We represent specifications graphically using the Temporal Logic of Actions, a logic that models system behaviour by sequences of states.
Open image in new window Fig. 3 Fundamental diagrams for pedestrian movement in planar facilities [Lines represent specifications given by planning handbooks (SFPE: Handbook, PM: Predtechenskii and Milinskii, WM: Weidmann).
By contrast, the remaining features are called abstract and they usually correspond to high-level features used for organizing the whole diagram (e.g., VSsystem), grouping sets of components and parameter variants (e.g., Tracking, Resolution), or representing specification and context aspects (features in the VSspecification sub-model).
This method ensures interoperability with existing engineering information management systems, represents part specifications in a formal manner, and has generality in search procedure.
An object diagram is a variant of a class diagram in which instance specifications are drawn, representing detailed specifications of objects of particular classes.
Model (2) represents the specification of the Probit model.
On the one hand, it represents a specification of the discourse principle for a particular kind of discourse (legal-political discourse).
This comparison represents the specification test of our model, in the same spirit as the comparisons of experimental and non-experimental partial equilibrium estimates in LaLonde (1986) and other, similar papers in the treatment effects literature.
The operations and relations of this algebra enable to represent controller specifications formally, to detect inconsistencies within specifications and to generate control laws from a consistent specifications set.
Many specification languages have been proposed to represent security specifications.
