Texto completo da fonteModel-based systems engineers and architects, particularly those moving from software to systems engineering, claim that SysML-like modelling notations, symbolic two-dimensional diagrams made of boxes and lines, are domain-independent and, thus, very convenient to support the cross-functional definition of a system architecture. However, the abstract diagramming syntax of Model-Based Systems Architecting (MBSA) notations makes their adoption difficult, especially by notational nonexperts, and using iconic graphics is one way of improvement. Few studies attempted to replace 2D diagrams with immersive 3D visuals without objective evidence. We assume it is due to limited development efforts and a need for more quality criteria for comparing 2D diagrams with 3D visuals. This thesis will argue that human-centric interactive 3D visuals should replace MBSA diagrams where appropriate to facilitate communication and participation in multidisciplinary co-design activities from mission to architecture definition. A combination of empirical validation methods shows that the proposed 3D immersive MBSA interface increases user satisfaction, provides better visual notations, and reduces cognitive load for single- and multi-user MBSA activities involving experts and non-experts. Such promising results of this exploratory research pave the way for more specific studies to cumulate scientific evidence

Texto completo da fonteSystems-of-Systems (SoS) is becoming one of the major paradigm forengineering next generation solutions such as smart cities, smart buildings, health-care, emergencyresponse and defense. Therefore, there is a growing interest in SoS, their architecture and speciallytheir security. However, SoS differentiating characteristics, such as emergent behavior andmanagerial and operational independence of its constituents, may introduce specific issues thatmake their security modeling, simulation and analysis a critical challenge. In this thesis we investigatehow Software Engineering approaches can be extended to model and analyze secure SoS solutionsfor discovering high impact attacks (cascading attacks) at the architecture stage. In order to achieveour objective, we propose a Model Driven Engineering method, Systems-of-Systems Security(SoSSec), that comprises: (1) a modeling description language (SoSSecML) for secure SoS modelingand an extension of Multi-Agent Systems (MAS) for secure SoS architecture analysis, (2) thecorresponding tools: a graphical editor, a code generator, an extension of the Java AgentDevelopment (JADE) MAS simulation framework, a custom logging tool, (3) an utilization process toguide the use of the SoSSec method. To illustrate our approach we conducted a case study on a reallifesmart building SoS, the Adelaide University Health and Medical School (AHMS)
Pham, Van Cam. "Model-Based Software Engineering : Methodologies for Model-Code Synchronization in Reactive System Development". Thesis, Université Paris-Saclay (ComUE), 2018. http://www.theses.fr/2018SACLS611/document.
Texto completo da fonteModel-Based Software Engineering (MBSE) has been proposed as a promising software development methodology to overcome limitations of traditional programming-based methodology in dealing with the complexity of embedded systems. MBSE promotes the use of modeling languages for describing systems in an abstract way and provides means for automatically generating different development artifacts, e.g. code and documentation, from models. The development of a complex system often involves multiple stakeholders who use different tools to modify the development artifacts, model and code in particular in this thesis. Artifact modifications must be kept consistent: a synchronization process needs to propagate modifications made in one artifact to the other artifacts. In this study, the problem of synchronizing Unified Modeling Language (UML)-based architecture models, specified by UML composite structure (UML-CS) and UML state machine (UML-SM) elements, and object-oriented code is presented. UML-CSs are used for describing the component-based software architecture and UML-SMs for discrete event-driven behaviors of reactive systems. The first challenge is to enable a collaboration between software architects and programmers producing model and code by using different tools. This raises the synchronization problem of concurrent artifact modifications. In fact, there is a perception gap between diagram-based languages (modeling languages) and text-based languages (programming languages). On the one hand, programmers often prefer to use the more familiar combination of a programming language and an Integrated Development Environment. On the other hand, software architects, working at higher levels of abstraction, tend to favor the use of models, and therefore prefer diagram-based languages for describing the architecture of the system. The second challenge is that there is a significant abstraction gap between the model elements and the code elements: UML-CS andUML-SM elements are at higher level of abstraction than code elements. The gap makes current synchronization approaches hard to be applied since there is no easy way to reflect modifications in code back to model. This thesis proposes an automated synchronization approach that is composed of two main correlated contributions. To address the first challenge, a generic model-code synchronization methodological pattern is proposed. It consists of definitions of necessary functionalities and multiple processes that synchronize model and code based on several defined scenarios where the developers use different tools to modify model and code. This contribution is independent of UML-CSs and UML-SMs. The second contribution deals with the second challenge and is based on the results from the first contribution. In the second contribution, a bidirectional mapping is presented for reducing the abstraction gap between model and code. The mapping is a set of correspondences between model elements and code elements. It is used as main input of the generic model-code synchronization methodological pattern. More importantly, the usage of the mapping provides the functionalities defined in the first contribution and eases the synchronization of UML-CS and UML-SM elements and code. The approach is evaluated by means of multiple simulations and a case study

"Vers une approche commune pour le logiciel et le matériel de spécification et d’implémentation des systèmes embarqués temps-réels distribués, basée sur les intergiciels et les composants orientés objet : Application aux modèles de composants Software Communications Architecture (SCA) et Lightweight Corba Component Model (LwCCM) pour les systèmes de radio logicielle".

Texto completo da fonteThis thesis deals with the hardware application of the software concepts of middleware and software architecture based on components, containers and connectors within Field-Programmable Gate Arrays (FPGAs). The target application domain is Software Defined Radio (SDR) compliant with the Software Communications Architecture (SCA). With the SCA, software radio applications are broken into functional waveform components to be deployed on heterogeneous and distributed hardware/software radio platforms. These components provide and require abstract software interfaces described using operation signatures in the Unified Modeling Language (UML) and/or the Interface Definition Language (IDL) of the Common Object Request Broker Architecture (Corba) middleware, both standardized by an international software industry consortium called Object Management Group (OMG). The portability and reusability needs of these business components require that their abstract interfaces defined at a system level are independent of a software or hardware implementation and can be indifferently translated into a software programming language like C/C++, a system language like SystemC at transaction level (Transaction Level Modeling - TLM), or a hardware description language like VHDL or SystemC at Register Transfer Level (RTL). The interoperability need of SDR components requires transparent communications regardless of their hardware/software implementation and their distribution. These first needs were addressed by formalizing mapping rules between abstract components in OMG IDL3 or UML2, signalbased hardware components described in VHDL or SystemC RTL, and system components in SystemC TLM. The second requirement was addressed by prototyping a hardware middleware using transparently memory mapping and two message protocols: Corba General Inter-Object Request Broker Protocol (GIOP) and SCA Modem Hardware Abstraction Layer (MHAL)

Texto completo da fonteThe integration of mechatronic systems generates many multi-physical disturbances (thermal, electromagnetic and dynamic) making their choice of architecture complex. Indeed, the increasing introduction of electronic and electrical (E/E) components in most of the current systems, increases the risk of occurrence of many electromagnetic interferences (EMI) that can strongly degrade their behavior. While these electromagnetic compatibility (EMC) problems are usually addressed in the detailed design phase, where the possibilities of compromise are limited to a few positioning adjustments or costly protection solutions, one solution is to propose a collaborative framework for the evaluation, from the early design phases, of physical design architectures taking into account these electromagnetic (EM) constraints. Actually, it is important at this stage that all the multidisciplinary actors involved can define, modify/update, add their knowledge and constraints and exchange their data while continuing to work in their usual digital environment. In addition, these system engineering activities must be supported with "Model-Based System Engineering" (MBSE) approaches, to support the digital continuity, consistency and traceability of the models and data required for this evaluation process.To meet this need, this thesis is based on the MBSE SAMOS (Spatial Architecture based on Multi-physics and Organization of Systems) collaborative approach to support, from the preliminary design phase, the evaluation of the 3D concept architecture under electromagnetic constraints. In this context, we have initially developed a SysML extension called EMILE (ElectroMagnetic Interactions Layout Extension) to formalize and model, as early as possible, the EM constraints in the system model.This extension notably includes the definition of EM requirements, the description of electromagnetic coupling modes and the specification of simulation configurations allowing the further verification and validation of the requirements, thanks to the development of a Human-Machine Interface. Our research work then focused on an evaluation methodology combining a topological approach with EM modeling, in order to support the process of qualitative and quantitative evaluation of electromagnetic interference (EMI). Indeed, for a given type of EMI, the topological analysis of the system architecture allows to qualitatively identify the existence of the victim components and their associated potential aggressors. Once these potential EMIs have been identified, a quantitative evaluation can then be performed, for example based on the physical equations and laws of the identified coupling, and on the electromagnetic and geometric requirements predefined with the EMILE extension. As a result, this approach ensures the relevant choice of a 3D physical architecture of the concept under EM constraints. The proposed approaches have been illustrated on a case study of an electric vehicle power train, based on various software implementation scenarios (SysML, Modelica, Matlab, FreeCAD) within the Sketcher 3D EM tool
Alby, Emmanuel. "Elaboration d'une méthodologie de relevé d'objets architecturaux : contribution basée sur la combinaison de techniques d'acquisition". Nancy 1, 2006. https://tel.archives-ouvertes.fr/tel-00132784.
Texto completo da fonteThe external survey of an architectural work is a way to create a representation of the building in its conservation condition. Two techniques of remote acquisition differ by their effectiveness and the quality of the produced data: photogrammetry and laser scanning. These two techniques depend on optical principles: what cannot be seen cannot be measured. The combination of these techniques can improve the data quality, but unmeasured zones always remain, therefore cannot be represented. In order to solve this problem, we put forward the hypothesis that using architectural knowledge may allow to rebuild these zones during the modeling process. This study suggests a modeling process based on the combination of these two techniques and on the integration of the available architectural knowledge, from paper documentation or from the built works construction rules. An architectural work being complex and the data numerous, a division of the modeling process in several distinct stages appears necessary. We suggest dividing modeling process according to different figuration of level of details frequently used to represent architecture, and define a process using information in a progressive way. Thus our approach consists in integrating dimensional data into architectural documentation, in order to develop a modeling process providing a model as complete as possible

Texto completo da fonteThe research work described in this thesis pertains to software applications that generate significant volumes of data. The produced images convey strong domain-specific semantics. Their graphic nature does not lend itself easily to making use of segmentation tools (diversity among images of the domain, among techniques used to generate images, etc. ). Today, image annotations are carried out (done) by domain experts. The costs brought about by these annotations result into many collections not being annotated and thus not being much or at all exploitable outside the project for which they have been produced. In order to reduce annotation costs, we strive to lower the level of expertise needed for making image annotations (most often by a domain technician). As there is no question of accepting a decrease in annotation quality, it is absolutely essential to guarantee that image annotations conform to the domain. In order to implement our solution, we rely on : the domain knowledge as it is available (models, ontologies, standards, etc. );the knowledge of the project within whose scope the image collection has been produced (techniques, experience, etc. ); a generic model of an image database developed as part of the IkoSem project. The method that we propose consists of consolidating the knowledge in a double architecture of models and ontologies. The coupling allows to help a person making image annotations by ensuring that these annotations conform to the domain knowledge

Texto completo da fonteThe present thesis explores the use of a semantic approach for indexing resources that are shared among a community of users who are scattered in a peer-to-peer network. The thesis contributes to the studies of Semantic Indexing approaches that can be used both with resources owned within personal memories, and with resources that are shared in a distributed network. Because the system is generic, the exact nature of the distributed community can be left undefined but our narrower focus is on applications in the e-learning domain. To address the problem that resources have different types, an indexing system is proposed that is based on the user point of view and is performed manually. Indeed, because indices refer to the subjective information that is not necessarily contained in the resources or that are hard to extract from documents that are not textual, the indexing of such type of resources can only be done in an interactive way. We show that a unique approach can be taken that allows one to store documents in personal or collective memories. The approach requires suitable browsing interfaces for accessing ontologies that satisfy and facilitate indexing. We therefore also define an Indexing Patterns system for managing ontologies that can be utilized for creating indices. The method is intended to facilitate the browsing of ontologies by showing only that part of the ontology that is useful for indexing and can be employed by users of various operating systems. A related problem that we address concerns the difference between the publication context and the retrieval context. The solution poroposed in this thesis foresees different retrieval situations and queries during the time a resource is published and builds the index based on those assumptions. The intended practical application encapsulates in a transparent manner the functionalities that the user requires for managing the resources. The development of a prototype is guided by Architectural and Implementation descriptions of the indexing system, both of which are described in the thesis. Although the solution we offer is generic and can be used by different user communities, the approach benefits Domain Specific Communities in particular, by assisting specilized loose communities that are structured as peer to peer networks and that allow publishing and searching of documents

Texto completo da fonteLes environnements de simulation énergétique existants ont été conçus pour des bâtiments classiques pour lesquels les consommations sont beaucoup plus importantes que celles fixées pour 2012, il faut donc voir si les modèles mais aussi les méthodes de simulations utilisés correspondent toujours aux spécificités de ces nouveaux bâtiments. L'objectif de ce travail est de montrer l'intérêt d'utiliser un environnement de simulation basé sur les systèmes d'équations pour étudier le comportement énergétique des bâtiments basse consommation.
Pour cela, plusieurs modèles ont été implémentés dans l'environnement SIMSPARK. Il s'agit d'un modèle de matériau à changement de phase, d'un modèle de prise en compte du rayonnement de courtes longueurs d'onde par calcul de la tache solaire et d'un modèle d'échangeur air-sol. Ils ont été intégrés dans un modèle global de bâtiment basse consommation ce qui a permis de montrer les avantages de l'environnement de simulation utilisé. Le fait qu'il soit orienté objet permet de valider indépendamment les nouveaux modèles puis de les intégrer facilement à un modèle de niveau hiérarchique supérieur. Le fait qu'il soit basé sur les systèmes d'équations a permis grâce à la non orientation a priori du modèle d'inverser le sens de résolution de plusieurs problèmes dans une simulation dynamique. Enfin, la robustesse des méthodes de résolution utilisées a été éprouvée.
