  1. 1. Påverkan av beståndsföryngringen på markberedningsresultatet vid högläggning och harvning i Norrbotten

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Jacob Sundström; [2021]
    Keywords : markbehandling; underväxtröjning; markberedningspunkt; planteringspunkt; hyggesrensning; underväxt; terräng;

    Abstract : I Sverige är maskinell markberedning den dominerande skogsvårdsåtgärden efter avverkning. Markberedning är en bearbetning av marken som görs för att skapa en gynnsam växtplats för kommande föryngring. READ MORE

  3. 2. Analysis of AEP prediction against production data of commercial wind turbines in Sweden

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Aromal Sugathan; Sean Gregory; [2021]
    Keywords : Energy assessment; validation; wind power; Sweden; P50; AEP; WCP;

    Abstract : Based on data from 2083 wind turbines installed in Sweden since 1988, the annual energy production (AEP) predictions considered at the project planning phases of the wind turbines in Sweden have been compared to the wind-index-corrected production data. The production data and the predicted AEP data are taken from Vindstat, a database that collects information directly from wind turbine owners in Sweden. READ MORE

  4. 3. Topographic controls of drought impact on Swedish primary forests

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Johanna Asch; [2021]
    Keywords : Physical geography; ecosystem analysis; primary forest; boreal forest; drought impact; topography; drainage; climate change; random forest; terrain index; Earth and Environmental Sciences;

    Abstract : Anthropogenic climate change has increased the frequency of extreme drought events and leads to “hotter” droughts. Topography controls plant available water and site-specific climatic conditions. Drought sensitivity may therefore vary over short distances between wet and dry locations of the landscape. READ MORE

  5. 4. Addressing intersection artifacts on textured, geometrically rendered vector data in 3D applications

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

    Author : Bjarni Ragnar Gudmundsson; [2019]
    Keywords : ;

    Abstract : There exist various methods to render vector data in 3D applications. One such method is to render the data geometrically, where polyline data is tessellated into some geometry that is rendered on top of the 3D terrain. READ MORE

  6. 5. Propagation of Radio Waves in a Realistic Environment using a Parabolic Equation Approach

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Jonas Ehn; [2019]
    Keywords : Electromagnetic fields; wave propagation; radar; parabolic equation; split-step Fourier method;

    Abstract : Radars are used for range estimation of distant objects. They operate on the principle of sending electromagnetic pulses that are reflected off a target. This leads to the propagation of electromagnetic waves over large distances. As the waves propagate, they are affected by several aspects that decrease the performance of the radar system. READ MORE
