  1. 1. High-resolution imaging of kidney tissue samples

    Författare :David Unnersjö-Jess; Hans Blom; Lena Scott; Hjalmar Brismar; Peter Hansell; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Super Resolution Microscopy; Kidney; Imaging; Fluorescence; Kidney development; Calcium; Biological Physics; Biologisk fysik;

    Sammanfattning : The kidney is one of the most important and complex organs in the human body, filtering hundreds of litres of blood daily. Kidney disease is one of the fastest growing causes of death in the modern world, and this motivates extensive research for better understanding the function of the kidney in health and disease.

  3. 2. High Resolution Analysis of Halftone Prints : A Colorimetric and Multispectral Study

    Författare :Daniel Nyström; Björn Kruse; Markku Hauta- Kasari; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Color imaging; Multispectral imaging; Halftone print; Dot gain; Image analysis; Bildanalys;

    Sammanfattning : To reproduce color images in print, the continuous tone image is first transformed into a binary halftone image, producing various colors by discrete dots with varying area coverage. In halftone prints on paper, physical and optical dot gains generally occur, making the print look darker than expected, and making the modeling of halftone color reproduction a challenge. LÄS MER

  4. 3. High-resolution biomedical phase-contrast tomography

    Författare :William Twengström; Hans Hertz; Anna Burvall; Marco Stampanoni; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; x-ray; x-ray imaging; biomedical; phase contrast; tomography; zebrafish; coronary artery; virtual histology; ring artifacts; phase retrieval; mummy; Fysik; Physics;

    Sammanfattning : Improved three-dimensional biomedical imaging can give a better understanding of tissue structure, growth and diseases. Most present imaging techniques that provide cellular spatial resolution are based on visible or infrared light. These methods cannot image deeper than a millimeter into tissue. LÄS MER

  5. 4. Urban Land-cover Mapping with High-resolution Spaceborne SAR Data

    Författare :Hongtao Hu; Yifang Ban; Johan Fransson; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; High-resolution; RADARSAT-1 SAR; RADARSAT-2 SAR; Urban Land Cover; Object-based Classification; Neural Network; Support Vector Machines.; Remote sensing; Fjärranalys;

    Sammanfattning : Urban areas around the world are changing constantly and therefore it is necessary to update urban land cover maps regularly. Remote sensing techniques have been used to monitor changes and update land-use/land-cover information in urban areas for decades. Optical imaging systems have received most of the attention in urban studies. LÄS MER

  7. 5. High-resolution radio imaging of galaxy nuclei

    Författare :Eskil Varenius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arp220; star formation; NGC4418; M82;

    Sammanfattning : Star formation and galaxy evolution are intimately linked together. A detailed understanding of the environment where stars form may help us explain the differences we see between galaxies today and at earlier times in the history of the Universe. LÄS MER
