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

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

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

    Abstract : 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. READ MORE

  3. 2. Observation Based Modeling of Liquid Slosh in Drop Tests

    University essay from Lunds universitet/Matematik LTH

    Author : Victor Ekblad; Axl Roos; [2022]

    Keywords : Damaged Concrete Structure; Extended Finite Element Method XFEM ; Concrete Dam- aged Plasticity CDP ; Photogrammetry; Crack Detection Methods.;

    Abstract : Concrete has for decades been one of the main materials used to construct important structuressuch as dams and bridges. However, after years of service, the concrete structuresstart deteriorating and signs of damages start showing on the structure. READ MORE

  5. 4. A Model-Based Approach to Hands Overlay for Augmented Reality

    University essay from Linköpings universitet/Programvara och system

    Author : Fredrik Adolfsson; [2021]
    Keywords : Augmented Reality; Hands Overlay; Remote Guidance;

    Abstract : Augmented Reality is a technology where the user sees the environment mixed with a virtual reality containing things such as text, animations, pictures, and videos. Remote guidance is a sub-field of Augmented Reality where guidance is given remotely to identify and solve problems without being there in person. READ MORE

  6. 5. Image simulations of the mission Martian Moons eXploration

    University essay from KTH/Rymdteknik

    Author : Romain Domagala; [2020]
    Keywords : ;

    Abstract : Martian Moons eXploration is a JAXA-lead mission aiming at exploring the moons of Mars, Phobos and Deimos. The hyperspectral infrared camera provided by France should perform global mapping of Phobos at high resolution in order to characterize surface composition and therefore help determine the origins of the moons.
