SUMMARY A contract network extends the concept of a contract path to address the problem of loop flow and congestion in electric power transmission systems. A contract network option provides a well defined, internally consistent framework for assigning long-term capacity rights to a complicated electric transmission network. The contract network respects(More)
Haase This paper describes the architecture, implementation and evaluation of NetSerf, a program for finding information archives on the Internet using natural language queries. NetSerf’s query processor extracts structured, disambiguated representations from the queries. The query representations are matched to hand-coded representations of the archives(More)
This article argues for the growing importance of quality metadata and the equation of that quality with precision and semantic grounding. Such semantic grounding requires metadata that derives from intentional human intervention as well as mechanistic measurement of content media. In both cases, one chief problem in the automatic generation of semantic(More)
The transition of print media into a digital form allows the tailoring of news for different audiences. This thesis presents a new approach to tailoring called augmenting. Augmenting makes articles more informative and relevant to the reader. The PLUM system augments news on world-wide natural disasters that readers often find remote and irrelevant. Using(More)
Oligonucleotides have been extensively studied for their potential as therapeutic agents. Phosphorothioate oligonucleotides have been demonstrated to be particularly useful due to their stability against nucleases, their ability to be internalized by many cell types, and the ease with which they hybridize with target mRNA. These compounds have previously(More)
In this work we address the problem of tracking objects in a complex, dynamic scene. The objects are non-rigid and difficult to model geometrically. Their motion is erratic and they change shape rapidly between frames sampled at 30 frames per second. The objects have low spatial resolution, and the video used for tracking was taken with a panning and(More)
