworthiness of the algorithm, hence providing more accurate results.O tráfego marítimo desempenha um papel muito importante na economia mundial, com mais de 90% do comércio global feito por meio do transporte naval. O grande volume de tráfego de embarcações, principalmente devido ao transporte de cargas, leva a vários novos riscos, ameaças e preocupações, como o aumento da criminalidade no mar. O projeto OVERSEE é um software proprietário desenvolvido pela Critical Software e usado pela Marinha Portuguesa, Guarda Costeira Irlandesa e Guarda Costeira da Papua Nova Guiné. O projeto OVERSEE exibe informações da embarcação em tempo real por meio de mensagens AIS, cuja maioria das embarcações de carga são obrigadas a relatar num período de tempo regular. As ferramentas de detecção de anomalias e monitoramento de comportamento são sistemas baseados em computador que analisam dados em tempo real para detetar comportamentos anómalos. Este projeto visa desenvolver uma solução capaz de detetar comportamentos anómalos cometidos por embarcações por meio de mensagens AIS, que serão reportados em tempo real automaticamente via e-mail e interface gráfica existente do OVERSEE. A solução está desenvolvida com o uso de Redes Neurais Recorrentes1 de Memória-Curta de Longo Prazo2 . Uma análise mais profunda é fornecida para comparar os resultados obtidos com os resultados ideais. O treinamento e teste da rede são feitos com dados reais, com técnicas de classificação cruzada para melhorar a confiabilidade do algoritmo, fornecendo resultados mais precisos

The DARPA Model for Transformative Technologies

"The U.S. Defense Advanced Research Projects Agency (DARPA) has played a remarkable role in the creation new transformative technologies, revolutionizing defense with drones and precision-guided munitions, and transforming civilian life with portable GPS receivers, voice-recognition software, self-driving cars, unmanned aerial vehicles, and, most famously, the ARPANET and its successor, the Internet. Other parts of the U.S. Government and some foreign governments have tried to apply the ‘DARPA model’ to help develop valuable new technologies. But how and why has DARPA succeeded? Which features of its operation and environment contribute to this success? And what lessons does its experience offer for other U.S. agencies and other governments that want to develop and demonstrate their own ‘transformative technologies’? This book is a remarkable collection of leading academic research on DARPA from a wide range of perspectives, combining to chart an important story from the Agency’s founding in the wake of Sputnik, to the current attempts to adapt it to use by other federal agencies. Informative and insightful, this guide is essential reading for political and policy leaders, as well as researchers and students interested in understanding the success of this agency and the lessons it offers to others.
