  1. 1. The restoration period : a new era in forestry

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

    Author : Ester Andersson; [2023]
    Keywords : historical forest management; past logging; restoration;

    Abstract : In the last 200 years the boreal forests of Sweden have undergone a dramatic transformation. After a long history of high grading the largest trees foresters grew increasingly concerned about the state of logged over forests. The big question was how to regenerate and increase the productivity of sparse forests. READ MORE

  3. 2. Konsekvensanalyser av skötsel på lågproduktiva torvmarker - Ur ett skogsägarperspektiv

    University essay from SLU/Dept. of Forest Resource Management

    Author : Olof Skoglund; [2023]
    Keywords : Torvmark; skogsskötsel; nuvärdesoptimering; potentiella naturvärden; Heureka;

    Abstract : Sverige består idag av 1,7 miljoner hektar produktiv torvmark. Tall på torvmark finns utspritt i hela landet och växer oftast på lågproducerande torvmarker, där gränsen mellan produktiv torvmark och impediment kan vara svår att dra. READ MORE

  4. 3. Social-Ecological Resilience and Whale Conservation

    University essay from Stockholms universitet/Juridiska institutionen

    Keywords : social-ecological resilience; international law; whale conservation; biodiversity protection;

    Abstract : Whale species face numerous man-made threats, such as pollution, whaling, climate change and whale-watching, that threaten their survival. International environmental law has several regulations in place that aim, either directly or indirectly, at conserving whales. READ MORE

  5. 4. Solving Korteweg-de Vries equations with Discontinuous Galerkin methods

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Markus Hellberg Mediaa; [2023]
    Keywords : Discontinuous Galerkin; Korteweg-de Vries; Conservation Laws; Partial Differential Equations; Numerical methods; Higher order spatial derivative; Heat Equation; Burgers’ Equation; Collocation; Lobatto Gauss Legendre; Stiffness; Nodal Approximation; Finite Volume; Finite Element;

    Abstract : In this thesis the Discontinuous Galerkin approximation performance applied to the Korteweg–de Vries equation is investigated. This equation is nonlinear with a third spatial derivative and can be used for shallow water movement. READ MORE

  6. 5. Jet fragmentation in shaped charges

    University essay from KTH/Matematik (Avd.)

    Author : Joakim Ericson; [2022]
    Keywords : Shaped charges; numerical simulation; jet fragmentation; Riktad sprängverkan; numerisk simulering; strål-fragmentering;

    Abstract : This master thesis treats the numerical simulation of shaped charge jets and its fragmentation process. Shaped charges is a method to concentrate the effect of an explosive charge and penetrate deeply into a target due to a the formation of a jet with great penetration capabilities. READ MORE
