  1. 1. Genetic consequences of translocations in the Doñana population of the endangered Iberian lynx

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Gaia Mora; [2024]
    Nyckelord :Conservation Genetics; Iberian lynx conservation; endangered species; species conservation;

    Sammanfattning : Conservation genetics for endangered species is crucial in long-term conservation actions.Inbreeding depression and genetic diversity are main genetic parameters with relevance toconservation. The Iberian lynx was by 2002 the most endangered felid in the world. LÄS MER

  3. 2. The quest for a classical bulge - a study of kinematics, abundances, and ages using microlensed dwarf stars and Gaia

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

    Författare :Calum Kvernes Macpherson; [2023]
    Nyckelord :Bulge; Milky Way; Kinematics; Galpy; Dwarf Stars; Physics and Astronomy;

    Sammanfattning : Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter.

  4. 3. Finding new members of the VelHel-4 stream

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

    Författare :Lucas Johansson; [2023]
    Nyckelord :Galactic Archaeology; Milky Way; Stellar Streams; Streams; Stellar Halo; Stars; Globular Cluster; Astronomy; Astrophysics; Gaia; Chemical Abundance; Spectroscopy;

    Sammanfattning : According to the paradigm of lambda-CDM cosmology, the stellar halo ofour Galaxy has been built-up over time through the accretion of other galaxiesand star clusters. The remnants of some of these are still observable today asstellar streams, but are typically very faint and difficult to resolve amidst the farmore numerous foreground Milky Way stars. LÄS MER

  5. 4. Anomaly Detection for Network Traffic in a Resource Constrained Environment

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Pontus Lidholm; Gaia Ingletto; [2023]
    Nyckelord :Network Traffic; Anomaly Detection; Embedded Systems; Machine Learning; Random Forest;

    Sammanfattning : Networks connected to the internet are under a constant threat of attacks. To protect against such threats, new techniques utilising already connected hardware have in this thesis been proven to be a viable solution. LÄS MER

  7. 5. The tangled Warp of the Milky Way

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

    Författare :Viktor Hrannar Jónsson; [2023]
    Nyckelord :Galaxy: structure; Galaxy: kinematics and dynamics; Galaxy: disk; Galaxy: evolution; Physics and Astronomy;

    Sammanfattning : Context: The Milky Way disc, like the discs of many other spiral galaxies, has been shown to be warped. The growing astrometric data set for stars produced by the Gaia mission allows for more detailed studies of the stellar disc's warp. LÄS MER
