    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation; Innovation determinant; Innovation effect; Firm; Region; Sweden; Industry life cycle; Cluster life cycle; Export;

    Sammanfattning : Innovation and technological change is the major factor of production, renewal, and competitiveness of firms and nations in the contemporary “knowledge economy”. The overall purpose of this dissertation is to investigate the innovative behavior of firms in various sectors and regions. LÄS MER

  3. 2. Östersjöområdet : Studier av interaktion och barriärer

    Författare :Jan-Henrik Nilsson; Institutionen för tjänstevetenskap; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; European integration; Baltic Sea Area; interaction; aviation; region; territories; barriers; Social geography; systems of cities; region; Socialgeografi;

    Sammanfattning : The geopolitical transformation after 1989 had radical territorial consequences in almost all parts of East-Central Europe. In the Baltic Sea Area alone, five new states were formed. The process of European integration became a priotity on the agenda. The concept of integration describes a process of uniting two or more entities. LÄS MER

  4. 3. Contributions to 3D Image Analysis using Discrete Methods and Fuzzy Techniques : With Focus on Images from Cryo-Electron Tomography

    Författare :Magnus Gedda; Ewert Bengtsson; Stina Svensson; Carolina Wählby; Punam Saha; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; digital image analysis; 3D; fuzzy; algorithms; grey-weighted distance; region growing; electron tomography; tracing; fluorescence microscopy; Datoriserad bildanalys; Computerized Image Analysis;

    Sammanfattning : With the emergence of new imaging techniques, researchers are always eager to push the boundaries by examining objects either smaller or further away than what was previously possible. The development of image analysis techniques has greatly helped to introduce objectivity and coherence in measurements and decision making. LÄS MER

  5. 4. Planar segmentation for Geometric Reverse Engineering using data from a laser profile scanner mounted on an industrial robot

    Författare :Mohamed Rahayem; Björn Arén; Johan Kjellander; Mathias Broxvall; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geometric Reverse Engineering; 3D measurement systems; laser scanner; planar segmentation; region-growing; Computer and systems science; Data- och systemvetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : Laser scanners in combination with devices for accurate orientation like Coordinate Measuring Machines (CMM) are often used in Geometric Reverse Engineering (GRE) to measure point data. The industrial robot as a device for orientation has relatively low accuracy but the advantage of being numerically controlled, fast, flexible, rather cheap and compatible with industrial environments.

  7. 5. Företag i perifera regioner : Fallstudier av företagartradition, företagsmiljö och företags framväxt i Norrbottens inland

    Författare :Elisabeth Sundin; Leif Lindmark; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; buying behavior; case studies; dependency theory; developing industry; economic tradition; entrepreneurship; external control; growing firms; historical method; industrial environment; linkage patterns; local control; northern Sweden; peripheral regions; prefabricated houses; small firms; spirit of enterprise; staple theory; underdeveloped regions; Företag; Sverige; Norrbotten;

    Sammanfattning : This is a study of how industries develop in regions that are industrially weak, exemplified by Norrbotten, the northernmost province of Sweden. Developing industries are represented by three companies manufacturing prefabricated wooden houses, situated in the municipalities Övertorneå, Kalix (Morjärv) and Älvsbyn in the interior of Norrbotten.
