Overlay networks are virtual communication structures that are logically “laid over” underlying hosting networks such as the Internet. They are implemented by deploying application-level topology maintenance and routing functionality at strategic places in the hosting network [1, 2]. In terms of dependability, most overlays offer proprietary “self-repair” functionality to recover from situation...

The X-Bone dynamically deploys and manages Internet overlays to reduce their configuration effort and increase network component sharing. The X-Bone discovers, configures, and monitors network resources to create overlays over existing IP networks. Overlays are useful for deploying overlapping virtual networks on shared infrastructure and for simplifying topology. The X-Bone extends current ove...

The high replacement costs of aircraft gas turbine blades and vanes have created a fast-growing, highly-specialized segment of the aircraft repair industry. The economic rationale for repair in lieu of replacement is prima facie. The metallurgical rationale is less certain, but satisfactory flight performance over the past twenty-five years at least attests to the technical adequacy of blade an...

Peer-to-Peer index structures distributed and managed over the planet, commonly known as structured overlays (e.g., Distributed Hash Tables) have been touted to play the role of a fundamental building block for internet-scale distributed systems. Traditional designs consider incremental or possibly even parallelized construction of a single overlay, which implicitly assumes global control and c...

1.0 Introduction It is now reasonably well established that reinforced concrete (RC) structural elements can be strengthened/retrofitted/repaired by bonding high-strength fibre reinforced polymer (FRP) composites. Such reasons include steel reinforcement corrosion, construction flaws, change in loading or structure usage, or damage from impact or seismic events. Traditional methods of repair ca...
