  1. 1. Evaluation of The Viral Reduction Potential using Ultrafiltration Membranes in the Drinking Water Treatment Process at Norrvatten

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Emma Eriksson; [2023]
    Nyckelord :Microbiological barrier; Ultrafiltration; NanoCeram filter; Drinking Water; Raw Water; Mikrobiologisk barriär; Ultrafiltering; NanoCeram filter; Dricksvatten; Råvatten;

    Sammanfattning : En pilotanläggning för ultrafiltering testas nu i Norrvattens reningsprocess för att undersöka ifall den kan användas som en tredje mikrobiologisk barriär i reningsprocessen. Målet med detta projekt är att testa membranets kapacitet att filtrera bort viruspartiklar men även membranet generella reduktionsförmåga för andra mikrobiologiska och kemiska kontamineringar.

  4. 3. Evaluation of Tree Planting using Computer Vision models YOLO and U-Net

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Sofie Liszka; [2023]
    Nyckelord :Unet; YOLOv8; Autonomous tree planting;

    Sammanfattning : Efficient and environmentally responsible tree planting is crucial to sustainable land management. Tree planting processes involve significant machinery and labor, impacting efficiency and ecosystem health. In response, Södra Skogsägarna introduced the BraSatt initiative to develop an autonomous planting vehicle called E-Beaver. LÄS MER

  5. 4. Operando detection of Li-plating by online gas analysis and acoustic emission monitoring

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Inti Espinoza Ramos; [2023]
    Nyckelord :Li-ion batteries; graphite; solid electrolyte interphase; lithium plating; online gas analysis; operando acoustic emission monitoring;

    Sammanfattning : Lithium ion batteries (LIBs) are widely used for storing and converting chemical energy into electrical energy. During battery operation, lithium ions move between electrode materials, enabling energy storage. However, aging mechanisms like lithium plating can negatively impact battery performance and lifetime. LÄS MER
