  1. 1. 3D Modeling of Factory Scenarios for 5G Evaluations

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Haodong Zhao; [2023]
    Nyckelord :;

    Sammanfattning : 5G is a key enabler for a variety of use cases in smart manufacturing which requires communications with high reliability and low latency. In a dynamic industrial environment, objects such as machines, production lines, storage shelves, robotic arms, and automatically guided vehicles may cause fading and have a large impact on radio propagation.

    Sammanfattning : Game engines are well known for their use in the gaming industry but are starting to have an impact in other areas as well. Architecture, automotive, and the defence industry are today using these engines to visualise and, to some extent, test their products. LÄS MER

  4. 3. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

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

    Författare :Zhenyu Li; [2023]
    Nyckelord :mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

    Sammanfattning : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. LÄS MER

  5. 4. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

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

    Författare :Lukas Jonasson; [2023]
    Nyckelord :Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

    Sammanfattning : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. LÄS MER

  7. 5. Vem sköt på Bomarsund i augusti 1854? : pXRF-analys av blykulor och dess anslag kopplade till rörelser i landskapet under slaget om Bomarsund 1854

    Master-uppsats, Stockholms universitet/Institutionen för arkeologi och antikens kultur

    Författare :Benjamin Rosten; [2023]
    Nyckelord :;

    Sammanfattning : The Battle of Bomarsund was fought by three nations, all of which left behind lead residues at the site. These residues consist of both lead bullets from rifles, as well as impact marks from bullets fired at the fort. LÄS MER
