  1. 1. Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging

    University essay from Göteborgs universitet / Institutionen för fysik

    Author : Henry Wittler; [2023-11-29]
    Keywords : ;

    Abstract : Methods of coherent diffractive imaging (CDI) rely on iterative algorithms to reconstruct the complex exit-surface wave (ESW) of the object being imaged from the measured diffraction intensity only. In this thesis we investigate by simulation the artifacts on reconstruction when noise are present in the measurement. READ MORE

  3. 2. LEO Satellite Connectivity for flying vehicles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jinxuan Chen; [2023]
    Keywords : LEO satellite network; satellite connectivity strategy; Nash-SAC; flying vehicles; LEO:s satellitnät; Strategi för satellitanslutning; Nash-SAC; flygande fordon;

    Abstract : Compared with the terrestrial network (TN), which can only support limited covered areas, satellite communication (SC) can provide global coverage and high survivability in case of an emergency like an earthquake. Especially low-earth orbit (LEO) satellites, as a promising technology, which is integral to achieving the goal of global seamless coverage and reliable communication, catering to 6G’s communication requirements.

  4. 3. Analog mixed signal front-end for Torque signal processing : A theoretical noise analysis and signal-chain evaluation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jesper Jansson; Wilhelm Nordgren; [2023]
    Keywords : Torque sensor; noise analysis; signal processing; analog-to-digital conversion; Momentgivare; brusanalys; signalbehandling; analog-till-digital omvandling;

    Abstract : High precision tightening of nuts and bolts together with traceability are important in many industrial assembly lines. To achieve this the nutrunner needs to accurately measure the torque which is applied to the nut, process the signal and provide the information to the controller that controls the tightening process.

  5. 4. Evaluating image analysis techniques for ultrasound optical tomography in breast tissue

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Henrik von Friesendorff; [2023]
    Keywords : ultrasound optical tomography; Monte Carlo light simulation; image reconstruction; Technology and Engineering;

    Abstract : Breast cancer is the most commonly diagnosed cancer in the world today and early detection is crucial to minimize the mortality. ”Ultrasound optical tomography” (UOT) is a method under development for deep tissue imaging. READ MORE

  6. 5. Simulating metal ct artefacts for ground truth generation in deep learning.

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Arthur Barakat; [2023]
    Keywords : Technology and Engineering;

    Abstract : CT scanning stands as one of the most employed imaging techniques used in clinical field. In the presence of metal implants in the field of view (FOV), distortions and noise appear on the 3D image leading to inaccurate bone segmentation, often required for surgery planning or implant design.
