Comparison of

relative error between Kriging method and BPNN, (a) temperature at flow front and (b) confluence angle.

Figure 5 shows (a) a comparison of the calculated and measured PHS values and (b) the corresponding

relative error for [P.sup.HS.sub.c].

In the section 4, we give the definitions of conditional filtering noise and expected data utility based on the absolute value of

relative error. Then we present adaptive Gaussian mechanism, it can achieve the expected data utility of noise response results, while satisfying differential privacy.

Mean

relative error, mean estimated error and chi-squared test were calculated for each mathematical model using the following expressions, respectively:

A CMOS controllable constant power generator based on the resistive mirror [1] has the range of generated power from 0.48 mW to 10.8 mW, and the load resistance dynamic range up to 28, with the

relative error of generated power less than 2.2% and the supply voltage of 10 V.

According to Table 5, the

relative error of the envelope method proposed in this paper is slightly greater than that of the direct method because the data points positioned by the envelope method are not on the simulation current curve, which results in the deviation between the locations of the envelope change points and the actual signal change points.

The charts presenting cumulative frequency of

relative errors on estimating regulated pressure enable quantification of the accuracy of the proposed model.

where RE(i) is the

relative error of sample i, [C.sub.cu-max](i) and [C.sub.cu-min](i) are the maximum and minimum inversion values, respectively, of the copper ion content for sample i when the water content changes among the six values described above, and [C.sub.cu-mes](i) is the measured value of the copper ion content for sample i.

To estimate sensitivity of differences we have used

relative error.

Relative error [[DELTA].sub.j] % of j-th performance indicator, can be calculated using following expression:

To be consistent with Plot (b) in Figure 2, where the

relative error has been represented on the spatial interval -4 [less than or equal to] x [less than or equal to] 1, here we keep the same interval to plot the

relative error.

Here, the constants c and n denote the cost and

relative error of the starting simulation, respectively.
