  1. 1. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Erik Fridén; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. LÄS MER

  3. 2. Determination of a hydropower "go-to area" : Klarälven and Dalälven potential assessment and environmental regulation constraints

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

    Författare :Paula Aparicio Garcia; [2023]
    Nyckelord :Hydropower; REPowerEU; Go-to areas; GIS; MCDA; AHP; RED II; WFD; Nature 2000; Vattenkraft; REPowerEU-Planen; Go-to area; GIS; MCDA; AHP RED II; WFD; Nature 2000;

    Sammanfattning : The current energy crisis with sky-rocketed prices has created the need for new sustainable solutions in the energy production sector. The REPowerEU Plan, presented by the European Commission, has taken up on this and has established measures to accelerate the introduction of new renewable energy capacity in Europe, such as the designation of “go-to areas” by Member States to shorten authorization permits in areas with high potential and low environmental impacts.

  4. 3. Neutrino Hotspots in the Universe: a Sensitivity Study Using the IceCube Neutrino Observatory

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Kiana Ghiassi; Julia Salwén; [2023]
    Nyckelord :Astrophysics; Neutrino Astronomy; Particle Physics; Neutrinos; Blazars; Sensitivity Study; IceCube Neutrino Obesvatory;

    Sammanfattning : In this report, we aim to assess the sensitivity and 5$\sigma$ discovery potential of IceCube, the largest neutrino observatory on Earth, and compare it with prior findings. Our thesis will focus on a point source analysis, exploring the energy and declination dependencies, with particular emphasis on high-energy neutrinos. LÄS MER

  5. 4. Development of a Low Noise Drone Propeller Using CFD Simulations

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Axel Schulz; [2023]
    Nyckelord :Drone Propeller Low Noise Computational Fluid Dynamics CFD; Technology and Engineering;

    Sammanfattning : Noise pollution generated by drones has in recent years become a concern for humans and wildlife and has in some regions resulted in regulatory backlash. This thesis investigates the possibilities of developing a low noise drone propeller using computational fluid dynamics (CFD) simulations. LÄS MER

  7. 5. Evaluation of a Minute Synthesis Irradiation Model for the Frequency Containment Reserve : Disturbance down-regulation market

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Pablo Omar Luz Pedemonte; [2022]
    Nyckelord :Solar Energy; Photovoltaic; Irradiance variability; Synthetic solar irradiance; Ancillary services; Frequency regulation; Balancing market;

    Sammanfattning : With the increase in energy demand, and therefore, in energy generation, new high voltage direct current export links and overseas connections of large amounts of power are being introduced. These new links are subject to possible malfunction or failures, which may causea substantial frequency increase in the power system. LÄS MER
