  1. 11. CFD Analyses for Wind Load AssessmentCFD Analyses for Wind Load Assessment : Wind-induced vibrations in the Bomarsunds Bridge hangers

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Fatiha El Azrak; [2023]
    Nyckelord :;

    Sammanfattning : The trend in recent years of building longer and slender bridge components has introduced new challenges to ensure their stability and strength. This master thesis focuses on the effects of wind-induced vibrations in the context of long, slender arch bridge components, particularly the recently constructed Bomarsunds Bridge in Åland, Finland.

  3. 12. Accelerated Testing of the End-plate Assembly of a Redox Flow Battery

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

    Författare :Saksham Jindal; [2022]
    Nyckelord :Energy Storage; Flow Batteries; Accelerated Testing; Contact Resistance; Endplate Assembly; Leak Rate; Stack Design; Energilagring; flödesbatterier; accelererad provning; kontaktmotstånd; montering av ändplattor; läckagehastighet; utformning av staplar.;

    Sammanfattning : As the world transitions to intermittent renewable energy sources like solar and wind, the need for long-duration energy storage technologies is becoming more and more prominent. In this regard, flow batteries are seen as a promising solution, owing to their inherent advantages like decoupling of power and energy, extremely high cycle life and negligible self-discharge.

  4. 13. U - Net Based Crack Detection in Road and Railroad Tunnels Using Data Acquired by Mobile Device

    Master-uppsats, KTH/Geoinformatik

    Författare :Kepan Gao; [2022]
    Nyckelord :U-Net; deep learning; tunnel monitoring; structural health monitoring; crack detection; mobile mapping system;

    Sammanfattning : Infrastructures like bridges and tunnels are significant for the economy and growth of countries, however, the risk of failure increases as they getting aged. Therefore, a systematic monitoring scheme is necessary to check the integrity regularly. LÄS MER

  5. 14. Micro- / Meso- Scale Dielectric Strength Testing of Fibre Composites

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Johannes Fernberg; [2022]
    Nyckelord :Dielectric strength; composite; GFRP; glassfibre; composite microstructure; FEA; electric breakdown; single fibre;

    Sammanfattning : Glass fibre composites are common materials used in high voltage applications as insulating materials that provide good structural integrity. The aim of this thesis is to develop a method of studying the failure in such materials by measuring the dielectric strength on micro- and meso- scale samples, consisting of single fibre filaments and fibre bundles respectively embedded in epoxy resin.

  7. 15. Influence of Humidity Over the Properties of Wood Fiber-based Biocomposites

    Kandidat-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Arvid Hedin; Anna Kudinova; Linnea Masso; [2022]
    Nyckelord :Wood Polymer Composite; WPC; Relative Humidity; RH; Tensile Testing; Polypropene; FibraQ; Wood Fiber; Surface Treatment; Mechanical Properties;

    Sammanfattning : The project aims to develop a methodology to study the variation in properties of wood polymer composites (WPC’s) with/without surface treatment at different humidity conditions. The project aims to investigate the behavior of biocomposites at 50%, 80%and 100% relative humidity (RH). LÄS MER
