The proof is a routine diagram paste based on the definitions.
Level 2 contains both sequence and collaboration diagrams, which represent the same semantics only in different graphical notation.
From another point of view, the problem here is caused by the presence of identities (that is, empty pasting diagrams).
Takes the value of 1 if there was an organizational diagram of the proposed management and delivery structure of the bid, 0 otherwise.
Perhaps then more explanations, diagrams and a glossary could be included to improve a separate guide to syntactic analysis.
Since we are not assuming weak purity, the vertical map on the right of this diagram need not be injective.
As indicated by the bifurcation diagram (figure 3), the model system predicts zero value for turbulent shear stress in these cases.
At this point it will be convenient to introduce some abbreviations to save space in diagrams.
