  1. 1. The visibility of stellar transients in the Galactic Centre

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Astrofysik

    Author : Jonathan Ström; [2024]
    Keywords : Physics and Astronomy;

    Abstract : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. READ MORE

  3. 2. Self-Supervised Learning for Tabular Data: Analysing VIME and introducing Mix Encoder

    University essay from Lunds universitet/Fysiska institutionen

    Author : Max Svensson; [2024]
    Keywords : Machine Learning; Self-supervised learning; AI; Physics; Medicine; Physics and Astronomy;

    Abstract : We introduce Mix Encoder, a novel self-supervised learning framework for deep tabular data models based on Mixup [1]. Mix Encoder uses linear interpolations of samples with associated pretext tasks to form useful pre-trained representations. READ MORE

  4. 3. ¿Quién dió la orden? Mediations for social change, affects and digital media

    University essay from Uppsala universitet/Institutionen för informatik och media

    Abstract : In 2019,  Movice and CT created a mural that depicts faces of  high-ranking military officers who were in command when more than 6.000 civilians were killed by soldiers and were presented as guerilla members. READ MORE

  5. 4. 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. 5. 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
