The combination of the functions E and R seems to indicate that the system should be shut-off once there is a slight indication that there is a virus present. The average long-term connectivity with this control is 0.84. With this security system in place, a typical decay in connectivity is shown in Figure 7. After an early drop as a result of the detection of the virus, the connectivity flattens out, that is, the virus has been found and contained. The state transition function H used by the filter.
E moderates the output of the detection system.
The roughness of the curve is due to errors in the detector.
