    Sammanfattning : Ion sensing represents a grand research challenge. It finds a vast variety of applications in, e.g., gas sensing for domestic gases and ion detection in electrolytes for chemical-biological-medical monitoring. LÄS MER

  5. 24. Digital Image Analysis of Cells : Applications in 2D, 3D and Time

    Författare :Amalka Pinidiyaarachchi; Carolina Wählby; Ewert Bengtsson; Arvid Lundervold; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital image analysis; microscopy; fluorescent staining; watershed segmentation; sub-cellular localization; point-like signals; wavelets; cell confluence; cytology; color spaces.; Image analysis; Bildanalys;

    Sammanfattning : Light microscopes are essential research tools in biology and medicine. Cell and tissue staining methods have improved immensely over the years and microscopes are now equipped with digital image acquisition capabilities. The image data produced require development of specialized analysis methods. LÄS MER

  7. 25. Galna kameror och barns virtuella bildseende, bildtänkande och filmgörande i förskolan

    Författare :Maria Olsson; Anne-Li Lindgren; Anna Palmer; Simon Ceder; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; children; preschool; children’s filmmaking; image vision; digital videography; Deleuze’s film philosophy; transcendental empiricism; the crystal-image; barn; förskola; barns filmgörande; bildseende; digital videografi; Deleuzes filmfilosofi; transcendental empirism; kristallbild; Early Childhood Education; förskoledidaktik;

    Sammanfattning : The aim of this thesis is to contribute knowledge about children’s image-vision, image-thinking and image- and filmmaking in preschool, through a collaboration with children and digital film technology, and about Gilles Deleuze’s film philosophy (1989) as well as digital videography and the methodology created in the research process. The empirical production was carried out as a digital decentralized videography, according to Pink et al. LÄS MER
