  1. 1. Fault location in resonant earthed medium voltage distribution systems

    Author : Md Zakaria Habib; Nathaniel Taylor; Mohamed F. Abdelfattah; Matti Lehtonen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical distribution; Distribution network; Reliability; SAIDI; Fault location; FL; Fault passage indicator; FPI; Compensated neutral; Resonant earthing; Resonant grounding; Petersen coil; Arc suppression coil.; Distributionsnät; Tillförlitlighet; Fellokalisering; FL; Felpassageindikation; FPI; Kompenserat nät; Spoljordat nät; Petersenspole.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : A major challenge in electric distribution systems is to increase the reliability of the electricity supply in an economical way. At the final medium-voltage level in the system, such as 10 kV or 20 kV, a single feeder may supply tens of medium/low-voltage transformers and hundreds of customers, with many branches of lines and cables where faults can occur.

  2. 2. The Railway Station and The Interregional Traveller - traveller preferences and implications for the planning process

    Author : Cristina Prather Persson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Samhällsvetenskaper; Social sciences; service; location; planning; preferences; railway; station; traveller; Technological sciences; Teknik;

    Abstract : The interregional traveller’s preferences of railway stations, their service provision and location, are of interest in the discussion of station reinvention brought on by the introduction of high speed train traffic. A railway station is created by station as well as societal agents, and can be described as a synthesis of symbolic value, location, traffic, services and stationscape. READ MORE

  3. 3. Exploring Tensions between Appropriability and Openness to Collaboration in Innovation

    Author : Ioana Stefan; Lars Bengtsson; Frishammar Johan; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Appropriability; Openness; Tensions; Open Innovation; Performance; Intellectual Property Rights; Territoriality; Location; Intellectual Property Protection Mechanisms; Paradox; Dilemma; Dialectic; Intelligent industri; Intelligent Industry; Industriell ekonomi och organisation;

    Abstract : Researchers, policy makers and practitioners alike have in recent years acknowledged a growing tendency towards opening up the innovation process by combining internal organizational assets with external actors’ resources. However, opening up the innovation process usually also entails revealing ideas, which may result in misappropriation. READ MORE

  4. 4. Computational Characterization of Mixing in Flows

    Author : Erik D. Svensson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mixing; hyperbolicity; shadowing; finite elements; flow simulation; a priori error estimates; Stokes equations; point location; multigrid; refinements; mixing;

    Abstract : The major theme of this thesis is mathematical aspects of fluid mixing in the case when diffusion is negligible, which is commonly refered to as ’mixing by stirring’ or ’mixing by chaotic advection’ in the engineering literature. In this case the mixing is driven by a velocity field and is characterized by the flow generated by the velocity field. READ MORE

  5. 5. Proximity Matters? Geographical aspects of changing strategies in automotive subcontracting relationships:the case of domestic suppliers to Volvo Troslanda assembly plant

    Author : Anders Larsson; Göteborgs universitet; []
    Keywords : automotive-industry; Hydro-Raufoss Automotive; just-in-time; location; proximity;

    Abstract : This study analyses the significance of geographical proximity in the restructuring process of a domestic subcontractor system in the Swedish automotive industry, using the Volvo Torslanda assembly plant as a case. The focus is on: i) the organisation of buyer-subcontractor relationships, ii) time-related delivery strategies, iii) the significance of geographical proximity. READ MORE
