Time constraint is a key problem in workflow management. Now, with the emergence of new technologies such as web service, grid, this problem has become more complicated in service-...
We consider simple digital curves in a 3D orthogonal grid as special polyhedrally bounded sets. These digital curves model digitized curves or arcs in three-dimensional euclidean ...
We investigate the relationship between two kinds of vertex colorings of graphs: uniquemaximum colorings and conflict-free colorings. In a unique-maximum coloring, the colors are ...
We discuss design issues related to the transformation of a mature Agent-Based Model (ABM) for computational epidemiology into a “grid-aware” version. EpiSims is a distributed...
In this paper we argue that it is possible to couple the advantages of programming with the well-known abstraction of RPC with asynchronous programming models adequate for wide-ar...
