  1. 1. Simulation of runaway electron generation during plasma shutdown by impurity injection

    Författare :Tamás Fehér; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; disruption mitigation; fusion plasma physics; impurity injection; runaway electron; tokamak;

    Sammanfattning : Disruptions are dangerous instabilities in tokamaks that should be avoided or mitigated. One possible disruption mitigation method is to inject impurities into the plasma to shut it down in a controlled way. Runaway Electrons (REs) can be generated after the plasma is cooled down bythe impurities and these electrons can damage the tokamak. LÄS MER

  2. 2. Supply Chain Risk Management : Identification, Evaluation and Mitigation Techniques

    Författare :S.Nurmaya Musa; Ou Tang; Jan Olhager; David Zhang; Linköpings universitet; []
    Nyckelord :Supply chain risk management; risk analysis; risk control; co-citation; system dynamics; modelling;

    Sammanfattning : Supply chains have expanded rapidly over the decades, with the aim to increase productivity, lower costs and fulfil demands in emerging markets. The increasing complexity in a supply chain hinders visibility and consequently reduces one’s control over the process. LÄS MER

  3. 3. Modeling cost-effective climate change mitigation strategies

    Författare :Fredrik Hedenus; Chalmers University of Technology; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The challenge of reducing anthropogenic emissions of greenhouse gases calls for a wide variety of analyses to make the mitigation effort efficient and achievable. This thesis explores five different issues related to carbon abatement. LÄS MER

  4. 4. Decision support for sustainable water security

    Författare :Karin Sjöstrand; Dale Whittington; RISE; []
    Nyckelord :;

    Sammanfattning : Society’s large dependence on water, in combination with climate, socio-economic and demographic changes, places a massive pressure on our freshwater resources. As a result, water crisis, defined as a significant decline in the available quality and quantity of freshwater, is now considered to be among the most critical global risks to society. LÄS MER

  5. 5. Decision support for sustainable water security

    Författare :Karin Sjöstrand; Chalmers University of Technology; []
    Nyckelord :decision support; water scarcity; water availability; water security; drinking water supply; multi-criteria decision analysis; sustainability; cost-benefit analysis; marginal abatement cost curves; risk assessment;
