In this paper, a JPEG steganalysis algorithm based on locality preserving projection (LPP) dimensionality reduction method is proposed for detecting the unseen stego algorithms.
In section 3, the algrithm of feature dimensionality reduction, which use LPP method, is described.
The steganalysis features are as follows: (18) 3 Features Dimensionality Reductions Based on LPP The Locality Preserving Projection (LPP) is a linear approximation of the nonlinear Laplacian Eigenmap [5] .It is an unsupervised technique which is always used to reduce the dimension of feature and aims to preserve the local neighborhood structure of the patterns after the linear dimensionality reduction.
Summary For detecting the unseen stego algorithms and reduce the feature dimension, a JPEG steganalysis algorithm based on locality preserving projection (LPP) dimensionality reduction method is proposed.

The FT-IR and Raman results showed that the reduction degree of GO to rGO was increased with the rising of the reaction temperature and time.
The optimal condition of the chemical reduction of GO to achievable rGO was the temperature of 90 °C with the 45 min of heating time.
Then, all the synthesized rGO samples were characterized by spectroscopy techniques to analyze the reduction degree of GO.
These data confirmed that the reduction degrees of GO convert to rGO are increased over the chemical reduction method by using vitamin C as a reductant, this result is consistent with previous reports [2,6,7].
The color change in the GO suspension afetr reduction is confirmed that GO is reduced to rGO as same as previous papers [1,3,5,6].

The technologies bring with the building a reduction 6.5 kt CO2 each year.
The sustainable design of the building would have a reduction of about 6 kt CO2 annually.
It means that the solar PV of China pavilion contributes GHG reduction of 552 t CO2e.
The CO2 reduction attributable to the green measures would amount to 6.5 kt CO2 annually.

Therefore sulfide hinders the cathodic reduction of O2 on Q235 carbon steel in 3.5% NaCl solution.
The results of EIS were analyzed with fitting the data using Zsimpwin software.
For N2-saturated solution, hydrogen evolution reaction (HER) occurs at potentials more negative than-1.20 V (Fig. 1a), and the reduction peak at −1.15V is attributed to iron oxides reduction[15].
The peak at -0.93V and −1.15V are attributed to ORR and iron oxides reduction, respectively.
The variation of electrode surface restrains the reduction reaction of O2 and iron oxides.

Minimum Noise Fraction was used for dimension reduction.
And then the RX algorithm and KRX algorithm was used to detect the data after dimensional reduction.
And it indicates a lattice in high-dimensional space if hyper spectral data is considered as a collection of multi-data.
There are tow main problems for entire anomaly detection: firstly the background is so complicated that would probably leads to over-anomaly detection, secondly the comparatively low level of objectives would leads to higher false alarm rate and lower detection and minimum noise fraction is used for dimension reduction of data aiming at the disadvantage of large number of data for hyper spectral images.
The spatial size of the data is of 100 × 100 pixels, containing 38 targets to be detected.

Electrocatalytical reduction of CO2; Recycling utilization of CO2.
Our aim is to provide the basic data for fundamental research of CO2 electrochemical reduction.
In previous work, many researcher selected Ag electrode as the cathode for CO2 electrochemical reduction to suppress hydrogen evolution and improve the Faradaic efficiency of CO2 reduction.
The increase of the current density is attributed to the reduction of CO2.

The results showed that the catalytic activity of TNCuPc/AF-MWCNTs towards oxygen reduction was a two-step, two-electron process for oxygen reduction.
CV of GC/ TNCuPc shows two reduction peak ( −0.45 and -0.74 V vs.
and (c) TNCuPc/AF-MWCNTs , the oxygen reduction peaks were at similar positions(-0.50 and -0.75V vs.
From the result, GC/TNCuPc shows a two-electron process for oxygen reduction (Fig. 8A).
However, GC/TNCuPc/AF-MWCNTs led to a two-step, two-electron process for oxygen reduction.
