Places contain a finite space and restrict the number of tokens that can be placed at any time [12, 13, 14].
It's a finite situation here".
We are interested in the evaluation of the gamma ray which can skirt a lead (Pb) shield within a graphite medium and contribute to a finite detector, placed behind this presupposed perfect shield.
Imagine a game of tic-tac-toe, at any given point of the game, there is a finite option set (places you can place your "X" on the board. In that scenario, each move has an expected value.
There are finite resources and finite places to put waste.
The world, he would emphasize, is a finite, elegantly balanced place whose natural gifts must not be plundered.
A Petri net R is a quadruple < P, T, A, M > where: ▪ P denotes a finite set of places (containing tokens); ▪ T is a finite set of transitions (which specify how tokens move from one place to another); ▪ W ∈ (P × T) ∪ (T × P) →N is the weighted flow relation representing the arcs.
But infinite growth is incompatible with a finite planet, finite resources, a finite ecology.
(ii) P is a finite set of places.
