    Sammanfattning : In the rapidly growing wind energy market, regions with cold climates are currently in the spotlight owing to their abundance of wind resources. However, the operation of wind turbines in cold climate conditions is challenged by serious icing problems. LÄS MER

  3. 2. Exploring persistent homology as a method for capturing functional connectivity differences in Parkinson’s Disease.

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Naomi Hulst; [2022]
    Nyckelord :persistent homology; topological data analysis; computational topology; parkinson s disease; parkinson; functional connectivity; stable rank; ihållande homologi; topologisk data analys; beräknings topologi; Parkinsons sjukdom; parkinson; funktionell konnektivitet; stable ranks;

    Sammanfattning : Parkinson’s Disease (PD) is the fastest growing neurodegenerative disease, currently affecting two to three percent of the population over 65. Studying functional connectivity (FC) in PD patients may provide new insights into how the disease alters brain organization in different subjects. LÄS MER

  5. 4. Structural optimization of electronic packages using DOE

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Robin Johansson; [2020]
    Nyckelord :Design of experiments; DOE; Structural optimization; Electronic packages; DOE; Försöksplanering; Strukturoptimering;

    Sammanfattning : The reliability of a mechanical system containing electronic packages is highly affectedby the environment the system is stationed in. The difference and fluctuationsbetween the ambient temperature and the operating temperature of the electronicpackage cause accumulation of inelastic strains in the package components thusdecreasing the service life.
