Efficient Integration of Old and New Research Tools for Automating the Identification and Analysis of Seismic Reference Events

65339 The DOE uses a variety of stand-alone computer programs to analyze and identify seismic events for the monitoring of a nuclear test-ban. However, these separate programs do not communicate adequately with one another so that they can exchange data easily, and newly developed analysis programs cannot communicate with them directly. A new software architecture is needed to facilitate data flow among these legacy and new codes so that the results of one program can be sent to another and so that the programs can make function calls to one another. This project will develop two data communications protocols to permit data to be exchanged directly among seismic analysis codes and allow one program to make calls to another. In Phase I, an interactive graphics program for seismogram data display and measurement was modified by adding an interface that allows data communications that are compliant with Common Object Request Broker Architecture (CORBA). A Java-language program for platform-independent interactive graphics display and for certain analysis operations on seismograms was similarly adapted with a CORBA interface. Now, the two programs can exchange data within a single computer or across a network. In Phase II, the CORBA interface will be further modified to transmit data segments for specialized processing by seismic analysis programs. Corresponding CORBA interfaces will be added to those codes, and an overall integration architecture will be deployed. A parallel effort will be directed at using ¿Web services¿ protocols to allow these codes to communicate across an intranet. Commercial Applications and Other Benefits as described by the awardee: A flexible architecture for integrating research tools for seismic reference events analysis should be applicable to the mission of the U.S. Air Force Technical Applications Center, the International Data Center of the Comprehensive Test Ban Treaty Organization, and the National Data Centers of treaty signatories. Commercial customers include business-to-business data exchange among, for example, earthquake engineering and insurance companies and the oil and gas exploration industry.
