  1. 1. Evaluation and Optimization of LTE-V2X Mode 4 under Aperiodic Messages of Variable Size

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

    Författare :Md Mamunur Rashid; [2023]
    Nyckelord :LTE-V2X; aperiodic; variable size; CAM; Technology and Engineering;

    Sammanfattning : Vehicular networks connect vehicles for improved road safety and efficiency with the assistance of wireless information exchange. Vehicular networks are based on the frequent broadcast of awareness messages referred to as CAM (Cooperative Awareness Messages) or BSM (Basic Safety Message) in the ETSI and SAE standards, respectively.

  3. 2. Pasture related characteristics and management strategies associated with udder health in farms with an automatic milking system : impact on somatic cell count and milking frequency

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

    Författare :Emma Laufors; [2022]
    Nyckelord :somatic cell count; milking interval; automatic milking system; udder health; heat stress; pasture strategies; preventative measures;

    Sammanfattning : Udder health plays a central role in the dairy industry and poor udder health can entail both negative economic and animal welfare consequences as well as increased antimicrobial use. The somatic cell count (SCC, a commonly used measurement of udder health) has been observed to increase during the summer season both in Sweden and in other countries. LÄS MER

  4. 3. Adaptive Beam Management in 5G-NR: A Machine Learning Perspective

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

    Författare :Boqiang Wang; [2021]
    Nyckelord :Machine Learning; Neural Network; Beam Management; Beam Tracking; mmWaves; 5G NR; Beamforming; Technology and Engineering;

    Sammanfattning : In this rapid era of technology, speed of communication has become an important factor. To overcome this challenge, 5G/NR technology is being explored. One of the ways of doing this is by using the so called millimeter wave spectrum. LÄS MER

  5. 4. Machine Learning Technique for Beam Management in 5G NR RAN at mmWave Frequencies

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

    Författare :Joel Bill; Gustav Fahlén; [2020]
    Nyckelord :Machine Learning; Reinforcement Learning; Beam Management; Beam Tracking; mmWaves; Technology and Engineering;

    Sammanfattning : Ericsson has an interest in investigating if the fast-growing concept known as machine learning can be applied to beam management, in a 5G NR environment using mmWave frequencies. Because of the high path-loss at mmWave frequencies and high throughput demands of 5G NR systems it is crucial to the UE to always stay connected to the most suitable beam, to provide highest possible throughput.

  7. 5. Hållbara telefoner inom verksamheter - En studie om användandet av mobiltelefoner hos företag och hur valet av mobil kan ske med hänsyn till hållbarhet

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Victoria Pehrsson; [2020]
    Nyckelord :Hållbarhet; smartphones; IT; mobiltelefon; återanvändning; återvinning; cirkulär ekonomi; företag; Earth and Environmental Sciences;

    Sammanfattning : The cell phone industry is one of the most linear sectors, which means high resource consumption in the production of telephones and difficulties in repair. In addition, only 10-12% take-back of used units takes place, the rest are often forgotten in drawers or handled incorrectly. LÄS MER
