    Sammanfattning : Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissions by changing the traffic signal programs.

  3. 2. A Study on Data-driven Methods for Selection and Evaluation of Beam Subsets in 5G NR

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

    Författare :Nic Ekman; Ilias Theodoros Skordas; [2022]
    Nyckelord :5G; NR; telecom; telecommunications; ML; machine learning; algorithms; beam; widebeam; propagation; beamforming; subset; RAN; radio; radio environment; ericsson; Technology and Engineering;

    Sammanfattning : 5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years.

    Sammanfattning : På arbetsförmedlarna ställs det höga krav på att leverera bra resultat, dels utifrån föreställningen hos allmänheten om att Arbetsförmedlingen tillhandahåller jobb, dels på myndighetens krav på att få ut de sökande ur systemet snabbt och effektivt. Handläggarnas yrkesroll innebär en viss komplexitet, något som denna studie har även bestyrkt. LÄS MER
