Abstract: Cloud computing is Modern day's wonder. It is not a product but a service, which provides shared resources, software, and information to computers and other devices like smart phones as a utility over a network mainly internet[1]. Resources namely memory, storage space, processor, etc are not available at user's end explicitly. Service providers own these resources and user access them via the Internet. It comes with many advantages for business like lower operation cost, low capital investment, shorter startup time for new services, lower maintenance cost. Cloud computing is a boon for shifting computing from desktops to cloud. Now the new paradigm should be cloud computing for mobile users. The limitations for mobile cloud computing are limited availability of energy and wireless bandwidth. Mobile Cloud Computing combines cloud computing and mobile resources to overcome obstacles related to the performance (like battery life and bandwidth), environment (heterogeneity, scalability, and availability), and security (reliability, security and privacy). In this paper it is discussed how cloud computing may provide energy saving to mobile users and hence increasing the battery life of the mobile.

Abstract: There is a dramatic increase in academic publications and these publications are integrated to the digital libraries by making use of citation string. Any author can publish the journals conferences with the help of his own citation style. There is no specific format to the conferences and journals citation styles that are publishing on digital libraries. As there is no specific format to the citations it is difficult to any author or researchers when he want to perform field based searching on digital libraries. So it is an interesting problem to extract the components of citations string which is formatted in one of thousand different citation styles. The proposed citation parser named BibPro extracts components of citations strings more accurately with that of existing systems and achieves reasonable performance.

Keywords: Data integration, digital libraries, information extraction, sequence alignment.

Abstract: Understanding that the need for huge volume of data retrieved from the server requires a high performance system with versatile capability, the performance differs based on systems. Fundamentally there are many systems which will do the job of storing and retrieving the data from the server and one such system is Ajax. In this paper, we have worked on the server performance measures using AJAX mechanism. Though the performances of Ajax is low based on push and pull server functions, it has been overcome using state less push operation and pull operation. The result shown in this study provides a realistic approach for an efficient server mechanism.
