  1. 1. Simulation and Testing of a MU-MIMO Beamforming System

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

    Författare :Nazyar Mehdishishavan; Zonghan Wang; [2023]
    Nyckelord :Multi-User Multiple-Input Multiple-Output MU-MIMO ; Beamforming; Sounding Reference Signal SRS ; Reciprocity-based; Butler matrix; Advanced Antenna System AAS ; Technology and Engineering;

    Sammanfattning : Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology has become increasingly important in the field of wireless communication due to its ability to highly increase the capacity and efficiency of wireless networks [1]. Beamforming, as a technique used in MU-MIMO systems, improves network performance by improving signal quality and reducing interference. LÄS MER

  3. 2. Performance analysis of the communication system of a drone prototype used for maintenance and cleaning

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Abhinav Siddharth Mekam; [2023]
    Nyckelord :Drone; Pixhawk 6C; Raspberry pi; MAVlink protocol; Haarcascade classifier; OpenCV.;

    Sammanfattning : Drones in today’s life are used in many sectors to automate various tasks. Delivering small items, capturing live events, and surveying dangerous areas are a few incredible operations of drones in today’s society. It can perform many tasks in human-restricted areas with less service time and cost. LÄS MER

  4. 3. Velocity Obstacle method adapted for Dynamic Window Approach

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

    Författare :Florian Coissac; [2023]
    Nyckelord :Autonomous navigation; Local planning; Dynamic obstacle avoidance; ROS; Autonom navigering; Lokal planering; Dynamiskt undvikande av hinder; ROS;

    Sammanfattning : This thesis project is part of an internship at Visual Behavior. The company aims at producing computer vision models for robotics, helping the machine to better understand the world through the camera eye. The image holds many features that deep learning models are able to extract: navigable area, depth inference and object detection. LÄS MER

  5. 4. Temporal Dynamics in Urban Design : The Case of Möllevångstorget, Malmö

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

    Författare :Lamiaa Chnayti; [2023]
    Nyckelord :Urban Design; Architecture; Temporality; Rythm Analysis; Public Square; Sustainability; Sustainable Urban Design; Malmö; Möllevångstorget; Möllevången; Arts and Architecture;

    Sammanfattning : Möllevången is a fascinating study of a neighborhood that has undergone significant change and transformation over time. Historically, the area was known for its working-class roots, with crowded narrow streets and traditional Swedish homes; but in recent decades the area has seen waves of gentrification and redevelopment, resulting in a mix of a new and old built environment that has made it one of the most diverse and dynamic places in the city of Malmö.

  7. 5. Black Hole Dynamics in Stellar Clusters

    Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Markus Strickert; [2022]
    Nyckelord :Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

    Sammanfattning : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.
