  2. 1. The Quest for Edge Awareness, Lessons not yet learned : PhD Thesis on practical and situated usefulness of advanced technological systems among inescapable uncertainties and competing interests in a world of dynamic changes

    Author : Patrik Stensson; Anders Jansson; Pär Ågerfalk; Martin Norsell; Erik Hollnagel; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; critical realism; human factors; situation awareness; resilience engineering; human-machine interaction; automation; autonomy; situated usefulness; systems thinking; sociotechnical systems; edge awareness; Människa-dator interaktion; Human-Computer Interaction;

    Abstract : This thesis problematizes the concept of usefulness, in part by taking questions to the extreme. The starting point is the contemporary view of usefulness, a view that remains within a traditional paradigm of technical rationality in which important aspects are disregarded or not perceived because they are not part of the equation.

  4. 2. Power Grid Resilience to High Impact Low Probability Events

    Author : Samuel Forsberg; Mikael Bergkvist; Karin Thomas; Lars Nordström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extreme weather; HILP events; offshore wind; power grid; resilience; vulnerability; Electrical Engineering with specialization in Systems Analysis; Elektroteknik med inriktning mot systemanalys;

    Abstract : The electrification of societies and the decarbonisation of electricity production are changing energy systems worldwide. A fast transition towards the replacement of fossil fuels by intermittent renewable energy sources is expected in the next decades to combat climate change. READ MORE

    Author : Mahmoud Zaher; Emil Björnson; Marina Petrova; Mikael Sternad; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cell-free massive MIMO; power allocation; sum-SE maximization; proportional fairness; spectral efficiency; deep learning; handover; cluster formation; pilot assignment; unknown interference; outage; multiuser MIMO.; Cellfri massiv MIMO; effektreglering; summa-SE-maximering; proportionell rättvisa; spektraleffektivitet; djupinlärning; överlämning; klusterbildning; pilottilldelning; okända störningar; avbrottsnivå; MIMO för flera användare.; Datalogi; Computer Science;

    Abstract : The ever-growing demand of wireless traffic poses a challenge for current cellular networks. Each new generation must find new ways to boost the network capacity and spectral efficiency (SE) per device. A pillar of 5G is massive multiple-input-multiple-output (MIMO) technology. READ MORE

  6. 4. Impact of climate change on integrated resource systems- Insights from selected East African case studies

    Author : Vignesh Sridharan; Mark I. Howells; William Usher; Sonia Yeh; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; climate change; integrated assessment; Uganda; agriculture; water and energy systems; climate resilience; CLEW nexus; Energy Technology; Energiteknik;

    Abstract : With countries revisiting their climate pledges agreed at the conference of parties (COP) in Paris, in 2015, the discussion on the impact of changes in the long-term climate on natural resources has never been more relevant. Specifically, since the 2011 Bonn conference on the nexus between resource systems, the interlinkages between energy, water and land resource systems and their climatic connections are on the radar.

  7. 5. Technical infrastructure networks as socio-technical systems : Addressing infrastructure resilience and societal outage consequences

    Author : Finn Landegren; Industriell elektroteknik och automation; []
    Keywords : Critical infrastructure; Socio-technical system; Resilience; Restoration; Simulation; Quality of supply regulation; Societal consequence;

    Abstract : Research area: Modern society is increasingly dependent on a range of technical infrastructure networks including e.g. power, transport and IT networks. This dependence is illustrated by large disturbances which from time to time affect these systems, often to an extent which few did consider possible. READ MORE
