  1. 21. Decentralized Resource Sharing and Associationin in Wireless Networks

    Författare :Yuzhe Xu; Carlo Fischione; Sinem Coleri Ergen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In wireless networks, some of the most important supporting functionalities are decentralized resource sharing and association of clients to access points. These functionalities aim to optimally allocate the available wireless transmission resources, for example, time or spectrum channels, the transmit power, access points, and relaying opportunities, all of which are subject to availability constraints.

  3. 22. Design of Reliable Communication Solutions for Wireless Sensor Networks : Managing Interference in Unlicensed Bands

    Författare :Luca Stabellini; Jens Zander; Andreas Kassler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : Recent surveys conducted in the context of industrial automation have outlined that reliability concerns represent today one of the major barriers to the diffusion of wireless communications for sensing and control applications: this limits the potential of wireless sensor networks and slows down the adoption of this new technology. Overcoming these limitations requires that awareness on the causes of unreliability and on the possible solutions to this problem is created. LÄS MER

  4. 23. Learning from Multiple Domains

    Författare :Zahra Taghiyarrenani; Sławomir Nowaczyk; Sepideh Pashami; Mohamed-Rafik Bouguelia; Ali Etemad; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Domain adaptation (DA) transfers knowledge between domains by adapting them. The most well-known DA scenario in the literature is adapting two domains of source and target using the available labeled source samples to construct a model generalizable to the target domain.

    Sammanfattning :  The explosive proliferation of mobile users and wireless data traffic in recent years pose imminent challenges upon wireless system design. The trendfor wireless communications becoming more complicated, decentralized andintelligent is inevitable. LÄS MER

  7. 25. Informatisk forskning om riskanalysprocess applicerad på Apoteket AB:s kundcenterverksamhet

    Författare :Patrik Brandt; Louise Wennberg; Louise Östlund; Blekinge University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Riskanalys; Apoteket AB; Kundcenterverksamhet; Informationssäkerhet; Informatik; Computer Science;

    Sammanfattning : English summary This licentiate paper describes a study of how the introduction of Customer Care Centres into The Corporation of Swedish Pharmacies affects its work on risk analysis. The two Customer Care Centres in operation today function as central nodes to which calls are connected that before were usually answered by one of the country’s 900 pharmacies. LÄS MER
