Distributed Reactive Machines

One considers systems made of synchronizers to which distributed reactive machines are connected. The corresponding model is described with its implementation in Java, using SugarCubes and the RMI mechanism

The Junior Reactive Kernel

We define Junior as a Java framework kernel for reactive programming with broadcast events. We give Junior a formal semantics based on rewriting rule. We also describe three implementations of Junior. The first one, called REWRITE, is the direct implementation of the semantics rules. The second one is called REPLACE; it is more efficient than REWRITE as it reuses Java objects instead of always creating new ones. The third implementat- ion, called TURBO, optimises the number of syntax tree traversals and is adapted to situations where there are a large number of events. Finally, we discuss the extension of Junior to distributed contexts and compare it with the SugarCubes Reactive Java framework

Development and Specification of Virtual Environments

This thesis concerns the issues involved in the development of virtual environments (VEs). VEs are more than virtual reality. We identify four main characteristics of them: graphical interaction, multimodality, interface agents, and multi-user. These characteristics are illustrated with an overview of different classes of VE-like applications, and a number of state-of-the-art VEs. To further define the topic of research, we propose a general framework for VE systems development, in which we identify five major classes of development tools: methodology, guidelines, design specification, analysis, and development environments. Of each, we give an overview of existing best practices
