  1. 1. Automatised detection of sources for power curve deviations of horizontal axis wind turbines

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Marius Walter; [2022]
    Nyckelord :Wind Power; Automation; Power Curve; SCADA; Predictive Maintenance;

    Sammanfattning : To face climate change and transform the electricity supply to an environmentally friendly generation, wind plays an important role. Due to a yearly increase in installed wind power turbines, in the European Union, the need for maintenance increases as well. LÄS MER

  3. 2. Idealised remediation scenario in two small-scale intersecting fractures

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Agnes Zúniga Ekenberg; [2022]
    Nyckelord :;

    Sammanfattning : Analysis of mass transport in rock fractures has become increasingly important in underground storage of radioactive materials and remediation of polluted groundwater in fractured rock aquifers. Permeability of rock mass is regulated by present rock fractures, where flow is mainly through the fracture networks. LÄS MER

  4. 3. Mechanical properties of WE43 : Finding optimized process parameters using PBF-LB for enhanced properties of the magnesium alloy

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Fanny Saarela; Fanny Sandblad; [2022]
    Nyckelord :biomedical engineering; materials science; additive manufacturing; powder bed fusion laser beam; PBF-LB; magnesium; magnesium alloys; WE43; mechanical properties; scan strategy; layer rotation; build direction; build orientation;

    Sammanfattning : When skeletal fractures are too extensive for fixation with plates and screws, autografts are the most used technique for treating this. Within the biomedical field the interest in biodegradable implants made from additive manufacturing have increased. Magnesium alloys has also gained interest because of its favorable mechanical properties.. LÄS MER

  5. 4. Mescape - A probabilistic mesoscopic model for fire evacuation in large gatherings

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Lorenzo Contini; [2022]
    Nyckelord :Human behaviour; crowd evacuation; mesoscopic modelling; hydraulic model; large gatherings; fire safety; performance-based design; quantitative risk assessment; consequence analysis; uncertainty analysis; probabilistic modelling; Technology and Engineering;

    Sammanfattning : This study presents a mesoscopic model that predicts pedestrian evacuation in large gatherings with probabilistic methods. The model is based on a coarse network representation of buildings, where occupants are treated at a different scale according to their location. LÄS MER

  7. 5. Material Characterization and Blade Impact Simulation

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Gustaf Bodare; [2022]
    Nyckelord :Strain rate dependency; Split-Hopkinson pressure bar; Digital image correlation; LS-DYNA; FEM; SPG;

    Sammanfattning : Blades used on brushcutters and lawn mowers are subjected to a wide variety of working conditions. Besides continuous loads from cutting grass, the blades are also subjected to accidental impacts of branches, stones and structures. LÄS MER
