A decision support system (DSS) is implemented to determine the optimum inventory levels for the demand data and for the scrap.
The demand and the scrap for each time period are tabulated as per the pervious history data.
= The total number of data present in the record set or the total number of records that have been collected from the past.
The demand and the scrap data collected during the study period is tabulated in Table 1 and Table 2 respectively.
The demand data input is given to the GA module to find the optimal inventory stock as shown in Figure 3.

Experiment of data show that by avoiding the vapor pressure of crucible a sintering at 1380℃ causes the silicon powder easily to sinter to high density, without the use of any doping addition.
At that time, the source of silicon monoxide is from the reduction of silicon oxide by using silicon powder.
Both suggestion although have not enough data to proven our suspect, it is clear that the future work will uncover the explanation.

It mainly consist of data preprocessing, data mining and data evaluation[3].
The data preprocessing can define as the operations as followings: data cleaning, data integration, data conversion and data reduction.
The purpose of data preprocessing is to eliminate data redundancy and data inconsistency, and guarantee data integrity, which finally forms data warehouse in favour of data mining.
Data mining is a crucial part of data processing of knowledge service platform.
Knowledge discovery is very complicated information, data journey of discovery results, which need to have a flexible model base of data mining and additional uses of wide spectrum of tools by repeated operations.

Figure 1 Region of interest (first: before compression, last: after compression of 28% reduction, middle: intermediate steps of ~5% difference in reduction).
The crystal orientation data described by Euler angles are further converted to quaternion representation and the in-plane rotation representation was achieved by projecting it along z-axis for a better comparison with the rotation result calculated by DIC [4, 5]. 5% 15% 28% Figure 2 Compressive strain maps (above) and rotation maps (below) around particle at different stages of compression.
Figure 3 (Left) EBSD misorientation map in the same region in Figure 2 with ε=0.33 (Red, Green and Blue colours are corresponded with the Euler angles between a reference pixel and the other pixels) and trace of {111} plane and (right) in-plane rotation calculated from EBSD data particle shape is outlined in green.
When the deformation goes up to 15% and 28% reduction, the strain in slip bands are up to almost 50% and 80%, with only ~10% in the between.
These agree with the EBSD data shown in Figure 3.

For the measurement of hydroperoxyl/superoxide anion radical concentration, the well known method based on ferri-cytochrome c reduction was used [11].
These data were collected at a power density of 1 W/cm2, with and without the single band filter in front of PMT.
For calibration purposes, ferro-cytochrome c was produced from the reduction of ferri-cytochrome c by sodium dithionite.
From these data, an average generation rate of 1.60 µM/min was calculated at ~ 27 °C.

Therefore, YSZ minimizes the electronic conduction of GDC as well as protects the reduction of Ceria ions [3].
All data shows clear peak of yttrium and zirconium.
Comparison with other experimental data based on Ceria based electrolyte cell, our experimental results has enough potential[7].
We can conclude potential of this experiment from OCV data achieved by YSZ/GDC bi-layered cell.
YSZ thin layer seems to perform well to block reduction and electron conductivity of ceria.

With the rapid development of emerging applications and data transmission rate in LTE (Long Term Evolution) system, terminal power consumption is becoming seriously.
On the basis of the DRX semi-Markov process and ETSI data model, formulas of power saving factor and wake-up delay for adjustable LTE DRX are derived.
A new method of DRX mechanism model which adapts burst data packet service is proposed in [3].
But in sleep period UE should shut down the power of transceiver and stop receiving/sending data.
Powering saving factor and wake-up delay We adopt ETSI bursty packet data traffic model [9] to use in DRX semi-Markov process.

According to data released by the Ministry of Energy and Mineral Resources of the Republic of Indonesia, coal reserves in Indonesia are estimated to run out in 2036, oil reserves in 2028, and gas-phase fuel in 2027.
The weight reduction was almost 58% upon heating to 350 °C.
This mass reduction occurs due to the heat distribution by conduction in the furnace.
Based on the activation energy values in Table 1, it can be seen that the activation energy corresponding to the data value is at the R2.

The reduction in mean forming load when ultrasonic vibration is applied to the die was attributed to several sources: the reduction of friction between die and specimen interface, stress superposition, absorption by dislocations of the ultrasonic vibration energy, acoustic softness.
This may lead to a fictious impression of friction reduction.
The numerical simulation agrees well with the experimental data during the first stage superimposed with ultrasonic vibration (T1).
It can be seen that the FEM data is bigger than experimental data when the engineering strain is equal to 0.4 while they are almost equal when the engineering strain is equal to 0.22.
It can be explained by the reduction in friction coefficient.

This paper presents an analysis from small hole DHD with scCO2+MQL in comparison to high pressure (HP) soluble oil coolant to provide viable data for furtherance of the technology.
Hole diameter data for each trial consisted of eight data points (every 10th hole in a total of 80 holes drilled per setting).
PC-DMIS software was used to collate the measured data.
The data indicated that both CLF conditions remained well within a surface roughness tolerance (Ra) of 1.6 µm.
The analysis of hole diameter data from every 10th hole drilled for each feed rate (fn)/spindle speed (n) variation, revealed the following results: Run 1 and 6: (Figure 6) Both cooling methods produced holes within tolerance, with HPC consistently mid-tolerance, and a gradual reduction in scCO2+MQL hole size.
