  1. 16. Carabidocoenoses and Fragments of Forests : exploring the Carabid Landscape

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Simon Heinrich Arns; [2023]
    Nyckelord :biodiversity; Carabidae; carabid diversity; entomology; Fragmentation; Fragstats; habitat fragmentation; habitat Heterogeneity; landscape; landscape ecology; landscape Heterogeneity; pitfall trap; quantifying fragmentation;

    Sammanfattning : Epigeic ground beetles (Coleoptera: Carabidae) were sampled between 2021-06-28 and 2021-07-09 using pitfall traps in the Swedish counties Värmland and Gävleborg. The structural properties of the landscapes surrounding these points were estimated from the Swedish Environmental Protection Agency’s national land cover databases and the Swedish Forest Agency’s data for all formally protected and high conservation value forests using patch-based configurational metrics.

  3. 17. Detection of local motion artifacts and image background in laser speckle contrast imaging

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Johannes Nyhlén; Märta Sund; [2023]
    Nyckelord :laser speckle contrast imaging; lsci; multi exposure laser speckle contrast imaging; melsci; machine learning; deep learning; statistical analysis; detection; local motion artifacts; 1D; 2D; 3D;

    Sammanfattning : Laser speckle contrast imaging (LSCI) and its extension, multi-exposure laser speckle contrast imaging (MELSCI) are non-invasive techniques to monitor peripheral blood perfusion. One of the main drawbacks of LSCI and MELSCI in clinical use is that the techniques are sensitive to tissue movement. LÄS MER

  4. 18. Musikgenerering med Generativa motståndsnätverk

    Master-uppsats, Jönköping University/JTH, Avdelningen för datavetenskap

    Författare :Yupeng Li; Jonatan Linberg; [2023]
    Nyckelord :Artificial Intelligence; AI; Music; Generative Adversarial Networks; Artificiell Intelligens; AI; Musik;

    Sammanfattning : At present, state-of-the-art deep learning music generation systems require a lot time and hardware resources to develop. This means that they are almost exclusively available to large companies. In order to reduce these requirements, more efficient techniques and methods need to be utilised. LÄS MER

  5. 19. Efficient Utilization of Video Embeddings from Video-Language Models

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Felix Lindgren; [2023]
    Nyckelord :VLM; CLIP; transformers; machine learning; video retrieval; activitynet; efficient training; aggregation;

    Sammanfattning : In the digital age where video content is abundant, this thesis investigates the efficient adaptation of an existing video-language model (VLM) to new data. The research leverages CLIP, a robust language-vision model, for various video-related tasks including video retrieval. LÄS MER

  7. 20. Optimal foraging in an Arctic herbivore : How does the foraging behaviour of Svalbard reindeer (Rangifer tarandus platyrhynchus) respond to seasonal changes from summer through autumn of the Arctic tundra?

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Emma Limosa Djurberg; [2023]
    Nyckelord :foraging behaviour; phenology; ungulate; Arctic; Rangifer tarandus platyrhynchus;

    Sammanfattning : Foraging decisions of large herbivores can be affected by many factors and have great effect on both above- and below-ground ecosystems. Here, I determine to which degree temporal (seasonality), or spatial (habitat) factors influence the foraging behaviour of Svalbard reindeer (Rangifer tarandus platyrhynchus) and asses if small-scale foraging behaviour correlates with an animals’ patch residence time.
