  1. 6. A Study of the Adhesion Strength of Plasma Sprayed Coatings

    Författare :Fouzi Bahbou; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Splat.; Surface roughness; Mechanical anchoring; Grit blasting; Adhesion strength; Protal® process; Fractal analysis; Thermal spraying; Coating; Surface pre-treatment;

    Sammanfattning : Surface preparation prior to thermal spraying is a key factor in ensuring a good adhesion of the coating onto the part to be coated. Surface pre-treatment conditions and methods have mainly been developed experimentally and have changed little over the years. LÄS MER

  4. 8. Topological and Scaling Analysis of Geospatial Big Data

    Författare :Ding Ma; Bin Jiang; Shaowen Wang; Högskolan i Gävle; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Third definition of fractal; scaling; topology; power law; head tail breaks; ht-index; complex network; geospatial big data; natural cities; natural streets; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : Geographic information science and systems face challenges related to understanding the instinctive heterogeneity of geographic space, since conventional geospatial analysis is mainly founded on Euclidean geometry and Gaussian statistics. This thesis adopts a new paradigm, based on fractal geometry and Paretian statistics for geospatial analysis. LÄS MER

  5. 9. Fractal analysis and surface characterization by atomic force microscopy and other methods

    Författare :Anders Mannelquist; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Fysik;

    Sammanfattning : This licentiate thesis focuses on fractal analysis of surfaces measured with atomic force microscopy (AFM) and other microscopic methods, and the correlation between fractal dimensions and tensile strength for pre-treated stainless-steel surfaces. The disadvantage is that the probe biases the image and the roughness measurement. LÄS MER
