SPTP — Suggested insertion at the beginning of the section 3.1

"Suggested insertion at the beginning of the section:Extracted from [5]:
« May be qualified as « real-time » every application operating a computing system which working is liable for the dynamic evolution of the environment state (so-called technique) that is linked to and which it has to control the behavior. ».
Extracted from [38]:
« Real-Time systems are those systems in which correctness of the system depends not only on the logical results of computations, but also on the time at which results are produced. ».
Both previous definitions of the term “real-time” give us following features of real-time system:

• A real-time system is tied up with its environment because it has to supervise its behavior via sensors and actuators;
• Its computations has to be of course right, but also has to be delivered at the right
