  abstract = {In order to simulate biological processes, we use multi-agents system. However, modelling cell behavior in systems biology is complex and may be based on intracellular biochemical pathway. So, we have developed in this study a Fuzzy Influence Graph to model MAPK pathway. A Fuzzy Influence Graph is also called Fuzzy Cognitive Map. This model can be integrated in agents representing cells. Results indicate that despite individual variations, the average behavior of MAPK pathway in a cells group is close to results obtained by ordinary differential equations. So, we have also modelled multiple myeloma cells signalling by using this approach.}

in a natural setting. Twelve French football players were observed during a specially designed study
favourising counter-attacks. Players then watched a videotaped recording of their performance and
provided the researcher with a verbal description of their cognitive activity during the situation. A
content analysis conducted in context identified recurrent meanings produced by the experts. The data
revealed that the players employed 16 schemata in the natural context of counter-attack. The main results
highlight a number of aspects concerning experts' decision-making processes: experts' recognition of
typical situations, the flexibility of schemata in decision-making, the evolution of the activity on the basis
of contextual cues. The results provide a deeper understanding of complex football decision-making
activity, and have been used for the development of the virtual environment CoPeFoot (Collective

Tactile maps are powerful tools to help them to encode spatial information. However only didgital charts can be updated during voyage and they very often only rely on the visual modality. Virtual reality can present information using auditory and haptic interfaces. Previous work showed that virtual navigation facilitates acquiring spatial knowledge. This study aims at measuring if a blind sailor can learn a maritime environment with a virtual map as well a with a tactile map. The results tend to confirm this, and suggest pursuing investigations with non visual virtual navigation}

  abstract = {In an accompanying paper, we addressed the issue of synchronization under
		the framework of tissular coupling and in the case of a finite population. This
		issue is one of the main dynamical emergent property of complex systems.
		Indeed, this phenomenon actually occurs in natural systems at many scales
		(from cell to whole ecological systems). Many
		examples can be found in various fields of experimentation and theoretical
		research. It is in particular a key concept in the field of non-
		linear systems' dynamics, especially through the notion of chaotic systems'
		synchronization. This wide source of examples explain why this field of
		research is highly interdisciplinary, from pure theory to concrete applications
		and experimentations. The classical concept of synchronization is related to
		the locking of the basic frequencies and instantaneous phases of regular oscillations. 
		Those issues are usually addressed by studying specific coupled
		systems, using classical tools of the field. Convinced that
		synchronization phenomenon is completely natural in a large variety of coupled dynamical systems, 
		we proposed in a preceding paper a new approach to
		the subject: we built a general model of coupled systems, called « tissular coupling ». 
		Within natural assumptions on interactions of those coupled systems,
		we proved that, for a wide class of autonomous differential systems, as soon
		as a finite population exhibits oscillating behaviors, their frequencies are mutually 
		locked to a single value. This paper presents a new piece of answer

		connected population. Even if the general questions addressed in this paper
		are similar to those addressed in the later one, this study is done with completely different 
		techniques than in the finite situation and the results achieved
		require assumptions that are specific to the continuous situation.

		This paper
		stresses the fact that synchronization is a very natural phenomenon that can
		be find in many kind of coupled dynamical systems.
		In the first section, we recall some parts of the framework already introduced and some 
		mathematical tools specific to our problem. Then we address
		a sub problem which deals with diffuse coupling, concluding with a general
		result on synchronization. Finally, we go back to the general case of a uniformly linear

  abstract = {Synchronization is an extremely important and interesting emergent property
		of complex systems. The first example found in literature goes back to the
		17th century with Christiaan Huygens works. This kind of emergent
		behavior can be found in artificial systems as well as in natural ones and at
		many scales (from cell to whole ecological systems). Biology abounds of peri-
		odic and synchronized phenomena and the works of Ilya Prigogine showed that
		such behaviors arise within specific conditions: a dissipative structure gener-
		ally associated to a non-linear dynamic. Biological systems are open, they
		evolve far from thermodynamic equilibrium and are subject to numerous reg-
		ulating processes, leading to highly non-linear dynamics. Therefore periodic
		behaviors appear (with or without synchronization) at any scale. More
		generally, life itself is governed by circadian rhythms. Those phenomena
		are as much attractive as they are often spectacular: from cicada populations
		that appear spontaneously every ten or thirteen years or networks of heart
		cells that beat together to huge swarms in which fireflies, gathered in a
		same tree, flash simultaneously. Furthermore, beyond biology one can find a
		wide source of examples in completely different fields of science (e.g. in behav-
		ioral psychology with the example of synchronizing applause). For much
		more artificial and/or theoretical examples, one can consider the whole field
		of research that studies the coupling of smooth dynamical systems. Nowa-
		days, it is one of the most important subject related to non-linear systems'
		dynamics, especially through the notion of chaotic systems' synchronization. 
		This wide source of examples leads the field of research to be highly
		interdisciplinary, from pure theory to concrete applications and experimen-
		tations. The classical concept of synchronization is related to the locking of
		the basic frequencies and instantaneous phases of regular oscillations. Those
		questions are usually addressed by studying specific kinds of coupled discrete
		or differential systems, using classical tools of the field.
		Convinced that synchronization phenomenon is completely natural in a large
		variety of coupled dynamical systems, we propose a new approach of the subject: 
		firstly, we ask the question of synchronization differently than the usual
		way. Rather than trying to prove that synchronization actually takes place,
		we search conditions under which frequencies are locked as soon as the whole
		system oscillate. Secondly we enlarge the scope of handled models, by building 
		a general framework for coupled systems called « tissular coupling ». This
		framework is inspired by biological observations at cell's scale, but relevant at
		any scale of modeling. Under some general assumptions on the kind of interactions 
		that constitute the coupling of the systems, we prove that for a wide
		class of tissular coupling systems, frequencies are mutually locked to a single
		value as soon as the whole population is oscillating.

		    This paper exhibits our model of tissular coupling and the frequency locking 
		in the case of a finite number of coupled systems. In the first section we
		present some mathematical tools and the background we have used in order
		to study synchronization issue (the results exposed at the end of this paper
		is only a part of what we have fulfilled, and surely a really small part of what
		can be done using tissular coupling, this is why we state this framework in
		its general form). Then, we describe dynamical objects on which we focus,
		namely the tissular coupling and periodical motions of a population. In the
		second section we expose a useful way to reduce the problem to a structural
		one, with no more reference to the dynamics of the coupled systems. In the
		final section we exhibit some natural conditions under which we are able to
		prove the main result of this paper, a case of synchronization, in terms of
		frequencies locking. In a second paper [3] we expose the case of an infinite
		compact and connected population, which is processed with different mathematical tools.}

		   According to current theories, people without vision are able to construct cognitive maps of their 
		   environment but the lack of sight tends to lead them to build egocentric and sequential mental pictures 
		   of space. Nevertheless, exocentric and unified representations are more efficient (Piaget et al, 1948). 
		   Can blind people be helped to construct more effective spatial pictures? Some previous works have shown 
		   that strategies are the most important factors in spatial performance in large-scale space 
		   (Tellevik, 1992) (Hill et al, 1993) (Thinus-Blanc et al, 1997). In order to encode space in an efficient way,

		   a compass establishes a frame of external cues. In this respect, we support the assumption that training 
		   based on systematic exocentric reference helps blind subjects to build unified space. At the same time, 
		   this training has led the blind sailor to change his haptic strategies in order to explore tactile maps 
		   and perform better. This seems to modify his processing of space representation. Eventually, we would 
		   like to study the transfer between map representation and environment mobility. Our final point is about

 		More precisely, the aim of our work is to determine how computer scientists can take benefit from immune phenomenon
		to auto-regulate agent populations.
		This regulation can be made while integrating cell and molecule behaviors into agent's behaviors.
		Let us quote for example the mitosis, apoptosis or differenciation that are essential mechanisms
		during an immune response. The work to do or the problem to be solved are seen as foreign substances,
		that is antigenic bodies.
		The agents represent immuno-qualified cells having for goal the antigen inhibition.
		This process must be efficient, that means it must finish the work
		and just the work to do. Each agent inherit from one or several cell behaviors.
		Those behaviors are extracted from immune cells which have well defined roles.
		The first consists in detecting the antigen (the work to do), the second in giving alarm on
		a large scale, the third in increasing the capacity and the precision of the response and the
		fourth in eliminating the antigen.
		Our agents use these roles to mime an immune response.
		Hereafter we explain, in three criteria, the reasons of the immune response choice for MAS.
		1)The immune system is compound with autonomous entities, able to cooperate, having behaviors,
		receptors and means of action. Therefore, a cell is very close to the agent concept.
		2)The immune system is able to divide « self » and « non-self ». Like this, it can detect the work
		to do among 1020 different patterns. Thus, this system is flexible and adaptative, what gets an
		unquestionable advantage in environments with strong variability (like for aerial images).
		This number of possible shapes is very important, but it can be reduce for the need of simulation
		3)The human immune system is quasi-optimal in the power of the answer to eliminate the antigen,
		which would allow us a quasi-optimal use of the computer resources during multi-agents processes.
		The regulation of multi-agents system thanks to immunological principles is few used today.
		We will begin with the study of the immune concepts we use as metaphors for the regulation of the agent populations.
		Then, we show two examples illustrating the implementation of the immune concepts.
		They are dedicated to the image processing coded in levels of gray.
		Finally, we conclude on the interests of this immune approach for the design of MAS.}

		 cell population on an other cell population. This approach is particularly well
		 adapted to the in-vivo phenomena simulation. In this case, the number of cells taken
		 into account is very important ($n > 10^{12}).
		 Another model consists in the local description of a cell's behavior, and in the
		 description of its receptors. The simulation manages to determine interactions between
		 the cells. Therefore, global phenomena are seen as the emergence of all the individual
		 interactions.
		This last approach started in the early nineties with the work of Forrest on the
		receptor description and Seiden \& Celada on the humoral response and thymus activity.
		The main advantages of such an approach are the modularity and its incremental aspect.
		The modularity allows a quite simple addition or removal of agents. The incremental
		aspect is the ability to easily improve the cell-agent model.
		That is the reason why the studies have been quickly extended by Smith on vaccine
		efficacy, by Seaden's team on rheumatoid factors and Ballet on humoral response against
		HIV virus. By now, these models have no geometrical constraints.
		Therefore, we have decided to develop a multiagent system doted whith geometrical
		constraints. Thus, we are able to simulate in-vitro experimentations into which the
		geometrical aspect is important. Thanks to the simple geometrical restraints, this
		study demonstrates that it is possible to simulate several in-vitro experimentations.
		We present in this paper our simulator and three in-machina experimentations. each of
		them are compared whith the real in-vitro tests.}

  abstract = {The immune system mechanisms are very complex
		and the number of parameters is extremely important.
		Moreover, the interactions beetween the different cells
		during an immune response induce chaotics and non
		linear phenomena. Our approach consists in using the
		cooperative models, established by the immunologists,
		to build a multi-agent model. Like this, we avoid the
		problem of non-determinism by only encoding the basic
		behaviors of the agents, and the global chaotic phenomena 
		are induced by the interactions between the agents.
		The advantages, face to the mathematical models, are
		that each agent could be viewed, modified, removed
		from the model or added to the model very easily. That
		is not the case in mathematics where a modification of
		an assumption generaly involves the rewriting of the
		model. This approach is possible because the behaviors 
		of several immune system cells are known in their
		principal lines and some qualitative models of immune
		cell cooperations have been developped by immunologists. 
		These models have already demonstrated their
		validity localy in time and in space, i.e they have not
		a global approach. With the multi-agent system, we
		can, thanks to the simulation, analyse the global consequences 
		from the local behaviors and observe a qual-
		itative striking resemblance to statistical results coming 
		from a real experimentation. We have chosen to
		simulate a human secondary humoral response with a
		multi-agent system to study the cinetic of the antibody
		proliferation with severals type of antigenic substances.}

 		   The reactivity being very important, the agents' behavior is very simple (perception-action): 
		   they have the capacity, nevertheless, to adapt locally to what they consider their environment, that is to say the image. 
		   An agent can move and has its own position in its environment. The basic behavior for an agent consists of following the 
		   highest brightness gradient and inscribing its path, if estimating to be on an edge, in all the agents' shared memory. 
		   Its path thus corresponds to edges which are found in the image. Please note that, in order to be noise resistant, 
		   the path is actually stored in the shared memory only if it is long enough. The notion of shared memory is very important 
		   because it allows the interaction among agents and the coordination of their actions. The agents actually use already 
		   found edges for finding new ones or complete those already detected. We have tested this system on different gray scale 
		   images scenes, but as well on synthetic scenes allowing analysis of thus obtained results. The results are promising and 
		   especially fast. Our multiagent system has been tested on a single-processor computer, and it has been noted that the 
		   number of agents in a simulation neither affects the quality of the result nor CPU time necessary for segmentation of a 
		   given scene. We think that this approach is original in its use of agents and may be used to implement parallel image 
		   processing by assigning, for instance, an agent to each processor.}

  abstract = {We present a method for detecting concentric strias which can be found in different natural 'objects'. 
 		   One of the major problems encountered during an automatic image processing is the lack of continuity perception in strias. 
		   We propose an approach to this continuity perception based on a multiagent system made up of reactive agents. 
		   These agents can move around on their environment which consists of an image made up of light and dark rings set out concentrically. 
		   Our multiagent system is made up of a set of agents named darkening agents and lightening agents. 
		   These agents follow either the light rings or the dark rings and act on the image. 
		   Their actions aim to reinforce the rings by stressing the contrasts allowing, thus, a reliable detection of these rings, 
		   even if they are discontinuous. Each agent has three sensors allowing it to obtain information about the environment. 
		   The sensor ar made up of unit sensors returning the value of a pixel. The three sensors of an agent are: 
		   (1) a unit sensor allowing the agent to know if it is located on an already detected stria, 
		   (2) two disk-shaped sensors made up of unit sensors. 
		   These two sensors return the sum of their unit sensors. They are located in front of the agent and distant one from the other. 
		   Those two disk-shaped sensors are used for determining the movements of the agent and, therefore, for detecting the rings. 
		   An agent, indeed, always tries to move where the values returned by the senors is minimal. 
		   The suggested multiagent system has shown great robustness and adaptability, for it can detect strias, 
		   even if they are discontinuous and the image noisy.}

		 model (LDBB) based on a paramtric B-spline representation. The originality of this approach lies in the basic structure of the model, in the way it
		 operates, and in the expression of a new local driving force. This model evolves by small local deformations, through its control point displacement,
		 proportionally to a local resistance. In addition, it allows the use of high level information that constraint the bubble during its evolution. This model
		 presents a low noise and texture sensitivity. An application to fish otolith images is presented to illustrate model efficiency.}
