  1. 1. Segmentation and differentiation in defence supply chain design : A dynamic purchasing portfolio model for defence procurement

    Författare :Thomas Ekström; Per Hilletofth; Alastair Finlan; Per Skoglund; Lisa Ellram; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; purchasing portfolio model; segmentation and differentiation; segmentation model; supply chain strategy; military logistics; defence procurement; defence supply chain design; modified Delphi study; portföljmodell; segmentering och differentiering; segmenterings-modell; försörjningsstrategi; militär logistik; försvarsanskaffning; utformning av militära försörjningskedjor; modifierad Delphistudie; Krigsvetenskap; War Studies;

    Sammanfattning : An important priority in the current Swedish Defence Bill is to increase the operational warfighting capability of the Swedish Armed Forces, which has implications for the defence supply chain. A recent study suggested that the Swedish Armed Forces should use segmentation of supplies and differentiation of supply chains to enable an affordable supply chain design (SCD). LÄS MER

  3. 2. Epitaxial growth, structure, and thermoelectric properties of CaMn- and V-based oxides

    Författare :Erik Ekström; Per Eklund; Biplab Paul; Fredrik Eriksson; Nini Pryds; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin film; PVD; Oxides; Epitaxy; XRD;

    Sammanfattning : This thesis is focused on physical vapor deposition, epitaxy, and structural characterization of CaMnO3 and VO2. Environmentally friendly and abundant materials are important for energy savings in applications, e.g., thermoelectrics for waste-heat recycling and thermochromic materials for passive indoor-temperature regulation.

  4. 3. Essays on Inequality and Education

    Författare :Erika Ekström; Per-Anders Edin; Peter Fredriksson; Arne Bigsten; Paul Gregg; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Income distribution; Discrimination; Namibia; Vocational education; University enrolment; Unemployment; Adult education; Wage earnings; Nationalekonomi; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of an introduction and four self-contained essays.Essay I examines the contribution of socio-economic variables to Namibian income inequality. I examine the extent to which total income inequality is due to within-group inequality or between-group inequality. Income inequality in Namibia ranks among the highest in the world. LÄS MER

  5. 4. Growth and thermoelectric properties of CaMnO3-based thin films

    Författare :Erik Ekström; Per Eklund; Fredrik Eriksson; Biplab Paul; Erik Lewin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The field of them1oelectrics started in early 19th century. Since the discovery of the Seebeck effect and the Peltier effect, thermoelectric modules have found their way into, mostly, niche applications such as radioisotope thermoelectric generators on space missions. LÄS MER

  7. 5. A Dark Matter Search with AMANDA : Limits on the Muon Flux from Neutralino Annihilations at the Centre of the Earth with 1997-99 Data

    Författare :Patrik Ekström; Per Olof Hulth; Lee Thompson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : The nature of the dark matter in the Universe is one of the greatest mysteries in modern astronomy. The neutralino is a nonbaryonic dark matter candidate in minimal supersymmetric extensions to the standard model of particle physics. LÄS MER
