    Following the trend of other safety-critical industries like automotive and avionics, the space domain is witnessing an increase in the on-board computing performance demands. This raise in performance needs comes from ...
  • Embeddability of Kimura 3ST Markov matrices 

    Roca Lacostena, Jordi; Fernández Sánchez, Jesús (2018-05-14)
    Article
    Open Access
    In this note, we characterize the embeddability of generic Kimura 3ST Markov matrices in terms of their eigenvalues. As a consequence, we are able to compute the volume of such matrices relative to the volume of all Markov ...
  • Energy efficient transmit-receive hybrid spatial modulation for large-scale MIMO systems 

    Raafat Hosny Mohamed Fahm, Ahmed; Sefunç, Merve; Agustín de Dios, Adrián; Vidal Manzano, José; Jorswieck, Eduard Axel; Corre, Yoann (2020-03-01)
    Article
    Open Access
    We consider a point to point large-scale multipleinput multiple-output (MIMO) system operating in the millimeter wave (mmWave) band and an outdoor scenario. Novel transmit and receive spatial modulation (SM) schemes are ...
  • Multi-year prediction of European summer drought conditions for the agricultural sector 

    Solaraju Murali, Balakrishnan; Caron, Louis-Philippe; Gonzalez-Reviriego, Nube; Doblas-Reyes, Francisco J (2019-11-27)
    Article
    Open Access
    Decadal climate prediction, where climate models are initialized with the contemporaneous state of the Earth system and run for a decade into the future, represents a new source of near-term climate information to better ...
  • Structural size effect: experimental, theoretical and accurate computational assessment 

    Barbat Vlad, Gabriel; Cervera Ruiz, Miguel; Chiumenti, Michèle; Espinoza Durán, Eduardo (Elsevier, 2020-06)
    Article
    Restricted access - publisher's policy
    In this paper, experimental evidence, theoretical predictions and the finite element modelling of the structural size effect in cracking problems of quasi-brittle materials are discussed and assessed against each other. ...
