    Nyckelord :Alpha-iron; Chromium carbide; Cr7C3; Fe; Theoretical investigation; Orthorhombic; X-ray diffraction pattern; XRD; VASP; VESTA; Body-centered-cubic; Ferrite; Density functional theory; DFT; Surface relaxation; Simulation; Calculation; Energy relaxation; Slab models; Coherency; Surface energy; Interfacial energy; Alfa-järn; Kromkarbid; Cr7C3; Fe; Teoretisk undersökning; Ortorombisk; Röntgendiffraktion; XRD; VASP; VESTA; Ytenergi; Koherent; Simulering; Beräkning; Järnkarbid; DFT; Täthetsfunktionalanalys;

    Sammanfattning : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). LÄS MER

  2. 22. The Predictive Power of Implied Volatility in Option Pricing

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Lovisa Berglund; [2023]
    Nyckelord :Option Pricing; Black-Scholes; Finance; Implied Volatility; Applied Mathematics; Machine Learning; Optionsprissättning; Black-Scholes; Finans; Implicit Volatilitet; Tillämpad Matematik; Maskininlärning;

    Sammanfattning : During the last few years, financial derivatives have been growing in trading volume. There seem to be a high demand and supply of derivatives on the market and one common derivative is the option contract. The option contract is frequently the subject of studies and many different pricing models have been created for options. LÄS MER

  3. 23. Exploring the impact of economic and social factors on stock market performance

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Vincent Hallberg; William Hjorth; [2023]
    Nyckelord :regression analysis; societal development; domestic stock market; bachelor thesis; applied mathematics; macroeconomic factors; regressionsanalys; samhällsutveckling; inhemsk aktiemarknad; kandidatexamensarbete; tillämpad matematik; makroekonomiska faktorer;

    Sammanfattning : This study seeks to investigate the relationship between human development factors and domestic stock markets using a multiple linear regression model. Despite efforts to improve the model's explanatory power, the findings indicate that the model fails to confirm the research question. LÄS MER

  4. 24. The Applicability and Scalability of Graph Neural Networks on Combinatorial Optimization

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Peder Hårderup; [2023]
    Nyckelord :applied mathematics; combinatorial optimization; machine learning; graph neural networks; scalability; tillämpad matematik; kombinatorisk optimering; maskininlärning; grafiska neurala nätverk; skalbarhet;

    Sammanfattning : This master's thesis investigates the application of Graph Neural Networks (GNNs) to address scalability challenges in combinatorial optimization, with a primary focus on the minimum Total Dominating set Problem (TDP) and additionally the related Carrier Scheduling Problem (CSP) in networks of Internet of Things. The research identifies the NP-hard nature of these problems as a fundamental challenge and addresses how to improve predictions on input graphs of sizes much larger than seen during training phase.

  5. 25. Utveckling av upphöjda plattformar för testrigg

    Kandidat-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Alex Ljungström; Martin Johansson; [2023]
    Nyckelord :Utveckling av upphöjda plattformar; Maskinteknik; Produktutveckling;

    Sammanfattning : På BorgWarners fabrik i Landskrona tillverkas och utvecklas flera typer av differentialväxlar för fyrhjulsdrivna bilar. Ett steg i utvecklingsprocessen av dessa differentialväxlar är end-of-line-tester som utförs i en så kallad testrigg. Flera av dessa testriggar är nu positionerade på golvet. LÄS MER
