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

   University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesi

   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

4. 3. Enhancing circular economy through circular public procurement : A case study within the Swedish railway industry

   University essay from Luleå tekniska universitet/Industriell ekonomi

   Author : Josefin Odelstam; Josefine Blomqvist; [2023]
   Keywords : Circular economy; circular public procurement; circular requirements;

   Abstract : Purpose: The study aims to identify essential barriers, enablers, and incentives for including circular requirements in tender specification, to facilitate the transition from linear to circular public procurement within the railway industry, thus enhancing a circular economy. This by answering the following research questions: RQ1: What barriers and enablers for circular public procurement within the railway industry exist, and how can the enablers overcome the barriers to facilitate the transition from linear to circular public procurement to enhance a circular economy? RQ2: How can public procurers be incentivized to undergo a transition from linear to circular public procurement within the railway industry? Method: To fulfill the purpose a qualitative case study has been carried out within the Swedish railway industry, focusing on rail vehicle procurement. READ MORE
