  1. 6. Carbon Abundance in the Milky Way Galaxy

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Calum Kvernes Macpherson; [2021]
    Nyckelord :Carbon; Abundance; Milky Way; Chemical Evolution; Physics and Astronomy;

    Sammanfattning : Carbon is the fourth most abundant element after hydrogen, helium and oxygen. It is a product of stellar nucleosynthesis as well as it being an important bio signature for life; this makes the analysis of carbon very fundamental. LÄS MER

  3. 7. Mönstersimulering av kamouflage : Framtagning av metodik för virtuell utvärdering av visuell maskeringsförmåga

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Emma Reihammar; [2020]
    Nyckelord :camouflage assessment; signature management; photo simulation; virtual assessment; kamouflageutvärdering; signaturanpassning; fotosimulering; virtuell utvärdering;

    Sammanfattning : Saab Barracuda utvecklar och tillverkar avancerade kamouflagesystem för skydd mot upptäckt och identifiering genom signaturanpassning. Signaturanpassning är en grundläggande del av taktiska strategin för militära styrkor och uppnås genom att reducera kontrasten mot bakgrunden för ändamålsenliga våglängdsområden inom det elektromagnetiska spektrumet.

  4. 8. Relative vegetation height variation and reflectance of herbaceous-dominated patches in Central Sweden

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Jo Santiago; [2020]
    Nyckelord :vegetation height; reflectance; plant biodiversity; herbaceous vegetation; MSAVI; coefficient of variation of heights; Height Variation Hypothesis;

    Sammanfattning : Semi-natural landscapes are recognized as suitable habitats for different plant species and provide ecosystem services that contribute to increased plant biodiversity. At the stand level, plant biodiversity is influenced by vegetation structure, of which vegetation height is an important parameter. LÄS MER

  5. 9. Assessment of Drone-Borne Multispectral Mapping in the Exploration of Magmatic Ni-Cu Sulphides – an Example from Disko Island, West Greenland

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Ethan Barnes; [2020]
    Nyckelord :mineral exploration; UAV; multispectral sensors; Illukunnguaq dyke; Greenland;

    Sammanfattning : The senseFly eBeePlus fixed-wing drone is a market available UAV compatible with a range of sensors that includes the Parrot Sequoia+ multispectral camera. Commercial applications of the drone predominantly focus on agriculture, environmental management, and engineering applications. LÄS MER

  7. 10. Detecting bark beetle damage with Sentinel-2 multi-temporal data in Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Shuo Yang; [2019]
    Nyckelord :Physical Geography and Ecosystem Analysis; Remote Sensing; Bark Beetle; Insect Detection; Sentinel-2; Forest Health; Maximum Likelihood; Random Forest; Spectral Signature; Vegetation Indices; Earth and Environmental Sciences;

    Sammanfattning : The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. LÄS MER
