  1. 1. Application of formal verification and validation on modern multi-functional signalling system

    Master-uppsats, KTH/Transportplanering

    Författare :Shamsul Arefin; [2022]
    Nyckelord :;

    Sammanfattning : Demand for rail transport is increasing day by day. Rail is popular in public transport due to punctuality, regularity, and safety. However, we hear daily that rail traffic still has many problems to solve about incidents, near misses, and signal errors. LÄS MER

  3. 2. The Attention of Train Drivers : An experimental study of differences in attention between Automatic Train Control and European Railway Traffic Management System (ERTMS)

    Kandidat-uppsats, Linköpings universitet/Filosofiska fakulteten; Linköpings universitet/Interaktiva och kognitiva system

    Författare :Lisa Bernheim; [2022]
    Nyckelord :The Swedish National Road and Transport Research Institute; ERTMS; visual attention; situation awareness; eye-tracking; Statens väg- och transportforskningsinstitut; ERTMS; visuell uppmärksamhet; situation awareness; eye-tracking;

    Sammanfattning : A European project is gradually replacing the current train control systems to a mutual control system called as the European Railway Traffic Management System (ERTMS). I Sweden they have implemented the new train control system on a few train-lines in the northern part of Sweden. LÄS MER

  4. 3. Utilizing Genetic Algorithm and Machine Learning to Optimize a Control System in Generators : Using a PID controller to damp terminal voltage oscillations

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Fredrik Strand; [2022]
    Nyckelord :AVR; AI; data-driven; GA; SVM; GPR; SVR; Ziegler-Nichols; Z-N;

    Sammanfattning : Hydropower is an important part of renewable power production in Sweden. The voltage stability of the already existing hydropower needs to be improved. One way to do this is by improving the control system that damp terminal voltage oscillations. LÄS MER

  5. 4. An automated unmanned aerial vehicle – structure from motion pipeline to create analysis-ready digital surface models for coastal monitoring

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Maximilian Rafael Huber; [2021]
    Nyckelord :physical geography; ecosystem analysis; geomatics; GIS; UAV; structure-from-motion; machine learning; coastal monitoring; Earth and Environmental Sciences;

    Sammanfattning : Anthropogenic pressure on coastal areas continues to increase, thus intensifying coastal erosion. Coastal monitoring programs are therefore essential to prevent severe ecosystem and economic consequences. Successful coastal monitoring schemes require highly accurate analysis-ready Digital surface models (DSMs) derived using the same workflow. LÄS MER

  7. 5. Roslagsbanan: A capacity comparison between the current ATC system and the implementation of a CBTC system

    Master-uppsats, KTH/Transportplanering

    Författare :Chrysostomos Sofroniou; [2021]
    Nyckelord :Roslagsbanan; CBTC; moving block; fixed block; safe braking curve; capacity; Roslagsbanan; CBTC; rörligt block; fast block; säker bromskurva; kapacitet;

    Sammanfattning : Communications-based train control (CBTC) aims to improve headways in the railway systems while maintaining or even improving safety. By means of the CBTC systems, the exact position of a train is known more accurately than the traditional signalling systems. LÄS MER
