  1. 1. Forest fertilization does not cause any long-term effects on tree growth or vegetation composition

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Yixian Chen; [2023]
    Nyckelord :density; ground vegetation; height; stem radial growth; legacy nitrogen effect; soil total N and C N ratio; tree;

    Sammanfattning : Forest fertilization is considered one of the most effective management options to improve forest productivity. In Fennoscandia, nitrogen (N) fertilization has been practiced for over 50 years and is normally added in the form of granules of NH4NO3 at least 15 years prior to the final harvest. LÄS MER

  3. 2. Vertikala skogar : Varför byggs de inte i Sverige?

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Kinora Yevno; Pernilla Bengtsson; [2021]
    Nyckelord :Vertikala skogar; gröna klimatskal; gröna byggnader; gröna fasader; gröna väggar; gröna tak; miljövänligt; grönytefaktor; urbana värmeöeffekten.;

    Sammanfattning : Världen möter klimatförändringar i allt snabbare takt och Sverige är inget undantag. Detta leder till ökade temperaturer, kraftigare skyfall och mer luftföroreningar, samtidigt som urbaniseringen ökar med allt större befolkning i städerna. LÄS MER

  4. 3. UAV geolocalization in Swedish fields and forests using Deep Learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Andreas Rohlén; [2021]
    Nyckelord :Unmanned Aerial Vehicle; Absolute Localization; Deep Learning; Convolutional Neural Network; Cross-View; Neural Network Interpretation; Obemannad Luftburet Fordon; Absolut Lokalisering; Djupinlärning; Convolutional Neural Network; Kors-Perspektiv; Neural nätverkstolkning;

    Sammanfattning : The ability for unmanned autonomous aerial vehicles (UAV) to localize themselves in an environment is fundamental for them to be able to function, even if they do not have access to a global positioning system. Recently, with the success of deep learning in vision based tasks, there have been some proposed methods for absolute geolocalization using vison based deep learning with satellite and UAV images.

  5. 4. Predicting forest strata from point clouds using geometric deep learning

    Master-uppsats, Jönköping University/JTH, Avdelningen för datavetenskap

    Författare :Simon Arvidsson; Marcus Gullstrand; [2021]
    Nyckelord :Supervised learning; Learning to rank; Point-based models; Shape inference; PointNet; layering; layers; classification; ordingal; regression; forest agency; ranking; SLU; 3D; plots;

    Sammanfattning : Introduction: Number of strata (NoS) is an informative descriptor of forest structure and is therefore useful in forest management. Collection of NoS as well as other forest properties is performed by fieldworkers and could benefit from automation. LÄS MER

  7. 5. Effects of 100 years of drainage on peat properties in a drained peatland forests in northern Sweden

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Mikaela Casselgård; [2020]
    Nyckelord :ash content; biodiversity; bulk density; carbon; climate; compaction; ditch; drainage; greenhouse gas emissions; groundwater level; isotopes; nitrogen; peatland; restoration;

    Sammanfattning : Natural peatlands provide a small but persistent long-term carbon (C) sink. However, within the last century their extent in Sweden has declined by about 1.5-2.0 million hectares due to drainage activities. LÄS MER
