  1. 1. From Manual to Robotic -Assessing the Potential Benefits of Automation in Railway Inspections and Maintenance

    Uppsats för yrkesexamina på grundnivå, Lunds universitet/Trafik och väg

    Författare :Benjamin Furberg; [2023]
    Nyckelord :Railway; Inspections; Maintenance; Robotics; Automation; Turnouts; Technology and Engineering;

    Sammanfattning : The railway industry plays a crucial role in the global freight transport and passenger mobility market, providing an efficient and low-emitting mode of transportation. However, to compete with other modes of transportation, the railway must improve its reliability. LÄS MER

  3. 2. Tracking motion in mineshafts : Using monocular visual odometry

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Karl Suikki; [2022]
    Nyckelord :Monocular Visual Odometry; Tracking; ORB; SIFT;

    Sammanfattning : LKAB has a mineshaft trolley used for scanning mineshafts. It is suspended down into a mineshaft by wire, scanning the mineshaft on both descent and ascent using two LiDAR (Light Detection And Ranging) sensors and an IMU (Internal Measurement Unit) used for tracking the position.

    Sammanfattning : Syftet med detta examensarbete har varit att analysera potentialen och konsekvenserna av att använda drönarteknik för järnvägsunderhåll i Sverige. Arbetet har genomförts i samarbete med företaget Nordic Infracenter, som ett underprojekt till projektet Framtidens Järnväg. LÄS MER

  5. 4. A Machine Learning-Based Approach for Fault Detection of Railway Track and its Components

    Master-uppsats, Luleå tekniska universitet/Drift, underhåll och akustik

    Författare :Johnny Asber; [2020]
    Nyckelord :Condition Based Maintenance in Railway; Machine Learning; Deep Learning; ResNet-50;

    Sammanfattning : The hard equation of railway safety versus the high commercial profits can only be achieved through the use of new inspection methods supported by modern technologies. The track and its components can have different types of troubles, such as rail surface defects, broken sleepers, missing fasteners, and irregular ballast levels. LÄS MER

  7. 5. Replicating noise in video : a comparison between physics-based and deep learning models for simulating noise

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

    Författare :Jonas Wedin; [2020]
    Nyckelord :;

    Sammanfattning : Algorithms that track objects in video following Newtonian physics can often be affected by noise in the data. Some types of noise might be hard or expensive to capture, so to be able to augment or generate a new data set from models replicating a certain type of noise can be useful. LÄS MER
