  1. 1. Generalized super-resolution of 4D Flow MRI : extending capabilities using ensemble learning

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Adam Hjalmarsson; Leon Ericsson; [2023]
    Nyckelord :4D Flow MRI; Ensemble learning; Super-resolution; Machine learning; Neural networks; 4DFlowNet;

    Sammanfattning : 4D Flow Magnet Resonance Imaging (4D Flow MRI) is a novel non-invasive technique for imaging of cardiovascular blood flow. However, when utilized as a stand-alone analysis method, 4D Flow MRI has certain limitations including limited spatial resolution and noise artefacts, motivating the application of dedicated post-processing tools.

  3. 2. Dynamic Covariance Modelling Using Generalised Wishart Processes

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Fredrik Nilsson; [2023]
    Nyckelord :Covariance matrix; generalised Wishart process; Bayesian inference; Markov chain Monte Carlo; Hamiltonian Monte Carlo; Mathematics and Statistics;

    Sammanfattning : Modern portfolio theory was pioneered by Markowitz who formulated the mean-variance problem, without which any discussion on quantitative approaches to portfolio selection would be incomplete. The framework boils down to finding the expected return $\mu$ and covariance $\Sigma$, after which the solution is proportional to $\Sigma^{-1}\mu$. LÄS MER

  4. 3. JÄMFÖRELSE AV TVÅDIMENSIONELL OCH TREDIMENSIONELL ANALYS FÖR BESTÄMNING AV VOLYM OCH EJEKTIONSFRAKTION

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Manar Kobeissi; [2023]
    Nyckelord :2D ECHO; 3D ECHO; Dynamic Heart Model; echocardiography; ejection fraction; Tomtec.; 2D EKO; 3D EKO; ejektionsfraktion; dynamisk hjärtmodell; ekokardiografi; Tomtec.;

    Sammanfattning : Ekokardiografi (EKO) är en vanlig metod som används för bedömning och uppföljning av eventuella hjärtsjukdomar. Idag är tvådimensionell (2D) EKO standardmetoden för bestämning av slutdiastolisk volym (EDV), slutsystolisk volym (ESV) och ejektionsfraktionen (EF). LÄS MER

  5. 4. Optimisation of a LOX/Ethanol rocket engine ignition

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Pierre Collard; [2022]
    Nyckelord :;

    Sammanfattning : For more than half a century, humanity has achieved the feat of extracting itself from the earth's atmosphere and sailing into space, broadening the spectrum of knowledge and curiosity. Although space market seemed mastered and stable the arrival of new private players has reorganized the sector through new technological choices. LÄS MER
