Computer simulation is an important factor intoday’s disaster prevention procedures. Simulation codes assessthe evolution and impact of various physical phenomena indomains such as nuclear and environmental sciences, andultimately help saving lives. However, new and more computationallydemanding models, and new regulations for personneltraining have(More)
We propose an aspect-oriented approach for the development of simulation software aiming at increasing the flexibility, the rapidity of development, and maintainability of simulation software. The horizontal decomposition method is used to separate the core functionality of the simulation application from simulation-specific cross-cutting concerns like(More)
In this work we advance the understanding of software eco-systems research by examining the structure and evolution of the R statistical computing open-source ecosystem. Our research attempts to shed light on the following intriguing question: what makes software ecosystems successful? The approach we follow is to perform a quantitative analysis of the R(More)
Software architecture entails the making of architectural decisions based on a set of both functional and quality requirements, as well as trade-offs between them, which have to be considered to achieve design goals. Access to accumulated and documented architectural knowledge facilitates this process. In this paper, we present a set of tools that support(More)
