When we apply positive voltage to the LSMO surface, reduction is induced in local region and the region switch to HRS.
(a) Sample absorption image by 529 eV and (b) O 1s NEXAFS data of HRS LSMO and LRS LSMO.
The NEXAFS data corresponds to the absorption associated to the dipole-allowed transition where an O 1s electron is excited to unoccupied O 2p orbitals.
The second feature revealed by the HRS data is the increased absorption ‘b’.
The resistive switching was induced by reduction and the field-induced oxygen vacancies doped electrons to partially emptied Mn 3d e1g↑ band (doped hole by Ca2+).

After formula derivation Beltrami got the matrices of SVD:
(1)
Assuming the pure signal and additive noise signal are s[n] and v[n] respectively, where n=0,1,2,···N-1, so the received signal which contains the noise can be expressed as x[n]=s[n]+v[n], N is the length of the analysis of the data, in this paper that is the sampling points of stator current.
(3) SVD algorithm can be summed as [10]: (1) According to the sampling signal x[n], uses equation (2) to build Hankel matrix and takes half the length of the data, i.e, M=L=N/2 ,the remaining sample points discarded
Extended Prony Algorithm As early as 1795, Prony proposed the model using a linear combination of the exponential function to describe the equally spaced sampling data.

The rough set theory can deal with historical load data, and then give new samples from original data.
Rough Sets method of Attributes reduction Rough Sets[9-12] can only deal with uncertainty and discrete data, so when the attribute values of the information is continuous, discreting it is necessary.

Circumstances of both aspects were researched by online questionnaires and data from Taobao, in order to check if there are some deviations between them and further analyze the detailed difference, reasons, and potential impacts which caused the deviations.
In this study, we researched Taobao official data cube to collect the equal information on "brand", "style”, “price" and “goods credit” for the present products recorded from top 45 brands in April.
Based on selling data from Taobao mall the comparison result to the survey data are illustrated in Fig.2.
Analysis on the derivation of actual styles and target styles Fig. 3 Comparison between actual styles and target styles in April Data from Taobao has shown that there is a wider category of menswear online than the traditional market.

Contribution of this paper mainly includes the following two parts: First, proposes a fast clustering algorithm for complex data sets.
This method first put multidimensional feature data into a single value, and then use a variety of hash functions to remapping data.
This method can ensure that the same data is classified as a class, similar data is classified as a class has a large probability.
The main idea is to use multiple hash function hash data points, to ensure for each hash function that the similar data point, the higher to collision.
For the data set G, which contains N samples , for each sample, the data format is , represents recommendation algorithm for recommendation weights, arranged in order of descending.

These
data maybe rearranged yielding up to one million diffractograms (one for each pixel of the CCD)
corresponding to the different sample regions.
To handle this large amount of data various techniques for data reduction and processing have been developed or adapted from other disciplines (for example, data sets from remote sensing have a similar structure - i.e. images from a single scene but at different wavelengths).
The structural variation was, therefore, only perpendicular to this plane allowing integration in the direction of the weld leading to a significant data reduction.
All this led to rather noisy images requiring more sophisticated methods for data reduction [20].
Examples include the development of various sample environments like the above mentioned reaction cells for XAFS but also the implementation of data evaluation procedures to handle the huge amount of data arising from the various imaging techniques.

Apart from being a high k gate oxide, the presence of intrinsic oxygen vacancies as well as ability of Ce4+ state in the oxide to transform to Ce3+ (reduction) state and vice versa (oxidation) [1-4] have motivated research efforts to investigate CeO2 as a gate oxide on Si [5] and 4H-silicon carbide substrates [6-9].
Nevertheless, earlier, it was reported that reducibility of CeO2 happens at an onset temperature of 600°C [10], meaning that reduction of Ce4+ to Ce3+ does not happen at temperatures lower than 600°C.
In order to obtain a statistical significant value of the investigated Qeff, five data have been extracted from each sample and presented using error bars in inset of Fig. 1.
Therefore, as the post-deposition annealing time increases, formation of thicker SiOx IL indicates compensation of much of the oxygen vacancies and thus a reduction in Qeff is obtained.
