  1. 1. Påverkande faktorer vid upphandling av digitala Informationssystem inom offentligsektor

    Master-uppsats, Mittuniversitetet/Institutionen för kommunikation, kvalitetsteknik och informationssystem (2023-)

    Författare :Mats Falkeman; [2023]
    Nyckelord :public procurement; digital collaboration platform; remote work; sociomateriality; IT artifact.; offentlig upphandling; digital samarbetsplattform; distansarbete; sociomaterialitet; IT‐artefakt;

    Sammanfattning : Before the pandemic, many public sectors were heavily dependent on American cloud services. When the pandemic broke out, remote work became a necessity, making existing communication systems like Skype, email, and file sharing crucial to support this transition. LÄS MER

    Sammanfattning : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. LÄS MER

  4. 3. Over-the-Air Federated Learning with Compressed Sensing

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Adrian Edin; [2023]
    Nyckelord :machine learning; ML; Federated Learning; FL; Over-the-air; Over-the-air computation; OtA; OtA computation; AirComp; Compressed sensing; CS; Iterative Hard thresholding; IHT;

    Sammanfattning : The rapid progress with machine learning (ML) technology has solved previously unsolved problems, but training these ML models requires ever larger datasets and increasing amounts of computational resources. One potential solution is to enable parallelization of the computations and allow local processing of training data in distributed nodes, such as Federated Learning (FL). LÄS MER

    Sammanfattning : As the demand for better and faster applications increase every year, so does the demand for new communication systems between computers. Today, a common method for computers and software systems to exchange information is the use of REST APIs, but there are cases where more efficient solutions are needed. In such cases, RPC can provide a solution. LÄS MER
