  1. 11. Evaluation of deep learning methods for industrial automation

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Ragnar Onning; [2023]
    Nyckelord :artificial intelligence; machine learning; deep learning; cnn; transformer; swin; swin transformer;

    Sammanfattning : The rise and adaptation of the transformer architecture from natural language processing to visual tasks have proven a useful and powerful tool. Subsequent architectures such as visual transformers (ViT) and shifting window (SWIN) transformers have proven to be comparable and oftentimes exceed convolutional neural networks (CNNs) in terms of accuracy.

  3. 12. Identifiering av felplacerade komponenter på ett kretskort med bildbehandling

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Avdelningen för datavetenskap och samhällsbyggnad

    Författare :Adam Chabchoub; [2023]
    Nyckelord :Image processing; Algorithm; Reference image; Histogram matching; Centroid; Bildbehandling; Algoritm; Referensbild; Histogrammatchning; Centroid;

    Sammanfattning : Teknologiska framsteg påverkar tillverkningsindustrin genom att integrera tester för kretskortens status, lödning och elektriska egenskaper. En pick-and-place-maskin används för att verifiera komponentpositioner på kretskortet, men underhåll och re-paration av dessa maskiner medför stora kostnader. Industry 4. LÄS MER

    Sammanfattning : The increasing demand for mobile data has placed significant strain on radio access networks (RANs), leading to a continuous need for increased network capacity. In keeping with that, a significant advancement in modern RANs is the ability to utilize several receivers and transmitters, to allow for beamforming. LÄS MER

  7. 15. Comparison of Operator and Nonoperator Managed 5G Non-Public Networks (NPNs): Implications for Network Architectures and Cost Structures

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

    Författare :Amina Ahmed; [2023]
    Nyckelord :;

    Sammanfattning : In the evolving landscape of communication technologies, 5G Non-Public Network (NPN) enables organizations, enterprises, and industries to have specialized, highperformance connectivity tailored to their needs. It operates independently of Mobile Public Networks (MNOs) and is designed to provide secure, low-latency, and reliable communication in two broad types: standalone or public-integrated. LÄS MER
