  1. 1. Carbonation of concrete : Evaluation of CO2 uptake of Benders Sverige AB concrete products and landfills

    Kandidat-uppsats,

    Författare :Juliana Kessler; Joakim Melander; Emil Tronde; Gustav Åderman; Erik Österlund; [2021]
    Nyckelord :;

    Sammanfattning : The cement industry accounts for 5-7% of the global emissions of carbon dioxide, where CO2 is mainly emitted during the calcination process. However, CO2 is also absorbed by all concrete products during their lifetime through the process of carbonation. LÄS MER

  5. 4. Study of Bandwidth Partitioning for Co-executing GPU Kernels

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Erik Melander; [2017]
    Nyckelord :;

    Sammanfattning : Co-executing GPU kernels on a partitioned GPU has been shown to improve utilization efficiency of poorly scaling tasks. While kernels can be executed in parallel, data transfers to the GPU are serial which can negatively impact parallelism and predictability of the kernels. LÄS MER

  7. 5. The effect of charged groups on the beatability of pulp fibres

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Erik Melander; [2011]
    Nyckelord :Kraft pulp; softwood; carboxymethylation; swelling; PFI beating; refining; beatability; charged groups;

    Sammanfattning : The purpose of this bachelor thesis was to investigate how charged groups within the pulp fibre affect the beatability and the strength of the papers. To obtain different levels of charges on the pulp it was carboxymethylated. The different pulp samples were beaten to different degrees to investigate how charges interact with the beating. LÄS MER
