  1. 11. Microstructures and Compressive Strength of Lake Ice in Sweden A structural Documentation and Compressive Strength Analysis of Lake Ice Cores from Uppsala, using the SonReb Method

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Julia Ladefoged; [2023-08-18]
    Keywords : ;

    Abstract : Lake ice have been utilized by humans through centuries, as transportation routes and recreational activities to name a few (Sharma et al., 2019). Despite our frequent usage of lake ice there is a lack of extensive knowledge of it. READ MORE

  3. 12. Invasive plant species in southwest Sweden: Evaluation methods of removal by empirical study and literature review

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Carl-Johan Dekker; [2023-08-07]
    Keywords : Invasive alien species; management; nature conservation; biodiversity;

    Abstract : Invasive alien species (IAS), are one of the five biggest threats to biodiversity worldwide. An instrument for biodiversity protection in Sweden is the establishment and management of nature reserves. The goal of nature reserves is to protect valuable nature and rare species to preserve biodiversity. READ MORE

  4. 13. A personalized quasi-passive ankleexoskeleton using human-in-the loop optimization approaches

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ho Ming Kong; [2023]
    Keywords : ;

    Abstract : Passive ankle exoskeletons have been proven to successfully decrease muscle demand for walking. The movement of the user’s ankle drives a mechanical clutch and spring, which eventually stores and returns mechanical energy to the user. READ MORE

  5. 14. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ahsan Ali; [2023]
    Keywords : High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

    Abstract : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

  6. 15. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Simon Dahl; [2023]
    Keywords : Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

    Abstract : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. READ MORE
