  1. 1. Towards a tunable, wide-band acoustic transducer operating in the quantum regime.

    University essay from KTH/Tillämpad fysik

    Author : Abel Hugot; [2022]
    Keywords : Hybrid quantum systems; Acoustics; Impedance matching; SQUIDs; Hybrida kvantsystem; Akustik; Impedansanpassning; SQUIDs.;

    Abstract : In the past decade we have seen fast development of new quantum technologies that promise to revolutionise communications and computing. Many different routes are explored to physically implement such quantum technologies. Among others, we can mention superconducting circuits, spin-based devices and photonic devices. READ MORE

    Abstract : The interest towrds machine learning applied to turbulence has experienced a fast-paced growth in the last years. Thanks to deep-learning algorithms, flow-control stratigies have been designed, as well as tools to model and reproduce the most relevant turbulent features. READ MORE

  5. 5. Rheology of dense particle suspensions in linear over-damped flow

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Salar Zamani Salimi; [2021]
    Keywords : ;

    Abstract : Suspensions are composed of mixtures of particles and fluid and are omnipresent in natural phenomena and in industrial processes. While hydrodynamic interactions or lubrication forces between the particles are important in the dilute regime, they become of lesser significance when the concentration is increased, and direct particle contacts become dominant in the rheological response of concentrated suspensions, particularly those close to the maximum volume fraction where the suspension ceases to flow.
