	abstract = {In system-level design, descriptive system models seem to be insufficient in order to perform a system verification which fulfils various stakeholders requirements. This fact is accentuated by the increasing complexity of system engineering projects and, as a consequence, the difficulties to deal with both their coordination and traceability. Even if SysML (System Modeling Language) is considered as a flexible and standard tool for system engineering, using only descriptive models are insufficient for system behavior verifications. To deal with this concern, simulation environments (i.e. MATLAB/Simulink) allow verifying if the system preliminary design satisfies requirements or not. As a consequence, various research works have been centered on combining the potential of both SysML modeling and simulation tools. This paper proposes an integration approach based on metamodeling and model transformations to generate Simulink models from SysML diagrams. This approach is handled by models and modern techniques of MDE (ModelDriven Engineering).},

	abstract = {Advances in wireless communications and mobility have increased the use of smart mobile applications. As a result of the remarkable increase of mobile devices and the pervasive wireless networks, a large number of mobile users are requiring personalization services customized to their context. The mobile cloud-computing paradigm from a context-aware perspective aims to find effective ways to make cloud services aware of the context of their customers and applications. Another major challenge for context-aware cloud services is to exploit the benefits of cloud computing to manage transaction processing throughout the life cycle of a service. In this paper, we focused on the need of loosely coupled context-supporting components that work with a transaction-aware service infrastructure to adapt services to the context of the user and his mobile device. We propose a cloud-based middleware for transactional service adaptation (CM4TSA) by adding the {\textquoteleft}{\textquoteleft}Adaptation as a Service{{\textquoteright}{\textquoteright}} layer into basic cloud architecture, to perform the correct execution of transactional service according to the user context.},

DSM approach for Context aware service oriented systems (SOS) raises many challenges. Particularly, the challenge of engineering such systems, which consists of the definition of modeling approaches, processes, techniques and tools to facilitate construction of these systems. In this paper, we propose a DSM approach for adaptable service oriented systems named CADSSO (Context Aware, Domain Specific and Service Oriented) modeling approach. Our modeling approach is based on five models: domain specific services model (conforms to a domain specific services meta-model) which is a representation of the domain specific services; service variability model (conforms to our service variability meta-model), it formulates services forms of adaptation; domain specific context model (conforms to our context meta-model), symbolize the services context of use; adaptation rules model, which is the joint between service variability model and context model; and domain specific business rules model, used to model domain specific business.},

However, process-centered software engineering environments (PSEE) have traditionally been designed to exploit integration facilities in other tools, while offering themselves little to no such facilities. This is in line with the vision of the PSEE as the central orchestrator of project support tools. We argue that this view has hindered the widespread adoption of process-based collaboration support tools by incurring too much adoption and switching costs. We propose a new process-based collaboration support architecture, backed by a process metamodel, that can easily be integrated with existing tools. The proposed architecture revolves around the central concepts of {\textquoteright}deep links{\textquoteright} and {\textquoteright}hooks{\textquoteright}. Our approach is validated by analyzing a collection of open-source projects, and integration utilities based on the implemented process model server have been deve},

In previous work, we have defined a view-based UML profile called VUML.

We specify the semantics of our composition operator by means of graph transformations. Furthermore, we present a composition scheme interpreted by a two-steps composition process based on two strategies of correspondence and merging.

	abstract = {The challenge in the development of complex systems is to cope with the dynamic nature of the user{\textquoteright}s profile, especially when such systems are exposed to the large public through the Internet. In Service oriented computing (SOC), a service may interact with several types of service clients. The central problem is, therefore, how to model the multidimensional aspect of service clients{\textquoteright} needs and requirements. To tackle this problem, we propose in this paper the concept of the multiview service as a first class modeling entity that permits the representation of the needs and requirements of end-users by separating their concerns. Such adaptable services must carefully be analyzed and designed. However, current works on service oriented analysis and design (SOAD) largely focus on defining processes to develop business processes and services without considering user-aware variability. In the present paper we present an MDA framework for a muliview SOAD process for the development of highly adaptable services. We specify transformations as a collection of rules implemented in ATL. The proposal is illustrated by a simple example.},

	abstract = {Component based software (CBS) intends to meet the need of reusability and productivity. Web service technology leads to systems interoperability. This work addresses the development of CBS using web services technology. Undeniably, web service may interact with several types of service clients. The central problem is, therefore, how to handle the multidimensional aspect of service clients{\textquoteright} needs and requirements. To tackle this problem, we propose the concept of multiview component as a first class modelling entity that allows the capture of the various needs of service clients by separating their functional concerns. In this paper, we propose a model driven approach for the development of user-aware web services on the basis of the multiview component concept. So, we describe how multiview component based PIM are transformed into two PSMs for the purpose of the automatic generation of both the user-aware web services description and implementation. We specify transformations as a collection of transformation rules implemented using ATL as a model transformation language.},

	abstract = {Modern enterprises need to respond effectively and pertinently to users need in a competitive markets. In order to cope with the dynamic nature of user profiles, we propose, in this paper, a Multi-Functional Service oriented system development. While the concept of a service is not new on itself, the multifunctional one provides a convenient new concept which addresses separate properties that cope to different user business domain respecting information pertinence and access right definition. So we focus on a user-driven adaptability of services components. Thus, we present multi-functional service concept; we give a process to identify services common and specific interest according to different user through use cases. We continue our process so to design and deploy such services in the context of the model driven architecture.},
