Data sources.
Hydrological data were the water flow data from Baoqing hydrometric station during 1956~2005.
The land use/cover change data is extracted from literature (SONG, 2008).
Data analyses.
Data were processed using Matlab 6.5, and Excel 2003 software.

What’s more, the data collection and arrangement of drilling, logging, geophysical prospecting and test should be strengthened.
Meanwhile, the implement of navigational drilling technology (PDC bit + screw + MWD), to be more specific, using the MWD to monitor the data of hole deviation, location, gamma value, based on which we can adjust the tool face of power drilling tool in order to control the wellbore trajectory precisely.
Based on the record data coming from downhole engineering parameters measuring instrument and logging data, we calculated the ROP in two different drilling ways with different drilling pressure and displacement (sliding drilling with unchanged displacement), as shown in table 1 and table 2.
Therefore, during long horizontal section of horizontal well drilling, considering the reduction of drill string friction and torque, the rigid larger drill collar should be avoid using.
Through studying the measured data after adjusting the drilling parameters, this paper found that intensifying the drilling parameters reasonably is an effective way to improve ROP.

Six parameters in the modified Ramberg-Osgood equation were determined by fitting to the experimental stress-strain data using a least-squares fit.
The recorded signal data are neither smoothed nor averaged electronically.
The constants H and n were determined by fitting Eq. (7) to the data points on the s -ep curves using a least-squares fit, where H corresponds to the value of s at ep = 1.
A value of R2 (coefficient of determination) indicates a measure of the goodness of fit to the experimental data.
The six parameters a, b, c, d, p and q were determined by performing the least-squares fit to three sets of measured data points (solid symbols) using Eqs. (11) to (13).

The life was calculated at three accelerated aging temperatures i.e. 130,140 and 150 °C and then this data was extrapolated to lower temperatures.
Service life is predicted by extrapolation of the given data points.
The life of ESB was estimated by the 50% reduction in elongation at break (EAB) criterion.
After thermal aging a clear reduction in tensile strength was observed [42–44].

The FE results were combined with the test data, in attempt to relate the numerically predicted damage to the cage life.
This is possible by having the experimental data relating the fibers density to strength along few directions.
Experimental data from the fatigue test.
Outcome of statistical analysis applied to the experimental data (in Fig. 10).
The analysis is based on L10, and since the data is scarce a 2-sided confidence interval of 90% is used [35].

Isothermal compression tests of the two component materials were carried out using Gleeble 1500, in order to obtain their high temperature strength data, as shown in Fig. 2.
The temperatures and pressures data of 100 billets were then processed by Newton Interpolation, as shown in Fig. 3.
By combination of the data in Tables 2 and 3 and Equation (9), the extrusion pressure will be estimated approximately.
Thus, the calculation based on that assumption shows a good agreement with the data obtained from industrial trials, with the error less than 10 %.
Thus, the calculation based on that assumption shows a good agreement with the data obtained from industrial trials, with the error less than 10%.

It is the traditional C/S mode, partial decomposition of the server as a data server and one or more application server (Web server ), and thus form a three-layer structure (3-tier) client-server system.
B/S system, such as SQL Server database server is installed on the client, simply install a browser, the user interface is fully realized through a WWW browser, the browser through the Web Server for data exchange with the database.
(2) the data on the system with high security requirements, requires a strong interaction, requiring large amounts of data processing subsystem using C/S mode of development, it can guarantee the reliability of the results and reduce the computer response time
(3) information dissemination, data entry using B/S structure is conducive to the release of information that will need to publish a notice posted online news in a timely manner, so that all staff receive timely information
For data query, deletions, display, modify functions are done by the database management system

Introduction Spread spectrum technology is now mainly used in spread spectrum communications, navigation systems, tracking and Data Relay Satellite System (TDRSS).
After the input signal is multiplied with the local PN code, each chip's data accumulation, the input data deceleration, then the original chip now become the K point data, K = L/D (if choose K right, you can estimate the value of the frequency shift of the entire range of Doppler shift).
We can use K points data for N(N≥K) point FFT operation and analysis the spectrum.
From (2) can be seen the estimated value is accurate only when the offset is an integer multiple of the frequency resolution (which is for the FFT data accumulated time).
Firstly, if the resolving ambiguity length code does not transmit data, power will be a wasted even if less energy allocation.

Six groups of three-direction vibration data of outer edge of box girder above 29# pier caused by blasting vibration during part-cast period were measured.
From the data, the average attenuation coefficients are 0.357 and 0.642 in longitudinal and transverse respectively, and the average amplification factor is 3.783 in vertical.
Bearing lead on the top of pier is core isolation rubber bearing. 30 groups of three-direction vibration data were measured when the box girder on 31# pier is completely casting.
From 30 groups of three-direction vibration data, the average attenuation coefficients of bridge are 0.678 and 0.941 in longitudinal and transverse respectively.
Conclusions Through analysis of vibration velocity monitoring data from the bottom of piers to the top of box girder of continuous beam bridge in near- blasting area.

More recently, the Single Instruction and Multiple Data (SIMD) technique became commonly used, applying multiple parallel Processing Elements (PEs) to explore Data-Level Parallel (DLP) [5] by operating on multiple data in parallel in a single instruction.
These data rearrangement operations results from column-wise data accesses in matrix multiplications and matrix transposes.
The multiple PEs perform a dot operation on two vector data and then produce a scalar element.
However, the matrix data is usually organized by row-wise.
Thus data rearrangement operations must be performer among multiple PEs.
