  1. 1. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Lina Näslund; Gabriella Petersson; [2023]
    Nyckelord :Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

    Sammanfattning : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. LÄS MER

  3. 2. Investigation of the Microstructure of Plastically Deformed Cemented Carbide

    Master-uppsats, KTH/Materialvetenskap

    Författare :Felicia Larsson; [2023]
    Nyckelord :;

    Sammanfattning : During machining operation, cemented carbide tools are exposed to high loads and temperatures, which eventually leads to plastic deformation of the tool material. The aim of this work was to investigate if the microstructures of creep deformed micro grain cemented carbides can be linked to alloying elements and mechanical properties. LÄS MER

  4. 3. Micro Crops & The Iterative Wave

    Master-uppsats, Göteborgs universitet/HDK-Valand - Högskolan för konst och design

    Författare :Brianna Butler; Andrea Bindar; [2023]
    Nyckelord :Design; Aesthetic objects; system; Microplastics; Wicked problems; MFA in Design with specialisation in Embedded Design;

    Sammanfattning : The current approach to facilitation has numerous benefits but lacks sufficient challenge in raising awareness about wicked problems. This paper discusses the authors’ master thesis project, conducted in collaboration with the organizational context of a plastic-free store in the Gothenburg area. LÄS MER

  5. 4. Design and Construction of an Autonomous Sentry Turret Utilising Computer Vision

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

    Författare :Carl Bermhed; Jacob Holst; [2023]
    Nyckelord :Mechatronics; Arduino; Computer Vision; Stepper Motor; Airsoft; Haar Cascade; Mekatronik; Arduino; Datorseende; Stegmotor; Airsoft; Haar Cascade;

    Sammanfattning : The design and manufacture of a sentry gun turret capable of accurately and rapidly tracking and shooting moving targets was a challenging task that required delving into various engineering disciplines. This bachelor's thesis explores this challenge by presenting the process of construction, as well as the performance results of a turret created using a combination of 3D printing, laser cutting, and metal workshop manufacturing.
