Guidelines for a Dynamic Ontology - Integrating Tools of Evolution and Versioning in Ontology

Ontologies are built on systems that conceptually evolve over time. In addition, techniques and languages for building ontologies evolve too. This has led to numerous studies in the field of ontology versioning and ontology evolution. This paper presents a new way to manage the lifecycle of an ontology incorporating both versioning tools and evolution process. This solution, called VersionGraph, is integrated in the source ontology since its creation in order to make it possible to evolve and to be versioned. Change management is strongly related to the model in which the ontology is represented. Therefore, we focus on the OWL language in order to take into account the impact of the changes on the logical consistency of the ontology like specified in OWL DL

Simulation and Visualization of Thermal Metaphor in a Virtual Environment for Thermal Building Assessment

La référence est présente sur HAL mais est incomplète (il manque les co-auteurs et le fichier pdf).The current application of the design process through energy efficiency in virtual reality (VR) systems is limited mostly to building performance predictions, as the issue of the data formats and the workflow used for 3D modeling, thermal calculation and VR visualization. The importance of energy efficiency and integration of advances in building design and VR technology have lead this research to focus on thermal simulation results visualized in a virtual environment to optimize building design, particularly concerning heritage buildings. The emphasis is on the representation of thermal data of a room simulated in a virtual environment (VE) in order to improve the ways in which thermal analysis data are presented to the building stakeholder, with the aim of increasing accuracy and efficiency. The approach is to present more immersive thermal simulation and to project the calculation results in projective displays particularly in Immersion room (CAVE-like). The main idea concerning the experiment is to provide an instrument of visualization and interaction concerning the thermal conditions in a virtual building. Thus the user can immerge, interact, and perceive the impact of the modifications generated by the system, regarding the thermal simulation results. The research has demonstrated it is possible to improve the representation and interpretation of building performance data, particularly for thermal results using visualization techniques.Direktorat Riset dan Pengabdian Masyarakat (DRPM) Universitas Indonesia Research Grant No. 2191/H2.R12/HKP.05.00/201

Maisons et agglomérations à l'âge du bronze en Syrie du Sud

A paraître dans : HAURAN V - Déterminismes géographiques et communautés humaines en Syrie du Sud du néolithique à l'antiquité tardive. Recherches récentesSous la direction deMichel al-Maqdissi, Frank Braemer, Jean-Marie Dentzer BAH ; IFPO BeyrouthEn Syrie du Sud la remarquable conservation des vestiges et leur bonne lisibilité en surface ont permis de localiser et de relever des agglomérations, parfois sur d'importantes superficies. Les fouilles et prospections ont permis le relevé d'une cinquantaine de plans de sites datés entre le 4e et le 2e millénaire. Cette région est en effet un véritable conservatoire, sans doute unique au monde, de structures architecturales protohistoriques.Cet article se limite à une description générale des formes d'habitat domestique et de l'organisation des agglomérations, et n'aborde donc pas les questions des aménagements des paysages autour des sites (principalement les ouvrages hydrauliques), des édifices monumentaux et des techniques de fortification. Ces régions étaient occupées principalement par des populations pastorales mobiles qui ont bien souvent construit des agglomérations fixes qui représentent les points d'appui logistique (réserves, assemblées, etc..) de leur circuit de déplacement cyclique

WiseNET: smart camera network combined with ontological reasoning for smart building management

International audienceVisual sensor networks (VSN) have become a part of our daily life [1] [2]. Based on our experience we have identified two main problems on VSN. Firstly, the problem of selecting relevant information from the huge amount of data given by the network. Secondly, the problem of integrating the information coming from the different nodes of the network, i.e., linking the different informations together in order to take a decision. These problems can be overcome by including smart cameras in charge of extracting the significant information from the scene and by adding contextual semantic information, i.e., semantic information of what the camera observes, building information and events that may occurred. Semantic information coming from different nodes can be easily integrated in an ontology. Our approach differs from standard computer vision, which deals with algorithm improvement [3] [4] and signal processing problems [5], by dealing with a meaning problem in computer vision, where we try to improve and understand what the camera " sees " by adding contextual semantic information. We developed an innovative distributed system that combines smart cameras with semantic web technology. The proposed system is context sensitive and provides knowledge and logic rules in order to optimize the usage of a smart camera network. The main application of our system is smart building management, where we specifically focus on improving the services of the building users. The WiseNET (Wise Network) system consists of a smart camera network connected to an ontological model. The communication between the smart camera network and the ontological model is bidirectional, i.e., the cameras can send information either when the model asks for it or whenever new data becomes available. The ontological model is a semantical one that allow us to express information in our system and to take decisions according to combinations of the different information [6]. The semantical model is articulated in three sections: sensor, environment and application. All the sections are bilaterally connected between themselves by properties and relations. The sensor section consists of a semantic web vocabulary concerning the smart camera, the image processing algorithms and their results [7]. The sensor section is in charge of giving a semantic meaning to what the smart cameras observes, a problem known as semantic gap [8]. The environment section is composed by a semantic web vocabulary regarding the building information model (BIM) [9]. Finally, the application section comprises a set of rules defining some events that may be important for security applications and the different decisions to take according to the occurrence of these events [10]

TIME: A Case Tool for developing Web-based Cooperative IS

Distributed web oriented processing environments have created the need for information sharing and transparent data access across heterogeneous information systems. This need stems from the proliferation of network based technologies that provide universal access to a growing number of information sources. Recently, new information system architectures including federated databases, cooperative information systems, and interoperable systems have been advocated in database research for the interoperation of multiple autonomous heterogeneous information systems over distributed networks

Paola Sconzo, Pottery and Potmarks at an Early Urban Settlement of the Middle Euphrates River Valley, Syria. Final Reports of the Syrian-German Excavations at Tell el ‘Abd II

En 1971 et 1972, Adnan Bounni dirigea deux missions de fouille de sauvetage à Tell el-‘Abd dans la zone du futur barrage de Tabqa (moyen Euphrate syrien). Vingt ans plus tard, profitant d'une baisse temporaire des eaux du lac, Uwe Finkbeiner réalisa trois nouvelles campagnes entre 1992 et 1994. La céramique découverte à cette occasion a été étudiée par P. Sconzo dans le cadre d’une thèse soutenue à l’Université de Tübingen en 2010. C’est ce travail qui est publié dans la collection des AVO co..
