To meet the sectional lamps management requirement, software of SDACS provides functions of real-time data acquisition, basic data stat and analysis, lamps control and data output as shown in Fig  4.
Polling flow chat Specific data structure is designed to collect real-time data.
The system succeeds in data acquisition and lamp control.
The time cost on sending a single data instruction is estimated as 144*100/50000=0.288 seconds, data volume transfer through GPRS each day is 144*100*12*12=2.073 Mb.
As a result of the reduction of both data sending frequency and transferred volume, system energy is saved greatly and living life is extended.

The knowledge of the mechanism of SFs reduction is crucial for the development of a high quality material for devices fabrication.
Despite the great amount of work on the hetero-epitaxy of 3C-SiC, the mechanism of SFs reduction is not completely clear.
The data were represented through Reciprocal Space Maps [12] in the qx-qz scale as shown in Fig. 1.
By cross-section TEM it was consistently found that SFs density is reduced far from the original interface, in full agreement with the HR-XRD data.
So homo-epitaxy is an alternative solution to the growth of 3C-SiC on compliant substrates for the reduction of defects in the material.

The scaled El Centro 1940 earthquake data is used as input excitation.
In order to evaluate the performance of the newly developed TMD, dynamic tests are performed by employing scaled El Centro 1940 earthquake data [8].
Input excitations: (a) original El Centro 1940 earthquake data, (b) scaled data for 20 sec and (c) scaled data for 25 sec Herein the scaled El Centro 1940 is employed due to the existing laboratory setup.
The input excitation such as El Centro data remains same as experimental tests input (see Fig. 6) for the simulations.
Along with the full-time history, a zoomed view of 0-5 sec are also provided for better visualization of the data.

According to calculated and given data to calculate primary energy consumption, CO2emission, initial cost, annual operation costs and payback periods.
At present, Changchun has very little data on hourly heating loads and electricity loads.
Cost and performance data for on-site electricity systems are estimated from available data, as are the prices and CO2 intensities of natural gas and electricity.
With the cost, performance, and emissions data, energy consumption, CO2 emissions and site energy costs are obtained.
The energy loads data is gained according to Ojima's annual hourly energy unit and yearly energy consumption intensity [5].

Introduction In the fourth generation (4G) wireless communication, Orthogonal Frequency Division Multiplexing is one of the standard multi-carrier attractive technology, here a high data rate stream is split into a number of lower data rate streams that are simultaneously transmitted over a number of sub carriers.
The average signal power of input data sequence is the peak value of the auto correlation [4-7,12].
When the DCT is applied to the data sequence, many zero elements appear in the DCT transformed sequence but the sequence structure is not changed.
In this system, the adjacent two input data symbols are jointly mapped to a single sub-carrier, and then the frequency separation between the sub-carrier is increased.
After DCT transformed , the peak power of input data sequence X DCT is expressed as (19) After DCT many data sequence values are very small and some zero elements will be appear in the DCT transformed sequence.

The extraction data for the system macaúba oil + free fatty acids + ethanol + water was determined for oil:solvent mass ratios 1:1.
For equilibrium data comparison, the extraction and cooling processes was carried out for 24 hours.
From the statistical data in Pareto chart (Fig. 1) it can be concluded that temperature and water content in ethanol has not a significant effect (p < 0.05) in the FFA reduction.
As the stages number increased of 1 to 3, the FFA reduction increased of 20 to 60% (Fig. 3).
According literature data, the solubility of TAG in ethanol increases in direct proportion to their FFA contents [10].

The data of total clinker productions tems from the China Cement Almanac and relevant literature survey[4], asshownin Table 2.

Given this situation, we first took data from the literature review from the China Cement Association, and when other wise not available,we complete the time-series data with the data from other literatures.
Some SEC data for single years are estimated according to other literatures.
Despite this uncertainty, the resulting time-series data set is judged sufficiently robust for the analysis and shows noun explainable out liersorpeaks.

The method includes the following steps, pretreatment, feature extraction by WPD and dimensionality reduction by LPP and classification of the test samples to a corresponding class according to the nearest neighbor classifier.
Wavelet packet decomposition of gait energy image Wavelet packet decomposition (WPD) is a wavelet transform where the discrete-time (sampled) data is passed through more filters than the discrete wavelet decomposition  (DWD) [11,12].
The direct use of the gait cycle gait recognition exists huge amount of data, increasing the difficulty of gait feature extraction and calculation of consumption, in order to guarantee not to abandon the gait characteristics while reducing pending gait amount of image data, gait energy image (GEI) is used to last cycle through a number of gait image synthesized by the method of weighted average image, this image contains a gait cycle each gait image contour, frequency, phase, etc. gait information.
Other image processing applications such as noise reduction, edge detection, and gait analysis is as in Ref. [5, 6, 7, 10].
