    Sammanfattning : This thesis, within the subfield of computer science known as computer vision, deals with the use of scale-space analysis in early low-level processing of visual information. The main contributions comprise the following five subjects:The formulation of a scale-space theory for discrete signals. LÄS MER

  5. 4. Borehole sealing with expandable buffer clays in HLW disposal : Lab-scale performance

    Författare :Ting Yang; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Two basically different multibarrier concepts for high-level radioactive waste (HLW) are the often cited KBS-3 V/H concepts, for isolating nuclear waste at 400-600 m depth and Very Deep Boreholes concepts (VDH) for placement at 2000-4000 m depth. Both make use of expandable clay as isolating medium of canisters with HLW and as backfill material in shafts and tunnels in repositories for safe disposal of such waste. LÄS MER

  7. 5. Landscape from space : geographical aspects on scale, regionalization and change detection

    Författare :Ola Hall; Risto Kalliola; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Regionalization; Scale; Change detection; Multiscale analysis; Objectspecific analysis; Watershed transformation; Landscape; Satellite data; Geography; Complex systems theory; Fuzzy set theory; Multicriteria-evaluation.; Human geography; Kulturgeografi; Human Geography; kulturgeografi;

    Sammanfattning : Landscapes are complex systems composed of multiscale hierarchically organized entities that interact within unique spatial and temporal scales. These interactions result in scaledependent spatial patterns that visually change depending upon the scale at which they are observed. LÄS MER
