  1. 11. Viscoelasticity of transparent wood-polymer biocomposites : Measuring the time-dependence of a delignified birch and poly(methyl methacrylate) composite’s mechanical properties, using digital image correlation

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Marine Jeanne Debouvry; [2023]
    Nyckelord :;

    Sammanfattning : The viscoelastic behavior of a delignified birch and poly(methyl methacrylate) (PMMA) composite was investigated, in an effort to learn more about the mechanical properties of transparent wood-polymer biocomposites. Tensile creep tests with constant load were performed for native wood, non-delignified, and delignified wood-polymer composites. LÄS MER

  3. 12. FPGA Accelerated Digital Image Correlation For Clamping Force Measurement

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :János Csanád Csuvarszki; [2023]
    Nyckelord :Digital image correlation; Field-programmable gate array; High-level synthesis;

    Sammanfattning : Digital image correlation is a contactless optical method used for displacement and strain measurement which has become increasingly popular in the field of experimental mechanics. A specialized use case for the algorithm is to measure the clamping force in bolted joints, a crucial metric when considering the longevity and reliability of the constructs. LÄS MER

  4. 13. Use of Digital Image Correlation for monitoring of concrete buttress dam failure model tests

    Master-uppsats, KTH/Betongbyggnad

    Författare :Jarl Jensen; Markus Leijström; [2022]
    Nyckelord :;

    Sammanfattning : The monitoring of dam structures is of great importance for the safety of the dam.A dam failure can cause disastrous consequences for people and infrastructure downstream.Dams are monitored by periodic inspections and monitoring systems. LÄS MER

  5. 14. Design and evaluation of a shock load resistant dynamic chain plate

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Daniel Olsson; [2022]
    Nyckelord :Dynamic; chain; shock load; Simulink; FEA; conveyor; wear; experimental; Nordic Quick Systems; chain plate; Simulation; FEM;

    Sammanfattning : Conveyor chains are often subject to repetitive shock loads during normal operations. This can cause accelerated wear in the chain leading to premature chain replacementor chain failure (Otoshi, 1997, p. 4). In this thesis a new approach for reducingshock load related wear in conveyor chains is proposed. LÄS MER

  7. 15. Artifact-Free Image Upscaling : An Evaluation of an Artifact-Free Color Interpolation Algorithm with Respect to Visual Quality

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Arvid Magnusson; Algot Sandahl; [2022]
    Nyckelord :;

    Sammanfattning : The vast number of different sizes and resolutions for digital displays today means that images regularly have to be upscaled or downscaled to fit the current screen. This scaling is almost always done using interpolation. LÄS MER
