    A new MDA-SOA based framework for intercloud interoperability

    Cloud computing has been one of the most important topics in Information Technology which aims to assure scalable and reliable on-demand services over the Internet. The expansion of the application scope of cloud services would require cooperation between clouds from different providers that have heterogeneous functionalities. This collaboration between different cloud vendors can provide better Quality of Services (QoS) at the lower price. However, current cloud systems have been developed without concerns of seamless cloud interconnection, and actually they do not support intercloud interoperability to enable collaboration between cloud service providers. Hence, the PhD work is motivated to address interoperability issue between cloud providers as a challenging research objective. This thesis proposes a new framework which supports inter-cloud interoperability in a heterogeneous computing resource cloud environment with the goal of dispatching the workload to the most effective clouds available at runtime. Analysing different methodologies that have been applied to resolve various problem scenarios related to interoperability lead us to exploit Model Driven Architecture (MDA) and Service Oriented Architecture (SOA) methods as appropriate approaches for our inter-cloud framework. Moreover, since distributing the operations in a cloud-based environment is a nondeterministic polynomial time (NP-complete) problem, a Genetic Algorithm (GA) based job scheduler proposed as a part of interoperability framework, offering workload migration with the best performance at the least cost. A new Agent Based Simulation (ABS) approach is proposed to model the inter-cloud environment with three types of agents: Cloud Subscriber agent, Cloud Provider agent, and Job agent. The ABS model is proposed to evaluate the proposed framework.Fundação para a Ciência e a Tecnologia (FCT) - (Referencia da bolsa: SFRH SFRH / BD / 33965 / 2009) and EC 7th Framework Programme under grant agreement n° FITMAN 604674 (http://www.fitman-fi.eu

    The Employment Training Panel, Annual Report September 30, 1984

    The Employment Training Panel is helping California, its businesses and workers implement new technologies and foster mature industries to keep California on the cutting edge of competition and enterprise. Since it was created January 1, 1983, the Employment Training Panel has committed $69.6 million to retrain 20,955 workers for jobs that more than 1,500 California employers need done so that the state\u27s economy can continue to grow and prosper. This report describes the Panel\u27s first 18 months of operation

    Past and Present Energy Societies: How Energy Connects Politics, Technologies and Cultures

    Get PDF
    Abundant, salutary, problematic - energy makes history. As a symbol, resource and consumer good, it shapes technologies, politics, societies and cultural world views. Focussing on a range of energy types, from electricity and oil to bioenergy, this volume analyzes the social, cultural and political concepts and discourses of energy and their implementation and materialization within technical systems, applications, media representations and consumer practice. By examining and connecting production, mediation and consumption aspects from an international and interdisciplinary perspective, the book offers an innovative view on how energy is imagined, discussed, staged and used

    The Anaesthesia Machine: Questioning a Design Evolution

    No full text
    An underlying fear for many in using new digital systems is not the 'digital' but the struggle to trust and see reality; this may represent the loss of an art or aesthetic judgement, over an empirical measurement.(1) Why do we have what we have - and what could we have? Since the acceptance of the "Boyle's" configuration as a design standard, the evolution of anaesthesia equipment has predominantly remained tethered to this design icon.(2) Increasingly governed by historical habits and industrial ideologies, significant gains in technology have denied anaesthetists ergonomic advantage, due in part, to a design stagnation of physical composition. In doing so, it has become a legend of origin and a convention of machine use, a situation that is traced back to the evolution of rag and bottle, portable inhaler, and the asymmetric layout of anaesthetic apparatus. One of the key difficulties or questions for design is how to implement new technologies to retain and strengthen the established product-person trust.(3) The past reveals two methods; first the traditional addition of technology to historical brands and established formats; and second, the innovative embodiment of task and technology in a search for better systems.(4) Within the evolution of the anaesthesia machine, design methodologies have colluded to satisfy safety, ignoring a profession's habits, resulting in a complex lamination of engineering (technology), interaction (ergonomics) and aesthetics (path dependence and manufactured style). The application of new digital technology demands a physical design response that can satisfy clinician needs, patient safety and the commercial goals of industry in balancing technology and safety to clinical outputs and user satisfaction.(5) The study presents an informative and investigative methodology to construct a proactive design base, cumulating in active involvement, an informed critical analysis and a prospective methodological vision. The concluding experiment focuses on information and ideals from anaesthetists, to firstly test the established composition; secondly to inform us of how anaesthetists envisage their equipment; and thirdly, how simulation and industrial design may partner in unlocking the transfer of creative knowledge. In applying this partnership as a strategic design confidant, a new understanding of design process and concomitant design within an elite profession is established. Altogether this thesis seeks to explore the anaesthesia machine, to investigate the past, create closer relationships with anaesthetists and act together prospectively towards questioning the established. It may be 'it is not a solution we are looking for but the right way (or process) to ask the questions’ to manifest a new answer.
