Abstract	La diversité des problématiques de manipulations de connaissances spatiales met en relief la multiplicité des méthodes de raisonnements et la difficulté de les unifier dans un raisonnement type, qui serait susceptible de s'appliquer à tous les cas de figures. En d'autres termes serait-il possible d'aboutir à un moteur unique d'inférence géométrique générique que l'on peut appliquer à n'importe quel type d'application? L'objectif est de décrire d'une manière succincte les différents modèles spatiaux géométriques et topologiques utilisés pour capter la richesse sémantique des objets spatiaux et surtout d'utiliser la puissance intensive et compréhensive d'inférence de ces modèles spatiaux géométriques et topologiques. Dans la perspective de développement d'outils dédiés aux raisonnements spatiaux, le travail de recherche publié dans cet article apportera une contribution dans les trois axes différents suivants: maîtrise des moyens de représentations selon les types d'applications, adaptation de la modélisation des objets spatiaux et manipulations et raisonnements spatiaux dans des contextes différents.

Titer	An Information System for Urban Spatial Analysis using Digital Cartography
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Many research works in automated cartography are carried out to solve problems related to social and urban human needs. In particular, a considerable attention has been devoted to the spatial aspect of cartographic information. In this paper, an information system for urban spatial analysis is presented. The system consists of two major components. An acquisition system for vectorising digital maps. A knowledge based system that uses computational geometry based rules for solving urban queries. Both spatial and non spatial urban queries are considered in this study. To solve such queries, the system uses a database containing both of textual information describing cartographic objects and a graphical information describing the spatial configuration of urban objects in maps. The proposed system outlines a method for urban spatial representing, modelling and reasoning that provide valuable intelligent aids for sorting out different spatial problems such as solving region queries, town-planning, analysing ground occupation, updating and archiving maps. Thus, the proposed system would be a major contribution for solving difficulties frequently encountered by large users in urban agencies.
Key Words	Spatial queries, Spatial reasoning, Urban spatial analysis, R-tree representation, Computational geometry and Database systems.

Titer	A Geographical Information System for Urban Spatial Analysis
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Geographic Information Systems (GIS) provide means of integrating information of different nature in a way that help us analyse and understand some of the most pressing urban problems related to modern cities we face today. Consequently, over the past decade a considerable attention has been devoted to the problem of designing and developing Geographical Information Systems (GIS), where spatial aspect is privileged. These efforts have led to the development of various GIS for urban needs which differ in the concepts, principles and ways of organising and reasoning about spatial information. These differences are mainly due to the nature of spatial objects and their properties related to semantic, geometric and topological aspects depending on application requirements. Therefore, designing an urban spatial information system is not an easy task.
Key Words	GIS, Urban spatial analysis, Geometric and Topological aspect.

Titer	Optimization of the indexing Space in the Geographical Information System
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	In order to speed up to their execution, space queries require the uses of specific access methods. For these needs, several methods are proposed: structures in grids, quaternary tree, and the right-angled tree. Therefore, in order to space speed up the research for objects and for much more efficient space query resolution, it is necessary to deal with optimal year space index. Now, this task requires has qualitative evaluation of the different index structures that strongly depends one the choices of the implementation, of the real dated, and the tested operations. Our objectifies in this paper is to suggest a technique of index optimization for the objects represented one either mono-to bush-hammer but multi-to bush-hammer map limiting it At the BASIC not operation. This technique is based on efficient approach with two phases, and focus mainly on the linear quadtrees flexibility linked to digital aspect of the representation and the research. The two phases are: the filtering that generates the objects candidate for of resolution has queries and the refining that operates directly one the objects issued from the first phase to form the result.
Key Words	Space indexing, Mono-to bush-hammer, Multi-bush-hammer, Grid, R+three, Linear-quadtree and Peano's curve.

Titer	GIS for Urban Spatial Analysis
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	During the last decade, various GIS for urban needs have been designed and developed. They differ in the way of organizing and reasoning about spatial information. This is mainly due to the nature of spatial objects and their properties related to semantic, geometric and topological aspects. In this paper, an urban information system for representing, modeling and manipulating urban objects is presented. The paper shows the interest of a topological model based on Rectangle-Tree (R-Tree) structure for solving most of urban spatial queries such as locating queries, neighborhood queries, distance queries and map-updating queries.
Key Words	Geographic information systems, Spatial queries, Spatial reasoning, Urban spatial analysis, Rectangle-tree representation and Database systems.

Abstract	In this paper, we present a parallel algorithm for edge detection based on Infinite Impulse Response filter (IIR filter). In particular, the Infinite size Symmetric Exponential Filter (ISEF) which is an optimal IIR filter and computationally efficient smoothing filter is studied. The proposed algorithm exploits efficiently all aspects of potential parallelism (spatial parallelism, temporal parallelism and systolism) inherent in the considered edge detection algorithms. The designed concurrent algorithm is expressed in terms of a collection of concurrent processes communicating and synchronizing in an efficient way in order to speed up the low-level operations.

Titer	GIS for the Management and the Follow-up of the Landslides of the Constantine City
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Slips are an old phenomenon. They are displacements of masses of grounds along the zone or slip surface sheared low thicknesses, influenced by a great number of factors geologic, hydro geologic, geotechnical, topographic and climatic. The management of the landslides is based mainly on the cards or the plans of the geographical areas on which the study goes. The manual realization of the cards requires a significant time, capacities and efforts due to the various encountered difficulties. Modifications require manual research and checks, which prove to be slow and expensive. Filing spends time and space. The actualization of the plans is difficult. Our objective is to develop a data-processing tool (GIS) of decision-making aid for the detection and the follow-up of landslides of the Constantine’s city in order to facilitate the follow-up of this phenomenon and the rational decision-making. This system will allow the implementation of a space data base, whose consultations will contribute to the comprehension of the phenomenon and especially to proceed to scenarios of simulations.

Titer	Modeling and Approaches of Spatial Ontologies for the Implementation of Prevention Systems of the Natural Risks « Landslides in the Town of Constantine
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	These last years, the phenomena of the natural risks became a preoccupation with a priority, in particular the landslides, which is a very significant phenomenon. The reduction of the risks caused by this last, requires a thorough knowledge of the seism, storms, floods as well as human, economic and environmental stakes. The natural risk management requires new monitoring systems of the significant zones in order to detect areas on which the study goes and to locate its progression. This approach is based on as permanent and precise observations as possible. The use of the GIS in the field of the prevention is of primary importance, as a tool for synthesis which gives access the geographical technology of analysis. The evaluation of the good decision as regards prevention of the natural risks passes by knowledge of interactions to short, average and long term, in order to maintain and to improve the state of, prevention and the maintenance alarm systems of the resources. For such reasons we will be in front of the challenges to present a reliable approach, by using new techniques, which are spatial ontologies and the systems multi agents, for the implementation of the systems of prevention of the natural risks. In this paper, we will deal with the problem of the landslides of the town of Constantine.

Abstract	Since a lot of years, the Biskra region endures problems bound to the desertification. One notes that the wilaya and especially the Biskra city are threatened by advancing it of the desert, and in particular in winter and in fall where the desertification factors are very strong. The research of an explanation concerning these different factors of desertification, and of the less their detection and their follow-up, became a priority for everybody in the region. Our objective is to develop a computer tool (Geographical Information System: “G.I.S”) of help to the decision for the detection and the follow-up of the desertification factors in the Biskra region to permit the follow-up of this phenomenon and especially to take the decisions that will impose themselves. This system is going to permit the setting in work of a data base spatial, whose consultations are going to help towards the understanding of the phenomenon and especially to conduct simulations scripts.

Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	The present paper treats the problem of the interoperability of the geographic information system (GIS) by an approach based on ontology. This last is conceived of a new manner that is characterized by an approach inspired of the architectures of the computers networking 3- third party (see figure 1). The adoption of such approach is justified by the objective of our conception that was the separation between the treatment of the operations and the one of the data, as well as the ontology plays here a role of intermediation to minimize heterogeneity and to unify the communication between the different GIS. Several processes have been added to complete and to strengthen the working of this ontology.

Abstract	The objective, in addition to the production of the geographical data, it is help to the decision. The geographical data bases created a level of abstraction of the real world, what moves away us of the reflection of the geographical card. Although the big Algerian south either very vast or rich, it remains under exploited. It is the reason for which, one was interested in statistics concerning the evolution of the distribution of the population of the Adrar region as well as the criteria influencing on her. So that the persons responsible of the development projects can intervene in the evaluation of the region urban space, they must be able to work on a system of geographical data processing of help to the decision. In this paper, we are going to present our project of realization of this system of information geographical SIG for the follow-up and the management of the urban data of the Adrar region via a data base geographical (spatial). It is based largely on the geographical region cards on which door the survey, and the manual realization of the cards requiring a lot of time and of the capacities important of storage. The user must be able to do the analyses and the spatial requests and finally to publish the reports giving account of the situations of simulations done.

Abstract	The mining geology is a part of applied geology that is about the useful mineral substances that they are metallic or no. It starts by the prospecting (mining research), until the discovery of economically exploitable layers. So that the mining geologist can intervene in the evaluation, the establishment of the technique of exploitation and treatment of ore, he must be able to work on a system of geographical data processing of help to the decision. In this paper, we are going to present our project of realization of this system of information geographical SIG for the follow-up and the management of the geology mining data of the Constantine region via a geographical (spatial) data base. It is based largely on the cards of the geographical regions on which door the survey, and the manual realization of the cards requiring a lot of time and of the capacities important of storage.

Abstract	L’objectif, en plus de la production des données géomatiques, c’est l’aide à la décision. Les bases de données géographiques ont créé un niveau d’abstraction du monde réel, ce qui nous éloigne du reflet de la carte géographique. Bien que le grand sud algérien soit très vaste et riche, il reste sous exploité. C’est la raison pour laquelle, on s’est intéressé aux statistiques concernant la l’évolution de la répartition de la population de la wilaya d’Adrar ainsi que les critères influant sur elle. Pour que les responsables des projets de développement puissent intervenir dans l'estimation de l’espace urbain de la wilaya, ils doivent pouvoir travailler sur un système d’informatique géographique d’aide à la décision. Dans ce papier, nous allons présenter notre projet de réalisation de ce système d’information géographique « SIG » pour le suivi et la gestion des données urbaines de la wilaya d’Adrar via une base de données géographiques (spatiales). Il est basé en grande partie sur les cartes géographiques de la wilaya sur lesquelles porte l’étude, et la réalisation manuelle des cartes nécessitant beaucoup de temps et des capacités importantes de stockage. L’utilisateur doit pouvoir effectuer des analyses et des requêtes spatiales et enfin éditer des rapports rendant compte des situations de simulations effectuées.

Abstract	Nous avons traité dans le présent article, le problème de l’interopérabilité des systèmes d’informations géographiques (SIG) par une approche basée sur une ontologie. Cette dernière elle est conçue d’une nouvelle manière, qui se caractérise par une approche inspirée des architectures des réseaux informatiques 3-Tiers. L’adoption d’une telle approche est justifiée par l’objectif de notre conception qui était la séparation entre le traitement des opérations et celui des données, ainsi que l’ontologie joue ici un rôle d’intermédiation pour minimiser l’hétérogénéité et unifier le discours entre les différents systèmes d’Information géographiques. Plusieurs processus ont été ajoutés pour compléter et consolider le fonctionnement de cette ontologie.

Titer	Nouvelle approche de recherche d’images aériennes par le contenu dans une base de données cartographiques
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Le sujet de recherche exposé dans ce papier concerne la recherche par le contenu des images dans une base de données cartographique. L'augmentation des capacités de stockage et l'évolution des techniques de compression ont engendré une explosion de la quantité d'information numérisée. Leur informatisation ouvre un vaste champ d'applications. Dans ce cadre, nous nous sommes intéressés plus particulièrement au problème de l’indexation d’une base de données cartographique par une recherche du contenu d’une image aérienne (on s’intéresse qu’à l’aspect extraction de routes), et dont voici les principales étapes : l'extraction non supervisée des réseaux linéiques (dans notre cas on s’intéresse qu’aux routes) à partir d'images aériennes. Nous utilisons dans cette étape une modélisation du réseau linéique par un processus dont les objets sont des segments interagissant entre eux. Le modèle apriori est construit de façon à exploiter au mieux la topologie du réseau recherché au travers de potentiels fondés sur la qualité de chaque interaction. Les propriétés radio métriques sont prises en compte dans un terme d'attache aux données fondé sur des mesures statistiques; comme seconde phase, on procède à la reconstitution d’une grille des surfaces planes avec comme méthode de classification qui respecte les relations spatiales entre les points (c.à.d. information de voisinage). Nous appliquerons les trois méthodes suivantes : la méthode du voisin le plus proche, l’analyse discriminante linéaire (ADL) et l’analyse discriminante quadratique (ADQ) et machines à vecteur de support (SVM). Par l’application de ces trois méthodes, nous aurons une carte de classes labellisées des régions par contours actifs de notre image requête. Pour déterminer les classes qui seront utilisé comme entrées dans la prochaine phase nous tiendrons en compte que les classes de régions connexes et nous éliminons les classes de régions discontinues. Troisième phase : Indexation de la base de données cartographique à travers l’appariement de la grille des surfaces connexes obtenues. Ceci encalculant les surfaces relatives de chaque classe de surface et qui seront introduits comme vecteurs de caractéristiques pour chaque surface (on considère que chaque surface ne peut pas avoir plus de 8 arêtes connexes). Et donc, Nous adoptons l'approche de segmentation en régions qui fournit une approximation naturelle des objets. Pour satisfaire les besoins d'un système de recherche par régions, nous proposons une approche de segmentation rapide et non supervisée (par des réseaux de neurones) pour détecter des régions grossières et pertinentes pour l'utilisateur. Quatrième Phase : Restitution des emplacements possibles trouvés par notre moteur de l’image requête.

Abstract	The users are more and more demanding towards their software. They wait for a big reliability, for a number ceaselessly increasing of services, the respect for constraints of conviviality, for cost Therefore, the size and the complexity of the software increases. The current techniques do not allow to protect us from problems of conception, Now they are more expensive to us to detect them during the phase of the implementation or the test that at the time of the conception. That is why we need a high-level modeling of the system, which would allow us to analyze the organization between the various elements of calculation and the interactions between these elements. This level of abstraction is called the architecture of the software, which serves for modeling, analyze and test the most important aspects of the development to obtain software more safe and in a faster way. The idea leads us to think of a work on the conception and the development of a new language of description of architecture ( ADL), based on a formal model in the mathematical sense, and focuses on the formal description of the software architectures (the structure and the behavior- Dynamics, time of execution).

Titer	A new selective encryption of JPEG2000 code stream for confidential images transmission
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	In this paper, a novel selective encryption image scheme based on JPEG2000 is proposed, which encrypts only the code-blocks corresponding to some sensitive precincts. In order to improve the security level we introduce the permutation of code blocks contributing in the selected precincts. Symmetric encryption AES with CFB mode is used to encrypt swapped code blocks. The idea of combining permutation and selective encryption is used in order to minimize the amount of processed data encryption while ensuring the best possible degradation through the permutation. The proposed process encryption doesn’t introduce superfluous JPEG2000 markers in the protected code stream, i.e, the protected code stream format is compliant to JPEG2000 code stream one. It keeps file format and compression ratio unchanged and doesn’t degrade the original error robustness. The proposed scheme works with any standard ciphers and introduces negligible computational cost.

Titer	An encryption scheme for JPEG2000 code stream based on packets header information and data encryption for confidential medical images transmission
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university, Research Center CDTA of Algiers and El Oued university
Abstract	In this paper, a novel selective encryption scheme for JPEG2000 code stream is proposed. Many of proposals format compliant encryption schemes for JPEG2000 that have been made encrypt packet body data, but leave header packet in plaintext. Our proposed scheme encrypts code-blocks data corresponding to some sensitive precincts. This encryption is combined to a cyclic permutation of all packets headers in the bit stream. Actually, in the JPEG2000 code stream, packet header information is specific to the visual content, and it is can be used as a fingerprint of the code stream. The proposed process doesn’t introduce superfluous JPEG2000 markers in the protected code stream, i.e, the protected code stream format is compliant to JPEG2000 code stream one. It keeps file format and compression ratio unchanged and doesn’t degrade the original error robustness. The proposed scheme works with any standard ciphers and introduces negligible computational cost.

Abstract	In all domains, the on line stake of an interactive cartography is essential for the diffusion of information by the general public. The on line stake of a cartography on Internet can take several shapes. It can be about static cards, as picture. Interactions with the user can be added on the produced cards. It is about functions of displacements; zoom as well as functions of presentation (display of information, change of scale, global view). To this level, we try as possible to interrogate, by selection, of the objects represented on the card (townships, establishments). This level is called the fluent Web mapping. The dynamic cartography is used when the represented information is constantly renewed and distant. In this case, a server is in real time about the data bases actualized in order to offer the users of the answers to their particular requests. The functions proposed in this case come closer of those of GIS software (acquirement, manipulation, management and treatment of geographical data). In our paper, we are going to explore the possibilities of dynamic cartography integration on the Web.

Titer	A new methodology for the development of computer ontologies
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	In this paper we propose a new methodology for construction of ontology, which is based on a set of mapping rules from a conceptual schema (Entity- Relationship) and its logical model (relational model) to a conceptual ontology. The proposed methodology consists of three big steps, which are, the Transformation (mapping), the Formalization and the Codification. The crucial step in the process of this methodology, is the transformation, this last is based on an automatic extraction of information (such as entities, the relationship between them, their properties, the cardinalities,..) from a conceptual model ER , its corresponding relational schema, and the data stored in the database (the extensional schema) to create a conceptual ontology. The idea proposed in this paper has several objectives and can be exploited in many areas, among other is to minimize the manual work for the extraction of relevant terms on a domain of discourse, the second is facilitating the migration of an existing domain based on a traditional conceptual approach (entity relationship) to another solution based on an ontological approach, while retaining the principle of the first domain.

Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	The important success of the mobile systems of telecommunication motivates the suppliers of service to be reflected about enormous means of investments for infrastructures of network. The conception of big cellular networks is a complex problem, which turns around a big impact: the quality of the service and the cost of the network. With the continuous and fast growth of the traffic of communication, the large-scale planning becomes more and more difficult. This need is now more pointed with the evolution of phone networks (GSM), because of the biggest complexity of the system and the number of parameters which must be considered. In this subject, the solutions of the problems of dynamic optimization, Multi criteria associating the financial criteria (cost of the network), the technical criteria (insurance, availability) are developed in a context and the criteria of sale (quality of service). The interest of meta heuristics (methods of optimization) is based on their capacity to find the effective solutions in a reasonable time. But with objective multi-problems, the efficiency of meta heuristics can be compromised. Consequently, in this context it is necessary to integrate these methods into more general arrangements to develop more effective methods. For such reasons we are going to present an approach based on the Multi-Agents Systems (MAS) and the spatial ontologies, to conceive methods adaptive automobile which can react to the shape of the problem.

Titer	Modelling and Approaches of Spatial Ontologies for the Implementation of Prevention System of the natural Ricks : landslides in the Town of Constantine
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	These last years, the phenomena of the natural risks became a preoccupation with a priority, in particular the landslides, which is a very significant phenomenon. The reduction of the risks caused by this last, requires a thorough knowledge of the seism, storms, floods as well as human, economic and environmental stakes. The natural risk management requires new monitoring systems of the significant zones in order to detect areas on which the study goes and to locate its progression. This approach is based on as permanent and precise observations as possible. The use of the GIS in the field of the prevention is of primary importance, as a tool for synthesis which gives access the geographical technology of analysis. The evaluation of the good decision as regards prevention of the natural risks passes by knowledge of interactions to short, average and long term, in order to maintain and to improve the state of, prevention and the maintenance alarm systems of the resources. For such reasons we will be in front of the challenges to present a reliable approach, by using new techniques, which are spatial ontologies and the systems multi agents, for the implementation of the systems of prevention of the natural risks. In this paper, we will deal with the problem of the landslides of the town of Constantine.

Titer	Estimation of anger, sadness and fear expressions intensity based on the belief theory
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	This article presents a new method to estimate the intensity of a human facial expression. supposing an expression occurring on a face has been recognized among the six universal emotions (joy, disgust, surprise, sadness, anger, fear), the estimation of the expression’s intensity is based on the determination of the degree of geometrical deformations of some facial features and on the analysis of several distances computed on skeletons of expressions. these skeletons are the result of a contour segmentation of facial permanent features (eyes, brows, mouth). The proposed method uses the belief theory for data fusion. the intensity of the recognized expression is scored on a three-point ordinal scale: "low intensity", "medium intensity" or " high intensity". Experiments on a great number of images validate our method and give good estimation for facial expression intensity. We have implemented and tested the method on joy, surprise and disgust and now we implement the same method on the following expressions: anger, fear and sadness.
Key Words	Facial expression, Intensity estimation and Belief theory.

The current techniques do not allow protecting us from problems of conception.

However techniques come from this domain, concentrate more on the expression of the relations inter-agents. The expression of the mobility from the point of view of the distributed systems is not described. A property acquired time, will allow processes to choose themselves to move on the sites of a network to work locally on the resources and be exchanged their interactions. Reason for which, we are going to propose in this paper a formalization which appeals to an algebra of process, which is π-calcul, to conceive systems automobile adaptive which can react to the shape of the problem.

Universities	Constantine 2 university and El Oued university
Abstract	In this paper, we propose a set of mapping rules between the conceptual model ER and the corresponding relational database schema towards ontology. The rules that we propose are divided into two categories, those who transform the ER schema and others transform the relational database schema, the two complement each other to build an ontology representing a new view of reality perceived. The purpose of this work is to provide users with conventional systems, the convenience of migrating to an ontological approach without loss of information with an opportunity to enrich their systems, while retaining the principle of running the old system. More migration, our application has the potential to create new information systems based on an ontology without the user is connoisseur of philosophy ontological, while giving him the impression that works in an ER environment.

Abstract	In recent years, wireless communication systems have experienced tremendous growth, especially in broadcasting, television or handheld computers to the new generation with Web access (UMTS, GPRS). Meanwhile, the techniques of radio are now crucial to a growing number of services. As a result, the size and complexity of applications increases. Current technology cannot protect us from design problems. That is why we need a high-level modeling, which we will analyze the organization between the different elements of the system and the interactions between them. The interest of multi-agent systems stems from the collective behavior produced by the interaction of several autonomous entities called agents and flexible, these interactions that revolve around cooperation, competition and coexistence between these agents. However, techniques from the field, focus more on the expression of inter-agents. The expression of the mobility point of view of distributed systems is not described. A property once acquired, will allow the process to choose for themselves to move on the sites of a network to work locally on the resources and make their exchange interactions. Why we propose in this paper a formalization that uses a process algebra, which is the π-calculus to develop self-adaptive systems that can respond to the form of the problem.

Abstract	Au cours de ces dernières années, les systèmes de communication hertziens ont connu une croissance exceptionnelle, notamment dans la radiodiffusion. Ce besoin est maintenant bien plus aigu avec l’évolution des réseaux téléphoniques (GSM), en raison de la plus grande complexité du système et du nombre de paramètres qui doivent être considérés. Parallèlement, les techniques de radiocommunication revêtent désormais une importance cruciale pour un nombre croissant de services. . La conception de grands réseaux cellulaires est un problème complexe, qui tourne autour d’un grand impact : la qualité du service et le coût du réseau. Avec la croissance continue et rapide du trafic de communication, la planification à grande échelle devient de plus en plus difficile. Dans ce sujet, la solution des problèmes d’optimisation, sont développées dans un contexte multicritères associant les critères financiers (coût du réseau), les critères techniques (assurance, disponibilité) et les critères de vente (qualité de service). Par conséquent, dans ce contexte il est nécessaire d'intégrer ces outils d'optimisation dans des arrangements plus généraux afin de développer des méthodes bien plus efficaces. Pour de telles raisons nous nous retrouverons devant le défis de présenter une fiable approche, en utilisant de nouvelles techniques, qui sont les ontologies spatiales et les systèmes multi agents, afin de concevoir les méthodes auto adaptatives qui peuvent réagir à la forme du problème.

Titer	Toponym Disambiguation by Arborescent Relationship
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	A reference to a place in the geographic space can be formal based on the spatial coordinates, or informal, that we use in natural language using toponyms (place names). The informal representation is ambiguous: a toponym can represent multiple locations. This ambiguity has made an issue the conversion of toponyms to a unique formal representation. Toponym disambiguation in text is the task of assigning a unique location to an ambiguous place name in a given context. Several toponym disambiguation heuristics assume a geographical proximity between the toponyms of the same context. This proximity can be in term of spatial distance or in term of arborescent relationship, i.e. Proximity in the hierarchical tree of the world places. This paper presents a new toponym disambiguation heuristic in text based on the quantification of the arborescent proximity between toponyms. Our method outperforms the stat of the art methods compared with it using geosemcor corpus.

Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university, El Oued university and SUPELEC France
Abstract	Searching for information on the Web engages the user in a process of interrogating and querying the chosen search engine. However, the initial user's query rarely returns a result that satisfies his need for information. The reformulation of the initial query is to modify its terms in order to return a result that better meets the user’s needs. In this paper we propose a contextual query reformulation system that takes user’s context into consideration via his profile, thus we identify the parts of the context to be used to assist in the contextual reformulation and we show how the user’s profiles are used to catch the context, we present also the proposed architecture and the developed prototype.

Titer	Exact method for resolving the Q3AP problem on calculation grid
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Quadratic assignment to three dimensions (Q3AP) is one of the most difficult of problems. Combinatorial Optimization, this problem is NP-complete and has several applications in data transmissions. Its exact resolution pass by the enumeration of a very broad search tree that contains a billion summits for instances of size medium. The resolution optimally large instances of the problem require implementing in Work of the complex methods requiring more than power of calculation. Currently, with the growth of calculation grids, many parallel models for exact methods have been proposed. For a good grids environmental exploitation, the initial problem is divided into many units of work. These are then distributed on a thousand of processors on the grid. The objective is to push the more far as possible the exact resolution Q3AP. Large scale tests on the Q3AP are still in perspective.

Titer	From Multi Agents and π-Calcul towards a dynamic architecture for optimizing cellular network for mobile phone
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	The conception of big cellular networks is a complex problem, which turns around a big impact: the quality of the service and the cost of the network. With the continuous and fast growth of the traffic of communication, the large-scale planning becomes more and more difficult. This need is now more pointed with the evolution of phone networks (gsm), because of the biggest complexity of the system and the number of parameters which must be considered. In this subject, the solutions of the problems of dynamic optimization, multicriteria associating the financial criteria (cost of the network), the technical criteria (insurance, availability) are developed in a context and the criteria of sale (quality of service). As a result, the size and complexity of applications increases. Current technology can not protect us from design problems. That is why we need a high-level modeling, which we will analyze the organization between the different elements of the system and the interactions between them. The interest of multi-agent systems stems from the collective behavior produced by the interaction of several autonomous entities called agents and flexible, these interactions that revolve around cooperation, competition and coexistence between these agents. However, techniques from the field, focus more on the expression of inter-agents. The expression of the mobility point of view of distributed systems is not described. A property once acquired, will allow the process to choose for themselves to move on the sites of a network to work locally on the resources and make their exchange interactions. Why we propose in this paper a formalization that uses a process algebra, which is the π-calculus to develop self adaptive systems that can respond to the form of the problem.

Titer	Toponym Disambiguation by Arborescent relationships
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	A reference to a place in the geographic space can be formal based on the spatial coordinates, or informal, that we use in natural language using toponyms (place names). The informal representation is ambiguous: a toponym can represent multiple locations. This ambiguity has made an issue the conversion of toponyms to a unique formal representation. Toponym disambiguation in text is the task of assigning a unique location to an ambiguous place name in a given context. Several toponym disambiguation heuristics assume a geographical proximity between the toponyms of the same context. This proximity can be in term of spatial distance or in term of arborescent relationship, i.e. Proximity in the hierarchical tree of the world places. This paper presents a new toponym disambiguation heuristic in text based on the quantification of the arborescent proximity between toponyms. Our method outperforms the stat of the art methods compared with it using geosemcor corpus.
Key Words	Toponyms disambiguation, Arborescent proximity, Geographical density and Referent hierarchical path

Abstract	We present in this paper, the general description of a classical process of character recognition, and subsequently we describe our contribution for a new process that is characterized by a step of creating of domain ontology, representing the Latin alphabet in the form of concepts, where each concept represents a grapheme (features). In this work we consider that there is a robust extraction module of primitives that will serve us to instantiate our ontology, by the different graphemes and their spatial relationships that exist in the processed enriching it by new specific spatial relationships. Our process represents a new approach in the domain of character recognition, we have not developed a final product but our idea is promising in this domain.

Titer	The Danger Theory Applied to Vegetal Image Pattern Classification
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Artificial Immune Systems (AISs) are a type of intelligent algorithm inspired by the principles and processes of the human immune system. Despite the successful implementation of different AISs, the validity of the paradigm "self non self" have lifted many questions. The Danger theory was an alternative to this paradigm. If we involve its principles, the AIS is being applied as a classifier. However, image classification offers new prospects and challenges to data mining and knowledge extraction. It is an important tool and a descriptive task seeking to identify homogeneous groups of objects based on the values of their attributes. In this paper, we describe our initial framework in which the danger theory was apprehended by the Dendritic cells algorithm is applied to vegetal image classification. The approach classifies pixel in vegetal or soil class. Experimental results are very encouraging and show the feasibility and effectiveness of the proposed approach.

Titer	A Method for Plant Classification Based on Artificial Immune System and Wavelet Transform
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university, CHUC of Constantine and El Oued university
Abstract	Leaves recognition plays an important role in plant classification. Its key issue lies in whether selected features are stable and have good ability to discriminate different kinds of leaves. In this paper, we propose a novel method of plant classification from leaf image set based on artificial immune system (AIS) and wavelet transforms. AISs are a type of intelligent algorithm;they emulate the human defense mechanism and they use its principles, to give them the power to be applied as a classifier. In addition, the wavelet transform offers fascinating features for texture classification. Experimental results show that using artificial immune system and wavelet transform to recognize leaf plant image is possible, and the accuracy of recognition is encouraging.
Key Words	Artificial immune system (AIS), Dendritic cell algorithm (DCA), Digital wavelet transform and Leaves classification.

Abstract	Classical approaches for evaluating information retrieval tools have limitations and shortcomings, particularly regarding to the consideration of the user, the manner in which these approaches measure the adequacy between the user's query and the returned documents, and the consideration of the search tool characteristics. This critical finding prompted our reflections for the exploitation of contextual elements around the user, the query and the search tool during the evaluation process. This paper presents a new approach based on three complementary levels of context for evaluating information retrieval tools. The experiments gives at the end of this article has shown the applicability for the proposed approach to real research tools. The tests were performed with the most popular searching engine (i.e. Google, Bing and Yahoo) selected in particular for their high selectivity. The results have revealed that the evaluation of search engines at three different levels of context is a promising way to diagnose the performance, characteristics and behavior of these engines and the relevance of the results that they return.

Abstract	The crucial role of the evaluation in the development of the information retrieval tools is useful evidence to improve the performance of these tools and the quality of results that they return. However, the classic evaluation approaches have limitations and shortcomings especially regarding to the user consideration, the measure of the adequacy between the query and the returned documents and the consideration of characteristics, specifications and behaviors of the search tool. Therefore, we believe that the exploitation of contextual elements could be a very good way to evaluate the search tools. So, this paper presents a new approach that takes into account the context during the evaluation process at three complementary levels. The experiments gives at the end of this article has shown the applicability of the proposed approach to real research tools. The tests were performed with the most popular searching engine (i.e. Google, Bing and Yahoo) selected in particular for their high selectivity. The obtained results revealed that the ability of these engines to rejecting dead links, redundant results and parasites pages depends strongly to how queries are formulated, and to the political of sites offering this information to present their content. The relevance evaluation of results provided by these engines, using the user's judgments, then using an automatic manner to take into account the query context has also shown a general decline in the perceived relevance according to the number of the considered results.

Abstract	In this paper, we present a general description of an ontology, describing the different character of Latin language, which is semantically annotated by a domain expert. This ontology represents the typographical description of the analyzed and processed document, by a set of concepts where each concept, represents a grapheme of character and must be designated by a unique number denoting its position or its localization in the document. The relationship between, two graphemes is of spatial type; it represents the connectivity between graphemes in the document to facilitate the recognizing process of characters. Our ontology is generic and can support other languages by enriching it by new specific spatial relationships.

Abstract	In several practical application domains, combinatorial optimization problem (POC) is an very important. Due to the difficulty of problems optimization and many practical applications that can take the formula of a POC. Currently the major challenge is to resolve a generic POC large, where the use of meta-heuristic is recommended. Their approach "A unique solution", based on the appearance of intensification, quickly gives a good solution, but may be trapped by a local optimum. This above is avoided with the appearance of diversification provided by approach "to the population of solution", the latter has the disadvantage that found solution set is just an approximation of the optimum .this while we can see that the hybridization of two approaches can better guide the process of research to the optimal solution, the mechanism of parallelism is a computing power and can accelerate the process of optimization. To enter this hybridization gains parallel it offers in this paper an application of the latter on the QAP quadratic assignment.

Abstract	Interoperability is necessary for many applications in the field of geographic information systems and systemsofdecision support. It involves sharing and reuse of data from various heterogeneous information systems. Ontologies are emerging as an important solution to build a body of knowledge shared and reusable that support their interaction. They define the common terms of representation providing a shared understanding of scope among user groups. In this paper, we present a general framework for a new mediation system capable of managing semantic interoperability between different information systems, particularly in geographic information systems based on ontologies. We will apply certain techniques in our approach can ensure cooperation between ontologies see the data to achieve semantic interoperability, such as merging and mapping. They are used to allow data sharing between heterogeneous knowledge bases, information reuse of these bases and stop-loss information to ensure the cooperation of an interoperable information system.

Titer	Predator Prey Optimizer for Multimodal Medical Image Registration
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	In this paper we describe our approach to predator-prey optimizer (PPO), a form of particle swarm optimizer where new particles called predators are introduced. PPO has been proposed as an attempt to achieve better balance between exploration and exploitation abilities of a particle swarm optimizer. The objective of predator-prey optimization is to use predator particles to help avoiding premature convergence to sub-optimal solutions in particle swarm optimizers. The swarm particles (prey particles) are repelled by predators, which in turn are attracted to the best individuals in the swarm. The resulting interactions make total convergence less difficult to the swarm, maintaining diversity in the population. First results of this new approach on multimodal medical image registration are presented and the performance of the algorithm is compared to the performance of the standard particle optimizer.
Key Words	Prey optimization, Particle swarm optimization and Image registration.

Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university, El Oued university and SUPELEC France
Abstract	This work falls in the areas of information retrieval and semantic web, and aims to improve the evaluation of web search tools. Indeed, the huge number of information on the web as well as the growth of new inexperienced users creates new challenges for information retrieval; certainly the current search engines (such as Google, Bing and Yahoo) offer an efficient way to browse the web content. However, this type of tool does not take into account the semantic driven by the query terms and document words. This paper proposes a new semantic based approach for the evaluation of information retrieval systems; the goal is to increase the selectivity of search tools and to improve how these tools are evaluated. The test of the proposed approach for the evaluation of search engines has proved its applicability to real search tools. The results showed that semantic evaluation is a promising way to improve the performance and behavior of search engines as well as the relevance of the results that they return.

Titer	Towards spatio-Temporal Toponym Ontology to Assist in Geographic Information Retrieval
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	During the search for geographical information in web pages, people are geo-referred with toponyms (place names) instead the use of coordinates. The conceptions of places are often complicated ambiguous and different in different time. When gazetteers are utilized as background knowledge in geographic information retrieval (GIR), they are limited because of their poor geographic semantics. Therefore, there is a need to specify the place name to geospatial semantic knowledge. Ontologies play a key role in the development of semantic spatial search. We propose in this paper the design methodology for building the spatio-temporal toponym ontology based on the basic formal ontology (BFO) and the Algerian administrative division. The spatio-temporal toponym ontology includes geographic elements such as spatial relationships, concepts, terms and historical names related to a place, which can assist in GIR by expressing changes and time characteristics of the evolution of place names and providing factual and semantic reports to solving several common problems using free ontology editor tool protégé.

Abstract	La diversité des problématiques de manipulations de connaissances spatiales met en relief la multiplicité des méthodes de raisonnements et la difficulté de les unifier dans un raisonnement type, qui serait susceptible de s'appliquer à tous les cas de figures. En d'autres termes serait-il possible d'aboutir à un moteur unique d'inférence géométrique générique que l'on peut appliquer à n'importe quelle type d'application? L'objectif est de décrire d'une manière succincte les différents modèles spatiaux géométriques et topologiques utilisés pour capter la richesse sémantique des objets spatiaux et surtout d'utiliser la puissance intensive et compréhensive d'inférence de ces modèles spatiaux géométriques et topologiques. Dans la perspective de développement d'outils dédiés aux raisonnements spatiaux, le travail de recherche publié dans cet article apportera une contribution dans les trois axes différents suivants: maîtrise des moyens de représentations selon les types d'applications, adaptation de la modélisation des objets spatiaux et manipulations et raisonnements spatiaux dans des contextes différents.

Titer	Urban Spatial Analysis for Digital Cartography
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Digital cartography has been an active field of research for many years. In this paper, a method for urban spatial modeling and reasoning that provide valuable intellectual aids for sorting out different spatial problems is presented. In particular, the goal of this paper is to show the interest of a model based on Rectangle-trees (R-trees) for solving spatial map queries in digital cartography, where spatial aspect is privileged. By spatial queries here we mean : point-in- polygon queries, region queries and path queries. A knowledge based system that uses computational geometry based rules is employed for solving such queries.
Key Words	Spatial queries, knowledge based system, urban spatial analysis, R-tree representation and computational geometry.

Titer	Urban Spatial Analysis using R-trees
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	During the last decade, various GIS for urban needs have been designed and developed. They differ in the way of organising and reasoning about spatial information. This is mainly due to the nature of spatial objects and their properties related to semantic, geometric and topological aspects. In this paper, an urban information system for representing, modelling and manipulating urban objects is presented. The paper outlines a method providing a basis for valuable intelligent aids to solve problems such as land use planning, environmental assessment and demo-socio-economic analysis. In particular, the paper shows the interest of a topological model based on Rectangle-Tree (R-Tree) structure for solving most of urban spatial queries such as locating queries, neighbourhood queries, distance queries and map-updating queries.
Key Words	Geographic information systems, Spatial queries, Spatial reasoning, Urban spatial analysis, Rectangle-tree representation and Database systems.

Abstract	Si la maîtrise de la gestion des données alphanumériques, à l’aide de système de gestion de base de données, est très simple à mettre en œuvre. Elle n’est pas acquise pour les connaissances spatiales dont les composantes topologiques et géométriques sont les plus importantes. L’urbanisme est une des applications spatiales caractérisée par la manipulation d’une masse volumineuse d’objets spatiaux, multimédia et multi sources. D’où la complexité d’une exploitation manuelle de ces objets ayant une nature spécifique. Le recours des urbanistes à la cartographie automatique a donné lieu à un système d’analyse et de raisonnement spatial sur des objets urbains (S.A.R.S.O.U.), qui fait l’objet de notre article. Ce système doit disposer de concepts et d’outils capables d’exploiter la richesse sémantique des objets spatiaux, tels que : des formalismes de modélisation des connaissances spatiales urbaines, des modèles de représentation spatiale de ces connaissances, des méthodes d’indexation spatiale de ces connaissances et enfin d’outils mathématiques et surtout géométriques pour résoudre les requêtes spatiales. Le but de cet article est de présenter justement notre système S.A.R.S.O.U. développé en coopération scientifique avec des entreprises de la région de Constantine.

Titer	Modèle Numérique de Terrain par la Méthode de Triangulation de Delaunay avec Contraintes
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	L'objet de cet exposé porte sur la conception d'un Modèle Numérique de Terrain ou "M.N.T". à partir de réseaux irréguliers de triangles. A cet effet, nous proposons un algorithme de construction de la triangulation de Delaunay avec contraintes pour l'approximation et la description de la surface topographique. Cet algorithme appartient à la classe des algorithmes incrémentaux dans laquelle la triangulation est mise à jour localement à chaque ajout ou retrait de points et de lignes (représentation des caractéristiques linéaires de la surface). Il n'impose aucun ordre préétabli de saisie, ni de connaissance globale de l'échantillonnage avant triangulation. Enfin, pour exploiter et traiter notre modèle de triangulation, nous avons développé des procédures qui permettent de générer les courbes de niveau, de réaliser des calculs de volume et de la visualisation de terrain. Ce modèle montre une grande flexibilité pour dériver des informations à l'usage de diverses applications dans les systèmes d'informations géographiques ou "S.I.G".

Abstract	La diversité des problématiques de manipulations de connaissances spatiales met en relief la multiplicité des méthodes de raisonnements et la difficulté de les unifier dans un raisonnement type, qui serait susceptible de s'appliquer à tous les cas de figures. En d'autres termes serait-il possible d'aboutir à un moteur unique d'inférence géométrique générique que l'on peut appliquer à n'importe quelle type d'application? L'objectif est de décrire d'une manière succincte les différents modèles spatiaux géométriques et topologiques utilisés pour capter la richesse sémantique des objets spatiaux et surtout d'utiliser la puissance intensive et compréhensive d'inférence de ces modèles spatiaux géométriques et topologiques. Dans la perspective de développement d'outils dédiés aux raisonnements spatiaux, le travail de recherche publié dans cet article apportera une contribution dans les trois axes différents suivants: la maîtrise des moyens de représentations selon les types d'applications, l’adaptation de la modélisation des objets spatiaux; et les manipulations et raisonnements spatiaux dans des contextes différents.

Titer	Les structures fractales des objets urbains dans un SIG
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Sur le plan des grandes agglomérations et surtout des villes, la surface construite a souvent une forme irrégulière, en dépit des efforts des urbanistes pour promouvoir des formes plus compactes. L’ordre spatial interne des grandes agglomérations relève de la géométrie fractale. Cet article montre l’intérêt d’appliquer la géométrie fractale aux villes et aux réseaux de communication des zones urbaines. Ici, on va surtout focaliser notre attention sur l’analyse grossière de la structure de la forme des constructions en matière d’occupation des surfaces du sol (fractales de surface telles les tapis de Sierpinski), et ce à des échelles permettant l’analyse des agglomérations et des villes comme celle de Constantine.

Abstract	Depuis bien des années, la wilaya d’El Oued Souf souffre d’un gros problème de remontée des eaux en surface. On note que la wilaya et surtout la ville sont menacées par ce fléau, surtout en hiver où le gradient de remontée des eaux en surface par capillarité ne cesse d’augmenter. La recherche d’une explication concernant cette remontée des eaux en surface est devenue une priorité pour les autorités et les gens de la région. Notre objectif est de développer un outil informatique (SIG) d’aide à la décision pour le suivi de la remontée des eaux de la wilaya d’El Oued Souf pour permettre le suivi de ce phénomène naturel et artificiel. Ce système va permettre la mise en œuvre d’une base de données spatiales, dont les consultations vont aider à la compréhension du phénomène et surtout de procéder à des simulations.

Abstract	Depuis bien des années, la wilaya de Constantine souffre des problèmes de pollutions de nature diverse. On note que la wilaya et surtout la ville sont menacées par des maladies diverses, et en particulier en été où les pollutions industrielles et automobiles prennent des pics dangereux pour la santé de la population. La recherche d’une explication concernant ces pollutions, et du moins leur détection et suivi, sont devenus une priorité pour tout le monde de la région. Notre objectif est de développer un outil informatique (SIG) d’aide à la décision pour la détection et le suivi de diverses pollutions de la wilaya de Constantine pour permettre le suivi de ce phénomène et surtout de prendre les décisions qui s’imposeront. Ce système va permettre la mise en œuvre d’une base de données spatiales, dont les consultations vont aider à la compréhension du phénomène et surtout de procéder à des scénarios de simulations.

Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Nous avons traité dans le présent article, le problème de l’interopérabilité des systèmes d’informations géographiques (SIG) par une approche basée sur une ontologie. Cette dernière elle est conçue d’une nouvelle manière, qui se caractérise par une approche inspirée des architectures des réseaux informatiques 3-Tiers (cf. figure 1). L’adoption d’une telle approche est justifiée par l’objectif de notre conception qui était la séparation entre le traitement des opérations et celui des données, ainsi que l’ontologie joue ici un rôle d’intermédiation pour minimiser l’hétérogénéité et unifier le discours entre les différents systèmes d’Information géographiques. Plusieurs processus ont été ajoutés pour compléter et consolider le fonctionnement de cette ontologie.

Titer	Nouvelle approche de recherche d’images aériennes par le contenu dans une base de données cartographiques
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Le sujet de recherche exposé dans ce papier concerne la recherche par le contenu des images dans une base de données cartographique. L'augmentation des capacités de stockage et l'évolution des techniques de compression ont engendré une explosion de la quantité d'information numérisée. Leur informatisation ouvre un vaste champ d'applications. Dans ce cadre, nous nous sommes intéressés plus particulièrement au problème de l’indexation d’une base de données cartographique par une recherche du contenu d’une image aérienne (on s’intéresse qu’à l’aspect extraction de routes), et dont voici les principales étapes : l'extraction non supervisée des réseaux linéiques (dans notre cas on s’intéresse qu’aux routes) à partir d'images aériennes. Nous utilisons dans cette étape une modélisation du réseau linéique par un processus dont les objets sont des segments interagissant entre eux. Le modèle a priori est construit de façon à exploiter au mieux la topologie du réseau recherché au travers de potentiels fondés sur la qualité de chaque interaction. Les propriétés radio métriques sont prises en compte dans un terme d'attache aux données fondé sur des mesures statistiques. Comme seconde phase, on procède à la reconstitution d’une grille des surfaces planes avec comme méthode de classification qui respecte les relations spatiales entre les points (c.à.d. information de voisinage). Nous appliquerons les trois méthodes suivantes : la méthode du voisin le plus proche, l'analyse Discriminante Linéaire (ADL) et l’Analyse Discriminante Quadratique (ADQ), les machines à vecteur de support (SVM). Par l’application de ces trois méthodes, nous aurons une carte de classes labellisées des régions par contours actifs de notre image requête. Pour déterminer les classes qui seront utilisé comme entrées dans la prochaine phase nous tiendrons en compte que les classes de régions connexes et nous éliminons les classes de régions discontinues. Troisième phase : Indexation de la base de données cartographique à travers l’appariement de la grille des surfaces connexes obtenues. Ceci en calculant les surfaces relatives de chaque classe de surface et qui seront introduits comme vecteurs de caractéristiques pour chaque surface (on considère que chaque surface ne peut pas avoir plus de 8 arêtes connexes). Et donc, Nous adoptons l'approche de segmentation en régions qui fournit une approximation naturelle des objets. Pour satisfaire les besoins d'un système de recherche par régions, nous proposons une approche de segmentation rapide et non supervisée (par des réseaux de neurones) pour détecter des régions grossières et pertinentes pour l'utilisateur. La quatrième phase consiste à la restitution des emplacements possibles trouvés par notre moteur de l’image requête.
Key Words	Indexation de bases de données, Extraction de routes, Appariement d’images, Segmentation en régions, Contours actifs, Voisin le plus proche, Analyse discriminante linéaire, Analyse discriminante quadratique et Machines à vecteur de support (SVM).

Abstract	La géologie minière est une partie de géologie appliquée qui traite des substances minérales utiles qu'elles soient métalliques ou non. Elle débute par la prospection (recherche minière), jusqu'à la découverte de gisements économiquement exploitables. Afin que le géologue minier puisse intervenir dans l'estimation, l'établissement de la technique d'exploitation et de traitement du minerai, il doit pouvoir travailler sur un système d’informatique géographique d’aide à la décision. Dans ce papier, nous allons présenter notre projet de réalisation de ce système d’information géographique « SIG » pour le suivi et la gestion des données de la géologie minière de la région de Constantine via une base de données géographiques (spatiales). Il est basé en grande partie sur les cartes des régions géographiques sur lesquelles porte l’étude, et la réalisation manuelle des cartes nécessitant beaucoup de temps et des capacités importantes de stockage. L’utilisateur doit pouvoir effectuer des analyses et des requêtes spatiales et enfin éditer des rapports rendant compte des situations de simulations effectuées.

Titer	3D Reconstruction of Urban Objects
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	The urban application needs more and more the 3D geometric model of certain parts of city or of the whole city: planning urban, new constructions, interactive virtual visits of a city, etc. But in a lot of cases it’s not necessary to have very detailed and voluminous model in memory size and then not easy to handle. This is why our project can be really useful to permits the 3D simplified reconstruction of buildings. The objective of our work consists in the construction and development of a tool permitting exactly the reconstruction in three dimensions of urban zones and has for vocation to apply to all people having need of a simplified modeling of urban zones. Thus, the architect, the urbanist or the engineer in civil genius can found in this tool an instrument to the clarification of their projects. The idea of this project is the following: the conception of an application able to represent buildings in 3D, methods and approaches were multiple, our choice was determine by feasibilities criteria (time and available data).

Abstract	The users are more and more demanding towards their software. They wait for a big reliability, for a number ceaselessly increasing of services, the respect for constraints of conviviality, for cost … Therefore, the size and the complexity of the software increases. The current techniques do not allow to protect us from problems of conception, Now they are more expensive to us to detect them during the phase of the implementation or the test that at the time of the conception. That is why we need a high-level modeling of the system, which would allow us to analyze the organization between the various elements of calculation and the interactions between these elements. This level of abstraction is called the architecture of the software, which serves for modeling, analyze and test the most important aspects of the development to obtain software more safe and in a faster way. The idea leads us to think of a work on the conception and the development of a new language of description of architecture ( ADL), based on a formal model in the mathematical sense, and focuses on the formal description of the software architectures (the structure and the behavior- Dynamics, time of execution).
Key Words	Software architecture, Language formal language, Higher order logic and System of check of proofs.

Laboratory	MISC Laboratory of Constantine

Abstract	Dans tous les domaines, la mise en ligne d’une cartographie interactive est essentielle pour la diffusion de l’information auprès du grand public. Tous les éléments, constitutifs d'un objet géographique, sont représentés par des conventions, avec des symboles. Chaque élément est représenté à l'échelle de la réalité. La mise en ligne d'une cartographie sur Internet peut prendre plusieurs formes. Il peut s’agir de cartes statiques, sous forme d'image. Des interactions avec l'utilisateur peuvent être ajoutées sur les cartes produites. Il s'agit de fonctions de déplacements, de zoom ainsi que de fonctions de présentation (affichage d’informations, changement d'échelle, vue globale). A ce niveau, il est aussi possible d'interroger, par sélection, des objets représentés sur la carte (communes, établissements). Ce niveau est couramment appelé Web mapping. La cartographie dynamique est utilisée lorsque l'information à représenter est constamment renouvelée ou si l'étendue géographique de la zone à couvrir est grande. Dans ce cas, un serveur traite en temps réel des bases de données actualisées afin d'offrir aux utilisateurs des réponses à leurs requêtes particulières. Les fonctions proposées dans ce cas se rapprochent de celles d'un logiciel de SIG (acquisition, manipulation, gestion et traitement de données géographiques). Dans ce papier, on va explorer la possibilité d’intégration d’une cartographie dynamique sur le Web.

Abstract	The main objective aimed by this article, is the construction of an urban ontology for the management automated of the publicity panels implanted along roads and the public voices. This article shows how the GIS domain can take advantage of new approaches of modeling and conceptualization based ontology and the advantages brought by this last. The service of the public road network of the Constantine city (Algeria country) in which we were interested in our case study, gave us a general idea on the problems concerning the decision making towards critical situations as the accidents, the optimization of the roads (ways) exploitation, the publicity panel management and all underlying problems. Orientation and the good organization of the road also make a primordial preoccupation of the service concerned. Our objective in this article is to assure a better use of the geographical information, by the good representation and interpretation of this information what also implies the understanding and the hold of the good decision.

Titer	Sift detectors for matching areal images in reduced space
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	In this paper we propose a novel approach for matching cartographic images over detecting interest points invariant to scale and affine transformations. Our scale and affine invariant detectors are based on the following recent results: Interest points extracted with the SIFT detector which is adapted to affine transformations and give repeatable results (geometrically stable). This provides a set of distinctive points which are invariant to scale, rotation and translation as well as robust to illumination changes and limited changes of viewpoint. The characteristic scale determines a scale invariant region for each point. The characteristic scale and the affine shape of neighborhood determine an affine invariant region for each point. We apply an unsupervised classification to reduce the space of sets of interest points by using weighted bipartite graph matching in solving the point correspondence. Diffusion map: projection of the bipartite graph in a reduce space on which we apply K-means to classify the representatives clusters.

Abstract	L’important succès des systèmes mobiles de télécommunication motive les fournisseurs de service à réfléchir à d’énormes moyens d’investissements pour des infrastructures de réseau. La conception de grands réseaux cellulaires est un problème complexe, qui tourne autour d’un grand impact : la qualité du service et du coût du réseau. Avec la croissance continue et rapide du trafic de communication, la planification à grande échelle devient de plus en plus difficile. Ce besoin est maintenant bien plus aigu avec l’évolution des réseaux téléphoniques (GSM), en raison de la plus grande complexité du système et du nombre de paramètres qui doivent être considérés. Dans ce sujet, les solutions des problèmes d’optimisation dynamique, sont développées dans un contexte multicritères associant les critères financiers (coût du réseau), les critères techniques (assurance, disponibilité) et les critères de vente (qualité de service). L’intérêt des métaheuristiques (méthodes d’optimisation) est basé sur leur capacité de trouver les solutions efficaces dans un temps raisonnable. Mais avec des problèmes multi objectifs, l'efficacité des métaheuristiques peut être compromise. Par conséquent, dans ce contexte il est nécessaire d'intégrer ces méthodes dans des arrangements plus généraux afin de développer des méthodes bien plus efficaces. Pour de telles raisons nous allons présenter une approche basée sur les systèmes multi agents et les ontologies spatiales, afin de concevoir des méthodes auto adaptive qui peuvent réagir à la forme du problème.

Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	In this paper we propose a new methodology for construction of ontology, which is based on a set of mapping rules from a conceptual schema (Entity-Relationship) and its logical model (relational model) to a conceptual ontology. The proposed methodology consists of three big steps, which are, the Transformation (mapping), the Formalization and the Codification. The crucial step in the process of this methodology, is the transformation, this last is based on an automatic extraction of information (such as entities, the relationship between them, their properties, the cardinalities,..) from a conceptual model ER , its corresponding relational schema, and the data stored in the database (the extensional schema) to create a conceptual ontology.
Key Words	Information system, Entity-relation model, Ontology, Migration and Mapping rules.

Universities	Constantine 2 university and El Oued university
Abstract	Quantifier la précision lors d’exécution d’un geste peut servir à observer le rétablissement chez un patient en phase de rééducation tout comme permettre l’apprentissage de l’écriture chez un enfant. Dans le domaine des interfaces homme machine, elle peut aider à quantifier l’aisance qu’aurait un utilisateur en effectuant un geste de control, et le degré d’attention qu’il accorde en exécutant cette tache. A notre connaissance il existe qu’un seul modèle composé pour quantifier la variabilité dans l’exécution, basé sur la variation en flexion et d’étirement. Dans ce papier, on s’est donné deux objectifs à atteindre, le premier est de proposer une autre perception pour enrichir les outils de quantification de la précision en fournissant un modèle numérique fondé sur le principe de différence entre deux courbes paramétrique. Robuste, il est invariant à la translation et la rotation 2D ainsi qu’au facteur d’échelle, et pour lequel la différence de nombre de points échantillonnés est gérable. Le second but est de présenter un outil qui permet de détecter les zones d’erreur où l’utilisateur trouve une difficulté à les reproduire, et par conséquent déduire les formes à éviter dans un geste de contrôle.
Key Words	Précision du geste, Métrique des Erreurs et Différence entre courbes paramétriques.

Abstract	Le raisonnement par classification permet entre autre de se positionner à une situation connue pour en appréhender une nouvelle, ou bien de reconnaître un objet en examinant ses caractéristiques afin de retrouver la classe à laquelle il se rattache. Ce mode de raisonnement est couramment utilisé dans les systèmes à héritage où les concepts sont décrits comme des collections de propriétés et organisé en hiérarchie. Cette hiérarchie forme le réseau sémantique d’une base de connaissances d'un système à raisonnement par classification. Nos travaux dans ce papier se situent dans le cadre des systèmes d'aide à la décision par le raisonnement pour classification visant maîtriser cette approche et de cerner les problèmes auxquels on se confronte, et ceci à travers une application dans le domaine de la pédologie. Notre système est conçu pour assister le pédologue dans son travail et en particulier dans la classification des sols.

Abstract	La collecte et l’intégration de données depuis plusieurs sources est une opération de préparation de données pratiquement présente dans tout projet du data mining. Avec l’avènement du Web et des bibliothèques numériques, le texte en langue naturelle est devenu une source importante d’informations pour le data mining. L’utilisation du texte comme source de données pâtit d’un grand obstacle à l’intégration et à la précision de données. Cet obstacle est l’ambiguïté des sens des mots y compris l’ambiguïté des toponymes (les noms des lieux) : un seul toponyme peut avoir plusieurs sens c.-à-d. peut se référer à plusieurs lieux dans la Terre. La Désambiguïsation des Toponyme est la tâche d’associer à un toponyme le lieu à lequel il se réfère. Cet article présente une nouvelle heuristique de désambiguïsation des toponymes dans le texte basée sur la mesure de corrélation entre les chemins hiérarchiques des référents candidats des toponymes du même contexte.

Titer	Une architecture dynamique pour la résolution des problèmes d’optimisation des opérateurs de la téléphonie mobile
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Les opérateurs de la téléphonie mobile sont de plus en plus exigeants vis-à-vis de leurs applications. Ils attendent une grande fiabilité, un nombre sans cesse croissant de services, le respect des contraintes de convivialité, de coût, etc. De ce fait, la taille et la complexité des applications augmentent. Les techniques actuelles ne permettent pas de nous protéger des problèmes de conception. C’est pourquoi nous avons besoin d’une modélisation de haut niveau, qui nous permettra d’analyser l’organisation entre les différents éléments du système et les interactions entre ces éléments. L’intérêt des systèmes multi agents découle des comportements collectifs produits par les interactions de plusieurs entités autonomes et flexibles appelées agents, que ces interactions tournent autour de la coopération, de la concurrence ou de la coexistence entre ces agents. Cependant des techniques viennent de ce domaine, se concentrent plus sur l’expression des relations inter-agents. L’expression de la mobilité du point de vue des systèmes distribués n’est pas décrite. Une propriété une fois acquise, permettra à des processus de choisir eux-mêmes de se déplacer sur les sites d’un réseau afin de travailler localement sur les ressources et de se faire échanger leurs interactions. Raison pour laquelle, nous allons proposer dans ce papier une formalisation qui fait appel à une algèbre de processus, qu'est le p-Calcul, afin de concevoir des systèmes auto adaptives qui peuvent réagir à la forme du problème.

Titer	Intensity Estimation of Unknown Expression Based on a Study of Facial Permanent Features deformations
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	In this work we report on the progress of building a system that enables the intensity estimation of unknown expression based on a study of the degree of facial permanent features deformations from still images. The facial changes can be identified as facial action units which correspond to the movement of muscles. We analyze subtle changes in facial expression by interpreting the movement of the muscle by its corresponding distances computed from characteristic facial points. All changed distances, are compared with corresponding Thresholds, to be mapped to symbolic states that qualitatively encode how much a given distance differs from its corresponding value in the neutral state. The Transferable Belief Model is used to fuse all data which correspond to the whole of changed distances. Expression intensity is quantified as: High, medium or low. Different raisons are done to prove that is better to estimate expression intensity of unknown expression than of known one.

Titer	Unsupervised Classification Based Negative Selection Algorithm
Laboratory	MISC Laboratory of Constantine

Abstract	In the last decade, artificial life has been considered as a promising area for rising challenges to unresolved computational problems. Inspired by natural phenomena, its study focuses on the exploration of complex systems. Neuronal networks, genetic algorithms and more recently artificial immune systems are examples. Artificial Immune Systems (AIS) are one type of intelligent algorithms inspired by the principles and processes of the human immune system. Emulating the discrimination mechanism of the natural system, negative selection algorithm of AIS has been successfully applied on change and anomaly detection. This paper describes initial investigations in applying negative selection algorithm on pixel classification by maintaining a population of detectors that remove undesired patterns. Its purpose is to find several detectors which do not match to self in the population. We make use of an Euclidian space with an Euclidian performance measure on color images. The experimental show promising results. The obtained classifier is effective and feasible.

Abstract	With the development of databases in general and data warehouses in particular, it is now of a great importance to reduce the administration tasks of data warehouses. The materialization of views is one of the most important optimization techniques. The construction of a set of views optimizing the data warehouse is an NP-hard problem. In this paper, we provide an extension of our algorithm Adapted extremal Optimization introduced in [1] without any improvement of its effectiveness. Performance tests have been conducted on the well known TPC-h benchmark in order to evaluate the effectiveness of the algorithm comparing it with other well known methods.

On the other hand, we present a tool to detect error areas (where the user has a difficulty to reproduce the gesture), and thus deduce the forms to avoid in an act of control.

C’est un enjeu important car la cartographie numérique présente des avantages pour les services d’archives, les bibliothèques, les historiens. La carte géographique numérisée nécessite un prétraitement améliorant sa qualité à cause de la présence de plusieurs types de dégradations. Certaines dégradations peuvent être traitées grâce aux algorithmes de prétraitement d’images, d’autres nécessite des connaissances externes.

Titer	Approximate Flexible Queries Using Hausdorff Distance
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Approximate flexible queries have emerged as an effective approach in the process of interrogation of the databases, and more especially for dealing the problem of empty answers. Most work in this domain, however, has so far been limited in its applicability and capacity to treat the problem of empty answers. In this paper, we propose the use of Hausdorff distance as an effective tool for approximate flexible queries in the context of treatment the Empty Answers Problem (EAP). Our approach is based on measuring semantic proximity between flexible queries and using this measure to provide approximate answers to failed queries (queries with empty answers). We develop novel approach for approximate flexible queries by using the Hausdorff distance applied between fuzzy predicates compounded these queries. This, of course, guarantees extremely non empty answers with fast response times.

Abstract	It is a big pleasure for the user to find the result of its skyline query without waiting for its processing; this can be realized by getting a saved version of this query. This paper focuses on the pre-computation of the skylines of all possible non- empty subsets of a given set of dimensions, what we call the skycube. We develop an efficient top-down approach called TOP-SKY for the skycube computation which derives the skyline objects from one of the subspace’s parents adopting some techniques that help to achieve a better performance. In order to evaluate the effectiveness of the approach, TOP-SKY has been compared with the best algorithm in our knowledge Orion and with computing the cuboids of the skycube individually using BNL algorithm.

Titer	A discrete firefly algorithm for geometric image inpainting information
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	Image inpainting is the process that reconstructs the image’s structure by matching each damaged contour with its corresponding one in such a way to obtain an image visually plausible. The search space of candidate solutions increases dramatically as the number of contours increases, which makes the search of the optimal solution by a traditional deterministic method infeasible. A good choice to solve this problem is the use of a meta heuristic, which is in the present paper a discrete version of the Firefly algorithm. So, in the present paper, a Discrete FFA (DFFA) is used to find close contours using their curvatures and values abscise of curve’s end point. The advantage of using curve’s end point is to add spatial information of the location of damaged contour. Experiment results show the efficiency of the DFFA for the geometric image inpainting.

Titer	Materializing distributed Skyline queries
Laboratory	MISC Laboratory of Constantine
Universities	Constantine 2 university and El Oued university
Abstract	The materialization of views has been one of the most successful techniques in optimizing OLAP queries. In this context, many works have been conducted aiming either to study the relationships between the views or to solve the materialized views selection problem. The efficiency of this technique motivates the database community to apply it on other types of queries namely the skyline. However, researchers investigated only the first phase of the materialization by adapting some approaches proposed for OLAP queries namely the skycube. The second phase of the materialization which is the materialized skyline views selection problem has never been studied because of the difficulty of creating a cost model. In fact, the differences between OLAP and skyline queries are the main obstacle for using the cost models proposed for the former in studying the later. More precisely, the methods used to estimate the cost of evaluating an OLAP query are not applicable to a skyline query. Besides, evaluating the query without estimation in each step of the selection process leads to a very high cost. In this paper we propose a genetic method for the materialized skyline views selection problem. In order to reduce the high cost produced by evaluating all over the selection process, we propose a time reduction heuristic called OnceVisited which avoids the computation of the same query from the same views many times.

Abstract	In the context of improving the information retrieval on the web, we propose in this paper an original approach based on geometric queries, whose goal is to reduce the problem of the non-selection of relevant documents, this issue is known as silence problem. This approach is based on the transformation of user query into geometric shapes and exploitation of a set of previously executed queries (with relevant responses) to find the closest to the initial query by using a similarity measure. We will focus on the need to involve domain ontology in the construction of geometric queries. Finally this paper describes the implementation performed and draws the first conclusions on various perspectives of this approach.

Abstract	En Algérie, les différentes études géologiques et sismologiques montrent que 70% du Nord du pays sont soumis à l'activité sismique. Dans cette partie du territoire national sont concentrées au moins 90% des installations socio-économiques et politiques du pays. Cette partie de l’Algérie est traversée par des failles qui font de notre pays un territoire à risque. Des villes entières ont été complètement détruites par le passé. Les dernières années le CRAAG a densifié le réseau national par l’implantation de nouvelles stations couvrant les zones sismiques. Le réseau de surveillance sismique algérien est composé de 35 stations du réseau télémétré et de 45 stations digitales acquises récemment. Il couvre aujourd’hui la plus grande partie de la région Nord du pays notamment la région Nord-est, là où se produit la plus grande activité sismique du pays.
Key Words	Gestion des données sismiques, Région de Constantine, Station de surveillance et Réseau de surveillance.

Abstract	The reasoning by classification, amongst other positioning itself to a known situation makes to understand a new, or to recognize an object by examining its characteristics to find the class to which it relates. This reasoning is commonly used in legacy systems where the concepts are described as collections of properties and organized in hierarchy. This hierarchy forms the semantic network a base of knowledge reasoning by classification system. Our work in This paper are located within the framework of decision support systems by the reasoning for classification to control this approach and identify problems to which it presents, and this through an application in the field of the soil science. Our system is designed to assist the pedologist in its work and in particular in the soils classification.

Abstract	Le data mining est un nouveau domaine qui a apparu à la fin des années quatre-vingt, et il a prouvé son existence en tant que solution viable pour analyser les grandes quantités de données. Le data mining s'est développée à partir de la contribution de plusieurs disciplines, y compris la statistique, les bases de données, l'intelligence artificielle, et autres. Le principal objectif de cet article est de clarifier la relation étroite entre le data mining et la statistique, pour cela nous présentons trois aspects de la relation entre ces deux domaines. Nous discutons aussi la question sur le data mining s’il est une science ou non et la relation de la réponse avec la perspective au sens du terme « data mining ». Cet article est destiné en premier lieu aux chercheurs informaticiens dans le domaine du data mining qui sont novices dans le domaine de la statistique.
Key Words	Data mining, Statistiques et KDD.

Abstract	The spatial requests require the utilization of the specific access methods in order to accelerate their execution. Numerous methods are proposed to these needs: structures in grids, the quaternary tree, and the tree rectangle. Also, to accelerate the time of research of the spatial objects, and for more of efficiency in the spatial request resolution, it is necessary to endow itself/themselves of a spatial index that either optimal. However, this stain requires a qualitative assessment of the different structures of index that depends strongly on choices of the implementation achieved, of real data games, and of the tested operations. Our objective in this paper, is to propose a technique of index optimization for objects represented on a map mono-lies down either on a map multi-lies down, and we will restrict to the operation of base solely: (the operation of pointed). This technique is based on efficient approach in two phases, and lean especially on the suppleness of the quadtrees-linear that is bound to the numeric aspect of the representation and research. These two phases are filtering that generates objects candidates for the resolution of a request and the sophistication that operates directly on the descended objects of the first phase to form the result.

Abstract	La très grande complexité et variété des données, l’entreposage très grand et énorme des données, l’augmentation de la puissance de calculs des ordinateurs et l'accès aux réseaux de très grande taille nous donnent une complexité et un coût élevés des requêtes de fouille de données (data mining) surtout dans un environnement parallèle ou distribué. D’où, la possibilité que le problème d’interopérabilité se poser. L’optimisation de ces requêtes est l’intérêt actuel de la communauté des dépôts de données et des bases de données. De nouveaux algorithmes ont été proposés mais très peu de travaux ont utilisé l'approche par matérialisation. Dans ce papier, nous allons abordé une approche d’optimisation basée sur la matérialisation et plus précisément sur la sélection des vues matérialisées en utilisant principalement une classification non supervisé pour classer les requêtes similaires en terme de syntaxe.
Key Words	Base de données multidimensionnelle, Dépôts de données, Matérialisation des vues, Optimisation des requêtes et Interopérabilité.

Abstract	Face à la croissance de la demande des services de plus en plus riches et personnalisés, le défit aujourd’hui est de proposer des applications pervasives de la meilleure qualité de service possible, permettant de s’adapter aux souhaits de l’utilisateur et à son environnement. D’autre part, les systèmes multi-agents (SMA) connaissent actuellement un certain engouement, en raison de leur capacité à aborder les systèmes complexes. Nous nous intéressons dans ce papier à la présentation d’un survol sur le domaine des systèmes pervasifs sensibles au contexte ainsi qu’une synthèse des travaux usuels de ce domaine tout en essayant de couvrir à la fois les concepts de l’informatique pervasive, la sensibilité au contexte dans ces systèmes, la gestion qualité de service (Qds) et les systèmes multi-agents.
Key Words	Applications pervasives, Sensibilité au contexte, Gestion de la qualité de service, Adaptation dynamique, Architecture logicielle et Système multi agents.
