S2 is an accepting state, however we do not know the length of the input string, so it is possible to exit from the accepting state if the input continues If we want to present a

if a thread is inside a critical section on a given resource all other threads are blocked upon entrance on a critical section on the same resource. We will study such techniques in

Il sistema deve essere in grado di rispondere agli eventi esterni (sistema reattivo) entro un certo tempo limite

a critical section is a sequence of operations that cannot be interleaved with other operations on the same resource two critical sections on the same resource must be.

the parts of the code where the problem may happen are called critical sections..

For every subset of states that are reachable from the start state of state of A with a certain symbol, we make one transition in B to the state corresponding to the sub-set.

An action to be performed if the transition is activated and enabled, just after the exit operation of the leaving state, and before the entry operation of the entering state Only
