Current agent platforms do not provide agents the means for reasoning about expected behaviours during interactions. This lack is due to the absence of design primitives to explicitly shape interaction patterns as first-class resources. This work presents 2COMM4JADE, a framework based on JADE and CArtAgO platforms that allows definition of social relationships among parties, represented by soci...

In questo articolo viene presentato MAgentA, un sistema multi-agente sviluppato nel contesto del progetto interuniversitario ANEMONE allo scopo di gestire agende e pianificare riunioni tra gli utenti in modo semiautomatico. Ogni agenda è gestita da un agente che conosce gli impegni personali e le preferenze di un particolare utente, mentre le riunioni vengono organizzate da un apposito agente i...

Cerebral ischemia was produced by moderate compression for 30 min of a specific brain area in the sensorimotor cortex of Sprague-Dawley rats. On day 1, that is 24 h after the transient sensorimotor compression, ischemia-exposed animals displayed a marked focal neurological deficit documented as impaired beam walking performance. This functional disturbance was mainly due to contralateral fore- ...

Organizations and roles are often seen as mental constructs, good to be used during the design phase in Multi Agent Systems, but they have also been considered as first class citizens in MAS, when objective coordination is needed. Roles facilitate the coordination of agents inside an organization, and they give new abilities in the context of organizations, called powers, to the agents which sa...

In the field of blind source separation, joint-diagonalization-based approaches constitute an important framework, leading to useful algorithms such as the popular joint approximate diagonalization of eigenmatrices (JADE) and simultaneous third-order tensor diagonalization (STOTD) algorithms. However, they are often restricted to the case of cumulants of order four. In this paper, we extend the...

Independent Component Analysis (ICA) has found a wide range of applications in signal processing and multimedia, ranging from speech cleaning to face recognition. This paper presents a non-parametric approach to the ICA problem that is robust towards outlier effects. The algorithm, for the first time in the field of ICA, adopts an intuitive and direct approach, focusing on the very definition o...

In this paper, a new combination of Minimum Description Length (MDL) or Eigenvalue Gradient Method (EGM), Joint Approximate Diagonalization of Eigenmatrices (JADE) and Modified Forward-Backward Linear Prediction (MFBLP) algorithms is proposed which determines the number of non-coherent source groups and estimates the Direction Of Arrivals (DOAs) of coherent signals in each group. First, the MDL...
