Second, we process the float data in the depth buffer by using uniformization and render the two depth data in the texture.Then use Gauss Filter to blur.Finally,use the algorithm of BIRCH cluster the uniformization data to improve the obscure and tweened effect.This method brings reduction of aliasing problem with low overhead as well as performance to a certain extent .
Otherwise, compute the variance from the two moments and scale the ray intensity.Usually the variance data is used to estimate the minimum boundary value .
So,The improved variance shadow map increases the global stability of the inputed data sets by reducing the threshold.The scope of the depth data sets is decreased for zero to one.And then,our normalized variance shadow maps' data sets are putted into CF tree,and then,We use CF tree of BIRCH algorithm to split the data sets into different clusters or different layers.This will reduce the gaps to some extent.The clustering of CF tree can be regarded as a recursion process.The detailed description of that algorithm is listed in the next paragraph.
BIRCH algorithm By using BIRCH algorithm [9],we can cluster mass data in a fast way.Mass data is divided into different sets or clusters by their distance.In general,these clusters have no special rule during clustering,therefore more particular clustering is needed that is solved by specific Algorithms.
The CF tree is described by the following format.CF={N,LS,SS},N is the number of points in the data set,LS is the liner sum of points in the data set,SS is the square sum of points in the data set.

The results show: the reduction of pile spacing and the settings of pile cap can decrease the settlement of soil among the piles on foundation plane.
The data indicates that the reduction of pile spacing can decrease settlement in large scale.
In a word, both the reduction of pile spacing and setting of pile caps can decrease the settlement of soil among piles. 2) Settlement regularity of soil among piles in pile-tip layer The settlement of soil among piles in pile-tip layer appears to be basin shape.
Conclusions By establishing a three-dimensional model, this paper analyzed the settlement regularity of deep soft soil and drawn the conclusions as follows: 1) The reduction of pile spacing and setting of pile cap can decrease the settlement of soil among piles on foundation plane; 2) The impact of pile caps acted on soil among piles is different under variable filling height situation.

However, detecting the land cover change in global and continental scale through Landsat or SPOT data has obvious defects: the lacking of right analysis, the long cycle of high spatial resolution remote sensing data, small-coverage and high cost.
Especially, the study is lacking of the comprehensive integration by diversification of massive data.
Analysis of the spatial distribution of carbon sink based on remote sensing data and forest Data is not only making full use of the accuracy of remote sensing space position, but also the advantages of ground scrutinizing data used to estimate carbon storage.
This paper introduces obtaining land cover information by remote sensing data to evaluate NPP.
Also, this paper states measures to enhance carbon sink and provide data evidence to make policy measures for carbon reduction.

By this way a reduction in thrust force and torque is expected, having temporarily changed the material properties.
The reduction of lubricants is also expected, making the issue very important for ecological and economic reasons.
The signals were sent to a digital data acquisition system for storage and subsequently, a computer was used for data handling and analysis.
The reduction relative to Mz, with a minimum of 80°C, appears especially significant.
Tab. 4 reports the maximum force thrust and torque reduction percentage in hot drilling of Al6061/SiCw.

Analysis of results demonstrates that core drilling can remarkably reduce the strength of structural elements, moreover as a consequence of cross section reduction (temporary effect).
In fact, it must be emphasized that restoration can be difficult or even ineffective in low strength concrete, thus leading to permanent reduction of cross section.
However, drilling out of core from a structural element results in capacity reduction which may lead a structure to an anticipated risk.
Then the four LVDT connected with data logger and computer program to record the strain of column.
The failure was brittle since the load decreased suddenly when the concrete cover spalled off. 4- Conclusions Based on the previous data, the following conclusions can be drawn: · Taking core at the middle height has lower effect on the column capacity than taking it at the third height of the column Therefore, the half-height is the best location for taking core drilling

This work provides some guidance for further study of vibration and noise reduction of the soil stabilizer.
It can identify noise sources of cab with the reduction of driver as single-output[4].
Identification of vehicle radiated noise source based on partial coherence analysis is used rarely because that it is difficult to define the output reduction.
Based on time domain data and , the spectral and cross-spectral can be achieved by programming.

Temperature-programmed reduction (TPR) analysis was conducted with a Quantachrome ChemBET 3000 instrument.
Table 1 presented the nitrogen physisorption data for NiMo sulfide samples, showing BET surface area (SBET) values of 322 m2·g-1, 280 m2·g-1 and 120 m2·g-1 for NiMoS-FM, NiMoS-FM-rapid and NiMoS-H2O, respectively.

Table 2 showed the initial rate constants determined by a linear fit of the experimental data according to the equation described by Huang et al[7].
For the NiMoW-Al2O3 catalyst, two main peaks were observed at 263 and 330 °C. the first TPR peak can be further interpreted as reduction of CoMoS(NiMoS) phase, and the second peak is referred as reduction of unpromoted MoS2 or WS2 phase[8].

The atomization can be improved through a combustion chamber which contributes to emission reduction by shortening the nozzle orifice diameter.
It was commonly believed that the purpose of high injection pressure was the reduction of PM and the injection timing was retarded so as to reduce NOx [18]..
Figure 7: Effect of Ambient Pressure on Ignition Delay τ1 and τ1 + τ2 [22] Figure 5: pf - pa and pf - pn versus time [10] The lower injection of 30 MPa and a Pa of 4.2 MPa data from Arrehenius have been plotted as show in Figure 7.
The injection of 14 MPa and a Pa of 3.8 MPa are also plotted by Ikegami and Miwa [23] from their experiment data.
The different injection pressure of 14, 30 and 100 MPa was obtained from the data.

Another statistics published by Western Europe on data gathered from individual plant showed that 10% to 15% of pipework failures are caused by vibration induced fatigue [1].
This paper reviews on the causes of piping vibration, some health monitoring techniques, piping vibration assessment and reduction methods specifically caused by pressure pulsation phenomenon were also presented.
A qualitative assessment, visual inspection and basic measurement are being performed to indentify area of concerns and problem based on measured data.
Special measurement techniques such as Dynamic Strain Measurement and Fatigue Analysis, Experimental Modal Analysis, Operational Deflection Shape and Dynamic Pressure (pulsation) Measurement usually applied to acquire more data for diagnosis purpose.
For reduction of piping vibration, passive control devices offer cheaper price than active control device.

Rolling scheduling is an important part in the operation of tandem cold mill, which defines stand reductions, tensions, rolling forces, roll torque, mill maximum speeds, and threading adjustments.
(4) where N is roll power, ε is reduction rate, and n is roller’s speed Rolling Force Formula.
The fifth stand usually functions to flatten the strip, thus in this simulation, the reduction of the fifth stand remains unchanged.
According the data from Table 1, a notable reduction of electric power cost is shown, which is about 20 %.
A considerable reduction of power cost can be achieved.
