... and the DBBLS signals is in the utilization of different sub- -0.5 carrier wave. The BOC applies some form of the rectangular wave while the DBBLS utilizes the harmonic one. The -1 spectrum of the BOC modulate signals are theoretically -1 0-0.5 0.5 1 unlimited, but in practical systems the signals are band- Delay [ ...

... refers to the ratio of correctly detected tunneled packets to the sum of correctly detected tunneled and incorrectly detected legal packets. Whereas F1 Score is calculated by taking the harmonic average of the precision and recall values, to be able to evaluate these two values as a single value. Besides, ROC curve of the proposed system ...

... [25]. In this analysis, these losses are initially estimated from the copper losses, the hysteresis, and the eddy current losses using the two-dimensional time harmonic finite element program using Matlab software. From the FEM analysis, the vector potential Az and the induced eddy current density in the rotor slots can be obtained ...
