  4. 18. Multi-scale fabric evolution during hydro-mechanical probing of fine-grained soils

    Författare :Georgios Birmpilis; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray Computed Tomography; clay fabric; geomechanical testing; sensitive clays; X-ray Scattering;

    Sammanfattning : The majority of the studies on sensitive clays so far have focused on the hydro-mechanical response at engineering scale, using concepts from continuum mechanics. The fundamental mechanisms at particle scale, underpinning the emerging response, have so far been studied with post mortem analyses. LÄS MER

  5. 19. Virtual histology by laboratory x-ray phase-contrast tomography

    Författare :Jenny Romell; Hans Hertz; Anna Burvall; Julia Herzen; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Detailed imaging of biological samples is central to different fields of research, as well as for clinical pathology. Classical histology, using light- orelectron microscopy, can generate high-resolution images but is destructive and only gives two-dimensional information. LÄS MER

  7. 20. Methods of image acquisition and calibration for x-ray computed tomography

    Författare :Martin Sjölin; Mats Danielsson; J. Webster Stayman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Technology; Medicinsk teknologi;

    Sammanfattning : X-ray computed tomography (CT) is a common medical imaging device for acquiring high-resolution 3D images of the interior of the human body. The images are formed by mathematical reconstruction from hundreds of planar x-ray images that have been acquired during less then a second. LÄS MER
