  3. 2. Towards Increased Energy Efficiency in Swedish Industry : Barriers, Driving Forces & Policies

    Författare :Patrik Thollander; Mats Söderström; Magnus Karlsson; Jenny Palm; Paolo Bertoldi; Linköpings universitet; []
    Nyckelord :Industrial energy efficiency; barriers; driving forces; investment decision support; energy policies; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Industrial energy efficiency is one of the most important means of reducing the threat of increased global warming. A higheruse of electricity than their European competitors, together with increased energy costs due to increasing energy prices in Swedish industry have negative impacts on results and competitiveness.

  4. 3. Analysis and control of magnetic forces in synchronous machines

    Författare :J. J. Pérez-Loya; Urban Lundin; Anouar Belahcen; Uppsala universitet; []
    Nyckelord :eccentricity; electromagnetics; electromagnetic forces; excitation; magnetic fields; magnetic forces; magnetic thrust bearing; rotor drive; split rotor; starting; synchronous generators; synchronous machines; synchronous motors; unbalanced magnetic pull; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : In a synchronous machine, radial, tangential, and axial forces are generated. In this thesis, three different technologies to control them are proposed. The first one, involves the utilization of the radial forces that arise between the rotor and the stator. LÄS MER

  5. 4. Outsourcing strategies for wood product manufactering firms : driving forces and strategic development

    Författare :Daniel Fransson; Linköpings universitet; []
    Nyckelord :Outsourcing; driving forces; strategic development; wood product manufacturing firms; case studies; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : In this thesis outsourcing in the wood product manufacturing sector (WPM) is studied. More specifically, the study aims to describe and analyse outsourcing strategies for firms in the WPM industries (door, floor and window). LÄS MER

  7. 5. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces

    Författare :Petra M Hansson; Per M. Claesson; Agne Swerin; Adam C Simonsen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrophobic surface; superhydrophobic surface; atomic force microscopy; surface forces; capillary forces; cavitaion; surface roughness; friction; wetting; confocal Raman; contact angles; surface preparation; Langmuir-Blodgett;

    Sammanfattning : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.
