  1. 6. CFD Analyses for Wind Load AssessmentCFD Analyses for Wind Load Assessment : Wind-induced vibrations in the Bomarsunds Bridge hangers

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Fatiha El Azrak; [2023]
    Nyckelord :;

    Sammanfattning : The trend in recent years of building longer and slender bridge components has introduced new challenges to ensure their stability and strength. This master thesis focuses on the effects of wind-induced vibrations in the context of long, slender arch bridge components, particularly the recently constructed Bomarsunds Bridge in Åland, Finland.

  3. 7. Transversal Construction of Topological Gates on Multiqubit Quantum Codes

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Sheila Chauwinoir; [2022]
    Nyckelord :entanglement; local SU 2 evolution; topological phase factors; topological gates; transversal gates; multiqubit quantum codes; Hopf fibration;

    Sammanfattning : We study the possibility of constructing quantum gates using topological phases, which originate from local SU(2) evolution of entangled multiqubit systems. For this purpose, logical codewords using two-, three- and nine-qubit entangled states are defined and possible implementations of topological gates on these codes, are examined. LÄS MER

  4. 8. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :William Tönnberg; [2022]
    Nyckelord :Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Sammanfattning : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. LÄS MER

  5. 9. Pediatric Brain Tumor Type Classification in MR Images Using Deep Learning

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Tamara Bianchessi; [2022]
    Nyckelord :pediatric brain tumors; MR image analysis; deep learning; classification; model explainability;

    Sammanfattning : Brain tumors present the second highest cause of death among pediatric cancers. About 60% are located in the posterior fossa region of the brain; among the most frequent types the ones considered for this project were astrocytomas, medulloblastomas, and ependymomas. LÄS MER

  7. 10. Railway Fastener Fault Detection using YOLOv5

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

    Författare :Alva Efraimsson; Elin Lemón; [2022]
    Nyckelord :Fastener Fault Detection; Object Detection; YOLOv5; Machine Learning; Railway Maintenance; Proactive Maintenance;

    Sammanfattning : The railway system is an important part of the sociotechnical society, as it enables efficient, reliable, and sustainable transportation of both people and goods. Despite increasing investments, the Swedish railway has encountered structural and technical problems due to worn-out infrastructure as a result of insufficient maintenance. LÄS MER
