The binary adjacency matrix is created by applying a user selected correlation threshold (|rP|) to the gene by gene correlation matrix.
Equation (11) can simply be executed on the same complex multiply-accumulate (CMAC) unit used for FBD in Figure 7a Memory requirements here depend on the selected correlation window length with a maximum of 256 samples as stated before.
Changing the API of the oil by ± 10% had slight effect on both the expert system selection and the calculated pressure drop by the selected correlation.
5. European Patent 1,105,991, entitled "Communication Methods and Apparatus Based on Orthogonal Hadamard-Based Sequences Having Selected Correlation Properties," asserted against mobile devices, together with base stations, operating according to the UMTS telecommunications standard.
The validation results also show that even in the cases where the best correlation was not selected by the expert system (30% of the cases), the selected correlation always produced reasonably good results compared with the actual values (i.e., when the expert system fails to select the absolute best correlation, it will select one of the second best correlations).
Other parameters were investigated to check their uncertainty on the expert system and the error of the calculated pressure by the selected correlation(s).
The most important quality criteria are summarized in Table 7, selected correlation graphs are shown in Fig. 4 and all the validation reports are in (Additional file 5).
A comparison with selected correlations in the literature showed that the developed ANN correlation noticeably improved prediction of overall gas holdup.
A comparison with selected correlations in the literature showed that the developed SVR correlation noticeably improved the prediction of pressure drop over a wide range of operating conditions, physical properties, and pipe diameters.
A comparison with selected correlations in the literature showed that the developed ANN correlation noticeably improved prediction of hold-up over a wide range of operating conditions, physical properties and pipe diameters.
