Assured and correct dynamic update of controllers

Mostrar todas las versiones(2)

In many application domains, continuous operation is a desirable attribute for software-intensive systems. As the environment or system requirements change, so the system should change and adapt without stopping or unduly disturbing its operation. There is, therefore, a need for sound engineering te...
