  1. 1. Modelling and Optimal Control of a Variable Nozzle Turbine in an SI Engine for Maximum Performance

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Emil Fransson Brunberg; Karl Bolin; [2022]
    Nyckelord :Variable nozzle turbine; VNT; Variable geometry turbine; VGT; YOP; Collocation; Direct collocation; Optimal control; SI-engine; Engine control; Engine modelling;

    Sammanfattning : The ever increasing demands on today's engine performance and emissions control is forcing the automotive industry to make use of innovative solutions. One of these is to apply the technology of VNT turbos on commercial petrol vehicles. LÄS MER

  3. 2. Strengthening of non-composite bridges by Partial Composite Action

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Johan Tjernberg; [2022]
    Nyckelord :Composite action; Composite bridges; Partial shear connection; Partial Composite Action; Shear connectors; Coiled Spring Pins;

    Sammanfattning : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

  4. 3. Greenhouse gas emissions from compacted peat soil

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Antonia Hartmann; [2021]
    Nyckelord :carbon dioxide; compression index; Peatland agriculture; recompression index; sand addition; soil compaction;

    Sammanfattning : Cultivated peat soils are a main driver for CO2 and N2O emissions, while the gas fluxes are dependent on intrinsic soil properties and land use. Sand addition into peat soils might reduce greenhouse gas (GHG) emissions and enhance soil strength, and thus the ability to tolerate soil compaction. LÄS MER

  5. 4. Beach-cast fertilizers for cultivation of carrots and radishes on Swedish Gotland : The effect on crop size and nutrient composition

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Sofie Ögren; [2020]
    Nyckelord :Eutrophication; marine biofertilizer; beach-cast management; nutrient analysis; NMR;

    Sammanfattning : In the eutrophicated Baltic, algal blooms with toxin-producing algae and plant overgrowth is a large threat to the marine environment, humans and animals. The use of external nutrient inputs into agriculture, such as mineral fertilizers (NPK), is reaching the Baltic through runoff which causes a constant, linear nutrient flow from land to the sea, which is one of the main contributors to accelerated eutrophication.

  7. 5. Implementation of moisturedependent constitutive model for paperboard

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Venkata Venu Sai Phani Ram Babbepalli; [2020]
    Nyckelord :;

    Sammanfattning : There has been a considerable increase in the usage of paper products due to its sustainability in the product cycle. Many environmental and process variables can affect the mechanical behavior of paper from its making to finished products. LÄS MER
