A general modeling mode was proposed and the predictive model of energy consumption and several performances like chemical compositions was established by history data of sintering.
In this paper, we mine the historical data of a typical iron and steel enterprise and build a predictive model of energy consumption and performance indicators based on SVR in sintering process.
For a data set G=xi,yi,xi∈Rn,yi∈R denotes the input vectors and target values respectively.
If the data is positioned in this tube ε, the loss function can be regard as 0.
So we need to normalize our original data into intervals of [0.2, 0.8].

At present, many scholars are to force in the endpoint effect[4,5],for example, waveform data extension,time series prediction extension,distance endpoint prolongation,polynomial fitting, regression model processing, extreme mirror continuation, etc..
The second IMF component is established on the residual item of the original signal data minus the first IMF,and so on .Leading to fitting errors to gradually spread, false IMF component produce.
From separate , get a new data sequence
From separate , get a new data sequence removing the high frequency components of the IMF

Wireless communication technology is adopted to transfer data between devices.
(1) Handhold operator The operator is mainly used for system maintenance and management, and for data read and clearance.
For the other, on-off controller can backup running data to prevent data loss when power-down accidentally happens
One transponder can support data transmitting between multiple remoters and controllers.

The collected data was utilized as the boundary condition for the CFD simulation for further prediction of the model.
The results of the simulations were compared with the real time outdoor weather data as the benchmark of thermal performance of the indoor environment
In order to obtain the real time weather data, HOBO U30 weather station was set up at the case study house compound.
The field measurement weather data as shown in Table 1 was input as the boundary condition for the CFD simulation.

But passenger transportation energy consumption intensity has not increased according to passenger transportation energy consumption data from reference [3], as is shown in figure 1.
Considering the reliability of the calculation data acquisition and the feasibility of data analysis, we use annual statistical data of national bureau of statistics.
Comprehensively considering the data availability and consistent with the statistical yearbook, the research takes 1990-2007 as sample period.
The whole society passenger transport turnover volume and transport structure data is from China's transportation yearbook [6].
Because China's energy yearbook [7] doesn’t list passenger transportation energy consumption volume separately, passenger transport energy consumption data is from the reference [3].

Using comparative genomics and metabolic reconstruction strategies, a putative pathway was detected for C1 fixation consisting of four main steps: 1) conversion of carbon monoxide to carbon dioxide with gain of energy and/or 2) reduction of carbon dioxide to formate, 3) incorporation of formate to tetrahydrofolate and 4) donation of the carbon moiety of tetrahydrofolate to glycine to produce serine.
Using this genomic data, bioinformatics and comparative genomic strategies, we aimed to establish which genes and reactions could be implicated in carbon fixation in Ferroplasma spp.
Scheme of the CO2 fixation pathway reconstructed from partial genomic data of Ferroplasma genomes.
This prediction is compatible with some previous experimental data: according to the chimaeric pathway, these Ferroplasma strains need glycine specifically to fix CO2, and thus the amino acid is required in the growth medium, explaining why Ferroplasma requires low yeast extract for growth.

This behavior is advantageous for the use in magnetic data storage and electronic devices [10].
NiCr thus combines self-assembly potential with ferromagnetic behavior, as required for magnetic data storage applications.
The AFM analysis is performed in order to obtain the characteristics (diameter, height) of single NPs and statistical data of NP ensembles.
This property is ideal for data storage applications because this allow the ring to have two possible states (binary) in the alignment of the magnetic dipoles in the rings, clock-wise or counter clock-wise.
Grain size and particle analysis was also performed for the deposited nanorings to yield statistical data about their dimensions in Fig. 3 c) and d).

The rotational stiffness and strength obtained from the numerical modelling are then compared to the design requirements from BS EN 1993-1-8 and experimental data.
Reduction in cost can be done by adopting semi-rigid connection into building design.
Since there is no tested data for bolt, elastic-perfectly-plastic behaviour was assigned as the material property to the model of bolt.
According to Table 1, in predicting the values of the joint resistance, the finite element models have a good agreement with experimental data.
The 6 mm flange-cleat finite element models has achieved a good agreement with experimental data.

XRD data were collected for the 24 h milled powder of Fe-Mn-C after being annealed at 400 °C, 500 °C, and 600 °C and maintained for 4 h.
This reduction is more significant in the first few hours of milling, and the microstrain increases to 1.066 % after 24 h of milling.
We observe a reduction in the lattice parameter at the initial stages of milling to a value of 2.8642 Å followed by an increase to 2.8657 Å after 24 h of milling.
The reduction in the lattice parameter at the initial stage may be explained by the refinement phenomenon, while with prolonged milling time, the dissolution of alloying elements into the Fe lattice eventually causes an increase in the lattice parameter.
Furthermore, according to the X-ray structural analysis data (Figure 5), the austenite formed during mechanical milling disappears after annealing.
