  1. 21. 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. 22. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Sanger Shinwari; [2023]
    Nyckelord :Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

    Sammanfattning : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. LÄS MER

  4. 23. Knowledge-Based Engineering Application For Fuselage Integration And Cabin Design

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Nikhil Bhargav; Vasanth Elangovan; [2023]
    Nyckelord :Commercial aircraft; Liquid Hydrogen; Cabin Design; LH2 Tank Integration; Sustainability; Knowledge Based Engineering; Tank Integration; Web Based Application;

    Sammanfattning : The pace of development in aviation technology is increasing, and there is a constantneed for new concepts to keep up. An innovative concept is desired to reach the netzero emission and sustainability target visualized in Flight path 2050. LÄS MER

  5. 24. Hur väl kan elever i årskurs 2 och 3 lyssna, förstå och minnas? En studie om sambandet mellan narrativ hörförståelse, nonordsrepetition och ordförståelse

    Magister-uppsats, Lunds universitet/Logopedi, foniatri och audiologi

    Författare :Elin Westerberg; Michelle Dzgoeva; [2023]
    Nyckelord :listening comprehension; narrative ability; nonword repetition; receptive vocabulary; word comprehension; Medicine and Health Sciences;

    Sammanfattning : Syfte: Syftet med studien var att belysa eventuella samband mellan narrativ hörförståelse, nonordsrepetition och ordförståelse hos elever i årskurs 2 och 3. Metod: Testning av nonordsrepetition, narrativ hörförståelse samt ordförståelse genomfördes med testmaterial Crosslinguistic Nonword Repetition Test, Lyssna, förstå och minnas samt deltest Ordförståelse från Diagnostisk screening för analys av läs- & skrivförmåga.

  7. 25. Possibilities and Challenges of City Planning using 3D Visualization : A systematic literature review on the possibilities of city visualization using 3D computer graphics and the utility of parametric design

    Kandidat-uppsats, Blekinge Tekniska Högskola

    Författare :Benjamin Lind Nilsson; [2023]
    Nyckelord :;

    Sammanfattning : There exist numerous previously conducted surveys, studies and written articles on the topic of 3D geo-visualization. The subject has been pursued increasingly for the last two decades. In the late 1960s, digital earth, the idea of a digital copy of the real world was first proposed. However, hardware capabilities were limited. LÄS MER
