  1. 1. Chariots of the Atlantic Warriors - A Comparative Study of Chariot Motifs on Scandinavian and Iberian Rock Art


    Författare :Hannes Grahn; [2023-03-17]
    Nyckelord :Bronze Age; Rock art; Chariots; Scandinavia; Iberia; Long-distance interaction; Frännarp; Kivik; Villfara; Iberian warrior stele;

    Sammanfattning : During the last two decades, ideas of long-distance interaction between cultures has gained an increased amount of attention in the field of Bronze Age research. Previous research has shown that such a long-distance interaction, connected to the trade of metal and amber, may have existed between Scandinavia and Iberia, facilitated by a group of seafaring warrior-traders, with a shared identity, set of values and cosmology.

  2. 2. Forming wide-orbit planets via pebble accretion

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

    Författare :Nerea Gurrutxaga; [2023]
    Nyckelord :Planet Formation; Pebble Accretion; Protoplanetary Disk; Wide-Orbit Planet; Physics and Astronomy;

    Sammanfattning : The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. LÄS MER

  3. 3. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Alexandros Bampis; [2023]
    Nyckelord :Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Sammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER

  5. 5. Detection and location of HVDC commutation faults from PMU data

    Master-uppsats, Lunds universitet/Industriell elektroteknik och automation

    Författare :Alejandro Belinchon Calderon; [2018]
    Nyckelord :HVDC-links; HVDC converters; Commutation failures; Phasor measurement units PMUs ; Electric power systems; Wide Area Measurement systems WAMS ; Standard IEEEC 37.118; Single-line to ground faults; Three-Phase faults; Fault detection and location; Nordic 32; DigSilent-PowerFactory; PSCAD; MATLAB-Simulink; Symmetrical components.; Technology and Engineering;

    Sammanfattning : Commutation Failures in LCC HVDC converters is a topic that is normally addressed from the component perspective, looking at converters’ internal signals. How these commutation failures affect the outer AC network is not deeply understood yet. LÄS MER
