Syntactic modeling and simulation
Article Abstract:
Formal languages are powerful modeling tools in their own right. Applications to biological processes such as growth and behavior emphasize the ability of syntactic models to capture organization clearly, concisely and accurately. This ability can be exploited by designing generic systems ("embodiments") that simulate whole families of processes. Within an embodiment, specific models are defined by formal languages whose semantics relate to the real-world systems being modelled, rather than computational details. The most powerful embodiment systems are object-oriented hierarchies based on key theoretical concepts, such as directed graphs, cellular automata, and neural nets. Benefits of the embodiment approach include simplifying the development of simulation models; permitting the use of formal languages as modeling tools; and stimulating the development of theory in particular areas of application.

Simulation as a cure process design tool for aerospace materials
Article Abstract:
Composite aerospace materials, known for their good mechanical properties and low weight, present interesting cure process design problems to the engineer. It is shown that computer simulation can be used as a powerful tool in solving these problems. Using physical principles, simple mathematical models are constructed which describe observed phenomena. With the advent of high-speed microcomputers and desktop workstations, the simulations can be run at low cost. It is shown that with a properly validated model, the process engineer can use simulation to efficiently optimize cure cycles, as well as map undesirable operating regions. Examples are presented, which show that "standard" cure cycles for these materials can be modified to shorten processing times. Also, conditions which could cause reaction runaway are exposed.
