RFID collision is a main challenge imposed by radio wave links shared among a reader and many tags in interrogation zone. Collision is a power-consuming event that reduces the performance of RFID systems. Low power consumption strategy would ensure longer operational life of tags and reader by battery-powered supply. Application of several anti-collision algorithms makes it possible for reader to...
This paper proposes to study a novel problem, discovering a Smallest Unique Subgraph (SUS) for any node of interest specified by user in a heterogeneous social network. The rationale of the SUS problem lies in how a person is different from any others in a social network, and how to represent the identity of a person using her surrounding relational structure in a social network.

Acoustic radar has the advantages of low cost, high resolution, and the simplicity for sampling and storage. Recent years, it has been widely studied and applied in fields such as target detection, recognition and imaging. However, the sound signal is usually wideband. The wideband correlation function is often used in active and passive detections. To address the problems of the errors and computational...
