This article presents our prototype MASET (Multi Agents System for E-Tutoring Learners engaged in online collaborative work). MASET that we propose is a system which basically aims to help tutors in monitoring the collaborative work of students and their various interactions. The evaluation of such interactions by the tutor is based on the results provided by the automatic analysis of the inter...

In this contribution we generalize some links between contrasts functions and considering of a reference signal in the field of source separation. This yields a new contrasts that allows us to show that a function proposed in [4] is also a contrast, and frees us from the constraints on the introduced reference signal [1]. Associated optimization criteria is shown to have a close relation to a j...

Multi-agent technology, a modern computer science tool, is widely used in developing intelligent systems. Agents in multi-agent system are autonomous and capable of doing tasks independently, however they share information with each other to achieve their respective goals. Information may be a result of task or a request to other agent to perform some task. To develop an integrated system, data...

The goal of blind beamforming is to recover source signals only from the output of array without any a priori information about the array manifold. For the separation of independent sources, Cardoso and Souloumiac proposed an effectively blind beamforming method (JADE) using fourth-order cumulant. However, the high computation complexity of this method limits its applicability in many practical...

Like in any distributed systems, communication in Multi-Agent System (MAS) plays an important role as it helps agents sharing knowledge and facilitating cooperation. Communication in MAS may present at various forms; it can be exchanging of comprehensible messages, or requesting to perform an action, or negotiating cooperation. Agent communication has common properties like in any other distrib...

This paper proposes a new multimode wireless receiving system based on Blind Source Separation (BSS) for Orthogonal Frequency Division Multiplexing (OFDM) signal (based on Wireless Local Area Network (WLAN)) and the Wideband Code Division Multiple Access (WCDMA) signal (based on 3G cellular system). The proposed system applied the Independent Component Analysis (ICA) algorithms (adopting Fast-I...

A new method is presented to determine the gluon density in the proton from jet production in deep inelastic scattering By using the technique of Mellin transforms not only for the solution of the scale evolution equation of the parton densities but also for the evaluation of scattering cross sections the gluon density can be extracted in next to leading order NLO QCD This method is however mor...

Ambient Intelligence (AmI) can be taken as one of the principal test beds for the integration of Systems, Humans and Cybernetics. Multi-agent based Ambient Intelligence solutions have proliferated in the last few years in order to cope with the intrinsically distributed and complex interaction based nature of the problem. Different multi-agent platforms have been used in this regard, being JADE...

The Aircraft Surveillance Applications System (ASAS), what used to be called Airborne Separation Assistance System, is seen as a promising option in future Air Traffic Management (ATM) for increasing capacity and operational effectiveness, and improving safety while reducing fuel consumption. One of the interesting ASAS applications is to achieve desired time intervals between arrival aircraft ...

This paper presents a novel JADE add-on that enables the implementation of location-aware agents by interfacing an underlying ranging technology which provides accurate distance measures both indoor and outdoor. First, the paper motivates the work and it presents the features and the architecture of the add-on. Then, the paper provides a detailed description of the implemented localization algo...
