  1. 11. Potassium in the Galactic Bulge - as traced by microlensed dwarf & sub-giant stars

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

    Författare :Lukas Jönsson; [2023]
    Nyckelord :Nucleosynthesis; Galactic Bulge; Potassium; Non-Local-Thermal-Equilibrium; Physics and Astronomy;

    Sammanfattning : During this report the potassium (K) trend in the Galactic Bulge, with respect to metallicity and various α-elements, has been computed and evaluated by a method of line synthesis on the 7698.96 ̊A KI line (7699 KI), where Non-Local-Thermal-Equilibrium (NLTE) effects have been considered.

  3. 12. Nanoparticle synthesis analysis : Program for data visualization and cluster analysis of nanoparticle synthesis protocols

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Emil Juviken Hultman; Jacob Signeul; Lucas Lindborg; Eskil Silfur; [2023]
    Nyckelord :Dataanalysverktyg;

    Sammanfattning : As energy demands rise across the globe, new clean energy solutions must be developed. Peafowl Plasmonics is developing a direct solar harvesting device using plasmonic technology. To expand their business and increase manufacturing scalability, nanoparticle synthesis protocols must be made. LÄS MER

  4. 13. Song Popularity Prediction with Deep Learning : Investigating predictive power of low level audio features

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

    Författare :Gustaf Holst; Jan Niia; [2023]
    Nyckelord :machine learning; deep learning; audio;

    Sammanfattning : Today streaming services are the most popular way to consume music, and with this the field of Music Information Retrieval (MIR) has exploded. Tangy market is a music investment platform and they want to use MIR techniques to estimate the value of not yet released songs. LÄS MER

  5. 14. Performance Analysis of the Uplink of Multi-antenna Systems Operating in Aging Channels

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

    Författare :Prasetyo Putranto; [2023]
    Nyckelord :Channel aging; Pilot spacing; Rayleigh; Rician; Spectral efficiency; Uncrewed aerial vehicles; Kanalåldring; Pilotavstånd; Rayleigh; Rician; Spectral effektivitet; Obemannade flygfordon;

    Sammanfattning : In wireless communications, employing pilot symbols enables to estimate the state of the wireless channel at the expense of decreasing the number of symbols available for transmitting data. Addressing this trade-off is particularly challenging when the channel changes rapidly over time, since channel estimates become obsolete over short transmission periods. LÄS MER

  7. 15. Identification of Vanadium-Binding Ligands in White Wine

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Freja T Trybom; [2023]
    Nyckelord :Vanadium; LD converter slag; wine; food waste; recycling.;

    Sammanfattning : Vanadin är en värdefull metall och kan lakas ur LD (Linz-Donawitz)-slagg med hjälp av vin. Ligander i vinet som lakar vanadin från LD-slagg studerades i denna rapport med mål att identifiera några av deras egenskaper såsom apparent molekylmassa och spektral information. LÄS MER
