               The first input variable is vibration. According to Tables 13.6 and 13.7,
            the variable “vibration” is represented in Fig. 13.3.
               The second input variable is water produced by the generating units.
            According to Tables 13.8 and 13.9, the variable water is shown in Fig. 13.4.
