Temporal Changes in Migratory Seabird Abundance on the Portuguese Coast Reveale...
Fagundes, Isabel; Godinho, Carlos; Ramos, Jaime A; Oliveira, Nuno; Andrade, Joana; Alonso, Hany; Silva, Elisabete; Ferreira, André; Meirinho, AnaLas aguas portuguesas son un corredor migratorio vital para las aves marinas europeas. Los conteos desde la costa pueden monitorizar poblaciones globales y locales de aves marinas, así como estudiar sus tendencias a largo plazo. Hemos empleado el TRIM (Tendencias e Índices para Monitorear Datos) y los Modelos General Aditivos (GAM) en diez años de un conjunto de datos de ciencia ciudadana de conteos de aves mar...
Synchronization and information transmission in networks
Caneco, Acilina; Rocha, LeonelThe amount of information produced by a network may be measured by the mutual information rate. This measure, the Kolmogorov-Sinai entropy and the synchronization interval are expressed in terms of the transversal Lyapunov exponents. Thus, these concepts are related and we proved that the larger the synchronization is, the larger the rate with which information is exchanged between nodes in the network. In fact...
FRONTIERS IN THE STUDY OF CHAOTIC DYNAMICAL SYSTEMS WITH OPEN PROBLEMS
Caneco, Acilina; Rocha, Leonel; Grácio, Clara; Fernandes, SaraWe study the network synchronizability in terms of its local dynamics and in terms of its global dynamics. In previous work we obtained some results about the synchronization interval, when we fix the graph underlying the network, i.e., the network connection topology and vary the dy- namic in the nodes and about the effect of some graph parameters on the synchronization interval, supposing that the local dynam...
Recensão crítica de “New structures and spaces of learning: the systemic impact...
Rocha, LeonelThis recension focuses on the communication presented by George Siemens, on 10th October 2008, at the Web2.0 Meeting in Braga (Portugal), as a part of a line of thought that attempts to interpret the learning and skills developed by individuals who use tools provided by the Social Web. The pressure of technological change, the simplicity of publishing information and knowledge, associated to the increased capac...
