The energy saving and emission reduction is of most importance.
The traditional method to solve the unit commitment(UC) problem of wind power needs to know the output data of wind farms.
As the candidate individual, the fitness function is expressed as: (14) Numerical Example For Considering Emission Reduction In this paper, 10-unit 24-period system[12] and the wind generators[9] are adopted.

This effect on wear is mainly due to reduction in surface contact area between the mating wear surfaces also effective transfer of wear debris from the wear medium.
1.
The tool during machining experiences high wear and friction due to the forces involved leads to reduction in tool life.
Wear rate, Friction force and Co-efficient of Friction are constantly stored by a data acquisition software package integrated with the device.
· High reduction in wear and friction even running at high load and temperature than non-textured surface was seen on linear textured surface which is mainly due to reduced surface contact area
· Reduction of friction during increase of sliding speed is mainly due to the slip phenomenon between the mating surfaces.

The results showed that the hydroxyapatite could be a promising alternative for the reduction of Na+ concentration in waters from saline soils.
From the diffractograms, it can be observed the change in the Hap crystal structure, evidenced by the reduction in the intensity of peaks.
The intensity reduction of peaks can be attributed to the dissolution of calcium without the occurrence of ion exchange. 2θ Fig. 1: X-ray diffractogram of the solid samples at different immersion time.
Figure 2 shows the curve that represents the resulting average for the concentration reduction analysis of sodium ions in the sodium chloride solution as a function of time.
Such phenomenon corroborates with the data recorded in Table 1, which shows the pH variation over time.

China is now currently facing serious international emission reduction pressure and economy development energy environment restriction.
Japan proposes this goal because Japan is a country of waste material source and good reduction.
According to 2012 Japanese environment province statistics data, we will analyze 2010 Japan waste total emission amount of 385988 tons, and finally, it is through direct cycling processing, middle processing and final processing, it obtains 204733 tons of energy.
The work of energy-saving emission reduction in Jilin Province is seen in garbage classification recycling, and the author thinks that the current existing problems are as follows. 1.
In order to avoid the above problems, when the government conduct low carbon economy and energy reduction emission work, it should focus on common people’s daily life.

Each datum point represents the average of at least six readings.
It is observed that the hardness increases with hot rolling reduction ratio.
At lower hot rolling reduction ratio, it is observed that both hardness and impact toughness are increasing with high fluctuation in readings with decreasing hot rolling reduction ratios.
However, impact toughness decreases with increasing reduction ratio.
Reduction Ratio in all alloy samples in Fig. 2(c, d) around ~6%.

Simultaneously, the viscous coefficents denoting the viscous behavior in visco-elastic constitutive model were determined by taking use of the creep testing data.
The carbon cathode is the most critical component in aluminum reduction cells, that is to guarantee the structural integrity and safe operation of aluminum reduction cells has a crucial Significance[2,3].
Combined with the data of sodium expansion that have been investigated extensively [13], the creep behavior can provide key information in cathode material selection and cathode structure design for prolanged cell service life [14].
The measured data are fitted into Eq.(3) in the Matlab software.
The viscous coefficients denoting the viscous propeties in viscoelastic constitutive mdoel are determined by using the creep test data, and fitting creep curves of carbon cathode is compared and analyzed, which shows that the proposed rheological model can discribe the creep rate at the first stage and the stady-state stage on the creep strain curves.

Prevention and
reduction of waste by introducing appropriate measures should be a major aim.
The discontinuous nature poses a difficult problem in the sequencing and scheduling of tasks of manufacturing different products, the reduction of waste generation and energy conservation.
Rapid low cost reduction in waste generation can often be achieved through changing set points or tightening control variations of key variables 3.
After the assessment phase, which includes data collection, organization of data, flowsheet production, identification of significant waste generation practices and site review, exact mass and energy balances have to be produced.
The data are given in Tables 1 and 2.
