    Composition and Self-Adaptation of Service-Based Systems with Feature Models

    The adoption of mechanisms for reusing software in pervasive systems has not yet become standard practice. This is because the use of pre-existing software requires the selection, composition and adaptation of prefabricated software parts, as well as the management of some complex problems such as guaranteeing high levels of efficiency and safety in critical domains. In addition to the wide variety of services, pervasive systems are composed of many networked heterogeneous devices with embedded software. In this work, we promote the safe reuse of services in service-based systems using two complementary technologies, Service-Oriented Architecture and Software Product Lines. In order to do this, we extend both the service discovery and composition processes defined in the DAMASCo framework, which currently does not deal with the service variability that constitutes pervasive systems. We use feature models to represent the variability and to self-adapt the services during the composition in a safe way taking context changes into consideration. We illustrate our proposal with a case study related to the driving domain of an Intelligent Transportation System, handling the context information of the environment.Work partially supported by the projects TIN2008-05932, TIN2008-01942, TIN2012-35669, TIN2012-34840 and CSD2007-0004 funded by Spanish Ministry of Economy and Competitiveness and FEDER; P09-TIC-05231 and P11-TIC-7659 funded by Andalusian Government; and FP7-317731 funded by EU.

    Social Mental Shaping: Modelling the Impact of Sociality on Autonomous Agents' Mental States

    No full text
    This paper presents a framework that captures how the social nature of agents that are situated in a multi-agent environment impacts upon their individual mental states. Roles and relationships provide an abstraction upon which we develop the notion of social mental shaping. This allows us to extend the standard Belief-Desire-Intention model to account for how common social phenomena (e.g. cooperation, collaborative problem-solving and negotiation) can be integrated into a unified theoretical perspective that reflects a fully explicated model of the autonomous agent's mental state

    A pedagogy for work-based learning at level 5 for foundation degree studies in architectural technology and construction management

    The central Government agenda towards widening participation in Higher Education and its target of 50 % of adults to be involved by 2010 is amongst the drivers towards innovative and changing modes of learning and teaching. A by product of this is the number of students adopting a part-time route toward academic qualification. The ramifications of this involve limited time for personal attendance at teaching institutions and a requirement for directed learning within the framework of the workplace. The interpretation both nationally and internationally of work based learning appears to be inconsistent. The research involved in this paper concludes with a recommendation to identify that model appropriate for students studying toward the awards of Foundation Degree in Architectural Technology and Construction Management at Northumbria University
