Among them, the values of should be set according to the expert advice or history data.
First step, selection of the sample data. the sample data should be from the same area and have the same technical conditions of the related real estate development projects.
M function files include foraging behavior, group behavior, following behavior and random behavior. according to the sample data, solve the optimal solution for the parameters a, b, c, min(a,b,c)<0.01 is for the algorithm termination conditions, and 0.01 is the tolerated error.
The evaluation results The classification criteria of evaluation results are in Table 2, the specific levels can be divided according to the average grade of each evaluation index in historical data, or can also according to the expert advice.
Depend on the carbon reduction ability of developers to give preferential policy.

With the anti-shear parameters reduction, the nonlinear strength reduction FEM model of slope turns to unstable status and the numerical non-convergence occurs simultaneously.
Efficient and accurate, the strength reduction FEM is feasible to examine slope stability and analyze slope movement patterns.
This can be determined either by statistical method, which analyses the correlation between the observed loads and deformation data, or deterministic method, which utilizes information on the loads, properties of the material, and physical laws governing the stress-strain relationship.
At that point, the limit reduction factor obtained based on c-φ reduction algorithm can be regarded as equal to stability factor obtained using limit equilibrium method[8], the method can be expressed as Eq. 2, in which the F is the reduction factor, also is equivalent to the safety factor.

The temperature 1150°C was chosen on the basis of preliminary reduction experiments in the muffle furnace and according to the data of the thermodynamic analysis [11-12].
However, the iron reduction was incomplete.
For complete reduction of iron, it is needed to increase either temperature or time of reduction.
Thereby, only increase in reduction time is possible to perform the complete iron reduction.
Phase composition of ore after reduction (Fig. 2).

The experimental result of the flow drag reduction tested on macro-scale channel in laminar flow is very well, and the maximum drag reduction is 25.6%.
This phenomenon has important significance on drag reduction of super-hydrophobic surfaces.
Conclusions based on the findings are drawn: (1) In the normal channel, the experiential data of flow pressure drop is consistent with the theoretical values when Re≤2000; (2) In the super-hydrophobic channel, by the fitting experimental data curve, the friction factor can be calculated by the following equation: (7) Comparing with eq. (1), we found that the drag decreased by 25.6% in the channel with micro-nano structured super-hydrophobic surface channel.

The calculated band structure data of the Fe-CDs are summarized in Table. 1.
The band structure diagram of Fe-CDs obtained by combining data from Tacu and MS (Figure 6d) shows that the conduction band potential of Fe-CDs-13.0 is more negative than that of ScCDs, which suggests that the reduction ability of Fe-CDs-13.0 is enhanced.

Table 2 Related electricity data (kWh) (kWh) 1.764 0.046 0.5 0.25 In table 2, we can find the anddata of Beijing subway line one in 2011.
Calculation about the year oil consumption of bus and car: Table 4 Beijing road transportation condition in 2011 (L) (L) 0.4-0.5 7-10 0.38 28% 16.5% Note: data come from Xinhua news network.
China produces 22179000tce sulfur dioxide for the whole year, from the above calculation, one line subway in Beijing can save 19700tce sulfur dioxide, the assume that there are ten lines subway, the data may be 6-10 times larger.
From these data, transportation may be a section needs more attention to reduce emission.
So except for , other known data stay the same.

An Investigation on the Solid State Reduction of Chromite Concentrate A.
Identifications of the peaks were carried out by matching of the diffraction pattern and peak relative intensity with those found in the JCPDS data file using the APD programme.
The amount of mass loss during reduction therefore indicates the quantity of carbon monoxide released during the reduction and it is directly proportional to the mass of oxygen lost from the reducible oxides, and hence to the degree of reduction.
Reduction of chromic oxide to metallic chromium, after the reduction of iron, the remaining spinel consists of chromium, magnesium and aluminium oxides.
At 1300 C for 5 h, 73% reduction and 1400 ºC for 1 h 58% reduction were obtained in the mixture of chromite with metallurgical coke.

To achieve the aims, it was decided that the key parameters of the soft reduction which is soft reduction zone, total soft reduction amounts and reduction rate in the given soft reduction zone.
The proper soft reduction zone is the most important precondition to achieve the ideal effect in soft reduction practice.
The calculated values of solidus were compared with the data in dynamic secondary cooling model database in present work.
The calculation results with non-equilibrium solidus are basically consistent with pin shooting experimental data, and the max error is 5mm.

Due to its high speed data rate and its ability of multipath fading channel robustness.
These services carries high data rates in wireless communication system.
OFDM has its major benefits of higher data rates and better performance.
High data rates are achieved by multiple carriers and is performance improvement is caused by the use of guard interval thus mitigating ISI [1-4].
