  1. 16. Deep Feature UAV Localization in Urban Areas and Agricultural Fields and Forests

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

    Author : Markus Mäkelä; [2021]
    Keywords : UAV Localization; Deep Learning; Lucas-Kanade; Absolute Localization; Visual localization; UAV lokalisering; Djupinlärning; Lucas-Kanade; Absolut lokalisering; Visuell lokalisering;

    Abstract : The reliance on GPS for Unmanned Aerial Vehicle (UAV) localization limits the areas of application to places with a stable GPS signal. The emergence of deep learning in computer vision has made deep learning methods for visual UAV navigation a promising candidate for autonomous GPS denied localization. READ MORE

  3. 17. Deep Learning for Earth Observation: improvement of classification methods for land cover mapping : Semantic segmentation of satellite image time series

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

    Author : Benjamin Carpentier; [2021]
    Keywords : Satellite Image Time Series; Remote sensing; Land Cover Classification; Deep Learning; Convolutional Neural Network; Tidsserier av satellitbilder; Fjärranalys; Classificering; Djupinlärning; KonvolutionelltNeuralt Nätverk;

    Abstract : Satellite Image Time Series (SITS) are becoming available at high spatial, spectral and temporal resolutions across the globe by the latest remote sensing sensors. These series of images can be highly valuable when exploited by classification systems to produce frequently updated and accurate land cover maps. READ MORE

  4. 18. Observing stellar streams made in a supercomputer

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Erik Fridén; [2021]
    Keywords : Physics and Astronomy;

    Abstract : Stellar streams are made of stars that originate from globular clusters or dwarf satellite galaxies that have been disturbed by the gravitational pull from the galaxy they orbit. These stellar streams hold information about the history of the progenitor as well as information about the gravitational potential of the host galaxy. READ MORE

  5. 19. FORESAIL-2 AOCS Trade Studies and Design

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Guillaume Le Bonhomme; [2020]
    Keywords : space engineering; CubeSat; ADCS; AOCS; spacecraft subystems; nanosatellite;

    Abstract : This thesis aims to design a reliable CubeSat platform, including the avionic subsystems that can sustain a high radiation environment for a mission having a lifetime of at least six months. The science instruments put stringent requirements on the platform to achieve and maintain the desired spin rate. READ MORE

  6. 20. A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julika Wolf; [2020]
    Keywords : Physical Geography and Ecosystem Analysis; drought impacts; old-growth forests; forest management; remote sensing; Earth and Environmental Sciences;

    Abstract : Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. READ MORE
