  1. 1. Claws and Effect : how Small Carnivore Richness Responds to Habitat Diversity and Ecological Productivity

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Emilia Arkdalen; [2023]
    Keywords : small carnivore; camera trap; occupancy model; species richness; productivity; habitat richness; habitat evenness;

    Abstract : Species distribution and composition research has gained significance in light of global warming and its impact on biodiversity. Understanding the factors shaping species richness is crucial for wildlife ecology and conservation. READ MORE

  2. 2. Multi-scale Bark Beetle Predictions Using Machine Learning

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Albert Øhrman Wellendorf; [2023]
    Keywords : Geography; GIS; Geographically weighted regression; bark beetle; machine learning; Earth and Environmental Sciences;

    Abstract : Bark beetle attacks have led to widespread tree disturbance and deaths in many parts of the world, and thereby also economic and biodiversity losses. Forest-rich Sweden has experienced periodic attacks, latest in 2018. READ MORE

  3. 3. Groundwater Inflow into Fractured Rock Tunnels

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Mariam Beydoun; [2022]
    Keywords : groundwater inflow; rock tunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynold’s equation; cubic law; grundvatteninflöde; bergtunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynolds equation; cubic law;

    Abstract : Groundwater inflow is a challenge in construction of tunnels in fractured bedrocks since it affects the safety function of tunnels and leads to potential problems in the surrounding environment, such as subsidence, dropdown of the groundwater table. Quantification of groundwater inflow into the tunnel is also important for design of grouting in the construction of the tunnel. READ MORE

  4. 4. Modelling solar access at the window level of buildings – a case study for urban densification simulations in Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Kendall Hartman; [2021]
    Keywords : Physical Geography and Ecosystem analysis; CityJSON; 3D City Model; solar energy; solar urban planning; sustainable urban development; NS building; Geomatics; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : Buildings are a are a major consumer of energy in urban areas. The use of solar energy in buildings can help reduce CO2 emitting energy consumption in these urban areas. One way to use solar energy is through passive solar energy systems. Passive solar energy systems allow a building to use daylight as an energy source. READ MORE

  5. 5. Analysis of Hall effect thrusters using Hybrid PIC simulations and coupling to EP plume

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : David Villegas Prados; [2020]
    Keywords : Hallis; SPIS; EP; plume; hybrid PIC; Hall effect; HET; inside channel; plume expansion;

    Abstract : In the last 30 years, numerical models have been developed to properly analyze Hall eect thrusters (HET),leading to a bridge between analytical prediction/empirical intuition and experiments. For companies in thespace sector, these codes serve to much more than simply simulating the thruster, but it provides a fast, cheapand reliable tool for processes such as validation and verication procedures, as well as for technical developmentof the thruster.
