The surveillance and inspection of underwater installations such as telecommunication cables are currently carried out by trained operators who, from the surface, guide a Remotely Operated Vehicle (ROV) with cameras mounted over it. This manual visual control is, however, a very tedious job that tends to fail if the operator looses concentration. This paper describes a tracking system for underwater...
One of the key challenges related to the grid environment is to efficiently use the storage resources of compute nodes. Therefore, we have developed the ViSaGe solution which features VisageFS - a POSIX-compliant wide-area file system, VCCC - a distributed lock mechanism, and VRT - a storage virtualization layer. In this paper, we present the VisageFS translucentdirectory property which enables a...
In recent years, anytime algorithms have shown to be a good solution for planning a path in domains with severe restrictions regarding the time for deliberation. They typically operate by quickly finding a highly suboptimal path first, and then improving it until the available time runs out. In this paper, we propose a novel anytime approach called ABUG that performs much more efficiently than the...
