aphasia diagnosis is a challenging medical diagnostic task due to the linguistic uncertainty and vagueness, large number of measurements with imprecision, inconsistencies in the definition of aphasic syndromes, natural diversity and subjectivity in test objects as well as in options of experts who diagnose the disease. in this paper we present a new self-organized multi agent system that diagno...

The vertebrate immune system is a complex distributed system capable of learning to tolerate the organisms’ tissues, to assimilate a diverse commensal microflora, and to mount specific responses to invading pathogens. These intricate functions are performed almost flawlessly by a self-organised collective of cells. The robust mechanisms of distributed control in the immune system could potentia...

In this paper we present a self-organizing model for open virtual environments in multi-agent based simulation systems. Open environments are inaccessible, non-deterministic, dynamic and continuous. A virtual environment is partitioned into areas called cells and is supported by an underlying autonomic software system consisting of specialized agents called controllers and coordinators. Control...

Our paper will focus on the use of a multi-agent approach for the introduction of a member in a social network. As for MultiAgents Systems, a global view of a social network is not available and furthermore undesirable. To join a network, each member must build a local network representation according to its needs. Our contribution focuses on the detection of thematic areas to assist the introd...

statement of the problem: hemostatic agents may influence the bond strength of different bonding agents. also, chlorhexidine has shown positive effects on bond strength values and their combination effect has not been reported yet. purpose: the aim of this study was to evaluate the effect of contamination with a hemostatic agent on shear bond strength (sbs) of total- and self-etching adhesive s...

The dynamic behaviour of a mechatronic system can be influenced and optimized in many different ways. One way is to use reactive systems that process measurements of the real system and compute control vectors using a preprogrammed stimulus-response behaviour. The optimization is performed indirectly or by learning procedures which will assess a possible success or failure of the real system. A...

In this paper, we investigate mechanisms via which a group of autonomous agents can produce emergent phenomena in artificial systems. In this framework, emergence deals with the appearance of new properties within a system of interacting agents. More particularly, emergence is here studied from a self-organisation point of view, that is a dynamic appearance of “remarkable” structures of agents....
