  1. 1. Design av fysiskt användargränssnitt till ett luftburet skördarverktyg

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Mohamed Mohamud; Kasper Olsson; [2023]
    Nyckelord :drönare; skördaraggregat; användargränssnitt; ergonomi; inmatning; konceptgenerering;

    Sammanfattning : Forest thinning involves the removal of some trees to benefit the other trees in the forest. When forestsare thinned, heavy machines are used that drive through the forest and affect the forest negatively. The company Airforestry is developing a new system that offers the possibility of thinning from the air using an electric drone. LÄS MER

  3. 2. Reliability Assessment of Passive ICS in an SMR as part of the PSA Analysis

    Master-uppsats, KTH/Fysik

    Författare :Graeme Trundle; [2023]
    Nyckelord :Passive system reliability; Probabilistic safety assessment; Reliability Methods of Passive Systems; Natural circulation; TRACE; RiskSpectrum; Passiv systemtillförlitlighet; Probabilistisk säkerhetsbedömning; Reliability Methods of Passive Systems; Naturlig cirkulation; TRACE; RiskSpectrum;

    Sammanfattning : Passive safety systems are increasingly being utilized in prospective nuclear power plant designs. Indeed, the use of safety systems driven by natural phenomena might be seen as an unmitigated virtue. LÄS MER

  4. 3. Identifying training needs for the implementation of Continuous Cover Forestry in Sweden

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Lydia Kruse; [2023]
    Nyckelord :Marteloscope; Thinning type; Conitnuous Cover Forestry; Frame tree; Human behaviour;

    Sammanfattning : In recent decades, continuous cover forestry (CCF) has been (re-)discovered as an important toolbox for promoting biodiversity, helping to deliver a range of ecosystem goods and services as well as to satisfy the needs of various stakeholders. CCF is based on ecological principles and one of its most important tenets is the abandonment of large-scale clearfelling. LÄS MER

  5. 4. Tour expansion in snow removal problem

    Kandidat-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Anna Tarasova; [2022]
    Nyckelord :Snow removal; link; node; graph; tree; degree of node; sweep; node task; link task; switching;

    Sammanfattning : The process of removing snow from the streets of cities in an optimal way can pose quite a challenge. In order to optimize the path of the snow removing vehicle, the city can be translated into a graph with nodes as crossings and links as roads. LÄS MER

  7. 5. Reindeer decrease soil carbon stocks and deplete labile soil carbon

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Josua Seitz; [2022]
    Nyckelord :Reindeer; SOC; soils; Finnland; 13C NMR;

    Sammanfattning : Reindeer have been shown to alter boreal ecosystems by changing the vegetation cover and influencing belowground processes. By providing nutrients for plants and by exerting trampling stress on the field layer vegetation, reindeer induce shifts in the vegetation where ground-lichen are being replaced by evergreen shrubs.
