Research Methods and Data Collection Research Methods.
(3) The calculating and judging of the forest and grassland carbon absorption coefficients are based on empirical data from the previous studies.Owing to the lack of energy consumption data of “Statistical Yearbook” and relevant statistical data, it calculates and predicts the total energy consumption through analyzing the relationship between energy consumption and economic growth in G.D. on this paper.
This paper adopted the current data of land use in G.D.
While some cities’ developing data obtaining from City Development Planning of Guangdong Province (2006-2010)”.
Among them, the data of Land-use planning of 2010 were obtained from Land Using Planning Outline of Guangdong Province” (2006-2020).

Currently, the integrity evaluation is based on the analysis of temperature, and pressure data registered on a continuous data base over a period considered adequate by the station supervisor.
This curve is drawn using the ASME Code data [4] as shown in Figure 1.
The system used, named Monitermo, was developed at CEPEL, and is based on WEB technology, Postgres data bank and Field Point platform, from National Instruments, for data acquisition.
Data are stored periodically in a data bank that can be accessed via internet.
The use of a monitoring system in real time gives a faster response, allowing more precise remaining life calculations through reduction of errors from the manual method and refinement of the data used.

A life prediction was then carried out using constant amplitude compression dominated loading for various exfoliation corrosion levels by AFGROW, and the prediction agreed reasonably with the available test data.
The radius of this initial discontinuity for the LY12CZ has been determined to be 0.084mm based upon numerous correlation trials to experimental data [5].
The plots also show that a sharp reduction in fatigue life occurs very early in the exfoliation process as the surface damaged.
Based on the data in current analysis, a pit depth about 0.3mm would be an appropriate value.
A limited set of fatigue life data from tests demonstrated that this model is reasonable.

Completeness of chemical reactions was taken into account in calculations based on thermodynamic analysis and technological data.
The calculation results correspond to the technological data.
The literature data on the enthalpy of the ferromanganese smelting products are not numerous and differ significantly from each other.
The window for entering the initial parameters The program includes data of technological parameters.
In addition, there is the possibility of changing the initial data for the release of another grade.

Hence, a variety of routes such as photolytic reduction [4], radiolytic reduction [5-6], sonochemical method [7], polyol process [8,9], alcohol reduction [10,11] and organic solvent reduction were reported for the preparation of metal nanoparticles (Pt, Pd, Au and Ag) [12].
Several examples exist on the reduction of metallic salts by organic solvents, mainly ethanol.
Usually, these nanocomposites are prepared through blending nanometer metal particles with polymer [15], reduction of polymer-metal ion complexes or metal ions in the polymer solutions with reducing agents [16-18], and reduction of metal ions with the aid of irradiation [19,20] and thermal reduction [21].
Formation of Ag nanoparticles is by in situ reduction of AgNO3, in the presence of DMF, by thermal or UV reduction of PSF/AgNo3 films.
We expect SEM images to confirm our assessments and to find them in good concordance with the other experimental data.

The one of actions for cost reduction is to decrease the defect in operation.
One of the concerned cases is the reduction of spindle motor defects in vibration process [2].
With the data collection during December 2011-November 2012, an average part per million (ppm) per month of 3*3 QFN defect is 5,913 resulted in a company cost of 574,566 Baht per year.
The process capability index is calculated with the same data from 250 samples.

During the field research the facts were observed and taken data collection.
Following, it was made the analysis and interpretation of the collected data.
In Figure 7 there are partial data from the implementation of LEED in the work of Maracanã referring to February 2011.
This is the result of a first data collection of points aimed at sustainability in the construction site of Maracanã.
In Figure 8 are the final certification process data from LEED, dating from May 2013.

Data set The data set taken from Chou and Cai [5] are used to test the current method.
If the high-dimensional data lies on or near a curved manifold, such as in the Swissroll dataset, MDS might consider two data points as near points, whereas their distance over the manifold is much larger than the typical interpoint distance.
However, Isomap is a technique that resolves this problem by attempting to preserve pairwise geodesic (or curvilinear) distances between data points.
These neighborhood relations are represented as a neighborhood graphover the data points, with edges of weight between neighboring points. 2.

In this paper first,a method combining dichotomy and finite element is presented which identify elastic modulus parameters of mistuned bladed based on the test data of blade static frequency and simulation blade deliberate mistuned by change elastic modulus.Then, dynamic characteristics of deliberate mistuned 10Hz and 41Hz bladed-disk system were analyzed in work rotating speed based on CMS mothod, respectively.

Dynamics Characteristic Analysis Based on Component Mode Synthesis Method The substructure analysis uses the technique of matrix reduction to reduce the system matrices to a smaller set of DOFs.
Matrix reduction is also used by the reduced modal, reduced harmonic and reduced transient analyses.
Conclusions In this paper ,a method combining dichotomy and finite element is presented which identify elastic modulus parameters of mistuned bladed based on the test data of blade static frequency and the simulate of blade deliberate mistuned by change elastic modulus.Then,dynamic characteristics of deliberate mistuned 10Hz and 41Hz bladed-disk system were analyzed in work rotating speed based on CMS substructure mothod, respectively.The investigate results show that along with the mistuning frequency difference increases,the largest amplitude of blade is becoming smaller(except tuned system); and scheme of large frequency difference 41Hz deliberate mistuned (scheme Ⅱ) better than scheme of small frequency difference 10Hz deliberate mistuned (scheme Ⅰ) for vibration reduction of bladed-disk system in work rotating speed for 11300r/min.
