Except to enhance the conductivity and the mean operation voltage, a high capacity was also expected for the LiFePO4-based Li ion batteries. 2 Experimental The LiFe0.98Ni0.01Nb0.01PO4/C was synthesized by means of carbon reduction route using FePO4·2H2O as precursor.
The data were collected in the range between 10 and 90° in steps of 10°/min.
Conclusions The LiFe0.98Ni0.01Nb0.01PO4/C composite was synthesized carbon reduction route using FePO4·2H2O as precursor.

Data collection for medical data warehouse research Yuke Chen1,a , Taixiang Zhao1,b 1Department of foundation, First Aeronautic Institute of the Air Force ,Xinyang, China ayuke_chen@sohu.com, bZtx304@126.com Keywords: Data warehouse, Heterogeneous sources, Project management Abstract.We propose an easy method for data collection and central data warehouse design.
Basically, our data gathering and data organization was repeated three times, each time trying to avoid previous mistakes.
Finally, we advise that for data gathering in general, one should identify the critical requirements first.Typical requirements are high levels of data privacy, data accuracy, analysis speed, ability to filter large amounts of data, good connectedness, short-term data availability, etc.
This will reduce the scope of the data gathered and will simplify the schemas of the data repository.
In our case, the scope reduction was also a consequence of the analysis tools that have been already developed.

This approach can also be used to target recognition based on radar data.
Moreover, without dimension reduction, the model’s complexity is high and the learning speed is low.
Assume the original input data has been normalized.
The spectral data come from http://www.ucl.ac.be.
The dimension of the mass-spectrometric data for building mode is 1000.

From the analysis of microstructure, it is thought that the HIC contribute dominantly to the reduction in the fatigue life in the strain rate range from 0.04 to 0.4 %/s and the metal dissolution is mainly responsible for the reduction in the fatigue life at the strain rate of 0.008 %/s.
Although the LCF data of various LASs in high temperature water have been produced up to recently, the data of SA508 Gr.1a LAS used as piping material in Korean nuclear power plant is insufficient.
In this regard, the LCF tests were carried out to produce the fatigue life data of SA508 Gr.1a LAS used in Korean nuclear power plant.
For comparison, the ASME design fatigue curves and the fatigue life data in air are also shown in Figure 1 [8].

For other companies lack of data, the missing data are replaced with industry average data after excluding extremely high values and abnormal low values.
(2) Data standardization.
Transform the data into the interval [0, 1].
(3) Data discretization.
Input data matrix is the data after preprocessing.

This paper will discuss what are cloud computing data centers, cloud computing data center construction, cloud computing data center architecture, cloud computing data center management and maintenance, and the relationship between cloud computing data centers and clouds.
Cloud Computing Data Center Construction Construction of cloud computing data centers is a system, a complex and iterative process.
Data Storage and Backup.
The data handled by user are not stored locally, but in the data center of the Internet.
All the data is handled remotely.

Variable precision rough set(VPRS) model and formal concept analysis are studied in this paper, include algorithm of reduction attribute and extraction rule.

Qiang Xu, et al. systemically analyzed and researched variation of cumulative displacement, deformation rate and acceleration of landslide from the beginning of deformation to instability failure relying on a large number of monitoring data of landslide deformation, and found that variation of acceleration was completely different from cumulative displacement and deformation rate.
By integration analysis of monitoring data of typical section, curves of horizontal and vertical displacement with time were drawn, shown in Figure 1.
By integration analysis of monitoring data of typical inclinometer hole, deep displacement curves with depth were drawn, shown in Figure 2.
