  1. 1. Vehicle dynamics modelling of electromagnetic suspensions for MAGLEV applications

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

    Author : Léa Chatelais; [2024]
    Keywords : MAGLEV; Dynamics; Requirements; Suspension; Vehicle modeling; MATLAB; MAGLEV; Dynamisk; Fordran; Upphängning; Fordon modell; MATLAB;

    Abstract : MAGnetic LEVitation Guidance System (MAGLEV) technology was commercially introduced relatively recently in the guided transport field. It is based on removing the wheels and rails of classic railway systems and supporting and guiding the train with magnets and magnetic forces instead. READ MORE

  3. 2. Simultaneous scheduling of railway maintenance and trains : Modelling and solving train interactions close to a maintenance operation

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

    Author : Pauline Vaillant; [2023]
    Keywords : Optimization; Linear programming; Heuristics; Railway scheduling; Maintenance planning; Optimering; Linjärprogrammering; Heuristik; Järnvägsplanering; Underhållsplanering;

    Abstract : Rail transport plays a key role in the mobility of passengers and goods. It is expected to grow the decarbonization of society. In that context, it is important to use the railway network efficiently, and jointly planning trains and network maintenance allows for better use of resources. READ MORE

  4. 3. Cost Overrun in Swedish Infrastructure Transport Projects : An Analysis of Cost Overrun in Swedish Infratructure Transport Projects between 2010-2022

    University essay from Jönköping University/IHH, Nationalekonomi

    Author : Edwin Sjögren; Jacob Norgren; [2023]
    Keywords : Cost Overrun; Infrastructure Transport Projects; Swedish Infrastructure; Behavioral Economics; Optimism Bias; Strategic Misrepresentation; Cost Estimation; Forecasting;

    Abstract : Cost Overrun is something that plagues infrastructure projects, both in Sweden and globally. The repercussion of it can be severe since it not only hurts the public’s perception of how the public authorities manage and allocates its resources, but also due to the immense opportunity costs that arise when the increased costs need to be covered.

  5. 4. Opportunities with Modular Systems in Level Crossings : A Case Study in the Swedish Railway Industry

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Marcus Ankaräng; [2023]
    Keywords : level crossing; railway; modular system; systems engineering; systems development; plankorsning; järnväg; modulsystem; systemteknik; systemutveckling;

    Abstract : Level crossings are a dangerous part of railways, causing several deaths every year. While the safest solution is to remove crossings altogether using bridges or tunnels, this is complicated and cannot be done on a large scale. Many level crossings will therefore continue to exist.

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

    University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesi

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

    Abstract : 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. READ MORE
