  1. 1. Hunting Hotspots - A framework to assess the effectiveness of using environmentally extended input-output models as a method to identify CO2-eq hotspots in the upstream supply chain of a company

    University essay from Lunds universitet/LUCSUS

    Author : Elisa Anni Bauer; [2023]
    Keywords : GHG emissions; Effectiveness; Hotspot analysis; Environmentally Extended Input-Output; Sustainability Science; Social Sciences;

    Abstract : Industry’s indirect upstream greenhouse gas (GHG) emissions contribute significantly to climate change. To identify and reduce them, some companies conduct a hotspot analysis using an environmentally extended input-output (EEIO) model (often utilizing EXIOBASE database). READ MORE

  3. 2. Life cycle assessment of metal laser powder bed fusion : A deep dive into the significance of system boundary expansion and improvement potential

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Christian Rotter; Erik Fagerberg; [2023]
    Keywords : additive manufacturing; life cycle assessment; powder bed fusion; system boundaries; metal laser powder bed fusion; environmental impact; global warming potential;

    Abstract : Metal additive manufacturing (MAM) is a manufacturing technology experiencing a rapid expansion rate. Metal laser powder bed fusion (ML-PBF) is among the most popular techniques in this field. The environmental implications of it are often discussed in literature and compared to conventional manufacturing. READ MORE

  4. 3. Self-learning for 3D segmentation of medical images from single and few-slice annotation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Côme Lassarat; [2023]
    Keywords : Self-supervised Learning; Segmentation; Medical images; Självövervakad inlärning; segmentering; medicinska bilder;

    Abstract : Training deep-learning networks to segment a particular region of interest (ROI) in 3D medical acquisitions (also called volumes) usually requires annotating a lot of data upstream because of the predominant fully supervised nature of the existing stateof-the-art models. To alleviate this annotation burden for medical experts and the associated cost, leveraging self-learning models, whose strength lies in their ability to be trained with unlabeled data, is a natural and straightforward approach.

  5. 4. Vattenföroreningars påverkan på biologisk mångfald och abundans hos akvatiska evertebrater : en studie i södra Sverige

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Sandra Wiig; Sara Åsberg; [2023]
    Keywords : Abundans; akvatiska evertebrater; biodiversitet; reningsverk; vattenkvalitet;

    Abstract : Föroreningar i landskapets vatten kan spridas genom många olika faktorer, exempelvis via reningsverk, skogsbruk och jordbruk. De organismer som lever i vattenmiljöer kan vara mycket känsliga för de föroreningar som släpps ut, vilket kan leda till allvarliga konsekvenser som förlust av biologisk mångfald och andra förändringar inom dessa samhällen.

  6. 5. Life Cycle Assessment as a decision-making tool within vaccine manufacturing – Potential and Limitations

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Simon Deklerck; [2023]
    Keywords : Decision-making; energy intensive industries; Life Cycle Assessment; Life Cycle Inventory; pharmaceutical; Product Footprint Calculator; value chain; vaccine manufacturing;

    Abstract : Life Cycle Assessment (LCA) is a widely used method for evaluating the environmental impacts of a product throughout its entire life cycle. As a decision-making tool, LCA allows decision-makers to identify the environmental hotspots in a product or process, and to explore opportunities for improvement. READ MORE
