1. Data Augmentations for Improving Vision-Based Damage Detection : in Land Transport Infrastructure
Master-uppsats, KTH/Lantmäteri – fastighetsvetenskap och geodesiSammanfattning : Crack, a typical term most people know, is a common form of distress or damage in road pavements and railway sleepers. It poses significant challenges to their structural integrity, safety, and longevity. Over the years, researchers have developed various data-driven technologies for image-based crack detection in road and sleeper applications. LÄS MER
2. U - Net Based Crack Detection in Road and Railroad Tunnels Using Data Acquired by Mobile Device
Master-uppsats, KTH/GeoinformatikSammanfattning : Infrastructures like bridges and tunnels are significant for the economy and growth of countries, however, the risk of failure increases as they getting aged. Therefore, a systematic monitoring scheme is necessary to check the integrity regularly. LÄS MER
3. A digital image correlation method for detection of fatigue cracks in non-load carrying T-joints
Master-uppsats, KTH/LättkonstruktionerSammanfattning : In dynamical loaded welded structures fatigue life is often a limiting factor. Common practise is to reduce nominal stress by increased material thickness which leads to oversized, heavy structures. Those practises are replaced by improvement of production and designingtechniques to utilize better properties of high strength steels. LÄS MER
4. Provningsmetodik förkretskort, samt undersökningav termisktcyklade kretskort
Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : Lödfogar på kretskort utsätts för spänningar i samband med temperaturväxlingar. Dessa spänningar leder så småningom till utmattningsbrott. LÄS MER
