# Terminology

In the lack of consistent terminology for IO systems in the scientific community, MARIO uses its own customized variable names. MARIO follows a thermodynamic way of nomencluture which:

Uppercase letters represents Flows

Lowercase lettters represents Coefficients

Following table represents the variables and their explanations in MARIO:
