  1. 1. Multidimensional Classification of Radar Signals : A comparison between unidimensional and multidimensional classification models for pulsed radar signals

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Max Ek Törmä; [2023]
    Nyckelord :pulsed radar classification; Bayesian Gaussian mixture models; Dirichlet process mixture models; multidimensional radar classification; pulsed radar signals; radar signal classification;

    Sammanfattning : Radar is a technique used by many different types of remote sensing systems to keep track of their surroundings. The transmitted radar signals may carry information that could be used to infer the type of transmitter. Multiple papers have investigated the classification of pulse repetition intervals produced by radar systems. LÄS MER

  2. 2. Impact of Sea Surface Temperature and Salinity on Phytoplankton blooms phenology in the North Sea

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

    Författare :Krystyna Muszel; [2023]
    Nyckelord :Geography; GIS; North Sea; phytoplankton; bloom; phenology; remote sensing; TIMESAT software; Earth and Environmental Sciences;

    Sammanfattning : Various environmental forcings can affect phytoplankton blooms, resulting in changes in bloom timing and abundance, which can have many far-reaching consequences. Understanding bloom phenology is crucial to predict and counter any potential harmful changes. LÄS MER

  3. 3. In-Situ Gold Resource Estimation Using Satellite Remote Sensing and Machine Learning in Defunct Tailing Storage Facilities (South Africa)

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Shenelle Agard; [2023]
    Nyckelord :tailings storage facility; critical raw materials; machine learning; mine valorisation;

    Sammanfattning : The mining industry generates billions of tonnes of waste annually, which is often stored in tailings storage facilities (TSF). This waste is generated from the extraction of ore from surface or underground mines, as well as from metallurgical processing and low-grade stockpiles. LÄS MER

  4. 4. Urban tree canopy mapping -an open source deep learning approach

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

    Författare :Tobias Rydlinge; [2023]
    Nyckelord :Geography; GIS; AI; deep learning; urban trees; remote sensing; Earth and Environmental Sciences;

    Sammanfattning : Urban trees have an important role to provide ecosystem services and to make our cities greener and more sustainable. The changing climate and densification of cities make it even more valuable to preserve and investigate in urban trees. LÄS MER

  5. 5. Petrography of impactites from the Dellen impact structure, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Robert Mroczek; [2023]
    Nyckelord :Dellen; Impact; structure; magnetite; apatite; shock waves; shock-metamorphic; features; Impactite; petrography; scanning electron microscope; SEM; geology; Earth and Environmental Sciences;

    Sammanfattning : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.
