In order to establish the type of band-to-band transition present in these LDZ powders, the absorbance data of the DRS spectra was fitted into equations for both indirect and direct BG transitions [32,33].
Using the Eq. (3) and the data of Table 3, the initial degradation rates (r) of MB over Al (0.5%) and Li (0.2 to 2%) co-doped ZnO catalyst formed at 450°C for 5 h were calculated.
It can be clearly seen from the data of Table 3 that with the increase of MB concentration in the reaction mixture from 0.01 mM to 0.02 mM, the initial degradation rate (r) value is increased, and when the concentration increased from 0.02 mM to 0.03 mM, this r value is either decreased or remained same (within the experimental error).
The data of Table 3 indicates that 0.03 mM is the concentration that blocks the surface of the catalyst from light irradiation.
Considering this effect, initial concentrations were plotted vs. 1/kobs using the data of only 0.01 and 0.02 mM MB solutions to find out the values of Kads and k values from the data of slopes and intercepts with the help of equation 5.

Result shows that the built model matches well with the training sample data and thus confirms the effectiveness of the model.
The complexity of dynamic aerodynamic characteristic at this stage and the restriction from training data result in the poor capacity of the model to capture aerodynamic rules.
Thus, in order to obtain more precise prediction results, the scale of the training sample must be enlarged to enhance the training data range.
It can be seen that the simulation results are close to the test data and a good fitting can be seen.
However, too many input parameters and oversize data may result in the reduction of learning convergence rate of the network.

Principal component analysis (PCA) is a well-known statistical processing technique that allows
to study the correlations among components of multivariate data and to reduce redundancy by
projecting the data over a preferred orientation basis [5].
The central idea of principal component analysis is to reduce the dimension of a data set within which there are a large number of interrelated variables, while retaining the variations present in the data set.
These matrices, T and P capture the essential data patterns of X.
In order to make sure the shape prediction model is applicable for most kinds of rolling conditions, the data of 35 coils of strips, including 12740-measured point values, were selected from the strips rolled in one month as training data.
In addition, the values of 12 coils of strips, including 5187-measured point values, were selected as testing data that is different with the training data.

Differently, it is very simple to need only the test data from conventional fatigue cracking thresholds, growth rates, and fracture roughness values.

We compare the latest TLS experimental data resulting from fully processed 4H-SiC wafers with results obtained by mechanical dicing technology.
In Fig.6 results of throughput calculations of an industrial TLS tool (handling and alignment is considered) and throughput data from a mechanical blade dicing process are compared.
Fig. 6: Throughput calculations of an industry TLS-Tool compared with throughput data from a mechanical blade dicer for different chip dimensions (Wafer diameter: 150 mm).
This results in a reduction in process costs and in an increased uptime.

Furthermore, the new method, together with ACI318, ACI440 and GB50010 ones, are verified by nine test beams in three existing experiment and show a good agreement with the experimental data.
Based on the equations for deflection predicted in ACI318[4], a set of modified equations for FRP bars was provided in ACI440[5] and validated by a great deal of experimental data heretofore.
ACI440 approach Taking into account the tension stiffening effect, ACI440.1R-03[5] suggest the use of a modified version of the Branson formation as follows: (6) where the reduction factor bd equal to (7) where ab is the bond-dependent coefficient, Ef is the modulus of elasticity of FRP reinforcement and Es is the modulus of elasticity of steel reinforcement.
Fig. 2 Comparison of the predicted mid-span deflection using different methods and experimental ones from Pecce’s experiment Fig.3 Comparison of the predicted mid-span deflection using different methods and experimental ones from Alsayed’s experiment Predicted deflection The Four methods were validated by the experimental data from nine existing test beam series and compared with experimental results simultaneously.
