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

    Författare :Tamás Fehér; [2011]
    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

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :S.Nurmaya Musa; Ou Tang; Jan Olhager; David Zhang; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Fredrik Hedenus; [2008]

    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. Wireline Communications in a Wireless World

    Detta är en avhandling från Lund University

    Författare :Yezi Huang; [2017-11-03]

    Sammanfattning : The whole society is digitalizing, filled with streaming services, cloud computing and an ambition of ubiquitous connectivity. To address the data demand, ultra-fast broadband, at the speeds of 1Gbps and more, is developed and deployed. Optical fibers have been long viewed as a future-proof carrier for the ultra-fast broadband. LÄS MER

  5. 5. Tearing mode dynamics in the presence of resonant magnetic perturbations

    Detta är en avhandling från Stockholm : Universitetsservice US AB

    Författare :Richard Fridström; Per Brunsell; Marco Cecconello; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tearing mode; plasma; fusion; reversed-field pinch; RFP; magnetic; confinement; resonant; perturbation; magnetohydrodynamics; MHD; EXTRAP T2R; Madison Symmetic Torus; Physics; Fysik;

    Sammanfattning : Magnetically confined fusion (MCF) plasmas are typically subject to several unstable modes. The growth of one mode can limit the plasma energy confinement and might cause a termination of the plasma. Externally applied resonant magnetic perturbations (RMPs) are used to control and to mitigate some of the unstable modes. LÄS MER
