  1. 1. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Svante Rosenlind; [2023]
    Keywords : Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Abstract : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. READ MORE

  3. 2. Turning Night into Day : Does Skyglow affect Bat Activity and Timing of Emergence?

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Torge Gerwin; [2023]
    Keywords : Skyglow; Bats; Light pollution; Bat activity; Bat emergence; Riparian forest; Landscape composition; Multi-scale landscape; Landscape management; Sweden;

    Abstract : Artificial brightness of the night sky caused by the backscatter of artificial light in the atmosphere is a consequence of ongoing urbanization. Skyglow covers 88 % of Europe’s surface and poses significant threats to biodiversity. Extensive research on responses of bats to direct light pollution already revealed significant impacts.

  4. 3. Wind energy and environmental impacts of wind turbine projects

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Chadi Kattach; [2023]
    Keywords : wind; wind turbine; landscape;

    Abstract : My goal in writing this paper was to become more familiar with with wind farm planning and its relationship to the landscape, as a strong and bold intervention in the existing landscape. I examined some of the side effects of onshore wind farms in general, By studying different research on the effects of wind turbines on the surrounding key species such as humans, terrestrial mammals, bats and birds.

  5. 4. Decoding communication of non-human species - Unsupervised machine learning to infer syntactical and temporal patterns in fruit-bats vocalizations.

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Luigi Assom; [2023]
    Keywords : animal decision making; unsupervised machine learning; UMAP; autoencoders; classifiers; bioacoustics; combinatory syntax; animal communication;

    Abstract : Decoding non-human species communication offers a unique chance to explore alternative intelligence forms using machine learning. This master thesis focuses on discreteness and grammar, two of five linguistic areas machine learning can support, and tackles inferring syntax and temporal structures from bioacoustics data annotated with animal behavior.

  6. 5. Constructing a food web from inventory data in a boreal forest-dominated national park in south-eastern Sweden

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Philip Kjellström; [2023]
    Keywords : ecological network; food web; boreal forest food web; national park food web; interspecific competition; swedish forest; construction food web;

    Abstract : A food web was constructed for a boreal-forest dominated national park in south-eastern Sweden, called Tyresta national park and its surrounding nature reserve. Due to increasing threats to mammalian species and their critical role in the food web mammals were used as the outset of the food web, and from there branching out to taxa trophically interacting with mammals directly and indirectly.
