    Understanding earthquake behavior is crucial for predicting earthquakes' effects. One way of understanding long-term earthquake behavior is through simulation. Virtual California is a program developed to generate ensembles of earthquakes in a specified fault system. The theory underlying the program, some recent results, and several optimizations used to improve performance are presented. View full abstract»

    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 and E-Decider. View full abstract»

    Advances in understanding earthquakes require the integration of models and multiple distributed data products. Increasingly, data are acquired through large investments, and utilizing their full potential requires a coordinated effort by many users, independent researchers, and groups who are often distributed both geographically and by expertise.

    Earthquakes don't have precursors that can be reliably used for earthquake prediction. However, distributions of earthquakes (seismicity) can be used to forecast an earthquake hazard. These distributions in space, time, and magnitude can be studied in a variety of ways. The Regional Earthquake Likelihood Models (RELM) test compares the different approaches. View full abstract»

    A geodesic distance-based approach synthesizes natural facial animations using radial basis function (RBF) interpolation. The approach consists of two parts: the geodesic distance calculation and the geodesic distance-based RBF interpolation. The method works in real time, which is important in computer games and online chatting. View full abstract»

    Gravitational search algorithms (GSAs) yield high performances in solving optimization problems, but require time-consuming computations for the total force on each mass which makes the speed of optimization very low. However, replacing a GSA's sequential approach with a multiagent system could improve a GSA's speed considerably while maintaining the high performance level. View full abstract»

    The exploration and visualization of large volumetric medical datasets from high-resolution computed tomography (CT) and medical resonance imaging (MRI) medical images are slow in rendering speed because of the large amount of data. Distance-based methods can address such issues, based on GPU volume raycasting and the idea of focus + context. View full abstract»

    Single instruction, multiple data (SIMD) extensions have been a feature of choice for processor manufacturers for a couple of decades. Designed to provide significant accelerations, they require expertise, the use of potentially fragile compiler support, or vendor-specific libraries. Here, a C++ template library called Boost.SIMD is presented that simplifies the exploitation of SIMD hardware withi... View full abstract»
