  1. 11. Beyond Massive MIMO : Trade-offs and Opportunities with Large Multi-Antenna Systems

    Författare :Juan Vidal Alegría; Kommunikationsteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO; massive MIMO; cell-free massive MIMO; Decentralized multi-antenna architectures; Decentralized schemes; WAX decomposition; LIS; Reconfigurable surfaces; RIS; IRS; ARIS; FRIS;

    Sammanfattning : After the commercial emergence of 5G, the research community is already putting its focus on proposing innovative solutions to enable the upcoming 6G. One important lesson put forth by 5G research was that scaling up the conventional multiple-input-multiple-output (MIMO) technology by increasing the number of antennas could be extremely beneficial for effectively multiplexing data streams in the spatial domain.

    Sammanfattning : Our society is increasingly beset by a range of interrelated crises - with the financial crisis, the energy crisis, and the global warming crisis as leading examples - forming a "meta-crisis" with its roots in processes deeply entrenched in society (Lane et al., 2011), and emanating from large-scale complex adaptive systems so strongly interlinked that they are hard to even define and delimit.

    Sammanfattning : This dissertation analyses how district heating systems in the Stockholm region have evolved and developed during the period 1978-2012. The thesis comprises four papers analyzing how district heating has been handled in municipal and regional planning. LÄS MER

  7. 15. VALUE CO-CREATION FOR SUSTAINABLE PRODUCT SERVICE SYSTEM DESIGN : OPPORTUNITY FOR GLOBAL MANUFACTURING COMPANIES

    Författare :Yan Zhang; Tobias Larsson; Andreas Larsson; Kent R Johansson; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Product-Service System; Manufacturing company; Innovation Framework; PSS design; Value Co-creation; Case study; Maskinteknik; Mechanical Engineering; Maskinteknik; Mechanical Engineering;

    Sammanfattning : There is a gradually spreading servitization trend that is forcing industrial manufacturing companies acting in the global market to rethink their business. Manufacturing companies that were traditionally perceived as product-centered, are today increasingly influenced by a service-oriented theory, which claims that manufacturing companies are driven to shift their business focus towards a strategy where customer-perceived value is in the spotlight, and where products are bundled with services to offer Product-Service Systems (PSS).
