Improved situation awareness is a key enabler of better emergency preparedness and response (EP&R). This paper describes two important challenges: information interoperability and provenance. The former enables meaningful information exchange across separately developed systems, while the latter gives users context that helps them interpret shared information and make trust decisions. We present...
This demonstration presents Galaxy, a schema manager that facilitates easy and correct data sharing among autonomous but related, evolving data sources. Galaxy reduces heterogeneity by helping database developers identify, reuse, customize, and advertise related schema components. The central idea is that as schemata are customized, Galaxy maintains a derivation graph, and exploits it for data exchange,...
This demonstration shows how semantic schema matching technology is being incorporated into the BEA AquaLogic data services platform. Specifically, it demonstrates how the manually-intensive task of authoring a correct and complete integration query is enhanced by semantic guidance. It also highlights the pluggable architecture used to incorporate semantic match knowledge into ALDSP by showing the...
A key aspect of any data integration endeavor is establishing a transformation that translates instances of one or more source schemata into instances of a target schema. This schema integration task must be tackled regardless of the integration architecture or mapping formalism. In this paper we provide a task model for schema integration. We use this breakdown to motivate a workbench for schema...
A high-pressure test wheel for flow simulation has been used to study gas hydrate formation and inhibition in hydrocarbon gas-water-oil systems. The stainless steel wheel, which could be rotated in a temperature controlled chamber at a constant angular velocity, was equipped with pressure (0-150bar), temperature (-10-150 degrees C) and torque sensors. The sensor signals were transfered to a real...
