Every Cloud Has a Push Data Lining: Incorporating Cloud Services in a Context-Aware Application

We investigated context-awareness by utilising multiple sources of context in a mobile device setting. In our experiment we developed a system consisting of a mobile client, running on the Android platform, integrated with a cloud-based service. These components were integrated using pushmessaging technology.One of the key featureswas the automatic adaptation of smartphones in accordance with implicit user needs. The novelty of our approach consists in the use of multiple sources of context input to the system, which included the use of calendar data and web based user configuration tool, as well as that of an external, cloud-based, configuration file storing user interface preferences which, pushed at log-on time irrespective of access device, frees the user from having to manually configure its interface.The systemwas evaluated via two rounds of user evaluations (n = 50 users), the feedback of which was generally positive and demonstrated the viability of using cloud-based services to provide an enhanced context-aware user experience

WOLF: a Research Platform to Write NFC Secure Applications on Top of Multiple Secure Elements (With an Original SQL-Like Interface)

International audienceThis article presents the WOLF (Wallet Open Library Framework) platform which supports an original interface for NFC developers called " SE-QL ". SE-QL is a SQL-like interface which eases and optimizes NFC secure application development in making the heterogeneity of the Secure Element (SE) transparent. SE implementation could be " embedded " (eSE) in the mobile device, or inside the SIM Card (UICC), or " on-host " software-based, or in the Cloud (e.g. through HCE); every SE implementation has its own interface(s) making NFC secure-application development extremely cumbersome and complex. Proposed SE-QL solves this problem. This article demonstrates the feasibility and attractiveness of our approach based upon an original high-level API

Content adaptation for an adaptive hypermedia system

The aim of this paper is presenting the recommendation module of the Mathematics Collaborative Learning Platform (PCMAT). PCMAT is an Adaptive Educational Hypermedia System (AEHS), with a constructivist approach, which presents contents and activities adapted to the characteristics and learning style of students of mathematics in basic schools. The recommendation module is responsible for choosing different learning resources for the platform, based on the user's characteristics and performance. Since the main purpose of an adaptive system is to provide the user with content and interface adaptation, the recommendation module is integral to PCMAT’s adaptation model

Improving the adaptation of web applications to different versions of software with MDA

The Model-Driven Architecture (MDA) has been proposed as a way of separating the details of an implementation platform from the problem domain. This paper shows that this approach is also good for the adaptation of software to the different versions of the same platform. As an example, Spring Web Flow (SWF), a framework that allows the definition and representation of user interface flows in web applications, has been chosen. After six months of evolution, the web flows de¯ned with SWF 1.0 RC1 were not compatible with SWF 1.0. The paper analyzes the changes introduced by the new release, and it proposes an MDA-based approach to soften the impact of these changes

Development of a Web-based land evaluation system and its application to population carrying capacity assessment using .Net technology

The multi-disciplinary approach used in this study combines the state-of-the-art IT technology with an elaborated land evaluation methodology and results in a Web-based land evaluation system (WLES). The WLES is designed in such a way that the system operates both as a Web Application and as a Web Service. Implemented on top of the .NET platform, the WLES has a loosely coupled multi-layer structure which seamlessly integrates the domain knowledge of land evaluation and the soil database. The Web Service feature makes the WLES suitable to act as a building block of a larger system such as that of the population carrying capacity (PCC) assessment. As a reference application, a framework is made to assess the PCC on the basis of the production potential calculations which are available through the WLES Web Service interface
