  1. 1. Causes for Single Accidents Among Pedestrians

    Master-uppsats, KTH/Transportplanering

    Författare :Alba Lunner; Siri Norling; [2023]
    Nyckelord :Pedestrian; Single accident; Fall accident;

    Sammanfattning : In the traffic environment, pedestrians account for approximately one thirdof injured road users. The vast majority (95%) are single accidents, i.e.,pedestrian falls without any another part involved. LÄS MER

  3. 2. How can the Cost Competitiveness of an Electric Bus Contribute to a Bus Operator's Investment Decision?

    Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.)

    Författare :Javid Ishaq Ali; [2023]
    Nyckelord :Electric bus; Total cost of ownership; Public transport; Elektrisk buss; Total ägarkostnad; Kollektivtrafik;

    Sammanfattning : The study explores how a bus operator can utilize cost-effectiveness when transitioning from conventional to electric buses. An operator with significant investments in traditional buses expects them to operate for several years to get the expected return. LÄS MER

  4. 3. Exploring the feasibility of resellers in the battery diagnostics industry

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mariel Alkindar Soares; [2023]
    Nyckelord :Energy Storage; Business model; Battery Diagnostics; Reseller model; Energilagring; Affärsmodell; Batteridiagnostik; Återförsäljarmodell;

    Sammanfattning : One of the most important sources of the world development is energy and Battery energy storage systems (BESS) have emerged as crucial components in transitioning from conventional energy systems to more sustainable and environmentally friendly alternatives. Despite BESS’s importance, the dissemination of knowledge about how this technology function has not kept pace with its market development. LÄS MER

  5. 4. Prognostics for Condition Based Maintenance of Electrical Control Units Using On-Board Sensors and Machine Learning

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Gabriel Fredriksson; [2022]
    Nyckelord :machine learning; random forest; random survival forest; condition based maintenance; cbm; reliability; solder joint failure; thermomechanical cycling; ECU; lifetime prediction; data-driven; statistics; BGA; PCBA; field quality; maintenance; truck; bus; vehicle;

    Sammanfattning : In this thesis it has been studied how operational and workshop data can be used to improve the handling of field quality (FQ) issues for electronic units. This was done by analysing how failure rates can be predicted, how failure mechanisms can be detected and how data-based lifetime models could be developed. LÄS MER

  7. 5. Condition Based Reliability Evaluation and Maintenance Strategy for Battery Energy Storage System

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

    Författare :Novalie Hou; [2022]
    Nyckelord :Battery Energy Storage System; Reliability Evaluation; Maintenance Strategy; Batterienergilagringssystem; Tillförlitlighets Evaluering; Underhållsstrategi;

    Sammanfattning : The electrical grid balances production capacity and demand in real-time. With an increased demand for renewable energy sources, challenges such as stability of the grid, the balance between generation and demand, and power quality occur. LÄS MER
