  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

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Erik Nordlund; [2023]
    Nyckelord :Inductive switch point heating; Turnout heating; railway turnout heating; Inductive heating;

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heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance.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

  3. 2. Brobanor och dess egenskaper för kommande höghastighetsjärnväg : Brobanors användning och egenskaper i samband med höghastighetsjärnväg

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Haris Zubanovic; Hajk Saakyan; [2023]
    Nyckelord :Bridge lanes; cost; high-speed railway; maintenance; precast bridge elements; Brobanor; höghastighetsjärnväg; kostnad; underhåll; prefabricerade broelement;

    Sammanfattning : SammanfattningSvensk järnväg har aldrig varit mer belastad och trafikerad än idag, och värre kommer det att bli. Det har inte pågått några större investeringar i svensk järnväg sen 1990-talet, effekterna av den strategin börjar bli alltmer uppenbar. LÄS MER

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

    Master-uppsats, KTH/Lantmäteri – fastighetsvetenskap och geodesi

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Rui Zhou; [2023]
    Nyckelord :;

    Sammanfattning : 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.

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

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Mattis Johannes Frenz; [2022]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
