  1. 1. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

    Master-uppsats, KTH/Materialvetenskap

    Författare :Helena Ek Jendrny; [2023]
    Nyckelord :AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

    Sammanfattning : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. LÄS MER

  3. 2. Convolution-compacted visiontransformers forprediction of localwall heat flux atmultiple Prandtlnumbers in turbulentchannel flow

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Yuning Wang; [2023]
    Nyckelord :Turbulent flow; Heat transfer; Vision transformer; Convolutional neural network; Machine learning;

    Sammanfattning : Predicting wall heat flux accurately in wall-bounded turbulent flows is critical for a variety of engineering applications, including thermal management systems and energy-efficient designs. Traditional methods, which rely on expensive numerical simulations, are hampered by increasing complexity and extremly high computation cost. LÄS MER

  4. 3. The mechanism behind internal injector deposits

    Master-uppsats, KTH/Kemiteknik

    Författare :Jenny Blomberg; [2023]
    Nyckelord :Biodiesel; deposit formation; engine oil; calcium sulphate; internal diesel injector deposits; Biodiesel; beläggningsbildning; motorolja; kalciumsulfat; interna dieselinjektorbeläggningar;

    Sammanfattning : Användningen av biobränslen har ökat för att minska utsläppen från fossila bränslen. Biobränslen kan dock leda till beläggningar inuti injektorn, vilka påverkar fordonets  körbarhet. LÄS MER

  5. 4. COMPARATIVE ANALYSIS OF MACHINE LEARNING LOAD FORECASTING TECHNIQUES

    Magister-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Humphry Takang Bate; [2023]
    Nyckelord :;

    Sammanfattning : Load forecasting plays a critical role in energy management, and power systems, enabling efficient resource allocation, improved grid stability, and effective energy planning and distribution. Without accurate very short term load forecasting, utility management companies face uncertain load patterns, unrealistic prices, and poor infrastructure planning. LÄS MER

  7. 5. Machine Learning of Laser Ultrasonic Data to Predict Material Properties

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Filip Tuvenvall; [2023]
    Nyckelord :Machine Learning; Laser Ultrasonics; Material Properties; Steel; Hardness of Steel;

    Sammanfattning : The hardness of steel is an important quality parameter for several industrial applications. Conventional mechanical testing is used in quality testing for material hardness and the method is time-consuming, can cause material mix-ups, and results in material waste. LÄS MER
