  1. 1. Energy in the Transportation System - A comparison of charging infrastructure scenarios

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Judith Lai Jakobsson; [2023]
    Nyckelord :Charging infrastructure; road transport electrification; battery capacity need; electric vehicles; Technology and Engineering;

    Sammanfattning : A functioning charging infrastructure is crucial for achieving full-scale national electrification within the transport sector. The system is likely to consist of different charging technologies, all with the main objective of providing efficient energy replenishment services. LÄS MER

  2. 2. Flow batteries - Impact on fire safety

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Ajay Menon; [2022]
    Nyckelord :Flow battery; Flow battery types; Flow battery risks; Firefighting; Fire risk analysis; Safety hazards in flow batteries; Fire risks in lithium-ion battery; Safety hazard in lithium-ion battery; Application of battery storage systems; Safety reports.; Technology and Engineering;

    Sammanfattning : The need for sustainable renewable energy has been increasing due to the negative impact of non-renewable energy sources. With the unstable and sporadic nature of sustainable renewable energy, flow batteries show immense potential in mitigating these issues. LÄS MER

  3. 3. Reversing the flow of heat in system of initially correlated qubits

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Giovanni Francesco Diotallevi; Peter Samuelsson; Faraj Bakhshinezhad; [2021]
    Nyckelord :Qubits; Cooling; Heat Flow; Physics and Astronomy;

    Sammanfattning : The Second Law of Thermodynamics is considered to be one of the most fundamental and important laws of Physics. Both Clausius and Kelvin reformulated the Second Law as statements concerning the behaviour of two communicating systems, set to interact at different temperatures. LÄS MER

  4. 4. Waste[d] Love[s]_Restor[y]ing Fyli Landfill

    Master-uppsats, KTH/Skolan för arkitektur och samhällsbyggnad (ABE)

    Författare :Vasiliki Zotou; [2020]
    Nyckelord :landfill; waste; restoration; ecologies; fiction;

    Sammanfattning : Current practices of landfill restoration can be characterised as anthropocentric, violent and unsuccessful gestures of purification and control, while they erase traces of planetary history and habitats generated by waste and dirt. The dominant notion of landfill restoration insists on a concept of humans as directors of geo-bio flow who are capable of controlling and reversing the dirty chaos they created. LÄS MER

  5. 5. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

    Magister-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Vidar Flodgren; [2019]
    Nyckelord :GaN; gallium nitride; nanoscience; material science; ultrafast lasers; Yb Laser; Pharos Laser; titanium sapphire laser; device fabrication; lift-off; gold etching; optical-field-induced currents; modelling; matlab; Physics and Astronomy;

    Sammanfattning : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. LÄS MER
