  1. 1. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

    Master-uppsats, KTH/Materialvetenskap

    Författare :Helena Ek Jendrny; [2023]
    Nyckelord :AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

    Sammanfattning : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. LÄS MER

  3. 2. Tjockleksmätning av sprutbetong med RFID

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Rutger Brattström; [2020]
    Nyckelord :RFID; Betong; Sprutbetong;

    Sammanfattning : This project has studied if RFID technology can be used to measure the thickness of shotcrete applied to walls, such as in tunnel construction. An RFID tag can be placed on the wall before the shotcrete is applied. When the RFID reader contacts the tag through the shotcrete the loss in signal strength can be measured. LÄS MER

  4. 3. Numerical simulations of the Dynamic Beam Equation in discontinuous media

    Kandidat-uppsats, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Niklas Wik; David Niemelä; Valter Wagner Zethrin; [2020]
    Nyckelord :Dynamic beam equation; DBE; SAT; projection; SBP;

    Sammanfattning : The study examines the Projection method and the simultaneousapproximation-term (SAT) method as boundary treatment for the dynamic beam equation using summation-by-parts (SBP) operators for handling the inner domain. The methods are examined for both the homogeneous constant coefficient case, and the inhomogeneous piecewise constant coefficient case with a coupled interface. LÄS MER

  5. 4. Acoustophoretic manipulation of sub-micron particles

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :David van Assche; [2017]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Microchannel acoustophoresis is a technique which uses acoustically induced forces to translate particles in a microchannel. Its use in biological applications is increasing. Using acoustophoresis to precisely manipulate bioparticles such as yeast, blood cells and cancer cells gives the technique great potential. LÄS MER

  7. 5. Towards monodisperse Silicon Nanocrystals: density gradient centrifugation applied on commercial gold nanoparticles

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Faraz Khavari; [2016]
    Nyckelord :Silicon Nanocrystals; density gradient centrifugation; gold nanoparticles;

    Sammanfattning : The application of silicon nanocrystals as non-toxic bio-labels and downconverters requires their uniform size distribution in order to minimize the inhomogeneous broadening of the photoluminescence peak. In this thesis, we set the basis for their size-separation via the density-gradient centrifugation method. LÄS MER
