  1. 16. Modelling Critical Points in Infrastructure

    University essay from Uppsala universitet/Datorteknik

    Author : Ted Jallow; [2022]
    Keywords : Infrastructure; modelling; critical points; railway system; networks; centrality; cyber physical systems;

    Abstract : The aim of this paper was to investigate whether infrastructure could be modelled in order to find critical points using network science and graph theory. Since a lot of information about ourinfrastructures is publicly available, an attacker might exploit this to find vulnerabilities in our systems. READ MORE

  3. 17. Pantograph-catenary wear modelling using dynamic simulation

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Gaston Holmström; [2022]
    Keywords : Wear modelling; catenary pantograph interaction; mechanism; conditional; railway; slitagemodellering; kontaktledning pantograf interaktion; mekanism; konditionell; järnväg;

    Abstract : Wear condition modelling is a research topic which lately has increased in popularitydue to its significance to the railway industry. Large sums are spent on maintenanceof the network every year, which has generated a demand for understanding and predictingwear mechanisms in a multitude of components within both railway vehiclesand infrastructure.

  4. 18. Railway Fastener Fault Detection using YOLOv5

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

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

    Abstract : 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. READ MORE

  5. 19. Detecting Defective Rail Joints on the Swiss Railways with Inception ResNet V2 : Simplifying Predictive Maintenance of Railway Infrastructure

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Anton Lu; [2022]
    Keywords : Rail Defect Detection; Rail Image Classification; Rail Joints; Object Detection; Image Classification; Deep Learning; Järnvägsfeldetektering; Järnvägsbildigenkänning; Järnvägsskarvar; Objectigenkänning; Bildklassificering; Djupinlärning;

    Abstract : Manual investigation of railway infrastructure is a labor-intensive and time-consuming task, and automating it has become a high priority for railway operators to reduce unexpected infrastructure expenditure. In this thesis, we propose a new image classification approach for classifying defect and non-defective rail joints in image data, based on previous fault detection algorithms using object detection.

  6. 20. Another Lunatic Line? An Economic Evaluation of the Standard Gauge Railway in Kenya

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Hedda Most; [2021]
    Keywords : Transportation Infrastructure; Railways; Kenya; Differences-in-Differences; Income; Economic Growth; Business and Economics;

    Abstract : This research paper seeks to examine the emerging role of transportation infrastructure on economic activity in low-income countries due to its vital part in facilitating deeper integration of markets, hence fostering inclusive growth and prosperity for the poor. Although its economic causal framework suggests ambiguous results, transportation investments account for the largest share of the World Bank's lending to developing countries. READ MORE
