  1. 1. Novel Approaches for Application of Principal Component Analysis on Dynamic PET Images for Improvement of Image Quality and Clinical Diagnosis

    Författare :Pasha Razifar; Ewert Bengtsson; Mats Bergström; Harald Schneider; Habib Zaidi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Dynamic PET; Noise Correlation; PCA; Image Quality; Slice-Wise; Pixel-Wise; Masked-Volume-Wise; Pre-normalization; Bildanalys; Image analysis; Bildanalys;

    Sammanfattning : Positron Emission Tomography, PET, can be used for dynamic studies in humans. In such studies a selected part of the body, often the whole brain, is imaged repeatedly after administration of a radiolabelled tracer. LÄS MER

  3. 2. Structured Representations for Explainable Deep Learning

    Författare :Federico Baldassarre; Hossein Azizpour; Josephine Sullivan; Kevin Smith; Hamed Pirsiavash; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Explainable AI; Deep Learning; Self-supervised Learning; Transformers; Graph Networks; Computer Vision; Explainable AI; Deep Learning; Self-supervised Learning; Transformers; Graph Networks; Computer Vision; Datalogi; Computer Science;

    Sammanfattning : Deep learning has revolutionized scientific research and is being used to take decisions in increasingly complex scenarios. With growing power comes a growing demand for transparency and interpretability. The field of Explainable AI aims to provide explanations for the predictions of AI systems. LÄS MER

  4. 3. Compression mechanisms and strength properties of semi- isostatically densified wood

    Författare :Jonas Blomberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology; Densified wood;

    Sammanfattning : Since most strength properties increase with increased wood density, densifying wood through compression will increase strength and wear resistance. After densification, wood with originally low density can substitute denser wood and originally dense wood can be used for purposes where wood is considered too soft, e.g. LÄS MER

  5. 4. Autonomous bridge inspection based on a generated digital model

    Författare :Ali Mirzazade; Björn Täljsten; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggkonstruktion; Structural Engineering;

    Sammanfattning : Railway owners manage geographically dispersed networks comprising major elements of ageing infrastructure that are very susceptible to natural hazards. Consequently, transport agencies must address maintenance issues to guarantee serviceability and safety. LÄS MER
