  1. 1. Förläggning och utsättning av kabel längs Sveriges järnvägar

    Uppsats för yrkesexamina på grundnivå, Lunds universitet/Trafik och väg

    Författare :Henric Hagström; [2023]
    Nyckelord :Järnväg; Kabelförläggning; Kabelskada; Kabelanvisning; Underhåll; Förvaltning; Railway; Cable placement; Cable damage; Cable exposure; Maintenance; Management; Technology and Engineering;

    Sammanfattning : Detta examensarbete handlar om de problem relaterade till kabelskador som uppstår idag i samband med kabelutsättning vid grävarbeten inom järnväg. Kabelutsättning utförs vanligtvis av en underhållsentreprenör, som utförs genom att markera markytan där kabel under marken kan tänkas finnas. LÄS MER

  3. 2. Modeling and Simulation of a Planar Unmanned Aerial Manipulator

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Brynja Þorsteinsdóttir; [2023]
    Nyckelord :Unmanned Aerial Manipulator; Cable Driven Parallel Manipulator; Unmanned Aerial Vehicle; Dynamics; Simulation; Obemannad Flygande Manipulator; Kabeldriven Parallellmanipulator; Obemannad Flygande Farkost; Dynamik; Simulering.;

    Sammanfattning : A unique Unmanned Aerial Manipulator (UAM), also termed an aerial robot, is the subject of this thesis. A UAM is composed of a floating base attached to a manipulator that enables it to interact physically with the environment. LÄS MER

  4. 3. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Eduardo Garcia Cañas; [2022]
    Nyckelord :HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

    Sammanfattning : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. LÄS MER

  5. 4. Model-Based Fault Diagnosis of an Electrical Low-Voltage Grid

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Johan Lindström; [2021]
    Nyckelord :fault; diagnosis; low-voltage; grid; model-based;

    Sammanfattning : Reliable access to power is essential for modern society’s fundamental functions. It is necessary that faults and abnormalities in low-voltage grids can easily be detected and diagnosed. A fault in a grid can be a consequence of several causes, including internal damage, technical errors, malfunctioning electricity meters and electricity theft. LÄS MER

  7. 5. CABLES DECOMMISSIONING IN OFFSHORE WIND FARMS: ENVIRONMENTAL AND ECONOMICAL PERSPECTIVE

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Omer Al-Sallami; [2021]
    Nyckelord :Offshore wind energy; subsea cables; decommissioning;

    Sammanfattning : Addressing the decommissioning issues is vital to ensure a sustainable and effective process of such an essential part of the project life cycle. While there is a set of good practices and regulations that govern most of the decommissioning activities, the cable decommissioning issue is still in a big debate and often left abandoned at the seabed due to environmental concerns, as justified by most developers.
