  1. 1. Effects of natural aging and low strain-rate on mechanical properties of aluminium alloy sheets used in automotive industry

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Amirhossein Gholami; Ali Abedisamarin; [2024]
    Nyckelord :Ageing. AA6014. AA6016;

    Sammanfattning : These days, lightweight materials such as aluminum alloy sheets, especiallythose in the AA6xxx series, are in high demand for use inthe automotive industry. During natural aging, the properties of aluminummay undergo significant changes due to the diffusion of atomswithin the crystal structure, impacting the strength and formabilityof aluminum sheets.

  3. 2. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Fredrik Malmström; [2024]
    Nyckelord :;

    Sammanfattning : The thesis proposes to model the flow of gases in a room by solving the incompressible Navier-Stokes equations in three dimensions. The transportationof scalars such as temperature and concentration of CO2 is modeled by solving the advection-diffusion equation, and the effects of temperature on thevelocity is accounted for by employing the Boussinesq approximation.

  4. 3. Powering Sustainable Development with SMRs - A qualitative study examining the potential effects of Small Modular Reactor deployment in Southern Sweden

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Alixander Kanaan; Marcus Magnusson; [2023-07-19]
    Nyckelord :Small modular reactors; Sustainability; Eco-Innovation;

    Sammanfattning : Europe has been immensely impacted by the recent turmoil in the continent and an energy crisis has emerged. Energy prices have soared over a period of two years and the price of energy is still at elevated levels throughout Europe and a high dependency on fossil fuels for energy production has become inevitable.

  5. 4. Preprocessing for intravoxel incoherent motion analysis in the brain - Signal drift correction

    Master-uppsats,

    Författare :Amina Warsame; [2023-04-17]
    Nyckelord :Medical physics; Diffusion magnetic resonance imaging; dMRI; Intravoxel incoherent motion; IVIM;

    Sammanfattning : Diffusion magnetic resonance imaging (dMRI) is a diagnostic imaging technique that is sensitized to the movement of water molecules in tissues. Intravoxel incoherent motion (IVIM) analysis can be used to estimate blood flow in capillaries from weakly diffusion-weighted data. LÄS MER

  7. 5. Framgångsrik implementering av ny teknik och AI : En kvalitativ undersökning av svenska myndigheters effektiviseringsarbeten med chattbots i kundtjänsten

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Maja Markiewicz; [2023]
    Nyckelord :Chatbot; Socioteknisk systemdesign; Innovationer; Implementering; Organisatorisk tröghet; Förändringsledning;

    Sammanfattning : The following thesis investigates how Transportstyrelsen, a Swedish authority, can use chatbots in their customer service to increase effectivity, save resources and be more available to their customers. Therefore, this report aims to map the effects a chatbot-implementation would have on Transportstyrelsen’s business and what technical and organisational factors that contribute to a successful implementation of the chatbot.
