This paper describes a metadata interchange approach for semi-automated integration of heterogeneous distributed databases. Our system prototype uses distributed metadata to generate a GUI tool for a meta-user (who does the metadata integration) to describe mappings between master and local databases by assigning index numbers and specifying conversion(More)
Peer-to-peer computing is a term used to describe the current trend toward utilizing the full resources available within a widely distributed network of nodes with increasing computational power. These resources include the exchange of information, processing cycles, cache storage, and disk storage for files. Routing, locating and transmitting of resources,(More)
Experience suggests that fully automated schema matching is infeasible, especially when n-to-m matches involving semantic functions are required. It is therefore advisable for a matching algorithm not only to do as much as possible automatically, but also to accurately identify positions where user input is necessary. Our matching algorithm combines several(More)
The mould polishing is a complex material removal process under various polishing conditions. The process parameters (polishing pressure, tool speed, feed rate, polishing times, pose angle, etc.) and material parameters (workpiece material, abrasive tool material) have effects on surface roughness. In this paper, a new surface roughness model based on(More)
