Due to the well-developed technology and its variety of applications, the Radio Frequency Identifications (RFIDs) become more and more popular. In many applications such as authentication, the RFID systems need security mechanism to resist all possible attacks and threats. However, most of the security mechanisms always too complex on computation or need(More)
Due to the well-developed technology, the radio frequency identification (RFID) is widely used in all areas. For some applications, the RFID system simply worked as a memory card without security mechanism. However, in many applications, the RFID systems need security mechanism for authentication. In scenario such as e-passport, the RFID systems even need(More)
The cancer classification through gene expression patterns becomes one of the most promising applications of the microarray technology. It is also a significant procedure in bioinformatics. In this study a grid computing based evolutionary mining approach is proposed as discriminant function for gene selection and tumor classification. The proposed approach(More)
Topics on reverse logistics have been discussed over the years. Most of them are dealt with by assuming that facilities are kept open once they are established, and no inventory is stocked at intermediate recycling stations. By simultaneously relaxing these two assumptions, this paper studies a reverse logistics system with multiple items of which each(More)
