The X-Bone dynamically deploys and manages Internet overlays to reduce 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 overlay m...

Concrete overlays are a growing solution in the United States for pavement rehabilitation and preservation. Many different overlay types designs can be used based on existing conditions to achieve variety of design goals. Recent performance studies have indicated that concrete capable providing an extended service life 35 years or more. However, intended may shorter, some cases, experience earl...

Many small organizations lack the expertise and resources to conduct usability evaluations of their websites. Social Overlays, presented here, is a new system that allows a community of users to collectively improve their website. Social Overlays enables end–users to identify and repair common user interface problems through creating “overlays” on web pages as part of their regular use, thereby...

In this paper, we evaluate the performance of an iterative registration algorithm for position estimation of Unmanned Ground Vehicles (UGVs) operating in unstructured environments. Field data obtained from trials on UGVs traversing undulating outdoor terrain is used to quantify the performance of the algorithm in producing continual position estimates. These estimates are then compared with tho...

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...

This paper develops a theoretical and technological foundation for a new kind of interactive map, the augmented scene, that overlays acquired imagery of the environment on a perspective model of the surface in real time. The ground position and viewing direction of users are computed automatically, freeing them from the map orientation process. We define augmented scenes, propose some applicati...
