| Abstract | Benefitting from advanced web technologies like JavaScript, CSS3 and HTML5, current web applications can provide ever richer functionalities and user experiences, on both PC and mobile devices like tablet computers and smartphones. Furthermore, they can perform complex computations which are usually resource-intensive and consuming, e.g., data analytic application and augmented reality games. Mobile devices might suffer from their limited computing capabilities and resources. As mobile devices now are gaining access through excellent connectivity with much more powerful cloud-side services, and offloading can be a potential solution. This paper presents the design and implementation of the AppMobiCloud system for improving mobile web applications by leveraging the mobile-cloud convergence. At development time, AppMobiCloud employs a combination of profiling and points-to analysis. This facilitates application developers to find the computation-intensive code fragments, and specifies whether they can be offloaded with some constraints. At runtime, AppMobiCloud migrates the chosen JavaScript code fragments from the mobile devices for remote execution. It synchronizes client-side application runtime context and constructs the "cloned" context at server, executing the codes there and re-integrating the result back to the mobile device. We evaluate our approach on three well-known JavaScript benchmarks, Dromaeo, V8 and Kraken, and a typical computation-intensive AI game. The evaluation demonstrates that our work can reduce JavaScript application's execution time and energy consumption respectively on mobile devices up to 98% and 83%. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
