A cubication procedure of the nonlinear differential equation for conservative nonlinear oscillators is analyzed and discussed. This scheme is based on the Chebyshev series expansion of the restoring force and this allows us to approximate the original nonlinear differential equation…

In real-time Multi-Agent Systems, Real-Time Agents merge intelligent deliberative techniques with real-time reactive actions in a distributed environment. CBR has been successfully applied in Multi-Agent Systems as deliberative mechanism for agents. However, in the case of Real-Time Multi-Agent Systems the…

Multi-agent systems are composed of autonomous entities that cooperate forming emergent behaviors. The communication between agents is sometimes unpredictable, and the resulting communication patterns can become crucial in their performance. This paper presents a metrics suite for evaluating the communication…

This special issue of the Journal of Physical Agents is devoted to multi-robot systems. Some might perhaps argue that the term should have been ”multi-agent systems” or ”physical multi-agent systems”, in accordance with the title of the journal. In any…

Two new species of Enclisis Townes, 1970 from Spain are described and illustrated: E. dichroma sp. n. and E. schwarzi sp. n. The new species are distinguished from the closest species E. infernator and E. ornaticeps by head and leg…

En aquest article s’analitzen les relacions existents entre l’ús de la llengua catalana al País Valencià i la inseguretat lingüística. La mostra estudiada, representativa de l’univers estudiat, està formada per 2190 estudiants dels últims anys de l’ensenyament obligatori (entre 14…

Els índexs biomètrics In-recs, In-recj i In-rech complementen la informació obtinguda en la base de dades JCR (Journal Citation Reports) respecte a les publicacions espanyoles, proporcionant l'índex d'impacte d'estes publicacions.

Conocer la historia de la revista Cultura de los cuidados es conocer una parte de la Historia de la Enfermería. Tras 10 años de andadura, es una realidad consolidada gracias, en sus orígenes, a la constancia, empeño, ilusión y
esperanza,…

Antimony-doped tin dioxide electrodes supported on titanium have been used in the electrochemical treatment of aqueous solution
containing phenol. Ti/SnO2–Sb anode has high efficiency in the elimination of phenol, but its use is hindered by its short service
life. The…

Information systems outsourcing is a constantly growing practice in all sorts of organisations. This paper analyses the level of information systems outsourcing at Spanish public universities. It also means to determine if factors such as the size, both of universities…
