• CoLLIDE: cloud latency-based identification

  Daza, Vanesa; Di Pietro, Roberto; Lombardi, Flavio; Signorini, Matteo (Elsevier, 2017)

  As services steadily migrate to the Cloud, the availability of an overarching identity framework has become a stringent need. Moreover, such an identity framework is now critical in the Internet of Things. To address this ...
• Learning to learn: university student perceptions of a science of learning intervention

  Beardsley, Marc; Martínez Moreno, Judit; Hernández Leo, Davinia (2020)

• Comparing pre-service and in-service teacher perceptions of the science of learning

  Beardsley, Marc; Martínez Moreno, Judit; Hernández Leo, Davinia (2020)

  This paper presents the results of a survey on teacher formation and beliefs related to the science of learning (e.g. the science of how people learn) completed by in-service and pre-service teachers. The study results ...
• A survey on machine and statistical learning for longitudinal analysis of neuroimaging data in alzheimer's disease

  Martí Juan, Gerard; Sanromà, Gerard; Piella Fenoy, Gemma (Elsevier, 2020)

• Modeling the formation of social conventions from embodied real-time interactions

  Freire, Ismael T.; Moulin-Frier, Clement; Sánchez Fibla, Martí; Arsiwalla, Xerxes D.; Verschure, Paul F. M. J. (Public Library of Science (PLoS), 2020)
