  1. 6. Optical spectroscopy and fluorescence imaging for cancer diagnostics

    Författare :Pontus Svenmarker; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biomedical optics; Diffuse-reflection spectroscopy; Upconverting nanoparticles; Inverse problem; Fluorescence; Tomography; Imaging; Scattering media; Photon migration; Fysicumarkivet A:2012:Svenmarker;

    Sammanfattning : This work presents optical methods for diagnosing cancer. A complementary method for diagnosing eye cancer was investigated using a technique developed within this work named transscleral optical spectroscopy (TOS). LÄS MER

  2. 7. Seismic Studies of Paleozoic Orogens in SW Iberia and the Middle Urals

    Författare :Artem Kashubin; Christopher Juhlin; Lars Nielsen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Reflection seismics; Traveltime tomography; Uralian orogeny; Variscan orogeny; Crustal structure; Geophysics; Geofysik;

    Sammanfattning : Controlled source seismic methods were employed in this study to investigate the reflectivity and velocity structure of two Hercynian orogens – the Uralides and Variscides. Conventional common depth point (CDP) sections from five reflection seismic campaigns and a velocity model obtained from tomographic inversion of wide-angle observations were the main datasets studied from the Middle Urals.

  3. 8. Seismic imaging of deep crustal reflectivity in Sweden and Iceland

    Författare :Niklas Juhojuntti; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; seismic; reflectivity; Moho; crust; signal; Geofysik; Geophysics; Geofysik; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : Seismic reflection profiling, originally developed by the petroleum industry, was adapted to systematic imaging of deep structures some 25 years ago. In continental areas, these measurements often show weakly reflective upper crust and strongly reflective lower crust. LÄS MER

  4. 9. Shape and surface characterization using diffused light

    Författare :Sara Rosendahl; Pablo Ruiz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : Diffuse reflection from various surfaces have been studied using several different methods in order to draw conclusions about the surfaces. First of all the aim was to perform fast and accurate shape measurements of molded steel objects on-line in a production system. LÄS MER

  5. 10. Structured Metallic Films for Enhanced Light Transmission and Absorption

    Författare :Reyhaneh Soltanmoradi; Min Yan; Sanshui Xiao; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Photonic devices such as light emitters, detectors, solar cells etc. are playing increasingly important roles in modern society. Yet their structures and designs are still under constant improvement, driven mostly by advances in material science and progress in integration techniques. LÄS MER
