  1. 21. Data-driven Discovery of Real-time Road Compaction Parameters

    University essay from KTH/Matematisk statistik

    Author : Yuqi Shao; [2022]
    Keywords : statistics; machine learning; road compaction; statistik; maskininlärning; vägpackning;

    Abstract : Road compaction is the last and important stage in road construction. Both under-compaction and over-compaction are inappropriate and may lead to road failures. Intelligent compactors has enabled data gathering and edge computing functionalities, which introduces possibilities in data-driven compaction control. READ MORE

  3. 22. Quantum Computing in Nuclear Physics

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Luca Bernecker; [2022]
    Keywords : quantum computing; nuclear physics; qubits; theoretical physics; Physics and Astronomy;

    Abstract : In this thesis, we investigate many–body systems using simulations of quan- tum computers. Quantum computing is a computational paradigm based on qubits which are defined in a Hilbert space instead of the familiar binary bits. READ MORE

  4. 23. Rotational Properties of Lee-Huang-Yang Bosonic Condensates from One to Two Dimensions

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Hjalmar Holmström; [2022]
    Keywords : BEC; Bose-Einstein condensate; quantum fluid; Quantum mechanics; LHY; LHY-fluid; Lee-Huang-Yang; Rotating BEC; BEC droplet; Physics and Astronomy;

    Abstract : This thesis covers the work of a numerical examination of the rotational properties of a two-component Bose-Einstein condensate (BEC) utilizing the beyond mean-field extended Gross-Pitaevskii equation for a specified set of parameters. These parameters are chosen to cancel the strength of the mean-field interaction, which makes the system predominantly governed by the next order beyond the mean-field Lee-Huang-Yang (LHY) term.

  5. 24. Power Reconstruction Uncertainties in European Pressurized Reactor Impact of Partial. Unavailability of Sensors

    University essay from KTH/Fysik

    Author : Matthieu Causse; [2022]
    Keywords : ;

    Abstract : This study is part of a theme related to the physical tests performed on the core of nuclear reactors and particularly the EPR, a new French reactor under construction on the Flamanville site. The peaking factors of this reactor are continuously monitored by an instrumentation located both inside (collectrons) and outside (external fission chambers) the core. READ MORE

  6. 25. Doping Layers in Quantum Cascade Lasers: A study in doping density, position and migration effects

    University essay from Lunds universitet/Matematisk fysik

    Author : Josefin Reftlér; [2022]
    Keywords : Physics and Astronomy;

    Abstract : Quantum Cascade Lasers (QCLs) consist of several semiconductor materi- als sandwiched together. The QCL achieves stimulated emission in the mid-IR (m-IR) to the THz region of the electromagnetic spectrum by inter-subband transitions. These parts of the electromagnetic spectrum are hard to lase in with conventional means. READ MORE
