  1. 16. FE-Modelling of Composite Girder tests

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Holger Berggren; Bergstedt Ola; [2024]
    Nyckelord :shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Sammanfattning : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. LÄS MER

  3. 17. Validering av KFX för vätgasjetflammor som träffar ytor

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Jonathan Nilsson; [2024]
    Nyckelord :Kameleon FireEX; KFX; CFD; Hydrogen Jetfire; Technology and Engineering;

    Sammanfattning : Regarding climate change and the future need för renewable energy, hydrogen is considered to be an important component in energy storage systems. However, the use of hydrogen is fraught with risk due to its chemical properties. This thesis deals with the problem of modelling heat transfer from hydrogen jet flames hitting surfaces. LÄS MER

  4. 18. Investigating the dynamics between the developing Nordic hydrogen market and the electricity system under uncertainty

    Master-uppsats, KTH/Energiteknik

    Författare :Timon Renzelmann; [2024]
    Nyckelord :energy modelling; energy storage; global sensitivity analysis; hydrogen; Method of Morris; Nordics; OSeMOSYS; uncertainty analysis; energimodellering; energilagring; global känslighetsanalys; vätgas; Morris-metoden; Nordiska länder; OSeMOSYS; osäkerhetsanalys;

    Sammanfattning : The potential of hydrogen as a clean energy carrier is hotly debated, but it promises to significantly contribute to a sustainable energy future. Hydrogen can replace fossil fuels in carbon-intensive industries, heavy transport and aviation, and support a renewable energysystem by acting as energy storage to balance intermittent supply.

  5. 19. MODELLING THE SMOLT PRODUCTIVITY OF BROWN TROUT (SALMO TRUTTA) IN HAGA Å

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Lukas Almgren; [2023-10-30]
    Nyckelord :Brown trout; Salmo trutta; Trout habitat score; THS; Haga å; electro-fishing survey;

    Sammanfattning : The brown trout (Salmo trutta) is a facultatively anadromous species, some individuals migrate from the rearing environment in the rivers to the sea while other individuals stay in fresh water. To determine the suitability of a stream for juvenile trout the organization SGBALANST has developed what is called the "Trout habitat score" (THS) model. LÄS MER

  7. 20. Audio Anomaly Detection in Cars

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Asma Hussein; [2023-09-11]
    Nyckelord :Audio Anomaly detection; Outlier detection; Machine learning; Mel Frequency; Chroma;

    Sammanfattning : Audio anomaly detection in the context of car driving is a crucial task for ensuring vehicle safety and identifying potential faults. This paper aims to investigate and compare different methods for unsupervised audio anomaly detection using a data set consisting of recorded audio data from fault injections and normal "no fault" driving.
