Abstract— In this paper, we propose a distributed opportunistic access scheme for uplink OFDMA systems. The sub-carriers are grouped into several sub-channels. Users access these...
An early-life reliability model is presented that allows wafer test information to be used to predict not only the total number of burn-in failures that occur for a given product,...
We address the goal of making Delegation Logic (DL) into a practically implementable and tractable trustmanagement system. DL [22] is a logic-based knowledge representation (i.e.,...
A variety of hybrid genetic algorithms has been recently proposed to address the vehicle routing problem with time windows (VRPTW), a problem known to be NP-hard. However, very few...
An architecture is described for designing systems that acquire and manipulate large amounts of unsystematized, or so-called commonsense, knowledge. Its aim is to exploit to the fu...
