  1. 1. Insights Into Wind Profile Characteristics in the Arctic Marine Boundary Layer

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Charlotte Sophie Gausa; [2024]
    Nyckelord :Arctic; wind profile power law; MOST; boundary layer; low level jets; sea ice; vindprofil; Arktis; gränsskikt; vindenergi; låghöjdsvindar; havsis;

    Sammanfattning : The atmospheric boundary layer in the Arctic is essential for the understanding of climate change and improving regional weather prediction. The aim of this study is to investigate to which degree wind speed profiles retrieved in the Arctic agree with well known wind profile concepts and understand which local impact factors influence the wind speed profile.

  3. 2. Nutrient flow on agroforestry farms in the province of Son La in northwest Vietnam

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Vindenergi

    Författare :Tula Strotz; [2023]
    Nyckelord :Agroforestry; contouring grass rows; Guinea grass; nutrient losses; Vietnam; Gräsbarriärer; Höglandsodling; näringsförlust; Träjordbruk; Vietnam;

    Sammanfattning : The population in the high mountains of the northwest provinces of Vietnam belongs to the poorest population in the country. Among the reasons behind this are the high frequency of minority groups in the region and the infertile soils of the steep slopes. LÄS MER

  4. 3. Establishing the Interlinkages between Sustainable Development Goals (SDGs) and Energy projects

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

    Författare :Jithin Jomy; Siddharth Pandit; [2023]
    Nyckelord :Sustainable Development Goals PROject Performance Evaluation and Learning SDGs-PROPEL ; Sustainable Development Goals SDGs ; Energy Projects; Sustainability Assessment; Synergies and trade-offs; Environmental; Social Governance ESG reporting; Mål för hållbar utveckling PROject Performance Evaluation and Learning SDGs-PROPEL ; Mål för hållbar utveckling SDG ; Energiprojekt; Hållbarhetsbedömning; Synergier och avvägningar; miljö-; social- och styrelserapportering ESG ;

    Sammanfattning : The pursuit of Sustainable Development Goals (SDGs) requires a transformative approach to energy systems, focusing on cleaner, reliable, and affordable energy services. This pursuit of achieving the SDG 7 goal of universal access to affordable and clean energy, can have numerous positive and negative implications on all other SDGs and their targets. LÄS MER

  5. 4. Microgrid in George Washington, Cuba

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

    Författare :Mimmi Fröjdh; Sofia Sjöberg; [2023]
    Nyckelord :Cuba; microgrid; energy systems modelling; renewable energy; optimization; Kuba; microgrid; energisystemmodellering; förnybar energi; optimering;

    Sammanfattning : Cuba has vast natural resources for domestic renewable energy generation, but their energy mix is heavily dominated by fossil fuels. This contributes to a high dependence on expensive oil imports and has led to significant generation shortfalls, which in turn has resulted in extensive power outages and serious fuel crises.

  7. 5. Weight Optimization of Vertical-Axis Wind Turbine Blades constructed in Swedish Fossil Free Steel : With respect to fatigue life time

    Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Johannes Hall; Albin Larsson; [2023]
    Nyckelord :VAWT; Wind Turbine Blade; SSAB; Fossil-Free; Weight Optimization; Topology Optimization; Sizing Optimization; NACA 0018; STRENX 1300; Abaqus; Tosca Structure; VAWT; Vindturbinblad; SSAB; Fossilfritt; Viktoptimering; Topologioptimering; Size-Optimering; NACA 0018; STRENX 1300; Abaqus; Tosca Structure;

    Sammanfattning : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. LÄS MER
