    Sammanfattning : This master thesis presents an analogue peak holder circuit design aimed at facilitating the non-invasive inspection of the ageing process in electric drives. The ageing process of electric drives is a crucial aspect that demands accurate monitoring to ensure their long-term performance and reliability. LÄS MER

  3. 2. Integration of microfluidic sample handlingwith ultra-sensitive magnetic bioassay usinghigh-Tc Superconducting Quantum InterferenceDevice readout

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Emil Eriksson; [2016]
    Nyckelord :;

    Sammanfattning : Immunoassays are a very sensitive molecular diagnostics technique that uses biochemical reactions to measure concentration of biomolecules in a solution. ELISA is one of the most commonly used type, based on fluorescence, in routine medicaldiagnostics. It is time consuming and requires relatively large sample volumes. LÄS MER

  4. 3. Experimental study on turbulent pipe flow

    Master-uppsats, KTH/Mekanik

    Författare :Marco Ferro; [2012]
    Nyckelord :;

    Sammanfattning : Fully developed turbulent pipe ows have been studied experimentally for more than a century and for more than two decades by means of Direct Numerical Simulations, nonetheless there are still unresolved and of fundamental nature issues. Among those are the scaling of the mean velocity pro le or the question whether the near-wall peak in the variance pro le is Reynolds number invariant. LÄS MER
