Seabed Surveillance and Underwater Structures Inspection with Remotely Operated Vehicle − Power Ray

The marine ecosystem is necessary to be monitored as it is exposed to externalities and pollutants that affect biodiversity and the state of the underwater structures. There is a demand for a better, more dynamic, and safe monitoring approach to underwater research and inspection. The unmanned underwater vehicles are becoming a reachable and intuitive tool for underwater inspection, such as for the inspection of the marine hull of vessels, bridges, foundations, piers, pylons, and other support structures in ports. The main advantage of the use of the remotely operated underwater drone is cost and time-efficiency, as they allow to obtain information in a fast and safe way in real-time. In this paper we investigate the possibility of the use of a remotely operated underwater drone Power Ray for seabed observation and underwater structures inspection. It describes the re-sults of the field research collected from the use of low-cost underwater drone Power Ray. The data collected with an underwater drone presents footages of different underwater structures and areas in order to document the seabed state and underwater structures. Additionally, this article provides an overview of the problems in underwater inspection and monitoring, and possibilities offered by remotely operated vehicle Power Ray in solv-ing them. The results of the paper are not unique to working with a low-cost drone, but are illustrative of the challenges and problems that new users are likely to encounter when using this technology

Survey on video anomaly detection in dynamic scenes with moving cameras

The increasing popularity of compact and inexpensive cameras, e.g.~dash cameras, body cameras, and cameras equipped on robots, has sparked a growing interest in detecting anomalies within dynamic scenes recorded by moving cameras. However, existing reviews primarily concentrate on Video Anomaly Detection (VAD) methods assuming static cameras. The VAD literature with moving cameras remains fragmented, lacking comprehensive reviews to date. To address this gap, we endeavor to present the first comprehensive survey on Moving Camera Video Anomaly Detection (MC-VAD). We delve into the research papers related to MC-VAD, critically assessing their limitations and highlighting associated challenges. Our exploration encompasses three application domains: security, urban transportation, and marine environments, which in turn cover six specific tasks. We compile an extensive list of 25 publicly-available datasets spanning four distinct environments: underwater, water surface, ground, and aerial. We summarize the types of anomalies these datasets correspond to or contain, and present five main categories of approaches for detecting such anomalies. Lastly, we identify future research directions and discuss novel contributions that could advance the field of MC-VAD. With this survey, we aim to offer a valuable reference for researchers and practitioners striving to develop and advance state-of-the-art MC-VAD methods.Comment: Under revie

Impact of Artificial Intelligence on Strategic Stability and Nuclear Risk : Volume II East Asian Perspectives.

Artificial intelligence (AI) is not only undergoing a renaissance in its technical development, but is also starting to shape deterrence relations among nucleararmed states. This is already evident in East Asia, where asymmetries of power and capability have long driven nuclear posture and weapon acquisition. Continuing this trend, integration of AI into military platforms has the potential to offer weaker nuclear-armed states the opportunity to reset imbalances in capabilities, while at the same time exacerbating concerns that stronger states may use AI to further solidify their dominance and to engage in more provocative actions. This paradox of perceptions, as it is playing out in East Asia, is fuelled by a series of national biases and assumptions that permeate decision-making. They are also likely to serve as the basis for AI algorithms that drive future conventional and nuclear platforms

Tracking the Fine Scale Movements of Fish using Autonomous Maritime Robotics: A Systematic State of the Art Review

This paper provides a systematic state of the art review on tracking the fine scale movements of fish with the use of autonomous maritime robotics. Knowledge of migration patterns and the localization of specific species of fish at a given time is vital to many aspects of conservation. This paper reviews these technologies and provides insight into what systems are being used and why. The review results show that a larger amount of complex systems that use a deep learning techniques are used over more simplistic approaches to the design. Most results found in the study involve Autonomous Underwater Vehicles, which generally require the most complex array of sensors. The results also provide insight into future research such as methods involving swarm intelligence, which has seen an increase in use in recent years. This synthesis of current and future research will be helpful to research teams working to create an autonomous vehicle with intentions to track, navigate or survey

InfoSwarms: Drone Swarms and Information Warfare

Drone swarms, which can be used at sea, on land, in the air, and even in space, are fundamentally information-dependent weapons. No study to date has examined drone swarms in the context of information warfare writ large. This article explores the dependence of these swarms on information and the resultant connections with areas of information warfare—electronic, cyber, space, and psychological—drawing on open-source research and qualitative reasoning. Overall, the article offers insights into how this important emerging technology fits into the broader defense ecosystem and outlines practical approaches to strengthening related information warfare capabilities
