    Almalkawi, Islam; Al-Abed, Loiy; Al-Karaki, Jamal N.; Guerrero Zapata, Manel (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Conference lecture
    Open Access
    IoT systems provide excellent solutions to many applications in both civilian and military aspects. This is even facilitated by the advent of many types of cameras with the diminishing cost of communication devices. We ...
  • Property rights in servitisation: a practical assessment with reused computers 

    Roura Salietti, Mireya; Navarro Moldes, Leandro; Meseguer Pallarès, Roc (Springer, 2022)
    Conference report
    Open Access
    The circular economy of computers is about producing fewer, more durable and reusable products while investing in expanding their life span through a functional service economy. Reuse is often mentioned as a sustainable ...
  • Integrating a neural network library in embedded federated learning 

    Aatab, Soufiane; Freitag, Fèlix (Institute of Electrical and Electronics Engineers (IEEE), 2023)
    Conference report
