  1. 11. 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

  3. 12. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Duncan Jones; [2023]
    Keywords : Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

    Abstract : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur.

  4. 13. Evaluation of load distribution on ballasted reinforced concrete railway trough bridges

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Alex Eriksson; [2023]
    Keywords : Concrete; numerical analysis; trough bridge; railway bridge; finite element model; discrete element method; Betong; numeriskanalys; trågbro; tågbro; finita elementmetoden; diskreta elementmetoden;

    Abstract : A significant portion of the reinforced concrete railway bridges in Sweden are reaching their designed lifespan and are scheduled to be demolished and replaced in the upcoming years. To limit the econom-icand environmental impact related to the replacement of existing railway infrastructure, a comprehen-siveevaluation of their capacity is required with the aim of extending its lifespan.

  5. 14. The Potential Use of Degradable Starch Microspheres as a Carrier for Nasal Drug Administration

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Rojda Unal; [2023]
    Keywords : Pharmaceutical technology; Nasal administration; Läkemedel; Pulverformiga bärare; Sfärer; Pulverinhalation; Bärarmaterial; Läkemedelseffektivitet; Pulverteknik; Partikelformulering; Nasal deposition; Biology and Life Sciences;

    Abstract : Intranasal drug delivery is a practical and accessible method for treating localized symptoms as well as achieving systemic drug absorption. The approach takes advantage of the permeability, vascularization, and limited enzymatic activity of nasal tissue, leading to enhanced drug absorption. READ MORE

  6. 15. Multi-Scale Topology Optimization of Lattice Structures Using Machine Learning

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Julia Ibstedt; [2023]
    Keywords : Topology optimization; Multi-scale topology optimization; Machine learning; Gaussian process; Homogenization; Inverse homogenization; Anisotropic materials; Symmetry groups; Material property space; Topologioptimering; Flerskalig topologioptimering; Maskininlärning; Gaussian process; Homogenisering; Anisotropa material; Symmetrigrupper; Materialegenskapsrymd;

    Abstract : This thesis explores using multi-scale topology optimization (TO) by utilizing inverse homogenization to automate the adjustment of each unit-cell's geometry and placement in a lattice structure within a pressure vessel (the design domain) to achieve desired structural properties. The aim is to find the optimal material distribution within the design domain as well as desired material properties at each discretized element and use machine learning (ML) to map microstructures with corresponding prescribed effective properties.
