Abstract: Fuzzy association rule mining (Fuzzy ARM) uses fuzzy logic to generate interesting association rules. These association relationships can help in decision making for the solution of a given problem. Fuzzy ARM is a variant of classical association rule mining. Classical association rule mining uses the concept of crisp sets. Because of this reason classical association rule mining has several drawbacks. To overcome those drawbacks the concept of fuzzy association rule mining came. Today there is a huge number of different types of fuzzy association rule mining algorithms are present in research works and day by day these algorithms are getting better. But as the problem domain is also becoming more complex in nature, continuous research work is still going on. In this paper, we have studied several well-known methodologies and algorithms for fuzzy association rule mining. Four important methodologies are briefly discussed in this paper which will show the recent trends and future scope of research in the field of fuzzy association rule mining.

Abstract: The diverse and dynamic nature of elements and techniques used to develop Web Application, due to the lack of testing technique and effective programming principles which are used for implementing basic software engineering principles, and undisciplined development processes insure by the high pressure of a very short time to satisfy market request to develop Web application. This paper represent approaches of reengineering in web that how reengineering process can be carried out to evolution activities in legacy system as well we propose the V-model for re-engineering process. This paper presents the need of the technologies and approaches for building new web-services from existing web-applications. In this paper we present the processing of V-model for Reengineering in web application which is the extension of V-model used in software domain. In our approach V-model incorporates with the methodology throughout the phases of web development process to re-engineer the web system.

Abstract: Vehicle-to-Infrastructure (V2I) Communications for Safety is the wireless exchange of critical safety and operational data between vehicles and roadway infrastructure, intended primarily to avoid motor vehicle crashes. Vehicle-to-infrastructure (V2I) communication based on wireless local area network (WLAN) IEEE 802.11 standard technology can support user in-motion to achieve preferable Internet connectivity. This standard is created for urgent short message transmission.The IEEE 802.11 standard defines an infracture mode with at least one central access point connected to a wired network. In this paper we present an experimental study of IEEE802.11g using off-the-shelf devices in vehicle-to-infrastructure small scale scenario. In order to evaluate the V2I the type of communication in large scale scenario and intelligent transportation systems (ITS) will necessitate wireless vehicle-to-infrastructure (V2I) communica-tions. This wireless link can be implemented by several technolo-gies, such as digital broadcasting, cellular communication, or dedicated short range communication (DSRC) systems. Analyses of the coverage and capacity requirements are presented when each of the three systems are used to implement the V2I link.
