    Sammanfattning : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and product quality. Other reasons for using industrial robots are cost saving, and elimination of hazardous and unpleasant work. LÄS MER

  4. 13. Advancing Upconversion Emissions for Biomedical Imaging

    Författare :Haichun Liu; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; upconverting nanoparticles; luminescence; fluorescence; inverse problem; biomedical optics; biomedical imaging; photon migration; upconversion; tomography; saturation; Fysicumarkivet A:2014:Liu;

    Sammanfattning : During the past decade, upconverting nanoparticles (UCNPs) doped with rare earth ions have become an important class of fluorescence contrast agents for molecular imaging, due to their unique properties. Their property of anti-Stokes luminescence, with both the excitation and emission wavelengths close to the optimal for biomedical imaging, has been extensively explored in various biomedical applications.

  5. 14. Model-based Approaches to Diffuse Optical Imaging and Dosimetry

    Författare :Johan Axelsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photodynamic therapy; diffuse light propagation; fluorescence; imaging; dosimetry; inverse problem;

    Sammanfattning : The work within this thesis investigates Photodynamic therapy and Fluorescence imaging for therapeutics and visualization of deeply embedded lesions. Photodynamic therapy (PDT) is a cancer treatment modality that can eradicate tumors when light, a photosensible drug and oxygen are present. LÄS MER

  7. 15. Extending the inverse vehicle propulsion simulation concept - to improve simulation performance

    Författare :Anders Fröberg; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Drive cycle simulations of longitudinal vehicle models is an important tool for design and analysis of power trains. On the market today there are several tools for such simulations, and these tools use mainly two different methods of simulation, forward dynamic or quasi-static inverse simulation. LÄS MER
