RFIDs are an interesting approach to accessing anything through the network. The most commonly mentioned variant is the passive RFID, but it has several serious problems. This paper focuses on the "active" RFID to realize "ubiquitous communication". First, the principle of active tags is mentioned, and the problem of readout rate is considered. Several(More)
Two packing algorithms for traffic-engineered label-switched paths (TE-LSP) are proposed in order to efficiently accommodate point-to-point (P2P) and point-to-multipoint (P2MP) TE-LSPs in a multi-protocol label switching (MPLS) network. Computer simulation results show that these algorithms calculate more efficient routes and accommodate more LSPs than a(More)
Duodenal ulcer beyond the bulb occurred in a diabetic patient when he was in ketoacidotic coma causing serious anemia. Early investigation of the stomach and duodenum by endoscope was quite valuable for evaluating this bleeding complication and the healing process of the lesion was serially recorded. Since several cases of diabetic coma have been reported(More)
Most applications executed on massively parallel computer systems, such as large-scale simulations for uid analysis and image recognition, require large storage space and high processing speed to process the vast amount of data. In order to process and store the large quantity of data e ectively, the secondary storage of massively parallel computer systems(More)
