  1. 1. Modelling the global water cycle – the effect of Mg-sursassite on the amount of globally subducted water

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Nils Benjamin Gies; [2021-07-05]
    Keywords : ;

    Abstract : Subduction of hydrated lithospheric mantle is the most important process regarding the transfer of significant amounts of water to depths exceeding 350 km. Hence, the interplay of the thermal structure withinthe subducted slab together with the PT-stability fields of hydrous ultra-high pressure phases control thedehydration of the slab and the amount of water transported into the deeper mantle.

  2. 2. Quantum thermodynamics explorations with a Hubbard-Holstein dimer

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

    Author : Emil Adam Jonatan Östberg; [2021]
    Keywords : QTD Quantum Thermodynamics Hubbard-Holstein Hubbard Holstein dimer Lanczos Suzuki-Trotter ST Exact diagonalization ED Hysteresis Path dependence Battery Mott-insulator; Physics and Astronomy;

    Abstract : The goal of this project is to characterize the quantum thermodynamics of a Hubbard-Holstein dimer. We explore how the standard formalism of quantum thermodynamics behaves in the context many-body physics. READ MORE

  3. 3. Search for Higgs-like bosons through optimization of top-quark modelling

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Rafael Antonio Lopez; [2021]
    Keywords : ttbar; top quark modelling; BSM; 2HDM S; Higgs-like bosons; ATLAS; HWW; XSh; top estimation; top remodelling; Physics and Astronomy;

    Abstract : Accurate estimations of background processes associated with top-quarks are vital to studies concerned with finding new physics at the Large Hadron Collider (LHC)at CERN. Search for Higgs-like bosons in the ATLAS experiment at LHC was performed by optimising the use of b-jet tagging algorithms and improving on tt backgroundmodelling. READ MORE

  4. 4. Established forest firefighting techniques: A qualitative review of practices among the Swedish fire services.

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Muhammad Humza Khan; [2021]
    Keywords : Forest fires; firefighting techniques; Scientometric analysis; Effectiveness; Questionnaire; Direct attack; Indirect attack; Firelines; Prescribed burning; Aerial firefighting; Flanking; Hot-spotting; Cold trailing.; Technology and Engineering;

    Abstract : Methods and equipment used for fighting forest fires are different from the ones used in urban fires. Generally, the wildfires are intense, require more resources and tend to spread rapidly. READ MORE

  5. 5. 2D & 3D phase retrieval for propagation-based X-ray phase-contrast tomography

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Philip Stjärneblad; [2021]
    Keywords : Propagation-based X-ray phase-contrast tomography; PB-PCT; Propagation-based X-ray phase-contrast Imaging; PB-PCI; 2d phase retrieval; 3d phase retrieval; TIE; sinogram consistency; reconstruction artefacts; Science General;

    Abstract : Propagation-based X-ray phase-contrast tomography is a 3d imaging technique that utilizes two-dimensional projections from different angular views $\theta =[0,\pi]$ to reconstruct the 3D object information. The phase-contrast allows for higher feature contrast than conventional transmission tomography, as the phase interference gives rise to a sharp edge contrast. READ MORE
