1. 16. 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.

4. 18. 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

5. 19. Parametric Studies of Train-Track-Bridge Interaction : An evaluation of the dynamic amplification due to track irregularities for freight transport

   University essay from KTH/Bro- och stålbyggnad

   Author : Rasmus Elm Dahlman; Emil Lundberg; [2021]
   Keywords : Dynamics; dynamic amplification factor; railway bridge; train-track-bridge interaction; vehicle model; track irregularities; PSD; Dynamisk förstoringsfaktor; dynamik; järnvägsbroar; tåg-spår-bro interaktion; fordonsmodell; spårojämnheter; PSD;

   Abstract : In this thesis a train-track-bridge interaction (TTBI) model is developed in order to study the dynamic amplification from track irregularities on railway bridges traversed by freight trains. These simulations are of great importance since rail freight transport is expected to increase in order to meet the climate goals. READ MORE

6. 20. Urban infrastructure inundation risk from permanent sea-level rise scenarios in London (UK), Bangkok (Thailand) and Mumbai (India): A comparative analysis

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Shawn Pace; [2021]
   Keywords : Geography; GIS; Climate Change; Sea-Level Rise; Urban Infrastructure; DEM; London; Mumbai; Bangkok; Earth and Environmental Sciences;

   Abstract : Due to anthropogenically created climate change, global cities are facing inundation by rising sea levels. This study aimed to fill knowledge gaps in understanding the exposure of urban infrastructure such as roads, railways, buildings and parks to sea-level rise (SLR) scenarios, and how this would affect local populations.
