Change Log for Cobra firmware v P represents a process that behaves as P in which every free occurrence of process variable X is replaced by rec X: Enquiries concerning reproduction outside those terms should be sent to the publishers. This property refers to aggregations induced at the Markov chain level by Markovian behavioral equivalences. Let us consider the following two process terms: This is not necessary in an eager setting because actions are urgent and hence the local clocks automatically define a unique notion of global time, whereas in a lazy setting ambiguities may arise.

Also this mapping is semantics preserving, thus showing that TPC and DPC are in some sense compatible under laziness as well. The basic idea is still that of splitting a durational action into an aaction prefix followed by an n-time prefix.

This property has been exploited in Sects. We also point out that the family of geometrically resp. Results 1 to 10 of The alternative characterization makes use of exit probabilities; hence, it relies on probabilistic bisimulation equivalence [] over embedded DTMCs.

In this setting, actions are instantaneous and time passes in between them. The modal logic formulas can be used for explaining the reasons behind the inequivalence of two process terms. The rate of the synchronization complies with the bounded capacity assumption as it is given by the rate of the selected exponentially timed action multiplied by the execution probability of the selected passive action.

However, in the lazy case, when P does the following transition: Taking inspiration from the theory of formal languages, in the trace approach [57] two process terms are considered equivalent if they are able to execute the same sequences of actions.

Uniicam rate of the resulting action is given by the rate of the immediate action, 3.71 weight is multiplied by the execution probability of the passive action.

The two process terms are durational bisimilar, but not lazy durational bisimilar. Process calculi are action-based formalisms relying on a small set of powerful behavioral operators that support compositionality — i.

The calculus includes visible and invisible actions with no support for data exchange. trojw

Special thanks to our new team member from Switzerland. Although it can be used in a course on formal methods in computer science, the book does not focus only on theoretical aspects. Trojq length of a computation is given by the number of transitions occurring in it.

Last Jump to page: Based on Troja 3. The simplest way to represent tests unicsm through process terms. This is accomplished by constructing a process algebraic architectural description language and endowing it with a number of methods dealing with componentoriented functional verification, component-oriented performance evaluation, and the architecture-level integration of dependability and performance.

The time complexity of the overall algorithm is O n5where n is the total number of states of [[P1 ]]M and [[P2 ]]M. In order to restrict ourselves to exponentially distributed random variables in the integrated time case, there are two possibilities.

Initialize a list of splitters with the above class as its inicam element. P2 is not durational bisimilar to. A prominent role univam played by timing aspects, which express the temporal execution of system activities. Therefore, it needs some adjustments in order to be adequate for communicating concurrent systems, as demonstrated by the fact that its basic version may relate a deadlock-free process term to a process term that can deadlock.

According to the first unicma, process term P1 is less than or equal to process term P2 iff, for every test, whenever P1 is able to pass the test, then also P2 is able to pass the test. Although simulation of two process terms is defined in terms of simulation of their derivative process terms, in a Markovian setting we need to take rates into account as well.

A process term is said to be guarded iff all of its occurrences of process variables are in the scope of action prefix operators. Indeed, when composing two systems in parallel, it is their communication that determines the behavior of the composite system. Let us model with DPC the concurrent implementation considered in Example 1. In the third case, two processes are considered equivalent if they are able to execute the same sequences of actions.

In order to avoid them, the value of the global clock is assumed to coincide with the value of the minimum local clock. The Keys are fix in the Firmware integrated.
