  • Isolation Number versus Domination Number of Trees 

    Lemanska, Magdalena; Souto Salorio, María José; Dapena, Adriana; Vázquez Araújo, Francisco José (MDPI, 2021-06)
    [Abstract] If 𝐺 = (Vɢ,Eɢ) is a graph of order n, we call 𝑆 ⊆ Vɢ an isolating set if the graph induced by Vɢ − Nɢ[𝑆] contains no edges. The minimum cardinality of an isolating set of 𝐺 is called the isolation number of ...
  • Green IoT and Edge AI as Key Technological Enablers for a Sustainable Digital Transition towards a Smart Circular Economy: An Industry 5.0 Use Case 

    Fraga-Lamas, Paula; Lopes, Sérgio Ivan; Fernández-Caramés, Tiago M. (MDPI, 2021)
    [Abstract] Internet of Things (IoT) can help to pave the way to the circular economy and to a more sustainable world by enabling the digitalization of many operations and processes, such as water distribution, preventive ...
  • Eye State Identification Based on Discrete Wavelet Transforms 

    Laport López, Francisco; Castro-Castro, Paula-María; Dapena, Adriana; Vázquez Araújo, Francisco Javier; Fresnedo, Óscar (MDPI, 2021)
    [Abstract]: We present a prototype to identify eye states from electroencephalography signals captured from one or two channels. The hardware is based on the integration of low-cost components, while the signal processing ...
  • Wideband User Grouping for Uplink Multiuser mmWave MIMO Systems With Hybrid Combining 

    Pérez-Adán, Darian; Fresnedo, Óscar; González Coma, José Pablo; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2021-03-10)
    [Abstract] Analog-digital hybrid precoding and combining schemes constitute an interesting approach to millimeter-wave (mmWave) multiple-input multiple-output (MIMO) systems due to the low hardware complexity and/or low ...
  • Rank Constrained Precoding for the Downlink of mmWave Massive MIMO Hybrid Systems 

    González Coma, José Pablo; Fresnedo, Óscar; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2021-02-11)
    [Abstract] The hybrid design of precoding schemes for millimeter-wave communications allows exploiting the gains by using large antenna array with an affordable hardware cost and power consumption. In this work, we present ...
