  1. 1. Wind Turbine Recovery Forecasting using Survival Analysis

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Anton Palets; [2023]
    Nyckelord :Survival analysis; Recovery Forecast; Wind Turbine; Availability Forecast; AFT model; Aalen s model; Cox regression; Cox Proportional Hazards; Variation Processes; Mathematics and Statistics;

    Sammanfattning : The goal of this thesis is to present a methodology for predicting time until recovery of failed wind turbines. The necessity is motivated by the potential for more accurate wind energy export forecasts. The current approach rests entirely on having an expert examine the turbine and produce a time estimate.

  3. 2. Optimal Discharge from a Hydropower Plant for Fish Reproduction: An Aquatic Habitat Model

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Hugo Lindbäck; [2023]
    Nyckelord :Weighted Usable Area WUA ; minimitappning; HEC-RAS; salmo; Helge å; den nationella planen för omprövning av vattenkraft NAP ; Technology and Engineering;

    Sammanfattning : Hydropower is the dominant source of electricity in Sweden, constituting 45% of the national supply. While pivotal for decarbonization and climate goals, its environmental impact on freshwater biodiversity is concerning. LÄS MER

  4. 3. Analysis of free-riding behaviour using instrumented bicycles

    Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Jonathan Johansson; [2023]
    Nyckelord :Data collection; instrumented bicycle; free-riding; conventional bicycle; electric bicycle; naturalistic data;

    Sammanfattning : The use of bicycle as a transportation mode has increased in popularity during the last four decades. The reasons that could explain why the use of bicycles have increased in popularity are many. LÄS MER

  5. 4. Conditioned 3D-printed polyamides for structural optimization : Establishing the material data to advance in AM utilization

    Master-uppsats, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Philip Olsson; [2022]
    Nyckelord :Additive manufacturing; selective laser sintering; multi jet fusion; moisture; temperature;

    Sammanfattning : Polyamides are commonly used in additive manufacturing for final part production, but the material performance can be affected by environmental conditions. The purpose of this project was to evaluate the effects of moisture and temperature on 3D printed polyamides and how structural optimization can benefit from condition-specific data. LÄS MER

  7. 5. Methodology for Obtaining S-N Curves using Fatigue Testing and Static FEA

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Filip Anderfelt; David Äse; [2022]
    Nyckelord :Fatigue; Testing; Fatigue Testing; Test rig; Pneumatic; FEA; Weld; Steel; Fillet Weld; S-N curve;

    Sammanfattning : The use of recommended S-N curves, presented in current literature, to analyse and determine the fatigue life of a part is common practice in, inter alia, the construction industry.However, the recommended S-N curves are generally created for larger components used in mainly the construction industry.
