  1. 16. Life Cycle Assessment of a small scale, solar driven HVR water purification system

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

    Författare :Sharang Kolathur; [2022]
    Nyckelord :life cycle assessment; air gap membrane distillation; solar energy; levelized cost; grid operated system; livscykelanalys; luftgapmembrandestillation; solenergi; utjämnade kostnader; nätdrivet system;

    Sammanfattning : Water purification systems have made access to drinking water easier by treating water sources which previously could not be used for drinking. Such systems however require energy and materials to build and operate which means they have environmental impacts. LÄS MER

  3. 17. Tuning of the ESS Drift Tube Linac using Machine Learning

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

    Författare :Johan Lundquist; [2022]
    Nyckelord :Accelerator; drift tube linac; machine learning; neural network; ESS; linac; tuning; proton; longitudinal dynamics; beam physics; Physics and Astronomy;

    Sammanfattning : The European Spallation Source, currently under construction in Lund, Sweden, will be the world's brightest neutron source. It is driven by a linear accelerator designed to accelerate a beam of protons with 62.5 mA, 2.86 ms long pulses, working at 14 Hz. LÄS MER

  4. 18. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    Master-uppsats, KTH/Materialvetenskap

    Författare :Hagen Christian Hagens; [2022]
    Nyckelord :Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Sammanfattning : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. LÄS MER

  5. 19. Evaluation of the impact of reduced scan field-of-view (SFOV) on CT radiation dose and image quality in a chest CT – a phantom study

    Magister-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Fleury Ndongozi; [2022]
    Nyckelord :;

    Sammanfattning : Background: Technical development of image detectors and dose-reduction techniques in computed tomography (CT) have contributed to reduce radiation dose for patient and staff. The scan field of view (SFOV) generally affects the radiation dose the patient will beexposed. LÄS MER

  7. 20. Co-Simulation Development for Improved Cavitation Predictions in Oil-Hydraulics Systems : An investigation into the cavitating flow behavior of repetitive water hammers.

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Thisal Mandula Sugathapala; Twan Bakker; Rahul Gudur Suresh; Aryan Delir; [2022]
    Nyckelord :co-simulation; water hammer; cavitation;

    Sammanfattning : Numerical modeling of cavitation using computational software is a highly pursued topic of research due to its impact in different industrial sectors. While some industrial applications such as wastewater treatment and mineral processing are known to advantageously use this phenomena, it remains an unwanted process in others where it is known to induce vibration, reduce performance and cause structural damage.
