Pressure projection is the single most computationally expensive step in an unsteady incompressible fluid simulation. This work demonstrates ability of data-driven methods to accelerate approximate solution Poisson equation at heart pressure projection. Geometric Multi-Grid are identified as linear convolutional encoder–decoder networks and a smoother developed using automatic differentiation o...

Many real-world planning problems require sophisticated reasoning about numeric resources, including sharing of resources by different actions. Constraintbased planners offer machinery to represent complex constraints and dependencies between actions. However, such planners usually consider a single partial plan at a time, and limit themselves with finding a feasible solution. Alternatively, pl...

The unprecedented growth of available spatial data at geographically distributed locations coupled with the emergence of grid computing provides a strong motivation for designing a spatial grid which supports fast data retrieval and allows its users to transparently access data of any location from anywhere. This calls for efficient search and loadbalancing mechanisms. This paper focusses on dy...

Grid technologies and infrastructures facilitate distributed resource sharing and coordination in dynamic, heterogeneous, multi-institutional environments. A replica catalog is a Grid component that keeps replica locations of data objects and provides location transparency to data access. Replica selection is of great importance to data-intensive scientific computing targeted by many data Grid ...

The ‘theorise-inquire’ technique is described, which supports the testing of both experts’ hunches and the quality of data sources. This technique is useful for the identification of data sources and data gaps by domain experts. We describe and illustrate the use of group contrasts, an analysis technique that allows an expert to explore and interpret repertory grids interactively to find signif...
