1. 11. 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. 12. A comparison of thinning programmes in European beech (Fagus sylvatica L.) based on permanent plots in Southern Sweden

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Delphine Anni Fortu; [2023]
   Nyckelord :beech; volume growth; diameter development; thinning programme; quality traits;

   Sammanfattning : The present study investigated 7 thinning experiments in beech which were established in 1971. The purpose was to compare two thinning programmes with different thinning intervals. The programmes (A and B) were designed according to yield tables by Carbonnier (1971). The experimental plots have been measured regularly in 5 to 10 years intervals. LÄS MER

4. 13. Mixed Stand vs Monoculture : a Simulation Study Assessing Growth and Profitability of Norway spruce and Birch in Mixtures and Pure Stands

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Babatunde Dosumu; [2022]
   Nyckelord :N.spruce-birch stands; monoculture; thinning treatment; mixed forest;

   Sammanfattning : Picea abies L. Karst (N. spruce) monocultures dominate the forest landscape of southern Sweden due to their suitability for the prevalent site conditions, well established silviculture, and profitability. However, disturbances such as windthrow, bark beetle damage, and Heterobasidion root rot pose a risk to N. LÄS MER

5. 14. Echo of the Ancients: Evolution of Song in the Avian Family Cettiidae

   Master-uppsats, Uppsala universitet/Paleobiologi

   Författare :Jared Goodstadt; [2022]
   Nyckelord :Cettiidae; song; acoustic analysis; PCA; Mahalanobis distance; phylogeny;

   Sammanfattning : The Cettiidae, a family of primarily small, insectivorous, Asiatic and Austronesian, mountain birds have been the subject of acoustic analysis in the past. However, until this point, an in-depth review of the songs of the entire family had yet to be undertaken. LÄS MER

7. 15. Genetic Algorithms for optimizing behavior trees in air combat

   Master-uppsats, Linköpings universitet/Artificiell intelligens och integrerade datorsystem

   Författare :David Ångström; [2022]
   Nyckelord :Genetic Algorithm; Behavior Tree; Behavior Model; Simulation; Optimization;

   Sammanfattning : Modelling and simulating entities in virtual environments are tools commonly used by companies to test, validate and verify their products in close to real scenarios; effectivelyreducing the cost, time and effort compared to real life testing. This is especially the case in the area of air combat where realistic behaviors are not only a necessity, but paramount to replace the costs of fuel and operation time. LÄS MER
