  1. 16. GPS-Free UAV Geo-Localization Using a Reference 3D Database

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Justus Karlsson; [2022]
    Nyckelord :Deep Learning; Machine Learning; ML; AI; UAV; GPS-Free; CNN; 3D CNN; GCNN; 3D Database; geolocalization; geo-localization; georegistration; Hidden Markov Model; HMM; satellite; satellite database; Batch-Hard; triplet loss; PyTorch Geometric;

    Sammanfattning : The goal of this thesis has been global geolocalization using only visual input and a 3D database for reference. In recent years Convolutional Neural Networks (CNNs) have seen huge success in the task of classifying images. The flattened tensors at the final layers of a CNN can be viewed as vectors describing different input image features. LÄS MER

  3. 17. Outdoor environments for physiotherapeutic rehabilitation of work-related stress : lying down in shelter, sitting in serenity, standing in nature and walking in coherence

    Master-uppsats, SLU/Dept. of People and Society

    Författare :Peter Lundkvist; [2022]
    Nyckelord :physiotherapy; exercises; environmental; qualities; stress- related; illness; restoration;

    Sammanfattning : Learning more about rehabilitating work-related stress is important since stress-related illness is creating a lot of human suffering and a significant economic loss in most countries. Physiotherapists are one of the most common professions in work-oriented rehabilitation in Sweden and previous research has shown positive results of using outdoor environments when rehabilitating work-related stress.

  4. 18. Reclaiming Eco Assemblages - Emphasis on ecosystem resilience in human-oriented urban design in Varvsstaden, Malmö, Sweden

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Ghada Ahmed Mahmoud Shaaban; [2022]
    Nyckelord :Post Industrial; Ecosystem Resilience; Green-Blue Infrastructure; Malmö; Öresund; Arts and Architecture;

    Sammanfattning : Many cities are facing the problem of old industrial areas whose soil has been contaminated with toxic substances created by different historical activities within the area. The great unsolved environmental problems, such as: water, soil and air pollution prob- lems, and habitat loss in the Öresund region today, are a result of the industrialization era. LÄS MER

  5. 19. Performance Analysis of Li-fi Communication System

    Master-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Författare :Katrun Nada; [2022]
    Nyckelord :;

    Sammanfattning : Li-fi is a promising technology in today’s communication system. It may bringup the many benefits over other communication technologies. Since light isthe main source to provide data, and this is available everywhere around, itmay compete with other technologies that use radio communication. LÄS MER

  7. 20. Simulation of Radio Propagation Path in Indoor Environment

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Minu Revathikumar; [2022]
    Nyckelord :Indoor 3D propagation model; millimeter waves mmWaves ; 5G; Basic propagation mechanism; Excess loss; Inomhus 3Dspridnings modell; millimeter vågor mmVågor ; 5G; Grundläggande spridnings mekanism; Överskotts förlust;

    Sammanfattning : Several propagation channel models are designed to verify signal behavior in specific environments for future 5G cellular networks. Hence, with the massive development and demand of indoor wireless systems, a suitable design prior to deployment is required for energy and cost-efficient implementations. LÄS MER
