  1. 1. Aerodynamics simulations of Scania trucks using OpenFOAM

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Ziyi Liu; [2024]
    Nyckelord :Heavy-duty truck; Computational fluid dynamics; Air drag; OpenFOAM;

    Sammanfattning : In the field of heavy-duty vehicles, fuel efficiency and environmental protection are factors that need to be focused on, while the aerodynamic drag generated during vehicle travelling is one of the most influential aspects. This thesis delves into the aerodynamic simulation of Scania trucks using the open-source Computational Fluid Dynamics (CFD) tool, OpenFOAM v2206. LÄS MER

  3. 2. Quantum Optical Description of High-order Harmonic Generation

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Isabel Moreno; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.

  4. 3. N-body simulations of exoplanets and their moons

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Lydia Schollmeier; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. LÄS MER

  5. 4. Development and Implementation of Techniques for the Simulation and Processing for Future SAR Systems

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Tim Kinnunen; [2023]
    Nyckelord :Synthetic Aperture Radar; SAR; Reverse Backprojection Algorithm; RBPA; Backprojection Algorithm; SAR simulator; SAR processing;

    Sammanfattning : Synthetic Aperture Radar (SAR) is a type of radar system that can generate high-resolution images with which one can detect subtle changes on the scale of centimetres from space. It can operate in any weather condition and during both day and night, making it unique compared to optical sensors. LÄS MER

  7. 5. 3D Modeling of Factory Scenarios for 5G Evaluations

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Haodong Zhao; [2023]
    Nyckelord :;

    Sammanfattning : 5G is a key enabler for a variety of use cases in smart manufacturing which requires communications with high reliability and low latency. In a dynamic industrial environment, objects such as machines, production lines, storage shelves, robotic arms, and automatically guided vehicles may cause fading and have a large impact on radio propagation.
