A reactive layer, which has access to the system's sensors and actuators and provides reactive behavior which is robust even under environmental disturbances, for example with the help of closed-loop control.

Expert systems are not designed for reactive, proactive behavior.

A plant's concomitant reactive behavior is mediated by phytochromes, kinins, hormones, antibiotic or other chemical release, changes of water and chemical transport, and other means.

In computer science, coalgebra has emerged as a convenient and suitably general way of specifying the reactive behaviour of systems, including classes in object-oriented programming.

While the results are the opposite of what the influencer intended, this reactive behavior is the result of social pressure.

(Adaptive and reactive behaviours) Adaptive being the situation and reactive being the members.

The John Henry effect is an experimental bias introduced into social experiments by reactive behavior by the control group.

It allows specifying the reactive behavior, and the synchronous programming, of applications.

TPT was developed specifically for testing of continuous and reactive behaviour of embedded systems.
