  1. 1. Towards Sustainable Transport: A case study on modal shift for temperature-controlled goods between northern Norway and central Europe

    University essay from Göteborgs universitet/Graduate School

    Author : Love Kristoffersson; Etienne Skowronski; [2023-07-03]
    Keywords : road-rail transport; temperature-controlled goods; cross-border; modal shift; transportation network;

    Abstract : In line with the ambitious sustainability goals set by the European Union to reduce transport emissions, there is a growing interest for sustainable freight transport across Europe. Rail transportation has emerged as a preferred mode of choice for shippers and freight forwarders, given its sustainability advantage of transporting larger volumes on longer distances. READ MORE

  3. 2. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Erik Nordlund; [2023]
    Keywords : Inductive switch point heating; Turnout heating; railway turnout heating; Inductive heating;

    Abstract : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance.

  4. 3. Reliability-Based Sensitivity Analysis of the Dynamic Response of Railway Bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Hasan Al-Zubaidi; [2022]
    Keywords : Railway bridges; High-speed trains; Simply supported beam; Global sensitivity analysis; Uncertainty quantification; Reliability; Ballast instability; Running safety; Passenger comfort;

    Abstract : In response to the planned increase in operational speeds and axle loads of passengertrains that may lead to resonance-induced excessive vibrations in railway bridges,recent studies examined the reliability of bridges concerning train running safety andpassenger comfort limit states. In this respect, valuable information regarding theimportance of input variables can be obtained by conducting Sensitivity Analysis (SA). READ MORE

  5. 4. Design, Analysis and Implementation of a Drive System for Delsbo Electric Light Rail Vehicle

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

    Author : Daniel Marklund; Maria Lindh; [2022]
    Keywords : pulse and glide; rail vehicle; drive system; Delsbo Electric;

    Abstract : The aim of this project is to design and implement a drive system and a driving strategy for a lightweight, battery-driven rail vehicle partaking in the Delsbo Electric student competition. The goal of the competition is to create a vehicle which consumes as little energy as possible. READ MORE

  6. 5. Development of a Software Reliability Prediction Method for Onboard European Train Control System

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

    Author : Guillaume Pierre Longrais; [2021]
    Keywords : Machine Learning; Software Reliability Growth Prediction; Linear Regression; Artificial Neural Network; Multi-Layer Perceptron; Imperialist Competitive Algorithm; Long Short-Term Memory Network; Convolutional Neural Network; Maskininlärning; förutsägelse av tillväxten av programvarans tillförlitlighet; linjär regression; artificiellt neuralt nätverk; flerskikts-perceptron; imperialistisk konkurrensalgoritm; nätverk med långt korttidsminne; konvolutionellt neuralt nätverk;

    Abstract : Software prediction is a complex area as there are no accurate models to represent reliability throughout the use of software, unlike hardware reliability. In the context of the software reliability of on-board train systems, ensuring good software reliability over time is all the more critical given the current density of rail traffic and the risk of accidents resulting from a software malfunction.
