  1. 1. Enabling Hybrid Real Time and Retrospectively Gated Imaging in a Numerical Phantom

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sara Mineur; [2023]
    Nyckelord :Cardiovascular Magnetic resonance Imaging CMR ; Sector Wise Golden-Angle SWIG ;

    Sammanfattning : Sector-Wise Golden Angle (SWIG) is a novel approach that was developed to address the limitations associated with Golden Angle radial imaging, commonly used for high temporal resolution flow measurements. Golden angle radial imaging is a time-efficient method that effectively reduces motion sensitivity. LÄS MER

  3. 2. De könsambivalenta fotbollsspelarna i sociala medier : En kvalitativ tematisk innehållsanalys och en semiotisk analys

    Kandidat-uppsats, Karlstads universitet

    Författare :Lovisa Hultgren; [2023]
    Nyckelord :representation; gender; social semiotics; football; instagram; representation; genus; socialsemiotik; fotboll; instagram;

    Sammanfattning : Sport coverage is a large part of the traditional media's content, and soccer is the sport that is covered the most. Today, social media offers a new arena where football is monitored, and football clubs now have the opportunity to construct their own coverage. LÄS MER

  4. 3. Performance Evaluation of LoRa networks for Air-to-Ground Communications

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

    Författare :Kiana Khorsandi; Sareh Jalalizad; [2023]
    Nyckelord :IoT; LPWAN; LoRaWan; UAV; LAP; Bit error rate; Line of sight;

    Sammanfattning : The current focus on the Internet of Things (IoT) has led to the emergence of many network scenarios with unlimited use cases, including smart homes, smart cities, smart agriculture, and more. Unmanned aerial vehicles (UAVs), also known as drones, have become increasingly popular due to their versatility and ability to collect and transmit data through various sensors and cameras. LÄS MER

  5. 4. Multifunctional ice and snow repellent coatings for photovoltaic modules

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Gunnar Sandkvist; [2023]
    Nyckelord :sol-gel; superhydrophobic; dip-coating; anti-reflective; silica;

    Sammanfattning : Implementation of solar power by photovoltaic modules in cold climates, such as northern Sweden, implies several challenges. Ice and snow coverage not only leads to reduction in energy production due to shading, but it also puts equipment at risk from additional weight. LÄS MER

  7. 5. Ray Tracing Algorithm for Dielectric Domes

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

    Författare :Maria Pubill; [2023]
    Nyckelord :Array antenna; dielectric dome; Ray-Tracing; reflection; absorption losses; matching layers; Arrayantenn; dielektrisk kupol; strålföljning; reflektion; absorptionsförluster; anpassningsskikt;

    Sammanfattning : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. LÄS MER
