From the training data, create a bootstrap sample Z of size N. 2.
A decision tree doesn’t always require data to be normalized or scaled.
With inadequate data, the decision tree approach can be used.
With experimental data, we compared the results of the four models.

What are prepared in the test are Cu and nickel particles, with particle size of being 10 ~ 100nm.Major preparation methods of Cu nano-particles are gas evaporation, mechanical and chemical, plasma, gamma-ray radiation, and liquid phase reduction methods, etc.
Condidering that the other preparation methods need more complicated equipments and processes, this test makes use of the liquid phase reduction method.
The liquid phase reduction method generates copper particles through the reaction of the reducing agent HCHO and the Cupric hydroxide solution.
After several tests, we obtain the data shown in Figure 6 and Figure 7: Figure 6.

With a suitable scheme of neutral temperature and comfort air speed, reduction of energy consumption of the central chiller plant may surpass the additional energy requirement of the air side equipment, then both energy saving and thermal comfort can be achieved for the entire air-conditioning system.
The dataset consists of 30,000 buildings (10,000 office buildings for each of the three major climatic zones) with their detailed constructional and operational data and of their simulation outputs.
In Thailand office buildings, when the ambient temperature varied between 26.6 and 33.5 ºC whereas the set-point temperature varied between 22 and 28 ºC, Yamtraipat et al [12] reported that the mean energy consumption is about 6.14% reduction corresponding to a 1 ºC increase of the set-point.
(c) In the hot and humid climate, the 1 ºC increase of the set-point will lead to about 6% reduction of the mean energy consumption.

In fact, CO2 emissions reduction constitutes a must in transportation industry and not only.
The specimens were compressed, up to a height reduction of 50%, in isothermal conditions in the temperature and strain rate ranges of 473K–513 K and 0.00025s-1 - 0.025s-1, respectively.
The measured data were then compared with the so-called calibration curves, as shown in Fig. 1, which were constructed from the finite element simulation results [10], and the values of friction factor m could be evaluated.

Only a little part of the organics could be removed out of the polluted environment through physical and chemical methods, such as dilution, diffusion, volatilization, oxidization, reduction and neutralization.
The average data were shown in the following table 1.
The figures in Table 2 lead us to the conclusion that biostimulantⅠhad a better performance and stability than biostimulantⅡand blank, particularly in turbidity reduction.
Focus on single index, the removal rate of turbidity was the most, NH3-N and CODCr reduction were not obviously.

Autothermal thermophilic aerobic digestion (ATAD), a kind of special aerobic digestion, is capable of achieving a high degree of stabilization and pathogen reduction to produce Class A biosolids under the condition of a thermophilic temperature (45~650C)[2,3].
Accordingly, the objectives of this study were to investigate sludge stabilization and reduction by indexes of VSS, TSS and auto-rise temperature.
The ATAD system used an on-line oxidation-reduction potential (ORP) as an indicator of the aerobic character.
The indicators were determined as the test data.

Ridges at the edges can cause short-circuits in OLED devices or reduction in the working longevity and efficiency of the devices.
The reduction ratio of objective lens is 10:1.
The chemical wet etching processing is favorable for the reduction of the recast ridge at the edges. keep the excimer laser fluences as 5.81 J/cm2 and the translational speed of working platform as 10 mm/min to fabricate two ITO electrode patterns on two ITO glass sheets.
Results and discussion The microstructure of ITO electrode patterns was viewed and measured with non-contact 3D surface profiler (Wyko NT1100,Veeco Instrument Inc., USA), and the data were analyzed and simulated using WYKO Vision32 software(WYKO Corporation, USA).

Recycling and re-manufacturing activities are done by the manufacturer, due to the manufacturer's salable product inventory part from remanufacturing, a direct result of the reduction in the number of suppliers, resulting in a reduction in the interests of suppliers.
Demand forecast For manufacturers, whether the production plans or parts procurement plans are based the forecast on the basis of good market demand, taking into account the characteristics of the system data exists volatility, but no significant growth trend, using exponential smoothing method to predict demand, exponential smoothing formula is as follows: (1) Do z-transform, (2) 3.1.2.
The supplier market demand will be reduced; it will also bring about a reduction in the amount of the production and procurement of suppliers. 50 weeks, reaching the product life cycle of the product is recycled for re-manufacturing activities, and assume that the process of recycling and re-manufacturing is no time delay, the manufacturers of new products production and purchase volume and instantly dropped, and maintain in a stable value.

RESULTS Metallurgical results The laser procedure leads to a reduction in size of the grains in the weld zone and the presence of a high crystallographic texture only in the surface of the weld line, the main orientation of which is as follows: {101 1} 3 41 3 (58 % of the grains) [3].
It can be seen that the profile had a zigzag pattern and there is no clear tendency from the experimental data.
CONCLUSION This study shows that laser welding profoundly modifies at a local level the metallurgical (reduction of grain size, presence of a texture at the surface of the weld line) and mechanical state of moulded sheets of AZ91 alloy.
The complexity of the association of thermic, metallurgical and mechanical aspects has shown by observation a superficial layer where the presence of a strong texture is accompanied by a reduction in the intensity of the residual stresses which are maximal only in the sub layer.

According to the shaking table experiments on seismic isolation layers made in various operating mode, the dynamic characteristics, relative displacement and acceleration reduction with different layer height and input acceleration amplitude were investigated.
It is to be mentioned that more reduction occurs with increasing layer height and input acceleration amplitude.
The test result indicates that the acceleration reduction coefficient of crosswise is 57.6%, while 66.6% of the lengthwise, which is basically consistent with proposed data.
