  1. 6. Relating Process Data to Product Quality in Transmission Manufacturing

    Master-uppsats, KTH/Industriell produktion

    Författare :Claudia Tensi; [2021]
    Nyckelord :;

    Sammanfattning : Research has shown that vibration produced by a machine tool provides useful information for the maintenance of its structural parts. Thus, the vibration signal should also give information about tool wear and, consequently, surface roughness of the machined workpieces. LÄS MER

  3. 7. Seismic retrofitting assessment of historical churches : The reconstruction of The Basilica of Santa Maria di Collemaggio after the 2009 L’Aquila earthquake

    Uppsats för yrkesexamina på grundnivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Angelika Hedenström; [2020]
    Nyckelord :L’Aquila; earthquake; reconstruction; church; Basilica; Santa Maria di Collemaggio; Collemaggio; historical; heritage; preservation; seismic; retrofit; SHM;

    Sammanfattning : This study summarizes previous research to evaluate and verify the results of the extensive restoration of The Basilica of Santa Maria di Collemaggio after the 2009 L’Aquila earthquake. In addition, it aims at identifying the vulnerability factors and challenges in preserving these buildings. LÄS MER

  4. 8. Implementering av Structural Health Monitoring : SHM - system för detektering och övervakning av vanligt förekommande skador på betongbroar

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Jonathan Le Guillarme; Jakob Lindstam; [2019]
    Nyckelord :Structural Health Monitoring; Bridge Maintenance; Monitoring With Sensor Technology; Fibre Optical Sensors; Acoustic Emission; Bridge Constructions; Concrete Damages; Damage Mechanisms; Structural Health Monitoring; Tillståndsbedömning; Övervakning med sensorteknik; Fiberoptiska sensorer; Akustisk emission; Brokonstruktioner; Betongskador; Skademekanismer;

    Sammanfattning : Sverige har som många länder runt om i världen en åldrande infrastruktur och behovet av underhåll stiger. I en artikel i Svenska Dagbladet från 21/9–2018 redovisar analys- och teknikkonsultföretaget WSP en grov uppskattning att 300 miljarder kronor behöver investeras för att rusta upp existerande infrastruktur.

  5. 9. Structural Health of a concrete tunnel lining under complex in situ loading

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :LEONARDO DALLA ROSA; [2019]
    Nyckelord :;

    Sammanfattning : Supporting structures were designed for a utility tunnel in hard rock which was to be intersectedby some road tunnels. With the intersections involving partial overlapping between the idealcross-sections, a concrete lining and post-tensioned steel cables were added to support theutility tunnel prior to the excavation of the road tunnels.

  7. 10. Quantifying uncertainty in structural condition with Bayesian deep learning : A study on the Z-24 bridge benchmark

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

    Författare :David Steinar Asgrimsson; [2019]
    Nyckelord :Bayesian Deep Learning; Autoencoders; Bridge Structural Health Monitoring; Bridge Damage Detection;

    Sammanfattning : A machine learning approach to damage detection is presented for a bridge structural health monitoring system, validated on the renowned Z-24 bridge benchmark dataset where a sensor instrumented, threespan bridge was realistically damaged in stages. A Bayesian autoencoder neural network is trained to reconstruct raw sensor data sequences, with uncertainty bounds in prediction. LÄS MER
