Structural parameter identifiability is a property of differential model with parameters that allows for the to be determined from equations in absence noise. One standard approaches assessing this problem via input–output and, particular, characteristic sets ideals. The precise relation between and subtle. goal note clarify relation. main results are: We expect some these facts may known exper...

An alternative approach to developing reusable components from scratch is to recover them from existing systems. In this paper, we apply program slicing, a program decomposition method, to the problem of extracting reusable functions from illstructured programs. As with conventional slicing first described by Weiser, a slice is obtained by iteratively solving data flow equations based on a prog...
