When to use system as countable-noun, and when to use system as uncountable-noun?
for Example: I wrote an article whose title is
"an XXX analysis for state prediction of process complex system (systems?)"
Another example, in the article, I wrote
"To predict the system state, XXX analysis is proposed to investigate the changing state of the system".
Is it correct thinking of the form of "system" or "systems"?
I am rather confused.
