Abstract. We present a method for mapping security levels among the components of a distributed system where data in the local sources are represented in XML. Distributed data is i...
Let S be a set of n points in a metric space, and k a positive integer. Algorithms are given that construct k-fault-tolerant spanners for S. If in such a spanner at most k vertice...
