Reports issued by the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling in October and November, respectively, faulted the response by the administration of U.S. Pres.
Two experiments were accomplished, considering, respectively, fault-proneness of classes and methods.
The major branch faults are, respectively, called Fault F located at the center, Faults B1 and B2 for the relatively lower and higher angle ones at the shallow depth of the northern segment.
First, the current variation within a short time window is discussed respectively when fault occurs and PV operates with fluctuation.
The increase and reduction in fundamental components of faulty phase currents and voltages respectively after fault inception at 60 ms can be detected by ANN.
Because the main ruptures of these two earthquakes occurred along the different faults (Hinagu and Futagawa faults, respectively) and the faulting processes are also largely different (e.g., Asano and Iwata 2016), the observed different behavior in the aftershock activities is not surprising.
Fault-diagnosis schemes for T-S fuzzy model with unmeasurable premise variables were proposed based on a fuzzy PI observer and adaptive observer in [15] and [16], respectively, where faults are considered as unknown inputs in polynomials form.
They respectively simulate strong fault and weak fault modes of the bearing.
In particular, we focus our attention on the analysis of earthquake occurrences associated with two target seismogenic structures, Fucino and Ovindoli Pezza faults (hereafter F-fault and OP-fault, respectively), that are among the largest known in Central Italy.
The feature of spatial distribution of focal mechanisms is characterized by a uniform direction of P-axis while the faulting type is variable; predominant strike-slip events are distributed widely while minor reverse- and normal-faulting events are located to the northwest and near the center of fault, respectively.
Red solid and red dashed lines indicate precisely located active faults and inferred active faults, respectively (Nakata and Imaizumi 2002).
