  1. 16. Charting a Course for the Future: An Analysis of the Level of Climate-Security Integration in the EU’s Development Cooperation

    Master-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Roemer Goes; [2023]
    Nyckelord :climate-security; climate change; development cooperation; European Union; policy integration.; Law and Political Science;

    Sammanfattning : Climate-related security risks (CRSR) have risen on the foreign policy agenda of the European Union (EU). As climate change accelerates, its impacts exacerbate existing social, economic, and environmental challenges within and between communities and increase the likelihood of states experiencing humanitarian crises and conflict.

  3. 17. Dynamic Warning Signals and Time Lag Analysis for Seepage Prediction in Hydropower Dams : A Case Study of a Swedish Hydropower Plant

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datalogi

    Författare :Lovisa Olsson; Julia Hellström; [2023]
    Nyckelord :hydropower; dam safety; dam monitoring; seepage; prediction models; data-driven methods; artificial intelligence; AI;  linear regression; Support Vector Regression; SVR; Long Short-Term Memory; LSTM;

    Sammanfattning : Hydropower is an important energy source since it is fossil-free, renewable, and controllable. Characteristics that become especially important as the reliance on intermittent energy sources increases. However, the dams for the hydropower plants are also associated with large risks as a dam failure could have fatal consequences. LÄS MER

  4. 18. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

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

    Författare :Robert Liao; [2023]
    Nyckelord :;

    Sammanfattning : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

  5. 19. Apparent density for water atomized low-carbon steel powder

    Master-uppsats, KTH/Materialvetenskap

    Författare :Simon Lindström; [2023]
    Nyckelord :;

    Sammanfattning : Carbon content does not affect the apparent density for water atomized iron powder monotonically. At low carbon content, around 0.1 wt %, apparent density is higher than a similar powder with 0.3 wt % carbon. LÄS MER

  7. 20. An Investigation of How Hydrophobicity, Water, and Surface Topography Influence Macroscopic Particle Accumulation on Surfaces : A Case Study of Grass Accumulation on Robotic Lawn Mower

    Master-uppsats, Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Författare :Rasmus Brask-Nilsen; Petter Ydrestrand; [2023]
    Nyckelord :Macroscopic Particles; Accumulation; Hydrophobicity; Humidity; Topology; Adhesion; Experiments; Design of Experiments; Grass; Robotic Lawn Mower;

    Sammanfattning : This master's thesis project investigates the impact of hydrophobicity and topology on dry and wet macroscopic particle accumulation on surfaces. The report begins by outlining the challenges associated with this phenomenon and the existing theories and methods used to study it, including adhesion, surface engineering, the Lotus effect, and humidity.
