  1. 21. Integration of Attribute-Based Encryption and IoT: An IoT Security Architecture

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Ziyad Elbanna; [2023]
    Nyckelord :Internet of things; Attribute based encryption; Fine-grained access control; Key revocation; Proxy re-encryption;

    Sammanfattning : Services relying on internet of things (IoTs) are increasing day by day. IoT makes use of internet services like network connectivity and computing capability to transform everyday objects into smart things that can interact with users, and the environment to achieve a purpose they are designed for.

  3. 22. Deep Learning Based Detection, Quantification, and Subdivision of White Matter Hyperintensities in Brain MRI

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Inna Fryckstedt; [2023]
    Nyckelord :white matter hyperintensities; white matter lesions; deep learning; machine learning; DL; ML; MRI; iNPH;

    Sammanfattning : White matter hyperintensities (WMH) are commonly found as bright regions in brain MRI images in older individuals. They are associated with various neurological and vascular diseases, such as stroke, dementia, and cardiovascular disorders. LÄS MER

  4. 23. Self-supervised pre-training of an attention-based model for 3D medical image segmentation

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

    Författare :Albert Sund Aillet; [2023]
    Nyckelord :Computer vision; Deep learning; 3D Medical image segmentation; Self-supervised learning; Datorseende; Djupinlärning; 3D Medicinsk bildsegmentering; Självövervakad träning;

    Sammanfattning : Accurate segmentation of anatomical structures is crucial for radiation therapy in cancer treatment. Deep learning methods have been demonstrated effective for segmentation of 3D medical images, establishing the current standard. However, they require large amounts of labelled data and suffer from reduced performance on domain shift. LÄS MER

  5. 24. Cache behaviour analysis for graph algorithms

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Johan Söderström; [2023]
    Nyckelord :;

    Sammanfattning : Graph processing is an ever-increasing significant area of research in the wake of the demand for efficient tools that process data such as graphs, which can describe sets of objects (vertices) and their relations to each other (edges). Graph algorithms traverse these graphs by visiting their vertices or additionally calculating some properties about them such as how significant a specific vertex is in the context of the greater graph.

  7. 25. Heart- and Sapwood Segmentation on Hyperspectral Images using Deep Learning

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Samuel Hallin; Simon Samnegård; [2023]
    Nyckelord :Computer Vision; Hyperspectral Imaging; Heartwood; Sapwood; Deep Learning; Segmentation; Dimensionality Reduction; PCA; PLS; SVM; U-NET; U-within-U-Net;

    Sammanfattning : For manufacturers in the wood industry, an important way to make the production more effective is to automate the process of detecting defects and different attributes on boards. One important attribute on most boards is heartwood and sapwood. LÄS MER
