  1. 1. ATLAS DATABASES OF HUMAN BRAIN ANATOMY: QUALITATIVE AND QUANTITATIVE COMPARISON

    Master-uppsats,

    Författare :Amanda Philipsson Franzén; [2021-01-11]
    Nyckelord :Medical physics; Brain atlas concordance problem; Quantitative comparison; Qualitative comparison; Hammersmith; 2012 MICCAI Multi-Atlas Labelling Challenge Data;

    Sammanfattning : The purpose of this study was to quantitatively and qualitatively compare the two brain atlases databases, Hammersmith and 2012 MICCAI Multi-Atlas Labelling Challenge data, by developing a quantitative method.TheoryAnatomical atlases of the human brain provide reference information about its structure.

  2. 2. Radiation effects on wide bandgap semiconductor devices

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Patric Elf; [2020]
    Nyckelord :applied physics;

    Sammanfattning : Gallium nitride (GaN) based high-electron-mobility transistors (HEMTs) are used in a wide variety of areas, such as 5G, automotive, aeronautics/astronautics and sensing elds ranging from chemical, mechanical, biological to optical applications. Owing superior material properties, the GaN based HEMTs are especially useful in harsh operation environments e. LÄS MER

  3. 3. Occlusion method to obtain saliency maps for CNN

    Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik

    Författare :Thomas Eriksson; [2020]
    Nyckelord :Saliency map; explanatory model; process focussed XAI; MNIST; image classifying CNN.; Physics and Astronomy;

    Sammanfattning : This Bachelor project will study convolutional neural networks created for image classification. Furthermore, it will specifically use an explanatory model for how the network decided a certain classification output. This is to increase the interpretability of the network. LÄS MER

  4. 4. Correcting biological infrared spectroscopy data for atmospheric gases and Mie scattering

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik

    Författare :Stéphan Pissot; [2020]
    Nyckelord :FTIR; spectroscopy; chemometrics; infrared absorption microscopy; atmospheric correction; scattering correction; Physics and Astronomy;

    Sammanfattning : Infrared absorption microscopy is a powerful chemometric tool with a wide variety of applications. It is, however, subject to considerable disturbances from atmospheric gases and scattering effects. LÄS MER

  5. 5. Advanced Clinical Data Processing: A Predictive Maintenance Model for Anesthesia Machines

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Kerim Numanovic; [2020]
    Nyckelord :Appled Physics; Tillämpad fysik;

    Sammanfattning : The maintenance of medical devices is of great importance to ensure that the devices are stable, well-functioning, and safe to use. The current method of maintenance, which is called preventive maintenance, has its advantages but can be problematic both from an operators’ and a manufacturers’ side. LÄS MER
