In fact for a given current function F the actual surface current density is (48) Comparing this with the definition of in (31) we see that the surface current distribution corresponding to the current function at radius s is just (49) Expressing (47) in terms of the surface current coefficient gives (50).
The inter-day precisions of the current method (coefficient of variation) are lower than 5%, while recoveries are more than 89.5%.
The values of current coefficients K1, K2 and K3 are 1.82, 1.79 and 1.9 respectively.
The values of the current coefficients K1, K2 and K3 are 1.8, 1.78 and 1.89 respectively.
Due to limited published data and range for extreme cases, the current coefficients do not apply to degradation of very aged phenanthrene nor very low concentrations of electron acceptors.
Thus, in the DRL for equal proportional current sharing and voltage restoration, illustrated in Fig. 4c and d respectively, the current proportional coefficients of all agents converge to equal consensus values, and the voltages reach a corresponding new state.
It can be seen in Fig. 6c that the current proportional coefficients of all DGs converge asymptotically to a new common value, and the synchronization seeking process is different from that of Case A because of the additional communication link.
Fig. 10 The differential current, restrain current and ratio restrain coefficient of the EBDP I. a The wide differential current of Bus I. b The differential current of Bus I Figure 10 indicates that the WCDP of EBDP I adopts the currents at the D1, D3, D5, D10, D11 and D16 to calculate the differential current.
