  2. 6. Tribology of stamping : the influence of designed steel sheet surface topography on friction

    Author : Daniel Wiklund; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel sheet; tribology; surface topography; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : Tribology is the science of friction, wear, and lubrication; the interaction of surfaces in relative motion. The tribological conditions in sheet metal forming influences the flow of material in forming operations, the strain distributions of sheet material, extent of wear, and thereby the quality of products.

  5. 8. Surface guided radiotherapy

    Author : Malin Kügele; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface guided radiotherapy; DIBH; SGRT; radiotherapy; patient positioning; intra-fraction motion; surface imaging; treatment planning; SGRT; surface guided radiotherapy; intra-fraction motion; DIBH; patient positioning; treatment planning; surface imaging;

    Abstract : Modern radiotherapy aims to treat the decease while minimizing the radiation dose to the adjacent normal tissue, to minimize acute and late effects of the treatment. The foremost technological approaches have been intensity modulated radiotherapy (IMRT) and intensity modulated proton therapy (IMPT) in combination with image guided radiotherapy (IGRT). READ MORE

  6. 9. A surface approach to understanding the dissolution of fluorite type materials : Implications for mineral dissolution kinetic models

    Author : José Ricardo Assunção Godinho; Sandra Piazolo; Andreas Lüttge; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolution; topography; fluorite; surface; geokemi; Geochemistry;

    Abstract : Traditional dissolution models are based in the analyses of bulk solution compositions and ignore the fact that different sites of a surface dissolve at different rates. Consequently, the variation of surface area and surface reactivity during dissolution are not considered for the calculation of the overall dissolution rate, which is expected to remain constant with time.

  7. 10. On Surface Topography of Steel Sheet for Car Bodies

    Author : Magnus Jonasson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paint appearance; forming; steel sheet; bearing area; 3D surface roughness; area parameters; ball filter; friction; surface topography;

    Abstract : This thesis is a contribution to the scientific area of surface topography on sheet metal surfaces. The studies are restricted to exploring the influence of the steel sheet,s surface topography on forming properties and on appearance after painting. READ MORE
