  1. 1. Assessing the Effectiveness of Urban Trees with Skeletal Soils in Flood Risk Mitigation

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Molly Boberg; [2024]
    Nyckelord :Flood Management; Climate Adaptation; Nature-Based Solutions NBS ; Urban Trees; Skeletal Soil; Hydrologic Modelling; MIKE; Översvämningshantering; Klimatanpassning; Naturbaserade lösningar; Stadsträd; Skelettjord; Hydrologisk modellering; MIKE;

    Sammanfattning : With increased urbanization and climate change, heavy rainfall events and urban floods are becoming more frequent. To meet the demands for effective climate adaptation strategies and mitigation measures, Nature-Based Solutions (NBS) have received increased attention. LÄS MER

  3. 2. MANGO - Generating 2D-Magnetic Field Maps From Normal-Conducting Magnets Of Experimental Areas

    Master-uppsats, KTH/Fysik

    Författare :Ambre Visive; [2023]
    Nyckelord :Applied Physics; Particle Physics; MANGO; Magnetic Field Maps; Normal-Conducting Magnets; Finite-Element Modelling; Opera-2D; Git Repository; Python Package; Beam Lines; Experimental Areas; CERN; Tillämpad Fysik; Partikelfysik; MANGO; Magnetfältskartor; Normalkonduktiva Elektromagneter; Finit Elementmodellering; Opera-2D; Git Repository; Python Package; Partikelstrållinje; Experimentområden; CERN;

    Sammanfattning : This thesis discusses the development of MANGO, a tool created to model normal-conducting magnets which were installed in the 1970s in the experimental areas at CERN, and store their analysis. MANGO formulates an answer to two problems faced by the physicists of the Beam Department when they model a beam line: first, how to produce new magnetic field maps and, second, how to easily access existing ones? It contains a multi-use package that offers an automated process to produce magnetic field maps from finite-element models of magnets. LÄS MER

  4. 3. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Svante Rosenlind; [2023]
    Nyckelord :Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Sammanfattning : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. LÄS MER

  5. 4. Propulsion modelling of a generic submarine propeller

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Gustav Boman; [2023]
    Nyckelord :OpenFOAM; CFD; actuator line model; rotor disk; actuator disk; INSEAN E1619; propeller;

    Sammanfattning : Self propulsion modelling is important in order to accurately simulate ships and submarinesusing Computational Fluid Dynamics (CFD). However, fully resolved simulations of hull andpropeller geometries are computationally heavy and time consuming. As such there is a greatinterest in lower order CFD models of propellers. LÄS MER

  7. 5. Prediction of Reverberation Time in Office Spaces by Investigation of the Scattering Factor in Odeon

    Master-uppsats, KTH/Teknisk akustik

    Författare :Viktor Söderlund; [2023]
    Nyckelord :Scattering Factor; Reverberation Time; Odeon; Sabine; Arau-Puchades; Spridningsfaktor; Efterklangstid; Odeon; Sabine; Arau-Puchades;

    Sammanfattning : Accurate estimations of the reverberation time of furnished office spacesis essential as an acoustic consultant. A time efficient way to predict thefurniture’s effect is to investigate it by software modelling. The room acousticsoftware Odeon is suitable for doing this. LÄS MER
