There were 5 samples in each group of test, and an average value was determined on the basis of the five measured data for each group.
Based on these data, two promising candidate LP parameter sets were evaluated, and the most optimal LSP parameter was chosen.

This leads to a reduction of probability to high DGD values, but without any maximum limit.
Fig.3 The experimental setup for adaptive PMD compensation We got a data table achieved from the adaptive PMD compensation experiment depicting the relationship between DOP and variable voltages of the polarization controller.
Then, we tested DPSO and PSO algorithm using this data table by simulation.
Our aim was to find the best DOP in the data table.

The impact force measuring system consists of BK-2B unidirectional force cell, signal amplifier, PCI-8360 data acquisition card and special processing software.
In this research, to increase the information amount of experiment data and to enhance accuracy of the prediction model, the orthogonal experimental design and regression analysis method are used to establish the impact force model.
Therefore, the inner pressure of micro-detonation will decrease, causing the reduction of impact force.
Using data in Table 1, the test results can be obtained and are listed in Table 2.

Gabbay and Mehner et al. used polynomial functions whose coefficients were identified using strain energy data to model a microelectromechanical system[3].
The form of this polynomial can be written as: (4) Where U is the strain energy functional for the system, the coefficientsare found using a least squares fit of strain energy data generated using a finite element package and the are the Lagrange basis functions.

These data must be on elements features that influence cycle performed by product during life.
These data will be completed for each component.
In the next stage, in SimaPro program menu, necessary data for the recycling of each component are inserted.
Moreover, the precision of analysis of life cycle depends on the accuracy of collected data.
A life cycle analysis is viable only if data used for analysis are also viable.

This is mainly caused by the lack of data in order to evaluate the process economically and differentiate it to other processes like arc and laser welding, also regarding technological factors.
Breivik [9] investigated the same material and obtained a total strength reduction in the HAZ of 43 and 34% for GMA and FSW samples, respectively.
As can be seen from the progress of the values, the spindle torque reaches an area of saturation at more than 3000rpm, which is assumed to be caused by a reduction of the coefficient of friction due to local melting and change in the stick-slip-condition.

Furthermore, Rubaai [7] describes a computer program yielding an optimal design of a distribution transformer based on user input data.
Data Input Two groups of input data must be defined by the user, prior to the transformer design optimization process, concerning: i) the transformer technical characteristics and ii) the mixed nonlinear programming methodology parameters.
These data are necessary for the execution of the algorithm and the derivation of the optimum transformer design.
The 3D FEM model incorporated in TDO software, developed in [19], is built automatically, using the geometrical data of the optimum solution and computes the transformer magnetostatic field under short-circuit test, according to its main electrical data.
For the above input data, 188 optimum designs were produced, using both methodologies.

Secondly, under consideration of the task balance, the processing unit for each charge on every working procedure is selected at random, and these data are saved on the gene segments of .
The comparison of the observed data of the practical process and the production plan of the simulation experiment is used to verify the algorithm and model.
Table 1 Comparison of the Average Staying Time of the Hybrid GA with the Production Data No.
By comparing simulation results with the practical data, it is observed that the optimization algorithm can achieve a performable and reasonable production plan for the SM-CC process.
