  1. 1. Flexible project management in highly regulated railway signaling projects

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

    Författare :Teresa Talio; [2023]
    Nyckelord :Signalling; Railway; System development; Systems Engineering; Lean Philosophy; Stage-Gate Process; Signalering; järnväg; systemutveckling; systemteknik; Lean-filosofi; Stage-gate-processen;

    Sammanfattning : Railway is a complex system, with many components that are linked with one another. If a failure occurs in a sub-system, it can affect the functionality and the safety of the whole. Signalling represents a crucial component of the railway system because it ensures safety, and it can optimize capacity on the lines. LÄS MER

  3. 2. Development and Analysis of Small Signal DQ-Frame Model for Low Frequency Stability of Train Converters

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

    Nyckelord :Low Frequency stability; DQ-frame modeling; Single phase converter; Electric rail way systems; Lågfrekvent stabilitet; DQ-ram modellering; Enfasig likriktare; Elektriska järnvägssystem;

    Sammanfattning : In order to meet the increasing demand for sustainable transportation, trains need to run with tighter schedules, more departures and more trains in depot. Multiple trains in depot has been linked to low frequency instability at many locations around the world. LÄS MER

  4. 3. Calibration and preparation of the data analysis of the DORN experiment on board the Chang'E 6 lunar mission.

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Íñigo de Loyola Chacartegui Rojo; [2023]
    Nyckelord :Radon; lunar mission; alpha spectrometry; space instrumentation; performance testing and validation;

    Sammanfattning : As part of the first agreement between the French (CNES) and the Chinese (CNSA) space agencies in terms of space exploration, the DORN instrument will fly on board the Chinese Chang'E 6 mission in 2024. It aims to measure the amount of Radon escaping from the lunar soil to better understand what governs the concentration of this noble gas which contributes to the endogenous origin of the lunar exosphere.

  5. 4. On the road to grid stability - Using batteries in heavy vehicles and charging infrastructure as frequency reserves

    Master-uppsats, Lunds universitet/Produktionsekonomi

    Författare :Matilda Kjellström; Caroline Wuttke; [2023]
    Nyckelord :Case Study; Electrification; Frequency regulation; Energy reserve; Battery; Heavy vehicles; Vehicle-to-grid; Technology and Engineering;

    Sammanfattning : Background: Climate change and increasing threats that come with it fosters a need for changing from fossil sources of energy to renewable ones. Sweden aims to have net zero greenhouse gas emissions by the year of 2045. One of the sectors that need to take part in this shift towards fossil free energy is the transport industry. LÄS MER

  7. 5. Improving charging scheduling of public transport electric buses

    Master-uppsats, Lunds universitet/Produktionsekonomi

    Författare :Franz Bamberg; Anna Hassler; [2023]
    Nyckelord :Peak load; electricity trading; spot prices; electric buses; bus transport operator; battery energy storage system; charging scheduling; Technology and Engineering;

    Sammanfattning : Title: Improving charging scheduling of public transport electric buses Authors: Anna Hassler & Franz Bamberg Supervisor: Johan Marklund, Lund University Background: This thesis focuses on a Swedish BTO that operates EB fleets. For companies investing in electrification, record-high and volatile electricity prices, present challenges and creates a need to improve the charging scheduling of EBs to reduce costs. LÄS MER
