  1. 16. Synthesizing of brain MRE wave data

    Master-uppsats, KTH/Medicinsk avbildning

    Författare :Maryia Yuliuhina; [2023]
    Nyckelord :MR elastography; brain MRE; synthetic data; computational modeling; shear wave elastography; MR-elastografi; hjärn MRE; syntetiska data; beräkningsmodellering; skjuvvåg elastografi;

    Sammanfattning : Magnetic resonance elastography (MRE) is an imaging technique that allows for non-invasive access to the physical properties of body tissues. MRE has great potential, but it is difficult to conduct research due to the time-consuming estimation of stiffness maps, which could be speeded up by using neural network. LÄS MER

  3. 17. The effect of heat and UVC treatments on seed germination and seed-borne fungi of Pinus sylvestris, Pinus contorta and Pseudotsuga menziesii used in Swedish nurseries

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Wiktoria Breza; [2023]
    Nyckelord :seed-borne pathogens; artificial regeneration; conifers; thermotherapy;

    Sammanfattning : Pathogen free seeds are critical to produce healthy plants for forest regeneration. However, recent studies have shown that tree seed carry a high diversity of fungi including known and unknown pathogens. LÄS MER

  4. 18. Development of AI/ML Methods for Advanced Device Localization in Beyond 5G Systems

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Eros Iván Costa Andrés; Jon Aizkorreta Carro; [2023]
    Nyckelord :Artificial Intelligence; localization; IIoT devices; Python; radio signals; 5G; 3GPP; Technology and Engineering;

    Sammanfattning : This master thesis aims to investigate the positioning accuracy improvements of device localization by the implementation of AI/ML functionalities. In this project, we use the fifth-generation(5G) New Radio (NR) system and focus on indoor factories. LÄS MER

  5. 19. Tree Species Impact on Forest Fire Spread Susceptibility in Sweden

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

    Författare :Sara Sharon Jones; [2023]
    Nyckelord :Geography; GIS; Physical Geography; Forest Fire; Forest Fire Susceptibility; Sweden; logistic regression modelling; Earth and Environmental Sciences;

    Sammanfattning : Klimatförändringar förväntas leda till längre brandperioder och ökad brandrisk. I Sverige, där homogen produktionsskog utgör största delen av landskapet, finns ett behov av bättre förståelse för skogens mottaglighet för bränder för att kunna mildra risker. LÄS MER

  7. 20. Analysis and Measurement of Key Performance Indicators for MIMO Antennas

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Ossian Kynman; [2023]
    Nyckelord :MIMO; Diversity Gain; Capacity; Correlation; Fading;

    Sammanfattning : Multiple-in multiple-out (MIMO) is a wireless communication technique where antenna arrays, at the receiver and transmitter, utilize signal multipath propagation to increase data throughput capacity. The unique benefits MIMO provides have over the last 20 years led to the steady increase in usage in both Wi-Fi and mobile networks. LÄS MER
