  1. 1. Experimental Investigation of High Prandtl Number Flow in Additive Manufactured Channels

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :LINDA YANG; [2023]
    Nyckelord :Additive manufacturing; Heat transfer; Darcy friction factor; Nusselt number; Minichannel.; Friformsframställning; Värmeöverföring; Darcy friction factor; Nusselt number; Minikanal.;

    Sammanfattning : Additive manufacturing (AM) rapidly evolves and expands into new industries dueto its great design freedom and time savings. Injection molding is an excellentindustry where AM can help reduce cooling time by printing complex coolingchannels for more effective and uniform cooling. LÄS MER

  3. 2. Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Alejandra Fernandez Castaneda; [2022]
    Nyckelord :Cream; microestructure; environmental stress cracking; food technology and nutrition; Agriculture and Food Sciences;

    Sammanfattning : Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC).

  4. 3. BNPL Probability of Default Modeling Including Macroeconomic Factors: A Supervised Learning Approach

    Master-uppsats, KTH/Matematisk statistik

    Författare :Patrik Hardin; Robert Ingre; [2021]
    Nyckelord :Buy Now Pay Later; IFRS 9; Probability of Default; Expected Credit Loss; Macroeconomic factors; Machine Learning; Artificial Neural Network; XGBoost;

    Sammanfattning : In recent years, the Buy Now Pay Later (BNPL) consumer credit industry associated with e-commerce has been rapidly emerging as an alternative to credit cards and traditional consumer credit products. In parallel, the regulation IFRS 9 was introduced in 2018 requiring creditors to become more proactive in forecasting their Expected Credit Losses and include the impact of macroeconomic factors.

  5. 4. Detection of glass in RDF using NIR spectroscopy

    Master-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Philip Hedlund; [2018]
    Nyckelord :NIR; spectroscopy; RDF; glass; CFB; boiler; performance; losses; NIR; spektroskopi; RDF; glas; CFB; panna; prestanda; förluster;

    Sammanfattning : Purpose of this study was to investigate the possibilities of using Near-infrared (NIR) spectroscopy to detect glass in refuse derived fuel (RDF) as well as what on-line data of glass content could be used for in terms of boiler operation and performance determination. Sample configurations were done with dried RDF (to prevent mass loss due to moisture and spectroscopic disturbance) and increasing concentrations of colored soda-lime glass, total of 100 samples.

  7. 5. Investigation and Validation of Cooling Loss Models for Axial Gas Turbines

    Master-uppsats, KTH/Energiteknik

    Författare :Jacob Händestam; Eric Jacobson; [2017]
    Nyckelord :axial gas turbines; one-dimensional; aerodynamics; cooling; losses; loss models; validation; axiella gas turbiner; endimensionell; aerodynamik; kylning; förluster; förlust modellering; validering;

    Sammanfattning : Detta arbete behandlar undersökningen och valideringen av kylförlustmodellen i det nyligen framtagna programmet för endimensionell turbindesign, Mean Line Tool (MLT), skapat av Siemens Industrial Turbomachinery AB (SIT). Huvudsyftet är att undersöka med vilken noggrannhet MLT kan prediktera de extra aerodynamiska förluster som uppstår vid injektion av kylluft i en turbinpassage. LÄS MER
