  1. 1. Electronic states of adsorbates and insulating overlayers on metal surfaces

    Författare :Fredrik Olsson; Chalmers University of Technology; []
    Nyckelord :Shockley surface states; local density of states; scanning tunneling microscope; chemisorption; sodium chloride; noble metals; image states; electronic states; density functional theory;

    Sammanfattning : Electronic states of adsorbates and insulating overlayers provide a wealth of scientifically interesting phenomena with great technological importance. Interesting phenomena arise, for example, from the interaction of electronic states of an adsorbate with the continuum of metal electron states, both propagating bulk states and surface states.

  2. 2. Super resolution optical imaging – image analysis, multicolor development and biological applications

    Författare :Daniel Rönnlund; Jerker Widengren; Christian Eggeling; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Stimulated emission depletion STED microscopy; nanoscopy; multicolor; image analysis; diagnostics; cancer; metastasis; Biologisk fysik; Biological Physics;

    Sammanfattning : This thesis focuses on super resolution STED optical imaging. STED provides a wealth of new informational content to the acquired images by using stimulated emission to surpass the diffraction limit in optical fluorescence microscopy. LÄS MER

  3. 3. Medborgarskapande på olika villkor : Självbilder, skolkoder och syn på kunskap i den svenska gymnasieskolan

    Författare :SOFIE GUSTAFSSON; Statsvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Citizenship; upper secondary schools; power; field work; school code; self-image; learning;

    Sammanfattning : Citizens are not born, they are made. Based on fieldwork in two upper-secondary school classes in Sweden – an Introductory Programme class and a Social Science Programme class – this dissertation focuses on how pupils form their identities as citizens in a democratic society.

  4. 4. Segmentation of Laser Range Radar Images using Hidden Markov Field Models

    Författare :Predrag Pucar; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Segmentation; Images; Model based stochastic techniques; Image processing; Demanding algorithms; Hidden Markov model; Estimation; Automatic control; Reglerteknik;

    Sammanfattning : Segmentation of images in the context of model based stochastic techniques is connected with high, very often unpracticle computational complexity. The objective with this thesis is to take the models used in model based image processing, simplify and use them in suboptimal, but not computationally demanding algorithms. LÄS MER

  5. 5. Temporal Modulation in Fluorescence Spectroscopy and Imaging for Biological Applications

    Författare :Gustav Persson; Jerker Widengren; Jörg Enderlein; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; fluorescence; spectroscopy; microscopy; modulated excitation; intensity modulation; fluorescence correlation spectroscopy; transient states; molecular kinetics; Physics; Fysik;

    Sammanfattning : This thesis explores the benefits of intensity modulation for the purpose of extending the range of applications of fluorescence spectroscopy and imaging in cellular and molecular biology and medicine. Long-lived transient states of fluorescent molecules can, because of their long lifetimes, be used to detect subtle changes in the microenvironment of the molecule. LÄS MER
