  1. 11. Survivability control using data-driven approaches and reliability analysis for wave energy converters

    Författare :Zahra Shahroozi; Jens Engström; Malin Göteman; Lars Johanning; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power maximization; prediction horizon; extreme wave conditions; wave tank experiment; numerical WEC-Sim analysis; reliability analysis; statistical methods; environmental design load; fatigue analysis; statistical methods; survivability analysis; neural network methods;

    Sammanfattning : Wave energy, with five times the energy density of wind and ten times the power density of solar, offers a compelling carbon-free electricity solution. Despite its advantages, ongoing debates surround the reliability and economic feasibility of wave energy converters (WECs). LÄS MER

  3. 12. Platform Design : Creating Meaningful Toolboxes When People Meet

    Författare :David Joaquin Cuartielles Ruiz; Teemu Leinonen; Malmö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; Platform Design; Interaction Design;

    Sammanfattning : Platform Design is a study of different viewpoints on the creation of digital systems, and how they converge in platforms designed, built, and managed by communities. As sociotechnical constructs in which features emerge through the interaction of different stakeholders, platforms are understood as both means and outcomes—the ‘things’ or boundary objects in a design process—generating the spaces where communities of practice can form.

  4. 13. Behovet av struktur och frihet : En avhandling om situationsanpassad facilitering vid samarbetsinriktad modellering

    Författare :Anders Hjalmarsson; Göran Goldkuhl; Stefan Cronholm; Mikael Lind; Anne Persson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Collaboration; modeling; facilitation and situational adjustment; Samarbete; modellering; facilitering och situationsanpassning; Information technology; Informationsteknik;

    Sammanfattning : Informationssystem är resultatet av samarbete människor emellan. System designas, realiseras, testas och implementeras i de verksamheter som de ska stödja. Samarbete krävs under alla dessa steg. LÄS MER

  5. 14. On MIMO Systems and Adaptive Arrays for Wireless Communication : Analysis and Practical Aspects

    Författare :Mattias Wennström; Michael A. Jensen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; antenna array; calibration; MIMO system; flat fading; non-linear amplifier; switched parasitic antenna; analog beamformer; adaptive antenna testbed; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

    Sammanfattning : This thesis is concerned with the use of multiple antenna elements in wireless communication over frequency non-selective radio channels. Both measurement results and theoretical analysis are presented. New transmit strategies are derived and compared to existing transmit strategies, such as beamforming and space-time block coding (STBC). LÄS MER

  7. 15. Managing information security for mobile devices in small and medium-sized enterprises : Information management, Information security management, mobile device

    Författare :Martin Brodin; Jeremy Rose; Rose-Mharie Åhlfeldt; Stewart Kowalski; Miko Siponen; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information management; Information security management; mobile device; Information Systems; Informationssystem IS ;

    Sammanfattning : The rapid proliferation of mobile devices makes mobile security a weak point in many organisations’ security management. Though there are a number of frameworks and methods available for improving security management, few of these target mobile devices, and most are designed for large organisations. LÄS MER
