Experimental on the JAFFE database results show that the method is effective for both dimension reduction and recognition performance in comparison with traditional PCA and ICA method.
However, before applying a fastICA algorithm on the data, it is usually very useful to do some preprocessing, such as centering and whitening, which make the problem of fastICA estimation simpler and better conditioned.
After estimating the mixing matrix with centered data, we can complete the estimation by adding the mean vector of back to the entered estimates of.
Since the data is sphere, a reasonable approximation seems to be .
Two facial expression images of each expression of each subject were randomly selected as training samples, while the left one samples were used as test data.

To achieve accurate forecasting, the study utilizes data from newly connected domestic customers and their corresponding sanctioned loads from service centers in Bahir Dar (Bahirdar1 and Bahirdar2), Adet, Anbesamie, and Merawi. 2.2 Dataset Preparation Data collection began in May 2019, coinciding with EEU’s transition from a manual billing system to an Enterprise Resource Planning (ERP) system, ensuring data accuracy and reliability.
The data collected is below in Table 1.
Using this data, it regulates an oscillator to produce an output signal that remains synchronized with the reference signal[15].
Monthly diesel consumption data from the EEU Bahir Dar District reveals an annual operating cost of 571,663.35 ETB for the generators.

Noise reduction can use kalman filter and wavelet filtering method.
They are descriptive data mining analysis and prophetic data mining analysis
(1) descriptive data mining based on summary of data describes the general properties, providing normal character of data.
Common descriptive data mining analysis methods include anomaly detection, gathered and so on; (2) prophetic data mining is the data analysis by establishing a or a group of model.
Statistical model can learn from the actual data, the typical representative is neural network and data mining system[13].

Based on the defined shape of the inducer by use of 3D-CAD system, the developed CAM system finally generates interference-free NC data for 5-axis control ultraprecision Fig. 7 Inducer to be machined Fig. 8 Configuration of the inducer Fig. 9 Collision avoidance between a diamond Fig. 10 Cutting simulation milling cutter and a workpiece milling, taking account of the collision between a diamond milling cutter and a workpiece, as illustrated in Figure 9.
Before machining, cutting simulation is performed on the basis of generated NC data, whose result is shown in Figure 10.
From the simulation, it is confirmed that the generated NC data can manufacture the inducer.
As the demand to rapidly produce microparts, the reduction in lead-time to machining will be strongly requested.

On the other hand, the increment of foundation load and reduction of foundation bearing capacity can be caused by some reasons, such as surrounding environment changes and function changes of building,accident.
Low Strain Dynamic Testing Techniques.The method of low strain reflected wave is applied to test the integrity of pile body.Plain concrete pile of composite foundation is chosen to low-strain dynamic testing.Compare the test data before and after foundation construction,the feasibility of low-strain dynamic testing testing technique used in existing ground is verified.The in-situ low-strain testing curve of existing foundation can be seen from figure 6,while dynamic testing curve after completion of pile can be seen from figure 7.
Many domestic and foreign scholars gain data through the in-situ measurement technology and statistics analysis, foundation bearing capacity of existing building obtained.It is lack of test data and system test methods and evaluation technology.

The accuracy of the curve fitting can be gauged by a comparison of the actual experimental data with the model predictions in Fig. 4. . (4) Hysteresis under Varying External Loads.
Fig. 6 shows the stiffness data of 2 kinds of McKibben PAM, manufactured by Festo and Shadow Robotic Co.
This leads to a higher temperature and a reduction in the viscous damping.
Table 3 shows this phenomenon – at a maximum voltage of 3 v (or 6 v), the data shows that the maximum contractile length of PAM first increases before it decreases.

In order to compare them, the data from Korea were changed to the pattern of reduction factor depending on temperature differences.
Therefore, the Eurocode 3 appears to be more conservative but there are no significant differences when the tested mechanical data is used.
(1) In terms of mechanical properties, at a lower temperature range the tested data was more conservative.

Introduction The automotive industry’s focus on energy saving and emission reduction has generated great interest in hot forming as a manufacturing method [1].
Finally, compare simulation results with experimental data.
Blank initial temperature is 720℃; quenching time is 15s according with experimental data.
Other parameters are also comes from the experimental data.

The first stage is added using the elaborated methods of data and knowledge acquisition.
Additionally it was proposed the method of data evaluation.
Fuzzy analysis of prepared set of design requirements One of the methods of complexity reduction in design action is the proposed fuzzy analysis of the set of design requirements.

Experiments using automatic program-controlled test system, PC computer as the host controller, IEEE 488 bus for data communications, With HPVEE software programming, and this Program is used to control the HP6625A dual output power and HP3457A multimeter.
Analyzing the measured data into data files, and displayed on the screen.
The reduction of Ib has linear relationship with the number of hot carrier, and has exponential relation with the energy of hot carrier.
