Dynamicity is an important requirement for critical software adaptation where a stop can be dangerous (e.g. for humans or environment) or costly (e.g. power plants or production lines). Adaptation at run-time is also required in context-aware applications where execution conditions often change. In this paper, we introduce MaD-cAr, an abstract model of(More)
Adaptive Object Models are a sophisticated way of building object-oriented systems that let non-programmers customize the behavior of the system and that are most useful for businesses that are rapidly changing. Although systems based on an Adaptive Object Model are often much smaller than competitors, they can be difficult to build and to learn. We believe(More)
HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt età la diffusion(More)
Dans cet article, nous introduisons MADCAR, un modèle de moteurs dédiés à la construction et à la reconfiguration dynamique et automatique d'ap-plications à base de composants. Dans MADCAR, la description d'une application regroupe la définition des configurations valides et les règles de transfert de l'état de l'application lors des adaptations. Cette(More)
In object-oriented systems, runtime memory is composed of an object graph in which objects refer to other objects. This graph of objects evolves while the system is running. Graph exporting and swapping are two important object graph operations. Exporting refers to copying the graph to some other memory so that it can be loaded by another system. Swapping(More)
In this paper, we introduce MaDcAr, a model of engines for dynamic and automatic (re)assembling of component-based software. In MaDcAr, an application description consists of the definition of some valid configurations and the state transfer rules to apply during adaptations. This description is uncoupled from any implementation and can therefore be reused(More)
In this paper, we claim that both prototype-based visual programming and traditional Smalltalk class-based programming are required for developing applications with a GUI. We introduce Easy Morphic GUI (EMG), a framework that connects Morphic and EToys visual manipulation and scripting facilities with the usual Smalltalk development environment tools. The(More)
— Maintaining the network connectivity in mobile Multi-Robot Systems (MRSs) is a key issue in many robotic applications. In our view, the solution to this problem consists of two main steps: (i) making robots aware of the network connectivity; and (ii), making use of this knowledge to plan robots tasks without compromising connectivity. In this paper, we(More)
