  1. 1. Data Augmentations for Improving Vision-Based Damage Detection : in Land Transport Infrastructure

    Master-uppsats, KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Författare :Punnawat Siripatthiti; [2023]
    Nyckelord :Computer Vision; Data Augmentation; Object Detection; Crack Detection; Road Damage Detection; Sleeper Defect Detection; datorseende; dataökning; objektdetektering; sprickdetektering; vägbeläggning; järnvägsslipers;

    Sammanfattning : 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

  3. 2. Development of a DEM-FEM framework for infrastructure simulations

    Master-uppsats, Göteborgs universitet / Institutionen för fysik

    Författare :Anita Ullrich; [2022-09-20]
    Nyckelord :;

    Sammanfattning : This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with elastic bodies. LÄS MER

  4. 3. 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

    Sammanfattning : In Sweden, there are students who live in small student apartments. These apartments can be called compact living as a student apartment can be as small as 16 square meters. To take advantage of the place that is in small homes, it would be good if larger furniture could be combined into a piece of furniture. LÄS MER
