One of the key problems that affect the data integrity of passive RFID systems is the collision among the tags. A popular anti-collision algorithm which dominates the standards in HF and UHF passive RFID systems is framed slotted Aloha(FSA) and some variations of FSA. Throughput of the RFID system which determines the performance/efficiency of the system is reduced rapidly when the number of tags inside the interrogation zone is increased. Using larger frame sizes is not always the solution. The best performance can be achieved when the slot number is equal to the tag number for FSA algorithm. In order to estimate the number of tags, a lot of work has been done. The existing algorithm about the tags estimation has been discussed in this paper. And an idle slot number based estimation algorithm is proposed. The idle slot number based estimation algorithm uses the idle slots in a frame. For performance analysis, the idle slot number based estimation algorithm was evaluated with the parameters of 128 slots to estimate the number of tags. The proposed method considers two situation, one is applied only 128 slots in a frame and all of them are used to estimate the number of tags;the other is applied the first 128 slots in a frame with 1024 slots frame. The results showed that the proposed algorithm can improve the efficiency of the number of RFID tag estimation and provide a reliable solution for cases with a high density of tags in the area.

This paper proposes a dynamic traffic management mechanism which addresses the problem of cost-optimal distribution of inevitable inter-domain traffic on multiple links, and enables dynamic overlay traffic management and adaptation to constantly changing traffic patterns to meet cost optimization goals. The mechanism allows for the management of traffic generated by overlay applications such as content delivery platforms, online storage systems, or P2P.

We, human beings, depend on other species on earth for our survival. Maintaining a sustainable and safe environment for all species including human beings is essential. Information Technologies and systems (ITSs) provide help as well as harm in this effort. Current and future generations of people must have knowledge about green environment and practice to achieve and maintain it. With this in mind the author has designed the course, "IT and Environment" as a general education course for IT, IS, CS as well as for all other students at Framingham State University during 2011. He has offered it during the summer of 2012 as an online course for the first time. This paper describes the course as it was designed and offered and the lessons learned from it.

In the present study, an amphiphilic chitosan-polylactide(CS-PLA) graft copolymer was synthesized through grafting polylactide(PLA) onto water-soluble chitosan(CS), and the chemical structure of this newly developed copolymer was confirmed by FT-IR, 1H NMR and thermogravimetric analysis(TGA). Stable flusilazole-loaded nanoparticles(NS), with a size near 280.3 nm and a loading content(LC) of 29.0%, were prepared for the fungicide delivery using a nanoprecipitation method. Moreover, size, size distribution and the flusilazole LC as well as the in vitro release profile of flusilazole-loaded NS were investigated. In conclusion, the NS could provide a controlled release of flusilazole and enhance the penetration of flusilazole in the plant compared with classical flusilazole emulsifiable concentrate(EC) formulation due to their small particle size. Therefore, the CS-PLA NS could be used as fungicide carriers for the flusilazole delivery system.

Now the supermarket is people's main shopping place, a wide variety of goods in the supermarket has brought great convenience to the public. But now as the supermarket and the number of customers increased, people looking for goods will waste a lot of time. It would cause the waste of time for people to shopping, also supermarkets will bring losses. RFID is a new automatic identification technology, which is mainly to achieve non-contact transmission of information using radio frequency signal, and to identify the purpose of the delivered information. Supermarket shoppers system based on RFID technology is combining electronic tag and the Internet of things, use electronic tag as a tool of product identification, and the use of the Internet of things to get product details and automatic generation of product information. This system uses the Sketchup to build three-dimensional model of supermarket, and use RFID technology, database technology to construct a supermarket guiding system. Products using RFID tags instead of bar codes has become an inevitable trend in the development of the flow of goods in the future, thus supermarket shopping guide system based on RFID technology has a very good prospects.
