  1. 1. 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heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance.

  3. 2. 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

  4. 3. Anomaly Vibration Classification for Condition Monitoring in Passenger Cars

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Rui Zhou; [2023]
    Keywords : ;

    Abstract : This research aims to investigate accurate classification of anomalous vibrations produced during vehicle operation. The main research questions are which data can be used as classification criteria, which models can better achieve classification effects, and how to address classification issues under different variables in a car.

  5. 4. Development of a model-free damage detection algorithm using AR-models and its application to a riveted steel railway bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Mattis Johannes Frenz; [2022]
    Keywords : ;

    Abstract : Bridges are one of the most important structures in our infrastructural system today.The modern society depends on these structures which in majority are nearingthe end of their design life. Therefore, the need for monitoring of bridges is increasing. READ MORE

  6. 5. Detection of performance anomalies through Process Mining

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Carmine Marra; [2022]
    Keywords : Process mining; Conformance Checking; performance anomalies; ERTMS ETCS; Railway system; complex computer systems.;

    Abstract : Anomaly detection in computer systems operating within complex environments,such as cyber-physical systems (CPS), has become increasingly popularduring these last years due to useful insights this process can provide aboutcomputer systems’ health conditions against known reference nominal states.As performance anomalies lead degraded service delivery, and, eventually,system-wide failures, promptly detecting such anomalies may trigger timelyrecovery responses.
