    Author : Elias Estensen; [2022]
    Keywords : Helmholtz; wave equation; acoustics; ocean acoustics; numerical analysis; computational science; finite differences; summation by parts; sbp; waveholtz; cylindrical coordinates; sediment layers; interface; super-grid; super grid; absorbing layer; Helmholtz; vågekvationen; akustik; undervattensakustik; numerisk analys; beräkningsvetenskap; finita differenser; summation by parts; sbp; cylindriska koordinater; waveholtz; sedimentskikt; interface; super-grid; absorberande lager;

    Abstract : In this report, we study how finite differences can be used to simulate acoustic wave propagation originating from a point source in the ocean using the Helmholtz equation. How to model sediment layers and the vast size of the ocean is studied in particular. READ MORE

  3. 2. Permeability of temporary restorative materials exposed to underwater pressure

    University essay from Malmö universitet/Odontologiska fakulteten (OD)

    Author : Elias Sjöberg; Daniel Hallin; [2020]
    Keywords : dental leakage; dental restoration; dental restoration temporary; diving; pressure; naval medicine;

    Abstract : Området submarin miljö och dentala förhållanden finns det få studier inom. Detta ger behandlare svårigheter att ta evidensbaserade behandlingsbeslut för grupper som utsätts för hyperbariskt tryck. För att kunna föra fram kvalitativa studier och odontologisk kunskap krävs tillförlitliga metoder. READ MORE

  4. 3. Methods for numerical analysis of soil-structure interaction

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Elias Lager; Pontus Karlsson; [2019]
    Keywords : Technology and Engineering;

    Abstract : All buildings need a foundation that supports the structure. Since a layer of soil is most often in between a structure and the bedrock, a soil-structure interaction between the foundation and the soil beneath occurs. READ MORE
