We describe the architecture and implementation of the Solid Earth Research Virtual Observatory (SERVO)'s Complexity Computational Environment. We base our design on a globally scalable distributed " cyber-infrastructure, " or Grid, built around a Web Services-based approach consistent with the extended Web Service Interoperability (WS-I+) model. In order(More)
Development has boosted the GeoFEST system for simulating the faulted crust from a local desktop research application to a community model deployed on advanced cluster platforms, including an Apple G5, Intel P4, SGI Altix 3000, and HP Itaniam 2 clusters. GeoFEST uses unstructured tetrahedral meshes to follow details of stress evolution, fault slip, and(More)
STUDY DESIGN A retrospective review of all the surgically managed spinal fractures at the University of Missouri Medical Center during the 41/2-year period from January 1989 to July 1993 was performed. Of the 51 surgically managed patients, 46 were instrumented by short-segment technique (attachment of one level above the fracture to one level below the(More)
We propose to define, design, develop, deploy, and test a data semantics based system to provide interoperability for heterogeneous data in the earthquake science domain. We focus on the database management aspects of the work, including modeling the meaning of the data, providing for web service based access to heterogeneous data sources to scientists to(More)
Service-based geographic information system (GIS) technologies can enable an open-architecture cyberinfrastructure to provide standards-compliant data products and computing services for both earthquake research and disaster planning and response. Here, a service-based GIS framework is evaluated using examples from two earthquake science projects: QuakeSim(More)
—We describe the goals and initial implementation of the International Solid Earth Virtual Observatory (iSERVO). This system is built using a Web Services approach to Grid computing infrastructure and is accessed via a component-based Web portal user interface. We describe our implementations of services used by this system, including Geographical(More)
—We are developing simulation and analysis tools in order to develop a solid Earth Science framework for understanding and studying active tectonic and earthquake processes. The goal of QuakeSim and its extension, the Solid Earth Research Virtual Observatory (SERVO), is to study the physics of earthquakes using state-of-the-art modeling, data manipulation,(More)
The QuakeSim Problem Solving Environment uses a web-services approach to unify and deploy diverse remote data sources and processing services within a browser environment. Here we focus on the high-performance crustal modelling applications that will be included in this set of remote but in-teroperable applications. PARK is a model for unstable slip on a(More)
We studied the results of prolonged intravenous therapy with antibiotics through a central venous silicone-elastomer catheter that had been peripherally inserted in thirty-five orthopaedic patients. The catheters remained in place for an average of twenty-nine days (range, five to seventy-four days). The 20-gauge (one-millimeter-diameter) catheters used in(More)
Computer simulations will be key to substantial gains in understanding the earthquake process. Emerging information technologies make possible a major change in the way computers are used and data is accessed. An outline of a real-izable computational infrastructure includes standardization of data accessibility , harnessing high-performance computing(More)
