We study the problem of querying data sources that accept only a limited set of queries, such as sources accessible by Web services which can implement very large (potentially inf...
We consider the problem of obtaining “nice” quadrangulations of planar sets of points. For many applications “nice” means that the quadrilaterals obtained are convex if po...
— A directional sensor network consists of a number of directional sensors, which can switch to several directions to extend their sensing ability to cover the interested targets...
Abstract. Within Self-reconfiguring systems two basic problems arise: on instruction level, reconfigurable instruction sets make program generation and execution inherently difficu...
