  1. 16. Construction and Evaluation of a Numerical Model for Heat Transfer in a Ladle During Pre-heating : A Finite Volume Approach to the Diffusion Equation using Julia

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Gustaf Bjurstam; [2023]
    Nyckelord :Finite Volume Method; FVM; Diffusion equation; Ladle; Pre-heating; Baking; Heat equation; Heat transfer; Finita Volymmetoden; FVM; Diffusionsekvationen; Skänk; Förvärmning; Värmeledningsekvationen; Värmeledning;

    Sammanfattning : Heat transfer is key to understanding many processes in engineering. At a steel mill heat transfer is absolutely crucial to understanding most of the processes. One such a process is the pre-heating of a freshly relined ladle. LÄS MER

  3. 17. Design of a Sustainable Energy System for a Community Center in rural Mozambique : A Minor Field Study in Mozambique

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

    Författare :Emilia Säll Magnusson; Melchior Hahn; [2023]
    Nyckelord :Sustainable energy system; Solar PV system; off-grid; Community center; Rural Mozambique; Minor Field Study; Project Vita; Hållbart energisystem; Solcellssystem; off-grid; kultur- och fritidscentrum; Mozambiques landsbygd; Minor Field Study; Project Vita;

    Sammanfattning : Access to energy is an important part in the development of most countries and societies, linked to both social and economic growth. Nevertheless, 70% of the population in sub-Saharan Africa does not have access to electricity, which brings consequences to several of these areas. LÄS MER

  4. 18. Robust Non-Linear State Estimation for Underwater Acoustic Localization : Expanding on Gaussian Mixture Methods

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Diogo Antunes; [2023]
    Nyckelord :Robust state estimation; Underwater localization; Target tracking; Gaussian mixture; AUV; Estimação robusta de estado; Localização subaquática; Rastreamento de alvos; Mistura Gaussiana; AUV; Robust tillståndsuppskattning; Undervattenslokalisering; Målspårning; Gaussisk blandning; AUV;

    Sammanfattning : Robust state estimation solutions must deal with faulty measurements, called outliers, and unknown data associations, which lead to multiple feasible hypotheses. Take, for instance, the scenario of tracking two indistinguishable targets based on position measurements, where each measurement could refer to either of the targets or even be a faulty reading.

  5. 19. Discussion of Python Implementation Techniques for Discontinuous Galerkin Methods

    Kandidat-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Författare :Ulf Vestberg; [2023]
    Nyckelord :Best approximation; Orthogonal polynomials; Legendre polynomials; Integration; Full tensor product; Sum-factorization; Dune; Mathematics and Statistics;

    Sammanfattning : This paper discusses implementation techniques for integration methods within the Discontinuous Galerkin Methods. These methods are used to approximate solutions for differential equations. To do so, one must compute a polynomial, which is an approximation of the used function. LÄS MER

  7. 20. Using Social Media and Personality Predictions to Anticipate Startup Success

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Daniel Stenson; [2023]
    Nyckelord :Machine Learning; Startup Success Predictions; Founder Personalities; Natural Language Processing; Social Media Analysis; Big 5 Personality Framework; Feed-forward Neural Network; XGBoost.; Mathematics and Statistics;

    Sammanfattning : This thesis explores the potential of integrating predicted founder personalities, based on the Big 5 Personality Framework, into Machine Learning (ML) models to enhance the accuracy of early-stage startup success predictions. Leveraging Natural Language Processing (NLP) techniques, we extracted personality insights from founders' tweets, focusing on US startups funded between 2013 and 2015. LÄS MER
