  1. 1. HRTF-Based Sound Field Interpolation in the Presence of a Human Head

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Anton Björkman; [2023]
    Nyckelord :Sound field interpolation; HRTF; head-related transfer function; kernel ridge regression; in-ear sound estimate; Helmholtz equation; Mathematics and Statistics;

    Sammanfattning : There are different ways of evaluating the sound pressure in a sound field. Doing so is an essential part of several applications, such as active sound control and voice analysis. LÄS MER

  3. 2. Augmentation for Generalization

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Joel Ottosson; [2022]
    Nyckelord :machine learning; microscopy; segmentation; augmentation; neural network; Mathematics and Statistics;

    Sammanfattning : To be able to automatically segment cells in microscopic images would give biologist a new tool to gather crucial data in quantities not possible by manual work. This is however not a trivial problem and has proven to be very difficult, especially if the images are in 3D. LÄS MER

  4. 3. Hierarchical Clustering To Improve Portfolio Tail Risk Characteristics

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Adam Eidenvall; [2021]
    Nyckelord :Hierarchical Clustering; Asset Allocation; Portfolio Construction; Graph Theory; Machine Learning; Risk Parity; Regime Shift; Bootstrapping; Walk Forward; Mathematics and Statistics;

    Sammanfattning : Many agree that estimating portfolio risks has better estimation possibilities, than estimations on returns. Therefore investors attempts to construct better, more efficient riskmanaged portfolios by diversifying portfolios through factors rather than traditional asset classes. LÄS MER

  5. 4. Uppföljning av absoluta tjälrörelser : En fallstudie av väg E10 i Kiruna

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Hampus Elmehög; [2019]
    Nyckelord :frost; frost heave; PMS objekt; road construction; segregation potential theory; PMS objekt; segregation potential theory; tjäle; tjällyftning; vägbyggnad;

    Sammanfattning : Detta examensarbete har haft som mål att undersöka tjällyftningen hos en väg i en fältstudie och utvärdera reliabiliteten hos två olika modeller för skattning av tjällyftning. Modellerna som har studerats är Trafikverkets nuvarande, vilken är implementerad i deras vägdimensioneringsverktyg PMS Objekt, samt segregation potential theory. LÄS MER

  7. 5. The Dirichlet-Neumann iteration – Three-field case: Methods and analyses

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Ivo Dravins; [2018]
    Nyckelord :Dirichlet-Neumann; three field; three domains; Laplace equation; Poisson equation; coupled heat equations; steady-state; Mathematics and Statistics;

    Sammanfattning : We construct and analyze Dirichlet-Neumann iterations for the 1D Poisson equation. Specifically, we wish to gain insight into how the convergence depends on material coefficients when solving coupled linear heat equations on three non-overlapping domains. We first consider the two-domain case and then extend the method to three domains. LÄS MER
