  1. 1. Data Driven Anomaly Control Detection for Railway Propulsion Control Systems

    Magister-uppsats, Mälardalens högskola/Inbyggda system; Mälardalens högskola/Inbyggda system

    Författare :Dzenita Skulj; Ajna Hodzic; [2020]
    Nyckelord :;

    Sammanfattning : The popularity of railway transportation has been on the rise over the past decades, as it has been able to provide safe, reliable, and highly available service. The main challenge within this domain is to reduce the costs of preventive maintenance and improve operational efficiency. LÄS MER

  2. 2. Tillståndskontroll av maskiners säkerhet

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Torbjörn Enberg; [2020]
    Nyckelord :Machine safety; validation; documentation; Maskinsäkerhet; validering; dokumentation;

    Sammanfattning : Provning och validering av säkerhetsfunktioner sker regelmässigt när en maskin tas i drift. Provning och validering sker i mindre omfattning senare i en maskins livscykel. Dokumentationen av sådan provning är även den mindre i omfattning senare i livscykeln. LÄS MER

  3. 3. Assessment of on-site wastewater treatment systems in unsewered communities in Jordan

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Hani Yahya Ali Shubail; [2020]
    Nyckelord :Constructed wetland; Decentralized wastewater treatment; Jordan; On-site wastewater treatment system;

    Sammanfattning : Centralized wastewater treatment systems need substantial funds besides high-cost operation and maintenance programs, which could be considered unsuitable for low-income developing countries. As a solution, it becomes the trend towards on-site wastewater treatment systems (OWTs) due to its cost-effectiveness and flexibility of implementation and management. LÄS MER

  4. 4. Wave resource assessment using numerical wave modelling

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Akash Vijay Kumar; [2020]
    Nyckelord :Wave resource assessment; SWAN model; numerical wave modelling;

    Sammanfattning : Wave resource assessment is the collection of site-specific meteorological data to estimate the wave potential in a region and is carried out to mitigate the risks involved in the setup of wave energy converters. Wave resource assessment has been typically done using wave buoys. LÄS MER

  5. 5. A Machine Learning-Based Approach for Fault Detection of Railway Track and its Components

    Master-uppsats, Luleå tekniska universitet/Drift, underhåll och akustik

    Författare :Johnny Asber; [2020]
    Nyckelord :Condition Based Maintenance in Railway; Machine Learning; Deep Learning; ResNet-50;

    Sammanfattning : The hard equation of railway safety versus the high commercial profits can only be achieved through the use of new inspection methods supported by modern technologies. The track and its components can have different types of troubles, such as rail surface defects, broken sleepers, missing fasteners, and irregular ballast levels. LÄS MER
