  1. 1. Turbulent Boundary Layers Modelling with Deep Operator Networks

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Yu-Cheng Lu; [2023]
    Nyckelord :Turbulent Boundary Layers; Pressure Gradient; Composite Profiles; Deep Operator Networks; Sensitivity Analysis Nyckelord på svenska;

    Sammanfattning : This thesis project aims to advance the modelling of pressure gradient turbulent boundary layers (PG TBLs) and offer new insights into TBLs modelling. Previous analytical studies have explored various mathematical models, but this research introduces an extended unstacked Deep Operator Networks (DeepONets) architecture with double outputs and five branch parameters.

  3. 2. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Carl Holmquist; [2023]
    Nyckelord :Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

    Sammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER

  5. 4. The effect of time-restricted feeding on glycemic biomarkers : A literature study

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Henrik Bo Pedersen; [2020]
    Nyckelord :Intermittent fasting; time-restricted feeding; type 2 diabetes mellitus; prediabetes; metabolic disorders; fasting glucose -insulin; mean glucose; HbA1c; postprandial glucose -insulin response; insulin sensitivity; insulin resistance; β-cell function;

    Sammanfattning : Background: The prevalence of diabetes and obesity has been on the rise for many years and the search for new and effective dietetic solutions aiming at reducing calories, reducing body mass and improving diabetes has been ongoing. Currently, the intermittent fasting diet - the practice of alternating periods of eating and fasting - is gaining popularity. LÄS MER

  7. 5. Geometry dependency of cerebral arterial pressure, and estimation of wall shear stress in patients with carotid stenosis: a CFD approach

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Josef Odevik; [2020]
    Nyckelord :Carotid stenosis; Geometry dependency; Arterial pressure; Atherosclerosis; Wall shear stress; Computational fluid dynamics; Karotid stenos; Geometriberoende; Artärtryck; Åderförkalkning; Skjuvkraft; Numeriska flödesberäkningar;

    Sammanfattning : This thesis have investigated how the cerebral arterial pressure can be estimated using computational fluid dynamics (CFD). Specifically, a sensitivity study of how the blood vessel diameter affects the arterial pressure in patients with carotid stenosis, has been conducted. LÄS MER
