The modelling of processes that occur in landscapes is often confronted to issues related to the representation of space and the difficulty of properly handling time and multiple scales. In order to investigate these issues, a flexible modelling environment is required. We propose to develop such a tool based on a Domain Specific Language (DSL) that capitalises on the service-oriented architecture...
Grammar metrics have been introduced to measure the quality and the complexity of the formal grammars. The aim of this paper is to explore the meaning of these notions and to experiment, on several grammars of domain specific languages and of general purpose languages, existing grammar metrics together with new metrics based on grammar LR automaton and on the produced language. We discuss the results...
This paper presents a Java framework based on separation of concerns and code generation concepts that facilitates development of concurrency and I/O in servers. In this approach, the application is modeled by a graph whose vertices correspond to units of treatment connected by channels. It allows to build all kind of servers: multithreaded, single-process event-driven, staged event driven architecture,...
