Optimal temperature profiles for methylmethacrylate polymerization in the presence of end point constraints

Optimal temperature histories have been obtained for methylmethacrylate polymerization using a kinetic model incorporating gel and glass effects. The minimum end time problem has been studied, with end point constraints on monomer conversion and the number average chain length, μ_n. The optimization algorithm used is efficient and easy to use. It is found that the optimal temperature histories obtained when the desired chain length lies beyond the maxima in the μ_n vs. time plot differ qualitatively and significantly from those obtained when the desired μ_n lies before the maxima.     

Data flow. Opening the door to better ways of working in parallel

The authors begin by setting the scene as to what data flow computing is. They go on to discuss data flow languages and give a graphical data flow program example
