  1. 1. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

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

    Författare :Carl Holmquist; [2023]
    Nyckelord :Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

    Sammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER

  3. 2. Heart- and Sapwood Segmentation on Hyperspectral Images using Deep Learning

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Samuel Hallin; Simon Samnegård; [2023]
    Nyckelord :Computer Vision; Hyperspectral Imaging; Heartwood; Sapwood; Deep Learning; Segmentation; Dimensionality Reduction; PCA; PLS; SVM; U-NET; U-within-U-Net;

    Sammanfattning : For manufacturers in the wood industry, an important way to make the production more effective is to automate the process of detecting defects and different attributes on boards. One important attribute on most boards is heartwood and sapwood. LÄS MER

  4. 3. Endophytic fungi in living trees - are communities affected more by tree species, tree age, or geographic origin?

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Lisen Källman; [2022-08-16]
    Nyckelord :;

    Sammanfattning : Endophytic fungi are ubiquitous in living vascular plants and have been identified in most terrestrial environments. The endophytes may have various ecological roles such as commensals, symbionts and latent invaders. LÄS MER

  5. 4. Water mapping in Scots pine stands after thinning

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Michalina Maria Grabowska; [2022]
    Nyckelord :Scots pine; Pinus sylvestris; drought; thinning; root system; water uptake; heavy water;

    Sammanfattning : Climate change is an ongoing issue in various fields, including forestry. More frequent and severe droughts have been already noted around the world, also in Europe. Visible reduction in available water in forests has adverse consequences such as increased tree mortality, higher vulnerability and smaller growth. LÄS MER

  7. 5. Design av testanläggning för förbränning av pellets i matlagningsspisar : Analys av hur pelletsens egenskaper påverkar emissioner och effektivitet under förbränning

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Nellie Dalqvist; [2022]
    Nyckelord :Pellets; askhalt; extraktivämnen;

    Sammanfattning : Renewable energy sources have dominated energy use throughout human history and biomass is one of the world's oldest energy sources. The use of biomass as a fuel has increased in recent decades and has led to great technological development as a result of the growing demands for sustainable solutions. LÄS MER
