    La actividad cerebral exhibe complejos fenómenos oscilatorios similares a los que se observan en modelos de redes artificiales con osciladores acoplados. Por un lado, estudios sobre la actividad cerebral durante el reposo ...

    Brain states in health and disease: insights from neuroimaging and theoretical neuroscience 

    Escrichs, Anira (Date of defense: 2022-12-12)

    Spontaneous brain activity persists and transitions between brain states, such as from wakefulness to sleep, from development to ageing, or it may transition to pathological states such as coma. Nevertheless, a consensual ...

    Bridging the science of learning and technology enhanced learning: transformative opportunities and ethical challenges 

    Beardsley, Marc Yoshimi (Date of defense: 2021-02-04)

    Reports from the OECD and the World Economic Forum highlight that rapid technological and social change are demanding much more of students. Yet, research indicates that many students are not developing into effective ...

    Building ethernet connectivity services for provider networks 

    Bonada i Cruells, Eduard (Date of defense: 2012-07-16)

    Network providers are motivated to deploy Ethernet in their infrastructures. However, this represents a new application for Ethernet technology that leads to new requirements. In Ethernet networks, the Rapid Spanning Tree ...
