  1. 21. Utilising Raw GNSS Data from Android Units to Improve Positioning

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Karin Seifert; [2022]
    Nyckelord :;

    Sammanfattning : In this study it was examined if positioning can be improved by utilising raw Global Navigation Satellite System (GNSS) data from Android devices instead of using Android's existing Location API. If this is the case, the coworkers at BM System may modify their apps, one is called Loco, to develop one that calculates positions directly by utilising raw GNSS data instead of using Android's Location API which is done presently.

  3. 22. Importance of Snow in Alpine Plant Ecology : And Remote Sensing Applications in Species Modeling

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Eva Meyer; [2022]
    Nyckelord :;

    Sammanfattning : Global warming, with pronounced increases toward the poles and high latitudes, has impacts on alpine vegetation. If snow patterns change in response to global warming, snow parameters are predictors of interest in alpine plant species distribution and traits modeling because snow is known to strongly control the local growing conditions of alpine plants.

  4. 23. Tidig detektering avgranbarkborreangrepp med hjälp avfjärranalys via Sentinel-2

    Kandidat-uppsats, Högskolan i Gävle/Datavetenskap

    Författare :Najm Eddin Eid; Petter Jakobsson; [2022]
    Nyckelord :Remote sensing; Sentinel-2; spruce bark beetle; spruce forest; vegetation analysis; vegetation index; band combinations; image analysis.; Fjärranalys; Sentinel-2; granbarkborre; granskog; vegetationsanalys; vegetationsindex; bandkombinationer; bildanalys.;

    Sammanfattning : Granbarkborre är en av Sveriges mest destruktiva skadeinsekter som angriper granskog. Insekten har medfört förödande konsekvenser för granskog, framför allt sedan2018 där stora arealer granskog nästan har eliminerats. Insekten trivs i varmt ochtorrt klimat. LÄS MER

  5. 24. Localization of Combat Aircraft at High Altitude using Visual Odometry

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Jenny Nilsson Boij; [2022]
    Nyckelord :Monocular Visual Odometry; Monocular SLAM; High Altitude; Combat Aircraft; X-Plane;

    Sammanfattning : Most of the navigation systems used in today’s aircraft rely on Global Navigation Satellite Systems (GNSS). However, GNSS is not fully reliable. For example, it can be jammed by attacks on the space or ground segments of the system or denied at inaccessible areas. LÄS MER

  7. 25. Determination of semi-aerobic landfill suitability in tropical developing countries using land surface temperature : A case study of an unmanaged open dump in transition in Yangon City region, Myanmar

    Master-uppsats, Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

    Författare :Václav Pánek; [2022]
    Nyckelord :;

    Sammanfattning : Population growth rate increases rapidly, which reflects on Municipal Solid Waste(MSW) generation rates and the accumulation in unmanaged open dumps and landfills in developing countries. Consequences of improper MSW management and treatment are not only local or regional but global since Methane (CH4) emissions are responsible for a notable part of the total anthropogenic CH4 emissions.
