We give algorithms to find the optimal disjoint paths around a rectangle. The set of disjoint paths connects a set of sources to a set of sinks (no fixed pairing between the sour...
Motivated by the increasing popularity of OFDMA, this paper studies the sum-rate optimality of OFDMA as an uplink multicarrier multiple-access scheme. We address the relationship ...
Relational query optimizers have traditionally relied upon table cardinalities when estimating the cost of the query plans they consider. While this approach has been and continue...
Abstract. Reactive systems are often modelled as two person antagonistic games where one player represents the system while his adversary represents the environment. Undoubtedly, t...
DarGridⅡ is an implemented database gird system whose goal is to provide a semantic solution for integrating database resources on the web. Although many algorithms have been pro...
