  1. 1. Hyperspectral and multispectral satellite data analysis of nitrogen in grazed and ungrazed tundra in Långfjället, Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Emma Dahlstedt; [2023-08-18]
    Keywords : Hyperspectral imaging; Imaging spectroscopy; Nitrogen; Reindeer; Herbivory; Tundra; Grazing;

    Abstract : Reindeer are a keystone species in the circumpolar north, where they hold great cultural and ecological importance. Continued climate change threatens the long-term sustainability of reindeer husbandry. Reindeer can affect the tundra landscape, influencing the soil nutrient cycling, including the soil nitrogen availability. READ MORE

  3. 2. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Jessica McKenna; [2023]
    Keywords : Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Abstract : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

  4. 3. Microsatellite Constellation for Wildfire Monitoring

    University essay from KTH/Geoinformatik

    Author : Citlali Bruce Rosete; [2022]
    Keywords : microsatellite; shortwave infrared sensor; active fire monitoring; burned area detection; satellite constellation; mikrosatellit; kortvågig infraröd sensor; aktiv brandövervakning; detektion av brandhärjat område; satellitkonstellation;

    Abstract : I flera års tid har antalet svåra och okontrollerade skogsbränder ökat i antal. Det finns ett behov av att detektera skogsbränder med hjälp av satelliter som har högre tidsupplösning samt högre geometrisk upplösning än de satelliter som är i bruk idag. READ MORE

  5. 4. Exploring Diversity of Spectral Data in Cloud Detection with Machine Learning Methods : Contribution of Near Infrared band in improving cloud detection in winter images

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nakita Sunil Oza; [2022]
    Keywords : Remote sensing; Multispectral imaging; Cloud detection; Data diversity; Deep learning; Fjärranalys; Multispektral bildbehandling; Molndetektion; Datadiversitet; Djupinlärning;

    Abstract : Cloud detection on satellite imagery is an essential pre-processing step for several remote sensing applications. In general, machine learning based methods for cloud detection perform well, especially the ones based on deep learning as they consider both spatial and spectral features of the input image.

  6. 5. The magnetic field of phi Draconis

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Nikolaos Papakonstantinou; [2022]
    Keywords : stars: atmospheres – stars: chemically peculiar – stars: magnetic field – stars: starspots – stars: individual: phi Dra;

    Abstract : Within this past decade, advances in spectropolarimetric analyses allowed mapping surface characteristics of nearby non-resolved stars with unique characteristics. In this study, we attempt mapping of the magnetic field structure and surface distribution of elements for such a star, the magnetic Ap star phi Dra. READ MORE
