  1. 1. Improving the experimental setup for ultrasound-optical tomography imaging

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ibtisam Dahir Ahmed; [2023]
    Nyckelord :Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

    Sammanfattning : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. LÄS MER

  3. 2. Transfer learning applied to a deep learning system for cardiac abnormality classification in electrocardiograms

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Sammanfattning : Cardiovascular diseases are a leading cause of death globally. Early diagnosis and treatment is of prime importance to prevent or mitigate health complications. Electrocardiogram (ECG) is a standard test modality used for early diagnosis of arrhythmias. The standard ECG uses 12 leads (i. LÄS MER

  4. 3. Exploring properties of a 10-dimensional pure spinor twistor transform

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Cesar Garcia; [2021]
    Nyckelord :String Theory; Twistors; Spinor-helicity variables;

    Sammanfattning : In this review, several tools used in the study of super-Yang-Mills scattering amplitudes are discussed, namely spinor-helicity and (super)twistor variables. These variables are then implemented in string theories in 4D, and a suitable generalization to 10D using pure spinors is discussed. LÄS MER

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Johannes Strömbom; [2021]
    Nyckelord :fingerprinting; laser speckles; speckle correlation; scattering transform; wavelets; feature detection;

    Sammanfattning : A cornerstone in the industry's ongoing digital revolution, which is sometimes referred to as Industry 4.0, is the ability to trace products not only within the own production line but also throughout the remaining lifetime of the products. LÄS MER

  7. 5. Musical Instrument Recognition using the Scattering Transform

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)
