Distributed systems now encounter extreme heterogeneity in the form of diverse devices, network types etc., and also need to dynamically adapt to changing environmental conditions. Selfadaptive middleware is ideally situated to address these challenges. However, developing such software is a complex task. In this paper, we present the Gridkit self* approach to the engineering of reflective midd...

We present a real-time video and image acquisition system, which has important characteristics such as modularity, configurability, versatility, and low cost. This system was developed on the Altera DE2 Board ® using Verilog HDL ® (Hardware Description Language), VHDL ® (VHSIC Hardware Description Language) and Block Diagram as coding languages. The proposed system architecture was applied for ...

State-of-the-art software repositories support optimistic versioning and hence the concurrent editing of one artifact by multiple developers is possible. The drawback of this method is the time-consuming, manual merge process when conflicting changes occur. This is a bigger problem when the artifacts are models. Although similar kinds of conflicts frequently reoccur, current systems hardly prov...

In the past decade, difficulties encountered in reproducing the results of a cancer study at Duke University resulted in a scandal and an investigation which concluded that tools used for data management, analysis, and modeling were inappropriate for the documentation of the study, let alone the reproduction of the results. New protocols were developed which require that data analysis and model...

During the last decades, the frequency of business changes and the time in which these changes have to be incorporated have increased and are still increasing. In this context, the standardization of major application data and of the communication data between applications becomes an important IT issue. However, since people from the business do not speak in a common language, it is more than a...

Specialized software in structural analysis and design are now commercially available and may be adopted in schools to teach students on the use of state-of-the-art software. However, learning to use the software should not be the main objective when these software are integrated in the classroom. Methods on how these software be used to generate “new knowledge” and deepen the understanding on ...

This paper reports on an ongoing research project aimed at designing and deploying a CORBA Commodity Grid (CoG) Kit. The overall goal of this project is to explore how commodity distributed computing technologies and state-of-the-art software engineering practices can be used for the development of advanced Grid applications. As part of this activity, we are investigating how CORBA can be integ...

This paper presents ProCoSA, an environment developed at ONERA for implementing advanced mission management in autonomous vehicles. The rst part describes the motivations and the main features of Pro-CoSA. The second part presents an example of application on the AUV REDERMOR at DCE/GESMA. The name ProCoSA is an acronym for the French title Programmation et Conduite de Systtmes Autonomes whose ...

Advances in computer science have enabled the development of more and more complex systems. One of the most powerful tools to manage these systems is coordination models and languages. However, a serious limitation of these models, with regard to their usability, is that they do not provide support to manage the coordination constraints from the early stages in the software life cycle. Indeed, ...
