The responses of the monitoring methods to a prolonged simulated loading using recording sampling time of 0.1 s. a Responses to a simulated pressure input ranging between 20 – 25 kPa. b Responses to a simulated repetitive input with period 30 min and range between 0 – 20 kPa. See Fig. 1 for the description of the annotations
