    CONTREX: Design of embedded mixed-criticality CONTRol systems under consideration of EXtra-functional properties

    Get PDF
    The increasing processing power of today’s HW/SW platforms leads to the integration of more and more functions in a single device. Additional design challenges arise when these functions share computing resources and belong to different criticality levels. CONTREX complements current activities in the area of predictable computing platforms and segregation mechanisms with techniques to consider the extra-functional properties, i.e., timing constraints, power, and temperature. CONTREX enables energy efficient and cost aware design through analysis and optimization of these properties with regard to application demands at different criticality levels. This article presents an overview of the CONTREX European project, its main innovative technology (extension of a model based design approach, functional and extra-functional analysis with executable models and run-time management) and the final results of three industrial use-cases from different domain (avionics, automotive and telecommunication).The work leading to these results has received funding from the European Community’s Seventh Framework Programme FP7/2007-2011 under grant agreement no. 611146

    CHORUS Deliverable 3.3: Vision Document - Intermediate version

    Get PDF
    The goal of the CHORUS vision document is to create a high level vision on audio-visual search engines in order to give guidance to the future R&D work in this area (in line with the mandate of CHORUS as a Coordination Action). This current intermediate draft of the CHORUS vision document (D3.3) is based on the previous CHORUS vision documents D3.1 to D3.2 and on the results of the six CHORUS Think-Tank meetings held in March, September and November 2007 as well as in April, July and October 2008, and on the feedback from other CHORUS events. The outcome of the six Think-Thank meetings will not just be to the benefit of the participants which are stakeholders and experts from academia and industry – CHORUS, as a coordination action of the EC, will feed back the findings (see Summary) to the projects under its purview and, via its website, to the whole community working in the domain of AV content search. A few subjections of this deliverable are to be completed after the eights (and presumably last) Think-Tank meeting in spring 2009

    Dynamic Approach to Competitive Intelligence: Case Studies of Large-Scale Swiss Telecom Firms

    Get PDF
    The research aim is to understand how the competitive intelligence (CI) process in large-scale Swiss telecom companies contributes to management decision-making. Studying CI activities of the Swiss large-scale telecom firms (Swisscom, Sunrise, Orange/Salt, Cablecom) in a dynamic European context offers useful insight into the critical challenges that service firms now face when developing intelligence in disruptive market contexts where aggressive competitive behaviour is evident. In considering CI theory, this study has reviewed perspectives drawn from research on the CI process, studies on knowledge management and work on systems thinking. In extending the predominant modular view of CI to include elements of systems thinking, this study has added to our academic understanding of CI at firm level. An Integrative CI Activities framework was developed that enables a more holistic perspective of CI to be adopted, taking account of operational, organisational and strategic perspectives. A diagram representing the range of CI analysis methodologies has also been generated, that differentiates between internal/external orientation and static/dynamic forms of CI analysis. Such frameworks can be used by CI researchers in other market contexts. The methodology for this study drew on a pragmatist philosophy, using a case study strategy that adopted mixed methods in data collection, including semi-structured depth interviews with top CI Analysts in each firm. Findings have shown differences in the scope of CI Activities that link to stages of CI development (developing, developed) and variation between headquarters-centred and firm-centred approaches to CI planning and implementation. The adoption of query based, flexible analysis approaches in firm-centred settings differ from more structured CI analysis techniques in headquarters-based firms. Evidence from this study suggests that networked communication, strong feedback mechanisms and the adoption of more flexible CI analyst roles link to more effective CI processes and to greater potential for direct CI contribution to decision-making. Key contributions emerge through the three lenses of analysis adopted (operational, organisational and strategic); in terms of operational CI processes, the study identifies a complex integrated system at work in firms that implement CI effectively. In studying the link between organisational structure and CI analysis, the study has mapped organisational support patterns and how they shape the CI process at firm level. With respect to the strategic lens, following a detailed worked study of predictive analysis in one case firm, findings have identified adaptiveness in CI design as essential to address disruptive market change. Managerial consideration include a need for a) greater flexibility in CI implementation at firm level to adapt to turbulent markets, b) acknowledgement of the importance of the CI analyst role further and c) more dynamic CI content to be generated by CI analysts

    AI-native Interconnect Framework for Integration of Large Language Model Technologies in 6G Systems

    Full text link
    The evolution towards 6G architecture promises a transformative shift in communication networks, with artificial intelligence (AI) playing a pivotal role. This paper delves deep into the seamless integration of Large Language Models (LLMs) and Generalized Pretrained Transformers (GPT) within 6G systems. Their ability to grasp intent, strategize, and execute intricate commands will be pivotal in redefining network functionalities and interactions. Central to this is the AI Interconnect framework, intricately woven to facilitate AI-centric operations within the network. Building on the continuously evolving current state-of-the-art, we present a new architectural perspective for the upcoming generation of mobile networks. Here, LLMs and GPTs will collaboratively take center stage alongside traditional pre-generative AI and machine learning (ML) algorithms. This union promises a novel confluence of the old and new, melding tried-and-tested methods with transformative AI technologies. Along with providing a conceptual overview of this evolution, we delve into the nuances of practical applications arising from such an integration. Through this paper, we envisage a symbiotic integration where AI becomes the cornerstone of the next-generation communication paradigm, offering insights into the structural and functional facets of an AI-native 6G network

    A SLR on Customer Dropout Prediction

    Get PDF
    Dropout prediction is a problem that is being addressed with machine learning algorithms; thus, appropriate approaches to address the dropout rate are needed. The selection of an algorithm to predict the dropout rate is only one problem to be addressed. Other aspects should also be considered, such as which features should be selected and how to measure accuracy while considering whether the features are appropriate according to the business context in which they are employed. To solve these questions, the goal of this paper is to develop a systematic literature review to evaluate the development of existing studies and to predict the dropout rate in contractual settings using machine learning to identify current trends and research opportunities. The results of this study identify trends in the use of machine learning algorithms in different business areas and in the adoption of machine learning algorithms, including which metrics are being adopted and what features are being applied. Finally, some research opportunities and gaps that could be explored in future research are presented.info:eu-repo/semantics/publishedVersio
