  1. 1. Challenges and strategies of teaching swedish to low – literacy skilled immigrants

    Master-uppsats, Göteborgs universitet/Institutionen för pedagogik och specialpedagogik

    Författare :Saba Monirzadeh; [2023-06-21]
    Nyckelord :Low-literate adult; teaching challenges; Swedish for Immigrants; Teaching strategies;

    Sammanfattning : Aim: The present study aims to investigate the challenges SFI teachers face when teaching basic Swedish to low-literacy skilled immigrants, and the strategies they implement to teach these groups. Particularly, this study looks for any indications of Vygotsky’s sociocultural theory (SCT) in the teaching methods used while teaching SFI to individuals who lack literacy. LÄS MER

  3. 2. Achieving Sustainability in Complex Multi-Tier Supply Chains: The Role of Supply Chain Visibility and Transparency in Responsible Sourcing of Critical Minerals

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Ekaterina Pikuleva; [2023]
    Nyckelord :critical minerals; supply chain transparency; supply chain visibility; sustainable supply chain management; traceability; Social Sciences;

    Sammanfattning : There is growing pressure from stakeholders on global corporations to ensure the sustainability of their products throughout the supply chain. At the same time, due to the high complexity and dynamism of supply chains, companies often do not know what actors operate in their supply chains beyond direct suppliers. LÄS MER

  4. 3. Active flow control of the turbulent boundary layer over a NACA4412 wing profile for skin friction drag reduction

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Giacomo Semprini Cesari; [2023]
    Nyckelord :Active flow control; drag reduction; numerical simulations; turbulent boundary layer; wings;

    Sammanfattning : In the context of building a framework for active flow control of turbulent boundary layers in wings, a set of large-eddy simulation (LES) are implemented in OpenFOAM. The flow around a NACA4412 wing profile is simulated at 5° angle of attack and Re_c = 400˙000. LÄS MER

  5. 4. Generating Synthetic CT Images Using Diffusion Models

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Salih Saleh; [2023]
    Nyckelord :Machine learning; artificial intelligence; generative models; diffusion models; MRI; CT; synthetic CT; radiation therapy;

    Sammanfattning : Magnetic resonance (MR) images together with computed tomography (CT) images are used in many medical practices, such as radiation therapy. To capture those images, patients have to undergo two separate scans: one for the MR image, which involves using strong magnetic fields, and one for the CT image which involves using radiation (x-rays).

  7. 5. Uncertainties in the use of synthetic CT (sCT) for daily online adaptive radiotherapy for lung cancer

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Johansson Vivika; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background and purpose: Cone Beam Computed Tomography (CBCT) based online adaptive radiotherapy (oART) has been clinically implemented for several anatomical sites worldwide. However, random and abrupt anatomical changes with large density alterations can occur in lung patients, leading to uncertainties with synthetic computed tomography (sCT) and dose calculation. LÄS MER
