  • Cognitive Technology for Ultra-Wideband/WiMax Coexistence
    2007 2nd IEEE International Symposium on New Frontiers in Dynamic Spectrum Access Networks, 2007
    Co-Authors: Shridhar Mubaraq Mishra, Stephan Ten Brink, Ravi Mahadevappa, Robert W. Brodersen
    Abstract:

    Cognitive radios have been advanced as a Technology for the opportunistic use of under-utilized spectrum wherein secondary devices sense the presence of the primary user and use the spectrum only if it is deemed empty. The distinguishing aspect of Cognitive radios is the ability to sense the primary user and modify their transmission parameters to avoid interference to the primary. In this paper we explore the use of Cognitive Technology to enable the operation of ultra-wideband (UWB) devices in WiMax bands. In this particular example UWB devices must incorporate Cognitive Technology to detect and avoid (DAA) WiMax devices in certain regulatory domains. We start by discussing various options for detection and avoidance. We then describe the obstacles faced in achieving robust detection and avoidance with an on-chip implementation of basic DAA functionality. This implementation is based on the energy detector and can reliably detect WiMax uplink transmissions. Finally, we present empirical results for the operation of a single Cognitive Technology enabled UWB device with a WiMax system. This interaction also highlights the problem of dealing with listen before speak primaries where secondary transmission could interfere by denying the primary access to the medium.

  • Cognitive Technology for improving Ultra-Wideband (UWB) Coexistence
    2007 IEEE International Conference on Ultra-Wideband, 2007
    Co-Authors: Shridhar Mubaraq Mishra, Robert W. Brodersen
    Abstract:

    Cognitive radio Technology enables the opportunistic operation of secondary devices in frequency bands allocated to primary users. In this paper we explore how this Technology can enable ultra-wideband (UWB) systems to coexist with primary users. The distinguishing aspect of Cognitive radio Technology is the ability to detect and avoid primary users. We discuss two options for detecting the presence of primary devices - energy detection and preamble detection. The presence of multiple UWB devices can aid detection by enabling cooperative sensing of the primary. We analyze various techniques for cooperative sensing which differ in the amount of information they need to exchange between radios and the regime in which they are potentially advantageous. Furthermore, the wideband aspect of UWB offers many challenges to detection but also facilitates the detection process in several ways. These distinguishing aspects of wideband detection are also highlighted in this paper.

  • Cognitive dimensions of notations design tools for Cognitive Technology
    Lecture Notes in Computer Science, 2001
    Co-Authors: Alan F. Blackwell, Carol Britton, Thomas R. G. Green, Corin A. Gurr, Gada Kadoda, Maria Kutar, Martin J. Loomes, Chrystopher L. Nehaniv, Marian Petre, Chris Roast
    Abstract:

    The Cognitive Dimensions of Notations framework has been created to assist the designers of notational systems and information artifacts to evaluate their designs with respect to the impact that they will have on the users of those designs. The framework emphasizes the design choices available to such designers, including characterization of the user's activity, and the inevitable tradeoffs that will occur between potential design options. The resuliing framework has been under development for over 10 years, and now has an active community of researchers devoted to it. This paper first introduces Cognitive Dimensions. It then summarizes the current activity, especially the results of a one-day workshop devoted to Cognitive Dimensions in December 2000, and reviews the ways in which it applies to the field of Cognitive Technology.

  • The Cognitive Technology Revolution: A New Role of HR Practices?
    Digital HR, 2018
    Co-Authors: Amelia Manuti, P De Palma, Pasquale Davide Palma
    Abstract:

    This chapter aims to discuss the negative and positive aspects connected to the cultural turn toward the Cognitive intelligence era in organizations. The opportunities granted by Technology-based people management practices (e.g. Watson, big data, etc.) are critically analysed in the attempt to redefine the role of human resource management as an organizational strategic asset. The authors see positively the affordances granted by Technology as long as HRM practices would succeed in integrating them within the organizational vision. An concrete example is given by organizational network analysis, that might support organizations in investigating informal network and in planning adequate HRM practices.

  • The Cognitive Technology Revolution: A New Identity for Workers
    Digital HR, 2017
    Co-Authors: Amelia Manuti, Pasquale Davide Palma
    Abstract:

    Framing the socio-cultural and economical revolution brought about by Cognitive technologies, the chapter aims to discuss the redefinition of workers’ identity and the meaning they attach to work. Yet, authoritative studies in the field show that work experience represents a symbolic space for the development of personal and social identity. The emergence of new Technology-based working modalities has concretely redesigned the role played by people at work. Moreoever, this change is also framed within the discussion about an unavoidable clash between different generations of workers (namely baby boomers, gen x and millenials) who are animated by different values, different expectations and technological skills. Therefore, the chapter discusses challenges and potentialities associated with this revolution, highlighting how the questions posed by technologies will also impose a redefinition of HRM practices.
