  1. 1. Identification of Fibers in Micro-CT Images of Paperboard Using Deep Learning

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :David Rydgård; [2023]
    Nyckelord :Fiber networks; Paperboard mechanics; Deep learning; Tomography; Image analysis; Technology and Engineering;

    Sammanfattning : This master thesis project explores the possibility of using deep learning to segment individual fibers in three-dimensional tomography images of paperboard fiber networks. We test a method which has previously been used to segment fibers in images of glass fiber reinforced polymers. LÄS MER

  3. 2. A coupling method using CFD, radiative models and a surface model to simulate the micro-climate

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Joseph Vernier; [2023]
    Nyckelord :Computational Fluid Dynamics; Fluid Mechanics; Numerics; Micro-climate modeling; Radiation; Crop modeling; Photovoltaic panels;

    Sammanfattning : The increasing demand for energy, depletion of fossil fuels, rising global warming, and greenhouse gas emissions have stimulated the need for widespread development and adoption of renewable energy sources (RES) worldwide. Among these sources, solar energy has emerged as a major contender to meet the growing demand. LÄS MER

  4. 3. Tomography-based Micromechanical Analysis of Novel Composite Material

    Master-uppsats, KTH/Hållfasthetslära

    Nyckelord :paper mechanics; micro mechanics; numerical analysis; tomography; foam forming; density profile; pappersmekanik; mikromekanik; numerisk analys; tomografi; skumformning; densitetsprofil;

    Sammanfattning : This study explores the performance of porous Paptic paper materials composed of a mixture of softwood and lyocell fibers. The investigation involves laboratory experiments and numerical simulations to analyse the impact of various parameters on the paper's characteristics. LÄS MER

  5. 4. Power dynamics and order formation in mobile MOBA games : a Foucauldian analysis of "Honor of Kings"

    Master-uppsats, Lunds universitet/Medie- och kommunikationsvetenskap; Lunds universitet/Institutionen för kommunikation och medier

    Författare :Shuaijun Zhang; [2023]
    Nyckelord :Social Sciences;

    Sammanfattning : Video games can be seen as a media that immerses players. The formation of a good game order is an important guarantee for players to engage in electronic games. This paper selects the most popular mobile MOBA game in China, "Honor of Kings," as the research object to analyze the formation process of the game order. LÄS MER

  7. 5. The influence of post-buckling damage on the tensile properties of single wood pulp fibers

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Raphael Andreolli; [2021]
    Nyckelord :Solid Mechanics; single fiber testing; wood pulp fibers; post-buckling damage; experiments; development of testing methods; tensile properties; tensile stiffness; tensile strength; Hållfasthetslära; enskild fiber testning; pappersmassa fiber; skada efter knäckning; experiment; utveckling av testutrustning; dragegenskaper; dragstyvhet; draghållfasthet;

    Sammanfattning : The rapid growth of plastic waste from food packaging around the world demands renewable substitutes, such as natural fibers and biocomposites. Wood fibers are natural fibers extracted from trees and are commonly used in packaging. LÄS MER
