  1. 1. Mängden död ved i värdekärnor i Söderåsens nationalpark

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Gustav Thurell; [2024]
    Keywords : volym död ved; stående död ved; liggande död ved; bokskog; nedbrytningsgrad; värdekärna;

    Abstract : There is a lack of knowledge about the development of the dead wood in former production beech (Fagus sylvatica) forests that have been protected. The present study has been carried out in Söderåsen National Park to compare the distribution of dead wood in relatively unaffected beech forests that have been protected for a long time (A-value cores) and older, previously managed beech forest that has only been protected for 20-30 years (B-value cores).

  3. 2. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Johanna Bergström; [2023-09-15]
    Keywords : Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

    Abstract : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. READ MORE

  4. 3. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

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

    Author : Zhenyu Li; [2023]
    Keywords : mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

    Abstract : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. READ MORE

  5. 4. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

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

    Author : Lukas Jonasson; [2023]
    Keywords : Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

    Abstract : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. READ MORE

  6. 5. Föryngring med hägn : effekten av viltbete på självföryngrad ädellövskog i tre skånska naturreservat

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Håkan Ramberg; Kaj Sjöqvist; [2023]
    Keywords : Bokskog; naturlig föryngring; betesbegärlighet; viltbete; strukturförändring;

    Abstract : Ädellövskogens artsammansättning styrs av flera naturliga processer, en av dessa processer är viltbete. Bete kan leda till att trädslagsfördelningen förändras och att föryngring blir problematiskt, speciellt i områden med stora viltstammar och för de mer betesbegärliga trädarterna. READ MORE
