  1. 1. 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.

  3. 2. 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.

  4. 3. Flood mitigation at catchment scale: assessing the effectiveness of constructed wetlands

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Elin Ekström; [2023]
    Keywords : Nature-based solutions; wetlands; catchment; performance indicators; flood management; hydrological modeling; SWAT; Naturbaserade lösningar; våtmarker; avrinningsområde; nyckelindikatorer; översvämningshantering; hydrologisk modellering; SWAT;

    Abstract : Considering the potential for natural wetlands to store and retain water in the landscape,restored and constructed wetlands are increasingly implemented as Nature‐BasedSolutions (NBS) to mitigate downstream flooding. However, there is a frequent lack ofknowledge of the performance of NBS, and particularly wetlands, and how to best selectperformance indicators to measure their effectiveness. READ MORE

  5. 4. Comprehensive Venus boundaries model : Empirical dependency of boundaries on the upstream conditions

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

    Author : Umberto Rollero; [2023]
    Keywords : Bow shock; Ion Composition Boundary; Venus; Upstream conditions; Solar wind.; Bow shock; Bogshock; Ion Composition Boundary; Venus; Uppströmsförhållanden; Solvind.;

    Abstract : Since Venus is an unmagnetized planet, it doesn’t interact with the solar wind in the same way as planets with an intrinsic magnetic field do. Due to its conductive ionosphere, however, it still possesses an induced magnetosphere. READ MORE

  6. 5. The connection between the bow shock at Mercury and the interplanetary magnetic field

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

    Author : Erik Sellberg; [2023]
    Keywords : Mercury bow shock; Bow shock - interplanetary magnetic field interaction; MESSENGER; Merkurius bogchock; Växelverkan bogchock interplanetära magnetfältet; MESSENGER;

    Abstract : As the solar wind reaches Mercury it interacts with the planet’s magnetic field slowing down, forming a bow shock in front of the planet and diverting the flow around it. Along with the solar wind comes the interplanetary magnetic field, an extension of the sun’s magnetic field. READ MORE
