Modeling is core software engineering practice. Conceptual models are constructed to establish an abstract understanding of the domain among stakeholders. These are then refined into computational models that aim to realize a conceptual specification. The refinement process yields sets of models that are initially incomplete and inconsistent by nature. The aim of the engineering process is to n...

We present the case for a preliminary organizational model of participation. We review a simulation of the Battle of Medenine with respect to its ability to approximate the historic record. We find that individuals in the actual battle performed with greater variance than the simulation predicted, suggesting that individual differences are important. Using a light-weight simulation, we implemen...

this paper demonstrates a preliminary investigation of geometry, function and its relation to dfx principles, namely dfm (design for manufacturing). this is the starting point for research on the development of an expert system that assesses design goals along dfx principles in a feature-based cad environment. there is a need for a deeper level of understanding of the relationship between geome...
