  1. 1. Estimating Diffusion Tensor Distributions With Neural Networks

    Master-uppsats, Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Rimaz Nismi; [2024]
    Nyckelord :Diffusion; Magnetic Resonance Imaging; MRI; Neural Networks; Optimal transport; Earth mover s distance; Sinkhorn distance;

    Sammanfattning : Magnetic Resonance Imaging (MRI) is an essential healthcare technology, with diffusion MRI being a specialized technique. Diffusion MRI exploits the inherent diffusion of water molecules within the human body to produce a high-resolution tissue image. An MRI image contains information about a 3D volume in space, composed of 3D units called voxels. LÄS MER

  3. 2. The accuracy of road distances in the Antonine itinerary

    Master-uppsats, Lunds universitet/Antikens kultur och samhällsliv

    Författare :Tomas Öberg; [2023]
    Nyckelord :History and Archaeology;

    Sammanfattning : The Antonine itinerary was compiled in the early fourth century CE and is a key source to our know¬¬ledge about ancient geography and the Roman road system. However, the major research work dates more than 100 years back in time and few studies have been focussed on its overall reliability. LÄS MER

  4. 3. Scalable Nonparametric L1 Density Estimation via Sparse Subtree Partitioning

    Master-uppsats, Uppsala universitet/Statistik, AI och data science

    Författare :Axel Sandstedt; [2023]
    Nyckelord :density estimation; scalable density estimation; nonparametric density estimation; scalable nonparametric density estimation; L1; L_1; anomaly detection; regression analysis;

    Sammanfattning : We consider the construction of multivariate histogram estimators for any density f seeking to minimize its L1 distance to the true underlying density using arbitrarily large sample sizes. Theory for such estimators exist and the early stages of distributed implementations are available. LÄS MER

  5. 4. Bluetooth Based Bird Detection System

    Kandidat-uppsats, Blekinge Tekniska Högskola

    Författare :Muppireddy Sai Charan Reddy; Veera Venkata Satyanarayana Murthy Namuduri; [2023]
    Nyckelord :Bluetooth; Avifauna; Signal strength; Distance estimation; Bird Detection;

    Sammanfattning : Context: Windmills became one of main sources of energy. Sincethey are placed in open areas, there are many chances that birds mayenter the wind farms and get killed or damaged. Some wind farms usepulse radar systems for saving the birds from windmills. In this pulseradar technology, the turbines are turned off automatically when a birdis detected. LÄS MER

  7. 5. Estimating Future Forest Fire Risk in Gävleborg County Sweden in 2041-2070 Following RCP 8.5

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Vendela Cyrén; [2023]
    Nyckelord :Future forest fire risk; RCP 8.5; Gävleborg county; Climate change; Forest fire; Earth and Environmental Sciences;

    Sammanfattning : Forest fires can act as an ecosystem service by providing habitat renewal, controlling pests, and reducing the risk of extreme fires, but can at the same time disturb an ecosystem negatively. Furthermore, forest fires release carbon dioxide into the atmosphere, damage property, and lead to health issues. LÄS MER
