  2. 1. Remote sensing of supra-glacial lakes on the west Greenland Ice Sheet

    Author : A. Malin Johansson; Ian A. Brown; Peter Jansson; Johan Kleman; Andreas Ahlstrøm; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supra-glacial lakes; Greenland Ice Sheet; Ice melting; Remote sensing; SAR; MODIS; Time-series analysis; Physical Geography; naturgeografi;

    Abstract : The Greenland Ice Sheet is the largest ice sheet in the northern hemisphere. Ongoing melting of the ice sheet, resulting in increased mass loss relative to the longer term trend, has raised concerns about the stability of the ice sheet. Melt water generated at the surface is temporarily stored in supra-glacial lakes on the ice sheet. READ MORE

  5. 3. Balancing the flow of wood and use of machinery in harvesting operations : new perspectives on how to improve performance in the wood supply chain

    Author : Malin Johansson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Meeting current wood supply objectives requires a certain flexibility in the wood procurement system. Suitable buffers to generate flexibility include creating a balance between flow and resource efficiency. Research on resource efficiency (e.g. READ MORE

  6. 4. International manufacturing relocation - the phenomenon of backshoring

    Author : Malin Johansson; Teknisk logistik; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Reshoring; Offshoring; Right-shoring; Survey; Meta-analysis;

    Abstract : Recently, firms have started to bring back once offshored manufacturing activities from far distant locations, an activity referred to as backshoring. The purpose of this thesis is to contribute to the understanding of the backshoring phenomenon by answering four research questions related to different aspects of manufacturing relocation.
