Piracy on the high seas is a problem of world-wide concern. In response to this threat, the US Navy has developed a visualization tool known as the Pirate Attack Risk Surface (PARS) that integrates intelligence data, commercial shipping routes, and meteorological and oceanographic (METOC) information to predict regions where pirates may be present and where(More)
In this paper, the problem of online anomaly detection in multi-attributed, asynchronous data from a large number of individual devices is considered. It has become increasingly common for many services, such as video-on-demand (VOD), to have connected customers where hundreds of millions of subscribers access a cluster of content servers for online(More)
Major challenges anticipated by future mission planners comprise automated processing, interpretation, and development of intelligent decisions using large volumes of dynamically evolving structured and unstructured data, while simultaneously decreasing the time necessary to plan and replan. Motivated by the need to seamlessly integrate automated(More)
Coordination among maritime assets is crucial for reducing task latencies and enabling the effectiveness and success of the mission. Specifically, determining when the assets are dispatched to task locations, optimizing how the assets traverse to the task location, and how much time the assets wait at various intermediate points on the way to task location(More)
Motivated by the Navy’s emphasis on networked planning capabilities in maritime operations centers (MOC), we have developed an agent-based multi-level resource allocation model that takes high level commands from the human planners and then dynamically allocates the lower-level assets and processes tasks to accomplish the mission objectives. The agent-based(More)
UAVs are becoming ubiquitous due to their high-risk mission acceptance and ultra-long endurance capabilities. However, because a significant subset of UAVs have limited payload capacity and sensor ranges, teams of UAVs are often required to operate cooperatively in executing specific tasks (e.g., time-critical complex surveillance tasks requiring multiple(More)
