This high temperature process is believed to cause some drawbacks including, especially, reductions in the thermal conductivity of diamond particles caused by direct contact with molten Al.
In the present work, to avoid the above-mentioned conductivity reduction of diamond particles, Al-matrix composites containing dispersed diamond particles were fabricated by utilizing a continuous solid–liquid co-existent state created during SPS processing [10-12].

The study presented that an increase in deposition rate resulted in reduction of the mechanical properties and micro hardness.
This reduction was the primary criterion to eliminate the defects due to increased heat input which affect the bead geometry and mechanical properties.
Minitab 17 statistical software is used for data analysis.

The effect of higher temperature at butanol’s combustion is diminished by cooling effect as a result of its vaporization, which would explain the reduction of NOx emission.
For data acquisition and processing, the stand is equipped with an AVL acquisition system.
This decrease is due to the reduction of the temperature inside the cylinder as a result of more intense cooling effect produced by the butanol’s vaporization.

Data preprocessing process Data Preprocessing Before Modbus TCP traffic gained from industrial control system is used for anomaly detection, it needs some preprocessing procedure.
Obviously, the method mentioned above used for data processing have a lot advantages.
Comparison and Analysis of Simulation Results Experimental Data Acquisition.
In the future, several fields in other industrial protocols could be handled simultaneously, and much work could be done in the aspects of dimensionality reduction to get data that both describes communication traffic efficiently and keep refined.

Moreover, data is also needed for calibration of the models.
When the primary interest in solute drag is its influence on the recrystallisation rate, it is a logical thought trying to extract data for solute drag from recrystallisation data.
Solid markers represent data from dynamic recrystallisation experiments, open markers from static recrystallisation both from [20], crosses represent static recrystallisation data from Yamamoto [21].
Experimental data are not always consistent.
However, available data are insufficient to test and calibrate models for austenite.

In addition, several advantages can be found on using RBFNN: simplicity of the architecture, reduction in training time and the capability to deal with unseen data [12].
Also, all the data were normalized in range of -1 to 1.
Moreover, to accommodate the noise may be present in the target data in the model and also to deal with limited training data employed, that may lead to ill-posed problem, Bayesian regularization was incorporated [19, 20].
It can be also seen that in general the RBFNN-NARX model prediction results can fairly follow the experimental data trend.
The accuracy of the RBFNN model prediction compared to the experimental data was measured in mean squared error (MSE).
