The EMI conduction coupling has more serious influence on the sound response than the EMI radiation coupling, and the noise linearly increases with the decrease of distance to the EMI source. The shielding capacity and routing design of the cables are significant...

... are increasing. In the mooring system of offshore engineering, the conventional method to monitor the breakage or not of mooring cable is to arrange a certain number of sensors to evaluate whether the mooring cable is intact or not by measuring the physical tension. However, the accuracy and reliability...
